Title (EN) RESIN COMPOSITION FOR DAMPING MATERIALS
(FR) COMPOSITION DE RÉSINE DESTINÉE À DES MATÉRIAUX D’AMORTISSEMENT
Abstract:
(EN) [Problem] The present invention is to provide a composition which can easily form a polyurethane resin which exerts particularly excellent damping properties in an operating temperature range. [Solution to Problem] A resin composition for damping materials, including a polyol-containing component (A) and a polyisocyanate (B), in which the polyol-containing component (A) contains a castor oil and in which when the composition is cured, the peak on its Tan δ curve is 0.7 or more and the temperature for the peak is in a range of -10°C to 100°C.
(FR) Le problème décrit par la présente invention est de fournir une composition qui peut facilement former une résine de polyuréthane qui exerce des propriétés d'amortissement particulièrement excellentes dans une plage de température de fonctionnement. A cet effet, l'invention concerne une composition de résine pour des matériaux d'amortissement, comprenant un composant contenant un polyol (A) et un polyisocyanate (B), dans laquelle le composant contenant un polyol (A) contient une huile de ricin et dans laquelle, lorsque la composition est durcie, le pic sur sa courbe de Tan δ est supérieur ou égal à 0,7 et la température pour le pic est comprise dans une plage de -10 °C à 100° C.
