Abstract
The invention relates to a printable anti-scraping release agent which comprises the following components in parts by weight: 20-50 parts of polyurethane modified acrylic resin and/or polyester resin, 50-80 parts of an organic solvent and 3-5 parts of anti-scraping auxiliaries. Polyurethane modified acrylic resin and polyester resin have favorable surface tension, and have a favorable release effect with PET (polyethylene terephthalate); after stripping, a release layer is exposed outside, thus achieving a good printing effect; appropriate amount of anti-scraping auxiliaries is added, so that perfect printing effect and good coating performance are realized; meanwhile, PET deformation caused by high-temperature requirement of melamine cross-linking reaction is also avoided; and the coating temperature of the printable anti-scraping release agent is very low, thus PET deformation cannot be generated.
Description
Technical field
The invention belongs to the parting agent production technical field, relate to and print anti-scratch parting agent and application thereof on a kind of PET of being coated in film.
Background technology
Radium-shine transfer has application more and more widely in printing packaging and false proof field thereof, the holographic laser that particularly has optical anti-counterfeiting information, not only can play false proof effect, more can give strong visual effect, these functions have brought more flexible and various selection for the planners of printing packaging, be that combination is thought in holographic laser and printing, often surface energy is very low but common holography is shifted, can not print, often need to add and be coated with one deck gloss oil, could continue other pattern of printing, so not only significantly improved printing cost, and not wear-resisting, causing in press can be impaired; Transfer aspect some building materials or surface decoration need be wear-resisting, anti-scratch in addition, and for example: the transfer laser on the top ceiling needs anti-scratch, wear-resisting, and needs printing, and common parting agent does not reach needed function fully.
Before the deadline, the patent of invention of the disclosed relevant parting agent of Patent Office of the People's Republic of China has 20, includes wherein that leather changes the parting agent that film uses, the parting agent that is used for electrochemical aluminum paint, parting agent, melamine mold release agent for laser bronzing, the extraordinary parting agent that is used for electrochemical aluminum paint, label paper that environment protection type capacitor is used apply parting agent, cloudy surface parting agent and thermosetting transfer printing parting agent etc.
The patent application that approaches with the present invention has the melamine mold release agent for laser bronzing of CN200910192558.3: its composition and weight proportion are: melamine resin 33～45%, tosic acid 0.1～1%, butanone 8～10%, vinyl acetic monomer 10～15%, toluene 20～35% and butyraldehyde-n 10～25%, this patent is to utilize the crosslinking reaction of trimeric cyanamide and PET, allow trimeric cyanamide and PET complete reaction and make melamine resin not with the chromatograph resin-bonded, when peeling off, the chromatograph resin is exposed, and what can print in fact is the chromatograph resin.But in order to be beneficial to mold pressing, the chromatograph resin often will add some silicone based auxiliary agents, causes the decline of chromatograph printing performance, and the surface tension of melamine resin itself is low, is unfavorable for the levelling of coating, occurs shrinkage cavity easily in laser gold blocking.
Present most of parting agent adopts wax or silicone oil etc., though the parting agent of this type can play release effect, because the use of silicone oil reduces surface energy significantly, though can be wear-resisting, anti-scratch, but the printing effect extreme difference, thus existing parting agent be difficult to make printing, wear-resisting, anti-scratch uniting.And the present invention is very cleverly with good printing and wear-resisting, and anti-scratch this a pair of paradox is united, and is the original place of this invention; Of the present invention is a kind of printable anti-scratch release, can solve above-mentioned problem, and the more wide application space that provides of radium-shine transfer is provided.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art
,The invention provides a kind of can print, have the again anti-scratch parting agent of printing of better coating performance and application thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind ofly print anti-scratch parting agent, its component and weight proportion thereof are: 20～50 parts in polyurethane modified acrylic resin and/or vibrin, organic solvent: 50～80 parts and anti-scratch auxiliary agent: 3～5 parts.
Described organic solvent adopts ketone, ester class and/or toluene.
Described anti-scratch auxiliary agent adopts a kind of or composition between them in PE, PP, OP, PTFE wax and the Microcrystalline Wax.
Using of the present inventionly when printing anti-scratch parting agent, can print anti-scratch parting agent earlier and be coated on the above PET film of 12 μ, going up chromatograph again, or press laser information simultaneously, aluminizing, coating hot-melt adhesive is transferred on some base material then.
Described solid content 18～20% in the anti-scratch parting agent coating, anilox roll 150～220 orders, the coating dry measure 1.1～1.3g/m of printing
2Coating apparatus adopts common printed machine or coating machine, simultaneously according to status of equipment flexible solvent burden ratio.
Positively effect of the present invention is: better surface tension itself that utilize polyurethane modified acrylic resin and vibrin to have, and with PET release effect is preferably arranged, after peeling off, release layer is exposed, and good printing effect is arranged, add an amount of anti-scratch auxiliary agent, can perfectly solve and can print, coating performance is preferably arranged again, also having avoided the trimeric cyanamide crosslinking reaction needs high temperature and causes the PET distortion, coating temperature of the present invention is much lower, the problem of PET distortion can not occur.
Embodiment
The present invention is further described below in conjunction with embodiment.
A kind ofly print anti-scratch parting agent, its component and weight proportion thereof are: 20～50 parts in polyurethane modified acrylic resin and/or vibrin, organic solvent: 50～80 parts and anti-scratch auxiliary agent: 3～5 parts; Described organic solvent adopts ketone, ester class and/or toluene; Described anti-scratch auxiliary agent adopts a kind of or composition between them in PE, PP, OP, PTFE wax and the Microcrystalline Wax.
