Abstract
The utility model belongs to the technical field of the releasing material technique and specifically relates to indicate a static silica gel protection film is prevented to PET bilayer, include from type membrane, silica gel layer and PET substrate layer, still include under coat and antistatic coating, static silica gel protection film is prevented to PET bilayer from the top down is in proper order for leaving type membrane, silica gel layer, under coat, PET substrate layer and antistatic coating. The utility model discloses can satisfy and waste discharge and the demand of cross cutting, realize the automation and wasted discharge soon, the face of glue levels, and is sustainable high temperature resistant, does not come unstuck not the cull and the effect of preventing static, and that has solved effectively that present single face prevents that the electrostatic protection membrane can't solve carries when rubbing or glue film production static when peeling off to make the problem that the electronic product is impaired or get dirty. Simultaneously, this PET is two -sided to prevent static silica gel protection film surface no static electricity material transport phenomena, has the prevent static electricity damage and prevents dust and impurity adsorption effect, and anti - static effect stabilizes lastingly.
Description
Technical field
The utility model relates to separated type material technical field, refers in particular to the silica gel protected film of a kind of PET double-layer antistatic.
Background technology
At present, for portions of electronics product, in the process of carrying and use, the glass substrate surface of electronic product scratches than polishing scratch such as being easier to be subject to the contact stain(ing) of some chemical substances or nail; For protecting the glass substrate surface of above-mentioned electronic product, usually needing to attach protective membrane on its surface and make it from damage and pollute.
Existing protective membrane is generally made up of substrate layer and the adhesive-layer that is coated in substrate layer surface; wherein; substrate layer generally adopts common polyester film to be prepared from; common polyester film is a kind of high molecular polymer; the advantage that specific inductivity is little, insulativity is strong though it possesses, resistivity is little, but easily produce electrostatic.When said protection film being covered on corresponding electronic product glass substrate surface, protective membrane is easy to the trickle thing such as attract dust and impurity, even can produce electrostatic and cause heavy losses, once electrostatic is excessive also can produce certain harm to user.
In addition, traditional antistatic protection film generally only has glue-line or rete anti-electrostatic, can only accomplish the effect of an anti-electrostatic.And in practice, when being peeled off by pressure-sensitive adhesive layer, or very easily produce electrostatic when there is friction in electronic product moving process, thus cause electronic product impaired or get dirty.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of can the silica gel protected film of PET double-layer antistatic of waste discharge and cross cutting; this PET double-layer antistatic silica gel protected film automatic waste discharge is fast; glue face is smooth, sustainable high temperature resistant, the effect of not cull and anti-electrostatic and efficient solution is never come unstuck.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The silica gel protected film of a kind of PET double-layer antistatic, comprises release film, layer of silica gel and PET base material layer; Also comprise undercoat and anti-static coating, the silica gel protected film of PET double-layer antistatic is followed successively by release film, layer of silica gel, undercoat, PET base material layer and anti-static coating from top to bottom.
Further, described undercoat is silicone pressure sensitive glue-line.
Further, the thickness of described release film is 70 μm ~ 90 μm, and the thickness of described layer of silica gel is 10 μm ~ 20 μm.
Further, the thickness of described anti-static coating is 20 μm ~ 30 μm, and the thickness of described PET base material layer is 30 μm ~ 50 μm; .
Preferably, the thickness of described release film, layer of silica gel, undercoat, PET base material layer and anti-static coating is respectively 73 μm, 16 μm, 20 μm, 39 μm and 26 μm.
The beneficial effects of the utility model are:
The utility model provides the silica gel protected film of a kind of PET double-layer antistatic; the main screen protection being used as electronic equipment; the utility model can meet the demand of waste discharge and cross cutting; achieve automatic waste discharge fast; glue face is smooth, sustainable high temperature resistant, the effect of do not come unstuck not cull and anti-electrostatic; produce electrostatic when efficiently solving that current one side antistatic protection film is insurmountable carries friction or when glue-line peels off, thus make the problem that electronic product is impaired or get dirty.Meanwhile, the two-sided antistatic silica gel protective membrane surface of this PET, without electrostatic material transport phenomena, has and prevents electrostatic damage and prevent dust and impurity absorption effect, anti-static effect lasting stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the silica gel protected film of the utility model PET double-layer antistatic.
Embodiment
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
As shown in Figure 1, the silica gel protected film of a kind of PET double-layer antistatic, comprises release film 1, layer of silica gel 2 and PET base material layer 4; Also comprise undercoat 3 and the silica gel protected film of anti-static coating 5, PET double-layer antistatic is followed successively by release film 1, layer of silica gel 2, undercoat 3, PET base material layer 4 and anti-static coating 5 from top to bottom.The utility model can meet the demand of waste discharge and cross cutting; achieve automatic waste discharge fast; glue face is smooth; sustainable high temperature resistant; not come unstuck the effect of not cull and anti-electrostatic; produce electrostatic when efficiently solving that current one side antistatic protection film is insurmountable carries friction or when glue-line peels off, thus make the problem that electronic product is impaired or get dirty.Meanwhile, the two-sided antistatic silica gel protective membrane surface of this PET, without electrostatic material transport phenomena, has and prevents electrostatic damage and prevent dust and impurity absorption effect, anti-static effect lasting stability.
Preferably, described undercoat 3 is silicone pressure sensitive glue-line, the thickness of described release film 1 is 70 μm ~ 90 μm, the thickness of described layer of silica gel 2 is 10 μm ~ 20 μm, and the thickness of described anti-static coating 5 is 20 μm ~ 30 μm, and the thickness of described PET base material layer 4 is 30 μm ~ 50 μm, fast to realize its automatic waste discharge, glue face is smooth, sustainable high temperature resistant, the effect of do not come unstuck not cull and anti-electrostatic.
