Abstract

The invention provides a mould-proof putty powder, and belongs to the technical field of building chemical paint. The mould-proof putty powder is mainly prepared from, by weight, 1000 parts of talcumpowder, 10 to 15 parts of fiber, 5 to 8 parts of starch glue, 5 to 10 parts of pregelatinized starch, 2 to 4 parts of a delayed coagulant, 1 to 2 parts of a lubricant, 0.3 to 0.7 part of a composite mildew-resistant bactericide, and 10 to 15 parts of bentonite. The formula of the mould-proof putty powder is simple; manufacturing cost is low; and technical problems of conventional mould-proof puttypowder that service life is short, the durability is poor, and mould-proof effect sustainability is poor are solved.

Description

technical field [0001] The invention relates to the technical field of construction chemical coatings, in particular to an anti-mold 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. Most of the putty currently on the market is affected by seasonal changes, rainfall and air conditions, especially in humid and rainy areas such as the south, or on wet surfaces such as bathrooms and basements, the wall putty layer is prone to breed bacteria, mold and other microorganisms. It will affect the beauty of the wall and will seriously damage human health. [0003] Therefore, people's demand for high-performance anti-mold putty powder is also increasing. But although the existing anti-mold type putty powder has better anti-mol...
