Ash-calcium-based water-resistant putty

Abstract

The invention discloses ash-calcium-based water-resistant putty. The ash-calcium-based water-resistant putty is characterized in that the putty is prepared from the following components in parts by weight: 15-20 parts of gel, 80-85 parts of a filling material, 0.4-0.5 part of water-retaining agent cellulose, 0.03-0.05 part of a thickener, 1-3 parts of 84 disinfectant powder, 10-20 parts of glass powder, 0.3-0.5 part of a mold inhibitor, 1-2 parts of a quantum catalyst and 3-5 parts of mica powder. The ash-calcium-based water-resistant putty has the beneficial effects that the putty is less liable to mould; the putty is strong in adhesive force, and is less liable to fall off; the putty is hard after drying, is good in water resistance, and is washing resistant; the dispersibility is good;the brushing effect is good.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a gray calcium-based water-resistant putty. 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 starch and pregelatinized starch do not contain ...

AI Technical Summary

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 chalking in subsequent construction, is not resistant to water, and shows low hardness. Therefore, it is urgent to find a more environmentally friendly, good scrub resistance, high hardness after drying and water-resistant powder to solve the above problems.
