Waterproof coating material

Abstract

The invention discloses a waterproof coating material which is composed of the following raw materials in parts by weight: 30-45 parts of phenolic resin, 26-38 parts of amino resin, 18-30 parts of polycarbonate, 10-18 parts of polypropylene 12-26 parts of aramid fiber, 10-15 parts of nitrile-butadiene rubber, 8-15 parts of alumina ceramic particle, 1-4 parts of graphite, 2-8 parts of titanium ethoxide, 1-5 parts of kaolin, 5-12 parts of antimony trioxide, 6-15 parts of sodium fluosilicate, 2-6 parts of boron nitride and 4-10 parts of stabilizer. The waterproof coating material has the advantages of favorable waterproofness, favorable corrosion resistance, scratch resistance, stable structure, favorable mechanical properties and long service life.

Description

technical field [0001] The invention relates to the field of coating materials, in particular to a waterproof coating material. Background technique [0002] With the development of the economy, solar water heaters have been more and more widely used. The solar battery backplane is an important part of the solar water heater, and its waterproof performance directly determines the safety performance of the solar water heater. Existing battery backplanes generally use waterproof coatings for waterproofing, but there is still room for further improvement in the waterproof performance of existing coating materials. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a waterproof coating material. [0004] In order to achieve the above object, the invention provides a waterproof coating material, which is composed of the following raw materials in parts by weight: 30-45 parts of phenolic resin, 26-38 parts of amin...
