Bicomponent water-based nano waterproof coating and preparation method thereof
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.
