Novel environment-friendly waterborne inorganic paint and preparation method thereof

Abstract

The invention discloses novel environment-friendly waterborne inorganic paint and a preparation method thereof. The novel environment-friendly waterborne inorganic paint is prepared from, by weight, 55-65 parts of kaolin, 12-20 parts of sodium silicate, 20-30 parts of titanium dioxide, 1-5 parts of nano zinc oxide, 5-10 parts of ultrafine wollastonite powder, 1-10 parts of nano calcium carbonate, 1-5 parts of ultrafine white mica powder, 7-15 parts of polyvinyl alcohol, 1-4 parts of ultrafine molybdenum disulfide powder, 2-10 parts of nano silicon dioxide, 2-12 parts of nano magnesium oxide, 2-12 parts of nano aluminum oxide, 1-3 parts of magnesium chloride, 1-3 parts of a sodium silicate hardening accelerator, 2-5 parts of a pH value regulating agent, 1-8 parts of a waterproof agent, 6-10 parts of an antifoaming leveling agent, 1-3 parts of a thickening anti-settling agent and 280-310 parts of water. The novel environment-friendly waterborne inorganic paint which is environment-friendly waterborne inorganic paint for buildings is high in storage stability, excellent in water resistance and alkali resistance, strong in adhesion, high in fire resistance, high in strength and hardness, resistant to scratching and contamination, excellent in corrosion resistance and antibacterial property, free of formaldehyde, benzene compounds, VOC (volatile organic compounds) and heavy metal elements, completely environmental friendly and nontoxic, suitable for industrial production, easy for painting and convenient and quick in construction.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a novel environment-friendly water-based inorganic coating and a preparation method thereof. Background technique [0002] At present, most of the coatings used for interior decoration are latex paints. Latex paints are mainly a large class of synthetic resin emulsion paints with acrylate copolymer resin emulsion as base material and water as dispersant. Although this type of polymeric resin itself is safe and non-toxic, some unpolymerized volatile toxic free monomers and various organic additives remaining in the resin will still pollute the indoor air and cause harm to human health. With the continuous enhancement of people's awareness of health and environmental protection, the environmental protection requirements for interior decoration coatings are also getting higher and higher. In addition, the synthetic resin emulsion raw materials are all derived from limited petroleum resource...

AI Technical Summary

Problems solved by technology

Water-based inorganic coatings use silicate (mainly sodium silicate) aqueous solution as the binder between inorganic substances. This type of coating has strong binding force, high strength, good alkali resistance and heat resistance, but the water resistance of sodium silicate binder poor performance, which reduces the service life of the coating and greatly restricts its large-scale application in the field of architectural coatings
