Description
Schaumstoff aus Polyesterharzen und Isocyanaten, insbesondere für die Verwendung als Federungskörper und als stoß- und schalldämpfendes Material Es wurde gefunden, daß man die an sich bekannten Schaumstoffe aus Polyesterharzen, und Isocyanaten in vorteilhafter Weise modifizieren kann. Während nämlich im allgemeinen die Porengröße und der Grad der Elastizität von der Art und dem Mischungsverhältnis der Rohstoffkomponenten und von der Geschwindigkeit und der Intensität des Mischvorganges abhängig sind, so daß zwar verschiedene, aber jeweils gleichförmig aufgebaute Schaumkörper mit durchschnittlich gleichartig gebauten Porengruppen auftreten, wurde gefunden, daß man durch kontinuierliche Änderung dieser Grundbedingungen in zeitlicher Reihenfolge, zweckmäßig unter Verwendung maschineller Vorrichtungen, zu Schaumkörpern kommt, in denen die Struktur bei kontinuierlichem Übergang schichtweise verändert ist und somit Schaumkörper anfallen, in denen das Material beispielsweise aus einem grobporig weichen, hochelastischen Material in ein feinblasiges, wesentlich härteres bis hartes Material übergeht.Foam made from polyester resins and isocyanates, especially for the use as a spring body and as a shock and sound absorbing material Es it was found that the foams known per se made from polyester resins, and can modify isocyanates in an advantageous manner. While in general the pore size and the degree of elasticity on the type and the mixing ratio the raw material components and the speed and intensity of the mixing process are dependent, so that although different, but each uniformly constructed foam body occur with pore groups of the same structure on average, it was found that that by continuously changing these basic conditions in chronological order, expediently using mechanical devices, foam bodies come, in which the structure is changed layer by layer with continuous transition and thus resultant foam bodies in which the material consists, for example, of a coarse-pored soft, highly elastic material into a fine-bubble, much harder to hard one Material passes.
Durch diesen Kunstgriff entstehen elastische Schaumkörper, welche sehr wertvolle und nachhaltig wirksame Federungskörper darstellen. Sie gestatten die mühelose Dämpfung selbst starker, mechanischer Stöße, sofern nur eine hinreichende Schichtdicke des Schaumkörpers gewählt wird, und sie können sehr vielfache Anwendung finden.This trick creates elastic foam bodies, which represent very valuable and sustainably effective suspension bodies. she allow the effortless damping of even strong, mechanical shocks, provided that only one is sufficient Layer thickness of the foam body is chosen, and they can be used very multiple times Find.
Ohne Ausschöpfung der gegebenen Möglichkeiten seien folgende angeführt: Unterlagen für Stoßstangen oder Lager für Motoren im Fahrzeugbau, Herstellung von Puffern aller Art, stoß- und schalldämpfende Kissen an Türen und Fenstern, Stoßkeile, Auspolsterung von Sturzhelmen, Schutzkleidung, Sportgeräten u. dgl.Without exhausting the options available, the following are listed: Supports for bumpers or bearings for engines in vehicle construction, manufacture of All kinds of buffers, shock and sound absorbing cushions on doors and windows, bumper wedges, Padding of crash helmets, protective clothing, sports equipment, etc.
Insbesondere im Auto- und Karosseriebau bringt die Verwendung von Schaumstoffen mit abgestufter Elastizität bedeutende Vorteile mit sich, da beispielsweise Türen mit Stoßkeilen aus solchem Material ständig unter weichem, federndem Druck in ihrer Lage festgehalten und durch diese wirksame Dämpfung an unerwünschten Schwingungen gehindert werden. In dieser Hinsicht haben die neuen Schaumstoffe beispielsweise wesentliche Vorteile gegenüber der Verwendung von Kautschuk, der durch Alterung bekanntlich bald hart und brüchig wird.The use of Foams with graded elasticity have significant advantages, for example Doors with wedges made of this type of material are constantly under soft, resilient pressure held in their position and through this effective damping of unwanted vibrations be prevented. In this regard, the new foams have for example significant advantages over the use of rubber, which is due to aging as is well known, it soon becomes hard and brittle.
