Abstract
The invention discloses a kind of High-temperature-resandant andant wear-resistant release paper for optical protective film, be provided with base stock, plastic layer and parting agent layer, wherein, described plastic layer adopts polyformaldehyde film (POM film) to substitute conventional P E film, and between POM film and base stock, add adhesion coating, both the problem that conventional P E film is high temperature resistant and rub resistance is bad had been solved, solve again the problem that between POM film and base stock, cohesiveness is bad, High-temperature-resandant andant wear-resistant release paper for optical protective film of the present invention can be widely used in the release base stock of high-temperature electronic cross cutting diaphragm, resistance to maximum temperature can reach 250 DEG C, surface does not produce abrasion mark through scraping experiment.
Description
Technical field
The invention belongs to composite sheet field, relate generally to a kind of release liners for optical protection layer.
Background technology
Release liners, also known as silicone oil paper or separate paper, divides according to raw material and has Ge Laxin release liners, polyethylene film release liners (PEK) and kaolin to be coated with release liners three major types.Wherein polyethylene film release liners is because advantages such as its DIMENSIONAL STABILITY, produce in a large number, and at adhesive tape, the industries such as advertisement widely uses in China, and the diaphragm that wherein electronics cross cutting industry is used almost whole or major part uses PEK release liners.
The diaphragm that electronics cross cutting industry is used proposes very harsh requirement to release base stock, and as high temperature resistant, PEK surface abnormalities is smooth.And PEK release liners is because use film P E heat-resisting quantity poor, and the abrasion mark being difficult to reply can be left after mantle friction, thus make 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 above-mentioned defect; the invention provides a kind of High-temperature-resandant andant wear-resistant release paper for optical protective film; this High-temperature-resandant andant wear-resistant release paper for optical protective film has high temperature resistant and characteristic that is rub resistance, be applicable to electron-optical field, and structure is simple, easy to implement.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of High-temperature-resandant andant wear-resistant release paper for optical protective film; be provided with base stock, plastic layer and parting agent layer; described plastic layer is polyformaldehyde film; adhesion coating is provided with between described base stock and described polyformaldehyde film; the bonding described base stock of described adhesion coating and described polyformaldehyde film, described parting agent layer is coated on described polyformaldehyde film.High-temperature-resandant andant wear-resistant release paper for optical protective film of the present invention adopts polyformaldehyde film (POM film that is high temperature resistant and rub resistance; ability 250 DEG C of high temperature; surface does not produce abrasion mark through scraping experiment) substitute 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, solve again the problem that between POM film and base stock, cohesiveness is bad.
According to application range of products needs, described polyformaldehyde film (POM film) can establish one deck, and adhere on a surface of described base stock by described adhesion coating, and parting agent layer is coated with on described polyformaldehyde film (POM film), formed and singly mould isolated type High-temperature-resandant andant wear-resistant release paper for optical protective film; Described polyformaldehyde film (POM film) also can be established two-layer; and adhere on two relative surfaces of described base stock respectively by described adhesion coating; and parting agent layer is coated with on one deck or two-layer described polyformaldehyde film (POM film), formed and two mould isolated type or twoly mould two release High-temperature-resandant andant wear-resistant release paper for optical protective film.
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 does not generally wait (thickness is 0.1 ~ 10 μm) at 0.1 gram to 10 grams every square metre.
Preferably, the thickness of described polyformaldehyde film (POM film) is 15 ~ 50 μm.
The invention has the beneficial effects as follows: the plastic layer of High-temperature-resandant andant wear-resistant release paper for optical protective film of the present invention adopts polyformaldehyde film (POM film; ability 250 DEG C of high temperature; surface does not produce abrasion mark through scraping experiment) substitute 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, solve again the problem that between POM film and base stock, cohesiveness is bad.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention (moulding two release High-temperature-resandant andant wear-resistant release paper for optical protective film for two).
Detailed description of the invention
Embodiment: a kind of High-temperature-resandant andant wear-resistant release paper for optical protective film; be provided with base stock 1, plastic layer and parting agent layer 4; described plastic layer is polyformaldehyde film (POM film) 2; adhesion coating 3 is provided with between described base stock and described polyformaldehyde film; the bonding described base stock of described adhesion coating and described polyformaldehyde film, described parting agent layer is coated on described polyformaldehyde film.High-temperature-resandant andant wear-resistant release paper for optical protective film of the present invention adopts resistant to elevated temperatures polyformaldehyde film (POM film; ability 250 DEG C of high temperature; surface does not produce abrasion mark through scraping experiment) substitute 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, solve again the problem that between POM film and base stock, cohesiveness is bad.
According to application range of products needs, described polyformaldehyde film (POM film) can establish one deck, and adhere on a surface of described base stock by described adhesion coating, and parting agent layer is coated with on described polyformaldehyde film (POM film), formed and singly mould isolated type High-temperature-resandant andant wear-resistant release paper for optical protective film; Described polyformaldehyde film (POM film) also can be established two-layer; and adhere on two relative surfaces of described base stock respectively by described adhesion coating; and parting agent layer is coated with on one deck or two-layer described polyformaldehyde film (POM film), formed and two mould isolated type or twoly mould two release (as shown in Figure 1) High-temperature-resandant andant wear-resistant release paper for optical protective film.
