Problems solved by technology

[0004] However, whether it is an organic water-based emulsion coating or an inorganic polymer coating, there are certain disadvantages in the performance. For example, the organic water-based emulsion coating uses a large amount of organic resin materials in the preparation process as a base material, and naturally cannot avoid organic materials. Defects such as easy aging, poor stain resistance, poor heat resistance, and easy to mold and rot; while inorganic-based coatings based on inorganic polymer materials can avoid the performance defects of organic water-based emulsion coatings. It has low VOC , aging resistance, fire prevention and mildew resistance, high temperature resistance, air permeability and water resistance, and good stain resistance, but this type of coating also has the performance disadvantages of hardening and brittleness after its own film formation

Abstract

The invention relates to an organic-inorganic composite paint and a preparation method thereof. The organic-inorganic composite paint is prepared from the following components in parts by weight: water, a dispersing agent, a defoaming agent, titanium dioxide, a filling material, an emulsion, water glass, an antifreezing agent, and a thickening agent, wherein the filling material is one or any combinations of heavy calcium carbonate, barite and water-washed soil; the emulsion is the copolymer of styrene and a crylic acid. The organic-inorganic composite paint prepared by the preparation method disclosed by the invention not only has excellent flexibility, but also has the properties of water resistance, alkali resistance and stain resistance.

Description

technical field [0001] The invention relates to a kind of coating for building, in particular to an organic-inorganic composite coating and a preparation method thereof. Background technique [0002] Organic architectural coatings can be divided into solvent-based coatings and water-based coatings (including water-soluble coatings and emulsion coatings) according to the dispersion medium used. Among them, the coatings that use water as a solvent are most commonly used by consumers because of their health, environmental protection and convenient construction. They are based on resin materials and are called organic water-based emulsion or aqueous solution coatings. For example, polyvinyl acetate emulsion, polystyrene acrylic emulsion, pure polyacrylic acid emulsion and chlorine partial emulsion, etc. [0003] Inorganic architectural coatings are mainly inorganic polymer coatings, including water-soluble silicate (alkali metal silicate), silica sol, organic silicon and inorga...
