Abstract
The utility model discloses a high-temperature resistant polyethylene terephthalate (PET) protective film. The high-temperature resistant PET protective film comprises a PET substrate layer, a press-sensitive adhesive layer and a release layer, wherein the PET substrate layer, the press-sensitive layer and the release layer are compounded in turn from top to bottom. Compared with prior art, the high-temperature resistant PET protective film disclosed by the utility model has good high-temperature resistance, antistatic property, chemical corrosion resistance and anti-scratching performance. When being transported and used, the protective film can resist scratch; influences caused by high temperature, static electricity and chemical substances are reduced; and surfaces of protected substrates are not destroyed and polluted.
Description
Technical field
The utility model relates to a kind of protective material, and more particularly, the utility model relates to a kind of PET diaphragm.
Background technology
PET (PET) diaphragm is a kind of special protective material; It is attached to various digital products, all kinds of metallic plate; Plastic plate; On the surfaces such as glass, make it in manufacturing, transportation, secondary operations, storage and use, protect the surface, avoid commodity to receive pollution, scratch and reduce because the influence that high temperature, static and chemical substance are caused.High temperature resistant PET diaphragm is widely used in the particular surroundings such as high temperature, high humidity, severe corrosive and static existence or under the occasion that can require that has specific characteristics.Yet the resistance to elevated temperatures of existing in the market high temperature resistant PET diaphragm can not be satisfactory.
The utility model content
The purpose of the utility model is to the above technical problem that will solve, and a kind of high temperature resistant PET diaphragm is provided, and this is high temperature resistant, and the PET diaphragm has excellent heat-resisting quantity and antistatic property, can overcome the deficiency of prior art.
The purpose of the utility model realizes through following technical scheme:
A kind of high temperature resistant PET diaphragm is characterized in that comprising PET substrate layer, pressure-sensitive adhesive layer and release layer, and said PET substrate layer, pressure-sensitive adhesive layer and release layer are compound successively from bottom to up.
In the high temperature resistant PET diaphragm that the utility model provides, said pressure-sensitive adhesive layer is an acrylate pressure-sensitive adhesive.
In the high temperature resistant PET diaphragm that the utility model provides, said release layer is the PET mould release membrance.
Compared with prior art; The described high temperature resistant PET diaphragm of the utility model has outstanding high temperature resistance, antistatic property, resistance to chemical corrosion and anti-scratch performance; In transportation and use, can resist high temperature and scratch; Reduce because the influence that high temperature, static and chemical substance are caused, make the substrate surface of being protected not be damaged and pollute.
Description of drawings
Fig. 1 is the sectional view of the described high temperature resistant PET diaphragm of the utility model
The specific embodiment
As shown in Figure 1, the described high temperature resistant PET diaphragm of the utility model is made up of PET substrate layer 1, pressure-sensitive adhesive layer 2 and release layer 3.Said PET substrate layer 1, pressure-sensitive adhesive layer 2 and release layer 3 are compound successively from bottom to up.As a preferred embodiment of the utility model, said pressure-sensitive adhesive layer 2 is an acrylate pressure-sensitive adhesive.As another preferred embodiment of the utility model, said release layer 3 is the PET mould release membrance.
The preparation method of the described high temperature resistant PET diaphragm of the utility model is following: at first; Corona treatment is carried out on a surface to the former film of PET; Form PET substrate layer 1; Then pressure-sensitive adhesive layer 2 is evenly coated said PET substrate layer 1 on the surface of corona treatment, on pressure-sensitive adhesive layer 2, be covered with release layer 3 again.At last, the gained finished product is rolled into the diaphragm tape roll.
The utility model is not limited to above-mentioned embodiment; If spirit and scope that the various changes or the modification of the utility model do not broken away from the utility model; If these are changed and modification belongs within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and modification.
