摘　　要：以慢回弹聚醚组合料、异氰酸酯、催化剂、泡沫稳定剂、开孔剂等为原料,制备出慢回弹聚氨酯泡沫体。实验结果表明,异氰酸酯指数为0.87,发泡剂水的用量为聚醚组合料的2%,硅油用量为聚醚组合料的1%,慢回弹聚氨酯泡沫体具有较好的泡孔结构,密度和力学性能良好。Slow springback polyurethane foam was prepared from slow springback polyether compound,isocyanate,catalyst,foam stabilizer and opener.The experimental results show that the isocyanate index is 0.87,the amount of foaming agent water is 2%of polyether compound,and the amount of silicone oil is 1%of polyether compound.Slow springback polyurethane foam has better foam structure,and has good density and mechanical properties.
