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
[0008] Most of the known interior wall putties in our country are prepared from materials such as talc powder, double fly powder, carboxymethyl cellulose and polyvinyl formal adhesive (107 glue). Although the cost of raw materials is low, the process is complicated and the overall cost is high. , especially containing harmful substances such as formaldehyde, which have a great impact on the human nervous system, especially infants and the elderly and infirm, are more harmful, and even cause serious diseases

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. It is used to fill the gaps in the wall and repair the uneven defects on the painted surface, so that the paint or lacquer can be applied on the wall to form a smooth and smooth surface. Uniform paint film. Since interior wall putty is widely used and can be used in many different places, the required functional requirements vary according to the place of use. Thereby, existing invention patent about interior wall putty.
