Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with specific embodiments.

[0029] The invention relates to a formula of anti-mildew paint, which is prepared by cement, quartz sand, heavy calcium powder, light calcium carbonate, ash calcium powder, talcum powder, anti-cracking fiber and additives in a certain proportion. The weight ratio of each component is 19% of cement, 28% of quartz sand, 29% of heavy calcium powder, 6% of light calcium carbonate, 12% of lime calcium powder, 4% of talcum powder, 1.5% of anti-cracking fiber and 0.5% of additive. The particle size of quartz sand is 80-120 mesh; the additives are hydroxypropyl methylcellulose, preservative (cetyl ammonium bromide), antifungal agent (titanium-loaded zinc composite hydroxyapatite powder) and light-stabilized agent (hindered amine light stabilizer 662), the weight ratio of the four is 8.0:1.0:0.5:0.5.

Abstract

The invention discloses a formula of anti-mildew paint, which is composed of cement, quartz sand, heavy calcium powder, light calcium carbonate, lime calcium powder, talcum powder, anti-cracking fiber and additives, and the weight ratio of each component is cement 19 %, quartz sand 28%, heavy calcium powder 29%, light calcium carbonate 6%, ash calcium powder 12%, talcum powder 4%, anti-crack fiber 1.5%, additive 0.5%; the additive is hydroxypropyl methylcellulose , preservatives, fungicides and light stabilizers. The anti-mildew paint of the present invention is stirred with a mixer to form a dry mixture, which can be used after adding a certain proportion of water and stirred at the construction site, and can be constructed by spraying or scraping. The coating of the present invention has strong adaptability to mildew-prone environments, has the advantages of antibacterial and anti-mildew effects, moisture resistance, water resistance, strong adhesion, etc., and generally can reach a service life of more than 10 years. The invention also provides a preparation method of the paint.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a formula and a preparation method of an anti-mildew paint. Background technique [0002] Architectural coatings are materials that use different construction techniques to paint various base materials of buildings, such as walls, columns, structural ceilings, etc., to form a complete and tough protective film. Architectural coatings have bright colors, rich shapes, and good decorative effects; excellent performance, diverse functions, and good protection effects; convenient construction, easy maintenance, and low unilateral cost; light weight, energy saving, and high work efficiency. Its development prospects will be very impressive. . However, the organic components in traditional coatings provide a rich material basis for the growth and reproduction of microorganisms. Microbes use these nutrients to undergo biodegradation, biochemical synthesis, met...
