Abstract
The invention discloses a metal surface hardness easy-to-clean antibacterial vehicle shield and a preparation method thereof, and relates to the technical field of nano coatings. The coating comprises the following raw materials in parts by weight: 1-5 parts of a self-cleaning nano additive, 12-18 parts of hydrogen-containing silicon resin, 0.1-0.3 part of a catalyst, 12-18 parts of nano siloxane, 35-45 parts of methyl cyclohexane, 8-12 parts of an environment-friendly flux, 3-8 parts of a silicon-containing surface additive, 3-8 parts of nano silver and 0.5-3 parts of graphene. The method comprises the following steps: modifying the hydrogen-containing silicon resin, mixing the modified hydrogen-containing silicon resin, an environment-friendly flux, nano siloxane, methyl cyclohexane and a self-cleaning nano additive, putting the mixture into a high-pressure kettle, mixing, stirring and cooling to room temperature to obtain the antibacterial shield. The components are green and environment-friendly, the coating has excellent acid resistance, alkali resistance, antibacterial performance and mechanical strength, the preparation method is simple, convenient and easy to repeat, and the coating is suitable for being used as a coating on metal surfaces of automobiles, machines and equipment.
Description
technical field [0001] The invention belongs to the technical field of nano coatings, in particular to an antibacterial car shield with a hard metal surface and an easy-to-clean antibacterial vehicle shield and a preparation method thereof. Background technique [0002] Automobile bodies and parts are basically made of metal or metal with a coating on the surface. In order to ensure the hardness and quality requirements of the body or these parts, the body or these parts themselves are hard metal materials. [0003] With the rise of the auto beauty industry, methods such as coating and attaching car covers to the surface of cars or auto parts are becoming more and more popular. Auto parts include wheel hubs, front bumpers, etc.; Plating or vacuum coating technology is used to modify the surface of the automobile wheel hub, but these traditional modification technologies require the use of a large amount of plating solution, which causes environmental chemical pollution.
