Anti-crack and anti-falling coating and preparation method

Abstract

The invention discloses an anti-crack and anti-falling coating and a preparation method, which belong to the technical field of coatings. The coating is prepared from the following components: modified polyurethane, modified epoxide resin, glass fiber, aluminum oxide, sodium stearate, paste attapulgite clay, putty cream, kieselguhr, a defoaming agent, a filling agent, pigment, and appropriate amount of water. The preparation method comprises the steps of weighing the modified polyurethane and the modified epoxide resin, adding into a reaction kettle, adding appropriate amount of water, and carrying out mixed reaction to obtain a mixture a1; adding the paste attapulgite clay, uniformly stirring, putting in an ultraphonic condition, and obtaining a mixture a2; adding the putty cream, the kieselguhr, the defoaming agent and the filling agent, stirring, shearing, adding a pigment, and uniformly mixing to obtain the coating. The coating provided by the invention not only has a better waterproof and anticorrosion effect, but also has a better anti-crack and anti-falling performance. In addition, the preparation method is simple and practicable, and has a better application value.

Problems solved by technology

[0003] With the improvement of people's living standards and the rapid development of the real estate industry, people's requirements for the decoration industry are getting higher and higher, and the performance requirements for building materials are getting higher and higher, which not only improves the quality, but also prolongs the durability of use. Necessary measures for energy saving and consumption reduction of buildings. Other performances of existing environmental protection materials for walls are not ideal. Shedding, anti-bubble coating material to meet the requirements of modern decoration

In recent years, a variety of inferior decoration materials have appeared on the market, and improper selection also poses hidden dangers to people's life safety

At present, most of the interior decoration coatings on the market are easy to fall off when they are used in a low-temperature and humid environment or for a long time.
