Description
【Technical field】
This utility model is related to adhesive area, more particularly to a kind of processing procedure protection adhesive tape.
【Background technology】
With the fast development of electronic product, all-metal integration fuselage is one of element most popular at present.Quan Jin
Category integral machine body in process will through a series of surface treatment, such as polishing, plating, spraying, etch, radium-shine one
Serial complicated technique.These processes are necessary to need a material to carry out process protection to it, it is to avoid other non-processing positions
Scratch, damage.
At present, typically using protecting film such as PET protection film, PE protecting film, PVC protecting film, OPP protecting film to non-processing portion
Dividing carries out processing procedure protection.But, PET protection film is harder due to base material PET, it is impossible to stick turning and radian position well, no
Effective processing procedure protection can be played；Although and PE protecting film, PVC protecting film, OPP protecting film base materials are softer, due to glue-line tool
There is pressure-sensitive, in the process of sticking turning and radian position can not be perfectly sticked, cause alveolate residual, be so through one
The processing of row technique is peeled off and bubble marking residual is had after protecting film, affects product appearance and yield.By taking i Phone shell as an example,
Inside the shell because excessive turning and radian cause general protecting film completely to wrap up in the course of processing, so as to cause
Product yield is relatively low.
For problem above, a adhesive material that can very well wrap up shell turning and radian of present market in urgent need.
【The content of the invention】
The purpose of this utility model is to provide a kind of processing procedure protection adhesive tape, can wrap up shell turning and radian, is carried
High processing procedure protected effect.
The technical solution of the utility model is：
A kind of processing procedure protection adhesive tape, it is characterised in that including release film layer, pressure-sensitive adhesive layer, the heat-sensitive glue fitted successively
Layer and substrate layer.The adhesive tape is inviscid in laminating initial stage heat sensitive adhesive layer, and heated rear heat sensitive adhesive layer peel strength is improved, and reaches solid
Effect that is fixed and protecting.
Further, the thickness ratio of above-mentioned pressure-sensitive adhesive layer and heat sensitive adhesive layer is 1:1～4:1, appropriate thickness ratio just can make
Adhesive tape before heating after peel strength meet require.
Further, the rubberization thickness of above-mentioned pressure-sensitive adhesive layer is 5-20 μm, relatively low less than adhesion strength after 5 μm of high temperature, easily de-
Open, it is too high more than adhesion strength after 20 μm of high temperature, cause have cull to pollute after peeling off, or even be difficult to peel off.
Further, the rubberization thickness of above-mentioned heat sensitive adhesive layer is 5-20 μm, relatively low less than adhesion strength after 5 μm of high temperature, easily de-
Open, it is too high more than adhesion strength after 20 μm of high temperature, cause have cull to pollute after peeling off, or even be difficult to peel off.
Further, the thickness of above-mentioned substrate layer is 30-100 μm, and the substrate layer less than 30 μm is too soft, operability is poor,
It is excessive more than 100 μm of material deflections, it is unsuitable for the parcel to curved surface and turning.
Further, above-mentioned pressure-sensitive adhesive layer is resinae pressure sensitive adhesive or rubber-like pressure sensitive adhesive, such pressure sensitive adhesive heatproof humidity
Stable performance, and it is preferable to the adherence of material, and appropriate pressure can be easily bonding with material.
Further, above-mentioned heat sensitive adhesive layer is rubber-like heat-sensitive glue, because only that the heat sensitization temperature of rubber-like heat-sensitive glue
It is suitable for processing procedure protection, other temperature are too high or viscosity is too big, and heavy industry is not so good as rubber-based products.
Further, above-mentioned substrate layer be polyethylene film, polyvinyl chloride film, poly ester urethane thin film, polypropylene film,
Polybutylene terephthalate (PBT) thin film, this several thin film are softer, and followability preferably, can meet and preferably paste effect, subtract
The risk of few alice.
This utility model has following beneficial technique effect：
This utility model arranges heat-sensitive glue by adopting four-layer structure, between substrate layer and pressure sensitive adhesive, the laminating initial stage without
Viscosity, adhesive tape sticks shell inner side by vac sorb, is subsequently heated intensification, when temperature is promoted to base material softening temperature, base
Material starts to soften and colloid is still inviscid, now by the softer base material of vac sorb and the turning and radian portion of glue-line and shell
Position contact well, continues intensification colloid and starts to produce viscosity, and heat sensitive adhesive layer peel strength is improved, and reaches work that is fixed and protecting
With, adhesive tape can well stick on surface of shell after cooling, so as to avoid scuffing or damage in subsequent technique to it, can
Reduce bubble or the marking that adhesive material parcel shell turning and radian position produce, and the system conventional compared to integrated casing
Journey technique, parcel and protected area improve 10-25%, paste the incidence rate of bubble and reduce 15-40%, while it is difficult to reduce technique
Degree, yield can improve 10%-30%；This utility model not only can meet be not likely to produce between protecting film and clung body impact
Bubble that is attractive in appearance and using, also can reach perfect heavy industry effect, especially when occurring abnormal during pasting, when not heated
It is convenient to peel off and do not stay cull；This utility model is using softer polyethylene film, polyurethane film, polyvinyl chloride film, poly-
The materials such as ester urethane thin film, polypropylene film, polybutylene terephthalate (PBT) thin film are base material, and followability is preferable, Ke Yiman
Foot preferably pastes effect, reduces the risk of alice, further improves protected effect.
