Description
Technical field
The present invention relates to rain-proof membrane coat technical field more particularly to a kind of self-cleaning anti-fog coatings of rain-proof film.
Background technique
Rain-proof film is called self-cleaning antifog film, because its performance is water droplet, the rapid beach on rain-proof film is opened, and is called hydrophilic
Film, because beach is opened there is other title anti-extension moisture film or, being used primarily on automobile rearview mirror so again at present rapidly
It is rain-proof film.Because its principle is hydrophily being called antifog film, the principle of antifog film is exactly hydrophily, physical principle
It is exactly that hydrophilic substance coating makes its tension become larger on the surface of the material, allows water droplet drop to be stretched rapidly on the surface of the material, keep droplet flat
Graduation.
But existing rain-proof film will appear raindrop in the rainy day and hang on automobile rearview mirror, cause rearview mirror sight mould
Paste, can not check vehicle rear situation by rearview mirror, increasingly obscure if not eliminating and will result in glass, will affect when serious
Traffic safety can be created great difficulties to driver and passenger and be endangered with life.Therefore, we have proposed a kind of rain-proof film from
Clean anti-fog coating is for solving the above problems.
Summary of the invention
The purpose of the present invention is to solve existing rain-proof film exists in the prior art will appear raindrop in the rainy day to hang
On automobile rearview mirror, the shortcomings that causing rearview mirror blurred vision, and a kind of self-cleaning anti-fog coating of the rain-proof film proposed.
A kind of self-cleaning anti-fog coating of rain-proof film, the raw material including following parts by weight: 92~95 parts of acrylic Acid UV resin, right
