摘要
采用聚酯多元醇、匀泡剂、扩链剂、发泡剂等混合而成的组合料与异氰酸酯-聚酯多元醇的预聚物,经发泡浇注机反应注射成型,制备聚氨酯微孔弹性体,考察了聚酯多元醇、扩链剂、预聚物NCO含量以及表观密度对聚氨酯微孔弹性体耐折性能的影响。研究结果表明,合成时采用的聚酯二醇分子量越高,聚氨酯微孔弹性体的耐折性能越好;当聚酯二醇的相对分子质量相同时,以PBA为聚酯二醇合成的聚氨酯微孔弹性体耐折性能最佳;当聚酯多元醇MX-1的添加量为5%~10%时,聚氨酯微孔弹性体具有较好的耐折性能与熟化性能,提高扩链剂的添加量、提高预聚体NCO含量和降低产品表观密度均会导致聚氨酯微孔弹性体耐折性能下降。
The microcellular polyurethane elastomer was prepared by polyester polyol,foam stabilizer,chain extender,foaming agent and the polyester-type prepolymer,etc.through reaction injection molding.The influences of polyester polyol,chain extender,NCO content of prepolymer and molded density on the folding resistance of PU elastomers were investigated.The research result showed that the folding resistance increased with the increase of the molecular weight of polyester diol.When the molecular weight of the polyester diol was the same,PBA based PU had the best folding resistance.When the content of polyester polyol MX-1 was 5%~ 10%,the PU had good folding resistance and curing performance.The folding resistance decreased with the increase of the dosage of chain extender and NCO content of prepolymer,and the decrease of apparent density.
