Paint knowledge | development history of wood paint

Core tip: the history of human production and use of paint can be traced back to the stone age A large number of archaeological data have proved that in the primitive society 7000 years ago, human beings have used the fat, tree juice and natural pigments of wild animals to make up the original painting materials, and used feathers, branches and other paintings to achieve the purpose of decoration With the progress of human society, after entering the bronze age, the ancient civilization has made different progress in directly using natural materials to prepare coatings As early as the Shang Dynasty, China had taken down natural lacquer ornaments, palaces and temples from wild lacquer trees By the spring and Autumn period, the refining system of tung oil had been mastered Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: the history of human production and use of paint can be traced back to the stone age A large number of archaeological data have proved that in the primitive society 7000 years ago, human beings have used the fat, tree juice and natural pigments of wild animals to make up the original painting materials, and used feathers, branches and other paintings to achieve the purpose of decoration With the progress of human society, after entering the bronze age, the ancient civilization has made different progress in directly using natural materials to prepare coatings As early as the Shang Dynasty, China had taken down natural lacquer ornaments, palaces and temples from wild lacquer trees By the spring and Autumn period, we had mastered the technology of refining tung oil to make coatings In the Warring States period, we had been able to use raw lacquer and tung oil compound coatings, which created the technology of using additives in coatings, and promoted the development of coatings to a new era The lacquered coffins and lacquerware unearthed from Mawangdui Han tomb in Changsha have tough film and excellent protection performance, which fully shows the maturity of Chinese lacquer technology in the 2nd century BC As a result of the application of tung oil and lacquer, the customary term "paint" has been spread to this day In the last century, the great achievements of polymer science theory and the successful development of various polymer compounds have been put into production, creating a new era for the development of paint In the 1920s, alkyd resin, which is specially used as film-forming material for coatings, was developed successfully Since then, various newly developed synthetic resins have been applied in coatings rapidly, making coatings enter the era of film-forming material mainly In 1980, the annual output of coatings in the world exceeded 20 million tons, and the annual per capita consumption of coatings in developed countries reached more than 10kg Modern coating industry has become an important industry in modern chemical industry Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
