Description
Technical field
The present invention relates to glass frost-proof technical field of membrane, more particularly to a kind of vehicle glass anti-fog film.
Background technology
Since northern winter temperature is relatively low, one layer of thicker frost, people can be formed on the windshield by being parked in the automobile of outdoor
Work defrosting is time-consuming and laborious.Therefore a thin layer film can be adsorbed outside windshield, can stops that frost is formed in glass surface,
Film need only be removed before traveling.
The content of the invention
The technical problems to be solved by the invention are white time-consuming and laborious on artificial removing windshield, there is provided a kind of
PVC vehicle glass anti-fog films.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of PVC vehicle glasses anti-fog film, it is characterised in that：The quality proportioning of each component is：
Further, the degree of polymerization of the PVC paste resin is 1200~1900.
Further, the degree of polymerization of the chlorine vinegar paste resin is 900~1800.
Further, the calcium powder is nano-calcium carbonate.
The preparation method of above-mentioned anti-fog film：Raw material is taken according to said ratio, is stirred into thickener, deaeration is ground through vacuum
Afterwards, the thickener is formed 200-300 μ m thicks in release liners by blade coating, be then plasticized 200-220 at 210-230 DEG C
Second.
A kind of PVC vehicle glasses anti-fog film provided by the invention and preparation method thereof, obtained anti-fog film can be adsorbed
Windshield surface, prevents frost from being formed directly on windshield, and winter will not freeze onto glass.By direct
Remove anti-fog film and reach defrosting effect, and can be with Reusability.
Embodiment
A kind of PVC vehicle glasses anti-fog film, the quality proportioning of each component are：
The degree of polymerization of the PVC paste resin is 1200~1900.The chlorine vinegar paste resin is vinyl chloride vinyl acetate

Select Environment-friendlycalcium calcium zinc stabilizer.The calcium powder is nano-calcium carbonate.
PVC paste resin mixes the shaping of plasticization at a certain temperature with plasticizer, and plasticizer adds resin plastic
Property, vinyl chloride-vinyl acetate interpolymer paste resin plays the role of reducing plasticization temperature, and calcium zinc stabilizer prevents polyvinyl chloride tree
Fat, which decomposes, makes product turn yellow, and nano-calcium carbonate improves product hardness.By the reasonable selection and proportioning of said components, make anti-fog film
Tensile strength it is good, elongation at break is excellent.
The preparation method of above-mentioned anti-fog film：Raw material is taken according to said ratio, is stirred into thickener, deaeration is ground through vacuum
Afterwards, the thickener is made to form 200-300 μ m thicks in release liners by blade coating, preferred thickness is 250 μm, then in 210-
It is plasticized 200-220 seconds at 230 DEG C.
Prepared PVC vehicle glass anti-fog films, can adsorb on windshield surface, prevent frost from directly being formed
On windshield, reach defrosting effect by directly removing anti-fog film, and can be with Reusability.
