Problems solved by technology

Waterproof coatings can not only play an aesthetic role, but also effectively protect building materials. However, once the general waterproof coating encounters oil stains, it is difficult to clean. Forcible cleaning will damage the membrane surface, and the coating needs to be repainted.

Embodiment 1

[0019] Mix and stir 35 parts of propylene emulsion, 5 parts of kaolin, 3 parts of diatomaceous earth, 5 parts of talc, and 20 parts of glycerol solution, and irradiate with ultraviolet rays;

[0020] Mix the obtained material with 10 parts of acrylic acid solution, and send it into a high-pressure heating furnace with the temperature set at 130°C and the time set at 45 minutes;

[0021] Put the obtained material into a cracking kettle preheated to 150°C, add 5 parts of hollow glass microspheres, 10 parts of paraffin oil and start the stirring device at a stirring speed of 250r / min, adjust the temperature to 160°C, and heat for 30 minutes. The obtained modified material;

[0022] Add the ceramic fiber to 10 parts of sodium hydroxide solution and stir evenly for 30 minutes. After the stirring is over, centrifuge 10 parts of the ceramic fiber through a centrifuge, take the precipitate and wash it with water until it is neutral. The ceramic fibers are freeze-dried, and the freeze...

Abstract

The invention provides a nano antifouling paint and a preparation method thereof, which relate to the field of paint. Prepared from the following raw materials by weight: 35-45 parts of propylene emulsion, 5-10 parts of kaolin, 3-5 parts of diatomaceous earth, 5-8 parts of talcum powder, 5-10 parts of ceramic fiber, 3-5 parts of hollow glass Microspheres, 5-10 parts of paraffin oil, 20-30 parts of glycerin solution, 5-10 parts of sodium hydroxide solution, 5-8 parts of coalescent, 10-15 parts of acrylic acid. The invention provides a nano antifouling paint and a preparation method thereof, which can make the prepared paint have better oil repellency, thereby achieving antifouling effect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a nano antifouling coating and a preparation method thereof. Background technique [0002] Architectural waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reaction curing. . Waterproof coatings can not only play an aesthetic role, but also effectively protect building materials. However, once the general waterproof coating encounters oil stains, it is difficult to clean. Forcible cleaning will damage the membrane surface, so that the coating needs to be repainted. Contents of the invention [0003] The object of the present invention is to provide a kind of nano antifouling paint and preparation method thereof, to solve the above-mentioned technical problems. [0004] In order to...
