摘　　要：以低气味、低挥发性有机物(VOC)聚醚,具有自催化作用的交联剂,增强剂,具有除醛功能的催化剂,低VOC硅油,开孔剂为A组分,改性MDI(二苯基甲烷二异氰酸酯)为B组分,制备了汽车座椅。研究了交联剂、增强剂、催化剂以及开孔剂对制品性能的影响,并检测了产品的醛值和VOC含量。结果表明,交联剂、增强剂、催化剂、开孔剂的质量分数分别为2.0%、6%、0.8%、1.5%时,产品的力学性能最好。由该组合料生产的产品气味等级能达到2.5,VOC能满足主机厂标准要求。The car seat was prepared by using the polyether with low odor and low volatile organic compounds (VOC),crosslinking agent with self-catalytic effect,reinforcing agent,catalyst with aldehyde scavenging function,low VOC silicone oil,cell opening agent as A component,the modified MDI (diphenylmethane diisocyanate) as B component.The influence of the crosslinking agent,reinforcing agent,catalyst,cell opening agent on the performance of the product was investigated,the aldehyde values and VOC content of the product were also determined.The results show that when the mass fraction of the crosslinking agent,reinforcing agent,catalyst,cell opening agent is 2.0%,6.0%,0.8%,1.5% respectively,the mechanical performance of the product is optimal.The odor level of the product prepared by using such system can achieve 2.5,and its VOC can meet the standard requirements of the main engine plant.
