Definitions

  • the present invention relates to a multilayer plastic material, a process for its preparation and its use.
  • hazard level In the field of rail vehicle construction, different fire protection regulations exist in Europe to date. In the course of its standardization, the European Union has introduced the European fire protection standard EN 45545 and has since published it as prCEN / TS 45545, which in the future will have to comply with all plastic materials that are to be used in rail vehicle construction. In the material requirements so-called hazard level (HL) are distinguished. Which hazard level the respective plastic material has to fulfill depends on the exact Operating and design class of the vehicle in which the plastic material is to be used. A hazard level 3 represents the highest, a hazard level 1 the lowest requirements with regard to the required fire protection.
  • the plastic materials are usually equipped with one or more flame retardants in order to provide them with sufficient fire protection for the respective application.
  • the flame retardants are usually distributed homogeneously in the actual plastic material, which is disadvantageous from an economic point of view, since the flame retardants are needed mainly on the surface facing the fire, but not or in much smaller dimensions inside the plastic material.
  • Flame retardants are enriched in the outermost or the outer layers.
  • EP 1 348 542 A1 describes foam-containing composite systems which consist of polyisocyanurate-blue, polyisocyanurate-imide-blue or polyimide-blue foams which are provided with intumescent or ablative intumescent formers as cover layer and optionally intermediate layers. The cover layer is subsequently applied to the initially separately prepared foam.
  • a disadvantage of these composite systems is the use of PIR foams, since these are more difficult to produce, that is to say at higher temperatures, than, for example, PUR foams. Foams and also have poorer mechanical properties.
  • Bl foams typically have densities in the range of 30 to 80 kg / m 3 and are therefore rather unsuitable for structural components because of their insufficient mechanical properties.
  • DE 196 17 592 A1 discloses plastic laminated bodies in which at least one layer a) comprises one or more synthetic resins selected from the group consisting of bitumen, epoxy resins, polyurethanes, polyolefins, silicones, rubber, synthetic thermoplastics, acrylate polymers,
  • Vinyl chloride polymers, urea-formaldehyde resins and melamine-formaldehyde resins and b) contains an intumescent mixture. Also, the method described therein is to be classified as rather expensive, since initially the production of the plastic body takes place, which is then coated by rolling, spraying, dipping, etc. Due to the method, such composite materials therefore have a rather poor surface quality.
  • WO 00/35999 A1 describes a process for producing a rigid polyurethane foam by reacting a polyisocyanate, a polyol, a halogenated reactive compound, a blowing agent, a catalyst, expandable graphite and an additional flame retardant selected from the group of phosphonate esters, phosphate esters, halogenated phosphate esters or a Combination of it.
  • the plastic materials available according to this document have a low density, are therefore only partially suitable as a structural component.
  • halogenated polyols used for the production of polyurethane foams which has a negative effect on the smoke gas toxicity.
  • a multilayer plastic material with a flexural modulus of> 250 N / mm 2 comprising a support layer of polyurethane containing red phosphorus and / or melamine and / or melamine derivatives and at least a surface associated with expanded graphite covering layer of polyurethane.
  • the cover layer contains expanded graphite in an amount of 5 to 50 wt .-%, in particular 20 to 25 wt .-%, each based on the total weight of the cover layer.
  • Expandable graphite result in insufficient fire protection.
  • larger amounts improve the extent of fire protection, but not only have a negative impact on the processability of the expandable graphite-containing polyol suspension, but also lead to a significant increase in costs for the resulting plastic material. Too high a proportion of flame retardants also leads to a deterioration of essential mechanical properties, in particular the impact strength.
  • the covering layer further contains AI (OH) 3 (such as Martinal ON320 ®), and preferably in an amount of 5 to 50 wt .-%, particularly preferably in an amount of 20 to 25 wt .-%, in each on the total weight of the topcoat.
  • AI (OH) 3 such as Martinal ON320 ®
  • the combination of at least one intumescent (expandable graphite) and an ablative (Al (OH) 3 ) flame retardant ie a water-releasing (AI (OH) 3 flame retardant has been surprising proved to be particularly advantageous.
  • AI (OH) 3 such as Martinal ON320 ®
  • the topcoat may also contain other flame retardants.
  • flame retardants commonly used in polyurethanes are suitable:
  • Phosphorus-containing flame retardants z. As phosphate esters, phosphonates, phosphinates, red phosphorus, ammonium polyphosphate b) Mineral flame retardants: z. B. Aluminum hydroxide, magnesium hydroxide, ammonium sulfate c) Nitrogen-containing flame retardants: melamine, melamine derivatives d) halogen-containing (bromine and / or chlorine) flame retardants: z. B.
  • the sum of the amounts of all flame retardants in the topcoat is in a range of 10 to 70 wt .-%, based on the total weight of the topcoat. Lower quantities result in inadequate fire protection. If the amount is greater than 70% by weight, the proportion by weight of polyurethane in the top layer is so low that the stability of the top layer is insufficient is.
  • the amount of halogen-containing flame retardants is selected so that the requirements of EN 45545 with regard to smoke toxicity are met.
  • the carrier layer contains red phosphorus and melamine and / or melamine derivatives in a weight ratio of 1: 7.5 to 1: 100, in each case based on the red phosphorus.
  • the amounts of red phosphorus are preferably such that they are 2 to 30% by weight; the amounts of melamine and / or melamine derivatives are preferably in a range of 5 to 50 wt .-%.
  • the data in% by weight relate in each case to the total weight of the carrier layer.
  • the carrier layer may also contain other flame retardants mentioned above.
  • the sum of the amounts of all flame retardants in the carrier layer is in a range of 7 to 70 wt .-% based on the total weight of the carrier layer.
  • a lower proportion (in% by weight) of flame retardants is used in the carrier layer compared to the top layer. This leads to a saving of flame retardants in comparison to those embodiments in which the flame retardant or agents are homogeneously distributed in the plastic material.
  • the carrier layer has a layer thickness in a range of 2.5 mm to 30 mm, in particular 2.5 mm to 15 mm.
  • the cover layer preferably has a layer thickness of 1 to 3 mm.
  • the cover layer is of particular importance in terms of fire protection.
  • the carrier layer should above all ensure sufficient mechanical strength of the plastic material. Low layer thicknesses of the top layer result in insufficient fire protection, whereas larger layer thicknesses increase fire protection but also result in high material costs.
  • the support layer must have a certain minimum layer thickness to ensure sufficient mechanical stability / strength, whereas large layer thicknesses are undesirable because of the associated increase in weight.
  • the multilayer plastic material has a density in a range of> 400 kg / m 3 to 1600 kg / m 3 .
  • the cover layer has a density in a range of> 700 kg / m 3 to 1600 kg / m 3 .
  • the carrier layer has a density in a range of 200 kg / m 3 to 1600 kg / m 3 .
  • the plastic material has a bending modulus in a range of 800 N / mm 2 to 4000 kN / mm 2 .
  • the carrier layer is preferably an integral foam, that is to say a foam whose outer boundaries, although consisting essentially of the same plastic material, are compressed in comparison to the interior of the plastic material, that is to say have a higher density.
  • the plastic material comprises a further expandable graphite-containing and surface-connected to the carrier layer covering layer and / or decorative layer, such as a paint or a thermoformed film.
  • a typical example in this connection is a sandwich construction of cover layer, carrier layer and cover layer, in which essentially both main boundary surfaces are protected against flame effects.
  • the object underlying the invention is achieved by a method, which is characterized in that one presents an expandable graphite-containing layer of a polyurethane material in a tool and to this a red phosphorus and / or melamine and / or melamine derivatives containing layer applying.
  • the expandable graphite-containing layer of a polyurethane material is applied by spraying in a mold, closes the mold and then applies the layer containing red phosphorus and / or melamine and / or melamine derivatives by means of back-foaming or back-injection.
  • the material of the carrier layer-depending on the process conditions- can be compressed at the boundaries of the carrier layer, thus resulting in the formation of the carrier layer as integral foam.
  • well-known polyols and isocyanates are used in the prior art.
  • the polyol component it has been found possible to replace some of these with renewable raw materials such as castor oil or other known vegetable oils, their chemical reaction products or derivatives.
  • Such an application is associated with no deterioration of the properties of the finished molded polyurethane foam body and is advantageous in that such foam body make a significant contribution to sustainability.
  • This mutual registration of the two materials optimum wetting of the flame retardant is achieved.
  • a further preferred variant of the method is characterized in that in a form a flame retardant (expandable graphite) containing foam layer presents, in particular in a tool and on this another foam material applies, which contains red phosphorus and / or melamine and / or melamine derivatives.
  • the expanded graphite-containing foam layer is preferably presented in such a way that an open mold is sprayed or sprayed in whole or in part.
  • increased thixotropy may be expedient.
  • This increased thixotropy can be achieved by exploiting the different reactivities of the starting materials (such as, for example, amines, polyethers, amino-modified polyethers, varied catalysis, etc.) for the controlled adjustment of the viscosity of the reaction mixture. From the literature, such a modification for the targeted adjustment of thixotropy is known. For example, Guether, Markusch and Cline described the use of "Non-sagging Polyurethane Compositions" at the Polyurethanes Conference 2000 (October 8-11, 2000).
  • the object underlying the invention is achieved by the use of the plastic material according to the invention in rail vehicle construction.
  • the resulting plastic material had a density of 600 kg / m 3 . It fulfills DIN 5510 but not EN 45545.
  • the resulting plastic material had a density of 1200 kg / m 3 . It fulfills DIN 5510 but not EN 45545. c) Comparative Example 3
  • the resulting plastic material had a density of 800 kg / m 3 . Although it complies with NF-F 16-101 (classification M2, F2), it only achieves HL 1 in EN 45545.
  • the plastic material obtained is not EN 45545.
  • the resulting plastic material had a density of 750 kg / m 3 (cover layer: 950 kg / m 3 , backing layer: 700 kg / m 3 ). It fulfills HL 2 in EN 45545.
  • Comparative Examples 1, 2 and 4 do not meet the European fire safety standard EN 45545. Even Comparative Example 3 only complies with Hazard Level 1. By contrast, the Example according to the invention fulfills Hazard Level 2.
