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 damp-proof wall. A construction method of the damp-proof wall includes the steps: dispensing 150-180 parts of gypsum, 30-50 parts of hollow glass beads, 10-20 parts of ceramsite, 20-30 parts of mica powder, 10-20 parts of silica sol, 10-20 parts of cement, 5-10 parts of sodium silicate, 3-5 parts of dibutyl phthalate, 1-4 parts of sodium pentachlorophenate and 40-70 partsof water; placing the mica powder into a pulverizing mill for pulverizing for 30-60 minutes and enabling average particle size to reach 0.05-0.1mm; uniformly mixing the pulverized mica powder, the hollow glass beads and the ceramsite. By the aid of the hollow glass beads, the ceramsite and the mica powder of plastering mortar, the wall has a better heat retaining property, bonding strength between the mortar and an interface agent is improved by adding the sodium silicate, the dibutyl phthalate and the sodium pentachlorophenate, and the compression and shear bond strength of the wall is greatly improved.
