Abstract

The invention discloses a method for preparing a thermal-resistant dampproof modified sodium silicate building coating and belongs to the technical field of building coatings. The method comprises the following steps: (1) preparing sodium fluosilicate modified sodium silicate; (2) uniformly mixing the sodium fluosilicate modified sodium silicate, aluminum oxide, zirconium oxide, ferric oxide, copper sulfate, calcium oxide, boric oxide, marble dregs, high-alumina cement and an organic silicon resin, putting into a platinum-rhodium crucible, and melting for 12 hours at 400 DEG C; (3) uniformly mixing the molten liquid with nano TiO2 ceramic powder and nano Si3N4 ceramic powder, and stirring and continuously melting by using stirring equipment; (4) soaking fish glue into water, leaving to stand, taking out after the fish glue is saturated and swelled, and heating to obtain a colloid; (5) uniformly mixing ammonium hydroxide with ethanol, performing water-bath heating, injecting into the colloidal fish glue, and completely stirring and mixing with the molten solution prepared in the step (3), thereby finally obtaining the coating. The product prepared by using the method has the advantages of being relatively good in water resistance, thermal resistance, acid resistance, aging resistance and the like, and is high in adhesion property and coating hardness when being compared with a similar product.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a preparation method of a heat-resistant and moisture-proof modified water glass architectural coating. Background technique [0002] The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." [0003] Driven by downstream industries, China's coatings industry is growing day by day, and architectural coatings, one of its branches, have also achieved considerable development. Statistics show that in 2011, the total output of China's architectural coatings was about 3.5182 million tons, an increase of more than ...
