Microporous polyurethane anti-vibration pad for ballast bed and preparation method of microporous polyurethane anti-vibration pad
The invention discloses a microporous polyurethane anti-vibration pad for a ballast bed and a preparation method of the microporous polyurethane anti-vibration pad. The microporous polyurethane anti-vibration pad comprises a microporous polyurethane elastomer layer (10) and a geotechnical cloth layer (20) arranged on one side of the microporous polyurethane elastomer layer (10). The microporous polyurethane anti-vibration pad for the ballast bed and the anti-vibration pad have good compression resistance, creep resistance and vibration reduction performance and excellent hydrolysis resistance.
本发明公开了一种碎石道床用微孔聚氨酯减振垫及制备方法，包括：微孔聚氨酯弹性体层(10)以及设置在微孔聚氨酯弹性体层(10)一侧的土工布层(20)。本发明的碎石道床用微孔聚氨酯减振垫及作为减振垫，具有良好的抗压缩、蠕变性能、减振性能以及优异的抗水解性能。
