[0002] Recovered Carbon Black (rCB)-filled elastomer materials in combination with comparable carbon black-filled materials
[0003] Field of the invention
[0004] The invention relates to components comprising an electrically conductive component made of an elastomer material containing industrial carbon black and a non-electrically conductive component made of an elastomer material containing recovered carbon black, wherein the two components are directly connected to one another via a contact surface.
[0005] State of the art
[0006] Conductive elastomer materials are used in a variety of fields. They are often used to prevent static charges, for example, in drive belts or refueling hoses. However, they are also often used in applications where they are only successful when combined with adjacent non-conductive components. Examples of this can mostly be found in the field of electronics and sensor technology, for example, in the form of film capacitors or in sensor applications. Sensor applications can include applications for temperature or load measurements, where the conductive elastomer material itself acts as the sensor material.
[0007] Industrial carbon blacks, especially standard carbon blacks, as they are currently used in technical elastomer materials, are conductive due to their graphitic layer structure and, at higher filler levels, almost always form the basis for electrical conductivity in elastomer materials.
[0008] Recovered carbon black (rCB) has been discussed for some time as a sustainable alternative material. These materials originate from the recycling of elastomer products and are manufactured using different processes than conventional carbon blacks or standard carbon blacks. Compared to carbon blacks, rCBs exhibit particularly altered surface properties due to the presence of numerous functional groups and amorphous carbonaceous residues. This is clearly noticeable in the conductivity properties, while the physical / mechanical reinforcement effects of rCBs are quite comparable to those of carbon black.
[0009] A disadvantage of the above-described prior art components, which combine electrically conductive elastomer materials with electrically non-conductive components, is that the contact surfaces, also known as the junction points, between the conductive and non-conductive materials are generally mechanically vulnerable. It is difficult to ensure that these materials have similar formulations and possess similar physical properties. This means that under mechanical stress, especially in highly dynamically stressed items, these junction points often become the starting point for component separation or failure.
[0010] Description of the invention
[0011] Against this background, there is a need for components that comprise an electrically conductive component made of an elastomer material in contact with an electrically non-conductive component that alleviates or eliminates the aforementioned disadvantages of the prior art. In particular, the object of the present invention was to provide such components that are characterized by low susceptibility to mechanical stress, especially dynamic stress.
[0012] Low susceptibility, in particular, means a strong connection between the electrically conductive component and the electrically non-conductive component, which is durable even under mechanical stress, so that defects at the contact surface or even detachment of the two components from each other, and thus component failure, can be minimized. Surprisingly, the inventors discovered that this problem can be solved by using an electrically non-conductive component made of an elastomer material containing recovered carbon black (rCB).
[0013] The invention thus relates to a component comprising an electrically conductive component made of an elastomer material comprising carbon black and an electrically non-conductive component made of an elastomer material comprising recovered carbon black (rCB), wherein the electrically conductive component and the electrically non-conductive component are directly connected to one another via a contact surface. As explained above, rCB, in contrast to conventional carbon blacks, is electrically non-conductive.
[0014] Investigations into the replacement of carbon black with rCBs in elastomer materials revealed that the mechanical and dynamic mechanical properties of the resulting components are very similar and, in many respects, even identical. Among the mechanical properties that may be similar or identical are, for example, hardness, elongation at break, tensile strength, and resilience.
[0015] Since rCBs may contain impurities due to the manufacturing process, they are generally dosed somewhat higher than carbon black (adjusted for the amount of impurities, e.g., approximately 5-10%). These impurities are not detrimental, but they also do not contribute positively to the mechanical properties.
[0016] Thus, it is possible to produce mechanically almost "identical" rCB-filled elastomer materials for carbon black-filled materials, which essentially only differ in their electrical properties, such as electrical conductivity and dielectric polarizability, thus providing a solution to the described technical problem.
[0017] According to the invention, components can be provided which comprise electrically conductive components in contact with electrically non-conductive components, wherein the mechanical properties of the electrically conductive component and the electrically non-conductive component can differ little or practically not at all.
[0018] Therefore, the components according to the invention are characterized by an excellent bond between the two components, offering optimal joint strength and durability, even under mechanical stress. This prevents the occurrence of defects or even detachment in components subject to high dynamic loads over a significantly longer period of time.
[0019] The invention enables the provision of components that comprise elastomer materials with homogeneous physical or mechanical material properties and simultaneously structured conductive and non-conductive areas.
[0020] Since the recycled product rCB is used in the components, the component is also more sustainable from an environmental point of view.
[0021] The invention is described in detail below.
[0022] Recovered carbon black (rCB), also known in Germany as tire pyrolysis black or pyrolysis black, is a type of recovered carbon black. The recycled product rCB is typically obtained from rubber waste, especially scrap tires, usually through pyrolysis processes and is commercially available. Standard terminology for recovered carbon black (rCB) can be found in ASTM D8178:2022, which is referenced here.
[0023] Commercially available rCBs generally contain production-related impurities that can amount to, for example, 2 to 25 wt.%, frequently 5 to 10 wt.%, of the total weight of the rCB. The impurities are not carbon black. Purified rCBs containing little or no impurities can also be used if necessary, but this is not preferred. The impurities are usually inorganic material, e.g., zinc compounds, silicon dioxide, and / or silicates. This contamination is due to additives contained in rubber waste, particularly scrap tires. The amount of contamination in an rCB can be easily determined analytically, e.g., by thermogravimetry. As stated above, the impurities have no adverse effects on the properties of the elastomer material.However, it should be noted that this level of impurity reduces the soot content in rCB, which is responsible for the effect, such as the reinforcement. Therefore, depending on the level of impurity, higher amounts of rCB must be used to replace industrial carbon black (fresh carbon black) with equivalent mechanical properties.
[0024] Recovered carbon black is obtained from a recovery process and differs from so-called renewable fillers or soot ("renewable carbon black"), which are obtained from bio-based, renewable raw materials such as wood.
[0025] Carbon black is a type of carbon black specifically manufactured as an industrial raw material, usually produced from fossil raw materials, particularly through incomplete combustion or pyrolysis of hydrocarbons ("fresh carbon black"). There are a variety of different types, each with specific properties. Internationally, the classification into "standard carbon blacks" is common according to the US ASTM standard. In ASTM D 1765, carbon blacks are divided into various types or standard carbon blacks based on their processing and vulcanization properties. The carbon black designations consist of a letter, S or N, a single-digit number, 1 to 9, followed by a two-digit number. The letter N stands for "normal" vulcanization kinetics. The first number indicates the particle size. A small number indicates a small particle diameter.
[0026] The component according to the invention comprises an electrically conductive component made of an elastomer material comprising carbon black. One or more carbon blacks may be present. The carbon black imparts electrical conductivity to the elastomer material or the component formed therefrom. Carbon black is used in the elastomer industry as a reinforcing filler. The use of carbon black has the advantage that it is generally resistant to aging and very compatible with elastomers and thermoplastic elastomers.
[0027] The carbon black in the electrically conductive component is preferably selected from the N500 series to N900 series according to ASTM, more preferably from the N500 series to N700 series according to ASTM, with ASTM types N550 and / or N772 being most preferred. These series according to ASTM refer to a group of carbon blacks that have the stated letter (N) and the stated first single-digit number (5, 6, 7, 8, or 9), where the following two-digit number can be any number assigned to a standard carbon black. For example, the N500 series according to ASTM includes all carbon blacks that begin with N5, e.g., N550.
[0028] Carbon blacks selected from the N500 series to N900 series according to ASTM and especially from the N500 series to N700 series are preferred because, compared to rCB, almost identical materials can be produced with regard to mechanical properties, which essentially only differ in the electrical properties (electrical conductivity, dielectric polarizability).
[0029] The rCB behaves particularly similarly to the standard carbon blacks of type N550 or N772, so that their replacement in an elastomer material is particularly well possible without significant changes in the mechanical properties.
[0030] The component according to the invention comprises an electrically non-conductive component made of an elastomer material comprising recovered carbon black (rCB). One or more types of rCB may be present. Recovered carbon black was described above, so reference is made thereto. As explained above, the rCB present cannot impart electrical conductivity to the elastomer material or the component formed therefrom. The elastomer material of the non-conductive component may optionally contain carbon black in addition to the recovered carbon black (rCB). The type and / or amount of carbon black that may optionally be present in the elastomer material of the non-conductive component must be selected such that no electrical conductivity is imparted to the elastomer material or the component formed therefrom.Preferred examples of additional carbon blacks are from the N500 to N900 series according to ASTM, particularly preferred are from the N500 to N700 series (due to their similar mechanical properties). The optional additional use of carbon black in the electrically non-conductive component containing rCB can, for example, allow the desired electrical and mechanical properties to be achieved.
[0031] The component made of an elastomer material containing carbon black is electrically conductive. The component made of an elastomer material containing rCB is electrically non-conductive.
[0032] An electrically conductive component made of an elastomer material is generally understood to be a component that has an electrical volume resistance of less than 10*10 3Q, measured according to DIN EN 62631-3-1:2017. An electrically non-conductive component made of an elastomer material is generally understood to be a component that has an electrical volume resistance of more than 10*10 9 Q, measured according to DIN EN 62631-3-1:2017.
[0033] The term electrical volume resistance is defined in DIN EN 62631-3-1. The unit for electrical volume resistance is the ohm. The electrical volume resistance, measured according to DIN EN 62631-3-1:2017, was determined on vulcanized elastomer materials with a thickness of 6 mm and a diameter of 60 mm. As suggested in DIN EN 62631-3-1, silver conductive ink was applied to the top and bottom of the samples as a contact material. For the conductive samples, the volume resistance between the top and bottom was then determined according to DIN EN 62631-3-1 at a measuring voltage of 6 V. For the non-conductive samples, the volume resistance between the top and bottom was determined according to DIN EN 62631-3-1 at a measuring voltage of 100 V.
[0034] In the component according to the invention, the electrically conductive component and the electrically non-conductive component are directly connected to each other via a contact surface. "Directly connected" means that the two components are directly connected to each other via the contact surface without any intermediate layers, such as adhesive layers.
[0035] Preferably, in the component according to the invention, the electrically conductive component and the electrically non-conductive component are directly connected to one another via a contact surface by vulcanization.
[0036] In a preferred embodiment, the amount of carbon black in the electrically conductive component is in the range of 20 to 50 wt.%, based on the total weight of the electrically conductive component.
[0037] The total carbon black in the electrically non-conductive component refers to the total amount of carbon black (rCB and industrial carbon black) in the electrically non-conductive component. In a preferred embodiment, the total amount of carbon black in the electrically non-conductive component is in the range from 20 to 50 wt.%, based on the total weight of the electrically non-conductive component, with at least 50 wt.%, preferably at least 80 wt.%, particularly preferably at least 95 wt.%, of the total carbon black being recovered carbon black (rCB). The proportion of impurities contained in the rCB is not taken into account for the amount of rCB contained in the component. If an rCB with a proportion of 10 wt.% impurities is used, for example, a quantity of 10 g of rCB used is counted as 9 g of rCB (the proportion of 1 g of impurities is not taken into account).It is preferred that the total amount of carbon black in the electrically non-conductive component is rCB.
[0038] Preferably, the elastomer material of the electrically conductive component and the elastomer material of the electrically non-conductive component are based on at least one elastomer and / or at least one thermoplastic elastomer. The elastomer material of the electrically conductive component and the elastomer material of the electrically non-conductive component are more preferably based on at least one elastomer. The at least one elastomer can be one elastomer or a mixture of two or more elastomers. The at least one thermoplastic elastomer can be one thermoplastic elastomer or a mixture of two or more thermoplastic elastomers.
[0039] Elastomer materials based on at least one elastomer are formed by vulcanizing a compound comprising one or more unvulcanized elastomers. The compound also typically contains vulcanizing agents, e.g., sulfur-based vulcanizing agents or peroxide vulcanizing agents, and one or more additives commonly used in rubber technology. The compound for the elastomer material for the electrically conductive component contains carbon black as described above. The compound for the elastomer material for the electrically non-conductive component contains rCB as described above.
[0040] Vulcanization can be carried out using any conventional vulcanization process. Vulcanization preferably takes place at a temperature in the range of 100 to 250°C, particularly preferably at a temperature in the range of 130 to 180°C. Vulcanization can be carried out, for example, at a pressure of 10 to 200 bar, optionally in an autoclave.
[0041] As already explained, the electrically conductive component and the electrically non-conductive component are preferably directly bonded to each other via a contact surface by vulcanization. For this purpose, an unvulcanized compound for the electrically conductive component and an unvulcanized compound for the electrically non-conductive component, each in the appropriate form, are brought into contact with each other and vulcanized together.
[0042] Elastomer materials based on at least one thermoplastic elastomer do not require vulcanization, as thermoplastic elastomers exhibit not only elastomeric properties but also thermoplastic properties. They can therefore be processed using conventional thermoplastic processes, such as extrusion.
[0043] Elastomer materials based on at least one thermoplastic elastomer are formed from a compound comprising one or more thermoplastic elastomers. The compound may contain one or more conventional additives. The compound for the elastomer material for the electrically conductive component contains carbon black as described above. The compound for the elastomer material for the electrically non-conductive component contains rCB as described above.
[0044] An electrically conductive component and an electrically non-conductive component, each based on an elastomer material based on at least one thermoplastic elastomer, can be directly joined together, for example by coextrusion.
[0045] The at least one elastomer for the electrically conductive component and the at least one elastomer for the electrically non-conductive component can, for example, be independently selected from the group consisting of acrylonitrile-butadiene rubber (NBR), carboxyl group-containing nitrile rubber (XNBR), ethylene-vinyl acetate copolymer (EVAC), ethylene-vinyl acetate rubber (EVM), hydrogenated acrylonitrile-butadiene rubber (HNBR), perfluoro rubber (FFKM), ethylene-acrylate rubber (AEM), polyacrylate rubber (ACM), chloropolyethylene rubber (CM), chlorosulphonyl polyethylene rubber (CSM), ethylene-propylene-diene rubber (EPDM), ethylene-propylene rubber (EPM), fluororubber (FKM), Epichlorohydrin rubber (CO), epichlorohydrin copolymer rubber (ECO), epichlorohydrin terpolymer (GECO), polydimethylsiloxane (PDMS), propylene oxide copolymer rubber (GPO), butadiene rubber (BR), chloroprene rubber (CR), isobutene-isoprene rubber (HR), bromobutyl rubber (BIIR),Chlorobutyl rubber (CIIR), isoprene rubber (IR), natural rubber (NR), styrene-butadiene rubber (SBR), fluorosilicone rubber (FVMQ), methylphenylsilicone rubber (PMQ), methylphenylvinylsilicone rubber (PVMQ), methylsilicone rubber (MQ), methylvinylsilicone rubber (VMQ), polyester urethanes (AU), polyether urethanes (EU) and combinations thereof.
[0046] The thermoplastic elastomer for the electrically conductive component and the thermoplastic elastomer for the electrically non-conductive component can, for example, be independently selected from the group consisting of thermoplastic vulcanizate (TPV), thermoplastic polyolefin (TPO), thermoplastic polyurethane (TPU) and combinations thereof.
[0047] The elastomer material for the electrically conductive component and the elastomer material for the electrically non-conductive component may independently contain one or more further additives that are conventional in the art. Examples of such additives include plasticizers, additional fillers other than carbon black, such as silica or calcium carbonate, processing aids, anti-aging agents, or combinations thereof. In general, it is preferred that the elastomer material for the electrically conductive component and the elastomer material for the electrically non-conductive component do not contain any fillers other than carbon black.
[0048] A particular advantage of the components according to the invention is that the electrically conductive component and the electrically non-conductive component can be manufactured from elastomer materials that differ only in the type and, if applicable, amount of carbon black used. Thus, the same formulation can be used for the base compound for both components, which is then mixed with the respective type and amount of carbon black to obtain the elastomer materials for the electrically conductive component and the electrically non-conductive component. This simplifies the manufacturing process and, at the same time, the components exhibit virtually identical mechanical properties, which can significantly improve the bond strength and durability of the components.
[0049] In a preferred embodiment, the elastomer material of the electrically conductive component and the elastomer material of the electrically non-conductive component comprise the same at least one elastomer and / or thermoplastic elastomer.
[0050] In a preferred embodiment, the component according to the invention is intended for electrical contacting. This is achieved, for example, by bringing a metallic contact element such as a terminal, an electrode, or a strength member into contact with the electrically conductive component. This contacting can be further assisted by a defined contact moment. Therefore, depending on the intended application, the points on the surface of the electrically conductive component intended for contacting must be selected. These points can be selected by a person skilled in the art in a suitable manner.
[0051] Therefore, in a preferred embodiment, the electrically conductive component in the component according to the invention is provided with electrical contact points.
[0052] The component according to the invention is suitable for components of any design and complexity. The electrically conductive component can function, for example, as an electrical conductor or electrode. The electrically non-conductive component can function, for example, as an insulator. Neither the shape nor the number of electrically conductive components and electrically non-conductive components are limited in the component according to the invention.
[0053] The component according to the invention can, for example, comprise more than one electrically conductive component made of an elastomer material comprising carbon black as described above and / or more than one electrically non-conductive component made of an elastomer material comprising rCB as described above, which are preferably arranged alternately.
[0054] The component according to the invention can preferably be an electronic component, an EMC shielding material, or a non-visible marking, preferably a security marking. Preferred examples of an electronic component are a capacitor, preferably an elastic capacitor, a sensor component, or an electrical switching element. The capacitor, in particular the elastic capacitor, is preferably a film capacitor.
[0055] EMC stands for electromagnetic compatibility and describes the ability of an EMC shielding material to protect devices or equipment from unwanted electrical or electromagnetic effects.
[0056] An invisible marking, preferably a security marking, by the component according to the invention can be achieved, for example, by a patterned arrangement of the electrically conductive component and / or the electrically non-conductive component. If the components are formed with the same color, they are visually indistinguishable from one another, especially if one or both components are formed with a small thickness. However, a marking formed by the pattern can be read by measuring the different electrical conductivity.
[0057] The shape and dimensions of the two components can be largely freely selected. In one embodiment of the component according to the invention, for example, the electrically conductive component can be cord-like and encased by the electrically non-conductive component. In this way, the component can have a cable-like configuration. In this embodiment, the component according to the invention can be used, for example, as an electrical cable. The electrically conductive component can have, for example, a circular, oval, or rectangular cross-section.
[0058] It is also possible for one or both components of the component according to the invention to be arranged in a pattern. In this case, it is particularly advantageous if the respective components are visually indistinguishable from one another. Since the components differ in their electrical properties, hidden or invisible information can be read out using appropriate measuring instruments that can determine differences in electrical conductivity.
[0059] In a further preferred embodiment of the component according to the invention, one component, preferably the electrically non-conductive component, forms a surface on which the other component, preferably the electrically conductive component, is arranged in a pattern, wherein the pattern is preferably not visually visible. This can be achieved by having both components of the same color, particularly if the patterned component has a small thickness. The pattern can represent, for example, words, numbers, symbols, barcodes, and / or a security marking. The information can then be read using appropriate measuring instruments or sensors.
[0060] In a further preferred embodiment of the component according to the invention, the electrically conductive component and the electrically non-conductive component are each formed in the form of layers. The component according to the invention can also comprise more than one electrically conductive component and / or more than one electrically non-conductive component. In this way, multi-layer components can be produced, which can be used, for example, as elastic capacitors or layer capacitors.
[0061] In a preferred embodiment, the component according to the invention therefore comprises more than one electrically conductive component and / or more than one electrically non-conductive component, each of which is formed in the form of layers, wherein the electrically conductive and electrically non-conductive components are preferably arranged alternately.
[0062] A component according to the invention can, for example, be in the form of a layered capacitor. Two electrically conductive components in the form of layers form the electrodes, between which an electrically non-conductive component in layered form is arranged as a dielectric and is directly connected to the two electrically conductive components. The electrically conductive components are each provided with electrical contact points via which the layered capacitor can be connected to an electrical circuit.
[0063] The present invention also relates to the use of the component according to the invention as described above as an electronic component, EMC shielding material, or invisible marking, preferably a security marking. The electronic component is preferably a capacitor, preferably an elastic capacitor, a sensor component, or an electrical switching element. The capacitor, in particular the elastic capacitor, is preferably a film capacitor.
