Abstract
The utility model discloses a kind of rear cover glass rupture pressure disc, the rear cover glass rupture pressure disc is from bottom to top successively including transparent release film layer, OCA layers, optical grade PET film layer and the antistatic PET film layer of optical grade.The utility model has and well prevents that glass rupture from overflowing scattered effect, light transmittance and all very high to the adhesion strength of curved surface.
Description
Technical field
The utility model is related to a kind of rupture pressure discs, and in particular to cover glass rupture pressure disc after a kind of.
Background technology
Rupture pressure disc (Explosion-proof membrane) is installed in pressure vessel top to prevent the gold of container explosion
Belong to film, be a kind of safety device.Also known as burst disk or rupture disk.When container inner pressure is more than certain limit, film elder generation quilt
It breaks through, thus the pressure in container can be reduced, avoid exploding.Using extremely wide in pressure vessel.
A kind of rupture pressure disc (publication number：Rupture pressure disc disclosed in 205130518U) includes membrane body and fits in film sheet respectively
The release film layer and protection film layer of body both sides, the membrane body include substrate layer and are arranged at substrate layer one side and are located at substrate layer
OCA layers between release film layer, which further includes the water resistant surge layer set with the opposite side of above-mentioned substrate layer, described
Protection film layer is fitted in the water resistant surge layer, which, which lays particular emphasis on, improves water resistant ripple power, and light transmittance and to curved surface
Adhesion strength is very poor.
A kind of novel optical rupture pressure disc (publication number:Rupture pressure disc disclosed in 103909698A) from outermost layer to innermost layer according to
It is secondary including：OCA optical clears glue-line, MYLAR layers, aluminium foil layer, scratch resistant layer and sound absorbing layer, it is MYLAR layers described, aluminium foil layer, scratch resistant
Using conducting resin adhesion between layer and sound absorbing layer, the rupture pressure disc light transmittance and also excessively poor to the adhesion strength of curved surface.
Utility model content
The utility model to solve the above-mentioned problems, so as to provide a kind of high transparency and to the adhesion strength of curved surface it is high after
Cover glass rupture pressure disc.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
Cover glass rupture pressure disc after a kind of, the rear cover glass rupture pressure disc from bottom to top include transparent release film layer, OCA successively
Layer, optical grade PET film layer and the antistatic PET film layer of optical grade.
In a preferred embodiment of the utility model, the thickness of the transparent release film layer for 0.03mm~
0.04mm。
In a preferred embodiment of the utility model, thickness OCA layers described is 0.015~0.025mm.
In a preferred embodiment of the utility model, the thickness of the optical grade PET film layer is 0.025mm.
In a preferred embodiment of the utility model, the thickness of the antistatic PET film layer of optical grade is 0.06mm.
The beneficial effects of the utility model are：
The utility model has and well prevents that glass rupture from overflowing scattered effect, light transmittance and to the adhesion strength of curved surface all very
It is high.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the utility model.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, rear cover glass rupture pressure disc provided by the utility model, is that the lining type of back-cover ink glass is explosion-proof
It is antistatic from bottom to top to include transparent release film layer 100, OCA layers 200, optical grade PET film layer 300 and optical grade successively for film
PET film layer 400.
Transparent release film layer 100, thickness are 0.03mm~0.04mm, are the base of the application, can directly be bonded
Onto the protected object of needs.
OCA layers 200, thickness are 0.015~0.025mm, are ultra-thin shape, are bonded in the upper of transparent release film layer 100
Surface, with stickiness.
In addition, OCA layers 200 also have excellent optical and weather resistance so that application, which has, well prevents glass from rupturing
Excessive scattered effect.
Optical grade PET film layer 300, thickness 0.025mm are for providing the explosion-proof performance of the application.
The antistatic PET film layer 400 of optical grade, thickness 0.06mm can coordinate with optical grade PET film layer 300 and cause
The explosion-proof performance of the application, light transmittance and all very high to the adhesion strength of curved surface, so that the application can be suitble to curved surface simultaneously
Glass and flat glass.
In addition, the antistatic PET film layer 400 of optical grade is also so that the application has antistatic effect.
Due in the application transparent release film layer 100, OCA layers 200, optical grade PET film layer 300 and optical grade it is antistatic
Light transmittance of PET film layer 400 itself is with regard to very high, so that the application is in the case where possessing explosion-proof effect, and light transmittance is also very
Height can reach more than 90%.
In addition, the application is by resisting transparent release film layer 100, OCA layers 200, optical grade PET film layer 300 and optical grade
The thickness of electrostatic PET film layer 400 has carried out accurate restriction so that although the application hierarchical structure is more, does not seem thick, is
Thin shape improves aesthetics.
In order to further improve the explosion-proof performance of the application, one is equipped between optical grade PET film layer 300 and OCA layers 200
Layer transparent silicon glue-line 500, so after having pressure to penetrate optical grade PET film layer 300, transparent silicon glue-line 500 can carry out pressure
Buffering reduces dynamics.
The thickness of transparent silicon glue-line 500 is 0.005mm~0.01mm, since the thickness of transparent silicon glue-line is relatively low, and is
Bright shape does not influence the light transmittance and aesthetics of the application so.
By the rear cover glass rupture pressure disc that said structure is formed, in application, explosion-proof performance is good, and having well prevents glass from breaking
Scattered effect of overflowing is split, is ultra-thin shape, aesthetics height, light transmittance reaches more than 90%, also very high to the adhesion strength of curved surface.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Simply illustrate the principle of the utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
Various changes and modifications are had, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed scope is defined by the appending claims and its equivalent thereof.
