Definitions

  • the invention relates to a conveyor belt, comprising at least one reinforcing layer made of rubberized fabric or rubberized cords, a support-side rubber cover plate and a non-stick coating of ultra-high molecular weight polyethylene (UHMW-PE) on the supporting surface.
  • UHMW-PE ultra-high molecular weight polyethylene
  • Such conveyor belts are known, for example, from WO 02/094692 A1.
  • a film of ultra-high molecular weight polyethylene is applied.
  • the conveyor belts according to WO 02/094692 A1 are characterized by a practicable, durable and durable non-stick coating. The life of such straps is extended.
  • load-bearing rubber cover layer is based on oil-resistant nitrile rubber or chloroprene rubber, sufficient adhesion between non-stick coating of ultra-high molecular weight polyethylene and load-bearing rubber cover layer can not be achieved. It comes to the separation of the layers.
  • the invention is therefore based on the object to provide a conveyor belt, which shows a high flame retardancy, sufficient temperature resistance, high oil and grease resistance and reduced contamination of the bearing surface.
  • This object is achieved according to the invention in that the support-side rubber cover plate based on nitrile rubber or chloroprene rubber and between the On the rubber side cover plate and the non-stick coating a rubber layer based on styrene-butadiene rubber is arranged as a bonding layer.
  • the basic idea of the invention resides in the fact that the layers of ultrahigh molecular weight polyethylene and rubber plates of nitrile or chloroprene rubber, which are normally not adhered, are bonded via a layer of a further rubber mixture based on styrene-butadiene rubber.
  • a layer of a further rubber mixture based on styrene-butadiene rubber In this way it is possible to combine the good properties of nitrile and chloroprene rubber in terms of temperature and oil resistance with the properties of a provided with an anti-adhesive layer conveyor belt. Materials do not stick to the belt surface, the cleaning effort is reduced and you can time consuming, expensive and the life of the belt shortening belt scraper, z. B. carbide, dispense.
  • the conveyor belt according to the invention additionally has good flame retardancy.
  • the service life of the straps is further increased by reducing the wear on the bearing surface, even with a reduction in the existing rubber cover plate thickness.
  • the conveyor belts according to the invention can, for. B. for the promotion of oil or fat products, eg. B. in grain handling ports, are used advantageously.
  • One possible area of use is, for example, the promotion of soybean meal in soybean oil production.

  • the conveyor belt according to the invention has one or more reinforcement layers of rubberized fabric or rubberized cords.
  • the straps according to the invention can withstand a more stringent flame retardancy test, in which wear-resistant and possibly present running rubber cover layers are removed, the gumming of the fabric or of the cords is preferably based on styrene-butadiene rubber.

  • the conveyor belt has a running-side rubber cover plate based on nitrile or chloroprene rubber. For technical reasons, it makes sense if the support and running side cover plates are based on the same rubber.
  • the conveyor belt has lateral solid rubber edges, so that the reinforcement layer is covered laterally.
  • These solid rubber edges are made for ease of manufacture of the conveyor belt, preferably of a rubber mixture based on the same type of rubber as the running and supporting side rubber cover plates.
  • the non-stick coating of the conveyor belt preferably has a thickness of min. 0.2 mm, so that a good anti-adhesive effect and a high abrasion resistance are ensured.
  • the non-stick coating has a thickness of 0.2 to 0.3 mm, in order not to adversely affect the elasticity and trough capacity of the belt with good anti-adhesive effect.
  • the conveyor belt according to the invention can be produced by methods known to the person skilled in the art, as described, for example, in WO 02/094692 A1. First the fabric or cord layers are gummed (calendered) with the help of calenders with a rubber mixture. Then, a belt blank is produced from the un-vulcanized layers of rubberized fabric or corduroy and, if present, running side cover plate mixtures. On the support-side unvulcanized mixture for the cover plate, a film made of UHMW-PE or a powder made of UHMW-PE and the composite is vulcanized continuously or discontinuously, wherein the film or the powder of UHMW-PE forms the non-stick coating and firmly adhering to the connecting side cover plate is connected.

  • On the support-side cover plate 2 is a
  • Rubber layer 5 based on styrene-butadiene rubber, which acts as a bonding layer between the support-side rubber cover plate 2 and the outwardly facing non-stick coating 6 made of UHMW-PE.
  • the conveyor belt according to FIG. 1 was tested with regard to its properties; in doing so it showed a high oil and grease resistance, a particularly high flame retardancy and a sufficient temperature resistance. Carrying on the belt, even sticky or oily material could be easily and completely removed due to the non-stick coating. There were no signs of detachment between the carrier side cover layer 2 and non-stick coating 6. In a conveyor belt similar structure, but without the rubber layer acting as a bonding layer 5, no adhesion between the support side cover plate 2 and non-stick coating 6 could be achieved, thus no anti-adhesive layer remained on the conveyor belt and transported goods remained stuck. The residues could only be removed with elaborate and expensive wiper systems, which also strongly attacked the belt mechanically and shortened the service life of the belt.

Abstract

L'invention concerne une courroie transporteuse qui présente au moins une couche de renfort en tissu caoutchouté ou câbles caoutchoutés (1a, 1b, 1c), une plaque (2) de recouvrement en caoutchouc située côté porteur et un revêtement antiadhérent (6) en polyéthylène à poids moléculaire ultraélevé (UHMW-PE) sur la surface située du côté porteur. Pour obtenir une haute ignifugation, une tenue suffisante aux hautes températures, une résistance élevée aux huiles et aux graisses et un encrassement réduit de la surface située du côté porteur, la plaque de recouvrement en caoutchouc (2) située du côté porteur est à base de caoutchouc nitrile ou de caoutchouc au chloroprène, et une couche de caoutchouc (5) à base de caoutchouc au styrène-butadiène qui sert d'intermédiaire d'adhérence est disposée entre la plaque (2) de recouvrement en caoutchouc située du côté porteur et le revêtement antiadhérent (6).
