Description

Field of the InventionThe invention relates to components which comprise an electrically conductive component made of an elastomer material containing carbon black and a non-electrically conductive component made of a recovered elastomer material containing carbon black, wherein the two components are directly connected to one another via a contact surface.Prior ArtConductive elastomer materials are used in various fields. They are often used to prevent static charges, for example in drive belts or filling hoses. However, they are often also used in applications in which they are only successful by combination with adjacent non-conductive components; examples of this are usually found in the field of electronics and sensor systems, for example in the form of layered capacitors or in sensor system applications. Sensor applications can be, for example, applications for temperature or load measurements in which the conductive elastomer material itself functions as sensor material.Carbon blacks, in particular standard carbon blacks, as are used as standard today in industrial elastomer materials, are conductive because of their graphitic layer structure and almost always form the basis for electrical conductivity in elastomer materials at higher filling levels.As lasting alternative materials, "recovered carbon black" (rCB), among others, has been discussed for some time. These are due to recycling processes of elastomer articles and are produced by processes other than the customary carbon blacks or standard carbon blacks. In comparison with carbon blacks, rPTFEs have in particular altered surface properties due to the presence of many functional groups and amorphous carbonaceous residues. This is clearly noticeable in the conductivity properties, while the physical / mechanical amplification effects of rCBs are quite comparable to those of carbon black.A disadvantage of the above-described components according to the prior art, in which electrically conductive elastomer materials are used in combination with electrically non-conductive components, is that the contact surfaces, also referred to as assembly points, of the conductive and non-conductive materials are generally mechanically vulnerable. It is difficult to realize that these materials have similar formulations and have similar physical properties. This means that in the case of mechanical loads, in particular in the case of articles subjected to high dynamic loads, these connection points often become the starting point for the separation or the failure of the component.DESCRIPTION OF THE INVENTIONAgainst this background, there is a need for components which have an electrically conductive component made of an elastomer material in contact with an electrically non-conductive component, which mitigate or eliminate the aforementioned disadvantages of the prior art. In particular, the object of the present invention was to provide such components which are distinguished by low susceptibility to mechanical loading, in particular dynamic loading.A low susceptibility here means in particular a strong connection between the electrically conductive component and the electrically non-conductive component, which is durable even under mechanical load, so that flaws on the contact surface or even detachment of the two components from one another and thus failure of the component can be minimized.Surprisingly, the inventors have found that the object can be achieved by using an electrically non-conductive component made of a recovered elastomer material containing carbon black (r).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 is not electrically conductive, unlike the conventional carbon blacks.The studies on the replacement of carbon blacks by rPTFEs in elastomeric materials revealed that the mechanical and dynamic mechanical properties of the components formed therefrom are very similar and in many respects even identical. Mechanical properties which may be similar or identical include, for example, hardness, elongation at break, tensile strength or rebound elasticity.Since rCBs can contain impurities on account of the production process, they are generally metered somewhat higher in comparison with carbon black (adjusted to the amount of impurity, for example about 5-10%). The impurities do not interfere, but also do not contribute positively to the mechanical properties.It is thus possible to produce virtually "identical" rPTFE-filled elastomer materials mechanically for materials filled with carbon black, which substantially differ only in the electrical properties, such as electrical conductivity, dielectric polarizability, and thus provide a solution for the described technical problem.According to the invention, it is possible to provide components which comprise electrically conductive components in contact with electrically non-conductive components, wherein the mechanical properties of the electrically conductive component and of the electrically non-conductive component can differ little or virtually not at all.Therefore, the components according to the invention are distinguished by an excellent connection of the two components with an optimum connection strength and durability, even under mechanical stress. Thus, in the case of components with a high dynamic load, the occurrence of defects or even detachments over a significantly extended period of time can be avoided.The invention enables the provision of components which comprise elastomer materials with homogeneous physical or mechanical material properties and simultaneously structured conductive and non-conductive regions.Since the recycled product rCB is used in the components, the component is additionally more durable from an environmental point of view.The invention will be described in detail below.Recovered carbon black (rCB), which is also referred to in Germany as tire pyrolysis black or pyrolysis black, is a recovered carbon black. The recycled product rCB is generally obtained from waste rubbers, in particular used tires, usually by pyrolysis processes and is commercially available. A standard terminology relating to recovered carbon black (rCB) is found in ASTM D8178:2022, to which reference is made.Commercial rs generally contain impurities, which are due to the production and which may make up, for example, 2 to 25% by weight, frequently 5 to 10% by weight, of the total weight of the rCB. The impurities are not carbon black. Purified rDNA containing little or no impurity may also be used if desired, but this is not preferred. The impurities are usually inorganic material, for example zinc compounds, silicon dioxide and / or silicates. This contamination is attributed to additives contained in the rubber waste, in particular used tires. The amount of impurity in an rDNA can be readily determined analytically, e.g., by thermogravimetry.As stated above, the contaminants do not adversely affect the properties of the elastomeric material. However, it is considered that this amount of impurity reduces the amount of soot in rCB, which is responsible for the effect such as the strengthening effect. Corresponding to the amount of impurity, therefore, higher amounts of rCB must be used in order to equivalently replace an carbon black (fresh carbon black) in terms of mechanical properties.Recovered carbon black is obtained from a recovery process and is different from so-called renewable fillers or carbon blacks ("renewable carbon black") which are obtained from bio-based renewable raw materials, such as wood.Carbon black is a carbon black specifically produced as an industrial base material, which is generally produced from fossil raw materials, in particular by incomplete combustion or pyrolysis of hydrocarbons ("fresh carbon black"). There are a variety of different types, each with specific properties. Internationally customary is classification in "standard carbon blacks" according to the U.S. ASTM standard. In ASTM D 1765, the carbon blacks are divided into various types of carbon blacks or standard blacks by processing and vulcanization properties. The carbon blacks are characterized as comprising a letter, S or N, a single digit number, 1 to 9, followed by a two digit number. The letter N represents "normal" vulcanization kinetics. The first number indicates the particle size. A small number means a small particle diameter.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 included. The carbon black contained therein gives the elastomer material or the component formed therefrom the electrical conductivity.Carbon black is used in the elastomer industry as a reinforcing filler. The use of carbon black has the advantage that it is basically resistant to ageing and is very well compatible with elastomers and thermoplastic elastomers.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. This series according to ASTM refers to a group of carbon blacks having the said letter (N) and the said first single digit number (5, 6, 7, 8 or 9), wherein the following two digit number may be any number assigned to a standard carbon black. For example, the N500 series according to ASTM includes all carbon blacks beginning with N5, e.g., N550.Carbon blacks selected from the N500 series to N900 series according to ASTM and in particular from the N500 series to N700 series are preferred, since nearly identical materials can be produced with regard to the mechanical properties, which materials differ substantially only in the electrical properties (electrical conductivity, dielectric polarizability) in comparison with rCB.The rCBs behave particularly similarly to the standard carbon blacks of the type N550 or N772, so that here the exchange in an elastomer material is possible particularly well without substantial changes in the mechanical properties.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 rCB types may be included. Recovered carbon black has been described above, as referred to. As stated above, the rPTFE contained therein cannot impart electrical conductivity to the elastomer material or to the component formed therefrom.The elastomer material of the non-conductive component may optionally additionally contain carbon black in addition to the recovered carbon black (rCB). The type and / or amount of carbon black, which may optionally be contained in the elastomer material of the non-conductive contained component, is to be selected such that no electrical conductivity is imparted to the elastomer material or the component formed therefrom. Preferred examples of carbon blacks which can additionally be used are from the N500 series to N900 series according to ASTM, particularly preferably from the N500 series to N700 series (on account of the similar mechanical properties). By optionally additionally using carbon black in the electrically non-conductive component containing rCB, desired electrical and mechanical properties can be set, for example.The component made of an elastomer material containing carbon black is electrically conductive. The component made of an elastomer material containing rCB is not electrically conductive.An electrically conductive component made of an elastomer material is generally understood to mean a component which has an electrical contact resistance of less than 10*10 3 Ω, measured according to DIN EN 62631-3-1:2017. An electrically non-conductive component made of an elastomer material is generally understood to mean a component which has an electrical contact resistance of more than 10*10 9 Ω, measured according to DIN EN 62631-3-1:2017.The term electrical contact resistance is defined in DIN EN 62631-3-1. Ohms is defined as a unit for the electrical contact resistance. The electrical contact resistance measured according to DIN EN 62631-3-1:2017 was determined here on vulcanized elastomer materials having a thickness of 6 mm and a diameter of 60 mm. As proposed in DIN EN 62631-3-1, silver conductive lacquer was applied as contact material to the upper and lower sides of the samples. For the conductive samples, the resistivity between the top and bottom sides was then determined in accordance with DIN EN 62631-3-1 at a 6 V measurement voltage. For the non-conductive samples, the resistivity between the top and bottom was determined in accordance with DIN EN 62631-3-1 at a 100 V measurement voltage.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. Directly connected to one another means that the two components are connected to one another via the contact surface directly without intermediate layers, such as adhesive layers, for example.In the component according to the invention, the electrically conductive component and the electrically non-conductive component are preferably directly connected to one another via a contact surface by vulcanization.In a preferred embodiment, the amount of carbon black in the electrically conductive component is in the range from 20 to 50% by weight, based on the total weight of the electrically conductive component.The total carbon black in the electrically non-conductive component refers to the total amount of carbon black (rCB and carbon black) in the electrically non-conductive component. In a preferred embodiment, the amount of carbon black overall in the electrically non-conductive component is in the range from 20 to 50% by weight, based on the total weight of the electrically non-conductive component, wherein at least 50% by weight, preferably at least 80% by weight, particularly preferably at least 95% by weight, of the carbon black overall is recovered carbon black (rCB). For the amount of rCB contained in the component, the fraction of impurity contained in the rCB is not taken into account. When an r containing 10 wt% impurity is used, for example, an amount of 10 g of the rCB used is evaluated as 9 g of rCB (the amount of 1 g impurity is not considered).It is preferred that the total amount of carbon black in the electrically non-conductive component is rCB.The elastomer material of the electrically conductive component and the elastomer material of the electrically non-conductive component are preferably 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 may be an elastomer or a mixture of two or more elastomers. The at least one thermoplastic elastomer may be a thermoplastic elastomer or a mixture of two or more thermoplastic elastomers.Elastomer materials based on at least one elastomer are formed by vulcanization of 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 common in the field of rubber technology. In the compound for the elastomer material for the electrically conductive component, carbon black is contained as described above. In the compound for the elastomer material for the electrically non-conductive component, rCB is contained as described above.Vulcanization may be carried out by any conventional vulcanization method. Vulcanization is preferably carried out at a temperature in the range from 100 to 250° C., particularly preferably at a temperature in the range from 130 to 180° C. Vulcanization can be carried out, for example, at a pressure of 10 to 200 bar, optionally in an autoclave.As already stated, the electrically conductive component and the electrically non-conductive component are preferably directly connected to one another via a contact surface by vulcanization. For this purpose, an unvulcanized compound for the electrically conductive component and an unvulcanized compound for the electrically nonconductive component, which are present in the respective form provided for this purpose, are brought into contact with one another and vulcanized together.Elastomer materials based on at least one thermoplastic elastomer do not require vulcanization, since thermoplastic elastomers have not only elastomeric properties but also thermoplastic properties. They can therefore be processed by conventional thermoplastic processes, for example by extrusion.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. In the compound for the elastomer material for the electrically conductive component, carbon black is contained as described above. In the compound for the elastomer material for the electrically non-conductive component, rCB is contained as described above.An electrically conductive component and an electrically non-conductive component, each of which is based on an elastomer material based on at least one thermoplastic elastomer, can be directly connected to one another, for example, by coextrusion.The at least one elastomer for the electrically conductive component and the at least one elastomer for the electrically non-conductive component can be selected, for example, independently of one another 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), fluoro rubber (FKM), epichlorohydrin rubber (CO), epichlorohydrin copolymer rubber (ECO), epichlorohydrin terpolymer (GEO), polydimethylsiloxane (PDMS), propylene oxide copolymer rubber (GPO), butadiene rubber (BR), chloroprene rubber (CR), isobutene-isoprene rubber (IIR), bromobutyl rubber (BIIR), chlorobutyl rubber (CIIR), isoprene rubber (IR), natural rubber (NR), styrene-butadiene rubber (SBR), fluoro-silicone rubber (FVMQ), Methyl phenyl silicone rubber (PMQ), methyl phenyl vinyl silicone rubber (PVMQ), methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ), polyester urethanes (AU), polyether urethanes (EU), and combinations thereof.The thermoplastic elastomer for the electrically conductive component and the thermoplastic elastomer for the electrically non-conductive component may, for example, be independently selected from the group consisting of thermoplastic vulcanisate (TPV), thermoplastic polyolefin (TPO), thermoplastic polyurethane (TPU), and combinations thereof.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 common in the art. Examples of such additives are 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 preferable that fillers other than carbon black are not contained in the elastomer material for the electrically conductive component and the elastomer material for the electrically non-conductive component.A particular advantage of the components according to the invention is that the electrically conductive component and the electrically non-conductive component can be produced from elastomer materials which differ only in the type and optionally amount of the carbon black used. It is therefore possible to use the same formulation for the base compound for both components, which is then admixed with the respective type and amount of carbon black in order to obtain the elastomer materials for the electrically conductive component and the electrically non-conductive component. This results in a simplification of the production process and at the same time the components exhibit virtually identical mechanical properties, as a result of which the bond strength and durability of the bond of the components can be significantly improved.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.The component according to the invention is provided for electrical contacting in a preferred embodiment.

Depending on the intended application, the points on the surface of the electrically conductive component that are intended for contacting are therefore to be selected.

In this way, the component can have a cable-like shape. In this embodiment, the component according to the invention can be used, for example, as an electrical line.
