[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.
