Abstract

The invention belongs to the technical field of building materials, and particularly relates to an internal wall putty which comprises the following components in parts by weight: 150-300 parts of white cement, 500-900 parts of calcium carbonate powder, 10-50 parts of grey desert soil, 1-8 parts of cellulose ether, 7-30 parts of polymer latex powder, 1-10 parts of water repellent, 0.05-3 parts of starch ether and 0.5-7 parts of wood fiber. Compared with the prior art, the internal wall putty has the advantages that 107 glue water or 801 glue water is not used, thus formaldehyde is not contained, the environment is protected; and pregelatinized starch is not used, and the water repellent is added, thus the internal wall putty has the function of preventing water and moisture. In addition, with the white cement and the calcium carbonate powder as the strength basis and the grey desert soil as an auxiliary strength material, the strength of the internal wall putty is ensured; due to the synergistic effect of the cellulose ether and the starch ether, the water-retaining property and the application property of the internal wall putty are ensured; and because the polymer latex powder is added, the flexibility of the internal wall putty and the adhesion of the polymer latex powder and the wall are improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly, water-resistant and moisture-proof interior wall putty and a production process thereof. Background technique [0002] In the current decoration market, interior wall putty is widely used as a leveling material for wall protection. Because it is used on the interior wall, the environment of the interior wall is not as harsh as the outdoor environment, so people generally do not have high requirements for the putty on the interior wall, which leads to the generally poor quality of the putty on the interior wall. [0003] The main component of the current popular interior wall putty is Shuangfei powder (mainly composed of calcium and magnesium). By adding 107 glue (scientific name is polyvinyl formal adhesive, it is an adhesive formed by a solution or emulsion with water as the medium). agent), 801 glue (made by polyvinyl alcohol and...
