Abstract

The invention discloses waterproof self-cleaning silicone resin coating. The coating is prepared from the following raw materials in parts by weight: 20 to 30 parts of polymethylphenyl organic siliconresin, 15 to 18 parts of fluoroalkyl silane, 5 to 7 parts of a silane coupling agent, 2 to 7 parts of nanometer titania, 6 to 10 parts of palygorskite, 8 to 12 parts of carbon fiber, 8 to 12 parts ofnanometer calcium carbonate, 10 to 15 parts of kaolinite, 3 to 8 parts of carbon nanometer tube, 25 to 35 parts of softened water, 2 to 5 parts of a thickening agent, 2 to 7 parts of a dispersing agent, 2 to 6 parts of a water repellent agent, and 1 to 3 parts of a coalescing agent. The coating formed by the polymethylphenyl organic silicon resin, the fluoroalkyl silane and the silane coupling agent is good in waterproof effect. The added nanometer titania ensures that the coating has a self-cleaning function, and meanwhile is matched with the palygorskite, carbon fiber, nanometer calcium carbonate and kaolinite, the curing density is extremely high, the surface smoothness is extremely high, dust in the air cannot be adhered to the surface of the coating, and the aesthetic degree is good.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a waterproof self-cleaning silicone resin coating and a preparation method thereof. Background technique [0002] Paint is a kind of liquid or fixed material that is coated on the surface of an object and forms a thin film under certain conditions to play a protective, decorative and specific role. It has been widely used in daily life. With the development of industry, the variety of coatings is increasing day by day, and the quality and performance are constantly improving. The simple protection of coatings can no longer meet people's requirements. Especially in people's daily life, waterproof and moisture-proof are getting more and more attention. [0003] Waterproof coating refers to a kind of coating that the coating film formed by coating can prevent rainwater or groundwater from seeping. The waterproof film formed after the waterproof coating is cured has certain extensibility, e...
