Antifog thermal isolation film
Technical field
The present invention relates to a kind of thermal isolation film, particularly the antifog thermal isolation film of one.
Background technology
Because global warming phenomenon is on the rise, advanced country there's no one who doesn't or isn't drops into a large sum of funds in energy-conservation science and technology and green energy resource to solve the problem of warming up, and warms up phenomenon to slowing down.Although in the recent period because the exploitation of shale oil and shale gas; energy crisis is made seemingly to have slightly slow trend; but on long terms; fossil energy has exhausted one day eventually; and the greenhouse gases excessively using fossil fuel to produce will cause global warming phenomenon to worsen further, to be therefore still human society very urgent and must the problem of input with all strength in carbon reduction.
Current most buildings curtain or vehicle glass all can stick thermal isolation film mostly, with the radiant heat outside isolated building or outside car, and then reduce the burden of building or air conditioning for automobiles, improve comfort level that is indoor or occupant.But most thermal isolation film does not all have antifog effect.Clammy once weather, the glass curtain in vehicle window or building is easily tied mist and affects the sight line of driver or indoor occupant.
In addition, for locomotive knight, when temperature is colder, its safety helmet lens or goggles easily tie mist because of breathing.In addition in daily life, when personnel are after hot water a period of time is opened in bathroom, mirror surfaces also can form fumulus because of the condensation of steam.Therefore, the knot mist phenomenon of article surface can cause the inconvenience of user really.
