Problems solved by technology

[0003] The large white putty admixture used in traditional building decoration is mainly produced from polymer glue such as polyvinyl alcohol, carboxymethyl cellulose, carboxymethyl starch, and pregelatinized starch; but polyvinyl alcohol glue contains formaldehyde, which is harmful to the human body. , does not meet the requirements of environmental protection, and carboxymethyl starch and pregelatinized starch do not contain harmful substances, but their cohesive force and mildew resistance are poor. If they are added in a large amount in the putty powder, it will easily cause the putty powder to become mildewed and cause the putty powder to fall off. Unsightly, causing huge waste
At the same time, the traditional putty powder has poor scrub resistance, which leads to pulverization in subsequent construction. Therefore, it is urgent to find a more environmentally friendly and anti-mildew putty powder with good scrub resistance to solve the above problems

Abstract

The invention discloses a mildew-proof putty powder.The mildew-proof putty powder is prepared from, by weight, 800-1200 parts of 200-mesh talcum powder, 8-12 parts of bentonite, 20-30 parts of cellulose, 8-15 parts of starch glue, 3-6 parts of nano-silica, 2-5 parts of sesbania gum and 0.2-1 part of mildew preventive.The mildew preventive is prepared from, by weight, 5-10 parts of chitosan, 3-6 parts of polyquaternium, 2-5 parts of chloroacetamide, 5-10 parts of acetic acid, 1-2 parts of allicin and 1-2 parts of citric acid.The mildew-proof putty powder is not likely to mildew, not likely to shed due to the strong adhesive power, high in compressive strength and flexural strength, resistant to water and scouring, good in dispersity and good in painting effect.

Description

technical field [0001] The present invention relates to building materials. More specifically, the present invention relates to a mildew-resistant putty powder and a preparation method thereof. Background technique [0002] Putty powder is a kind of decorative material for leveling the surface of the wall. It is made of inorganic gelling material as the base material and finely processed with bonding materials and other additives. It is an indispensable product before painting. Apply on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. [0003] The large white putty admixture used in traditional building decoration is mainly produced from polymer glue such as polyvinyl alcohol, carboxymethyl cellulose, carboxymethyl starch, and pregelatinized starch; but polyvinyl alcohol glue contains formaldehyde, which is harmful to the human body. , does not meet the requirements of environmental protection, and carboxymethyl starc...
