The utility model provides a novel double-sided shading adhesive. The novel double-sided shading adhesive comprises a double-sided shading adhesive tape, a release film and single silicon release paper, wherein the double-sided shading adhesive tape comprises a shading layer and an adhesive layer; the shading layer is a PET (polyethylene terephthalate) polyester film layer; the adhesive layer is a double-sided adhesive tape; the adhesive layer is fixedly connected with the surface of the shading layer via a sticker layer on one surface of the adhesive layer; the release surface of the release film and the other surface of the shading layer are laminated; and the upper surface of the adhesive layer is covered by the single silicon release paper. The novel double-sided shading adhesive has a simple, reasonable and compact structure, overcomes various defects of the prior art, and has the advantages of high temperature and moisture resistance, excellent insulating, shading and reflecting properties, easiness in punching processing and the like compared with the prior art. Besides, the novel double-sided shading adhesive is low in cost, is easy to implement, has a good implementation effect and has strong practicability and extensive market prospects.
Description
Technical field
The utility model relates to indicating meter and backlight module field, especially relates to a kind of novel two-sided shading glue.
Background technology
Be the electronic information epoch now, electronic products such as mobile phone, computer, digital camera are universal day by day.LCD liquid-crystal display and backlight module are fixing to require to provide a kind of shading to reflect double sticky tape.The cross cutting goods of two-sided shading glue are mainly used in the bonding in fields such as notebook computer, mobile phone, server LCD periphery, and its effect is that bonding plays a shield lights afterwards.Existing shading reflection double sticky tape exist many shortcomings as: can not be than using under the elevated operating temperature, be afraid of that humidity, fertile insulation system, opacifying property and reflective are poor, being not easy to stamp processing etc.
Under different situations, thickness to shading rubber belt has different requirements, in order to regulate the thickness of shading rubber belt, usually utilize the thickness of regulating glue layer to regulate the thickness of shading rubber belt, but when glue layer surpasses certain thickness (generally greater than 0.015mm), in shading rubber belt machine-shaping process, when two-sided shading glue carries out cross cutting, also have impression on the double faced adhesive tape product, crumple, glue overflows, distortion and size bad phenomenon, when pasting clothes, easily pasting the very difficult bubble of discharging of clothes face generation, cause product bad, thereby influence the quality of module light-emitting area backlight.
Summary of the invention
The utility model purpose provides a kind of novel two-sided shading glue.During with solution existing in prior technology cross cutting, technical problems such as having impression on the two-sided shading glue and crumple, glue, distortion and the size of overflowing is bad.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel two-sided shading glue, comprise two-sided shading rubber belt, release film, single silicon separate-type paper, described two-sided shading rubber belt comprises light shield layer and adhesive layer, wherein light shield layer is the PET laminated polyester film, and adhesive layer is double sticky tape; Described adhesive layer is fixedly connected on the surface of described light shield layer by the adhering agent layer of one surface; Release and another surface recombination of light shield layer of described release film, the adhesive layer upper surface is coated with single silicon separate-type paper.
As preferably, described light shield layer is provided with two-layer, and this light shield layer is black PET laminated polyester film.
As preferably, described two-sided shading rubber moulding is cut, straight outer oblique cutter in adopting, and wherein this cutter obliquity is 25 °, knife up 1.5mm.
The utlity model has simple and reasonable for structurely, compact, overcome many shortcomings of prior art, compared with prior art have high temperature resistant, humidity, insulation, opacifying property and reflective good, be easy to advantages such as stamp processing.On release film, change the base stock recoil of former factory and cut by two-sided shading rubber belt is multiple, when cross cutting, can effectively reduce crumple and double faced adhesive tape on impression.When artificial subsides are obeyed, can not paste the bubble that the generation of clothes face is difficult to discharge, it has significantly promoted the stickup performance of two-sided shading glue, no light leakage phenomena.And, with low cost, easy to implement, and implementation result is good.Have very strong practicality, market outlook are wide.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 a-2b is cross cutting schema of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Fig. 1 is structural representation of the present utility model.As shown in Figure 1, a kind of novel two-sided shading glue, mainly formed by two-sided shading rubber belt, release film 4, single silicon separate-type paper 1 etc., wherein two-sided shading rubber belt comprises light shield layer 3 and adhesive layer 2, this light shield layer 3 is the PET laminated polyester film, light shield layer 3 is provided with two-layer, and this light shield layer 3 is black PET laminated polyester film, and adhesive layer 2 is double sticky tape; Described adhesive layer 2 is fixedly connected on the surface of described light shield layer 3 by the adhering agent layer of one surface; Release and light shield layer 3 another surface recombination of described release film 4, adhesive layer 2 upper surfaces are coated with single silicon separate-type paper 1.
Fig. 2 a-2b is cross cutting schema of the present utility model.By Fig. 2 a-2b further as can be known, when two-sided shading glue carries out cross cutting, adopt engraving five metals mould, the interior straight outer oblique knife edge, wherein this cutter obliquity is 25 °, knife up 1.5mm; Hemisection from the surface of single silicon separate-type paper 1 during cross cutting, thus make this two-sided shading glue product not have impression, distortion, the glue that overflows, problem such as size is bad.Earlier to the freezing processing of two-sided shading rubber belt, and be compounded in release of release film 4 before the cross cutting processing, tear up two-sided shading rubber belt and carry facial tissue, change single silicon separate-type paper 1, punching press is (shown in Fig. 2 a) for the first time, and waste discharge is handled automatically; Compound single silicon separate-type paper 1 more afterwards, punching press (shown in Fig. 2 b) for the second time from the negative, problem such as whole-course automation solves the glue that overflows, and size is bad.On release film 4, change the base stock recoil of former factory and cut by two-sided shading rubber belt is multiple, when cross cutting, can effectively reduce crumple and double faced adhesive tape on impression.When artificial subsides are obeyed, can not paste the bubble that the generation of clothes face is difficult to discharge, it has significantly promoted the stickup performance of two-sided shading glue, no light leakage phenomena.And, with low cost, easy to implement, and implementation result is good.
