Abstract
The invention discloses a high-temperature-resistant and wear-resistant release paper for an optical protective film, which is provided with a body paper, a plastic layer and a release agent layer, wherein the plastic layer is made of a polyformaldehyde (POM) film instead of the traditional PE (Poly Ethylene) film, and a bonding layer is additionally arranged between the POM film and the body paper, so that the problems of poor high temperature and wear resistance of the traditional PE film and poor bonding property between the POM film and the body paper are solved. The high-temperature-resistant and wear-resistant release paper for the optical protective film, provided by the invention, can be widely applied as a release body paper of a high-temperature electronic die cutting protective film and is resistant to the highest temperature up to 250 DEG C; and proved by scratch experiments, the surface of the high-temperature-resistant and wear-resistant release paper generates no abrasion marks.
Description
Technical field
The invention belongs to the composite sheet field, relate generally to a kind of release liners for optical protection layer.
Background technology
Release liners claims again silicone oil paper or separate paper, and dividing according to raw material has Ge Laxin release liners, polyethylene film release liners (PEK) and kaolin to be coated with the release liners three major types.Wherein polyethylene film release liners is because the advantage such as its DIMENSIONAL STABILITY produce in a large number in China, and at adhesive tape, the industries such as advertisement is widely used, and wherein the used diaphragm of electronics cross cutting industry almost all or most of PEK release liners of using.
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.And the PEK release liners is poor because of use film P E heat-resisting quantity, and can stay the abrasion mark that is difficult to reply after mantle friction, thereby makes diaphragm can not be applied to the territories such as electronic light classes and grades in school.
Summary of the invention
In order to overcome defects; the invention 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 present invention 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; described plastic layer is the polyformaldehyde film; be provided with adhesion coating between described base stock and the described polyformaldehyde film; the bonding described base stock of described adhesion coating and described polyformaldehyde film, described parting agent layer is coated on the described polyformaldehyde film.Optical protection layer of the present invention adopts polyformaldehyde film (the POM film of high temperature resistant and rub resistance with high temperature resistant rub resistance release liners; 250 ℃ of high temperature of ability; the surface does not produce abrasion mark through the scraping experiment) alternative conventional P E film; and between POM film and base stock, add adhesion coating; both solve the problem that conventional P E film is high temperature resistant and rub resistance is bad, solved again the bad problem of cohesiveness between POM film and base stock.
According to the application range of products needs, described polyformaldehyde film (POM film) can be established one deck, and adhere to by described adhesion coating on the surface of described base stock, and in described polyformaldehyde film (POM film) coating parting agent layer, form and singly mould single release optical protection layer with high temperature resistant rub resistance release liners; Described polyformaldehyde film (POM film) also can be established two-layer; and adhere on two relative surfaces of described base stock by described adhesion coating respectively; and in one deck or two-layer described polyformaldehyde film (POM film) coating parting agent layer, form two mould single release or twoly mould two release optical protection layers with high temperature resistant rub resistance release liners.
Preferably, described adhesion coating is water-based (emulsion) polyolefin-coated layer.Further preferably, described adhesion coating is aqueous polyethylene (PE) coating layer or aqueous polyacrylamide (PP) coating layer.Because the controllability of coating weight, the weight of described adhesion coating generally do not wait (thickness is 0.1～10 μ m) at 0.1 gram to every square metre of 10 gram.
Preferably, the thickness of described polyformaldehyde film (POM film) is 15～50 μ m.
The invention has the beneficial effects as follows: optical protection layer of the present invention adopts polyformaldehyde film (POM film with the plastic layer of high temperature resistant rub resistance release liners; 250 ℃ of high temperature of ability; the surface does not produce abrasion mark through the scraping experiment) alternative conventional P E film; and between POM film and base stock, add adhesion coating; both solve the problem that conventional P E film is high temperature resistant and rub resistance is bad, solved again the bad problem of cohesiveness between POM film and base stock.
Description of drawings
Fig. 1 be structural representation of the present invention (take two mould two release optical protection layers with high temperature resistant rub resistance release liners as example).
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; described plastic layer is polyformaldehyde film (POM film) 2; be provided with adhesion coating 3 between described base stock and the described polyformaldehyde film; the bonding described base stock of described adhesion coating and described polyformaldehyde film, described parting agent layer is coated on the described polyformaldehyde film.Optical protection layer of the present invention adopts resistant to elevated temperatures polyformaldehyde film (POM film with high temperature resistant rub resistance release liners; 250 ℃ of high temperature of ability; the surface does not produce abrasion mark through the scraping experiment) alternative conventional P E film; and between POM film and base stock, add adhesion coating; both solve the problem that conventional P E film is high temperature resistant and rub resistance is bad, solved again the bad problem of cohesiveness between POM film and base stock.
According to the application range of products needs, described polyformaldehyde film (POM film) can be established one deck, and adhere to by described adhesion coating on the surface of described base stock, and in described polyformaldehyde film (POM film) coating parting agent layer, form and singly mould single release optical protection layer with high temperature resistant rub resistance release liners; Described polyformaldehyde film (POM film) also can be established two-layer; and adhere on two relative surfaces of described base stock by described adhesion coating respectively; and in one deck or two-layer described polyformaldehyde film (POM film) coating parting agent layer, form two mould single release or twoly mould two release (as shown in Figure 1) optical protection layers with high temperature resistant rub resistance release liners.
Preferably, described adhesion coating is water-based (emulsion) polyolefin-coated layer.Further preferably, described adhesion coating is aqueous polyethylene (PE) coating layer or aqueous polyacrylamide (PP) coating layer.Because the controllability of coating weight, the weight of described adhesion coating generally do not wait (thickness is 0.1～10 μ m) at 0.1 gram to every square metre of 10 gram.
