Abstract

The invention discloses an environment-friendly waterproof coating and a preparation method thereof and relates to the technical field of waterproof coatings. The environment-friendly waterproof coating is prepared from a liquid and powder, wherein the liquid comprises components in parts by weight as follows: 100-150 parts of an ammonia-free styrene-acrylic emulsion, 0.5-1 part of a defoaming agent, 0.5-1 part of a dispersant, 0.1-0.5 parts of a bactericide and 0-20 parts of deionized water; the powder components in parts by weight as follows: 400-600 parts of 42.5-grade ordinary Portland cement, 150-300 parts of river sand, 150-300 parts of quartz sand, 5-10 parts of nano negative ion powder, 5-10 parts of superfine tourmaline powder, 0.1-1 part of cellulose ether and 1-5 parts of a naphthalene water reducer. The waterproof coating has no pungent smells during construction stirring, releases negative ions which are beneficial to human health during usage and has excellent tensile property.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to an environmentally friendly waterproof coating and a preparation method thereof. Background technique [0002] The waterproof coating is a two-component water-based waterproof coating prepared in a certain proportion from an organic liquid material composed of acrylate emulsion and various additives, and an inorganic powder composed of special cement and various fillers. Brush on the surface of the substrate and form a waterproof coating after curing. It is suitable for waterproofing and moisture-proofing of toilets, kitchens, balconies, floors, pools, and basements. [0003] At present, waterproof materials include waterproof coatings and waterproof coiled materials. The construction process of waterproof coiled materials is complicated and the cost is high; the process of waterproof coatings is simple and the cost is low, but the waterproof coatings are mainly rigid and wat...
