Paint knowledge and development history of fluorocarbon coatings

It is suggested that fluorocarbon coating is a new type of coating which is modified and processed on the basis of fluororesin In 1938, DuPont company of the United States first developed polytetrafluoroethylene, which opened the prelude of fluoropolymer In 1946, polytetrafluoroethylene products began to emerge in the market In 1965, pennwalt company in the United States successfully developed a building fluorocarbon coating based on polyvinylidene fluoride (PVDF) In view of the superior performance of PVDF, people pay more and more attention to the application of ultra long weather resistant anticorrosive coating However, due to the need of high temperature baking, some large-scale Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home news: fluorocarbon coating is a new type of coating based on fluororesin modified and processed The base material is mainly fluoropolymer In 1938, DuPont company of the United States first developed polytetrafluoroethylene, which opened the prelude of fluoropolymer In 1946, polytetrafluoroethylene products began to emerge in the market In 1965, pennwalt company in the United States successfully developed a building fluorocarbon coating based on polyvinylidene fluoride (PVDF) In view of the superior performance of PVDF, people pay more and more attention to the application of ultra long weather resistant anticorrosive coating However, due to the need of high temperature baking, the application of some large facilities, such as building exterior wall, petrochemical, ship, bridge, storage tank and so on, is greatly limited In order to overcome this problem, the subsidiary company of Asahi saltpetre Co., Ltd of Japan took the lead in developing the solvent soluble fluororesin (lumiflon) in the world in 1982 It is made by copolymerization of vinyl fluoride and vinyl ether Compared with PVDF, it has a certain active functional group It overcomes the shortcomings of the original fluorocarbon coating that can not be cured at room temperature It can be crosslinked with other components to achieve the purpose of curing at room temperature It realizes the ideal of coating fluorocarbon coating at the construction site and greatly expands its application field At the same time, the super weatherability of fluorocarbon coating has been further recognized by the market, with high quality On the premise of reasonable construction, the service life of temperature curing fluorocarbon coating can reach more than 20 years, but its price has been in an expensive situation At present, fluorocarbon coating has been applied to the surface of inorganic materials, organic materials, metal materials, enamel products, glass materials, stone materials, etc., such as: high-rise buildings, aircraft skin, cross sea bridges, important port facilities, etc After years of efforts, Shenzhen Mingyuan company has successfully developed its own room temperature curing fluorocarbon coating Its performance is similar to that of foreign products, with obvious performance price advantage Chemical characteristics: fluorocarbon coating is a special or general term for a series of coatings whose base material is mainly fluoropolymer; it is a new coating material modified and processed on the basis of fluororesin Its main feature is that the resin contains a large number of F-C bonds, and its bond energy is 116kcal / mol, which is the first among all chemical bonds (for example, the C-H bond is 99kcal / mol, the C-O bond is 86kcal / mol, and the C-C bond is 83kcal / mol) Therefore, the fluorocarbon coating has far better acid resistance, alkali resistance, weather resistance, corrosion resistance and friction coefficient, oil repellency, water repellency, viscosity resistance, pollution resistance and other excellent properties than the general coating The structure and the activity of fluorine atom of fluorine resin for fluorocarbon coating are very large, which is the most electronegative element among all elements Moreover, each C-C bond in the molecular bond is tightly surrounded by three-dimensional arranged fluorine atoms in spiral form Therefore, the molecular bond is very stable In addition, the volume of fluorine atom is large and has steric hindrance effect Therefore, its stability is the best of all resin coatings This basically determines that it has better performance than other coating materials Bond energy and bond distance: hfcloc bond energy (C-X) [kcal / mol] 98.8105.478.584.083.1 bond distance (C-X) [a] 1.101.361.781.431.50kg electronegativity 2.14.03.03.03.52.5 coating family is focused on coating, diatom mud, paint coating, coating process, news information and coating of fireproof coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fireproof coating,
