Abstract

The invention provides a vibration and energy absorption polyurethane material and a preparation method thereof. The polyurethane material is prepared by reacting raw materials comprising an isocyanate reactive component A and an isocyanate component B, the isocyanate reactive component A comprises a polyalcohol component A1, a foaming agent A2 and a catalyst A3, wherein the polyalcohol componentA1 comprises bio-based polyol of which the mass proportion is not lower than 50%. The prepared vibration and energy absorption polyurethane material is relatively good in vibration and energy absorption effect, excellent in comprehensive performance, green and environment-friendly. The preparation method is simple, convenient and easy.

Description

technical field [0001] The invention relates to a shock-absorbing and energy-absorbing polyurethane material, in particular to a bio-based shock-absorbing and energy-absorbing polyurethane material, as well as a preparation method and application of the material. Background technique [0002] With the continuous development of modern society, the hazards caused by vibration and noise have attracted more and more attention. These vibrations and noise not only endanger human physical and mental health, but also cause damage to mechanical equipment, instrumentation pipelines, etc. In order to eliminate the adverse consequences caused by vibration and noise, various control techniques must be used, among which the most widely used and most effective method is to use high-damping shock-absorbing materials. [0003] High-damping shock-absorbing materials are usually polymer materials, which have dual characteristics of elasticity and viscosity, which are determined by the molecula...
