Abstract
The utility model relates to a release film used for solving the antistatic performance of the film, and has the technical proposal that the release film consists of a support body 1, an antistatic layer 2 and a release layer 3, both faces of the support body 1 are provided with the antistatic layer 2 after the improvement. Provided with the antistatic layer and the release layer, the release film can reduce the surface resistance, has excellent antistatic performance and high adhesive quality, and is beneficial for manufacturing and subsequent processing. The release film can be widely applicable to the field of electronics and electrical engineering as well as the manufacturing field of flat-panel display devices.
Description
Technical field
The utility model relates to a kind of membrane material, is a kind of mould release membrance specifically.
Background technology
Along with the quick growth that mould release membrance is used in the electron and electrician field, be the mould release membrance of support with high polymer plastic films such as PP, PET, because of advantages such as its dimensionally stable, easy cross cutting, of low pollution receive much attention and extensive use.Particularly in the processing and manufacturing of flat-panel display device, use mould release membrances such as PP, PET in a large number, and thus peeling force, tack, remaining adhesion rate and the antistatic behaviour etc. of mould release membrance are had higher requirement.
Coating is during mould release on the high polymer plastic film, unreel with wrapup procedure in, be easy to generate static, apparent, the release effect of influence coating.And the mould release membrance of producing in use owing to electrostatic adsorption, has a negative impact to following process easily.
Summary of the invention
The technical problems to be solved in the utility model is: improve mould release membrance high polymer diaphragm produce and/or use in unreel static characteristic with rolling, improve the tack of mould release membrance.
For addressing the above problem, the technical scheme that the utility model is taked is:
A kind of mould release membrance comprises support 1, antistatic layer 2 and release layer 3, it is characterized in that on the two sides of support 1 antistatic layer 2 being arranged.
A kind of preferred version has release layer 3 outside the antistatic layer 2 of support 1.
A kind of preferred version, described support are the high polymer pet layer.
Mould release membrance is mainly used in fields such as health, electron and electrician, food and extra package, is used as the release of pressure sensitive adhesive goods and self adhesive material.
The support that is fit to mould release membrance of the present invention can be paper and high polymer plastic films such as PP, PET, preferred high polymer PET.
Usually, on the support of mould release membrance, apply mould releases such as organic silicone oil, fluorocarbons, make, utilize the characteristic of silicon, fluorine element, make it to play release effect through heat drying curing or UV curing.
For improve mould release membrance high polymer diaphragm produce and/or use in unreel static characteristic with rolling, the mould release membrance that provides of the present invention scribbles antistatic layer on the two sides of its support, the key component of antistatic layer is the antistatic additive as polythiophene class, it can be as required, suitably adjust antistatic additive set of dispense ratio, obtain desired sheet resistance value; At the two sides of support coating antistatic additive, can adopt after single face coating, the drying again in another side coating, dry mode, can adopt also that the two sides applies simultaneously, dry mode.
The coating of mould release membrance can be dip-coating, roller coat, scraper coating and the plate gravure coating method of using always.
Beneficial effect
Mould release membrance provided by the invention, its sheet resistance is low, and antistatic property is good, and the tack height helps producing and following process.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that the another side of support also is provided with release layer.
The specific embodiment
The utility model is described in further detail below by specific embodiment.
Embodiment 1:
Coating polythiophene class antistatic additive on PET support two-sided, dry rolling applies mould release more thereon, and through 140 ℃ dry roads dry 30 seconds, rolling obtained mould release membrance.
Embodiment 2:
Coating polythiophene class antistatic additive on PET support two-sided, dry rolling applies mould release more thereon, through 140 ℃ dry roads dry 30 seconds, rolling applied mould release again on another side, through 140 ℃ dry road dry 30 seconds equally, rolling obtained mould release membrance.
Claims (3)
1. a mould release membrance comprises support (1), antistatic layer (2) and release layer (3), it is characterized in that, is provided with antistatic layer (2) on the two sides of support (1).
2. according to the described mould release membrance of claim 1, it is characterized in that, outside antistatic layer (2), be provided with release layer (3).
3. according to claim 1 or 2 described mould release membrances, it is characterized in that described support (1) is the high polymer pet layer.
