Introduction

Human beings have a long history of producing and using coatings. Coatings have made important contributions to the development of human society and will continue to develop in the future. Play a greater role. The safety of coatings is closely related to the health of consumers, and industrial coatings have always been an important area in air pollution prevention and control programs. In recent years, environmentally friendly coatings such as water-based coatings, high-solid coatings, solvent-free coatings, low-VOC radiation-cured coatings, and powder coatings have been Under the guidance of my country's environmental protection work requirements and industrial policies, it has made great progress, and VOC emission reduction in my country's coatings industry has also been achieved. After more than 20 years of implementation of the mandatory national standards for limiting harmful substances in the coatings industry, my country's coatings industry has In addition, the limit values of other harmful substances such as formaldehyde, heavy metals, benzene, alkylphenol polyoxyethylene ether, etc. are becoming more and more stringent, and we are actively cooperating with the international It is in line with international standards and points out the direction for comprehensive consideration of environmentally friendly coatings. In order to more scientifically regulate the safety and environmental protection of coating products, promote the development of my country's coating industry towards high quality and sustainable development, In order to enhance the competitiveness of my country's coatings products in the international market, the GB 30981 "Limits of Hazardous Substances in Coatings" series of documents have been integrated and revised. GB 30981 "Limits of Hazardous Substances in Coatings" is planned to consist of two parts. --- Part 1.Architectural coatings. The purpose is to standardize the limit values of harmful substances in various architectural coatings and auxiliary materials. Implementation of test methods, inspection rules, marking and documents. --- Part 2.Industrial coatings. The purpose is to standardize the limit values of harmful substances in various industrial coatings and auxiliary materials. Implementation of test methods, inspection rules, marking and documents. Among them, building waterproof coatings belong to building coatings according to the classification of coating products, but there is already GB 45671 "Safety Technical Specifications for Building Waterproof Coatings" The scope of application of Part 1 of this series of documents will continue to exclude building waterproof coatings. Fire retardant coatings, decorative board coatings The production, construction, performance and application characteristics of three types of coating products, including protective coatings for buildings and structures, are more closely related to industrial coatings. Therefore, these three types of coatings are grouped in Part 2 of this series of documents. Industrial coatings have a wide range of uses. Some coatings have multiple uses. For example, anti-corrosion coatings are used for steel structures such as bridges and for children's play equipment. Compared with architectural coatings, industrial coatings pay more attention to protective properties. The content of harmful substances such as heavy metals is relatively high. In view of the current use of industrial coatings, this revision targets the use of coatings that are in close contact with the human body. More stringent requirements are set for coatings for consumer products, aiming to regulate the use of industrial coatings and better protect the health of consumers. Limits of Hazardous Substances in Paints Part 2.Industrial coatings
