Abstract

The invention relates to an organic-inorganic composite paint, and a preparation method and application thereof. The organic-inorganic composite paint comprises a basic paint and an organic silicon resin in a volume ratio of 1:(0.5-2); and the basic paint comprises the following components in percentage by volume: 10-20% of pH regulator, 0.001-0.5% of functional catalyst and the balance of siloxane composition. The preparation method comprises the following step: mixing the basic paint and organic silicon resin to obtain the organic-inorganic composite paint. The invention uses diphenyldimethoxysiloxane as one of siloxane components in the paint for the first time, and the diphenyldimethoxysiloxane can enhance the gloss of the paint, so that the prepared paint has high gloss; the main effect of the diphenyldimethoxysiloxane is not the same as the conventional siloxane; and the diphenyldimethoxysiloxane enhances the orientation capacity, heat resistance and oxidation resistance of the system, strengthens the water repellency, improves the thermoelasticity and also improves the compatibility with organic resin and mutualsolubility with pigment. The organic-inorganic composite paint has the advantages of favorable adhesiveness for various substances and high storage stability.

Description

【Technical field】 [0001] The invention relates to the technical field of functional coatings, in particular to an organic-inorganic composite coating and its preparation method and application. 【Background technique】 [0002] The particle size of the pigment in the paint and its dispersibility in the base material will affect the gloss of the paint film. The finer the pigment fineness, the better the uniformity of dispersion in the base material, which helps to form a flat and smooth paint film. The pigment-to-base ratio in the paint affects the gloss of the paint film. The gloss decreases due to the weakening of the specular reflection by the pigment particles in the paint film, and the gloss gradually decreases with the increase of the pigment volume concentration (P.V.C). When the pigment-base ratio is constant, the greater the oil absorption of the pigment, the lower the gloss. Different colors of pigments have different degrees of light absorption and reflection.
