Abstract

The invention provides a highly chlorinated polyethylene fireproof coating, which is composed of the following ingredients in parts by mass: 100 parts of highly chlorinated polyethylene, 40-50 parts of fireproof flame retardant, 5-10 parts of acrylic resin, 5-10 parts of titanium dioxide, 15-20 parts of ammonium polyphosphate, 15-20 parts of antimonous oxide, 10-15 parts of pentaerythritol, 10-15 parts of chlorinated paraffin, 10-15 parts of foaming agent, 10-20 parts of xylene, 5-10 parts of reinforcing agent, 10-15 parts of butyl acetate and 5-10 parts of zinc oxide. The highly chlorinated polyethylene fireproof coating product can be dried in 2-3 hours; the highly chlorinated polyethylene fireproof coating has relatively good protection and decoration effects on various substrates; the thickness of the coating film is less than or equal to 3mm and the fire endurance of the coating film is 100 minutes; the highly chlorinated polyethylene fireproof coating has excellent resistance to heat and humidity and is capable of bearing the influence of high and low temperature cycles; besides, the product is excellent in fire resistance and up to the first level national standards; therefore, the coating film is high in adhesion, good in resistance to chemicals, and thus can be widely produced in stead of the existing materials step by step.

Description

technical field [0001] The application belongs to the field of fireproof materials, in particular to a fireproof coating of high chlorinated polyethylene. Background technique [0002] High chlorinated polyethylene is high chlorine content chlorinated polyethylene, also known as HCPE resin. Small white light particles, relative density 1.35-1.45, apparent density 0.4-0.5, chlorine content > 61%, thermal decomposition temperature > 130°C, thermal stability time 180°C > 3mm. Since the molecular structure does not contain double bonds and the chlorine atoms are randomly distributed, it has good weather resistance, ozone resistance, heat aging resistance, flame resistance, chemical resistance and oil resistance. [0003] Due to the regular molecular structure, saturation, low polarity and good chemical stability of chlorinated rubber, various anti-corrosion coatings prepared with it have the characteristics of fast drying of coating film, good adhesion, resistance to c...
