Problems solved by technology

However, during driving, due to the difference between the specific heat of the glass and the specific heat of the air, fogging often occurs, which seriously affects the sight of the driver and passengers.
At the same time, the existing car defogging is mainly through blowing and heating. After the fog appears, it needs to be dealt with in time, otherwise it will aff

Abstract

The invention relates to an antifogging film material and a preparation method thereof. The antifogging film material is prepared from the following components in parts by weight: 68-85 parts of ethyl acetate, 8-11 parts of cellulose acetate butyrate, 0.5-2 parts of benzoperoxide, 0.5-1.5 parts of blue copperas, 0.1-0.4 part of sodium zirconate, 0.02-0.8 part of boron trifluoride-dimethylaniline and 0.02-0.5 part of cobalt oxide. The invention also relates to a preparation method of the antifogging film material.

Description

technical field [0001] The invention belongs to the field of film materials, in particular to an anti-fog film material and a preparation method thereof. Background technique [0002] A film is a thin, flexible, transparent sheet, usually made of plastic, adhesive, rubber, or other materials. Commonly used film materials mainly include optical film, composite film, superconducting film, polyester film, nylon film, plastic film, etc. [0003] Automobiles have become more and more important means of transportation in people's lives. The glass used on automobiles is generally ordinary glass. Although ordinary glass has good light transmittance, it is convenient to observe the situation outside the car. However, during driving, due to the difference between the specific heat of the glass and the specific heat of the air, fogging often occurs, which seriously affects the sight of the driver and passengers. At the same time, the existing automobile defogging is mainly through bl...
