Abstract

The invention relates to an all-in-one water-borne inorganic-organic hybrid architectural coating and a preparation method thereof, wherein the all-in-one water-borne inorganic-organic hybrid architectural coating is prepared by taking a compounded product of a water-borne inorganic film-forming matter and an organic polymer emulsion as a base material through the steps of adding various pigments / fillers and auxiliaries into the base material, then carrying out beating, grinding and paint mixing on the obtained mixture. In the invention, through a Si-O-Si polymer net structure which can be formed by compounding alkali metal silicates and small-particle-size silica sols in the process of film forming, the early water resistance of a paint film is greatly increased, and the eventual hardness, scraping resistance and stain resistance of the paint film are greatly increased; and through adding the organic polymer emulsion, the film-forming performance of the coating can be improved, and the defects that the traditional two-component inorganic coating is easy to crack, bad in decorative properties, poor in storage stability, and the like are overcome. The coating prepared by using the method disclosed by the invention has various functions of environmental friendliness, non-toxicity, thermal insulation, ultra scrubbing resistance, abrasion resistance, yellowing resistance, ageing resistance, fouling resistance, good air permeability, sound insulation, and the like.

Description

technical field [0001] The invention relates to the field of latex paints for interior and exterior walls, in particular to inorganic high molecular polymers, and in particular to inorganic-organic hybrid paints. Background technique [0002] Water-based inorganic coatings have attracted widespread attention due to their high hardness, excellent weather resistance, stain resistance, good air permeability, long-term heat resistance and environmental friendliness. Nowadays, "four E" (Ecomomy, Efficiency, Energy, Ecology, that is, economy, high efficiency, energy saving, and ecology) has become the basic principle followed by human development, and the raw materials used in inorganic coatings come directly from nature, with abundant sources and low prices. Therefore, inorganic coatings have broad market prospects. [0003] According to the types of film-forming substances, water-based inorganic coatings can be divided into three categories: alkali metal silicate coatings, sili...
