Abstract

The invention relates to moisture-proof wall spraying slurry which comprises the main composition raw materials: polyether-based anti-hydrolysis polyurethane resin, liquid organopolysiloxane, 1,1'-azobis(cyclohexane-1-carbonitrile), expanded vermiculite, thermal expansion microcapsules, methyl tetrahydrophthalic anhydride, hexadecylsulfonic acid sodium salt, vegetable gelatin, alumina powder, modified lignocelluloses, a silane coupling agent, diatomaceous earth, an efficient micropore agent, nano-silica, titanium dioxide, phenyl salicylate and tetrahydrofuran. The prepared slurry is strong in tenacity, good in moisture resistance, excellent in ageing resistance, bright in appearance color, and high in flatness and uniformity.

Description

technical field [0001] The invention relates to a moisture-proof wall surface spray coating slurry. Background technique [0002] In today's construction field, there are mainly two ways to decorate the interior and exterior walls of buildings, that is, coating paint or paint and pasting tiles and stones. The former generally has poor moisture resistance and is prone to problems such as cracking, falling off, fading, and mildew. The latter has high construction costs, long paving and pasting operation cycle, difficult to control the flatness, easy to fall off the brick body, and prone to water seepage. Therefore, wall surface spraying treatment is a new type of wall surface treatment method, which has the advantages of simple and fast construction, and easy control of surface flatness and uniformity. However, the wall spraying pastes currently on the market still have obvious deficiencies in terms of moisture permeability, wear resistance and aging resistance. Contents o...
