Definitions
- the invention relates to an article with a base body made of a polymeric material having elastic properties, in particular a metal-rubber element for S rail vehicles.
- Rail vehicles have metal-rubber elements in various designs as suspension systems that are essential for the comfort and safety of
- vulcanized rubber mixtures which are predominantly based on natural rubber (NR) and / or polyisoprene rubber (IR).
- NR natural rubber
- IR polyisoprene rubber
- Fire protection which is particularly evident in the stricter fire safety standard EN45545, results in an increased demand for fire protection-optimized polymer articles.
- additional outer layer containing a vinyl acetate-containing thermoplastic polymer, a double bond-containing, unsaturated elastomer and at least one flame retardant to use.
- This additional outer layer must be vulcanized onto the component or onto the basic body of the component at comparatively high vulcanization temperatures via a specifically controlled vulcanization process.
- a vulcanization process must be carried out twice in succession. This does not just mean one
- the object of the invention is now to provide an article, in particular a metal-rubber element, which is characterized by an optimized fire protection performance to meet the stringent requirements, in particular those described in EN-45545. At the same time, the necessary physical
- the article in particular the metal-rubber element, a body made of a polymeric material with elastic
- main body is partially or completely composed of two layers of the polymeric material and wherein each of the first layer and the second layer of a rubber mixture and wherein the second layer to the
- the inwardly lying first layer of the previously used rubber compound can be constructed and thus continue to take over the majority of the spring properties for which a mechanically highly stressed material is essential.
- the second, outward facing layer so to speak, takes over the fire protection and plays a subordinate role for the wearing characteristics.
- the second layer protects the exposed surface of the metal-rubber part during installation.
- the second layer may extend to the entire article, so that the main body is made up entirely of two layers or else the second layer is only located on certain, exposed areas of the metal-rubber element, which are particularly prone to fire. In the latter case, the body is only partially composed of two layers.
- the first layer of the base body is a rubber mixture, which is preferably thermoplastic-free, containing at least one rubber component and further mixture ingredients.
- Rubber components which may be mentioned in particular are: ethylene-propylene rubber (EPM), ethylene-propylene-diene rubber (EPDM), nitrile rubber (NBR), (partially) hydrogenated nitrile rubber (HNBR), fluorinated rubber (FKM), chloroprene rubber.
- Chlorobutyl rubber (CIIR) .J3romated copolymer of isobutylene and paramethylstyrene (BIMS), butadiene rubber (BR) ⁇ Chlorinated polyethylene (CM) and / or
- CSM Chlorosulfonated polyethylene
- the aforementioned types of rubber may be unblended.
- a blend in particular in conjunction with one of the abovementioned types of rubber, for example an NR / IR blend, NR / BR blend or a BR / SBR blend, is also possible.
- Rubber component used for a metal-rubber element Rubber component used for a metal-rubber element.
- the usual compounding ingredients include at least one crosslinker or crosslinker system (crosslinker and accelerator).
- Mixture ingredients are usually still a filler and / or a
- Processing aids and / or a plasticizer and / or an aging inhibitor and optionally further additives for example color pigments, reinforcing fibers.
- the second layer of the base body is also one
- Rubber mixture which is preferably thermoplastic free, containing at least one
- Rubber components are in particular: ethylene-propylene rubber (EPM), ethylene-propylene-diene rubber (EPDM), nitrile rubber (NBR),
- FINBR (partially) hydrogenated nitrile rubber
- FKM fluoro rubber
- CR chloroprene rubber
- NR natural rubber
- SBR styrene-butadiene rubber
- IR isoprene rubber
- HR butyl rubber
- BIIR bromobutyl rubber
- CIIR chlorobutyl rubber
- Brominated copolymer of isobutylene and paramethylstyrene (BIMS), butadiene rubber (BR) ⁇ Chlorinated polyethylene (CM) and / or chlorosulfonated polyethylene (CSM).
- BIMS isobutylene and paramethylstyrene
- BR butadiene rubber
- CM Chlorinated polyethylene
- CSM chlorosulfonated polyethylene
- the aforementioned types of rubber may be unblended.
- the use of a blend, in particular in conjunction with one of the abovementioned types of rubber for example an NR / IR blend, NR / BR blend or a BR / SBR blend, is also possible.
- the second layer is selected if the second layer as
- Rubber component also contains NR and / or IR.
- the rubber composition of the second layer additionally contains at least one
- Flame retardants This is preferably a halogen-free
- Flame retardant or one which has the lowest possible halogen content so that the amount of toxic flue gases remains low in case of fire.
- Stannates such as zinc stannate or zinc hydroxystannate
- hydroxides such as magnesium hydroxide or aluminum hydroxide
- cyanurates such as
- Resorcinoldiphosphat or aromatic polyphosphates nitrogen-containing components such as ammonium phosphate, Intumeszenzgemische, carbonates such as calcium carbonate or magnesium carbonate, antimony trioxide, hollow microspheres, preferably in unexpanded form, or expandable graphite in question.
- nitrogen-containing components such as ammonium phosphate, Intumeszenzgemische, carbonates such as calcium carbonate or magnesium carbonate, antimony trioxide, hollow microspheres, preferably in unexpanded form, or expandable graphite in question.
- Intumescent mixtures expand to foams. They are used to protect combustible materials such as plastics or wood, but also steel, which loses its strength at elevated temperatures, against the effects of heat and fire.
- the flame retardants can be used alone or in combination.
- Another object is to provide a method for producing an article, in particular a metal-rubber element, which is characterized by an optimized
- the rubber mixture of the second layer of the base body can be inserted in a preferred embodiment, the first in the form of a compression blank in the Vulkanisierform. Subsequently, the rubber mixture of the second layer is introduced into the vulcanizing mold. This can preferably be done by a transfer method or an injection method.
- the two rubber mixtures can be injected simultaneously or one after the other, it being advantageous in the latter case to use only the
- Fig. 1 shows a section through a metal-rubber element.
- the metal-rubber element has metal parts 3 at different positions.
- the polymeric base body with elastic properties is composed of two layers.
- the rubber mixture of the first layer 1 is in this case essentially responsible for the actual function of the metal-rubber element, while the rubber mixture of the second layer 2 additionally contains a flame retardant and is attached to the exposed areas, which are particularly at risk of fire.
