Problems solved by technology

However, most of the existing plastering mortars stick the sand together through the cohesiveness of the cement, and the performance characteristics of the cement itself are high hardness and high brittleness, resulting in poor tensile strength of the mortar, not durable, easy to crack, and heat insulation. and poor sound insulation

Abstract

The invention belongs to the technical field of building materials, and relates to a novel coating for building wall surfaces. The novel coating is composed of the following components in percentage by mass: 25-35% of silicon dioxide fiber, 30-50% of perlite micro powder, 10-20% of hollow glass beads and 20-30% of sericite powder. The coating replaces cement mortar to be smeared on the surface of a building, so that the wall surface is flat and smooth, the coating property is stable, and the heat insulation and sound insulation effects are good.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a novel paint for building walls and its preparation method and application. Background technique [0002] At present, buildings are mainly constructed of concrete and brick walls. This kind of material absorbs light in a range of light, stores a large amount of heat, and dissipates heat slowly, which leads to a rapid rise in temperature inside the building and a long duration of high temperature. Plastering refers to the project of mixing dry mortar powder and water according to a certain water-cement ratio to form mortar and then evenly applying it on the surface of the building. Commonly used plastering mortars are lime mortar, mixed mortar, cement mortar and polymer cement mortar. After the above mortar is applied, a coating film with a thickness of about 20mm can be formed on the surface of the building, making the surface of the building smooth and mo...
