Abstract
The utility model discloses high-temperature and friction resistant release paper for an optical protective film. The release paper is provided with base paper, a plastic layer and a release agent layer, wherein a polyoxymethylene (POM) film substituting a conventional polyethylene (PE) coated film is adopted in the plastic layer, and an adhesive layer is arranged between the POM film and the base paper. The problem of poor high-temperature and friction resistance of the conventional PE coated film is solved, and the problem of poor adhesiveness between the POM film and the base paper is also solved; and the high-temperature and friction resistant release paper for the optical protective film can be widely applied to release base paper of a protective film for high-temperature electronic die cutting, the resistant highest temperature can reach 250 DEG C, and scratch experiments show that friction marks are not produced on the surface of the release paper.
Description
Technical field
The utility model belongs to the composite sheet field, relates generally to a kind of release liners that is used for optical protection layer.
Background technology
Release liners is claimed silicone oil paper or separate paper again, comes branch to have Ge Laxin release liners, polyethylene to drench film release liners (PEK) and kaolin coating release liners three major types according to raw material.Wherein polyethylene drenches the film release liners because advantages such as its DIMENSIONAL STABILITY are produced in China in a large number, and at adhesive tape, industries such as advertisement are widely used, wherein used almost whole the or most of PEK release liners of using of diaphragm of electronics cross cutting industry.
The diaphragm that electronics cross cutting industry is used has proposed very harsh requirement to release base stock, and as high temperature resistant, the PEK surface abnormalities is smooth etc.Heat-resisting quantity is poor and the PEK release liners is because film PE is drenched in use, and after mantle friction, can stay the abrasion mark that is difficult to reply, thereby makes diaphragm can not be applied to territories such as electronic light classes and grades in school.
The utility model content
In order to overcome above-mentioned defective; The utility model provides a kind of optical protection layer with high temperature resistant rub resistance release liners; This optical protection layer has high temperature resistant and characteristic rub resistance with high temperature resistant rub resistance release liners, is applicable to the electron-optical field, and simple in structure, easy to implement.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of optical protection layer is with high temperature resistant rub resistance release liners; Be provided with base stock, plastic layer and parting agent layer; Said plastic layer is the polyformaldehyde film; Be provided with adhesion coating between said base stock and the said polyformaldehyde film, bonding said base stock of said adhesion coating and said polyformaldehyde film, said parting agent layer is coated on the said polyformaldehyde film.The optical protection layer of the utility model adopts polyformaldehyde film (POM film high temperature resistant and rub resistance with high temperature resistant rub resistance release liners; 250 ℃ of high temperature of ability; The surperficial experiment through scraping do not produce abrasion mark) alternative conventional P E pouring film; And between POM film and base stock, add adhesion coating, both solved conventional P E and drenched the problem that film is high temperature resistant and rub resistance is bad, solved the bad problem of cohesiveness between POM film and base stock again.
According to the application range of products needs; Said polyformaldehyde film (POM film) can be established one deck; And adhere on the surface of said base stock through said adhesion coating, and go up the coating parting agent layer at said polyformaldehyde film (POM film), form and singly mould single release optical protection layer with high temperature resistant rub resistance release liners; Said polyformaldehyde film (POM film) also can be established two-layer; And adhere on two relative surfaces of said base stock through said adhesion coating respectively; And go up the coating parting agent layer at one deck or two-layer said polyformaldehyde film (POM film), form two moulds single release or twoly mould two release optical protection layers with high temperature resistant rub resistance release liners.
Preferably, said adhesion coating is water-based (emulsion) polyolefin-coated layer.Further preferably, said adhesion coating is aqueous polyethylene (PE) coating layer or aqueous polyacrylamide (PP) coating layer.Because the controllability of coating weight, the weight of said adhesion coating generally restrain 10 grams 0.1 and do not wait (thickness is 0.1～10 μ m) for every square metre.
Preferably, the thickness of said polyformaldehyde film (POM film) is 15～50 μ m.
The beneficial effect of the utility model is: the optical protection layer of the utility model adopts polyformaldehyde film (POM film with the plastic layer of high temperature resistant rub resistance release liners; 250 ℃ of high temperature of ability; The surperficial experiment through scraping do not produce abrasion mark) alternative conventional P E pouring film; And between POM film and base stock, add adhesion coating, both solved conventional P E and drenched the problem that film is high temperature resistant and rub resistance is bad, solved the bad problem of cohesiveness between POM film and base stock again.
Description of drawings
Fig. 1 is the utility model structural representation (using high temperature resistant rub resistance release liners to be example with two pair release optical protection layers of moulding).
The specific embodiment
Embodiment: a kind of optical protection layer is with high temperature resistant rub resistance release liners; Be provided with base stock 1, plastic layer and parting agent layer 4; Said plastic layer is a polyformaldehyde film (POM film) 2; Be provided with adhesion coating 3 between said base stock and the said polyformaldehyde film, bonding said base stock of said adhesion coating and said polyformaldehyde film, said parting agent layer is coated on the said polyformaldehyde film.The optical protection layer of the utility model adopts resistant to elevated temperatures polyformaldehyde film (POM film with high temperature resistant rub resistance release liners; 250 ℃ of high temperature of ability; The surperficial experiment through scraping do not produce abrasion mark) alternative conventional P E pouring film; And between POM film and base stock, add adhesion coating, both solved conventional P E and drenched the problem that film is high temperature resistant and rub resistance is bad, solved the bad problem of cohesiveness between POM film and base stock again.
According to the application range of products needs; Said polyformaldehyde film (POM film) can be established one deck; And adhere on the surface of said base stock through said adhesion coating, and go up the coating parting agent layer at said polyformaldehyde film (POM film), form and singly mould single release optical protection layer with high temperature resistant rub resistance release liners; Said polyformaldehyde film (POM film) also can be established two-layer; And adhere on two relative surfaces of said base stock through said adhesion coating respectively; And go up the coating parting agent layer at one deck or two-layer said polyformaldehyde film (POM film), form two moulds single release or twoly mould two release (as shown in Figure 1) optical protection layers with high temperature resistant rub resistance release liners.
