Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of permanent protective property foam tape, as shown in figure 1, including foamed cotton layer 1, the side of foamed cotton layer 1 adhesive layer 2, with
And it is covered in the release protective layer 3 on adhesive 2.When preparing this adhesive tape：The glue of precise thickness is first coated with release protective layer,
Adhesive layer is formed, dries by drying box, is bonded with the foamed cotton layer after sided corona treatment, after-combustion is made, in case using.
Above-mentioned adhesive layer 2 uses acrylic pressure-sensitive adhesivee or rubber pressure sensitive glue, it is preferred to use be oiliness marine glue.Need
It is noted that the thickness of adhesive layer 2 is preferably 0.01-0.1mm, herein in preferable thickness range, can meet to assemble
During requirement to different bonding performance, such as the inter-module having needs resetting, now by adjusting rubberization thickness just
The thickness deviation of foamed cotton layer itself can be compensated, will not be because of error when foam is die cut, and influence the uniformity of this tape thickness.
This tape applications ensure that two electronic product structural component gaps are consistent when the fitting of two electronic product structural components, and aesthetics is good,
And sealing is good.
Above-mentioned foamed cotton layer 1 uses closed pore waterproof foam, and its thickness is 0.05-3mm, density 50kg/m3-650kg/m3.Foam
Closed pore waterproof foam, using the foam of the density, resilience is suitable, will not " really up to the mark " also will not " excessively soft ", squeezed by foam
Pressure is filled in the gap of inter-module, to realize waterproof and sealing.Encapsulation operation simple and fast, cost are low.
Demonstrated through many experiments and practical situations, foamed cotton layer thickness control is the most in the range of 0.05-3mm
Reasonably, using this thickness and the foam of density, the dimensional stability of adhesive tape in production process can be ensured, and be easy to be die cut
Processing.Foam compresses and rebound performance is excellent, the gap that can be sufficient filling between component, therefore waterproof and dustproof effect is more preferable.
If foamed cotton layer thickness is less than 0.05mm, decrement caused by reality is minimum, it is difficult to the compressibility having by it
The extruding of glue-line and panel can be realized, it is therefore difficult to reach optimal sealing effectiveness jointly by extruding force and gumminess.
If foam thickness is more than 3mm, influence can be brought on the outward appearance of product, not only thickness increase is more, moreover, thicker foam is difficult
To realize more accurate cross cutting, the foamed cotton layer size qualification rate of production can be relatively low, and dimensional stability is poor, and production cost adds
Greatly, moreover, thicker foamed cotton layer decrement is larger, the stability of counter plate and its component also result in bad influence.
It is pointed out that foamed cotton layer, as base material, its thickness value should be in a continuous preferable numerical value model
In enclosing, the thickness of foamed cotton layer can just be selected according to being actually needed, be adapted to close between a variety of electronic structure parts
Envelope.Even in fact, being used under identical product, it is also possible to needs are selected foamed cotton layer thickness in certain scope,
Because foamed cotton layer has certain compressibility, sealing when its less mismachining tolerance in fact will not be to encapsulation impacts.
In the invention, the mismachining tolerance of foamed cotton layer can be adjusted by adhesive layer, preferably ensure that product
The uniformity of thickness.In addition, have certain compressibility just because of foam, its machining accuracy be difficult to control it is specific at one
, particularly accurate numerical value, if being an accurate numerical value by its thickness limit, production efficiency substantially reduces, and without appointing
What practical significance, is worthless.
Above-mentioned release protective layer 3 uses PEK release liners or transparent PET mould release membrance.Above-mentioned foamed cotton layer 1 is preferably steeped using PU
Cotton, EVA foams or PE foams.Color can be the black with the electronic product color-match to be encapsulated, grey, white etc.,
Preferred colors are black.
This adhesive tape is particularly suitable for use in the sealing between electronic product module, such as, it is necessary to rear shell and hand when mobile phone battery cover assembles
Good sealing, effective dust are respectively formed between the mainboard and mobile phone frame of machine；Further, since existing electronic product is to anti-
The demand more and more higher of water-based energy, therefore, the adhesive tape that the invention can be utilized to provide, mobile phone scuncheon is arranged on, with
Rear shell forms sealing structure.Meanwhile this adhesive tape can also be pasted around each electronic component surrounding on mainboard, when rear shell is assembled
After the completion of, the adhesive tape between rear shell and each electronic component forms single sealing structure, and mobile phone can not only realize splash waterproof, and
And can be soaked in certain depth water (under certain hydraulic pressure) a period of time, without soaking, such structure setting, significantly
The water resistance of mobile phone is improved, is effectively guaranteed the security that each important electronic component uses, complete machine water resistance pole
It is good.
During using this adhesive tape：According to the gap between component and the requirement to material, corresponding thickness and the glue of material are selected
Band, after foam tape is die-cut into the size that is required in drawing, separated type material is torn, by coated face (i.e. with adhesive layer
Side) it is Nian Jie with component (such as cell phone mainboard side), non-coated face and another component by mechanical means (such as with mobile phone battery cover
Surface compresses) it is fixed.Now, adhesive tape side is compressed by, opposite side bonding with component by foam compression rebound active force,
To reach the effect of the waterproof and dustproof of bilateral.Because foamed cotton layer side bonds, opposite side is to be squeezed in another assembly surface, because
This, when disassembling two structural member sealed against each other, foamed cotton layer will not be torn, and will not form cull.
In order to further improve water proof and dust proof ability, in an optional embodiment, as shown in Fig. 2 different in foamed cotton layer 1
Weak sticky glue-line 4 can be set in the side provided with adhesive layer 2, in order to form effective protection to the weak sticky glue-line, at it
Outside sets layer protecting film 5, and the diaphragm can use release liners or PET mould release membrances.In use, foam tape is die-cut to
After the size required in drawing, tear release protective layer, the side of adhesive layer is Nian Jie with component, weak sticky glue-line side with
Another component bonds, meanwhile, by the active force of foamed cotton layer compression rebound, realize tensioner of this adhesive tape between two components, energy
Enough realize splendid waterproof and dustproof effect.Now, foamed cotton layer side bonds, and opposite side is weak sticky bonding, therefore, is being torn open
When solving electronic product, it is highly susceptible to removing the adhesive tape between two electronic products, the foamed cotton layer of adhesive tape will not be torn, and be not easy to be formed residual
Glue.
Low sticky double faced adhesive tape or ultra-low viscosity double faced adhesive tape on the market can be used, screen is protected with being typically used in mobile phone
The viscosity of low sticky glue on cuticula is approximate.Traditional design of adhesive tape is all to consider how to improve viscosity, it is ensured that foam
Electronic product surface is securely bonded to, prevents it from coming off, also, is on the basis of secure adhesion, just realizes sealing.
But the drawbacks of so maximum is to remove operation to waste time and energy, and it is difficult to clean out, easily has glue residua in electronic product table
Face, after maintenance or dismounting, when carrying out sealing waterproof to electronic product again, due to there is the influence of glue residua, it is difficult to reliable
Waterproof and dustproof is realized, more or less meeting influences product aesthetics.
This product is exactly that reverse thinking considers, is bonded in foam with electronic product the defects of overcoming above-mentioned prior art
Side use weak sticky glue or superweak sticky glue, when foam is arranged on panel, foam be more closely similar to absorption in panel
On, the viscosity of strength is not produced between the two, is only the compressibility using foamed cotton layer, weak sticky glue-line is squeezed in panel table
Face, using the extruding force of foamed cotton layer and the weak viscosity of weak sticky glue-line itself, realize sealing well, not only waterproof,
Good dustproof effect, moreover, when needing to remove, it will not leave behind cull, it is at all unaffected during heavy industry, operating efficiency is improved,
And to greatest extent guarantee heavy industry when it is with reset condition surface cleanliness factor consistent, do not influence outward appearance.
In order to improve the performance of this product, in an optional embodiment, as shown in figure 3, can be in foamed cotton layer
Both sides be equipped with antistatic layer 6, specifically, the antistatic layer can use electrostatic prevention film.By adjacent in foamed cotton layer both sides
Foamed cotton layer sets antistatic layer, both without prejudice to the viscosity and sealing of this adhesive tape, meanwhile, also act good antistatic work
With.The electrostatic interference between electronic building brick is effectively raised, the reliability used of electronic product is improved, to a certain degree
On, it also avoid screen color distortion, the rate of breakdown of ghost image.
Foam tape provided by the invention is simple in construction, and use is reliable and stable, has good waterproof and dustproof performance, and
And can easily remove, cull is will not leave behind, very convenient product heavy industry, ensure that the quality of assembling product.
The preferred embodiment of the invention is the foregoing is only, is not intended to limit the invention creation, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc., the invention should be included in
