Definitions
- the present invention relates to a conveyor belt as defined in the preamble of independent patent claim 1.
- Known conveyor belts consist, for example, of one or more flat textile products which are coated on one side or on both sides with at least one thermoplastic.
- the textile products often comprise fibers made of polyethylene terephthalate, polyamide 6, polyamide 66 or aromatic polyamides.
- the plastics used for coating are mostly soft PVC mixtures, thermoplastic polyurethanes, partially crosslinked polyolefin / elastomer mixtures, polyolefin homopolymers, polyether block amide copolymers or styrene block copolymers. Due to the intimate connection of the coating materials with the textile products, conveyor belts cannot be broken down into single-grade plastics again.
- a conveyor belt has to be created that can be recycled in terms of raw materials without having to separate it into individual components.
- Conveyor belt that contains at least one flat textile product that is coated on at least one side with at least one thermoplastic, both the at least one textile product and the at least one thermoplastic coating plastic, each with at least 90 percent by volume of at least one thermoplastic polyolefin hoopolymer , thermoplastic polyolefin copolymer, a thermoplastic polyolefin / elastomer mixture or a mixture thereof.
- the elastomers can be cross-linked, partially cross-linked or non-cross-linked.
- both the at least one textile product and the at least one thermoplastic coating plastic consist largely of thermoplastic polyolefins, such a conveyor belt can be melted into a relatively homogeneous melt at the end of its service life. This melt can then be used as a full plastic raw material.
- the conveyor belt preferably consists only of at least one flat textile product and at least one thermoplastic coating plastic, each consisting of at least 90 percent by volume of at least one thermoplastic polyolefin homopolymer, thermoplastic polyolefin copolymer, a thermoplastic polyolefin / elastomer mixture or a mixture thereof , Because the conveyor belt only consists of one or more textile products and one or more coating plastics in the defined compositions and has no other components, it is easy to melt into a very homogeneous melt without having to remove components beforehand.
- the melting point of the at least one textile product, determined by means of dynamic differential calorimetry, is advantageously higher by at least 15 K, in particular by at least 25 K, than the melting point of the at least one thermoplastic coating plastic, determined by means of dynamic differential calorimetry. This enables one
- the at least one flat textile product and the at least one thermoplastic coating plastic each consist of at least 90 percent by volume of polyethylene homopolymer, polyethylene copolymer or a mixture thereof.
- Possible polyethylene copolymers are poly (ethylene-co-vinyl acetate), poly (ethylene-co-methyl acrylate), poly (ethylene-co-ethyl acrylate), poly (ethylene-co-butyl acrylate), poly (ethylene-co-acrylic acid) ), Poly (ethylene-co-n-pentene), poly (ethylene-co-n-pentene) hexene), poly (ethylene-co-n-octene), poly (ethylene-co-styrene).
- the proportion of comonomers can be 0-40 mole percent.
- the polymers can in particular also be synthesized using metallocene catalysts.
- the at least one flat textile product and the at least one thermoplastic coating plastic each consist of at least 90 percent by volume of polypropylene homopolymer, polypropylene copolymer, a thermoplastic polyolefin / elastomer mixture based on polypropylene or a mixture thereof.
- Possible polypropylene copolymers are ethylene / propylene-diene copolymers and copolymers of propylene with the co onomers ethylene, butene-1 and / or higher ⁇ -olefins.
- the proportion of comonomers can be 0 to 40 mole percent each.
- thermoplastic polyolefin / elastomer mixtures or polyolefin elastomers are, for example, mixtures of polypropylene with any proportion of crosslinked, partially crosslinked or uncrosslinked ethylene / propylene-diene copolymers.
- the polymers can in particular also be synthesized using metallocene catalysts.
- the polyolefin / elastomer mixture advantageously contains additives, in particular oils as plasticizers. These additives are part of the above 90 percent by volume.
- the at least one textile product is preferably a woven fabric. This enables high tensile strength to be achieved in both the longitudinal and transverse directions.
- the at least one textile product contains fibers or filaments which conduct electrical current, in particular fibers or filaments made of metal, metal-coated or carbon-coated fibers or carbon fibers. These conductive fibers or filaments can be used to dissipate electrostatic voltages.
- the at least one textile product has different bending stiffnesses in the longitudinal and transverse directions.
- Conveyor belts according to the invention can be used to transport a wide variety of goods.
- the transport of food is also possible with a suitable choice of material.
- a conveyor belt according to the invention can be produced using a large number of processes which belong to the prior art.
- the at least one textile product can be coated with the coating plastic by means of extrusion coating, by means of melt coating with a calender, by laminating on a previously produced film or web or by means of powder coating.
- a flat textile product can be coated on both sides with plastic.
- a conveyor belt can include several textile products, which are arranged in parallel layers.
- conveyor belts according to the invention can be separated into individual loads without prior separation. Process components in an extruder or kneader to a homogeneous plastic mixture.
- the plastic mixture obtained in this way can be used as a raw material for producing any suitable products such as, for example, conveyor belts, plastic webs, foils, pipes or injection molded articles. Conveyor belts according to the invention can thus be recycled in terms of raw materials.
- a commercial fabric with a plain weave which has a basis weight of 130 g / m 2 and consists of fibers made of ultra-high molecular weight polyethylene (brand name Dyneema ® , manufacturer DSM), was coated on both sides by means of an extrusion coating with a coating of polyethylene with a density of 0.902 g / cm 3 and a melting point of 99 ° C. determined by means of dynamic differential calorimetry.
- the temperature of the polyethylene in the extruder head was 173 ° C.
- the conveyor belt thus obtained had the following properties:
- Thickness 1.30 mm
- the tape thus produced was mechanically crushed. Then it was melted and homogenized in a commercial kneader with roller rotors at a chamber temperature of 180 ° C. A melt temperature of 200 ° C was established.
- the plastic mixture obtained in this way was pressed in a heating press to form a plate 0.5 mm thick.
- the plastic mixture plate had the following properties:
