Description

Adhesive tape with the carrier that constitutes by fabric
The present invention relates to have the adhesive tape of the carrier that constitutes by fabric.
Is age a kind of in the rolling self-adhesion system of type at most by Woven textiles as solid support material and from the fabric adhesive tape that the layer that the gummous substance single face applies is constituted.The fabric adhesive tape at first is applied in the medical field, in developed the soft pvc insulation tape that partly is used for the cable wrapping the later half century in last century in automobile industry.Handiness, conformability (Anschmiegsamkeit), high mechanical strength and have simultaneously with hand laterally can be lancinating the combination of fabulous performance greatly enlarge range of application.The fabric adhesive tape can be used to wrap up, repairs, covers, fixes, mark etc. and need not scissors, cutter or other auxiliary means and can suitably tear with hand.Therefore described adhesive tape becomes general-adhesive tape (so-called " multi-functional adhesive tape " or " general utility functions adhesive tape "), and it can be bonded on a large amount of base material (no matter this base material is a polar or nonpolar, coarse or level and smooth) and be used for nearly all possible application scenario.
Gummous substance is almost completely by natural rubber or synthetic rubber formulation.Reason (natural rubber is first kind of available chief component from gummous substance of industry) except historical aspect, particularly, natural rubber or synthetic rubber are that equilibrated and the best are applicable to such general adhesive tape at the bonding technology aspect of performance, and wherein said bonding technology performance relates to clinging power, sticking power and cohesive force.Closely the textiles of braiding is as solid support material, and wherein the textiles preferred source is from (modification) natural fiber, for example cotton, short rayon fiber element, viscose yarn etc.
At first, the fabric adhesive tape of uncoated fabric (raw fabric or yarn dyeing cloth) only single face apply preparation with gummous substance.Yet the rubber gummous substance on the back side is because loose porous woven fabric structure is easy under attack.Oxygen, excitor substance for example solvent etc. almost can enter the rubber gummous substance in the clear.So and simultaneously also in order to protect fabric, plastic coating is coated in the upside of adhesive tape.Three types fabric adhesive tape is arranged according to product configurations:
● five-star product utilization has 70～150g/m basically 2The weight per unit area and the order of magnitude are 100～250 per square inch the close weaves of sieve mesh (the silk thread sum on per inch warp-wise and the broadwise), this close weave has the plastic coating of most of colored PVC of being derived from, acrylate, urethane or analogue, and this coating is applied by dispersion or organosol single face and forms.This product originates from Central Europe and this product prepares in Central Europe basically.The example of such " senior adhesive tape " is tesa
Figure BPA00001276469800011
4651.
● originate from the fabric adhesive tape in Asia previously, this fabric adhesive tape has the crosslinked fabric of lighter, loose 40～100 sieve meshes, and extruding has prepared the PE-film of 50～200 μ m on this fabric.Fabric and film mainly form stablizes tough mixture.Because its location at price and aspect of performance is called it " middle rank ".Tesa
Figure BPA00001276469800021
4688 can be used as example.
● so-called " fabricbase adhesive tape (the Duct Tapes) " that be derived from the North America is used widely in the whole world." fabricbase adhesive tape " used has 15～40g/m 2Very loose fabric, multiple layer fabric (Gelege) or the knitted fabrics (Gewirke) of 25～40 sieve meshes of weight per unit area, by part from gummous substance lamination on fabric, multiple layer fabric or knitted fabrics colored basically and opaque PE-film.The weather resistance of the carrier complexes of being made up of film and textiles is only by the bounding force and the stability to aging decision of gummous substance.This kind fabric adhesive tape is in minimum class and use on price fabric adhesive tape color all is silver color basically.The example of common commercial fabricbase adhesive tape is tesa
Figure BPA00001276469800022
4662.
The common total thickness of such adhesive tape is 200～400 μ m, and wherein the gummous substance layer is approximately 50～250 μ m, and this adhesive tape is to be designed for internal application (Innenanwdndung) from textural seeing in principle.
But this class adhesive tape as general adhesive tape also is used for outdoor application (Au β enanwendung).Because the following defective that causes adhesive tape to damage and damage up to fully will appear in such adhesive tapes of effect such as light, direct solar radiation, humidity, heat, microorganism:
● the rubber gummous substance with elastomerics reactive double bond under the effect of ultraviolet ray and ozone with destroyed and lose its original bond properties.
● the fabric that is made of cotton, viscose yarn, artificial silk etc. will be subjected to the attack of microorganism.These will rot for the composition that the mechanical property of adhesive tape plays a decisive role under the condition that humidity, heat and light exist.
● the water absorbed dose in the fabric that the receptivity that spins causes causes expansion, thereby causes mixture reduction and loss of strength.
Up to now, the trial of the research of senior general-fabric adhesive tape (so-called " outdoor adhesive tape ") of being suitable for long-term outdoor application is not all achieved success or only obtain circumscribed success.
At US 3,853, but put down in writing the more expensive fabric adhesive tape of a kind of high-grade price among 598 A1, it has the acetate viscose yarn-fabric of 200～250 sieve meshes closely.This fabric disposes polyacrylic ester-the first layer, applies the gummous substance of synthetic rubber and natural rubber on this first layer.Fabric with very high grit number has determined this adhesive tape to have good and the tearable fragility of hand very easily with the fabric configuration with polyacrylic ester-the first layer.But do not point out that this adhesive tape has outdoor suitability.Selected gummous substance and particularly illustrate that based on the not protected fabric of the upside of modified natural fiber it does not have outdoor suitability.Only be used for medical field, i.e. internal application in particular.
Put down in writing a kind of technology adhesive tape among EP 1 548 080 A1, especially for the technology adhesive tape of building field.Though be arranged on the strip-like carrier as the gummous substance to atmospheric stability with ultraviolet ray-crosslinked acrylate gummous substance, paper also has film, fabric or the carrier of the non-woven that is made of PE, PP or PET makes this technology adhesive tape be unfavorable for outdoor application.This technology adhesive tape does not possess the essential horizontal easily tearable fragility of hand of general adhesive tape.In addition, have following potential risk for ultraviolet ray-crosslinked acrylate gummous substance: the crosslinked action that under the effect of sunlight, has stopped in the preparation process will proceed and therefore during use the adhering technique performance will have negative change.
Put down in writing a kind of height of being made up of polyester multifilament fabric closely in EP 1 736 582 A1, it has fabulous water-repellancy and is used for rain gear and similar articles.The maximum unit area weight that has is 45g/m 2Such carrier bring too thin for all-purpose gum and can not satisfy client for of the requirement of general fabric adhesive tape about sense of touch and visual appearance aspect.And lack guidance about the tape applications aspect.
Also use non-woven (non-woven fabrics) to replace fabric for the reason of cost and performance.In corresponding preparation, use the PET-fiber or-macrofiber realize resistance to atmospheric corrosion and even realize the tearable fragility of good hand (for example referring to EP 0 389 212 A1 or EP 0 410 674 A1), but because its physical strength is less, such system is not to be the selection that is used for general fabric adhesive tape.Though can also improve (as being recorded among EP 1 124 680 A1) by processing macrofiber or multiple layer fabric (Gelege), but preparation comparatively trouble and therefore this preparation be that price is more expensive, the performance of this carrier does not approach the valuable characteristic performance of fabric.
For example be recorded in US 4,705,715 A1, US 4,654,254 A1, WO 2006/107054 A1, JP 2,003 253 543 A1, the fabric adhesive tape of the known PE-coating among EP 0 848 048 A1 or DE 602 17 908 T (on seeing: PE-thin film layer or be squeezed on the fabric or be laminated on the fabric) changes on product configurations to some extent, but in general this fabric adhesive tape is with regard to the state of PE-film, physical strength has obvious defects with general-fabric that the gummous substance of ultraviolet ray-stability and use is compared required resistance to atmospheric corrosion.
Put down in writing a kind of industrial gummed tape in DE 20 2,004 019 761 U, it is mainly as the wrapping of the cable in automobile industry adhesive tape.On textile carrier, apply a kind of plastic layer, wherein this textile carrier for example is non-woven, fabric or velvet, and this plastic layer is made up of urethane (specifically by thermoplastic polyurethane (TPU)) and is carried out coating with standard gummous substance common in this Application Areas.Obtain a kind of textiles adhesive tape of waterproof thus, this textiles adhesive tape has good wear resistance, good inhibition noise and good resistance to medium, and this is favourable to required purposes.But not only starting material TPU has determined that this preparation is that price is more expensive and will go wrong when the general adhesive tape when it, and special preparation makes its performance that is suitable for the cable wrapping make this textiles adhesive tape be used as general adhesive tape in the zone out of doors to seem not to be wisdom.
The product configurations of this invention makes product not have UV stable (clearly being recorded among the embodiment 1 (fabric adhesive tape)), and does not have the tearable fragility of competent hand.For technicians, not have the tearable fragility of competent hand be in accordance with expectation to such PU-coating.30～40% tear when elongation in described embodiment 1, the carrier that is made of fabric and PU-coating are softish and resilient so, tear to such an extent as to just torn with linear edge before adhesive tape reaches overstretching when tearing with hand normally.
Put down in writing a kind of concrete adhesive tape that is used for long-term outdoor application in WO 03/097758 A1, this adhesive tape experience in the resistance to atmospheric corrosion test of ASTM G155 has less than 10% gummous substance residual after 500 hours.Importantly be positioned at the multilayer PE-plastics film on the upside, this film contains the light stabilization additives of as many as 35%.Not special record other the adhesive tape composition for example 10～90 grid of meshes cloth (scrim) also have from gummous substance.Therefore supposition realizes uvioresistant in large area by the multilayer film on the upside, will cause the gummous substance of adhesive tape the change of not expecting to occur but oxygen, ozone equal the attack of edge.Will occur the slight crack of the typical edge abrasion of fabricbase adhesive tape in addition in the carrier structure that the grid cloth of described multilayer PE-film thick by 50～100 μ m and 10～90 mesh is formed, itself and senior fabric adhesive tape are not inconsistent.The light stabilization additives of high level also has multilayer film structure will cause corresponding higher preparation cost in addition.
In EP 1 074 595 A1, put down in writing a kind of polyester-fabric adhesive tape, this polyester-fabric glue by concrete spinning and definite woven fabric structure (maximum value of vertical silk thread fiber number of every unit of length is 2500dtex/cm) and particularly by adhesive coating stationary warp (Kettgarn) thus make that this adhesive tape is that hand is lacerable.Therefore must satisfy special condition here, be less than 10N thereby reach horizontal anti-resistance to spalling at least.The technician can recognize from the description of yarn parameter and fabric parameter that a kind of light fabric (is significantly less than 100g/m 2), this light fabric self has not only had less intensity by reducing weight per unit area curiously, but is that hand is lacerable by this light fabric of adhesive layer (it is stationary warp on the position of warp thread) in addition.Here will can lancinating performance connect less than tear strength and the hand of 10N mistakenly in addition.In practice, except above-described tear strength, the power that is used for initially tearing carrier also is very important for the tearable fragility of easy hand, be used for initially tearing carrier the tensile property of advocating to be subjected to other parameters such as carrier, use tailoring technology and cut out influences such as article, in the disclosure literary composition, can not find the information about in this respect.
In DE 10 2,005 044 942 A1, put down in writing a kind of horizontal lacerable adhesive tape, it has the uncoated textile fabric carrier based on polyester or polymeric amide, wherein purposively destroy yarn (use alkaline purification PET, use the acid treatment polymeric amide) thus reduce fibre strength and therefore improve the tearable fragility of hand.With the anti-chemical of peeling off (Schiebefestchemikalien) thus further improve the tearable fragility of hand as the extra dipping of silicon ester.The alkalinization of PET-fabric for example can cause loss of strength big and raising gas and vapour permeability, and loss of strength is especially obvious to the negative impact of aging, thermal stresses, bending load and/or tension load.The advantageous effects that the raising of gas and vapour permeability brings when medical use is then brought disadvantageous effect when industrial application, infiltrate through in the gummous substance because oxygen, ozone and the gas that stimulates and liquid can have no the ground of obstruction, and this gummous substance is caused and is untreated or the Comparatively speaking bigger damage of fabric of coating well.
Though in industry, medical science and human consumer field, have a large amount of fabric adhesive tapes, but also do not know and be used for general-fabric adhesive tape that hand long-term outdoor application, high-quality tears.
Therefore, task of the present invention is to remove the defective of existing procucts, and develops a kind of
High-quality on vision and sense of touch,
Can simply make different colours,
The fabric adhesive tape that easy hand tears,
The base material (Untergrund) that it is common in multiple daily use can not lose that it is functional at least in six months even go up out of doors zone (Central Europe) life-time service yet.As measurement standard (Messlatte), the variation of this regulation respective measurement values is to the maximum 50%, on observed value such as maximum pull and the length direction tearing elongation and according to the bounding force of AFERA 5001 on steel.Also need to avoid visual considerable change as can be seen damage or crack, variable color or fade, the coming off of bonded substrate material.
This task is resolved by the adhesive tape described in independent claim.The theme of dependent claims is favourable further improvement of the present invention.
Therefore, the present invention relates to a kind of adhesive tape, this adhesive tape comprises that by the gram number be 50～150g/m 2The carrier made of 80～250 sieve mesh PET fabrics
Figure BPA00001276469800051
Being coated with coat weight on this carrier upside is 15～75g/m 2Plastic coating, be preferably water-and acrylate thickener (Acrylatpaste), and on this carrier downside, promptly with the opposite side that a plastic-faced side is provided on be coated with 70～200g/m 2UV stable from gummous substance, wherein the thickness that has of this adhesive tape is preferably at least 150 μ m.
Common expression " adhesive tape " comprises all two dimensional structures in the present invention, and the ribbon with tensile elongation and finite width, strap section (Bandabschnitt) and analogue as extending in two dimension also comprise Stanzlinge or label at last.
Have been found that, the resistance to atmospheric corrosion adhesive tape that can be used for high-quality Premium-Segment by following textile carrier accordingly: this textile carrier on the PET-fabric, be coated with sealing, colored plastic coating particularly, wherein raw fabric (Rohgewebe) has greater than 50g/m 2, 70～130g/m especially 2Weight per unit area, its backing coat be suitable UV stable from gummous substance.
Preferred minimum is that 150 μ m, the particularly thickness of 200～350 μ m have satisfied visual expectation.Be easy to the carrier that the tearable property of horizontal hand can the application of the invention and realize, and saved to use and cut out auxiliary means such as analogues such as cutter, cutting machine.Colored frosting setting makes adhesive tape seem high high-quality.
General-fabric the adhesive tape that is suitable for long-term outdoor application of the present invention is characterised in that following structure and preparation, and wherein explanation is exemplary and the technician can use and do not depart from the application's protection domain with modification.
For the reason of cost, as the carrier selection is that the gram number is 50～150g/m 2, 70～130g/m particularly 2Usually 80～250 sieve mesh fabrics of colouring not, this fabric since its special construction on laterally [also being called broadwise (Schussrichtung) or CD], have appropriateness at least with tearable fragility of hand and tear fracture (Ein-und Durchrei β barkeit).With colored water-and acrylate thickener or analogue with 15～75g/m 2, preferred 25～50g/m 2Coat weight apply a side of this carrier.
For fabric carrier especially advantageously, use two kinds of different prescriptions to apply colored coating successively with two-layer (in zwei Strichen).Major portion as coloured basal layer with 10～60g/m 2Directly be coated on the fabric.By using second-order transition temperature is that 0 ℃ and littler acrylic binder obtain softness and resilient coating, flexibility and feel (Griff) thereof that this coating can the favourable influence carrier, and can promote the fabric adhesive tape conformably bonding.On the colored coating of this partially enclosed sometimes (bonding under the pressurized), in the second layer, apply 5～20g/m 2Finish paint hard, that resistivity is arranged [topcoat].Not only improved tape surface thus to the resistivity of gummous substance itself (the direct contact between preparation, delivery period when depositing) with tape roll, and improved when using afterwards to might influence for example resistivity of mechanical stress, visible light, infrared ray or ultraviolet, water, chemical etc.This so-called finish paint is preferably selected from acrylate dispersoid, causes sclerosis comonomer for example vinylbenzene, methacrylic ester, vinyl cyanide polymerization reaction take place in this acrylate dispersoid.But the plastics film of other fast to light and chemicals-resistant for example vinyl acetate etc. also can be used as finish paint, and this plastics film is applied by dispersion or organosol and forms.
The carrier of the present invention that is made of the compound system of PET-fabric and preferred acrylate coatings not only has well the resistivity to various stress, as when it is used for outdoor application, showing, and carrier of the present invention has the operability of improving than raw fabric: being easy to tearable fragility and tear fracture does not in the horizontal need use to cut out instrument, and conjugate profile is carried out the adherent flexibility.Obtained high-grade fabric adhesive tape by this complex carrier.Thereby compare fabricbase adhesive tape and intermediate adhesive tape (Midgrades), fabric adhesive tape of the present invention has high-quality visual appearance.By (acrylate) plastic coating and the fabric by high sieve mesh fabric adhesive tape of the present invention is come with distinguishing with the fabricbase adhesive tape of PE-thin film coated and intermediate adhesive tape.
According to the present invention, as gummous substance to reverse side with 70～200g/m 2, 80～150g/m especially 2Apply UV resistant and moisture resistance from gummous substance, thereby firmly bonding on level and smooth, structurized and coarse base material when guaranteeing inner and outdoor application.At this, particularly advantageous as gummous substance is the acrylate gummous substance of modification and hydrogenant styrene-butadiene-styrene-block copolymer system (SBC) and styrene-isoprene-phenylethene-block copolymer system wholly or in part, particularly contains the prescription of partially hydrogenated styrene butadiene/butylene-styrene (SBBS) as the elastomerics composition.
Obtaining by product configurations of the present invention can be well and firmly be bonded in fabric adhesive tape on the different base material.
On steel as the standard adhesion base material of polar substrates, the bounding force of fresh state (preparation maximum weeks of back) reaches minimum 3.5N/cm, on polyethylene as non-polar substrate, the bounding force of fresh state (preparation maximum weeks of back) reaches 2N/cm at least, as requested, later maintenance reached 50% to this bounding force at least at 6 months.
Adhesive tape is peeled off and is not damaged carrier from most of common bonded substrate materials with noresidue ground or so that minimum is residual after using the most nearly 6 months.Therefore, compare when particularly the fabricbase adhesive tape is with intermediate adhesive tape with existing fabric adhesive tape, do not need to remove fragment or gummous substance residual (randomly can corrode the solvent of substrate surface), and existing fabric adhesive tape is as particularly fabricbase adhesive tape and intermediate adhesive tape can this thing happens and obvious can making troubles when using by meeting time-consumingly.
Of the present invention general-the fabric adhesive tape can be in the horizontal easily and with the steady tearing limit cuts off and can not produce wearing and tearing with hand.On the contrary, the fabric adhesive tape has high strength and therefore can be used for many application relevant with tensile strength on machine direction (Maschinenrichtung), as wrapping and fixing.Usually need high slightly initial force with torn edge, then can be easily and realize afterwards tear fracture equably.This is high slightly tears that strength is favourable has avoided taking place tear fracture unintentionally when handling fabric adhesive tape and final the application.
When the application of open air of the present invention general-the fabric adhesive tape is proved to be highly stable and is applicable at least 6 months prolonged application.When particularly the fabricbase adhesive tape resolved into its integral part after several weeks under the direct effect at sunlight and rainwater, fabric adhesive tape of the present invention kept following functional and product integrity:
● mechanical stress is had enough intensity,
● in substrate, adhere to fine,
● randomly, after use finishing substantially noresidue stripping tape once more.
Known natural rubber fabric adhesive tape and synthetic rubber fabric adhesive tape just do not possess last, this is after being attacked owing to two keys, the structural elasticity body is destroyed, and depend on prescription and load-bearing (Belastung Phase) mutually, gummous substance is from from soft and flowablely be changed to hard and exsiccant, and peels off once more with various opposings.
When using solid support material of the present invention, such adhesive tape has high-quality visual appearance.Replace open sparse crosslinked shape structure such as fabricbase adhesive tape, a kind of woven fabric structure of densification (as the clothing textiles) combines with high-quality frosting, this high-quality frosting obviously is different from the PE-film surface difference of " cheapness " of intermediate adhesive tape and fabricbase adhesive tape and comes, and the tearable property of high-tensile/hand that had positive combination unexpectedly and hand steady tearing (Handein-/und Weiterrei β barkeit) and the resistance to atmospheric corrosion that ultraviolet ray and sunlight also had humidity.
Each composition by suitable selection gummous substance can obtain the fine adhesive tape that adheres to of energy on different base materials with preparation, and this adhesive tape also can use out of doors the long period and performance can obviously not reduce.As gummous substance special and suitable be: polyacrylic ester and based on the system of the rubber of no unsaturated double-bond also has known rubber gummous substance with UV-stability of corresponding improvement.
Though have good machinery and tactile property, but do not recommend (modification) natural fiber such as cotton, viscose yarn (Viskose) or short rayon fiber element (Zellwolle) for open air application for a long time, because natural fiber also can be by microbiological degradation except the loss of strength under the humidity effect.The fiber of synthetic polymer is more favourable to this, and synthetic polymer for example has polyester (PET, PBT, PEN), polyacrylic ester, polymeric amide, polyimide, polyethylene, polypropylene etc.Provide PET as raw material especially, because PET is an erosion resistance, and have sufficient UV stable and humidity stability, and PET in worldwide textile field with the commercially available acquisition of form of fiber and circulation filament (Endlosfilament) and can supply at an easy rate.
From the beginning of the nineties, the PET-webbing just is applied to industrial circle such as cable is wrapped up, and what wherein mainly play a decisive role except non-corrosibility and higher lasting temperature stability and top temperature stability is high mechanical strength (for example for stretching and the high mechanical strength of friction).Yet PET-fabric adhesive tape is tesa for example
Figure BPA00001276469800081
51006 or 51026 is not to be that hand is lacerable, and must tear with cutter, scissors, divider (Dispenser) etc.Before 10 years, just introduced being labeled as the lacerable PET-fabric of hand adhesive tape, wherein by reducing weight per unit areas in a large number up to 70g/m 2Littler and by extra procedure of processing for example Chinzen (spreader calender) reduce intensity, yet this kind fabric be very thin and for the user this kind fabric especially film sample class rather than fabric, so this kind fabric is not suitable for high-quality general-fabric adhesive tape.Can not guarantee that this kind fabric is suitable for outdoor application.
Also having method steps can prepare the gram number by suitable selection yarn, woven fabric structure is 50～150g/m 2, be in particular 70～130g/m 2The PET fabric, its thickness is less than 100～250 μ m, and has the tearable fragility of gratifying hand and hand continues tearable fragility.Can on purpose fall yarn strength by the damage method of yarn of putting down in writing among DE 10 2,005 044 942 A1, thereby obtain through the ultimate tensile strength of upwards reservation and the equilibrium relationship between the horizontal tearable fragility.
Perhaps, fabric can be constructed like this: be chosen in the warp thread that must disconnect fully when laterally tearing in the fabric afterwards, make one warp do not need over-drastic strength just expend can: thereby tear with perhaps reducing silk thread cross section no problem, perhaps by selecting to regulate acceptable fracture behaviour through yarn material.In order to be implemented in the competent bulk strength on the warp-wise (MD=machine direction) in the fabric afterwards, select the number of threads on each unit of length, be to maximum 100N/cm from minimum 40N/cm with the MD maximum pull of realizing expectation.Ideal is general-and the MD maximum pull of fabric adhesive tape is 60～80N/cm.What be suitable as warp thread is the PET-yarn of 75den or littler fiber number (Titer) for example, also has hard brittle material, it is being torn with the impulse form intake time and is making warp break in the process: have suitable comonomer or crystalline PET-fiber, perhaps based on the warp thread of PA6.6.In order to make such warp have required sense of touch and visual appearance, must select corresponding thicker and heavier weft yarn.Realize that weight per unit area increases to 70g/m on the one hand thus 2Bigger, realize that on the other hand required fabric thickness reaches 100～250 μ m; Although warp thread is thinner, it is high-quality that this fabric still seems, this is because thicker parallel spins and determined visual appearance.From the PET-weft yarn of 150den is possible, but aspect visual appearance and sense of touch the PET-yarn of 300den especially advantageously.Similar establishment be to use other synthetic polymers to substitute the raw material of PET as yarn.
But preparing another possibility that has the substrate fabric of acceptable tearable fragility and breaking property on broadwise of the present invention is to use the yarn that is made of fibre blend as warp thread, and wherein at least a these fiber types are soluble and are removable afterwards therefore.Therefore, exist to have the enough yarns of intensity for spinning process and knitmesh process, and in follow-up method steps just tender realization make fabric have desired laterally can lancinating thinning and reduction.
Can consider multiple combination as fibre blend, wherein use polymkeric substance (for example PET-fiber) and the combination water-soluble or decomposition or zymolytic material (as polyvinyl alcohol, poly-lactic acid ester etc.) that resistivity is arranged as permanent warp thread.Depend on that selected fiber combinations selects mixture content like this, make the final strength of (warp) yarn in target zone.
Can apply other textile layer on fabric carrier, wherein all layers and fabric form by the line braiding of the trend that is parallel to each other especially.
Other textile layer can be made of fabric like the dry goods that uses with the present invention, but this textile layer can be made of other fabrics or non-woven fabrics.
Even use such uncoated textile single-coated foam, senior-general webbing also needs a high-quality single face plastic coating.Therefore realize level and smooth and uniform surface and seal this fabric, thereby keep harsh chemicals away from gummous substance and adhesive face.Realize on this coating in addition and give color flexibly that this is because more expensive to the painted price of fabric itself low-cost.Except these known aspects, beat all is that colored coating of the present invention obviously improves the tearable fragility of hand of the raw fabric of suitable prescription, thereby has reduced this relevant requirement to fabric itself.On the upside for the situation of single face coating that comprises suitable dyeing thickener under, this coating immerses in fabric the fabric thickness of half at least, it is by the decision of three-dimensional structureization surface.Dry and sclerosis back warp and parallel are fixed on geometrical dimension at plastic layer, and being similar among EP 1 074 595 A1 requirement must be by the fixing warp of adhesive coating.
Plastic coating can use multiple system in principle: the prepolymer system of organosol, radiation crosslinking, non-tackiness heat fusing thing, polymers soln etc.For the reason of existing standard paint-on technique in cost, availability and the textile field, preferably and what determine is aqueous dispersion.
For example can select polyurethane system, (ethene-) vinyl acetate system, PVC system, styrene butadiene system or acrylatcs systems as raw material.Reason and consideration " outdoor application/resistance to atmospheric corrosion " preferred acrylate for ecology, cost, availability.Depend on existing coating technology thickening (verdicken) acrylate and disperse acrylate, thereby prepare colored single face coating with corresponding coloured thickener/colored pigment.
Confirmed that particularly advantageous is two-layer-coating.In order to realize " feel " of good final fabric adhesive tape, promptly comfortable sense of touch, conformability and softish performance make this adhesive tape can be bonded in well on the arcual unfairness surface, and the basal layer of then giving color must be soft and have flexible.The second-order transition temperature of the tackiness agent in coloured thickener should be lower than room temperature, is in particular 0 ℃ or lower.
For the good resistivity of adhesive tape, hard chemical-resistant protective paint (Abschlusslack) is favourable.Layer below such finish paint has not only been protected, and selecting such finish paint can be used as the blocking layer of resisting gummous substance when correct, gummous substance after tape roll in directly contact with lining.Interacting, for example the integral part of tackiness agent migrates in the plastic coating or reverse migration is not expected, because this causes the change of each performance and be fuzzy in extreme case
Figure BPA00001276469800101
Clear interface between gummous substance and the frosting.The result is pull-up gummous substance and the therefore bigger uncoiling power of needs more with strength.Second-order transition temperature is higher than room temperature, particularly exceeds 30～50 ℃ and above finish paint, the particularly finish paint based on acrylate is suitable, what be fit to equally is with chemistry or the crosslinked system of hot mode, as long as final film performance is in identical scope.But finish paint can not be too hard, is carrying out slight crack can not occurring in the finish paint when bonding around the minor radius surface by bending or bending thus, and therefore can not damage the enamelled coating of sealing.
The plastic coating of giving color is with 15～75g/m 2, 20～50g/m particularly 2Whole adhesivity is used, with the layer and the uniform surface tissue of the good sealing of realization colouring.In the notion of two layers, basal layer has 50～95% main content.Below having confirmed for the reason of littler complicacy is favourable, uses pigmented layer as the basal layer of giving color with 70～95% total amount, and uses as the finish paint of covering enamelled coating colouring, transparent not with 5～30% total amount.It should be noted that aspect preparation and the method parameter, the sticking power of basal layer on raw fabric is high on the one hand, mixture sticking power between basal layer and finish paint also is high on the other hand, therefore can not cause breaking or coming off of coloured plastics layer in the adhesive tape afterwards, for example when making the film uncoiling.
By selecting suitable finish paint and gummous substance can not need the extra lacquerization (Release-lackierung) of peeling off.As required, when for example wishing adhesive tape uncoiling easily, can in finish paint, sneak into one or more and peel off additive (Releaseadditiv) or select a kind of independent lacquerization/peel off printing (Releaselackierung/-bedruckung) of peeling off.Because favourable and it has been determined that uncoiling power (peeling rate is 0.3m/min) is 2～8N/cm for can cosily operating, and can not use extra antiseized composition under normal conditions with hand.
A series of in principle gummous substance system can be used as adhesive coating.Except the adhesive property on the big as far as possible flat board of various base materials and adhesion property are good, each gummous substance must have sufficient stability to uv-radiation, light, oxygen, humidity etc., the requirement in the time of promptly must satisfying outdoor application.
Can use based on polysiloxane, the polyolefine system gummous substance of polyisobutene, pitch, urethane, polyvinyl acetate (PVA) and acrylate for example, but also use fixed natural and synthetic rubber gummous substance, particularly as long as eliminate the susceptibility of the two keys of elastomerics by corresponding light protective agent and protective agent.
Reason, preferred acrylate and stable natural and synthetic rubber system for the adhesive property of cost, availability and daily general adhesive tape.Because adhesive layer resists humidity, UV radiation etc. by solid support material, and have only the edge of sub-fraction, particularly adhesive tape directly under attack, so it is little as the requirement of the gummous substance of the adhesive tape of solid support material for example to have opening fabric or a ultraviolet ray-can see through film for the requirement of this gummous substance comparison.
The acrylate gummous substance itself is a uv radiation stability, can very well be bonded on the polar group bottom material, but defective then occurs when it is bonded on the nonpolar group bottom material.Can compensate described defective at least in part by in the pure acrylic acid ester, sneaking into appropriate resin or additive, wherein resin and additive can improve at the bottom of the nonpolar group as flow behavior on polyethylene or the polypropylene and adhesion behavior.Can apply the acrylate gummous substance as hot melt adhesive or as prepolymer or as dispersion by solution.Under the situation of dispersion, because the humidity contact during outdoor application notices that gummous substance has competent water tolerance.Dispersion early is owing to the reason of emulsifying agent can have very big moisture sensitivity, and modern acrylate dispersoid has obtained tangible improvement, and is applicable to such application.Notice that when using the crosslinked acrylate of radiation crosslinking, particularly UV degree of crosslinking keeps stable and remains unchanged basically when using out of doors.The further crosslinked bond properties that can change that influenced by solar irradiation for example reduces bounding force, thereby randomly can not use safely in long-time.
Yet what be mainly used in general-fabric adhesive tape is the rubber gummous substance, because the rubber gummous substance shows bounding force, viscosity and force of cohesion on nearly all dependency basis bottom material
Figure BPA00001276469800121
Good combination also have the equilibrated bond properties, therefore and this is fit to.Because the double key number order is bigger, but the elastomerics that is made of divinyl or isoprene unit is highstrung for the oxidation of ultraviolet ray, ozone etc. and thermal initiation.Structural polymer (Ger ü stpolymer) is understood under attack and is carried out partial cross-linked at two keys place, but also can decompose, this may greatly change bond properties: the honey shape flows or owing to the three-dimensional cross-linked lacquerization that causes (Verlackung), this represents completely losing of self-adhesion performance up to being to make the gummous substance deliquescing.General information about the rubber gummous substance can be with reference to the tool master book of adhesive tape such as " the Handbook of Pressure Sensitive Adhesive Technology " of Donatas Satas work.Even by uvioresistant additive such as carbon black, titanium dioxide, light protective agent for example HALS (hindered amine as light stabilizer) etc. can stablize significantly as existing general-the rubber gummous substance of the standard of fabric adhesive tape (fabricbase adhesive tape, intermediate adhesive tape, senior adhesive tape), but a large amount of two keys remain weakness in main chain, thereby such system is not first selection for senior adhesive tape.
More advantageously, hydrogenant or partially hydrogenated at least styrene butadiene-segmented copolymer (SBC) are as elastomerics composition (similarly, being fit to use styrene-isoprene-multipolymer).For example at review article " An Overview of Styrene Block Copolymer Adhesives " [Edward M.Petrie, Adhesives﹠amp; Sealants, www.specialchem4adhesives.com] in as can be known, can improve the permanent stability at thermooxidizing and photoxidation when using saturated SBC, saturated SBC has: styrene-ethylene-butadiene-styrene (SEBS) as hydrogenant SBS and styrene-ethylene-propylene-styrene (SEPS) as hydrogenant SIS.Hydrogenant elastomerics good stability in soft segment, but aspect adhesive property, change, and this can partly compensate by corresponding prescription.
For of the present invention senior general-the fabric adhesive tape for more advantageously partially hydrogenated elastomerics, it has good bond properties and has good outdoor anti-atmosphere simultaneously.Preparing based on vinyl aromatic compounds, optimization styrene and 1, during the block polymer of 3-diene (especially isoprene and divinyl), in diene block, not only generate 1, the diene of 2-addition (verkn ü pfen) and generate 1, the diene of 4-addition.1, the content of 2-diene can be controlled by the method operation.Because 1, the diene of 2-addition contains terminal double link, and 1, the double bond position in the diene of 4-addition in main chain, so can the selective hydration end and therefore have bigger reactive pair of key.
Put down in writing in DE 102 52 089 A1 based on the following gummous substance that is used for the adhesive foil bar, it can noresidue after distortion and has the ground of destruction and do not peel off once more.Beat allly be, by suitable filling a prescription based on this partially hydrogenated SBC-elastomerics, developed be used for general-fabric adhesive tape from gummous substance, should not only satisfy can be bonded in the requirement on the different base material more firmly but also having good long-time resistivity when using out of doors from gummous substance.
Gummous substance preferably includes following material:
● at least a segmented copolymer P1, it has one or more end-blocks and at least a blocks that is made of conjugated diolefine of being made of vinyl aromatic compounds (Vinylaromat), wherein greater than 80% pass through 1, the terminal double link that the 2-addition generates is through hydrogenant, and less than 30% pass through 1, the two keys of the main chain that the 4-addition generates are through hydrogenant, and
● at least a segmented copolymer P2, it has one or more by end-blocks and at least a block that is made of conjugated diolefine that vinyl aromatic compounds constitutes, and wherein two keys of at least 95% are through hydrogenant.
In an advantageous embodiment, this segmented copolymer has the polyvinyl aromatics content of 10 weight %～35 weight %.
In another advantageous embodiment, based on whole gummous substances, the total amount of two kinds of vinyl aromatic compounds segmented copolymers is 20～70 weight %, preferred 30～60 weight %, especially preferred 35～55 weight %.
Based on vinyl aromatic compounds, optimization styrene and 1, during the block polymer of 3-diene (especially isoprene and divinyl), in diene block, not only generate 1 in preparation, the diene of 2-addition and generate 1, the diene of 4-addition.1, the content of the diene of 2-addition can be regulated and control by solvent, temperature or catalyzer.Because 1, the diene of 2-addition contains terminal double link, and 1, the double bond position in the 4-addition diene in main chain, therefore optionally the hydrogenation end and therefore have more reactive pair of key.
Can use following polymkeric substance as segmented copolymer: a kind of have vinyl aromatic compounds such as a cinnamic block (A-block), another kind has by 1, the block (B-block) that the polymerization of 3-diene forms, 1,3-diene such as divinyl and isoprene or both mixtures.Thereby wherein the such polymerization of B-block make the B-block have greater than 20% high-loadly pass through 1,2-adds the vinyl that is shaped as, it is opposite with two keys in the main chain to be hydrogenant.If unhydrided segmented copolymer is SBS, then it generates so-called SBBS (styrene butadiene/butylene-styrene) behind selective hydration.Because the hydrogenant selectivity is not 100%, can use segmented copolymer, it is by 1, and the ethylene double bond that the 2-addition generates has that to surpass 80% be hydrogenant, and the two keys in the main chain only maximum 30% are hydrogenant.
Use following segmented copolymer as second composition: a kind of block (A-block) with vinyl aromatic compounds such as vinylbenzene formation, another kind has by 1, the block (B-block) that the polymerization of 3-diene forms, 1,3-diene such as divinyl and isoprene or both mixtures in all two keys of B-block are hydrogenant greater than 95% content wherein.
Segmented copolymer can have the A-B-A structure of straight chain.Can also use the segmented copolymer of radial structure and the segmented copolymer of star and straight chain.Can use the A-B Synthetic rubber, isoprene-styrene, hydrogenated, block, diblock as other compositions.
Alternative preferred polystyrene block also can use based on the homopolymer of other aromatic-containing compounds and multipolymer (preferred C 8-C 12Aromatic substance) polymer blocks, its second-order transition temperature are greater than about 75 ℃, for example contain the aromatic substance block of alpha-methyl styrene.
According to the present invention, two kinds of elastomericss, a kind of is that partially hydrogenated P1 and another kind are at least 95% hydrogenant P2, its ratio (weight quota) is 25: 75～90: 10, is preferably 40: 60～80: 20.
What use as tackifier (Klebrigmacher) is tackifying resin, and the elastomeric blocks of itself and vinyl aromatic compounds segmented copolymer is compatible.Suitable tackifying resin is preferably especially based on the unhydrogenation of rosin or rosin derivative, partially hydrogenated or complete hydrogenant resin, and the hydrogenation polymerisate of dicyclopentadiene is based on C 5-, C 5/ C 9-or C 9The unhydrogenation of-monomer flow, partially hydrogenated, selective hydration or complete hydrogenant hydrocarbon resin is based on the Polyterpenes resin of α-Pai Xi and/or beta-pinene and/or δ-limonenes.Above-mentioned tackifying resin can use or mix use separately.
Be the solid resin in the time of not only can using room temperature, be the resin of liquid in the time of also can using room temperature.
In order to ensure higher stability to aging and UV stable, preferred hydrogenant resin.
Usually use following material as other additives:
● softening agent, for example plasticizing oil or small molecules liquid polymer such as small molecules polybutene
● main Oxidation inhibitor, for example sterically hindered phenol
● auxiliary
Figure BPA00001276469800152
Oxidation inhibitor, for example phosphorous acid ester or thioether
● the process stabilizing agent is the C-radical scavenger for example
● anti-photic aging agent (Lichtschutzmittel), for example UV-absorption agent or bulky amine
● filler is fiber, carbon black, zinc oxide, titanium dioxide, little solid sphere (Mikrovollkugeln), glass solid sphere or glass hollow ball (Voll-oder Hohlglaskugeln), silicic acid, silicate, chalk for example
● the processing auxiliary material
● end-blocked enhancing resin, and
● choose other the polymkeric substance that preferably has elastomeric properties wantonly; Correspondingly spendable elastomerics, wherein particularly including elastomerics based on the pure carbon hydrogen compound, unsaturated polyester diene for example, as natural or synthetic polyisoprene that obtains or polyhutadiene, chemically saturated substantially elastomerics, for example saturated ethylene-propylene copolymer, alpha-olefin copolymer, polyisobutene, isoprene-isobutylene rubber, ethylene-propylene rubber, and the hydrocarbon polymer of chemical functionalization, for example halogen-containing, contain polyolefine acrylate or that contain vinyl ether, only listed a part seldom here.
Gummous substance of the present invention also can not comprise all described annexation.
The preparation of gummous substance and coating can be carried out with solution, dispersion and melts.Preferably operate with solution and with melts.Especially preferred is to use the melt preparation gummous substance, wherein uses batch processes and continuation method.Especially advantageously prepare continuously by extrusion machine.
Almost be independent of the type of employed gummous substance, of the present invention general-the fabric adhesive tape needs certain gummous substance thickness so that be bonded in rough securely or structurized base material as on wood, stone, the concrete etc.By 70～200g/m 2Coat weight realize required cementing property.After bonding technology effectively becomes absolute magnitude special also relevant with the structure of fabric: rough degree needs that depend on surface to be coated reach 50g/m most 2Coat weight, only in order to fill up the hole in the fabric, and the gummous substance of this part is stretched out " peak on fabric mountain range ", and adhesive effect is provided.For the gummous substance requirement of the required bond properties of roughly estimating of realization, the bed thickness of " effectively " is 60～150 μ m.
The selection of coating technology is relevant with the appearance form of gummous substance type and gummous substance.Here can use known system such as scraper, stitching, nozzle etc.The technician can carry out suitable selection without a doubt.Although in a lot of situations, the combination of gummous substance/coating technology can fully infiltrate in the hole of fabric and therefore gummous substance to cause adhesive layer to be fixed on the carrier well, yet when the gummous substance layer is for example extruded from nozzle and is used with form of film, the contact that must form powerful between two-layer and continue by extra applying pressure and temperature.This can for example realize by rolling press by follow-up pressure process and extrusion process.Perhaps, this also can for example realize that by extra prime coat (Primerstrich) this pre-treatment has strengthened gummous substance adhering on carrier in the physical/chemical mode by the carrier pre-treatment.As required, adhesive layer then carries out drying, crosslinked, sclerosis, and these are known systems for a long time.
Because belt performance of the present invention is very outstanding, it is particularly useful for outdoor application, for example in house and garden.If when adhesive tape is exposed in uv-radiation and the atmosphere, then show its profitability.This adhesive tape also seldom is subjected to the attack of nuisance.
Detection method
Bounding force
The following detection of carrying out bounding force.Use steel surface, polyethylene surface (PE) and 150 sieve mesh sand paper as the bonded substrate of determining.With manual cropping tool crop width is but that 20mm and length are the laminating flat element to be studied of about 25cm, and and then uses 4kg steel roller bearing to press five times on each selected bonded substrate with the speed (Vorschub) of 10m/min.And then required power is peeled off and measured to this cohesible surface element on the bonded substrate when room temperature with 180 ° angle with tension tester (Zwick company).Observed value (N/cm) is the mean value of three independent measurements.
The ultraviolet ray test
In order to measure that the UV stable sample that the wide and 25cm of 20mm is long is bonded on the sheet glass that thickness is 4mm and with 2kg roller rolling press five times.
Sample faced up with glass surface to be placed in the ultraviolet chamber with xenon lamp, and wherein yield of radiation is 300W/m 2Take out each new bar of each embodiment every day from ultraviolet chamber and regulate the back 1 hour room temperature and peel off from sheet glass.
Be recorded at this and whether exist considerable change, fragment (Rei β er) or gummous substance residual on sheet glass.
The resistance to atmospheric corrosion test
Substitute secular clean atmosphere corrosion (Freibewitterung), carry out so-called " Suntest " according to ISO 4892-2 (2006)., sample is bonded in firmly-PVC, on glass and the PE for this reason, and makes uviolizing and the instantaneous trickle that stands 765 watts of xenon lamps.In two hours circulation, after the combination of 18 minutes trickles and irradiation, carry out 102 minutes irradiation and do not carry out trickle.
In atomospheric corrosion after the stage, assessment visually readjusts the bar to the room temperature, then carries out 90 ° and 180 ° and peels off, and from fragment and residue angle it is assessed.According to the explanation (for example Atlas company) of manufacturers, the Suntester in a week is equivalent to the trimestral approximately clean atmosphere corrosion in Central Europe.
As long as the test bar of peeling off allows, the bounding force after mensuration is deposited.
In when southern angle of inclination is 45 °, on identical bonded substrate, realizing the persistence test that not timing is implemented down on the buildings balcony in hamburger in real outdoor condition (clean atmosphere corrosion).Test result and above-mentioned quick test result are suitable.
Below will further specify the present invention, and be not intended to restriction the present invention by some embodiment.
