Encyclopedia of coatings: Research on the chemistry of two coatings

Although the development of polymer science is the most important foundation of paint science, polymer science alone cannot make paint an independent science Coatings need not only polymers, but also inorganic and organic pigments, additives and solvents to achieve various properties In order to prepare a stable and suitable coating and obtain the best application effect, the theoretical guidance of colloidal chemistry, rheology and optics is also needed Therefore, coating science is a new subject based on polymer science, organic chemistry, inorganic chemistry, colloidal chemistry, surface chemistry and surface physics, rheology, mechanics, optics and color science Because coating science involves so many theories, it cannot develop into a subject for a long time Of course, coating is not a simple combination of various related disciplines, but an independent discipline with its own characteristics established on the basis of them, including coating theory, surface structure and performance, coating technology, various analysis and testing methods and theories, as well as relevant theories of various applied products Since the 1980s, energy, materials and environment have become three major topics with the characteristics of the times Coating is an important means to protect materials, and it is also the easiest way to modify various materials to give new properties A large number of solvents are used in coatings, which are important sources of air pollution Therefore, the development of low pollution coatings is the need of environmental protection On the other hand, due to the protection of coatings, the environmental pollution caused by material damage is reduced Coatings are also important materials for beautifying the environment Naturally, the use of paint also has a certain relationship with energy Now, coating has a close relationship with the development of national economy, the improvement of people's living standards, the development of national high-tech and military technology It can be said that the level of coating industry is one of the symbols of national modernization.
