A kind of fireproof coating with added calcium sulfate whiskers

Abstract

The invention discloses a calcium sulfate whisker added fireproof coating material. The calcium sulfate whisker added fireproof coating material is prepared from the following raw materials in parts by weight: 8-12 parts of calcium sulfate whiskers, 5-8 parts of talcum powder, 10-12 parts of bentonite, 5-8 parts of pearlite, 3-5 parts of dimethyl phosphate, 10-15 parts of acrylic resin, 15-20 parts of epichlorohydrin resin, 2-4 parts of chlorinated rubber, 3-4 parts of ammonium polyphosphate, 1-3 parts of titanate coupling agent, 5-6 parts of pentaerythritol, 2-4 parts of starch, 3-4 parts of hydrogenated castor oil, 2-3 parts of glass powder, 3-4 parts of zinc borate, 1-3 parts of ferrocene, 6-8 parts of butyl latex, 2-3 parts of sodium fluosilicate, 3-6 parts of carbon black and 3-5 parts of wood fiber. The fireproof coating material disclosed by the invention has the advantages of good fireproofing and heat insulating properties, good adhesion, water resistance, acid / alkali resistance, good salt corrosion resistance, difficulty in shedding, stability in storage, no toxicity, environmental friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of fire-fighting materials, in particular to a fire-proof paint added with calcium sulfate whiskers. Background technique [0002] At present, fire retardant coatings are more and more widely used in petrochemical, electric power, industrial and civil construction, machinery and other industries. Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. However, the existing fireproof coatings have the problems of difficult balance of coating film surface adhesion, moisture resistance, water resistance, frost resistance and flame retardancy. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a fireproof and heat insulation performance...
