Abstract
The invention provides a protective film with a PU (polyurethane) adhesive, comprising a PET (polyethylene terephthalate) transparent film, the PU adhesive and a PET release film, wherein the PU adhesive is coated on the PET transparent film, and the PET release film is coated on the PU adhesive; the thickness of the PET transparent film is 50 or 75mum; the thickness of the PU adhesive is 8-10mum; and the thickness of the PET release film is 23 or 25mum. The protective film with the PU adhesive provided by the invention has the beneficial effects of being low in adhesion, high in temperature, high in humidity, pollution-free, good in automatic adsorptivity, excellent in air bubble removal effect, and capable of preventing glass optical lenses from fogging.
Description
[technical field]
The present invention relates to a kind of diaphragm, relate in particular to a kind of PU glue diaphragm.
[background technology]
Most diaphragm exists high adhesion on the market now, and high temperature, high humidity are seriously polluted, and automatic absorbing is poor, exhaust bubble weak effect, the deficiency that hazes easily during the glass lens protection.
[summary of the invention]
The object of the invention is to overcome in the present technology most diaphragm and exist high adhesion, high temperature, high humidity are seriously polluted, and automatic absorbing is poor, exhaust bubble weak effect, the deficiency that hazes easily during the glass lens protection and a kind of novel PU glue diaphragm that provides.
The present invention is achieved through the following technical solutions: a kind of PU glue diaphragm, comprise PET hyaline membrane, polyurethane adhesive, PET mould release membrance, and described PET hyaline membrane top is coated with polyurethane adhesive, and described polyurethane adhesive top is covered with the PET mould release membrance.
Further, the thickness of described PET hyaline membrane is: 50 or 75 μ m.
Further, the thickness of described polyurethane adhesive is: 8 to 10 μ m.
Further, the thickness of described PET mould release membrance is: 23 or 25 μ m.
Can be used for capacitance plate manufacturing process and shipment protection;
The lens protection that also can be used for mobile phone or other electronic products
Beneficial effect of the present invention is: have low adhesion, high temperature, high humidity is pollution-free, and automatic absorbing is good, exhaust bubble effect is excellent, and the glass lens protection is not hazed.
[description of drawings]
Fig. 1 is the high temperature resistant carrying adhesive tape structure of the present invention schematic diagram;
Reference numeral: 1, PET hyaline membrane; 2, polyurethane adhesive; 3, PET mould release membrance.
[specific embodiment]
Below in conjunction with the drawings and the specific embodiments the present invention is described further:
Example 1:
Be used for capacitance plate manufacturing process and shipment protection:
As shown in Figure 1, a kind of PU glue diaphragm comprises PET hyaline membrane, polyurethane adhesive, PET mould release membrance, and described PET hyaline membrane top is coated with polyurethane adhesive, and described polyurethane adhesive top is covered with the PET mould release membrance.
Further, the thickness of described PET hyaline membrane is: 50 μ m.
Further, the thickness of described polyurethane adhesive is: 8 μ m.
Further, the thickness of described PET mould release membrance is: 23 μ m.
Cover on the capacitance plate of the mobile phone that needs protection or other electronic products after PET mould release membrance of the present invention can being removed, can in the process of production, shipment, transportation, use, protect the capacitance plate of mobile phone or other electronic products.
Example 2:
The lens protection that is used for mobile phone or other electronic products
As shown in Figure 1, a kind of PU glue diaphragm comprises PET hyaline membrane, polyurethane adhesive, PET mould release membrance, and described PET hyaline membrane top is coated with polyurethane adhesive, and described polyurethane adhesive top is covered with the PET mould release membrance.
Further, the thickness of described PET hyaline membrane is: 75 μ m.
Further, the thickness of described polyurethane adhesive is: 10 μ m.
Further, the thickness of described PET mould release membrance is: 25 μ m.
Cover on the lens wearer of the mobile phone that needs protection or other electronic products after PET mould release membrance of the present invention can being removed, in the process of production, shipment and transportation, protect mobile lens.
The according to the above description announcement of book and instruction, those skilled in the art in the invention can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications and changes more of the present invention.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the present invention just for convenience of description.
