Silicon resin environment-friendly waterborne high temperature-resistant coating material as well as preparation and application thereof

Abstract

The invention provides a silicon resin environment-friendly waterborne high temperature-resistant coating material. The silicon resin environment-friendly waterborne high temperature-resistant coatingmaterial is prepared from the following raw materials in parts by weight: 55 to 75 parts of graphene oxide modified methyl silicone resin, 20 to 35 parts of mica powder, 20 to 40 parts of talcum powder, 1 to 10 parts of a dispersant, 1 to 5 parts of a flatting agent, 0.01 to 3 parts of a reinforcing agent, 0.1 to 5 parts of inorganic pigment and 250 to 270 parts of deionized water. The silicon resin environment-friendly waterborne high temperature-resistant coating material prepared by the invention not only has the characteristics of high temperature resistance and good demolding performance, but also is environment-friendly and non-toxic, is good in water solubility and convenient in construction, and has good comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a silicone resin environmental protection water-based high temperature resistant paint. Background technique [0002] Paint, also known as paint, the so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, adding or It is a viscous liquid prepared with organic solvents or water without adding pigments or fillers and adding corresponding additives. [0003] Beginning in the 1950s, a great deal of effort was devoted to research into high-temperature resistant coatings. Traditional high temperature resistant coatings mostly add leaded glass powder or glaze as a high temperature resistant medium to achieve a good temperature resistant effect. In the early 1990s, my country developed a heat-resistant paint with a temperature r...

Problems solved by technology

There are many synthetic methods of silicone resin, among which, the method of synthesizing methylphenyl silicone resin by hydrolysis and condensation method using organochlorosilane as raw material has attracted attention. The raw material of this method is produced by direct method, and the raw material is easy to obtain, with large output and low cost However, a large amount of hydrogen chloride gas is generated in the reaction process of this method. When hydrogen chloride gas is dissolved in water, heat is released, and the hydrochloric acid and heat generated accelerate the spontaneous condensation reaction of the hydrolysis reaction intermediate silanol, making the reaction system easy to gel.
