Description
【Technical field】
The utility model is related to technical field of macromolecules, more particularly to a kind of adhesive tape.
【Background technology】
It is general at present in consumer electronic product to be bonded together two workpiece using viscose glue.On the one hand, viscose glue needs tool
There is preferable caking property to bond part with firm；On the other hand, during heavy industry, viscose glue need to have preferable easily tearing off property again；Glue
Glue had not only been needed with preferable caking property but also need to have preferable easily tearing off property.However, current common viscose glue is difficult both and takes into account.
The utility model application file of Application No. 201210563710.6 discloses a kind of adhesive tape, including substrate, formation
In the glue-line in the substrate and it is scattered in the micelle of the film surface, the adhesion strength of the adhesion strength more than the micelle of the glue-line, this
Adhesive tape is planted at the laminating initial stage, is easier to tear off adhesive tape；On the other hand, because the adhesion strength of glue-line is higher, after after gel bed permeability, adhesive tape
Cohesive force it is higher, so as to can ensure that the caking property of adhesive tape is preferable.
But, techniques disclosed above still can not meet wanting for the viscose glue that market is easily peelable to the initial stage, the later stage is more firm
Ask, it is therefore desirable to further to improve.
【Utility model content】
The purpose of this utility model is to provide a kind of adhesive tape, and initial stage peel strength is relatively low conveniently to do over again for positioning, passes through
The great lifting of peel strength reaches the effect of stabilization fixation after heating or placement.
The technical solution of the utility model is：
A kind of adhesive tape, it is characterised in that including release film layer, the first pressure-sensitive adhesive layer, the second pressure-sensitive adhesive layer fitted successively

Above-mentioned release film layer is silicon systems release film, is easy to the protection of gluing oxidant layer and can easily peel off.
Above-mentioned first pressure-sensitive adhesive layer includes thermally expanded microballoon and is distributed in the pressure sensitive adhesive of thermally expanded microballoon surrounding.
Microspheres (are called foam microspheres), are that a kind of shell is by being hydrocarbonization inside high molecular polymer (acrylonitrile copolymer)
Compound, is being heated in the case of (100-150 DEG C), and shell softens, and hydrocarbon is gasified by liquid, so that shell expansion increases
Greatly, remove to change the high molecular polymer of shell.Thermally expanded microballoon refer to by heating make expandable microspheres (being called foam microspheres) complete
Into the hollow particle of expansion process, therefore by that will not be expanded after heating, while also certain cushioning effect.
The particle diameter of above-mentioned thermally expanded microballoon is 5-30 μm, is easy to the filling of adhesive, and can reach the effect of buffering
Really, be difficult cluster between the requirement of outward appearance, microballoon while can meet.
The addition of above-mentioned thermally expanded microballoon is the 3-50% of pressure sensitive adhesive solid content, and this addition can both meet slow
Punching performance, can also ensure the adhesive property of adhesive.
The thickness of above-mentioned first pressure-sensitive adhesive layer is 10-50 μm, and the thickness of the second pressure-sensitive adhesive layer is 30-100 μm, in this interval
Thickness ensure the adhesive performance in adhesive tape later stage, and can easily control the cost.
The thickness of above-mentioned substrate layer is 10-100 μm, it is ensured that the operability and followability of product.
Above-mentioned substrate layer is the one kind in PET film, PVC film, PI films, TPU film, PE films, PP films etc., with
Gluing oxidant layer has good then performance, and the heavy industry performance in later stage is excellent.
The pressure sensitive adhesive of above-mentioned first pressure-sensitive adhesive layer is cross-linking type natural rubber pressure sensitive glue, such pressure sensitive adhesive resistance to ag(e)ing and resistance to
Warm nature can be excellent, with splendid adhesive performance.
The pressure sensitive adhesive of above-mentioned second pressure-sensitive adhesive layer is natural rubber pressure sensitive glue, synthetic rubber pressure sensitive adhesive, with the first pressure sensitive adhesive
Layer has good compatibility, and can be very good to be bonded the first pressure-sensitive adhesive layer and substrate layer.
The utility model has following beneficial technique effect：The utility model using release film layer, the first pressure-sensitive adhesive layer,
The four-layer structure of the second pressure-sensitive adhesive layer, substrate layer composition, by the initial bonding strength for controlling different pressure-sensitive adhesive layers, it is possible to achieve
Position or do over again in the laminating initial stage relatively low convenience of the first pressure-sensitive adhesive layer peel strength, the second adhesive layer glue after heated or pressure
The first pressure-sensitive adhesive layer is infiltrated into, makes the dramatic raising of peel strength of adhesive tape, reach fixed effect；The utility model addition is swollen
First pressure-sensitive adhesive layer of low adhesion glue-line obtained in swollen thermally expanded microballoon, in adhesive tape gluing initial stage peel strength lower one
Just positioning product can do over again in time, and peel strength lifting is larger after heated or pressing treatment, reaches the effect being permanently fixed；This
As each Rotating fields, after adhesive tape, cohesive strength is high using appropriate material for utility model, peel strength Datong District when temperature tolerance it is also big
It is big to improve, with fabulous die cuttability, it is to avoid during cross cutting the problems such as excessive glue, wire drawing；The utility model can be fitted by two-layer
Technique realize that process is simple, production efficiency is high, good in economic efficiency.
