General knowledge of coating: anticorrosive effect of glass flake coating and chlorinated rubber coating

Core tip: glass flake coating and chlorinated rubber coating are one kind of anticorrosive coating W2-1 vinyl ester resin glass flake coating has been developed by equipment Research Institute of Changling Oil Refining and Chemical Co., Ltd It has been applied to the anticorrosion of the storage tank of the acid water system of the alkali residue treatment unit in the sulfur making workshop, and has solved the old and difficult problems that have puzzled for many years After nearly two years of application, satisfactory results have been achieved W2-1 vinyl ester resin is produced by Shanghai Huachang polymer company Its structure and properties are equivalent to that of Dow Chemical Company of the United States 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 Coating home news: glass flake coating and chlorinated rubber coating is a kind of anticorrosive coating W2-1 vinyl ester resin glass flake coating has been developed by equipment Research Institute of Changling Oil Refining and Chemical Co., Ltd It has been applied to the anticorrosion of the storage tank of the acid water system of the alkali residue treatment unit in the sulfur making workshop, and has solved the old and difficult problems that have puzzled for many years After nearly two years of application, satisfactory results have been achieved W2-1 vinyl ester resin is produced by Shanghai Huachang polymer company Its structure and properties are equivalent to derakane-470 resin of American Dow Chemical Company This kind of resin has the advantages of epoxy phenolic composite resin and unsaturated polyester resin, that is, it has the excellent mechanical properties of epoxy phenolic composite resin and the simple molding performance of unsaturated polyester resin at room temperature W2-1 vinyl ester resin has excellent acid and alkali corrosion resistance It can be used for a long time under phenol content of 1% ~ 2% and temperature of 85 ℃ Therefore, it can meet the anti-corrosion requirements of acid water system At the same time, according to the anti-corrosion and anti-seepage mechanism of glass flake coating, adding glass flake can significantly improve the anti-corrosion and anti-seepage ability of the coating lining when the resin is selected properly, and its performance is superior to that of glass fiber reinforced plastic This kind of resin has good water, acid, alkali corrosion resistance and oxidation resistance W2-1 vinyl ester resin quality index, physical properties, corrosion resistance Glass flake coating can use many kinds of base materials, but most of them are still various kinds of unsaturated polyester resin with additional initiator In the last 20 years, epoxy system with curing agent has become an important part of glass flake coating The properties of glass flake coating with different base materials are different Epoxy resin series and polyurethane series have been produced and applied in China Among them, there are 8830 epoxy resin series glass flake heavy-duty anticorrosive coating, 8850 epoxy asphalt series glass flake heavy-duty anticorrosive coating and Beijing h04-15 epoxy asphalt glass flake coating As for chlorinated rubber coating, due to its saturated molecular structure and no active chemical group, it has good weather resistance and chemical stability, certain corrosion resistance to acid and alkali, low water vapor permeability, good water resistance, brine resistance and salt fog resistance It can be used in combination with zinc rich paint, with long-term corrosion resistance, and can be made into thick film coating Carbon tetrachloride used in the manufacture of chlorinated rubber will destroy the ozone layer and be toxic, so it has become a restricted object At home and abroad, high chlorinated polyethylene and acrylate rubber are being used as substitute products of chlorinated rubber According to the performance price ratio, the existing hull paint is divided into acrylic polyurethane, acrylic acid, fluororesin, silicone modified alkyd, high vinyl chloride, chlorinated rubber and alkyd In the above-mentioned hull paint, due to the release of a large number of harmful gases to human body and the environment during the production of chlorinated rubber, some developed countries have no longer produced the resin, which will be replaced by high vinyl chloride and polyether resins that do not pollute the environment In the structure of coating products, the anticorrosive industrial coating is paid more attention at present Among the anti-corrosion coatings, the most prominent ones are heavy-duty coatings, especially marine coatings (it is predicted that as the third largest shipbuilding country in the world, the demand for marine coatings will increase by 30% every year), container coatings, automobile and construction industrial coatings In addition to the above development direction, for special occasions and special needs, such as the need for high temperature resistance, radiation resistance and other properties of heavy-duty anti-corrosion coating research and development is still the future development direction In recent years, in developed countries, heavy-duty coating products and production have accounted for about 7% of the coating market It is estimated that the production of anticorrosive coating in China has reached 280kt in recent years, among which phenolic anticorrosive coating and alkyd anticorrosive coating with low price are still widely used in general anticorrosive coating, while the supporting system of heavy anticorrosive coating has been greatly developed in recent years In China, there are about 10K tons of epoxy zinc rich and inorganic zinc rich coatings, 60K tons of epoxy anticorrosive coatings, 10K tons of polyurethane coatings (for anticorrosive engineering), 30K tons of ethylene anticorrosive coatings and 15K tons of powder anticorrosive coatings In the anticorrosive coating system, epoxy coating and polyurethane coating are the main force of heavy anticorrosive coating, which have great development prospects Home of
