Technical field
The present invention relates to a kind of fog-proof adhesive films, more particularly, to a kind of fog-proof adhesive film and its preparation method and application.
Background technique
The design of motorcycle helmet mask is to provide wide visual field for bicyclist, however, passing through during routine use
The problem of mask hazes can often be encountered, especially in rainy day or winter, due to inside and outside mask there are certain temperature difference,
The hot-air of mask internal body exhalation is easy to condense into droplet in mask inner surface, thus the phenomenon that hazes.At present
In the market common faceplate not can avoid the problem that hazes in cold environment, there are biggish security risks.
In the prior art by changing the structure design of mask, using gap between mask and the brim of a hat by the gas of mask exterior
Stream is guided to the inside of mask, to reduce the temperature difference existing for mask surfaces externally and internally, and then prevents mask inner surface that fogging occurs,
Prevent user unsighted.However, in the actual use process, the anti-fog effect of the invention is not obvious, especially exist
In the environment of winter cold, mask internal-external temperature difference is larger, and in warming demand, the outer gas stream opposite cover inner surface of introducing is formed
Droplet defogging effect it is poor, be unable to satisfy use demand.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of fog-proof adhesive films and its preparation method and application.According to
One aspect of the present invention, provides a kind of preparation method of fog-proof adhesive film, comprising: anti-fog coating is dispersed in solvent
