Research and Development Prospect Analysis of Environmentally friendly Coatings

introduction
The coating industry has a very long history in the development of the national economy and infrastructure, which provides a basic guarantee for the development of various undertakings in China. However, with the gradual increase of the country's attention to environmental pollution, traditional solvent-based coatings have been unable to meet the development goal of "environment-friendly society", and the development of environmentally friendly coatings is imminent. Due to the current high R&D cost and production cost of environmentally friendly coatings, it has encountered obstacles in the market, and the R&D and production of low-priced, high-performance environmentally friendly coatings to replace traditional solvent-based coatings has become a problem that large coating companies must face.

1 Research significance of environmentally friendly coatings With the rapid development of industrial society, large-scale industrial construction has brought huge economic benefits to people. However, as the problem of environmental pollution becomes more and more serious, environmental protection has become the most basic task of all countries. White pollution, water pollution, air pollution, light pollution, and indiscriminate felling of trees and many other pollution problems closely related to human life can no longer be ignored. However, in the face of fierce competition in the market economy, interests and the environment have become two opposing factors, and some enterprises are facing huge profit temptations in exchange for economic benefits at the cost of polluting the environment. In today's world, the environmentally friendly coating industry is still in an emerging stage of development, and countries around the world are actively developing new environmentally friendly coating products. Because solvent-based coating products have greater pollution in the production process, and at the same time produce greater harm to the health of workers, and volatilize a large number of toxic gases in the process of use, which also has a huge harm to the health of users. The latest R&D achievements of various countries have initially solved serious problems such as high pollution and high toxicity, but due to the high production cost and insufficient purchasing power of the purchasing group, environmentally friendly coating products were once in the unsalable stage. Therefore, the development and production of cheap and environmentally friendly coatings has become a higher goal for the innovative research and development of coating enterprises. Because of this, the development of environmentally friendly materials and the replacement of existing materials with high pollution or production of highly polluting materials have become a focus of today's society. The successful development of environmentally friendly materials not only brings greater economic benefits to the society, but also solves the contradictory relationship between the economic benefits of high-polluting enterprises and environmental protection, and at the same time makes the best solution to the problem of environmental pollution. This paper takes the development of environmentally friendly coatings as the research object and discusses the future development of China's environmental protection coatings.

2 Research and development status of environmentally friendly coatings At present, China's environmentally friendly coatings are in a stage of rapid development, and the commercially available environmentally friendly coatings mainly include: water-based coatings, powder coatings, solvent-free coatings, high-solid coatings, light-curing coatings, etc.
