Abstract
The invention provides an adhesive tape with a strap-shaped substrate material, which is used for wrapping a longitudinally extending object, particularly a conductor bundle or cable bunch. At least one side of the substrate material is spread with a special pressure-sensitive adhesive. The tape is characterized in that: the substrate material is formed by embossed PVC thin films; and the embosseddepth is 0.01 to 8mum, preferably 0.1 to 3mum.
Description
Technical field
The present invention relates to adhesive tape, especially be used for insulating and wrap up the adhesive tape of lead or cable, it has single or double gummed base material; And relate to this adhesive tape and bring the application of twining wrapping and harness (especially in motor vehicle such as the automobile) lead and cable as insulating tape or wrapping.
Background technology
Insulating tape and cable wrap are made of the plasticized PVC film of single spreading usually.This class also is used for electrical lead is wrapped up into bunch of cables in automobile based on the adhesive tape of PVC flexible film.If originally to original adhesive tape of developing as insulating tape, it is very important to improve electrical insulation capability, so this adhesive tape just must be realized other function now, for example some unit cables are tied up and are permanently fixed more stable bunch of cables, prevent that perhaps cable from suffering the environmental influence of machinery, heat and chemical aspects.
Even in today, most these type of bunchs of cables still wrap up with manual mode.And when manual when cutting off common flexible film adhesive tape, cause the carrier thin film overstretching easily, form the waviness that is difficult to reliably cling and tear the edge.
Retraction after the overstretching may cause bonding end to peel off (professional is alice (Flagging)).For alice, be generally understood as the tendency of the terminal perk of bandage of parcel.Reason is the comprehensive action of bonding force, carrier rigidity and the bunch of cables diameter of tackiness agent.
Not only just the perk phenomenon can occur, and the design of special cable bundle also can cause this phenomenon because of the improper use of film adhesive tape.Especially peel off tendency in the terminal existence of the adhesive tape that is directly adjacent to bunch of cables vary in diameter part.Bunch of cables manufacturers avoids this problem in various mode.For example common practice is to finish parcel on each bigger parts of diameter.In addition, also attempt additional high elastic force pressure and make good especially fixing of adhesive tape end.But all these solutions all need additional overhead when the parcel bunch of cables, and this should be avoided as far as possible.
Therefore, on the back side of adhesive tape, higher clinging power to be arranged usually, to avoid occurring alice.And higher clinging power usually means that tackiness agent is very soft, and this can cause tackiness agent to overflow from the rubber roll side again.The professional is called strike-through with the sticking viscosity of this side.
In order to satisfy the environmental requirement of upgrading, had since the several years trend of avoiding in the adhesive tape production process, using solvent.Especially can not volatilize solvent (professional being VOC, i.e. volatile organic compounds) at the employed product of auto industry field strong request.
Relatively difficulty and expense are bigger owing to give PVC flexible film coating hot-melt adhesive, so manufacturers all uses water accack to address this problem.
Yet, to compare with solvent-based systems, these moisture tackiness agent and PVC flexible film bonded clinging power are less.For some adhesive system,,, in the time the alice phenomenon can not occurring, also can use the less tackiness agent of clinging power for the consideration of cost aspect although can evade this shortcoming by proper formula.

Embodiment
According to this, the present invention relates to be used for especially wrapping up the adhesive tape of longitudinal extension article such as bundle conductor or bunch of cables, this adhesive tape has the band-shaped substrate material, described base material single face at least scribbles pressure-sensitive adhesive, and base material is made of embossing PVC film, the embossing degree of depth is 0.01 μ m～8 μ m, is preferably 0.1 μ m～3 μ m.
The embossing degree of depth is poor (following also will explain in detail measuring the required detection method of the embossing degree of depth) of thickness of calculating according to weight per unit area and the thickness that utilizes the detecting thickness instrument to measure, between 0.01 μ m and 8 μ m, the style of embossing is unimportant in principle.The embossed film that preferably has vertical or horizontal, continuous or discontinuous lines.
The shape of embossing and the degree of depth play favourable influence to the kindliness of film when the wrapping cable.The film embossing also helps stretching, because at first can extrude the air that is contained between film and the cementing agent under tension force.In addition, so also can realize less uncoiling power, thereby help handling adhesive tape with hand.
The professional is unexpected to be found: the key factor of avoiding alice is not to be clinging power (below will explain in detail measuring the required detection method of alice) on tackiness agent self back side, but exists between the embossing degree of depth and alice characteristic and direct relation that clinging power has nothing to do.
In addition, unexpected discovery also has: with regard to different film formulation and all thinkable adhesive formulations, all can prove to have this effect.
According to first kind of useful embodiment of the present invention, base material by thickness be 40 μ m～350 μ m, the PVC film that is preferably 70 μ m～150 μ m constitutes.
Adhesive tape of the present invention can be made with the film that contains the conventional monomeric plasticizer in 5～60phr scope, this monomeric plasticizer for example is dioctyl phthalate (DOP) (DOP, two (2-ethylhexyl) phthalic ester), diisononyl phthalate (DINP), Di Iso Decyl Phthalate (DIDP), three (2-ethylhexyl) trimellitate (TOTM); And the same available film that contains the typical polymers softening agent in 10～70phr scope is made, this polymeric plasticizer for example is that hexanodioic acid, sebacic acid, nonane diacid, phthalic acid and dibasic alcohol are as 1,3-butyleneglycol, 1,2-propylene glycol, 1,4-butyleneglycol, 1, the polyester (M of 6-hexylene glycol and other glycol
rBe about 1800～13000) make.Also can produce film, described phosphate plasticizer such as di(2-ethylhexyl)phosphate benzene toluene ester (DPCF), diphenyl octyl phosphate (DPOF, (2-ethylhexyl) diphenyl phosphoester) or three (2-ethylhexyl) phosphoric acid ester (TOF) with typical phosphate plasticizer.
Can use the mixture that contains one or more the above-mentioned type softening agent equally.
The K value of PVC powder can change in broad range equally.So use range does not have much influences at the PVC of 40～90K emulsion powder or suspension powder to the improvement of alice characteristic.
But the PVC that the K value is bigger is because thermostability is higher and preferred, and for example the K value is 78 PVC emulsion.For example at Hand book of PVC formulating (editor E.J.Wickson, J.Wiley﹠amp; Sons, 1993) in or at PVC:Production, Properties and Uses has put down in writing this class material and working method thereof in (G.Mattews, The Institute of Materials, 1996).Therefore, the K value of film especially should be between 75～80 preferably between 60～90.
Also can be with all other additives of PVC film (as stablizer, for example at " the Plastics Additives Handbook " of Hanser press (the 5th edition) or John Wiley ﹠amp; The stablizer of being put down in writing in " the Handbook of PVC Formulating " of Sons press) adds among the adhesive tape of the present invention, and can not have any impact the alice characteristic.
For avoiding the PVC film to suffer pyrolytic damage (for example embrittlement) in the process that adds man-hour or use as adhesive tape, it is desirable adding stablizer such as diphenyl thiourea material.According to a kind of preferred implementation of the present invention, film contains stablizer.Be applicable to the especially tin compound class stablizer of adhesive tape of the present invention, preferably those allowances are used for the tin compound stablizer of food packaging film, for example dibutyl tin-two-(2-ethylhexyl mercaptoacetate).Equally also can use the stablizer of leaded or cadmium, but these stablizers are for the reason of toxicity and environment aspect, less use.The content of stablizer is between 0.3～10 weight part (in 100 weight part PVC polymkeric substance) for example, in order to reach higher thermostability, are at least 0.7phr, preferably are at least 1phr (in the shared weight part of 100 weight part PVC).
Common other additive such as filler, pigment, impact modifier, lubricant and/or processing subsidiary material (Verarbeitungshilfsmittel) in the PVC film (Paraloid K 120 ND for example, Rohm﹠amp; Haas) also can be used for making the carrier thin film of adhesive tape of the present invention.In " Kunststoff-Handbuch-Polyvinylchlorid 2/1 " (the 2nd edition, Hanser Verlag.) the 6th chapter, put down in writing common additives.Use the montanic acid ester type waxes
As preferred lubricant, its consumption is favourable with 100 weight part PVC polymkeric substance timing with 2～5 weight parts.
Preferably on rolling press, prepare carrier thin film, carry out drawing-off especially again with high temperature or low temperature process.Be higher than in temperature under 95 ℃ the condition, go up with the film drawing-off repeatedly, make that thickness is corresponding to be reduced by the roller speed that increases gradually at roll-type drafting machine (Rollenstrecke).Film can also be widened (KOBRA slightly
Technology).Luvitherm
Technology is particularly suitable for adhesive tape of the present invention, because also can handle higher K value without a doubt.For example at Kunststoff-Handbuch (Carl-Hanser Verlag.), just put down in writing Luvitherm on 240～243 pages in chapter 2 polyvinyl chloride the 1st chapter
Technology.This technology is made up of two processing steps, with lower temperature calendering polyvinyl chloride, promptly by roller it is pressed into film in the fs, carries out the short period of time with comparatively high temps and handle in subordinate phase, will have the film sintered of widget intensity very.Also can hard PVC be processed into film, but this technology only is suitable for lower K value with blow molding process.
The PVC base material is single spreading at least.Can use the tackiness agent of all common types, for example with tackiness agent based on aqueous polyacrylic ester, polyisoprene and/or polyisobutene, General Purpose Rubber or acrylate.This type of rubber for example can be the homopolymer or the multipolymer of iso-butylene, 1-butylene, vinyl acetate, acrylate, divinyl or isoprene, and the main prescription that uses based on acrylate, divinyl or isoprene.
Typically the cementing agent based on acrylate can be polymerized with alkyl acrylate that contains 4～17 carbon atoms and/or methacrylic ester.Can add the suitable comonomer that has functional group's (as carboxyl or hydroxyl) by polymerization, improve mechanical characteristics and adhesiveness targetedly.
Can use solution, be coated with the tackiness agent of all these types with dispersion or hot melts form.The selection of coating method is to the not significantly influence of alice characteristic.But should preferably use the water accack system.
Can be at 10～50g/m
2, especially at 15～30g/m
2The suitable tackiness agent of coating in the amount ranges.
Clinging power on the back side can be at 0.2～3N/cm, preferably can change in 0.5～1.5N/cm scope, can not influence the alice characteristic.
For optimization characteristics, one or more additives can be added, as tackifier (resin), softening agent, filler, pigment, UV light absorber, photostabilizer, fire retardant, antiaging agent, light trigger, linking agent or crosslinking reaction promotor in used Autoadhesive.For example, tackifier can be that hydrocarbon resin is (for example based on unsaturated C
5-or C
9-polymer of monomers); The terpene phenolic resin; Polyterpene resin based on raw material such as α-Pai Xi or beta-pinene; Aromatic resin, as coumarone-indene resin, the perhaps resin of styrene-based or alpha-methyl styrene, as rosin and secondary species thereof, for example nilox resin, dimerization colophonium or esterified rosin, for example with the reaction product of ethylene glycol, glycerol or tetramethylolmethane, or the like.Preferred use does not contain the resin of two keys of easy oxidation, as terpene phenolic resin, aromatic resin, especially preferred resin, for example hydrogenated aromatic resin, hydrogenation polycyclopentadiene resin, staybelite derivative or hydrogenation polyterpene resin by the hydrogenation reaction preparation.
The filler and the pigment that are suitable for for example have carbon black, titanium dioxide, lime carbonate, zinc carbonate, zinc oxide, silicate or silicic acid.The suitable softening agent that can mix for example has aliphatics mineral oil, alicyclic mineral oil and aromatic series mineral oil; The diester of phthalic acid, trimellitic acid or hexanodioic acid or polyester; Liquid rubber (for example paracril or polyisoprene rubber); The liquid polymerization product of butylene and/or iso-butylene; Acrylate; Polyvingl ether; With tackifying resin, wool wax and other wax or liquid silicone resin is the liquid resin or the soft resin of base-material.
Linking agent for example can be isocyanic ester, resol or halogenated phenols urea formaldehyde, melamine resin and formaldehyde resin.The crosslinking reaction promotor that is suitable for for example has maleimide, allyl ester such as triallyl cyanurate, the polyfunctional group ester of acrylic or methacrylic acid.
Antiaging agent for example can be a sterically hindered phenol, and the sterically hindered phenol of known commodity Irganox by name is wherein arranged.
It is favourable forming crosslinked, holds sticking (holding power) because can improve, and can reduce the distortion tendency (flexible or formation cavity be also referred to as space) of coiled material in depositing process.Also can reduce tackiness agent excessive (strike-through), promptly at the no glue side of coiled material and be spirally wound on adhesive tape around the cable and do not have in the glue limit and overflow.Hold the sticking plasticizer loading that also depends on adhesive component and film, be preferably greater than 150 minutes.
Tackiness agent can vertically be painted ribbon along adhesive tape, and strip width is less than adhesive band base.Decide on applicable cases, also can on base material, apply a plurality of parallel tackiness agent bands.
The position of band on base material can be selected arbitrarily, preferably is arranged on certain one side of base material.Preferably with adhesive coated on whole of base material.
Can have at least one to hide bar on the adhesive coating of base material, this hides bar or these hide bar along the adhesive tape longitudinal extension, and the rubber cover adhesive coating layer 20～90%.
According to a kind of preferred implementation of the present invention, just in time be one and hide bar on adhesive coating.
The position of band on adhesive coating can be selected arbitrarily, preferably is set directly on a certain vertical limit of base material.Obtain by this way along the adhesive tape longitudinal extension and with the isolated gluing band in another vertical limit of base material.
If adhesive tape is used for coating bunch of cables, its mode is to make adhesive tape center on the bunch of cables spiral motion, then can wrap up bunch of cables like this: make tackiness agent on the adhesive tape only adhere to adhesive tape from one's body, and article do not contact with tackiness agent.
Because any tackiness agent of shortage is fixing to cable, Bao Zha bunch of cables has very high snappiness like this.Therefore, also be like this even can obviously improve its bending property one when mounted at narrow path or sharp bend position.
If with adhesive tape to be fixed on to a certain degree on the article, then can coat like this, make a gluing band part adhere to adhesive tape from one's body, another part then adheres on the article.
According to the favourable embodiment of another kind, band is placed on the adhesive coating centre, thereby forms two gluing bands on vertical limit of base material along the adhesive tape longitudinal extension.
For adhesive tape being wrapped in around the bunch of cables reliably, economically in above-mentioned spiral motion mode, and prevent that formed sheath from sliding, these two the gluing bands that are each positioned on the vertical limit of adhesive tape are favourable, especially when wherein narrower than second a band usually band is used as sealing as second band of assisting fixture and broad.By this way adhesive tape suitably is adhesive on the cable, thereby prevents that bunch of cables from sliding, and still keep snappiness.
In addition, also have some that one or more cover strip is placed embodiment on the adhesive coating.As long as when it comes to a cover strip, the professional will associate so, and many cover strips also necessarily can while rubber cover adhesive layer.
The scope of this cover strip rubber cover adhesive coating layer is preferably altogether between 50～80%.Diameter according to applicable cases and bunch of cables is selected level of coverage.
Described percentage value is the cover strip width and the ratio of base material width.
Especially preferably leave the tackiness agent band that one or two total width is total up to 20～50% base material width.
Can be used as film that especially is usually used in the cable cladding applications (for example polypropylene film of polyethylene film, polypropylene film, uniaxial orientation or diaxial orientation, polyester film, PA film and other film) or PVC that cover material is used based on polyolefins, preferred plasticizer content 20 and 60phr between film.
Advantageously between carrier thin film and tackiness agent, use undercoat to improve the clinging power of tackiness agent on film, thereby avoid in the uncoiling process, tackiness agent being relayed on the film back side.About the illustrative examples of the tackiness agent commonly used of adhesive tape and barrier coat and undercoat as consulting " Handbook ofPressure Sensitive Technology (pressure sensitive adhesive technical manual) ", D.Satas (the 3rd edition).
Can be used as known dispersant system that undercoat uses and solvent system for example has rubber based on isoprene or divinyl, thermoprene, and paracril especially.Isocyanic ester as additive can improve clinging power, and in the slip resistance that after internal diffusion, can improve tackiness agent.
Can apply one deck coating at the base material back side in case of necessity and adjust uncoiling power.
The coating (can mix other polymkeric substance in case of necessity) that can apply known release agent realizes breaking away from effect.For example can use stearyl compound (for example urea that constitutes of the stearyl compound of polyvinyl stearyl carbamate, transition metal such as Cr or Zr, polymine and stearyl isocyanic ester, polysiloxane (for example as contain the multipolymer of urethane or as polyolefin-based graft copolymer), thermoplastic fluoropolymer.Stearyl refers to carbonatoms and is at least 10 all straight chains or branched-chain alkyl or thiazolinyl, for example octadecyl.
In order to obtain the tearable fragility of good craft (Handeinrei β barkeit), when making roll of tape, generation can be examined under a microscope the coarse cutting edge of crackle, and these crackles promote to tear.This especially can use blunt or certain zigzag rotary cutter to squeeze and cut, and perhaps uses fixed blunt edges to carry out rewinding and cuts (Abstechschnitt) and realize this effect.Because thickness is little and flexible tendency is little, thus 33～100m coiled material continuity length can be obtained without a doubt, and traditional product has the smaller length of 10～33m usually.
Adhesive tape of the present invention preferably has color, especially is black.Color is managed to make do in film, adhesive layer and/or the undercoat, perhaps before adhesive coating, afterwards or in the coating procedure color is imprinted on the film.
The basement membrane of adhesive tape and base material are said on the whole and can be contained fire retardant.Can use not halogen-containing material, these materials for example are the carbonate or the oxyhydroxide of aluminium, calcium or magnesium, for example borate, for example filler of stannate and so on for this reason; The nitrogen based flameproofing of melamine cyanurate, Dyhard RU 100, red phosphorus, organic or inorganic phosphoric acid salt such as polyphosphate or bulky amine such as HA (L) S level bulky amine and so on for example.Require to use bromated fire retardant when very high, as hexabromocyclododecane, poly-Dowspray 9 or preferably use two (penta-bromophenyl) ethane.The decabrominated dipheny base oxide can be used, antimonous oxide (Sb can be used in addition
2O
3).
Owing to have an above-mentioned advantageous feature, this adhesive tape can be used for insulation, parcel lead or cable very with flying colors.Advantageously be suitable for wrapping up the bunch of cables in longitudinal extension article, the especially automobile in addition, adhesive tape can be extended along spiral-line around the longitudinal extension article at this moment, perhaps axially wrapping up the longitudinal extension article with adhesive tape.If according to the regulation of LV 312 (in January, 2006 version, article 5.5), under temperature more than 100 ℃, the complex body that cable and adhesive tape constituted was deposited to 3000 hours, then around the bent spindle cable, then when being bonded in the cable that has the PVC coating layer and have on the cable of polyolefine coating layer, adhesive tape also can not destroy these cables especially.
The cross section of bunch of cables shown in Fig. 1, bunch of cables is made of the unit cable that is bundled together (7), and is surrounded by adhesive tape of the present invention.Make adhesive tape center on the bunch of cables spiral motion.
Shown in look out two circle adhesive tape I and II on the bunch of cables cross section.Other circle extends in the past left, does not draw here.
On adhesive coating (4), there is one to hide bar (5), thereby produces a strip of adhesive (6) along the adhesive tape longitudinal extension.The non-gluing segment of adhesive tape (11,21,23) alternately occurs with gluing segment (12,22,24).(sections 22,24 is opposite with exposed adhesive 12, can't see from the outside, and, therefore with darker shadow representation).Coat bunch of cables like this, gluing band (6) is glued fully be posted on the adhesive tape.Not bonding with cable (7).
" adhesive tape " of the present invention this general term comprises all planar products, as the film of two-dimensional development or film fragment, length direction launches and width is limited band, strap section, die-cut, label etc.
Detection method
In temperature is that 23 ± 1 ℃ and relative air humidity are to measure under 50 ± 5% the detection atmosphere.
All put down in writing the common methods of laboratory scale mensuration alice characteristic in the technical specifications of different automobile manufacturing companies.At this moment, standard is to make a sample that is made of 5～25 unit cables with same diameter or different diameter.Covering material of cable is abideed by the temperature grade of adhesive tape to be tested.Use adhesive tape to be tested to wrap up these cables then, make and respectively enclose overlapping 50%.The sample that will obtain like this places under the different temperature and envrionment conditions then, and then the axle around a diameter 80mm makes its bending.And then assessment alice situation.This alice test is very inresponsive, and many adhesive tapes that do not show defective in this test process alice can occur in actual application.
Therefore researched and developed a kind of novel test method that when making bunch of cables, can adjust situation.Give 13 general grade 0.85mm of commerce that are about 2 meters for this reason
