Problems solved by technology

[0002] At present, there are many kinds of putty for exterior walls, mainly used for cement walls and concrete walls, with different strengths. When putty for exterior walls is used for renovation of some tile walls and mosaic walls, the putty has weak adhesion and water resistance. Poor and other defects, but also the problem of low fire protection level, in the prior art, the fire resistance of putty materials is usually improved by adding fire protection ingredients, but when fire protection materials are added, its heat preservation, waterproof, strength and moisture absorption rate will be lower. effect, therefore, further research on fireproof putty powder is needed to improve

Abstract

The invention specifically relates to a processing method capable of improving the heat retaining property of fireproof exterior wall putty, belonging to the field of processing technology for fireproof exterior wall putty. The fireproof exterior wall putty is prepared by mixing dry powder raw materials, clear water and a diluted styrene-butadiene emulsion, wherein the dry powder raw materials arecomposed of concrete, phenolic epoxy compounds, wollastonite, sodium sulfate decahydrate, borax, magnesia, boron chloride, calcined china clay, aromatic six-functional urethane acrylate, a phase separation inhibitor and a composite additive. Compared with the prior art, the invention has the following advantages: the putty prepared in the invention is environment-friendly, durable, firm, highly efficient, crack-proof, time-saving and labor-saving, and shows good tensile adhesive strength; a prepared reaction material has heat preservation and energy storage performance; and the putty is applicable to leveling and repairing of a variety of crack-vulnerable bases like external wall insulation layers and cement mortar, prevents cracks on surface base layers, and has good resistance to weather, fire, external stress, storage and transport.
