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

The invention discloses a construction method for a damp-proof wall. The construction method comprises the following steps that ethylene glycol diacrylate, hydroxyethyl methylacrylate, 2, 4, 6-trimethylbenzoyl-diphenyl phosphine oxide and polyvinyl alcohol are added into a chemical industry kettle to be stirred evenly, the pressure is increased to 0.2-0.3 MPa and kept for 1.5-2 h, and a compound mother solution is obtained. According to an interface agent provided by the invention, the bonding strength of the interface agent and the wall is improved by adding silica fume, silane end-capping polyether, alkyl sulfonic acid phenyl ester and phenyl maleimide group silicone resin. The interface agent bears the load acted on the wall, meanwhile the interface agent has good anti-permeability and has good bonding effect with plastering mortar, the overall strength and moisture-proof performance of the wall are improved, and the interface agent has good fluidity and is convenient for construction.

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. ...
