Abstract
The utility model discloses a touch screen optic transparent glue film which comprises an upper first release liner layer, a middle adhesive gluing layer and a lower second release liner layer. The first release liner layer is a light release force polyethylene glycol terephthalate (PET) release liner layer. The adhesive gluing layer is an optic acryl adhesive gluing layer. The second release liner layer is a heavy release force PET release liner layer. The light release force PET release liner is connected with the heavy release force PET release liner in a hot attached mode through acrylic adhesives. The light release force PET release liner and the heavy release force PET release liner have high weather-proof, waterproof, high pressure resistant and ultraviolet resistant functions. By utilization of high transmittance of light of the acrylic adhesives together with the hot attachment technology, the defects that treating agents need adding and fixity is not good in a manufacture process are overcome, and therefore production cost is lowered, processing is convenient and simple, and the fixity of products is greatly improved.
Description
Technical field
The utility model relates to a kind of optical cement material membrane, is specifically related to a kind of for LCD computer, liquid crystal handset touch panel optical clear glued membrane.
Background technology
The glue paste that existing structure use to be used for cementing transparent optical element (such as camera lens etc.) is mainly: the tackiness agent such as machine silicon rubber, acrylic type resin and unsaturated polyester, urethane, Resins, epoxy, usually all need to add treatment agent, to improve its optical property clarity, high light transmittance, cost is high, heavy industry is low, can't meet the characteristic demand of new markets.
The utility model content
The purpose of this utility model is to provide a kind of high light transmittance, high tackyness, low, the easy to process simple touch-screen optical clear glued membrane of cost.
The technical solution of the utility model is, a kind of touch-screen optical clear glued membrane, comprise first release film layer on upper strata, the glue adhesion agent layer in middle layer and the second release film layer of lower floor, described the first release film layer is light off-type force PET release film layer, described glue adhesion agent layer is optics acryl glue adhesion agent layer, be connected by acrylic glue solid thermal-adhering between described the second release film layer off-type force PET release film layer of attaching most importance to, described light off-type force PET release film and heavy off-type force PET release film.
In preferred embodiment of the utility model, the thickness of described light off-type force PET release film layer is 50-100 μ m.
In preferred embodiment of the utility model, the thickness of described optics acryl glue adhesion agent layer is 25-175 μ m.
In preferred embodiment of the utility model, the thickness of described heavy off-type force PET release film layer is 50-100 μ m.
Described in the utility model is a kind of touch-screen optical clear glued membrane, light off-type force PET release film, heavy off-type force PET release film have played high weather-proof, water tolerance, high temperature resistant, anti-ultraviolet function, utilize acrylic glue solid high-transmittance collocation thermal-adhering technology to solve and add treatment agent and not good defective and the deficiency of stationarity in the processing procedure, and then reduce production costs, and this is easy to process simple, has greatly improved again the stationarity of product.
Description of drawings
Fig. 1 is the structural representation in one preferred embodiment of the utility model touch-screen optical clear glued membrane;
Each mark is as follows in the accompanying drawing: 1, light off-type force PET release film layer, 2, optics acryl glue adhesion agent layer, 3, heavy off-type force PET release film layer.
Embodiment
The below is described in detail preferred embodiment of the present utility model, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Described in the utility model is a kind of touch-screen optical clear glued membrane, referring to shown in Figure 1, comprise first release film layer on upper strata, the glue adhesion agent layer in middle layer and the second release film layer of lower floor, described the first release film layer is light off-type force PET release film layer 1, described glue adhesion agent layer is optics acryl glue adhesion agent layer 2, be connected by acrylic glue solid thermal-adhering between described the second release film layer off-type force PET release film layer 3 of attaching most importance to, described light off-type force PET release film and heavy off-type force PET release film.The thickness of described light off-type force PET release film layer 1 is 50-100 μ m.The thickness of described optics acryl glue adhesion agent layer 2 is 25-175 μ m.The thickness of described heavy off-type force PET release film layer 3 is 50-100 μ m.
Light off-type force PET release film, heavy off-type force PET release film itself have the performances such as high weather-proof, water tolerance, high temperature resistant, uvioresistant, by controllable thickness, uniform spacing is provided, and long-time use can not produce yellow (xanthochromia), peel off and rotten problem.
This touch-screen optical clear glued membrane in process of production, first with on optics acryl glue adhesion agent layer 2 liquid spreadings and the light off-type force PET release film layer 1, toast after the dry cyclisation slaking with heavy off-type force PET release film layer 3 through coater oven and to carry out rolling operation behind the thermal-adhering; Afterwards the work in-process behind the thermal-adhering can be obtained touch-screen optical clear glued membrane through post curing.
Described in the utility model is a kind of touch-screen optical clear glued membrane, light off-type force PET release film, heavy off-type force PET release film have played high weather-proof, water tolerance, high temperature resistant, anti-ultraviolet function, utilize acrylic glue solid high-transmittance collocation thermal-adhering technology to solve and add treatment agent and not good defective and the deficiency of stationarity in the processing procedure, and then reduce production costs, and this is easy to process simple, has greatly improved again the stationarity of product.
The above only is embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
