Problems solved by technology

The above coatings have the characteristics of heat insulation, waterproof and anti-fouling, etc., but due to the limitation of the composition of the coatings, the existing coatings generally can only play a part of them.
With the increasing requirements of architectural coatings, it is difficult to meet the demand only by existing coatings
However, there is no report on the patent of strontium aluminate nanosheet composite coating

Abstract

The invention discloses a strontium aluminate nano-sheet composite coating, and belongs to the technical field of chemical engineering. The strontium aluminate nano-sheet composite coating comprises the following components in percentage by mass: 20-35 percent of strontium aluminate nano-sheets, 5-15 percent of nano zirconia, 10-20 percent of ethenyl ethanoate-ethylene copolymer emulsion, 5-10 percent of styrene acrylate co-polymer emulsion, 3-8 percent of propylene glycol butyl ether, 3-8 percent of hydroxyl silicone oil emulsion, 20-35 percent of water, 1-3 percent of polyvinyl alcohol, 0.2-1 percent of polyoxyethylene, 0.1-1 percent of dimethyl sulfoxide, 0.05-0.2 percent of polydimethylsiloxane, 0.5-3 percent of isopropanol, and 0.1-0.5 percent of polyether-modified dimethyl polysiloxane co-polymer emulsion. The strontium aluminate nano-sheet composite coating is stable in performance, and has multiple functions of corrosion resistance, flame retardance, mould prevention, antibacteria, anti-fouling property, waterproof property, heat preservation and the like, and has good application prospect on coatings in buildings and equipment.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a strontium aluminate nanosheet composite coating. Background technique [0002] Paint is a kind of coating on the surface of the object to be protected, such as the surface of the inner and outer walls of the building, forming a continuous protective layer firmly attached to the surface of the object to achieve the purpose of decoration and protection. Solvent-based coatings will release a large amount of volatile organic compound (VOC) gas after spraying, which will seriously endanger human health and pollute the environment. With the enhancement of people's awareness of environmental protection, the environmental protection requirements for the interior and exterior wall coatings of buildings are also constantly increasing. Using water instead of organic solvents to develop water-based coatings has the characteristics of safety and no pollution, and has ...
