Abstract

The invention provides waterproofing slurry for building roofs and a preparation method thereof. The slurry comprises the following components: styrene-acrylic emulsion, modified organic silicon resin, epoxy resin, pentaerythritol triacrylate, chlorinated paraffin, kaolin, ground calcium carbonate, vermiculite power, graphene, attapulgite, barium sulfate, mica powder, a defoaming agent and a filler. The preparation method comprises: performing a modification reaction on the styrene-acrylic emulsion, the epoxy resin and the graphene first, and then mixing a product obtained after the reaction with the remaining components uniformly to obtain the slurry. The slurry provided by the invention is applied to roof construction, not only can improve waterproof and anti-crack properties of roofs but also has certain characteristics of corrosion resistance and aging resistance, and has a good application value.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof slurry for building roofs and a preparation method thereof. Background technique [0002] The cracking and leakage of buildings and various structures is almost a common quality problem in today's concrete structures, and it is also a difficult problem that people continue to explore and study. At present, traditional paints are widely used in the decoration of building walls. Most of the paints are limited to high elasticity, poor water resistance and water resistance, low tensile strength, and general adhesion. Therefore, it is generally only used for interior decoration. Nowadays, people pay more and more attention to the living environment, so the outdoor decoration is getting more and more attention. But outdoors are different from indoors. Environmental pollution is getting more and more serious. The rainwater outside is acid rain, so waterproofing...
