Water-based inorganic mineral composite terrace coating and preparation method thereof

Abstract

The invention relates to a water-based inorganic mineral composite terrace coating. The coating comprises primer, finish paint and varnish from bottom to top, potassium silicate liquid is used as a base material; silicon dioxide is used as a main raw material, the water-based inorganic mineral composite coating is natural and environment-friendly, has fireproof and flame-retardant characteristics,is combined with mineral matrixes such as cement to generate a petrochemical effect, is modified by adding the hydrophobic agent into a thickening agent, improves the construction performance and thewater resistance of the coating, resists acid, alkali and salt mist, does not fall off, and is suitable for wide weather conditions. The preparation method of the coating is simple and efficient, andthe obtained coating system is complete.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based inorganic mineral composite floor coating and a preparation method of the coating. Background technique [0002] At present, the commonly used floor coatings in China use epoxy resin raw materials as the main agent, add pigments, solvents, and auxiliary curing agents after deployment. According to different dispersion media, they can be divided into solvent-based, solvent-free and water-based epoxy resins. Floor coatings. The disadvantage of solvent-based epoxy resin coatings is that the volatile organic solvents contained in them will cause harm to the human body and the environment, and they are flammable and explosive; the disadvantages of solvent-free epoxy resin coatings are that the coating film is very dense and has poor air permeability , easy to cause coating film bulging, peeling off, etc.; although water-based epoxy resin coating does not co...

Problems solved by technology

The disadvantage of solvent-based epoxy resin coatings is that the volatile organic solvents contained in them will cause harm to the human body and the environment, and they are flammable and explosive; the disadvantages of solvent-free epoxy resin coatings are that the coating film is very dense and has poor air permeability , easy to cause coating film bulging, peeling off, etc.; although water-based epoxy resin coating does not contain organic solvents or has low content of volatile organic compounds, it has little environmental pollution and good air permeability, which solves the problems of the above two coatings, but Because water and oil are not compatible, when it is applied to the floor of industrial workshops such as instruments and meters and machinery manufacturing that are often eroded by various oils, it has poor wetting effect on such floors, poor adhesion, and wear resistance does not meet the requirements. And other issues

The mineral floor coating of this technical scheme has strong fire and flame retardancy and good wear resistance, but there are still deficiencies in weather resistance and salt spray resistance.

[0006] In summary, the prior art still lacks a kind of inorganic mineral composite floor coating with strong fireproof and flame retardant, acid and alkali resistance, salt spray resistance and weather resistance.
