Abstract

The invention provides a hydrocarbon resistance fire-proof and explosion-proof coating which is prepared from, by weight, 20-60 parts of emulsion powder, 0-20 parts of polyvinyl alcohol, 1-3 parts of hydrogenated castor oil, 15-35 parts of polyvalent alcohol phosphate flame retardant, 5-13 parts of melamine cyanurate, 4-16 parts of zinc borate, 3-6 parts of modified expanded vermiculite and 0-2 parts of rutile type nanometer titania. The coating is high in hydrocarbon fire resistance limit, also has the explosion resistance, can adhere to a base material in the good condition after an explosion happens, enables a coating film to have the pressure relief function in the explosion, and is good in adhesion force, high in strength, capable of withstanding influences of high and low temperature cycling, good in water resistance, acid-base resistance, salt corrosion resistance and weather resistance, good in flexibility, not prone to disengagement, stable in storage, long in service life, environmentally friendly, convenient to construct, low in construction cost, simple in preparation technology and low in energy consumption. The hydrocarbon resistance fire-proof and explosion-proof coating is particularly suitable for being used as surface coatings of steel materials, aluminum materials and other materials in indoor and outdoor petrochemical industries.

Description

Technical field: [0001] The invention relates to a fireproof and explosion-proof coating, in particular to a hydrocarbon-resistant fireproof and explosion-proof coating. Background technique: [0002] Most of the fires in petrochemical enterprises are typical hydrocarbon fires. Hydrocarbon fires generally heat up faster and have more violent flames than cellulose fires. In hydrocarbon fires, the effectiveness of conventional fire protection coatings designed for cellulosic fires is only about 60% in hydrocarbon fires, and when hydrocarbon fires occur, explosions are often accompanied. Chinese patent 200610091048.3 discloses a solvent-free intumescent fireproof coating, which is composed of two components A and B. The component A uses epoxy resin as the main film-forming substance, and adds modified resin, catalyst, char-forming agent, and foaming agent. , flame retardant, flux, pigment and filler, smoke suppressant, component B is composed of pigment and filler, curing agen...
