Abstract

The invention relates to a preparation method of a water-borne inorganic paint and a method for preparation of an inorganic coating from the water-borne inorganic paint. The method is characterized by including the preparation steps of: firstly dispersing metal silicate in silica sol to obtain a silicate silica sol solution; then adding a trimethoxy silane mixture into water, stirring the substances evenly, then adding an inorganic acidic catalyst, further stirring the substances evenly to obtain an organosilicon prepolymer solution; finally mixing the silicate silica sol solution with the organosilicon prepolymer solution, then adding a film-forming assistant, a leveling agent and a defoaming agent, and stirring the substances evenly to obtain the water-borne inorganic paint; and adding a proper amount of water into the inorganic paint to obtain an inorganic paint's diluent solution with a solid content of 10%-30%, brushing or spraying the diluent solution to a matrix surface, and performing natural drying, thus obtaining an inorganic transparent coating. The strength and toughness of the coating are improved, and the water-borne inorganic paint has the advantages of good hydrophobic, waterproof and anti-mildew effects, etc.

Description

technical field [0001] The present invention relates to a kind of preparation method of water-based inorganic paint and preparation method of water-based inorganic paint [0002] Coating method. Background technique [0003] Compared with the currently widely used organic-based architectural coatings (emulsion paint, etc.), it has the following advantages: 1. Petrification: Inorganic coatings can react with mineral substrates to form a waterproof and acid-resistant silicon 2. Non-combustibility: Inorganic coatings have the characteristics of inorganic substances, and their temperature resistance is particularly good. Not only will they not burn at a high temperature of 1200 ° C, but they are also flame-retardant; 3. Breathability : Inorganic coatings are waterproof and highly breathable, so that the water inside the stone building can evaporate freely; at the same time, it has the filtering effect of alkali substances, which can prevent the coating from bubbles, thermal bur...
