Description
Technical field
The utility model relates to a kind of membrane material for the protection of glue material, particularly relates to a kind of mould release membrance.
Background technology
Mould release membrance refers to that surface has film separatory, does not have viscosity after mould release membrance contacts under limited conditions with adhesive film material, or slight viscosity, effectively can protect adhesive film material.The release layer that mould release membrance is generally divided into middle substrate layer and sticks with adhesive film material.In the prior art, the release layer of mould release membrance is directly coated on the substrate layer of mould release membrance, but this scheme makes the adhesive force between release layer and substrate layer poor, when peeling off mould release membrance, release layer on mould release membrance can be taken away by the adhesive film material sticking adhesion larger, the mould release membrance release layer region being difficult to clean out can be produced in the local surfaces of adhesive film material, destroy pad pasting globality and uniformity; Existing mould release membrance and adhesive film material major part are all transparent in addition, and be difficult to when peeling off distinguish, overcome this problem why, mould release membrance produced by some enterprise's coloured thin-film material of choice for use band, but the production cost of this mould release membrance is high; Existing mould release membrance can not prevent the generation of electrostatic in addition, easily causes the phenomenons such as sticky ash, have impact on the normal use of mould release membrance.Therefore, a kind of antistatic, easy resolution of design is needed and release layer and substrate layer stick the stronger mould release membrance of adhesion.
Summary of the invention
In order to overcome mould release membrance in prior art not antistatic, be not easy to pad pasting and distinguish and release layer and substrate layer stick the more weak defect of adhesion, provide antistatic, the easy resolution of one and release layer and substrate layer stick the stronger mould release membrance of adhesion.
The utility model is realized by following proposal:
A kind of mould release membrance, the release layer comprising substrate layer, cohere mutually with substrate layer, the face that described substrate layer contacts with release layer is provided with the reinforcing groove matched and bulge-structure, antistatic layer is provided with in described substrate layer another side correspondence, be provided with dope layer at the another side of described antistatic layer, the surface of described substrate layer is provided with reinforcing fine hair.
The thickness of described substrate layer is 90 ~ 200 microns.
The thickness of described release layer is 30 ~ 100 microns.
The degree of depth of described reinforcing groove is 0.1 ~ 0.4 times of substrate layer thickness.
The beneficial effects of the utility model are:
1. the face that the substrate layer of a kind of mould release membrance of the present utility model contacts with release layer is provided with reinforcing groove, add the contact area of substrate layer and release layer, effectively improve release layer and substrate layer sticks adhesion, prevent when peeling off mould release membrance, the release layer on mould release membrance can be taken away by the adhesive film material sticking adhesion larger;
2. the substrate layer of a kind of mould release membrance of the present utility model is provided with reinforcing fine hair on the surface, and that can strengthen substrate layer and release layer and antistatic layer sticks adhesion, improves the structural stability of mould release membrance, makes its longer service life;
3. a kind of mould release membrance of the present utility model is provided with antistatic layer, effectively can solve the sticky grey problem that electrostatic causes;
4. a kind of mould release membrance of the present utility model is provided with dope layer, can differentiate mould release membrance and adhesive film material than being easier to.
