Abstract

The invention discloses environment-friendly interior wall putty powder and a preparation method thereof. The environment-friendly interior wall putty powder is prepared from the following components as raw materials in parts by weight: 4 to 6 parts of rosin polyether sulfonate, 3 to 5 parts of halloysite nanotubes, 10 to 20 parts of white cement, 20 to 30 parts of inorganic filler, 5 to 8 parts of polyether amide co-modified octatetramethylcyclotetrasilazane, 1 to 2 parts of hydroxypropyl-beta-cyclodextrin, 0.8 to 1.2 parts of a coupling agent and 2 to 4 parts of nano boron fibers. The invention also provides a preparation method of the environment-friendly interior wall putty powder. The environment-friendly interior wall putty powder provided by the invention is good in comprehensive performance and performance stability, extremely strong in water resistance and cohesiveness, and excellent in mechanical property and environmental protection property.

Description

technical field [0001] The invention relates to the technical field of decoration and decoration materials, in particular to an environment-friendly interior wall putty powder and a preparation method thereof. Background technique [0002] Interior wall putty powder is a kind of decorative gel material for leveling the surface of the wall, which is used to fill the gaps in the wall and repair the uneven defects on the painted surface, so that the paint or paint can be applied on the wall to form a smooth surface. and uniform paint film. Interior wall putty powder is an indispensable supporting material in the process of architectural coatings. With the improvement of people's awareness of living environment and the diversification of places of use, the requirements for interior wall putty powder are getting higher and higher, not only requiring it to have excellent cohesiveness, water resistance, crack resistance, and It does not fall off, and it is also safe, green and en...
