Description
Technical field
The utility model relates to printing technology, and particularly a kind of printing overlay film that has scratch resistance, wear resistance to require is a kind of pre-coating film that adopts the extrusion composite technology technology to make.
Background technology
At present,, protect and improved all kinds of printed matter appearance and service life, therefore become one of important means that post-press finishing handles because coating technique has strengthened protection, decoration function to printed matter.Coating technique is divided into promptly film coating technique and pre-coating film coating technique, than promptly filming, pre-coating film has characteristics such as Environmental Safety, easy to operate, energy-efficient, excellent performance, it progressively improves at the market portion, along with the technological progress of overlay film industry, promptly film and to be substituted by pre-coating film.
Can be divided into light pre-coating film and inferior light pre-coating film according to the pre-coating film substrate surface to the reflex of light.Inferior light pre-coating film substrate surface is a diffuse reflection surface, has the characteristic of low-luster (generally 15%), high mist degree (generally 70%).Inferior light pre-coating film adapts to technologies such as the local UV glazing behind the overlay film, gold stamping, boiling hot silver, frosted, and have antifouling, moistureproof, prolong characteristics such as printed matter life-span, the surface matt effect makes it that artistic value and practical value more be arranged, be usually used in high-grade handbag, high-grade book cover, high-grade packing box, the packing overlay film of product modelled after an antique.But existing non-processing polypropylene pre-coating film can not be protected book cover, cover enduringly, and the surface is easily scratched by external force.The frequent contact surface of common inferior light pre-coating film can produce wearing and tearing, influences outward appearance, reduces protective effect.Therefore existing non-processing polypropylene pre-coating film product is frayed easily in print production and transportation, operating process, return of goods rate height, in addition, existing pre-coating film surface poor visual effect.
The utility model content
The purpose of this utility model is: a kind of Biaxially oriented polypropylene anti-scratching flat top pre-coating film is provided, behind surface coatings such as book cover, handbag, packing box, can improve its scratch resistance, anti-wear performance, increase persistence, strengthen visual effect again, improve product specification; Satisfy the client to overlay film after the requirement of product with waterproof, grease proofing, antifriction, anti-pollution, folding tension of strengthening printed matter.
The technical solution adopted in the utility model is: Biaxially oriented polypropylene anti-scratching flat top pre-coating film, comprise base material, intermediate layer and hot melt adhesive layer, and the width of base material, intermediate layer and hot melt adhesive layer is identical.It is characterized in that: base material is the inferior optical thin film of scratch resistance Biaxially oriented polypropylene (BOPP), and promptly base material is made up of inferior light polypropylene layer and scratch resistance coating.Wherein, the thickness of inferior light polypropylene layer is between 12～16.5 microns, and the thickness of scratch resistance coating is between 2～3.5 microns.What inferior light polypropylene layer adopted is the inferior optical thin film of Biaxially oriented polypropylene (BOPP).Evenly apply one deck scratch resistance coating at inferior light one side surface of inferior light polypropylene film and promptly obtain base material.The intermediate layer is polymine (PEI), and hot melt adhesive layer is ethene-vinyl acetate (EVA) PUR.The intermediate layer evenly is coated in the inferior light polypropylene layer surface of base material, even more compound one deck hot melt adhesive layer on the surface in intermediate layer.The thickness of base material is between 14～20 microns, and (coated weight is 0.009～0.011g/m to the thickness in intermediate layer at 0.01～0.03 micron
2) between, the compound thickness of hot melt adhesive layer is between 10～20 microns.
Technical scheme is preferably: the thickness of base material is between 15～19 microns, and (coated weight is 0.009～0.01g/m to the thickness in intermediate layer at 0.01～0.02 micron
2) between, the compound thickness of hot melt adhesive layer is between 10～15 microns.
The composite production line that utilizes extruder and equipment complex to form is coated in the intermediate layer on the inferior light polypropylene layer surface of base material, at last hot melt adhesive layer is compounded on the intermediate layer, produces Biaxially oriented polypropylene anti-scratching flat top pre-coating film.After the thickness of base material and hot melt adhesive layer carries out suitable combination, can obtain different products.Above-mentioned extruder and equipment complex and coating and combination process are that those skilled in the art know.
Ethene-vinyl acetate (EVA) PUR is a kind of solvent, moisture free solid meltability polymer of not needing; Be solid at normal temperatures, heating and melting becomes and can flow to uniform temperature, and the liquid of certain viscosity is arranged.Ethene-vinyl acetate after the fusion (EVA) PUR is light yellow or colourless.Ethene-vinyl acetate (EVA) PUR is become to be grouped into by basic resin, tackifier, viscosity modifier and antioxidant etc.At present, apply level ethene-vinyl acetate (EVA) PUR product and mainly rely on import, domestic no suitable other product of coating level.
Polymine (PEI) molecular formula is: [CH
2CH
2NH-] n, there is the product supply in Shanghai DiC Ink Co., Ltd, and our company adopts U.S.'s imported product.
The material of scratch resistance coating is a lot of at present, as: patent publication No.: CN101564720, in " preparation method of biaxially oriented polyester film surface wear-resistant scratch-resistant coating ", the biaxially oriented polyester film surface wear-resistant scratch-resistant coating material that provides; And for example: publication number: CN101466806, " scratch resistance on the polymer surfaces and the coating of wearing and tearing "; Publication number: CN1399667, the ultraviolet-ray curing composition that is used to prepare the scratch resistance coating that provides; CN101087858, " coating composition of the anti-scratch coating that can be shaped " that provides.
The beneficial effects of the utility model: the utility model Biaxially oriented polypropylene anti-scratching flat top pre-coating film, with the inferior optical thin film of scratch resistance Biaxially oriented polypropylene (BOPP) as base material, with the pre-coating film of ethene-vinyl acetate (EVA) PUR as hot melt adhesive layer, have high scratch resistance, anti-wear performance, even being streaked also by external force, the surface can not stay cut, the surface is honorable as new, promotes product specification, obtains better profit.Biaxially oriented polypropylene (BOPP) anti-scratching flat top pre-coating film constant product quality, and have environmental protection, safety, convenience, energy-conservation, efficient advantage, can satisfy some clients to overlay film after product requirement.Because sharpest edges are to have lasting resistance to marring, so its product will obtain extensive use more in fields such as book covers.
The utility model has adopted the inferior optical thin film base material of a kind of scratch resistance Biaxially oriented polypropylene, and there is the scratch resistance coating on the surface, adopts the compound generation Biaxially oriented polypropylene of hot pressing mode and PUR anti-scratching flat top pre-coating film again.Biaxially oriented polypropylene anti-scratching flat top pre-coating film can be protected book cover, cover etc. more enduringly; do not make it frayed and scratch, its persistence is the polyacrylic several times of non-processing, so this product is not frayed in print production and transportation, operating process; can reduce return of goods rate, promotion.And this scratch resistance film surface carried out inferior light and handled, and can improve product specification, strengthens visual effect, attracts client's attention, promotes value of the product.
