Description
[01] The present disclosure relates to the technical field of coating diluents, in particular to a coating diluent containing a solvent not participating in a photochemical reaction, and a preparation method and use thereof.
[02] A coating diluent contains a variety of solvents. The coating diluent is mainly used to adjust the viscosity of a coating, such that the coating can be suitable for different coating methods, such as brushing, spraying or dipping. The coating diluent is an indispensable product in the coating industry. China has the largest coating output in the world, and coating diluents have a large market, with an annual output of at least 5 million tons.
[03] Solvents in coatings will cause many effects on the environment. During coating production, construction, and use, the released solvents and toxic substances cause serious pollution to the environment. According to the government regulations of the United States, volatile organic compounds (VOC) are limited to those compounds that are photochemically active in the atmosphere, and any other compounds are defined as exempted compounds. Exempted compounds are defined in IS011890-1: 2007 "Paints and varnishes - Determination of volatile organic compound (VOC) content - Part 1: Difference method": organic compounds that do not participate in photochemical reactions in the atmosphere.
[04] China is now paying more and more attention to the protection of the environment and human health. Many environmental protection laws and regulations in line with international standards have been established, to promote the development of low-toxicity or even non-toxicity solvents, and solvents that do not participate in atmospheric photochemical reactions are used.
[05] Therefore, the preparation of a low-toxic or even non-toxic coating diluent containing a solvent not participating in a photochemical reaction has a very broad market prospect.
[06] The purpose of the present disclosure is to provide a coating diluent containing a solvent not participating in a photochemical reaction. The coating diluent addresses the defects of the release of solvents and toxic substances during the production and use of a coating in the prior art.
