Abstract

The invention discloses a mold-proof, antibacterial and waterproof coating and a preparation method thereof. The coating is prepared from a liquid component and a powder component in the mass ratio ofaddition amount being 1:(3.0-4.0), wherein the liquid component comprises raw materials in percentage by mass of the liquid component as follows: 20wt%-30wt% of a No.1 styrene-acrylic emulsion, 20wt%-30wt% of a No.2 styrene-acrylic emulsion, 0.20wt%-0.30wt% of a wetting dispersant, 0.10wt%-0.20wt% of a defoaming agent, 40wt%-50wt% of water and 5wt%-10wt% of copper sulfate pentahydrate; the powdercomponent comprises raw materials in percentage by mass of the powder component as follows: 45wt%-55wt% of cement, 40wt%-50wt% of quartz sand, 3wt%-5wt% of quartz powder, 0.02wt%-0.05wt% of celluloseether, 0.4wt%-0.5wt% of a water reducer, 1wt%-2wt% of silica fume and 1wt%-2wt% of an inorganic silver ion antibacterial agent. The coating has excellent mold-proof and antibacterial effects and caneffectively inhibit peculiar smells emitted by kitchens and toilets due to mildewing of waterproof layers, prevent corrosion of microorganisms to the waterproof layers and prolong the service life ofthe waterproof layers.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a mildew-proof, antibacterial and waterproof coating and a preparation method thereof. Background technique [0002] In recent years, urban and rural construction has shown a trend of rapid growth, and various high-rise buildings and underground projects are inseparable from waterproofing. With the development of the construction industry and the increasing number of underground dam projects, people have put forward higher requirements for the waterproofing of buildings and the moisture-proof and anti-corrosion materials of underground projects. Since the construction environment of waterproof coatings is mostly humid and warm, microorganisms are easy to breed and multiply in this environment. If things go on like this, the waterproof coating layer will breed a large number of fungi, mold and other microorganisms, which will seriously affect the living experience and human he...
