Problems solved by technology

During the natural formation of deposition for many years, there are organic substances, carbonates and other impurities in the original pores and cavities to block the channels, and there will be some zeolite water and metals adsorbed for charge balance and ion exchange between the molecular lattices. Cations, block water molecules from entering, reduce adsorption capacity

Abstract

The invention relates to a modified zeolite powder inorganic environment-friendly building coating and a preparation method thereof. The modified zeolite powder inorganic environment-friendly building coating comprises the following components in percentage by weight: 15%-20% of light calcined magnesia powder, 5%-10% of magnesium sulfate heptahydrate, 35%-45% of modified zeolite powder, 20%-25% of water, 10%-15% of heavy calcium carbonate, 0.5%-1.0% of an additive, 0.3%-0.5% of fibers, 0.3%-0.5% of hydroxypropyl methyl cellulose and 0.3%-0.5% of redispersible rubber powder. The modified zeolite powder and the low-quality light calcined magnesia are adopted as main raw materials to prepare the inorganic environment-friendly building coating, a base material is an inorganic cementing material, and the inorganic environment-friendly building coating does not contain an organic solvent, does not contain formaldehyde, does not mildew and does not pollute the environment and has the advantages of being good in construction performance, high in bonding strength, fireproof, capable of adsorbing formaldehyde and capable of adjusting indoor humidity.

Description

technical field [0001] The invention relates to the technical field of architectural decorative coatings, in particular to a modified zeolite powder inorganic environmental protection architectural coating and a preparation method thereof. Background technique [0002] With the rapid development of residential construction, people's pursuit of a comfortable living environment has greatly stimulated the promotion and application of various architectural coatings. At the same time, the development of the paint industry has also brought environmental pollution problems. Since most paints contain volatile organic solvents, volatile organic compounds, free formaldehyde, soluble lead, cadmium, chromium and mercury will be generated during construction and use. Heavy metals, as well as harmful substances such as benzene, toluene, and xylene, cause air quality to decline and affect human health. Nowadays, the whole world is advocating green environmental protection and sustainable ...
