Abstract

The utility model discloses a release film layer structure. The release film layer structure comprises a support body, antistatic layers and release layers, wherein the support body, the antistatic layers and the release layers are arranged in sequence in a laminated manner, wherein the antistatic layers are adhered to two surfaces of the support body; the release layers are arranged outside the antistatic layers. The release film layer structure adopting the scheme has the advantages of low surface resistance, good antistatic property and high adhesiveness, and is favorable for production and follow-up processing.

Description

A kind of release film layer structure

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 extremely parent's concern and extensive uses of advantages such as its dimensionally stable, easy cross cutting, of low pollutions.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.When on cured of high polymer plastics, applying mould release, unreel with wrapup procedure in, be easy to generate static, influence applies and watches quietly, release effect.And the mould release membrance of producing in use owing to electrostatic adsorption, has a negative impact to following process easily.

The utility model content

To the problems referred to above, the utility model aim to provide a kind of improve mould release membrance high polymer diaphragm produce and/or use in unreel the static characteristic with rolling, improve the release film layer structure of the tack of mould release membrance.

For realizing this technical purpose, the scheme of the utility model is: a kind of release film layer structure, said mould release membrance comprise support, antistatic layer and the release layer of sequential cascade, are pasted with antistatic layer on the two sides of support, and this antistatic layer has release layer outward.

As preferably, said support is the high polymer pet layer.

Its sheet resistance of mould release membrance structure of this programme is low, and antistatic property is good, and tack is high, helps producing and following process.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural representation that the another side of support also is provided with release figure.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.

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.A support that is fit to this novel mould release membrance can be high polymer plastic films such as paper and 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.

Mould release membrance high polymer diaphragm unreels in production and/or use or the static characteristic of rolling in order to improve; A kind of mould release membrance of the utility model, as illustrated in fig. 1 and 2, comprise support 1, antistatic layer 2 and release layer 3; It is characterized in that; On the two sides of support 1 antistatic layer 2 is arranged, antistatic layer 2 is arranged, outside the antistatic layer 2 of support 1, release layer 3 is arranged on the two sides of support 1.

Through specific embodiment the utility model is described further below.

Embodiment 1:

On PET support two-sided, apply the polythiophene class antistatic additive, dry rolling applies mould release more on it, and through 140 ℃ dry roads dry 30 seconds, rolling obtained mould release membrance.

Embodiment 2:

On PET support two-sided, apply the polythiophene class antistatic additive, dry rolling applies mould release more on it; Dry 30 seconds of the dry roads that warp is 140 ℃, rolling applies mould release again on another side; Equally through dry 30 seconds of 140 ℃ dry road, rolling obtained mould release membrance.

The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection domain of the utility model technical scheme.

Claims

1. release film layer structure, said mould release membrance comprises support, antistatic layer and the release layer of sequential cascade, it is characterized in that: the two sides at support is pasted with antistatic layer, and this antistatic layer has release layer outward.

2. a release film layer structure is characterized in that, said support is the high polymer pet layer.
