Abstract

The invention relates to the technical field of building materials, particularly to mildew-proof and antibacterial putty powder, a preparation method and a use method thereof, wherein the mildew-proofand antibacterial putty powder is prepared by mixing the following materials: Portland cement, ash calcium, talcum powder, hydroethyl methyl cellulose, a mildew preventive, polyvinyl alcohol and amylase. The use method of the putty powder comprises the step of uniformly mixing the raw materials with water according to a mass ratio of (10-5):3. Compared with the prior art, the mildew-proof additive selected for specifically inhibiting mildew on the wall surface is compounded with putty to achieve the mildew-proof and antibacterial functional putty, so that water resistance, moisture resistanceand aging resistance of a wall decorative surface layer are achieved, and the defects that mildew and black spots grow on a wall due to indoor air moisture or wall surface permeation are overcome. According to the putty prepared by the method disclosed by the invention, all harmful substances, mould resistance and all physical properties meet the standards of GB18582-2008 (water-based wall putty), HG / T 3950-2007 (table 2) and JG / T 298-2020 (water-resistant N).

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an anti-mildew and anti-bacterial putty powder and a preparation method and application method thereof. Background technique [0002] The ubiquitous shortcoming of existing putty powder concentrates on three aspects: [0003] 1. Water-resistant but not moisture-proof, the surface film-forming layer is water-resistant, but the inner layer is loose and hollow due to moisture; [0004] 2. Moisture-proof and not aging-resistant, although the inner layer of the surface is water-resistant and moisture-proof, but the bond strength is low in a short period of time or within two or three years, there will be chalking, peeling, peeling, etc.; [0005] 3. Waterproof and moisture-proof but not mildew-proof, because the room is humid for a long time or the rainy season in the south will cause mold and mildew spots. [0006] In view of this, apply for this patent. Co...
