Problems solved by technology

[0002] At present, the construction industry uses paint or paint coating on the interior walls of buildings as a decorative surface layer, which generally has defects such as cracking, falling off, easy corrosion by water, mildew, easy dirt after absorbing dust, easy fading under long-term light, and short service life; In wet weather, the wall surface will return to moisture and even condense water droplets. In addition, the existing plaster has poor thermal insulation performance, is easy to fall off, and has poor bonding force with the wall. The existing wall construction method has poor construction stability, safety and reliability. Poor performance, poor durability and other defects, can not meet the construction needs

Abstract

Provided is a moisture proof wall construction method. The method comprises the steps of adding ethylene glycol diacrylate, hydroxyethyl methacrylate, 2,4,6-trimethylbenzoyl diphenylphosphine oxide and polyvinyl alcohol to a chemical kettle, stirring evenly, pressurizing to 0.2-0.3MPa, keeping pressure for 1.5-2 hours, and obtaining a composite mother liquor; an interface agent is added with microsilica powder, silane capping polyether, phenyl sulfonate and a phenyl maleimide-based silicone resin to improve the bonding strength between the interface agent and a wall, the interface agent bearsthe load acting on the wall, the interface agent also has good impermeability, and has good bonding effect with a plastering mortar, the overall strength and moisture resistance of the wall are increased, the fluidity is good, and convenience is provided for construction.

Description

technical field [0001] The invention relates to a moisture-proof wall construction method, which belongs to the field of wall construction. Background technique [0002] At present, the construction industry uses paint or paint coating on the interior walls of buildings as a decorative surface layer, which generally has defects such as cracking, falling off, easy corrosion by water, mildew, easy dirt after absorbing dust, easy fading under long-term light, and short service life; In wet weather, the wall surface will return to moisture and even condense water droplets. In addition, the existing plaster has poor thermal insulation performance, is easy to fall off, and has poor bonding force with the wall. The existing wall construction method has poor construction stability, safety and reliability. Poor performance, poor durability and other defects cannot meet the construction requirements. Therefore, a new technical solution should be provided to solve the above problems. ...
