Abstract

The invention discloses environment-friendly putty powder which is characterized in comprising the following components in parts by weight: 20-30 parts of palygorskite, 10-20 parts of montmorillonite,15-20 parts of white cement, 1-3 parts of lambda-carrageenan modified polyquaternium-10, 2-4 parts of rosin modified cationic guar gum, 1-3 parts of konjac gum, 0.5-1.5 parts of epoxy-terminated hyperbranched polyphosphate and 0.5-1.5 parts of amino-terminated hyperbranched polybenzimidazole. The invention further provides a preparation method of the environment-friendly putty powder. The environment-friendly putty powder disclosed by the invention is good in comprehensive performance, sufficient in strength and adhesive force, high in hardness, good in water resistance, free of phenomena ofhollowing, peeling, cracking and falling off after being wetted by water, and safe and environment-friendly to use.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to an environmentally friendly putty powder and a preparation method thereof. Background technique [0002] With the development of society and the improvement of living standards, people's awareness of environmental protection and health is constantly increasing, and their requirements for the comfort and safety of the living environment are getting higher and higher. Putty powder, as a common decorative material on the surface of a flat wall, plays a vital role in the comfort and safety of the living environment. The ideal putty powder requires not only excellent adhesion and water resistance, but also It is safe, green and environmentally friendly, and has a long service life. [0003] Putty powder is based on inorganic gel material, finely processed with bonding materials and other additives, and is an indispensable product before painting. Putty powder i...
