The development of wood paint

The development of wood
the history of human production and use of paint can be traced back to the Stone Age. From the discovery of a large number of archaeological data confirmed that in the primitive society 7,000 years ago, humans have used wild animal grease, tree juice and natural pigments, such as the preparation of the original decorative materials, with feathers, branches and other paintings, in order to achieve decorative purposes. With the progress of human society, after entering the Bronze Age, the ancient civilizations of the time made different progress in the direct use of natural materials to make coatings
China
. As early as the Shang Dynasty, China has removed natural lacquer ornaments from wild lacquer trees, as well as palaces and temples. By the spring and autumn era has mastered the technology of refining oil coatings, the War Years has been able to use raw paint and oil compound coatings, creating the use of additives in coatings technology, to promote the development of coatings to a new era. The lacquer coffins and lacquer coatings unearthed from the tomb of Wang Hehan in Changshama are tough and have excellent protection performance, which fully demonstrates the maturity of the development of raw paint technology in China in the 2nd century BC. Due to the application of oil and large paint and formed a "paint" customary title, has been circulating to this day.
the last century, the major achievements of polymer science theory and the successful development of various polymer compounds into production, for the development of paint to create a new era. In the 1920s, the development of a specifically used as a coating film-forming substance alicic acid resin, from then on a variety of newly developed synthetic resins in the paint quickly be applied, so that the coating into the synthetic film-based material-based era. In 1980, the world's annual production of coatings more than 20 million tons, developed countries, the annual per capita consumption of coatings reached more than 10 kg, modern coatings industry has become an important industry of modern science and technology industry.
China's annual per capita consumption of paint is only one-fifth of that of developed countries, but with the development and promotion of the industry, the advantages of coatings have been more and more people understand, so in the future, China's paint industry prospects are very broad.
