Abstract
The invention discloses a polythylene terephthalate (PET) aluminum foil composite release film which comprises a PET layer, an aluminum foil layer, an adhesive layer, a release coating PET and a protective layer, wherein the aluminum foil layer is arranged on one side of the PET layer; the adhesive layer is arranged between the PET layer and the aluminum foil layer; the release coating is arranged below the PET layer; the protective coating is arranged above the aluminum foil layer. According to the mode, the PET aluminum foil composite release film has the advantages of high reliability, compact structure, convenience in manufacture, good release effect, high shading coefficient, high heat resistance, convenience in use and the like, and the release film market has wide market prospects.
Description
Technical field
The present invention relates to mould release membrance field, particularly relate to the compound mould release membrance of a kind of PET aluminium foil.
Background technology
Mould release membrance refers to that surface has film separatory, and mould release membrance does not have viscosity after contacting under limited condition with specific material, or slight viscosity.Centrifugal film is seen everywhere in life, is widely used in the aspects such as packaging product, amenities and gum protection, the release poor effect of traditional mould release membrance, and adhesive force is large, is difficult for peeling off, heat resistance is poor etc.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the compound mould release membrance of a kind of PET aluminium foil, by increasing silicone oil coating coating, improves the release effect of mould release membrance; By aluminium foil layer is set, for glue-line provides effective, good protection, avoid the infringements such as ultraviolet ray, utilize the plasticity that aluminium foil is good, facilitate mould release membrance to peel off; Have the advantages such as unfailing performance is high, compact conformation, easily manufactured, release effective, and shading rate is strong, heat resistance is good, easy to use, there are market prospects widely in mould release membrance market simultaneously.
For solving the problems of the technologies described above; the technical scheme that the present invention adopts is: provide a kind of PET aluminium foil compound mould release membrance; comprise: pet layer, aluminium foil layer, adhesive phase, release coating and protective layer; described pet layer one side is provided with aluminium foil layer; in the middle of pet layer and aluminium foil layer, be provided with adhesive phase; described release coating is arranged on pet layer below, and aluminium foil layer top is provided with protective layer.
In a preferred embodiment of the present invention, described adhesive phase uses synthetic resin.
In a preferred embodiment of the present invention, described protective layer material is polyester film, and described polyester film thickness is 0.05mm.
In a preferred embodiment of the present invention, described aluminium foil layer thickness is 0.1-0.35mm, and described pet layer thickness is 0.1-0.2mm.
In a preferred embodiment of the present invention, described release coating is silicone oil coating, and described release layer thickness is 0.05mm.
The invention has the beneficial effects as follows: the compound mould release membrance of PET aluminium foil of the present invention, by increasing silicone oil coating coating, improves the release effect of mould release membrance; By aluminium foil layer is set, for glue-line provides effective, good protection, avoid the infringements such as ultraviolet ray, utilize the plasticity that aluminium foil is good, facilitate mould release membrance to peel off; Have the advantages such as unfailing performance is high, compact conformation, easily manufactured, release effective, and shading rate is strong, heat resistance is good, easy to use, there are market prospects widely in mould release membrance market simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of compound mould release membrance one preferred embodiment of PET aluminium foil of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1: pet layer, 2, aluminium foil layer, 3, adhesive phase, 4, release coating, 5, protective layer.
The specific embodiment
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
The compound mould release membrance of a kind of PET aluminium foil; comprise: pet layer 1, aluminium foil layer 2, adhesive phase 3, release coating 4 and protective layer 5; described pet layer 1 one sides are provided with aluminium foil layer 2; in the middle of pet layer 1 and aluminium foil layer 2, be provided with adhesive phase 3; described release coating 4 is arranged on pet layer 1 below, and aluminium foil layer 2 tops are provided with protective layer 5.
In the present embodiment, be arranged with the pet layer 1 after 0.1mm at the thick aluminium foil layer 2 of 0.2mm, between aluminium foil layer 2 and pet layer 1, use synthetic resin adhesive 3, guarantee good bonding effect, and guarantee good film-strength.
At the polyester film protective layer 5 being provided with above aluminium foil layer 2 after one deck 0.05mm, comparatively good protection is provided, prevent that aluminium foil from damaging.
Described release coating 4 is silicone oil coating, and described release layer 4 thickness are 0.05mm, and good release ability is provided.
The beneficial effect of the compound mould release membrance of PET aluminium foil of the present invention is:
One, by increasing silicone oil coating coating, improve the release effect of mould release membrance;
Two,, by aluminium foil layer is set, for glue-line provides effective, good protection, avoid the infringements such as ultraviolet ray;
Three, utilize the plasticity that aluminium foil is good, facilitate mould release membrance to peel off;
Four, compare existing product, the present invention has the advantages such as unfailing performance is high, compact conformation, easily manufactured, release effective, and shading rate is strong, heat resistance is good, easy to use, and there are market prospects widely in mould release membrance market simultaneously.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
