Waterproof antibacterial coating for exterior walls of buildings applied in mycotic environment and manufacturing method thereof

Abstract

The invention discloses a waterproof antibacterial coating for exterior walls of buildings applied in a mycotic environment and a manufacturing method thereof. The waterproof antibacterial coating comprises three parts of a component A, a component B and a component C, wherein the component A is a viscous solution involving the steps that under the combined action of ligninase and diluted hydrochloric acid, an aqueous solution composed of acid-modified polysaccharides and trace useless water-soluble organic matters and water is acquired from schizonepeta stem and houttuynia cordata root, and after heating concentration is carried out, the viscous solution is obtained; the component B is a mixed liquid involving the steps that activated carbon micro powder, chitosan antibacterial gel and Bossini nano-latex paint are mixed in absolute ethyl alcohol and then react with sodium hydroxide, after heating steaming from ethyl alcohol is carried out at 60-70 DEG C, the mixed liquid of a hydroxylated organic matter and activated carbon powder is obtained; the component C is a mixed dry fiber involving the steps that the schizonepeta stem and the houttuynia cordata root are subjected to complete dehydration and then physical mixing, and the mixed dry fiber is obtained. The waterproof antibacterial coating for the exterior walls of the buildings applied in the mycotic environment and the manufacturing method thereof have the advantages that the manufacturing process is detailed and easy to implement, the antibacterial effect is good, the effect is lasting, and the waterproof antibacterial coating is green, environmentally friendly and pollution-free, has no pungent smell, is resistant to water, and has a self-cleaning function.

Description

technical field [0001] The invention relates to the field of environmental protection coatings, in particular to a waterproof and antibacterial coating for building exterior walls and a manufacturing method thereof, which are applied in a mold environment. Background technique [0002] Anti-mildew coating has dual effects of architectural decoration and anti-mildew effect. It has a wide range of high-efficiency and long-term bactericidal and inhibitory capabilities against mold and yeast. The fundamental difference from ordinary decorative coatings is that a certain amount of mold inhibitors or inorganic nano-powders that inhibit mold are added to the manufacturing process of anti-mold coatings. Conventional organic anti-mold coatings contain biotoxic drugs, while inorganic anti-mold coatings are a protective coating that can inhibit the growth and development of mold without containing bio-toxic drugs. However, organic anti-mildew coatings are biologically toxic and genera...

AI Technical Summary

Problems solved by technology

However, organic anti-mildew coatings are biologically toxic and generally cannot be used in residential environments, while non-anti-mildew coatings are easier to powder and fall off in actual use due to powder compatibility problems, and generally contain precious metals (such as nano-silver, etc.) , poor practicality and economy

[0003] Waterproof and antibacterial coatings in the prior art are limited by the lack of technical field and practical experience, and waterproof and antibacterial coatings in a complete sense have not really appeared. Therefore, there is still no detailed and easy-to-implement manufacturing process, good antibacterial effect, and effective Durable, environmentally friendly, pollution-free, non-irritating odor, water-resistant, waterproof and antibacterial coating with self-cleaning function
