Waterborne waterproof paint and preparing method thereof

Abstract

The invention discloses waterborne waterproof paint comprising a component A and a component B. The component A is a liquid material, the component B is a powdery material, and the weight ratio of thecomponent A to the component B is 1:(1.2-1.5). The component A comprises, by weight, 90-95% of a styrene-acrylic emulsion, 0.10-0.20% of a preservative, 0.10-0.20% of a dispersing agent, 0.20-0.30% of a defoaming agent, 0.5-1% of an anti-skinning agent and 4-6% of water. The component B comprises, by weight, 25-35% of cement, 25-35% of wollastonite, 35-45% of quartz powder and 0.4-0.7% of a waterreducing agent. An oxime compound is adopted as the anti-skinning agent, free radicals can be generated in the paint film forming process, the anti-skinning agent can catch the free radicals and interrupt the paint film oxidative polymerization effect; the anti-skinning agent quite easily volatiles, cannot stop the polymerization film formation of the free radicals, and extremely easily volatilesunder the high vapor pressure, the space in a tank is filled with generated vapor, an oxygen isolation effect is realized, and the skinning phenomenon of the waterproof paint in the use process is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a water-based waterproof paint and a preparation method thereof. Background technique [0002] In recent years, with the development of the construction industry, the use of coatings has become more and more advanced and novel. Buildings are vulnerable to the erosion and penetration of rainwater, groundwater and other moisture. In response to this phenomenon, more and more types of waterproof materials have been introduced in the prior art, and waterproof materials have also become an indispensable part of construction engineering structures. Waterproof coatings, as one of them, have also been developed rapidly. [0003] However, with the development of waterproof coatings, due to technical reasons, the waterproof coating products on the market are mixed. Neither long-term waterproof coatings nor short-term waterproof coatings can effectively achieve their promotional ...

Problems solved by technology

[0003] However, with the development of waterproof coatings, due to technical reasons, the waterproof coating products on the market are mixed. Neither long-term waterproof coatings nor short-term waterproof coatings can effectively achieve their promotional functions, especially after being soaked in water for a long time. The phenomenon of skinning occurs in a large area, and the conventional waterproof coatings in the prior art are slightly improperly stored and used at improper timing, and skinning phenomenon will also occur
