Problems solved by technology

[0002] Buildings are prone to mold in humid climates or environments, especially during the rainy season in the south. Houses with low floors or basements are prone to mold. Mold spores are easy to scatter and be inhaled by the human body, affecting human health. Mold also affects the appearance of the wall. The treatment after mold generation often requires repainting, which brings a lot of inconvenience
Even the walls painted with high polymer topcoats still have mildew growth, but there are no products on the market that treat the surface of such walls with mildew and mildew prevention

Abstract

Belonging to the technical field of preparation of mould inhibitors for building walls, the invention discloses a preparation method of a mould removal and mould-proof spray for high polymer topcoat walls. The method includes raw material preparation, pre-mixing, blending and other steps. Specifically, calcined shell powder is adopted as the mould removal component, a modified montmorillonite mould-proof agent is used as the long-acting mould-proof agent, and specific formula design is carried out for high polymer topcoat walls to adapt high polymer paint treated wall surfaces. The preparationprocess adopts components harmless to the human body, the prepared product has sterilizing and antibacterial efficacy, and also can reach a long-acting bacteriostatic effect after rapid sterilization. The mould removal and mould-proof spray obtained by the method provided by the invention has good compatibility with high polymer topcoat walls, also can restore the brightness of walls after beingadded with corresponding pigments, and can be attached to the surfaces of wall firmly after use without stripping and shedding.

Description

technical field [0001] The invention belongs to the technical field of preparation of antifungal agents for building walls, in particular to a method for preparing a mildew and antimold spray for polymer topcoat walls. Background technique [0002] Buildings are prone to mold in humid climates or environments, especially during the rainy season in the south. Houses with low floors or basements are prone to mold. Mold spores are easy to float and be inhaled by the human body, affecting human health. Mold also affects the appearance of the wall. The treatment after mold generation often requires repainting, which brings a lot of inconvenience. Even on walls painted with polymer topcoats, there are cases of mold growth, but there is no product on the market that is designed to remove and prevent mildew on the surface of this type of wall. Contents of the invention [0003] In order to solve the above problems, the present invention provides a kind of high polymer surface pai...
