Technical field
The present invention relates to the technical field of composite material, specially a kind of toughness and release double-layer composite material.
Background technique
Pet film is directly covered on the surface of product, in real process by the surface protecting material of existing die cutting product In, after PET film is compounded in the surface of product, since the nucleus of product has certain thickness relative to the integral face domain of product Degree, the integral planar degree of PET film is bad, it is easier that whole planarization is poor, so that PET film imitates the Global Macros of product Fruit reduces, the overall appearance of product is plain.
Summary of the invention
In view of the above-mentioned problems, making product the present invention provides a kind of toughness and release double-layer composite material PET film in the smooth fitting of nucleus with thickness, and the periphery for ensuring product guarantees the table for product with protection The planarization in face attaches.
A kind of toughness release double-layer composite material again, it is characterised in that: it includes PET protection film, release film, described PET protection film includes the first PET matrix layer, antistatic coating, layer of silica gel, and the release film includes the second PET matrix layer, silicone oil Coating, the exposed surface of the layer of silica gel are compounded with the non-silicone coating face of the second PET matrix layer.
It is further characterized by: the exposed surface of the silicone coating is used for the peripheral surface domain region of laminating product, institute The thickness concave portion that the second PET matrix layer is stated corresponding to product passes through punching waste discharge removal, the thickness male part of the product Divide and only remain with PET protection film, the layer of silica gel of the corresponding region of the PET protection film directly attaches the thickness male part of product The surface divided, it is ensured that the overall leveling of PET protection film；
The PET protection film is specially blue PET protection film, and the release film is specially matte release film, so that whole Product serves as release film and protective film dual role, and blue PET protection film has both been protected to correspond to area's product thickness concave portion The viscosity of Jiao Qu and the surface in the area Fei Jiao, and have the fool proof above color；
Thickness of the thickness of the matte release film no more than the thickness concave portion of product, it is ensured that blue PET protection film Jiao Qu the thickness concave portion of product is attached；
Preferably, the first PET matrix layer of the blue PET protection film with a thickness of 36 μm, the second of the release film PET matrix layer with a thickness of 25 μm, the integral thickness of double-layer composite material is 61 μm~72 μm；
The peeling force of the release Matte film is 5~10g/25mm；
The viscosity of the layer of silica gel of the blue PET protection film is 3-6g/in, and viscosity is low, and waste discharge is easy to arrange in punching Remove matte release film, according to shape of product removal corresponding region matte release film after layer of silica gel remaining adhesion rate >= 85%；
The antistatic parameter of the glue surface of the antistatic coating is 106-1011 Ω, and pre- antistatic is excessive to adsorb product.
After adopting the above technical scheme, being combined with each other without silicone oil face by the layer of silica gel of PET protection film and release film, multiple Closing the Matte film on protective film has good flexibility and docile property, compound easily to cause fold bubble etc. up Bad, release film effectively realizes the structure that entire material forms indent Jiao Qu by punching press waste discharge, release film composition Material is conveniently taken in adhesive-free area, the glue surface with faint viscosity of PET protection film protects the surface for protecting product, which reduce The cost of raw material；And release film punching can cut out required shape, also there is good planarization as auxiliary film；To sum up, PET film in its fitting for making the nucleus with thickness of product smooth, and the periphery for ensuring product guarantees with protection The planarization on the surface of product is attached.
Detailed description of the invention
Fig. 1 is schematic diagram of product structure of the invention；
Fig. 2 is to be formed after being punched waste discharge on release film for attaching the structural schematic diagram of product；
Title corresponding to serial number is as follows in figure:
PET protection film 1, the first PET matrix layer 11, antistatic coating 12, layer of silica gel 13, release film 2, the second PET matrix Layer 21, silicone coating 22, notch 23.
Specific embodiment
A kind of toughness and release double-layer composite material, see Fig. 1, Fig. 2: it includes PET protection film 1, release film 2, PET Protective film 1 include the first PET matrix layer 11, antistatic coating 12, layer of silica gel 13, release film 2 include the second PET matrix layer 21, Silicone coating 22, the exposed surface of layer of silica gel 13 are compounded with the non-silicone coating face of the second PET matrix layer 21.
See Fig. 2: the exposed surface of silicone coating 22 is used for the peripheral surface domain region of laminating product, the second PET matrix layer 21 By punching waste discharge removal, formation notch 23, the thickness concave portion of product only retains thickness concave portion corresponding to product There is PET protection film 1, the layer of silica gel 13 of the corresponding region of PET protection film 1 directly attaches the table of the thickness concave portion of product Face, it is ensured that the overall leveling of PET protection film 1；
PET protection film 1 is specially blue PET protection film, and release film 2 is specially matte release film, so that integral product is filled When release film and protective film dual role, blue PET protection film was both protected to correspond to the Jiao Qu's of area's product thickness concave portion The surface in viscosity and the area Fei Jiao, and have the fool proof above color；
Thickness of the thickness of matte release film no more than the thickness concave portion of product, it is ensured that the glue of blue PET protection film Area attaches the thickness concave portion of product；
In specific embodiment, the first PET matrix layer 11 of blue PET protection film with a thickness of 36 μm, the second of release film PET matrix layer 21 with a thickness of 25 μm, the integral thickness of double-layer composite material is 61 μm~72 μm；
The peeling force of release Matte film is 5~10g/25mm；
The viscosity of the layer of silica gel 13 of blue PET protection film is 3-6g/in, and viscosity is low, and waste discharge is easy to venting in punching Matte release film, according to shape of product removal corresponding region matte release film after layer of silica gel 13 remaining adhesion rate >= 85%；
The antistatic parameter of the glue surface of antistatic coating 12 is 106-1011 Ω, and pre- antistatic is excessive to adsorb product.
Its working principle is as follows, and being combined with each other without silicone oil face for the layer of silica gel of PET protection film and release film is compounded in Matte film on protective film has good flexibility and docile property, compound easily to cause fold bubble etc. no up Good, release film effectively realizes the structure that entire material forms indent Jiao Qu, the nothing of release film composition by punching press waste discharge Jiao Qu conveniently takes material, the glue surface with faint viscosity of PET protection film protects the surface for protecting product, and which reduce originals Material cost；And release film punching can cut out required shape, also there is good planarization as auxiliary film；To sum up, So that PET film in the smooth fitting of the nucleus with thickness of product, and the periphery for ensuring product is with protection, guarantees pair Planarization in the surface of product attaches.
