Abstract

The invention discloses an anti-fog film. The anti-fog film comprises the following components in parts by weight: 20-40 parts of methyl acetate, 5-10 parts of titanium dioxide, 2-5 parts of metal silver powder, 5-8 parts of sodium carboxymethyl cellulose, 6-11 parts of tin oxide, 4-8 parts of propylene glycol butyl ether, 12-17 parts of nano-zirconia sol, 5-8 parts of sodium amide, 4-8 parts of zinc acetate dihydrate, 2-5 parts of chitosan, 2-5 parts of fluoroethylene carbonate, 0.1-1 part of copper selenate, 0.1-1 part of acrylic resin film-forming agent, and 0.1-1 part of antioxidant. The anti-fog film can significantly reduce the haze, effectively improve light transmittance, has wide application, and has a better social value; and meanwhile, the preparation method of the anti-fog filmis simple, and is low in process conditions, so that realization of industrial production is facilitated.

Description

technical field [0001] The invention relates to a plastic material, in particular to an anti-fog film and a preparation method thereof. Background technique [0002] Mirrors (English glasses) are commonly used daily necessities in people's daily life. There are two types of mirrors: flat mirrors and curved mirrors. Flat mirrors are often used by people to organize their appearance. Curved mirrors are also divided into concave mirrors and convex mirrors. Mirrors, furniture accessories, architectural decorations, optical instrument components and solar cookers, reflectors for car lights and searchlights, reflecting telescopes, car rearview mirrors, etc. Traditional flat mirrors are prone to fogging, which seriously affects people's use experience. Although there is a device for heating and drying the mirror to remove water mist, further operations such as wiping are required, which is very troublesome. Therefore, the present invention provides an anti-fog film and a preparati...
