Described adhesive layer 5 is mounting adhesive PSA glue, and it is made up of the acrylic ester adhesive of the good high transparency of weathering resistance; And in glue Homogeneous phase mixing UV absorption agent, can intercept the ultraviolet of 99%, the complex method of itself and protective layer is as follows:
Step one, the PSA glue-coating formed by acrylic ester adhesive by the good high transparency of weathering resistance is on PET release film, because coating after solvent evaporates can be thinning, so coating thickness will be controlled well according to the solid content of sizing agent, guarantee dry after the thickness of glue be 7 ~ 10um.
Step 2, be posted dry 2min under 80 DEG C of temperature condition after in surface on the protective layer of electrical spark process, due to PET release film smooth surface, glue can not be attached to it, when tearing glue will then be attached on protective layer.
Step 3, places maturation in a day under normal temperature.。
The anti-dazzle thermal isolation film that the present invention is composited by multilayer functional membrane, it effectively utilizes the polarization theory of light, namely when the plane of oscillation of light is parallel with polarization axle, light could be through, can effectively get rid of and the scattered beam in filtering light beam, avoid presbyopia, the phenomenon such as dazzling, dazzling, make sight line become clear submissive; The present invention not only has the plurality of advantages of automobile adhesive film, economizing consumption as increased attractive in appearance, safety anti-explosive, reduction air-conditioning, excluding ultraviolet, building private space, heat insulation sun, but also can dazzle be avoided, reduce the fatigue strength of driver, improve security, the clear distance of sight line significantly improves, and effectively shortens the reaction times of driver, reduces driving accident risk; During nighttime driving, as high beam or two car crosses, obviously can reduce the impact of car light on sight line, significantly improve travel safety.The present invention, except can be used for automobile adhesive film, also can be used for building glass pad pasting.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
