Recently, four compulsory national standards, including the Limits of Hazardous Substances in Building Wall Coatings, the Limits of Hazardous Substances in Wood Coatings, the Limits of Hazardous Substances in Vehicle Coatings, and the Limits of Hazardous Substances in Industrial Protective Coatings, were sought for comments. It is reported that the implementation date of the four standard recommendations is July 2020.

Tu reporters noticed that the "Limits of Hazardous Substances in Building Wall Coatings" standard replaced GB 18582-2008 "Limits of Hazardous Substances in Interior Wall Decoration Materials" and GB 24408-2009 "Hazardous Substances in Exterior Wall Coatings for Buildings" Limited. Compared with GB 18582-2008 and GB 24408-2009, the new standard adds decorative board coating products, increases the total lead content of water-based interior wall coatings, the total content of alkylphenol polyoxyethylene ether, and the total amount of phthalates Four control items such as content; revised limit value of volatile organic compound content, more stringent indicators; revised limit value of free formaldehyde content, more stringent indicators; revised limit value of total lead content of water-based exterior wall coatings, indicators More strict wait.

标准 The standard stipulates the terms and definitions, product classification, requirements, test methods, inspection rules, packaging marks and other contents of allowable limits for substances harmful to humans and the environment in architectural wall coatings. The standard is applicable to all kinds of architectural wall coatings used for direct on-site painting and factory coating to decorate and protect the inner and outer surfaces of buildings based on cement-based and other non-metal materials.

The main drafters of this standard include: Sankeshu Paint Co., Ltd., Hebei Chenyang Industry and Trade Group Co., Ltd., Guangdong Bardez Chemical Co., Ltd., Jiabaoli Chemical Group Co., Ltd., Zhuhai Zhanchen New Materials Co., Ltd. State Coatings (China) Co., Ltd., Guangdong China Resources Coatings Co., Ltd., Pompeijing Coatings (Shanghai) Co., Ltd., Mei Chao Group Co., Ltd., DuPont China Group Co., Ltd., Vanke Enterprise Co., Ltd., etc.

The State Council issued the “Notice on Printing and Distributing a Three-year Action Plan to Win the Blue Sky Defense War”, which clearly requires that by 2020, total VOC emissions be reduced by more than 10% compared with 2015. When the standard was revised, the VOC index has been greatly improved. After analysis and calculation of the standard, the VOC reduction in the field of architectural wall coatings can be reduced by more than 58.1%.

Tu reporters noticed that the "Limits of Hazardous Substances in Wood Coatings" standard replaced GB 18581-2009 "Limits of Hazardous Substances in Solvent-based Wood Coatings for Interior Decoration Materials" and GB 24410-2009 "Hazardous Substances in Waterborne Wood Coatings for Interior Decoration Materials" Limited. Compared with GB 18581-2009 and GB 24410-2009, the new standard adds two types of wood coatings: radiation-curable wood coatings and powder wood coatings; added unsaturated polyester solvent-based wood coatings; modified the volatility Limits of the content of organic solvents (VOC), more stringent indicators; revised control names and limits of formaldehyde content, more stringent indicators; revised the sum of benzene content, toluene and xylene (containing ethylbenzene) in solvent-based wood coatings The limit value of the content is more strict; the limit value of the total content of benzene series in waterborne wood coatings is modified; the indicator is more stringent; the limit value of the total content of free diisocyanate is modified; the indicator is more stringent; etc.

标准 The standard specifies the terms and definitions of allowable limits for substances harmful to humans and the environment in wood coatings, product classification, requirements, test methods, inspection rules, packaging marks and other contents. The standard applies to all kinds of wood coatings, including putty, primer and topcoat, which are directly painted on-site or in the factory, except for special functional coatings, to decorate and protect the surface of wooden products.

The main drafters of this standard include: Jiabaoli Chemical Group Co., Ltd., Sankeshu Coating Co., Ltd., Hebei Chenyang Industry and Trade Group Co., Ltd., Guangdong Bardez Chemical Co., Ltd., Zhuhai Zhanchen New Materials Co., Ltd., and Dongguan Dabao Chemical Products Co., Ltd., China Paint (Shenzhen) Co., Ltd., Guangdong China Resources Coatings Co., Ltd., Aoda Koala Coatings (Huizhou) Co., Ltd., Wanhua Chemical Group Co., Ltd., etc.

In recent years, local and regional laws and regulations or rules have been introduced in accordance with the "Air Pollution Control Law" and "Winning the Defense of the Blue Sky" to encourage the use of coating products with low volatile organic content. After years of efforts by the environmental label certification agency under the Ministry of Ecology and Environmental Protection, "Technical Requirements for Environmental Labeling Products for Solvent-Based Wood Coatings for Interior Decoration" has been recognized by many coatings companies. Solvent-based wood coatings must be upgraded by technology. Traditional The high-risk and high-polluting wood coating products must go through the factory coating road, and the on-site coating will inevitably be phased out. Based on these factors, it is recommended that the implementation date of the standard be July 2020.

The reporters from the paint industry noticed that the “Limit of Hazardous Substances in Vehicle Coatings” standard replaces GB 24409-2009 “Limit of Hazardous Substances in Automotive Coatings”. Compared with the original standard, the new standard increases the types of vehicles in the scope, modifies the classification of vehicle coatings, and increases the control of volatile organic compound (VOC) content in water-based vehicle coatings and radiation-curable (water-based) vehicle coatings. The project revised the limit values ​​of the content of volatile organic compounds (VOC) in solvent-based vehicle coatings, the total content of toluene and xylene (including ethylbenzene), and more stringent indicators.

This standard is provided by Donglai Coating Technology (Shanghai) Co., Ltd., Hebei Chenyang Industry and Trade Group Co., Ltd., BASF China Co., Ltd., PPG Coating (Tianjin) Co., Ltd., Nippon Industrial Coatings (Shanghai) Co., Ltd., Hunan Xiangjiang Kansai Coatings Co., Ltd., Guangzhou Jitai Chemical Co., Ltd., Shanghai Jinlitai Chemical Co., Ltd., Shaanxi Baotashan Paint Co., Ltd., CRRC Qingdao Sifang Vehicle Research Institute Co., Ltd. and other units mainly drafted and compiled.

标准 The standard stipulates the terms and definitions, product classification, requirements, test methods, inspection rules, packaging marks and other contents of the allowable limits for substances harmful to humans and the environment in various types of vehicle coatings. Standards are applicable to various types of automotive original coatings, automotive repair coatings, rail transit vehicle coatings, automotive and rail transit vehicle component coatings, and other vehicles (special operation vehicles, low-speed vehicles, trailers), except putty and special functional coatings. , Motorcycles, electric bicycles, bicycles, etc.) and their component coatings. The standard does not apply to coatings for tractor transport units and non-road mobile machinery.

With the development of China's vehicle industry, vehicle coatings occupy a large market share in China's total coatings, most of which are conventional solvent-based coatings. In recent years, various localities have issued local or regional laws and regulations or rules and regulations in accordance with the "Air Pollution Control Law" and "Winning the Defense of the Blue Sky" to encourage the use of coating products with low volatile organic content. Therefore, under the increasing pressure of environmental protection, vehicle coatings companies must upgrade their technology, and traditional high-risk and high-polluting vehicle coating products will inevitably be phased out. Based on these factors, it is recommended that the implementation date of the standard be July 2020.

The reporters from the coating industry noticed that the "Limit of Hazardous Substances in Industrial Protective Coatings" standard replaced GB 30981-2014 "Limits of Hazardous Substances in Anticorrosive Coatings for Construction Steel Structures". Compared with the original standard, the new standard adds four types of industrial protective coatings: water-based coatings, solvent-free coatings, radiation-curing coatings, and powder coatings; coatings for machinery and equipment, concrete protective coatings, container coatings, and pre-coated coil coatings , Packaging coatings, profile coatings, electronic and electrical coatings and other industrial protective coatings; revised the limit of volatile organic compound (VOC) content, more stringent indicators; etc.

The standard specifies the terms and definitions, product classification, requirements, test methods, inspection rules, packaging marks and other contents of the allowable limits of substances harmful to humans and the environment in industrial protective coatings. The standard is applicable to all kinds of industrial protective coatings for protecting metal, concrete, plastic and other surfaces except putty and special functional coatings. The standard does not apply to aerospace coatings and nuclear power coatings.

The main drafters of this standard include: Jiangsu Lanling Polymer Materials Co., Ltd., Hebei Chenyang Industry and Trade Group Co., Ltd., Shaanxi Baotashan Paint Co., Ltd., Donglai Coating Technology (Shanghai) Co., Ltd., and PPG Coating (Tianjin) Co., Ltd., Nippon Industrial Coatings (Shanghai) Co., Ltd., Guangzhou Jitai Chemical Co., Ltd., Smelting New Materials Co., Ltd., Jiangsu Jinling Special Coating Co., Ltd., Shanghai Huayi Coating Co., Ltd.

The State Council issued the “Notice on Printing and Distributing a Three-year Action Plan to Win the Blue Sky Defense War”, which clearly requires that by 2020, total VOC emissions be reduced by more than 10% compared with 2015. When the standard was revised, the VOC index has been greatly improved. After analysis and calculation of the standard, it is time for VOC reduction in the field of industrial protective coatings to be reduced by about 10%. With the transformation from "oil to water" and "paint to powder", VOC emission reduction will further increase.

Industrial protective coatings account for about 50% of China's total coatings, most of which are conventional solvent-based coatings. In recent years, various regions have issued local or regional regulations in accordance with the "Air Pollution Control Law" and "Winning the Defense of the Blue Sky". Laws and regulations or rules and regulations encourage the use of coating products with low volatile organic content. Therefore, under the increasing pressure of environmental protection, many non-standard small factories will soon be eliminated naturally. For the standard industrial protective coatings enterprises, the only way is to upgrade the technology, traditional high-risk and high-pollution industrial protection. Coating products must be phased out. Based on these factors, it is recommended that the implementation date of the standard be July 2020.
