Abstract
The invention discloses an anti-scratching writing coating which comprises the following components in percentage by weight: 25-45% of basic resin, 15-35% of active monomer, 20-40% of solvent, 1-8% of photoinitiator, 0.05-1% of leveling agent, 0.01-1% of defoamer and 0.01-1% of coupling agent. When being applied to a PET (polyethylene terephthalate) film surface, the coating can enhance the wear resistance, scuff resistance and scratch resistance of the film surface, and prolong the service life of the film.
Description
Technical field:
The present invention relates to film protection field, relate in particular to a kind of anti-zoned coating of writing.
Background technology:
In numerous thin-film materials, polyester film (PET) has that tensile strength is large, electrical insulation capability and good in optical property, heat-resisting, resistance oxygen, resistance is wet and the good characteristics such as stability, and therefore the various product application take polyester film as base material are extensive.In the pad pasting field of writing take the PET film as base material, at film surface, often to write and wiping, yet, due to defects such as the surface hardness of PET material are low, wear no resistance, make the application of polyester film be subject to certain restrictions or cause the finished product to have certain defect.Solve the defects such as polyester film wears no resistance, the performances such as scuff resistance that can be by the film surface applying coating being improved to the film surface, wear resistance, except the function of improving thin-film material, can also improve the work-ing life of thin-film material.
Summary of the invention:
The purpose of this invention is to provide a kind of anti-zoned coating of writing, it has good sticking power, and wear resistance is good, it is coated in to the PET film surface and can extends its work-ing life.
Purpose of the present invention is achieved through the following technical solutions:
A kind of anti-zoned coating of writing comprises following component by weight percentage: base resin 25-45%, reactive monomer 15-35%, solvent 20-40%, light trigger 1-8%, flow agent 0.05-1%, defoamer 0.01-1%, coupling agent 0.01-1%.
Preferred as technique scheme, described base resin is urethane acrylate.
Preferred as technique scheme, described reactive monomer are a kind of in epoxy acrylate, Viscoat 295, neopentylglycol diacrylate, hexanediyl ester, tetramethylol methane tetraacrylate.
Preferred as technique scheme, described solvent is one or more mixtures in toluene, ethyl acetate, butylacetate, dimethylbenzene.
Preferred as technique scheme, described light trigger is 1-hydroxyl cyclic group phenyl ketone, benzophenone, benzoin dimethylether, 2,4, one or more mixtures in 6-Three methyl Benzene formyl diphenyl phosphate oxidation.
Preferred as technique scheme, described flow agent is for being polyether-modified dimethyl siloxane.
Preferred as technique scheme, described defoamer are a kind of in BYK141, BYK070, BYK 080.
Preferred as technique scheme, described coupling agent are a kind of in KH550, KH560, KH570, KH792, DL602, DL171.
Beneficial effect of the present invention is: should anti-zonedly write coating and be coated in the PET film surface and can strengthen its wear resistance, scuff resistance and anti-zoned ability, and extend the work-ing life of film.
Embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment, and this embodiment only, be used to explaining the present invention, does not form the restriction to protection domain of the present invention.
Embodiment 1: take anti-zoned each component of writing coating: the 38g urethane acrylate, the 25g Viscoat 295,30g toluene, 5.5g benzophenone, the polyether-modified dimethyl siloxane of 0.5g, 0.5g BYK141,0.5g KH550, after above each component is mixed, with coating machine, be coated on the surface of PET substrate layer, after solidifying, form the anti-zoned coating of writing.
Embodiment 2: take anti-zoned each component of writing coating: the 30g urethane acrylate, the 30g neopentylglycol diacrylate, the 32g ethyl acetate, 7g 1-hydroxyl cyclic group phenyl ketone, the polyether-modified dimethyl siloxane of 0.2g, 0.5g BYK070,0.3g KH560, after above each component is mixed, with coating machine, be coated on the surface of PET substrate layer, after solidifying, form the anti-zoned coating of writing.
Embodiment 3: take anti-zoned each component of writing coating: the 40g urethane acrylate, the 25g hexanediyl ester, 28g dimethylbenzene, 5g 2,4,6-Three methyl Benzene formyl diphenyl phosphate oxidation, the polyether-modified dimethyl siloxane of 0.7g, 0.9gBYK 080,0.4g KH570, after above each component is mixed, with coating machine, be coated on the surface of PET substrate layer, after solidifying, form the anti-zoned coating of writing.
The coating that makes is carried out to performance test, and sticking power, with reference to the GB9256-88 method, is judged the sticking power quality of filming by the method for drawing the lattice experiment.Coating hardness, with reference to the GB6739-86 method, uses the pencil hardness of the pencil scratch hardness instrument testing coating of filming.The antifraying property of coating resistance to marring thin-film material generally, with the Steel Wool test, utilizes Steel Wool to rub back and forth with constant speed at coatingsurface, and the anti-scuffing function of coating is defined as the required friction number of times of the obvious cut of article one.The results are shown in Table 1.
Table 1
By table 1, found out, coating prepared by the present invention has good sticking power and wear resistance, and anti-scuffing function is strong.
