Problems solved by technology

[0002] At present, there are many kinds of waterproof emulsions used on building surfaces in the market, and the quality is uneven. Some contain toxic and harmful substances such as benzene and formaldehyde. Using this waterproof emulsion is harmful to the human body and the home environment. Although some waterproof emulsions are not toxic material, but there are disadvantages such as poor water resistance, weak adhesion, easy foaming and falling off, causing water leakage on the waterproof surface, etc.

Abstract

The invention discloses a water-based environment-friendly non-toxic and harmless elastic waterproof emulsion and a preparation method thereof. The emulsion is characterized by comprising the following components in parts by weight: 1.5-2.5 parts of dispersant, 0.8-1.2 parts of defoamer, 8-13 parts of plasticizer, 190-220 parts of coarse whiting, 0-10 parts of rutile titanium dioxide, 80-120 parts of wollastonite powder, 450-550 parts of elastic emulsion, 3-5 parts of bactericide, 1-2 parts of edible high-gluten flour, 1.8-2.2 parts of thickener and 170-190 parts of water in manners of mixing and fully agitating. The ductility of the obtained product after film formation is 370-450%, and the tensile strength is 1.8-2.4Mpa by test detection. The product is innocuous and unpoisonous, strong in water tolerance, not easy to blister and fall off, and applicable to interior and exterior wall spaces, and the wall space of a toilet, can completely prevent the waterproof surface from leaking, and accords with the JC / T864-2008 executive standards (I type).

Description

technical field [0001] The invention relates to a waterproof emulsion, in particular to a water-based, environmentally friendly, non-toxic and harmless elastic waterproof emulsion and a preparation method thereof. Background technique [0002] At present, there are many kinds of waterproof emulsions used on building surfaces in the market, and the quality is uneven. Some contain toxic and harmful substances such as benzene and formaldehyde. Using this waterproof emulsion is harmful to the human body and the home environment. Although some waterproof emulsions are not toxic Substance, but there are disadvantages such as poor water resistance, weak adhesion, easy foaming and falling off, resulting in water leakage on the waterproof surface. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide an elastic waterproof emulsion that is non-toxic, harmless, strong in water resistance, not prone to foamin...
