Abstract
The utility model belongs to functional film technical field, particularly relates to a kind of rupture pressure disc, particularly a kind of antireflection rupture pressure disc, and its structure comprises protective film, antireflection hardened layer, PET base material layer, adhesive layer and release layer successively; Wherein, antireflection hardened layer be its at least one side be coated with at least one deck low refractive index dielectric add hard resin layer, adhesive layer is two-period form OCA optical cement.Protective film is antistatic PET protection film, and the thickness of antireflection hardened layer is 3 μm ~ 5 μm, and the thickness of PET base material layer is 50 μm ~ 125 μm, and the thickness of adhesive layer is 20 μm ~ 50 μm.The adhesive that the utility model adopts is two-period form OCA optical cement, low in laminating initial stage adhesion strength, and conveniently locate, easily do over again, after UV-irradiation, adhesion strength promotes, and has higher adhesion strength, can play more effective explosion-proof; The utility model adopt be coated with low refractive index dielectric add animi resin, effectively can reduce light reflection, there is excellent antireflective effect.
Description
Technical field
The invention belongs to functional film technical field, particularly relate to a kind of rupture pressure disc, particularly a kind of rupture pressure disc with anti-reflection function.
Background technology
Flourish along with electronics technology, rupture pressure disc is widely used in display unit industry, as the various optical displays on the electronic products such as smart mobile phone, digital code camera, notebook computer, panel computer, wearable smart machine.Because the optical display of electronic product is generally made with glass, when being subject to extraneous shock, very easily broken splashing, produces great potential safety hazard to human body, so the use of rupture pressure disc can protect the safety of electronic product user effectively.General as electronic products such as mobile phones, use can produce strong reflective in the sun, not only can produce visual interference to user, affect experience, but also may affect the sight line of people around.For vehicle electronics screen, sunlight can be subject in the process of moving and irradiate, easily produce reflective, affect driver's sight line, there is very large potential safety hazard.In addition, the screen protecting film adopted in the market easily produces bubble when pasting, and not easily discharges, and not only affects the aesthetics of product after pad pasting, and affects experience.
Patent document CN202924088U proposes a kind of anti-dazzle diaphragm, comprises protection transparent film layer, uses transparent film layer and peel off transparent film layer; Wherein, use the upper surface of transparent film layer to be provided with the scratch resistant layer that one deck has anti-dazzle effect, be provided with the tack coat of one deck polyurethane resin or organosilicon glue-line at its lower surface; Especially, it is consistent that scratch resistant layer surface has pore size, the uniform pore structure of surface distributed.This technical scheme can obtain that transparency is good, hardness is high, the anti-dazzle diaphragm of scratch-resistant.But owing to employing common polyurethane resin or organic silica gel as binding agent, easily produce bubble when pad pasting, shock resistance simultaneously, explosion-proof performance are not effectively improved.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of there is high rigidity, shock resistance, antireflection, more easily carry out the rupture pressure disc of pad pasting operation.
The object of the invention is to be realized by following technical proposals.
A kind of rupture pressure disc; comprise protective film, antireflection hardened layer, PET base material layer, adhesive layer and release layer successively; wherein, described antireflection hardened layer be its at least one side be coated with at least one deck low refractive index dielectric add hard resin layer, described adhesive layer is two-period form OCA optical cement.
Preferably, described protective film selects antistatic PET protection film.
Preferably, the thickness of described antireflection hardened layer is 3 μm ~ 5 μm.
Preferably, the thickness of described PET substrate layer is 50 μm ~ 125 μm.
Preferably, the thickness of described adhesive layer is 20 μm ~ 50 μm.
A kind of rupture pressure disc of the present invention has following beneficial effect: the adhesive that the present invention adopts is two-period form OCA optical cement, low in laminating initial stage adhesion strength, conveniently locate, easily do over again, after UV-irradiation, adhesion strength promotes, there is higher adhesion strength, more effective explosion-proof can be played; The present invention adopt be coated with low refractive index dielectric add animi resin, effectively can reduce light reflection, there is excellent antireflective effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of rupture pressure disc of the present invention.
In described Fig. 1,1 is protective film, and 2 is antireflection hardened layer, and 3 is PET base material layer, and 4 is adhesive layer, and 5 is release layer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1; a kind of rupture pressure disc; once comprise protective film 1, antireflection hardened layer 2, PET base material layer 3, adhesive layer 4 and release layer 5; wherein; antireflection hardened layer 2 be the one side near PET base material layer 3 and/or be coated with at least one deck low refractive index dielectric near the one side of protective film 1 add animi resin, adhesive layer 4 is two-period form OCA optical cement.Generally, the refractive index 1.2 ~ 1.7 of available low refractive index dielectric; In the present embodiment, the refractive index of the low refractive index dielectric selected is 1.24 ~ 1.29.In actual production process, hardening liquid (as light-cured resin) is coordinated levelling agent and other auxiliary agents, PET base material surface is coated by anilox roll, utilize UV to be cured and obtain adding hard resin layer, low refractive index dielectric is plated at least one face adding hard resin layer again, namely obtains antireflection hardened layer.In the present embodiment, protective film 1 selects antistatic PET protection film, and the thickness of antireflection hardened layer 2 is 3 μm ~ 5 μm, and the thickness of PET base material layer 3 is 50 μm ~ 125 μm, and the thickness of adhesive layer 4 is 20 μm ~ 50 μm.
By reference to the accompanying drawings detailed description is done to the preferred detailed description of the invention of the utility model above, but the utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art possess, can also make a variety of changes without departing from the concept of the premise utility.
