At present, body sticker be attached to vehicle body etc. flowing the carrier such as media and external wall on jet drawing material, such spray
Paint that tack of materials is good, anti-Japanese illumination aging.Common automobile body film product includes white glue body sticker and black glue body sticker, wherein, white glue
Body sticker:White calendering level pad pasting, good weather resistance, transparent pressure sensitive glue, plane paste excellent performance, 1 ~ 3 year validity period;
Black glue body sticker:Black calendering level pad pasting, good weather resistance, transparent pressure sensitive glue, plane paste excellent performance, made within 1 ~ 3 year
With the phase, indicated for advertisement, build and outer surface of automobile covers, paste, there is in light weight, service life length, usable solvent
Or Weak solvent spray drawing machine carrys out individual characteristic of creating pattern.
Traditional traffic allowance gum, mould release membrance use the release liners using wood-free paper as paper substrate.The release liners are in traffic allowance air brushing
Meeting nature abandons after fitting, causes to waste;And release liners of the wood-free paper as paper substrate are used, easily influenceed and rolled up by humidity
Song, print procedure paper injustice warpage is caused to scrape shower nozzle.Therefore, it is necessary to research and develop a kind of new traffic allowance gum.
The content of the invention
The purpose of this utility model is to provide a kind of new traffic allowance gum, has printing, the handling characteristics of printing concurrently.
To reach above-mentioned purpose, the utility model uses following technical scheme:
A kind of traffic allowance gum, including PVC air brushing layer, adhesive layer, silicone oil release layer, BOPET film layer, at BOPET surfaces
Layer, label film air brushing layer are managed, the lower surface of the PVC air brushing layer is bonded with the upper surface of adhesive layer, the following table of the adhesive layer
Face is bonded with the upper surface of silicone oil release layer, and the lower surface of the silicone oil release layer is bonded with the upper surface of BOPET film layer, institute
The lower surface for stating BOPET film layer is bonded with the upper surface of BOPET surface-treated layers, the following table of the BOPET surface-treated layers
Face is bonded with the upper surface of label film air brushing layer.
Further, the thickness of the PVC air brushing layer is 70 ~ 100 microns.
PVC air brushing layer is the milky white plastic pvc flexible film containing calcium powder or titanium dioxide filler, and color has this white and indigo plant
Point of white, gloss have bloom, dumb light other, and oil content is 25 ~ 28PHR, has printing clear, the fireballing feature of blotting, prevents
It is water-based strong, it is outdoor spray-drawing important medium.
Further, the adhesive layer is acrylate pressure sensitive adhesive, is divided into removable plastic pressure sensitive adhesive, not removable glue laminated by high movable
Quick glue, can be according to the appropriate glue class of environmental selection.
Further, the thickness of the adhesive layer is 15 ~ 25 microns.
Further, the composition of the silicone oil release layer is methyl vinyl silicone, and silicone oil release layer is very thin, thickness without
Method measures, and is typically represented with dry glue grammes per square metre:0.075 gram/m, even spread is complete through overbaking solidify afterwards, has and peels off
The characteristics of power is stable.
By the way that methyl vinyl silicone silicone oil is uniformly solidificated in BOPET film, film off-type force ensure that
Uniformity, and avoid and silicone oil transfer occur and cause the bad phenomenon of traffic allowance PVC air brushing layer printing blotting.
Further, the thickness of the BOPET film layer is 50 ~ 100 microns, has fabulous wearability, folding resistance, resists
The performances such as lancinating.
Further, the composition of the BOPET surface-treated layers is acrylic resin and isocyanate resin.BOPET surfaces
Process layer is very thin, and thickness can not measure, and is typically represented with dry glue grammes per square metre:0.4 ~ 0.5 gram/m.
PET film and mark after main component is the BOPET surface conditioning agents processing of acrylic resin, isocyanate resin
The adhesive force of label membrane coat significantly increases, and can prevent coating dry linting.
Further, the composition of the label film air brushing layer is acrylate and calcium powder, and calcium powder is filler, acrylic acid
Ester resin emulsion is phragmoplast.
Further, the thickness of the label film air brushing layer is 6 microns.
By being coated with label membrane coat in the BOPET film after the processing of BOPET surface conditioning agents, make BOPET film
As printing consumable material, you can for printing industry, be widely used in relief printing plate, intaglio plate, lithographic plate, screen painting.
The utility model has the advantages that:
1st, PVC air brushing layer, label film air brushing layer may be respectively used for solvent spray-drawing, printing.
2nd, wood-free paper base release liners are replaced using the BOPET film of coating silicone oil mould release, paper can be avoided the occurrence of and existed
Uneven warpage under different humidity environments and print the bad phenomenon for scraping shower nozzle.
3rd, label film air brushing layer is coated with BOPET film, can be used for printing industry, avoids the discarding wave of release liners
Take.
Traffic allowance gum of the present utility model has printing, the handling characteristics of printing concurrently.PVC air brushing layers can apply to open air
By force, the air brushing of Weak solvent wide format printer uses;Label film air brushing layer can be widely applied to relief printing plate, intaglio plate, lithographic plate, screen painting.Make
Used time, PVC air brushing layers are first printed, tear-off layer of PVC is remaining by silicone oil release layer, BOPET film layer, mark after adhesive layer is bonded
The film of label film air brushing layer composition can be used in printing industry.Air brushing layer, the coating of traffic allowance gum have printing, printing color
Clearly, the characteristics of reproducibility is high.
