A kind of easy-to-clean nano antifouling and antibacterial coating and preparation method thereof

Abstract

The invention discloses an easy-to-clean nano antifouling antibacterial paint and a preparation method thereof. The paint comprises the following raw materials by weight: 2-20 parts of nano titanium dioxide, 5-20 parts of bentonite, 3-8 parts of silica aerogel, 0.5-20 parts of modified rare earth, 5-20 parts of nano graphene, 5-20 parts of isophorone, 1-20 parts of diacetone alcohol, 1-10 parts ofan antifoulant, 6-20 parts of modified organic silicon resin, 2-20 parts of ethylene glycol butyl ether / propylene glycol butyl ether, and 6-30 parts of butyl acetate. The modified rare earth is modified nano cerium oxide and nano lanthanum oxide in a weight ratio of 0.35:1, and a titanate coupling agent is employed for modification treatment of nano cerium oxide and lanthanum oxide, the modifiedrare earth has a particle size of 1-100nm, and the nano graphene has a particle size of 3-5nm. The paint prepared by the technical scheme adopted by the invention can achieve the following effects after application to a substrate surface: 1. good anti-fouling effect; 2. easy cleaning; 3. good antibacterial effect; 4. strong adhesion; and 5. high hardness.

Description

technical field [0001] The invention relates to an antibacterial coating, in particular to an easy-to-clean nano antifouling antibacterial coating and a preparation method thereof. Background technique [0002] In daily life, the cleanliness of the home environment is getting more and more attention. In the residence, the kitchen, bathroom and other spaces, as well as the products used in the above-mentioned spaces and various household appliances and operating surfaces are undoubtedly the most vulnerable places to be polluted, because the temperature, humidity, pH, etc. of the above-mentioned spaces are more obvious. Changes, resulting in problems such as roughness, staining, aging, and cracking on the surface of the product or operating surface, and bacteria and viruses are more likely to adhere to it. Simultaneously, it is also very difficult to clean the above-mentioned space and the surface of the product. When the surface is severely damaged, replacement is inevitable...
