A kind of fireproof coating added biotite powder

Abstract

The invention discloses a fireproof coating with black mica powder. The fireproof coating with the black mica powder is prepared from the following raw materials in parts by weight: 10-15 parts of black mica powder, 5-8 parts of mullite powder, 8-10 parts of nano-montmorillonite, 3-5 parts of dimethyl phosphate, 10-15 parts of acrylic resin, 15-30 parts of amino resin, 2-4 parts of chlorinated rubber, 2-3 parts of carbamide phosphate, 1-3 parts of silane coupling agent, 5-6 parts of sorbitol, 7-9 parts of aluminium oxide, 3-5 parts of sodium borate, 8-10 parts of vermiculite, 3-4 parts of semi-hydrated gypsum, 3-5 parts of graphite powder, 2-3 parts of titanium dioxide powder, 8-13 parts of organic silicon modified styrene-acrylic emulsion, 5-6 parts of cellulose ether, 2-3 parts of glass powder, 6-8 parts of butyl latex, 2-3 parts of sodium fluosilicate and 3-5 parts of wood fiber. The fireproof coating has the advantages of being excellent in fireproof heat insulation property, excellent in adhesive strength, excellent in water resistance, acid-alkaline resistance and salt corrosion resistance, not easy to fall off, stable in storage, non-toxic and environmental-friendly.

Description

technical field [0001] The invention relates to the technical field of fire-fighting materials, in particular to a fire-proof coating added with biotite powder. 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, good a...
