Problems solved by technology

[0002] The existing traditional cement mortar is prone to problems such as hollowing and cracking, and the bulk density is relatively large, which increases the overall building weight. This invention solves the above-mentioned shortcomings of cement and increases the thermal insulation and fire resistance of the system

Abstract

The invention discloses inner wall light thermal insulation mortar, which consists of the following components in part by weight: 1,000 parts of mixture of gypsum powder and stone powder No.70 sand, 200 to 600 parts of vitrified micro bubbles, 0.3 to 5 parts of cellulose, 1 to 10 parts of inorganic gel and 0.5 to 5 parts of retarder. The phenomena of hollowness and cracking are avoided; the volume weight of the product is 60 percent of that of the traditional mortar; the overall weight of a building is greatly reduced; and the vitrified micro bubbles added into the inner wall light thermal insulation mortar have high thermal insulation property and fire-resisting property, so that the thermal insulation property and fire-resisting property of the building are greatly improved.

Description
