Abstract

The invention discloses interior wall thermal insulation putty and a preparation method. The interior wall thermal insulation putty is prepared from, by mass, 20-30% of light calcium carbonate powder,15-20% of floating beads, 10-15% of titanium dioxide, 25-30% of shell powder, 3-5% of nano thermal insulation powder, 0.2-0.3% of lignocelluloses, 0.3-0.5% of alum powder, 1-2% of bentonite, 2-4% ofpolyvinyl alcohol 2488, 1-2% of N-methyl trimethylacetamide, 1-2% of 4-methyl catechol, 0.2-0.3% of carboxymethyl cellulose, 3-5% of redispersible latex powder, 0.2-0.3% of pre-gelatinized starch and1-2% of thixotropic agent aluminum-magnesium silicate. By adoption of the raw materials and the adding sequence, the putty gives full play to advantages of the floating beads, and water resistance, alkali resistance, base material bonding strength and thermal insulation performance of the putty are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an inner wall thermal insulation putty and a preparation method. Background technique [0002] Nowadays, with the rapid development of social science and technology and social production, energy and environment have become two major issues that people are increasingly paying attention to, so higher requirements are put forward for energy saving and environmental protection. Based on this, thermal insulation materials came into being. It can effectively reduce the surface temperature and internal temperature of objects without consuming any external energy, so as to save energy, reduce energy consumption and improve safety. my country's existing construction area has reached more than 40 billion square meters 2 , more than 95% of them belong to high-energy buildings, and building energy consumption has reached more than 30% of the total energy consumption o...
