Abstract

The invention discloses a fluororesin modified high-chlorinated polyethylene fireproof anticorrosion composite coating, which is composed of two components A and B, wherein the component A is prepared from polyvinylidene fluoride glue solution, ammonium polyphosphate, modified high-chlorinated polyethylene resin, pentaerythritol, melamine, titanium dioxide, zinc oxide, fluoroferrophosphorus, nanosilicon dioxide, carboxylic polymer, fluorocarbon modified polysiloxane, miscella, butyl acetate, chlorcosane and the like; and the component B is prepared from isocyanate and ethyl acetate; the fluororesin modified high-chlorinated polyethylene fireproof anticorrosion composite coating is prepared from the component A and the component B in the weight ratio of 100.0:(9.0-11.0); the fluororesin modified high-chlorinated polyethylene fireproof anticorrosion composite coating is called as FFFH fireproof anticorrosion coating for short; the coating has the characteristics of high strength, low specific weight, outstanding corrosion resistance and fire resistance, and the like. The fluororesin modified high-chlorinated polyethylene fireproof anticorrosion composite coating can be widely applied to industries such as chemical industry and food, and has excellent economic and social benefits.

Description

1. Technical field [0001] The invention belongs to the field of industrial anti-corrosion, and is a two-component solvent-based fluororesin modified high-chlorinated polyethylene coating, which has dual functions of anti-corrosion and fire prevention, referred to as FVC fire-proof and anti-corrosion composite coating. 2. Technical background [0002] At present, there are many kinds of corrosion-resistant coatings on the market in our country, each with its own characteristics, but the anti-corrosion ability of fire-resistant coatings is poor, and corrosion-resistant coatings do not have fire-proof functions, so that projects that require dual functions of fire protection and corrosion protection must sometimes choose both anti-corrosion and fire protection. The combination of the two coatings will lead to an increase in the construction period and an increase in the project cost. Sometimes the combination of the two coatings is not ideal and the service life of the coating w...
