[0040] A method for preparing an interior wall thermal insulation plaster, comprising the following steps:
[0041] S1. Weigh gypsum, lightweight aggregate, filler, air-entraining agent, cellulose, rubber powder, starch ether, and retarder respectively, and add them to the powder mixer in sequence according to the formula and stir evenly.
[0042] S2. Weighing water is 50% of powder total amount, the mixed powder that step S1 is made is added to the water of formula quantity;
[0043] S3. After stirring evenly according to the obtained step S2, stir evenly to get the inner wall thermal insulation plastering.
Embodiment 1
[0045] In the step S1, the lightweight aggregate is vitrified microbeads and airgel, the filler is heavy calcium powder and wollastonite powder, the air-entraining agent is saponin powder, and the cellulose is hypromellose base cellulose, the rubber powder is VAE rubber powder, and the retarder is a protein retarder, and each component is added in sequence according to the following mass ratios:
[0046]
Embodiment 2
[0048] In step S1, the lightweight aggregate is vitrified microbeads and expanded perlite, the filler is heavy calcium powder and talcum powder, the air-entraining agent is sodium dodecylbenzenesulfonate, the cellulose is ethyl cellulose, and the rubber powder is Resin rubber powder, retarder is sodium citrate, and each component is added in order according to the following mass ratio:

Abstract
The invention discloses an interior wall thermal insulation plaster, which comprises the following components by mass: 55 to 75 parts of gypsum; 8 to 25 parts of lightweight aggregate; 10 to 30 parts of filler; 0.1 to 0.3 part of an air entraining agent; 0.1 to 0.3 part of cellulose; 0.5 to 1.5 parts of rubber powder; 0.05 to 0.1 part of starch ether; and 0.05 to 0.15 part of a retarder. The internal wall heat insulation plastering method is convenient and simple in manufacturing, the material has the advantages of being high in strength, low in heat conductivity coefficient, good in heat insulation effect and the like, construction operation is easy and convenient, and good market prospects are achieved.
Description
technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to an interior wall thermal insulation plaster. Background technique [0002] For interior wall insulation, people generally care about three concerns: one is the indoor area; the other is the indoor environmental protection; the third is the fire performance. Gypsum thermal insulation plastering materials have been widely recognized by the market. They can replace the plastering layer, not only do not occupy the indoor area, but also save a lot of money. They can also pass the standard test in terms of environmental protection. Due to different materials and processing methods, existing interior wall insulation materials have the problems of poor strength, easy powder drop, relatively high thermal conductivity, and poor thermal insulation effect. Contents of the invention [0003] The purpose of the invention is to solve the problems existing in the prior ar...
