一种聚氨酯泡沫阻尼材料及其制备方法
摘要：
本发明涉及一种聚氨酯泡沫阻尼材料及其制备方法，本发明中的聚氨酯泡沫阻尼材料密度为70～170kg/m3，阻尼系数≥0.3，制备方法简单。本发明以辣椒废弃物为原料，充分利用了工、农业生产中产生的废弃物，避免了资源的浪费，减轻了石油资源的压力，减少了生物质废弃物处理不当带来的环境污染，同时可以制得一种综合性能好的聚氨酯泡沫阻尼材料。
摘要（英）：

The invention relates to a polyurethane foam damping material and a preparation method for the same. The density of the polyurethane foam damping material is 70-170kg/m3, the damping coefficient of the material is larger than or equal to 0.3, and the preparation method is simple. The polyurethane foam damping material is made of pepper waste, and makes the best of waste generated during industrial and agricultural production, so that resource waste is avoided, pressure of petroleum resources is relieved, and environmental pollution caused by improper treatment of biomass waste is reduced. Besides, the polyurethane foam damping material with good comprehensive performances can be prepared.
