Abstract

The invention discloses mortar for preparing an EPS decoration component. The mortar is prepared by mixing 42.5 cement, silica sand, cellulose, starch ether, acrylic emulsion and water. The mortar comprises, by mass, 250-400 parts of the 42.5 cement, 600-750 parts of the silica sand, 1-4 parts of the cellulose, 0.2-1 part of the starch ether, 50-150 parts of the acrylic emulsion and 150-250 parts of the water. The mortar has the advantages that the bonding strength of the mortar with EPS base materials is high, and the flexibility of the mortar is good; the EPS decoration component prepared by adopting the mortar has good use performance, construction performance and practical performance, the surface evenness is good, cracking, blistering and pitted surfaces do not occur, and the mortar can stick to the EPS base materials to form an ideal whole.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a mortar used for preparing EPS decoration components. Background technique [0002] With the rapid development of my country's construction industry, prefabricated buildings and building energy conservation have received widespread attention. This has promoted the research and application of various types of building prefabricated components. Compared with the main structure that plays a supporting role, the prefabricated components that play a decorative role do not need to have strong support strength. At present, they are mainly based on EPS materials. Components, by wrapping self-adhesive mesh and coating mortar on the basic components to form a decorative prefabricated component, which has the characteristics of light weight and convenient installation. However, at present, in the production and preparation process of decorative components based on EPS in this field, ordin...
