Such as keep the high grade of transparency, there is splendid added property and illustrative, and keep the highest strong
Degree, does not affect transport, stores and use, as public in China Application No. CN 203267424 U
Having opened a kind of antifog film, including pet base material, described pet base material is arranged over anti-fog layer, should
Anti-fog layer is arranged over diaphragm, and adhesive-layer is passed through with release in the lower section of the most described pet base material
Paper is bonding, the antifog film Main Auto vehicle window of this technology, rearview mirror, high-grade hotel glass with
And Domestic glass is first-class, the heat of major part solar energy can be reflected back in hot summer,
Play holding indoor temperature and will not raise too much, reduce room conditioning load, thus reach energy-conservation
Purpose, it addition, the antifog film illustrated its one side be tough and tensile PET base material, one side be viscous
Glue-line, this adhesive-layer has good bonding force, if eyeglass is not with the one side of eyeglass japanning
Carefully being staved, fragment will be glued without falling down, and is so possible to prevent to be scattered
Glass people and other article may be caused damage, but the antifog film of this technology is the most preferably
Glossiness, simultaneously the most not there is preferable acid and alkali-resistance, anticorrosive, resistance to ag(e)ing, be unsuitable for
The food such as packaging fresh water fruits and vegetables.
Summary of the invention
It is an object of the invention to provide a kind of antifog film, upper with solve prior art causes
State multinomial defect.
A kind of antifog film, including resistance to photosphere, anti-fog layer, sandwich layer and protective layer, on described sandwich layer
Side is provided with anti-fog layer, and described anti-fog layer is arranged over resistance to photosphere, is provided with protection below described sandwich layer

Preferably, described anti-fog layer is the composite of BMA and EA material, and mass ratio is 1.3-
1.7:1。
Preferably, described protective layer is HDPE material.
It is an advantage of the current invention that: antifog film has the preventing atomization performance of excellence, preferable gloss
Degree, has preferable acid and alkali-resistance, anticorrosive, resistance to ag(e)ing simultaneously, and resistance to photosphere is PBT and PC
Composite, the composite of PBT and PC has heat-resist, resistance to optical good, tool
Have excellent wear-resisting, chemical resistance, sandwich layer is PA material, and thickness is 15-20 μm,
PA material has preferable tensile property, low cost, and light transmittance is high, tear-proof, resistance to deformation
Modulus is big, and anti-fog layer is the composite of BMA and EA material, BMA and EA material
It is good that composite has anti-fog performance, Heat stability is good, and protective layer is HDPE material, HDPE
Material has the most anti-aging, uvioresistant, meanwhile, also has good chemical stability,
Resistance to height, low temperature, the chemical solution such as acid and alkali resistance, salt, it is suitable for packaging fresh water fruits and vegetables
Deng, it is nontoxic environment-friendlymembrane membrane.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of antifog film of the present invention.
Fig. 2 is the side view of a kind of antifog film of the present invention.
Wherein: the resistance to photosphere of 1-, 2-anti-fog layer, 3-sandwich layer, 4-protective layer.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be prone to bright with effect
White understanding, below in conjunction with detailed description of the invention, is expanded on further the present invention.
As depicted in figs. 1 and 2, a kind of antifog film, including resistance to photosphere 1, anti-fog layer 2, sandwich layer 3
