Coating classification: perchloroethylene coating

Core tip: Introduction: perchloroethylene coating refers to the volatile coating with perchloroethylene resin as the main film-forming material and other synthetic resins, pigments, plasticizers and organic solvents, which can be used for anticorrosion and decoration coatings of machine tools, aviation, vehicles, chemical pipelines and equipment, as well as fire retardant coatings of wood and fiber products Perchloroethylene resin is made of PVC resin by chlorination It belongs to thermoplastic resin and can be dissolved by ketone, ester and other solvents to form volatile paint Compared with vinyl chloride resin, perchloroethylene resin has saturated structure, few side groups, more chlorine atoms, and chlorine content of 64% - 65% 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 Brief introduction: perchloroethylene coating refers to the volatile coating with perchloroethylene resin as the main film-forming material and other synthetic resins, pigments, plasticizers and organic solvents, which can be used for anticorrosion and decorative coating of machine tools, aviation, vehicles, chemical pipelines and equipment, as well as fire retardant coating of wood and fiber products Perchloroethylene resin is made of PVC resin by chlorination It belongs to thermoplastic resin and can be dissolved by ketone, ester and other solvents to form volatile paint Compared with vinyl chloride resin, perchloroethylene resin has saturated structure, few side groups and more chlorine atoms The content of chlorine can reach 64% - 65% Its polarity is enhanced, and it can form a compact corrosion-resistant coating It not only has excellent corrosion resistance, non flame retardance, electrical insulation and mildew resistance, but also can be dissolved into a solution with low viscosity and high concentration in many solvents, forming a favorable coating production Its disadvantage is that it can't be used to prepare coating alone The coating only made of perchloroethylene resin has poor adhesion, incomplete film and poor gloss The main varieties of perchloroethylene paint are iron red perchloroethylene primer, various colors of perchloroethylene putty, various colors of perchloroethylene external enamel, various colors of perchloroethylene anticorrosive paint, perchloroethylene anticorrosive varnish, etc Features: the characteristics of perchloroethylene are as follows: ① fast drying, light color ② Good chemical resistance is one of the biggest advantages At room temperature, it hardly corrodes in 25% sulfuric acid, nitric acid and 40% sodium hydroxide solution for several months, even for more than two years; it is also stable in most of the media such as salt, water, sea water, alcohol, lubricating oil, oxygen, ozone, etc However, it is not stable for glacial acetic acid, aqua regia, nitric acid mixed with water content less than 20%, nitric acid more than 90% and more organic compounds ③ The film is almost intact after exposed to the atmosphere for one year ④ The three prevention function is very good and can be extinguished after the fire source is evacuated ⑤ Good fire performance can be extinguished after the fire source is evacuated ⑥ Good cold resistance can keep the mechanical properties in cold area, not easy to crack ⑦ Poor heat resistance can not be used at high temperature, generally under the condition of less than 60 ℃ When the temperature is higher than 145 ℃, the paint film decomposes, cracking becomes brittle and the color becomes dark ⑧ The slow release of solvent perchloroethylene has the characteristics of solvent retention The coating film is easy to surface dry, and the complete drying speed is slow It can be dried in 2 hours under normal temperature The real performance of the coating film can be achieved only when the film is completely dry ⑨ The adhesion of perchloroethylene resin coating is poor It needs to add modifier, such as alkyd resin or other synthetic resin, and retain the advantages of perchloroethylene coating Other synthetic resins can not only enhance the adhesion of the film, but also improve its luster, fullness and outdoor weather resistance The commonly used resins are rosin modified phenolic resin, rosin modified maleic anhydride resin, alkyd resin, acrylic resin, etc Perchloroethylene coating is generally multi-layer spraying, and the paint film is easy to repair and maintain The solvents used in perchloroethylene coating are usually mixed with ester (such as ethyl acetate), ketone (such as acetone) and benzene (such as toluene) Do not use alcohol solvent or nitrocellulose coating diluent 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,
