General knowledge of coating: application performance of epoxy fire retardant coating

The core tip: at present, some active components of the intumescent fire retardant coating used in our country will slowly separate out under the wet condition, which affects the fire protection effect However, epoxy resin has no similar problems due to its excellent sealing property It is the key to insist on the durability and weatherability of fire retardant coating to prevent the active components from precipitation Outdoor fire-retardant coating should be mainly epoxy paint, the reason is that epoxy paint has better corrosion resistance and light weight In addition, because of its excellent impact strength, adhesion and moisture resistance, it can also be used in some indoor places such as swimming pools, baths and high-rise buildings 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 of coatings news: at present, some active components of the intumescent fire retardant coating used in China will slowly separate out under wet conditions, affecting the fire protection effect However, epoxy resin has no similar problems due to its excellent sealing property It is the key to insist on the durability and weatherability of fire retardant coating to prevent the active components from precipitation Outdoor fire-retardant coating should be mainly epoxy paint, the reason is that epoxy paint has better corrosion resistance and light weight In addition, because of its excellent impact strength, adhesion and moisture resistance, it can also be used in some indoor places such as swimming pools, baths and high-rise buildings The advantages of epoxy fire-retardant paint compared with domestic general fire-retardant paint are shown in two aspects: first, epoxy resin has a strong sealing performance and can be widely used outdoors Second, epoxy resin is a thermosetting resin, which has the function of resisting hydrocarbon fire A new type of outdoor fire-retardant coating epoxy fire-retardant paint has replaced thick fire-retardant paint The lack of suitable outdoor fire-retardant paint has become a major problem in the domestic paint industry But abroad Structures with hydrocarbon fire hazards, marine facilities, petrochemical and petroleum units and offshore oil platforms have been widely used Epoxy resin has good adhesion to most materials such as wood, metal, glass, plastic, rubber, leather, ceramics, fiber, etc The cured epoxy resin contains aliphatic hydroxyl group, ether group and active epoxy group It has excellent chemical corrosion resistance, heat resistance, acid and alkali resistance and good electrical insulation The fire-proof paint prepared with it has good adhesion, corrosion resistance and mechanical strength Epoxy fire-retardant paint also has excellent sealing performance, and the flame-retardant components will not migrate to the coating surface, so its fire-retardant performance is less affected by time and environment Especially after the explosion, the epoxy resin fire retardant coating can adhere to the good condition and adhere to the base material, which is more suitable for offshore oil platforms, oil fields, refineries and petrochemical plants than the radical expansion fire retardant paint Another important reason for choosing epoxy resin as film forming agent is that epoxy resin can be used as carbon forming agent of intumescent fire-retardant paint Radical theory holds that the charring agent is the material basis for the formation of a non flammable foam carbonized layer, and plays a skeleton role in the carbonization layer of the foam, and some polyhydroxyl compounds containing high carbon A large number of experiments have proved that epoxy resin can be used as a carbon forming agent, and can react with dehydration catalyst to form porous carbonized layer 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,
