Abstract

The invention provides a sand textured two-component plaster mortar composition. The composition consists of the following components in parts by weight: 20 to 30 parts of white cement, 40 to 60 parts of silicon carbide, 0.5 to 1.5 parts of gelatin powder, 0.1 to 0.3 part of xanthan gum, 0.1 to 0.2 part of cellulose ether, 3 to 7 parts of lithopone, 1.5 to 3 parts of fire retardant, 0.1 to 0.5 part of sodium tripolyphosphate, 0.1 to 0.5 part of hardening agent, 0.1 to 0.3 part of defoaming agent, 40 to 50 parts of modified polyurethane emulsion, and 1 to 3 parts of dipropylene glycol methyl ether. A filmed polyurethane adhesive film has hydrophobic nature better than an adhesive film copolymerized from pure acrylic acid, styrene-acrylate or vinyl acetate, so that the mortar spraying effect is excellent, and the effect of simulating stones rivals that of stones; and the composition has good effects in adhesive strength, water resistance, stain resistance, light and weather resistance.

Description

technical field [0001] The invention relates to a construction mortar. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, the development of modern high-end residential buildings, commercial buildings, and new public building facilities in China has entered a new period. People pay more attention to beautifying the environment while meeting material needs. The requirements of high-end residential buildings, commercial buildings, and new public buildings put forward higher requirements for aesthetics, high quality, and environmental protection. Sand wall-like mortar is a new type of exterior material because of its simulated stone effect and Reliable quality, convenient operation and economic benefits have been valued. However, the sand wall-like coatings currently used in the market, the adhesives are mainly polymer resins or emulsions such as pure acrylic, styrene-acrylic or vinyl acet...
