The invention discloses a polyurethane/shear thickening gel composite material and application of the polyurethane/shear thickening gel composite material in an automobile seat, and the polyurethane/shear thickening gel composite material is prepared from the following components in percentage by weight: 10 to 30 percent of shear thickening gel and 70 to 90 percent of polyurethane; the polyurethane comprises a material A and a material B, and the weight ratio of the material A to the material B is 1.2-1.6. The polyurethane/shear thickening gel composite material is adopted to manufacture a buffering energy-absorbing block, the buffering energy-absorbing block is embedded into cushion foam of a seat or fixed to a cushion framework or a vehicle body metal plate, and the buffering energy-absorbing block is located in the front of a cushion. The anti-diving seat can become hard from soft when being impacted and absorb collision energy, and meanwhile the anti-diving function of the seat is achieved.
本发明公开了一种聚氨酯/剪切增稠凝胶复合材料及其在汽车座椅中的应用,本发明所述的聚氨酯/剪切增稠凝胶复合材料,按重量百分比计包括10~30%的剪切增稠凝胶和70~90%的聚氨酯;所述聚氨酯包括A料和B料,所述A料和B料的重量比为1.2~1.6。采用上述的聚氨酯/剪切增稠凝胶复合材料制成缓冲吸能块,将所述缓冲吸能块嵌入座椅的坐垫泡沫中或将所述缓冲吸能块固定于坐垫骨架或车体钣金上,且所述缓冲吸能块位于坐垫前部。其能够在受到冲击时由柔变硬,吸收碰撞能量,同时实现座椅的防下潜功能。
