Description
Technical field
A kind of antistatic high temperature resistant diaphragm is the utility model is related to, belongs to laminar films product.
Background technology
For electronic apparatus class product during carrying or production and application, its surface is highly prone to contact staining or production
Raw polishing scratch scratches, and covering need to be carried out to its surface using diaphragm and make it from getting dirty or be damaged.In addition, in process
The process procedure by high temperature is generally required, so can be had higher requirements to the resistance to elevated temperatures of diaphragm.
But traditional high temperature resistant diaphragm does not have antistatic performance, and in practice, much needed by protection product
Handle under high temperature link, and consider for the influence of production technology and component in itself, often diaphragm is torn off
During electrostatic be pressed with strict requirements.
Therefore the high temperature resistant diaphragm of antistatic a kind of is needed preferably to protect the electronic apparatus class product of this demand.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is：There is provided a kind of antistatic resistance to height
Warm diaphragm, the problem of so that electrostatic can be produced when overcoming current high temperature resistant diaphragm to tear off.
To reach above-mentioned purpose, the utility model provides following technical scheme：A kind of antistatic high temperature resistant diaphragm, including
PET base material, pressure-sensitive adhesive layer and mould release membrance, wherein, the surface of the PET base material by sided corona treatment is coated with antistatic pressure sensitive glue
Layer, covered with mould release membrance on the pressure-sensitive adhesive layer, the thickness of the PET base material is 25~200um, and light transmittance is more than 85%, mist degree
Less than 6%.
After tested, diaphragm of the present utility model can tolerate 150 DEG C of * 1h high temperature, and will not be produced during tearing off
Raw larger electrostatic, prevent from having an impact production process or affixed object in itself because electrostatic is too big.
It is micro- containing the antistatic that particle diameter is 0.05nm~50um in the antistatic pressure sensitive glue-line on the basis of such scheme
Grain, 5~30um of coating layer thickness.
Preferably, the antistatic pressure sensitive glue-line uses acrylic system glue, PU systems glue or silica type pressure sensitive adhesive, described
Antistatic particle is polysulfonate acids, polythiophene class, silver powder or nanoscale nickel powder particle, the adding proportion of the antistatic particulate
For 0.5-the 10% of the pressure-sensitive adhesive layer quality.
On the basis of such scheme, the mould release membrance is 25~150um of thickness PET mould release membrances.
The beneficial effects of the utility model are：The utility model has under resistant to elevated temperatures preceding topic, also excellent static electricity resistance
Can, when peeling off the diaphragm, electrostatic pressure is zero, completely eliminates electrostatic phenomenon, is prevented because electrostatic is too greatly and to production process
Or affixed object has an impact in itself.

In the present embodiment, the pressure-sensitive adhesive layer 2 can be acrylic system glue, PU systems glue and silica type pressure sensitive adhesive,
5-30um of its coating layer thickness.
The present embodiment making step is as follows：
1）The thickness of selection PET base material 1 is 25~200um, and light transmittance is more than 85%, and mist degree is less than 6%, at least to one
Surface carries out sided corona treatment；
2）It is in the present embodiment, described pressure-sensitive in the PET base material 1 through coating antistatic pressure sensitive glue-line on sided corona treatment face
The antistatic particulate contained in glue-line 2 can be polysulfonate acids, polythiophene class, silver powder or nanoscale nickel powder particle, antistatic
The particle diameter of particulate is 0.05nm~50um, and the adding proportion of antistatic particulate is 0.5-the 10% of the mass of pressure-sensitive adhesive layer 2；
3）PET mould release membrances are covered on the pressure-sensitive adhesive layer.
Antistatic high temperature resistant diaphragm provided by the utility model can ensure affixed object do not get dirty in high temperature environments or
It is impaired, and itself will not produce pollution to affixed object.Ensure will not to produce during diaphragm is torn off simultaneously larger quiet
Electricity, production technology or affixed object will not be had an impact in itself.
The utility model above example is only one of preferred embodiment, any to embody the utility model claims
The implementation of described technical scheme, all in the scope of protection of the utility model.
It should be noted that above content be combine specific embodiment the utility model is made it is further in detail
Explanation, it is impossible to assert that specific embodiment of the present utility model is only limitted to this, under above-mentioned guidance of the present utility model, this area
Technical staff can carry out various improvement and deformation on the basis of above-described embodiment, and these are improved or deformation falls in this reality
