Description

Die Erfindung betrifft Sandwichplatten aus einer Polypropylenschaum-Kernschicht und Deckschichten aus glasmattenverstärktem Polypropylen.The invention relates to sandwich panels from a Polypropylene foam core layer and top layers made of glass mat reinforced polypropylene.

Für viele Anwendungszwecke besteht Bedarf an Leichtbauteilen, die neben einem geringen Gewicht und einem niedrigen Preis eine sehr gute Festigkeit und Stei­ figkeit aufweisen und außerdem einfach recyclierbar sein sollen.There is a need for many applications Lightweight components that are lightweight and a low price very good strength and stiffness ability and also easy to recycle should be.

Diese Anforderungen werden von den erfindungsge­ mäßen Sandwichplatten erfüllt. Sie bestehen aus
These requirements are met by the sandwich panels according to the invention. they consist of

  • A) einer Kernschicht aus Polypropylen-Partikel­ schaum einer Dichte von 0,02 bis 0,10 g.cm3 undA) a core layer of polypropylene particles foam with a density of 0.02 to 0.10 g.cm 3 and
  • B) zwei Deckschichten aus glasmattenverstärktem Polypropylen mit einem Fasergehalt von 20 bis 60 Gew.-%.B) two cover layers made of glass mat reinforced Polypropylene with a fiber content of 20 to 60% by weight.

Die erfindungsgemäße Kernschicht A besteht aus ei­ nem Partikelschaumstoff auf Basis eines Homo- oder Copolymeren des Propylens. Vorzugsweise werden Propylencopolymere verwendet mit einem Schmelz­ punkt zwischen 125 und 155°C, vorzugsweise zwischen 130 und 150°C. Als Schmelzpunkt gilt dabei das nach der DSC-Methode bestimmte Maximum beim zweiten Aufschmelzen einer Probe (Kristallitschmelzpunkt). Co­ polymerisate des Propylens mit 1 bis 30 Gew.-%, insbe­ sondere 1 bis 6 Gew.-% Ethylen und/oder eines C4- bis C6-α-Olefins sind besonders gut geeignet.The core layer A according to the invention consists of a particle foam based on a homo- or copolymer of propylene. Propylene copolymers are preferably used with a melting point between 125 and 155 ° C, preferably between 130 and 150 ° C. The melting point is the maximum determined by the DSC method the second time a sample is melted (crystallite melting point). Copolymers of propylene with 1 to 30 wt .-%, in particular special 1 to 6 wt .-% ethylene and / or a C 4 - to C 6 -α-olefin are particularly suitable.

Der Schaumstoff ist ein sogenannter Partikelschaum­ stoff, wie er durch Verschweißen von Schaumstoffparti­ keln üblicherweise mit einem mittleren Durchmesser von 2 bis 8 mm, vorzugsweise 3 bis 6 mm, erhältlich ist. Die Dichte des Schaumstoffs liegt zwischen 0,02 und 0,10 g/cm3, vorzugsweise zwischen 0,03 und 0,08 g/cm3.The foam is a so-called particle foam, as is usually available by welding foam particles with an average diameter of 2 to 8 mm, preferably 3 to 6 mm. The density of the foam is between 0.02 and 0.10 g / cm 3 , preferably between 0.03 and 0.08 g / cm 3 .

Die Dicke der Kernschicht beträgt vorzugsweise 5 bis 100, insbesondere 15 bis 40 mm.The thickness of the core layer is preferably 5 to 100, in particular 15 to 40 mm.

Die erfindungsgemäßen Deckschichten B bestehen aus glasmattenverstärktem Polypropylen. Dieses ent­ hält 20 bis 60, vorzugsweise 30 bis 45 Gew.-% Glasfa­ sern, vorzugsweise in Form von Matten. Die Matten bewirken die hohe Festigkeit des Materials. Die Länge der Glasfasern kann in weiten Grenzen zwischen etwa 2 mm und unendlich schwanken. Bevorzugt sind Matten, die aus geschnittenen Glasfaserrovings einer Länge von 5 bis 25 mm bestehen, und die durch Nadeln verfestigt wurden. Bei der Nadelung werden einige Glasfasern zerschlagen, so daß die genadelte Matte auch Anteile von kürzeren Fasern aufweist.The cover layers B according to the invention consist made of glass mat reinforced polypropylene. This ent holds 20 to 60, preferably 30 to 45 wt .-% Glasfa star, preferably in the form of mats. The mats cause the high strength of the material. The length The glass fibers can range between approximately Fluctuate 2 mm and infinitely. Mats are preferred, cut from fiberglass rovings with a length of 5 to 25 mm exist, and solidified by needles were. When needling, some glass fibers smashed so that the needled mat also shares of shorter fibers.

Das Flächengewicht der Glasfasermatten beträgt vorzugsweise 200 bis 1200 gm-2. Die Deckschichten sind vorzugsweise 1 bis 10, insbesondere 2 bis 5 mm dick.The weight per unit area of the glass fiber mats is preferably 200 to 1200 gm -2 . The cover layers are preferably 1 to 10, in particular 2 to 5 mm thick.

Die Herstellung der erfindungsgemäßen Sandwich­ platten geschieht zweckmäßigerweise durch Verpres­ sen von auf Temperaturen von etwa 210°C vorerhitzten Deckschichten mit der Kernschicht. Grundsätzlich kön­ nen die Schichten aber auch miteinander verklebt wer­ den.The production of the sandwich according to the invention plates are conveniently done by pressing preheated to temperatures of around 210 ° C Cover layers with the core layer. Basically, but the layers can also be glued together the.

Die erfindungsgemäßen Schichtstoffe können z. B. als Schalelemente in der Bauindustrie oder als Automobil­ teile, z. B. Ladeboden, Wärmedämmelemente oder schallabsorbierende Strukturbauteile verwendet wer­ den.The laminates according to the invention can, for. B. as Formwork elements in the construction industry or as an automobile parts, e.g. B. loading floor, thermal insulation elements or sound-absorbing structural components used who the.
