Problems solved by technology

[0002] At present, most of the indoor walls and floors of buildings in my country use JS-Ⅰ / Ⅱ polymer cement waterproof coatings. After the coating is formed into a film, it is a flexible material, and its firmness is low on the base of the wall. Phenomenon of tile hollowing and falling off
In order to improve this phenomenon, usually, a K11 rigid waterproof slurry or JS-Ⅲ polymer cement waterproof coating is used. Although it can improve the hollowing and shedding of ceramic tiles, it greatly reduces the waterproof layer. Waterproof performance, losing the most basic waterproof performance that the waterproof layer must have

Abstract

The invention discloses a bicomponent water-based nano waterproof coating and a preparation method thereof. The bicomponent water-based nano waterproof coating is prepared by mixing a component A and a component B, wherein the component A comprises the following ingredients in parts by weight: 35-37 parts of nano styrene-butadiene rubber, 37-39 parts of nano waterproof emulsion, 22.9-26.7 parts of deionized water, 0.5-0.7 part of a nano silicon auxiliary agent, 0.2-0.4 part of a defoaming agent and 0.2-0.4 part of a preservative; and the component B comprises the following ingredients in parts by weight: 54-56 parts of cement, 26-30 parts of ground calcium carbonate powder, and 16-18 parts of quartz powder. When the bicomponent water-based nano waterproof coating is used, the component A and the component B are mixed and stirred uniformly with each other according to a ratio of the component A to the component B of 1:(1.0-1.2). By using the bicomponent water-based nano waterproof coating, while the waterproof performance is implemented, the contraction stress of a waterproof coating layer during drying can also be reduced, thereby effectively improving or putting an end to the problem that a brick pasted on the waterproof coating layer generates bellowing and falling off. The construction method of the bicomponent water-based nano waterproof coating is consistent with that of a common polymer cement waterproof coating, and the product is environmentally friendly and nontoxic.
