Anti-cracking waterproof coating and preparation method thereof

Abstract

The invention provides anti-cracking waterproof coating and a preparation method thereof; the anti-cracking waterproof coating comprises silicone-acrylic emulsion, acrylic resin, ethylene-vinyl acetate copolymer, epoxy resin, graphene, glass fiber, methyl cellulose, glass beads, high-viscosity attapulgite clay, glyceryl stearate, a filling agent, and a defoaming agent. The preparation method comprises: subjecting acrylic resin and ethylene-vinyl acetate copolymer to modifying reaction with graphene, adding the remaining components batch by batch, and mixing well to obtain the anti-cracking waterproof coating. The anti-cracking waterproof coating is applicable to the building field, has good waterproof effect and good anti-cracking and anti-peeling effects, provides greatly improved application safety for a building and extended life for the building, and has good applicable value.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a crack-resistant waterproof coating and a preparation method thereof. Background technique [0002] The waterproof problem of buildings is not only related to people's work and living environment, but also affects the service life of buildings. With the rapid development of the national economy, my country's engineering construction is also booming, especially the construction of various projects such as housing, sports facilities, and road traffic, which provide material conditions for improving people's living standards. How to do a good job in various engineering constructions Waterproof and corrosion resistance issues are the most concerned issues of the project construction party. To overcome technical difficulties, we must rely on scientific and technological progress and adopt advanced technologies, including the application of new materials. In the early days,...

AI Technical Summary

Problems solved by technology

In the early days, people used asphalt and asphalt as waterproof materials. The use of this material not only consumes a lot of energy during construction, causes serious environmental pollution, poor adhesion, but also has poor weather resistance. It is easy to become hard and brittle in winter, and easy to stick and melt in summer; This waterproof material has the problems of difficult construction, short service life and poor waterproof performance.

[0003] Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature.

Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breakage, delamination, etc. When used for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It takes a lot of money and labor to repair every few years, which not only disrupts people's normal life, work and production order, but also affects the service life of the entire building.
