Definitions

  • the invention relates to a belt material for conveyor and conveyor belts, which consists essentially of a nonwoven, binder and a reinforcement.
  • a low-stretch conveyor belt is already known, the low elongation of which is achieved by means of parallel textile yarns as reinforcements, which have a maximum elongation of 20% at 50% of the nominal breaking load.
  • the substantially parallel textile yarns are connected to at least one layer of staple fibers by needling.
  • the parallel textile yarns as well as the layer of staple fibers are enclosed by a matrix made of a cell-free elastomeric polymer resin.
  • the fiber mixture for needle punch nonwovens can consist of synthetic fibers such as polyamide, polyester, polyolefin, acrylic fibers and / or natural fibers such as jute.
  • the staple fiber sheet can be needled onto the textile yarns on one or both sides.
  • the textile yarns used as reinforcements can be polyester or polyamide yarns.
  • the needle nonwoven is impregnated with a liquid intermediate product which, after drying and vulcanization, provides a cell-free polymer resin.
  • a nitrile-butadiene-rubber dispersion is preferably used for this.
  • Conveyor belts made of such a material have a low-noise running and a high cut resistance compared to conventional belts coated with fabric, but still have only a limited usability because the yarns or fabrics used as reinforcement have inherent tensions caused by the Enhance the needling process. As a result, short and wide bands in particular can no longer be controlled, i.e. the belt runs after a few turns.
  • the object of the invention is therefore to provide a conveyor and conveyor belt material which ensures perfect running behavior with low-noise operation and high cut resistance even in systems which are difficult to control.
  • This object is achieved according to the invention by using a spunbonded nonwoven as a reinforcement.
  • Spunbonded fabrics suitable for this purpose are advantageously thermally, mechanically and / or strengthened by a binder and have a lengthwise and crosswise direction high strength with low elongation.
  • Suitable examples of polymers from which the spunbonded nonwoven is made are polyesters and polyamides. Glass fiber fleeces are also suitable.
  • the use of the polymers is limited, provided they have sufficiently high strengths and low elongations, only because their melting point is not close to the temperature at which the spunbonded fabric either thermally solidifies or after needling on one or both sides and impregnation with a binder the drying takes place.
  • Polypropylene for example, is less suitable because its melting point is close to the drying temperature at which the needle fleece impregnated with nitrile-butadiene rubber is dried.
  • the spunbond used as a strength member advantageously has a tensile strength of at least 10 N / mm at 1% elongation.
  • the fiber titer of the spunbonded web is preferably 1 to 20 dtex, in particular 3 to ⁇ dtex.
  • the weight per unit area of the spunbonded fabric is 50 to 300 g / m 2 . preferably 175 to 225 g / m 2 .
  • one or more layers of a spunbonded fabric are needled on both sides with a staple fiber nonwoven, then the mechanically consolidated nonwoven is impregnated with a binder solution and then dried and vulcanized at a temperature of 150 ° C.
  • binders are nitrile-butadiene rubber and / or styrene-butadiene rubber latex.
  • binders it is also possible, for example, to use aqueous and / or solvent-based binders such as polyurethane, polyvinyl chloride, polyacrylate or mixtures thereof.
  • the ratio fiber: binder can preferably be 1: 2 to 2: 1, particularly preferably 1: 1 parts by weight.
  • a belt material suitable for the production of conveyor belts can have thicknesses of 1.5 to 8 mm. preferably 2.5 to 5.5 mm, and have a basis weight of 600 to 6,000 g / m 2 , preferably 2,000 to 4,000 g / m 2 .
  • the figure shows in longitudinal section an inventive strip material.
  • the band (1) consists of a spunbond (2) (shown here only in one layer).
  • the spunbond (2) is needled on both sides with a layer of staple fibers (3).
  • the tape (1) i.e. spunbond (2) and the staple fiber layers (3) needled on both sides
  • the tape (1) are completely embedded in a matrix made of a binder.
  • thermally bonded, polyester spunbonded fabric with a titer of 4.5 dtex is coated on both sides with 1,000 g / m 2 of polyester fibers, consisting of 2 parts by weight of 6.7 dtex (stack length 40 mm) and 1 part by weight. Part 17 dtex (stack length 60 mm) so needled (800 punctures per cm 2 ) that damage to the spunbond is largely avoided.
  • the base fleece is then impregnated with 100% by weight of nitrile-butadiene rubber latex, to which 25% by weight of calcium carbonate as a filler and 5% by weight of vulcanizing agent made from sulfur and zinc oxide have been added, and coagulated in an infrared shaft , dewatered, then dried at 150 ° C and vulcanized.
  • the binder-strengthened nonwoven is then sanded on both sides with emery paper, grain size 120, so that a uniformly smooth surface, a thickness of 5.5 mm and a weight of 3,500 g / m 2 is produced.
  • the product has a tensile strength of 10 N / mm at 1% elongation.
  • 200 g / m 2 of polyester staple fibers consisting of 2 parts by weight of 6.7 dtex (stack length 40 mm), are first placed between two thermally bonded polyester spunbonded fabrics, each with a weight of 200 g / m 2 and a titer of 4.5 dtex. and 1 part by weight of 17 dtex (stack length 60 mm), needled with 800 stitches per cm 2 .
  • 800 g / m 2 polyester fibers of the same mixture are also needled on both sides of this composite, likewise with 800 punctures per cm 2 .
  • the further finishing takes place as in example 1.
  • the finished product has a tensile strength of 14 N / mm at 1% elongation.
