Lightweight thermal insulation gypsum mortar and preparation method thereof

Abstract

The invention provides lightweight thermal insulation gypsum mortar. The lightweight thermal insulation gypsum mortar is prepared from gypsum powder, glass beads, cement, ash calcium powder, mica, silicon dioxide, a water repellent, oyster powder, floating beads, anabaena, polypropylene fibers, a lubricant, a stabilizer, an air entraining agent and a water reducing agent. By adding the glass beads, the thermal insulation performance of the gypsum mortar is improved; through chemical reaction and physical action of the silicon dioxide and the water repellent, the strength and the water resistance of the gypsum mortar are improved; by adopting the oyster powder and the herba houttuyniae, the growth and reproduction of microorganisms can be directly inhibited, so that a bacteriostatic effect is formed, the light gypsum mortar can be prevented from mildewing, and the wall cannot be discolored due to mildewing for a long time.

Description

technical field

[0001] The invention relates to the technical field of gypsum mortar, in particular to a lightweight thermal insulation gypsum mortar and a preparation method thereof. Background technique

[0002] Gypsum is a gel material with a long history. It is listed as the three pillars of meta-mechanical cementitious materials together with lime and cement. As early as 2000-3000 BC, people began to learn to use gypsum and lime. For example, the pyramids of ancient Egypt and many other magnificent buildings were built with gypsum and lime as cementing materials. The use of gypsum materials is of great significance for saving building material resources and improving the technical level of building materials. It usually has the characteristics of light weight, sound insulation, fire resistance, heat insulation, etc., and gypsum is rich in resources, so gypsum is widely used in the field of building materials.
