Microporous polyurethane sound insulation pad and preparation method thereof
The invention provides a micropore polyurethane sound insulation pad and a preparation method thereof. The micropore polyurethane sound insulation pad comprises a micropore polyurethane core layer (10) and two fireproof fiber cloth layers (20) arranged on the upper surface and the lower surface of the micropore polyurethane core layer (10). The polyurethane elastomer disclosed by the invention has relatively high compression strength, good compression resistance and creep resistance, excellent hydrolysis resistance and relatively low water absorption rate; and the sound insulation pad has good fireproof and sound insulation performance on the whole.
本发明提供一种微孔聚氨酯隔声垫及其制备方法，所述微孔聚氨酯隔声垫包括微孔聚氨酯芯层(10)、设置在微孔聚氨酯芯层(10)上下表面上的两个防火纤维布层(20)。本发明聚氨酯弹性体具有较高的压缩强度，良好的抗压缩、蠕变性能，优异的抗水解性能以及较低的吸水率；并且在整体上该隔声垫具有良好的防火和隔声性能。
