Problems solved by technology

[0007] Among the above-mentioned interior wall putty powders, some are for improving water resistance, and some are for the functions of adsorption and health care. The former is easy to hollow, peel and crack, while the latter has low bonding strength, poor adhesion and poor water resistance.
In terms of the preparation of environmentally friendly putty, the formula and process procedures are complicated, and it contains raw materials that are chemically unstable, prone to yellowing and black spots

Abstract

The invention discloses an environmentally-friendly interior wall putty powder, a putty paste, and preparation methods of the putty powder and the putty paste. The putty powder comprises, by weight, 45-72 parts of talcum powder, 18-30 parts of heavy calcium carbonate, 5-10 parts of calcium bentonite, 0.6-1.5 parts of carboxymethylcellulose sodium, 1-5 parts of polyacrylamide, 0.3-1.7 parts of hydroxyethyl cellulose, 0-20 parts of building gypsum powder, 0-0.8 parts of carboxymethyl cellulose, 0-8 parts of alpha-pregelatinized starch, 0-3 parts of hydroxypropyl methyl cellulose and 0-0.5 parts of sodium dodecyl benzene sulfonate. The preparation method of the putty powder comprises the following steps: uniformly mixing the above components, stirring for 10-15min, and discharging the above obtained mixture. The putty paste is obtained by adding water having a weight 0.3-0.5 times the weight of the putty powder and uniformly stirring. The putty powder/putty paste contains no or a tiny amount of formaldehyde and an extremely low content of heavy metal elements, is an environmentally-friendly product, and has the advantages of excellent impact resistance, excellent hydrophobicity and waterproofness, high elasticity, good crack resistance, stable storage and easy construction.

Description

technical field [0001] The invention belongs to the technical field of wall surface decoration materials, and is a decorative gel material for construction, in particular to an environment-friendly putty powder and putty paste, and a preparation method thereof. Background technique [0002] Interior wall putty is a kind of decorative gel material for leveling the surface of the wall.
