High-temperature-resistant anti-corrosion potassium silicate coating and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant anti-corrosion potassium silicate coating which is prepared from the following four components in percentage by weight: a high-temperature-resistant solute, an anti-corrosion solute, a coupling solvent and a blending solvent, wherein the high-temperature-resistant solute is composed of the following components: 10-15% of epoxy resin, 8-17% of palm oil, 2.3-4.5% of precipitated barium sulfate, 5.7-9.2% of quartz stone powder, 3.2-6.8% of butyl acetate, 12-18.4% of asbestos powder, 12-19.5% of methylhydrosiloxane and 11-15.7% of organic soil.The anti-corrosion solute is prepared from the following components: 28.7-36.2% of fluorine-containing emulsion with rust, 8-12.5% of talcum powder, 3.8-9% of high titanium powder, 7-10% of waterborneepoxy emulsion, 4.5-6.3% of high chlorinated polyethylene resin, 4.3-5.9% of organosiloxane and 12-16.5% of diatomite; the coupling solvent is prepared from the following components: 40-46 percent ofpotassium silicate solution, 10-13.6 percent of silane coupling agent, 1.5-2 percent of defoamer, 1.2-1.5 percent of wetting agent and 1.8-2.3 percent of leveling agent; the blending solvent is composed of the following components: 1%-2% of a bactericide, and 10-14% of water, a potassium silicate solution which is good in viscosity and is used as a main component improves the stability of the whole coating, and the viscosity and adhesive force of each component are enhanced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-temperature-resistant and anti-corrosion potassium silicate coating and a preparation method thereof. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The effect of coating can be summarized into three aspects: protective effect, decorative effect, special functional effect. The general composition of coatings: including film-forming substances, pigments and fillers, solvents, and additives. Coatings are one of the indispensable materials for the development of the national economy. Due to the many special functions of coatings, there ar...
