Problems solved by technology

Due to the lack of building gypsum air-hardening materials, the wall-scraping putty is almost not water-resistant, and its adhesion is poor. After painting, there are often engineering quality problems such as shedding, wrinkling, and peeling.
[0003] Although some existing putty powders pay attention to their cohesiveness and strength, high viscosity and good adhesion, the environmental index of this kind of putty powder is slightly lower.

Abstract

The invention provides environmental-friendly high-adhesion putty powder and relates to the technical field of architectural chemical coatings. The environmental-friendly high-adhesion putty powder disclosed by the invention mainly comprises the following raw material components in parts by weight: 200-350 parts of gypsum, 20-30 parts of pregelatinized starch, 10-15 parts of starch mud, 3-10 partsof carboxymethyl cellulose, 8-15 parts of hydroxypropyl methyl cellulose, 5-10 parts of lauryl sodium sulfate, 3-4 parts of hydroxyethyl cellulose, 5-8 parts of organic polymers, 10-20 parts of bentonite and 10-20 parts of ground limestone superfine powder. According to the putty powder formula disclosed by the invention, the wall adhesion of putty is improved, a high environmental protection index is ensured, and the putty powder can be completely adhered to the wall and is very firm.

Description

technical field [0001] The invention relates to the technical field of construction chemical coatings, in particular to an environment-friendly high-adhesion putty powder. Background technique [0002] In the architectural decoration industry, the purpose of putting putty on the wall is to fill the pores of the construction surface and correct the curve deviation of the construction surface, laying a good foundation for obtaining a smooth and uniform paint surface. Batch wall putty is composed of building gypsum as the main raw material. Building gypsum has certain water resistance, but many manufacturers reduce the amount of building gypsum. In order to reduce costs, the more important thing is to increase the whiteness of the product and smoother construction. Raw materials are more sandable. Due to the lack of air-hardening materials for building gypsum, the wall-scraping putty is almost not water-resistant, and its adhesion is poor. After painting, there are often engin...
