Definitions
- the invention relates to a conveyor system with a conveyor belt, comprising a support-side and running-side cover plate, at least one attached between the support side and run-side cover plate further, i. additional, layer composed of at least one polymeric material, and also with drums, carrying rollers and support frames, wherein the conveyor system forms a material-promoting upper strand with a feed point for the conveying material and a mostly material-free lower strand.
- a conveyor system with a conveyor belt, comprising a support-side and running-side cover plate, at least one attached between the support side and run-side cover plate further, i. additional, layer composed of at least one polymeric material, and also with drums, carrying rollers and support frames, wherein the conveyor system forms a material-promoting upper strand with a feed point for the conveying material and a mostly material-free lower strand.
- there are also conveyor systems which are additionally loaded in the lower section.
- the support-side and running-side cover plate of a conveyor belt as the core component of a
- Conveyor systems usually consist of a film or a woven fabric or preferably of a rubber mixture containing at least one rubber component or a rubber component blend, at least one crosslinking agent or a
- a crosslinking system comprising a crosslinking agent and an accelerator, and usually further Mischingingredienzien, in particular at least one filler and / or at least one processing aid and / or at least one
- Anti-aging agents and / or at least one plasticizer and / or other additive e.g., fibers, colored pigments.
- brominated compounds Due to the vulcanization of the rubber compound, the conveyor belt experiences the required elastic properties. In addition, flame retardants are usually added to the two cover plates to meet flame and fire protection requirements. So far, brominated compounds have been used both for steel cord conveyor belts and for fabric conveyor belts. These guaranteed the use of the conveyor system even in very different climatic zones. In particular for steel cord conveyor belts when used in countries with in some cases very low temperatures, cold-flexible rubbers such as, for example, butadiene rubber or styrene-butadiene rubber are used, which have been rendered flame-retardant with brominated compounds. Even in small quantities, brominated compounds are good flame-retardant, but are considered to be so-called PBT substance (persistent, bioaccumulating, toxic) and may therefore according to the latest
- flame retardants such as Al (OH) 3 or trioctyl phosphate (TOF) or chlorinated paraffin
- TOF trioctyl phosphate
- chlorinated paraffin use, which then have to be used in higher concentrations and in particular the other properties such as tensile strength, elongation, tear propagation, abrasion, etc . influence negatively.
- Another well-known flame retardant is antimony trioxide. It often acts as a synergist in combination with halogenated flame retardants.
- the mechanism of action of halogen-containing flame retardants is based on an interruption of the radical chain mechanisms during the gas phase combustion process.
- antimony trioxide under thermal stress facilitates the decomposition of halogenated compounds through the formation of halogenated antimony compounds, which in turn react with the OH and H radicals in the flame.
- Halogenated, in particular brominated, flame retardants have the disadvantage that polyhalogenated compounds are formed during combustion. These have a toxic effect, are poorly biodegradable and accumulate in the diet.
- Antimony trioxide is called
- the object of the invention is to provide a conveyor system, the conveyor belt is characterized by a sufficient
- the support-side (support side) cover plate and / or the running side (running side) cover plate contains at least one flame retardant, wherein the flame retardant is free of bromine or bromine compounds.
- Such flame retardants can thus be used as a complete alternative to the common flame retardants or at least lead to the fact that the amount of the above-mentioned poorly beneficial brominated flame retardants can be significantly reduced.

- the running side and / or the carrying side still each contain at least one further flame retardant.
- This is preferably a flame retardant which contains antimony and / or which one Antimony compound is.
- the amount of the further, antimony-containing flame retardants in this case the amount of the further, antimony-containing flame retardants.
- the amount based in each case on the total amount of the running side and / or the supporting side, is preferably 0 to 5 phr, more preferably 0 to 3 phr and most preferably 0 phr.
- the further flame retardant may also be chloroparaffin, preferably in amounts of from 0 to 25 phr, more preferably from 0 to 15 phr.
