Organic-inorganic colorful composite coating

Abstract

The invention discloses an organic-inorganic colorful composite coating which is prepared from the following raw materials in parts by weight: 80-100 parts of water-borne epoxy resin, 30-40 parts of kaolin, 10-15 parts of infrared reflecting pigment, 15-20 parts of feldspar powder, 5-10 parts of mica powder, 5-10 parts of vermiculite powder, 2-5 parts of cationic crosslinker, 2-5 parts of coalescing agent, 3-7 parts of cellulose ether, 5-10 parts of inorganic protecting adhesive, 2-5 parts of wetting agent, 2-5 parts of curing accelerator, 2-3 parts of dispersant, 1-3 parts of defoamer, 1-3 parts of reactive diluent, 1-3 parts of PH regulator, 15-25 parts of titanium dioxide, 10-20 parts of silicon dioxide, 15-20 parts of ethylene glycol, 2-6 parts of surfactant, 3-6 parts of mica iron oxide, and 300-500 parts of deionized water. The organic-inorganic colorful composite coating is rich in ingredients, very high in physical property and chemical property, and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of multicolor coatings, in particular to organic-inorganic composite multicolor coatings. Background technique [0002] In recent years, multi-color paint has attracted more and more attention from people and the market. This kind of environmentally friendly paint can be sprayed on the wall with a special spray gun to get the same pattern and color as natural granite materials. The coating finish Bright and colorful, convenient construction, no pollution to the environment. At present, colorful preparation methods are mainly divided into two categories: inorganic gel method and organogel method. In the inorganic gel method, the synthetic nano-layered silicate is used as the protective colloid, and a gel protective film is formed on the surface of the colored particles through the charge action between the sheets. However, since the synthesized nano-layered silicate gel is a physically cross-linked gel, the...

Problems solved by technology

The colorful coatings prepared by this method are cheap, but the protective colloid that does not participate in the reaction in the dispersed phase will affect the water resistance of the dried paint film, and the metal ions that do not participate in the gel reaction in the continuous phase will also affect the stability of the system. Adverse effect, causing bleeding and post-thickening

[0003] Existing coatings have poor high temperature resistance and are easy to fall off under high temperature conditions. Therefore, the present invention proposes organic-inorganic composite colorful coatings
