Heat-insulation fireproof water-based paint and preparation method thereof

Abstract

The invention discloses a heat-insulation fireproof water-based paint. The invention is characterized in that the paint is prepared from the following raw materials in parts by weight: 20-25 parts of silicone-acrylic emulsion, 1-2 parts of aluminum potassium sulfate, 1-2 parts of polyethyleneglycol, 2-4 parts of barite powder, 14-18 parts of silica sol, 20-25 parts of water-based polyurethane, 0.3-0.5 part of sodium caseinate, 2-4 parts of propanediol tert-butyl ether, 1-2 parts of benzotriazole, 1-2 parts of dioctyl adipate, 0.2-0.4 part of mineral oil defoaming agent, 1-2 parts of aluminum tripolyphosphate, 1-2 parts of potassium methylsilanolate, 2-3 parts of borax, 2-3 parts of water glass, 1-2 parts of trisodium phosphate, 2-3 parts of pulverized asbestos, 7-9 parts of heat-insulation slurry, 2-3 parts of carbon fiber and 14-20 parts of deionized water. The paint has excellent fire resistance, heat-insulation property, aging resistance, water resistance and the like. The added silica sol enhances the hardness and wear resistance of the paint film. By using the safe and nontoxic raw materials and using water as the diluter, the paint has the advantages of low cost and low VOC (volatile organic compound) value, is free of heavy metals and benzene organic solvents, is convenient for construction and application and harmless to the body of the workers, has wide application range, and is worthy of popularization.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a heat-insulating fireproof water-based paint and a preparation method thereof. Background technique [0002] With the consumption of available energy, energy-saving materials have attracted widespread attention from humans, especially from researchers. Heat-insulating coating is a new type of energy-saving material developed in recent years. It effectively reflects the energy of sunlight and reduces the absorption of solar radiation energy by the surface of objects, thereby achieving the effect of heat insulation. Heat insulation coating, as a functional coating, has the characteristics of reducing the surface temperature of objects, preventing heat conduction, improving the working environment, and improving safety. Water-based paint is a kind of paint that uses emulsion as a binder, adds film-forming aids, thickeners, dispersants, defoamers, pigments and fillers and...

Problems solved by technology

However, some harmful substances are added to the existing fireproof coatings, such as chlorinated paraffin, which will produce halogen gas harmful to the human body after the combustion process, which has potential safety hazards, is not conducive to environmental protection, and has poor flame retardant effect.
