摘要
以聚合MDI作为增稠剂改性团状模塑料(BMC),考察了聚合MDI用量增稠不饱和聚酯树脂(UP)和聚合MDI增稠不同质量比的不饱和聚酯树脂(UP)/环氧乙烯基树脂(VE)的混杂树脂对BMC物理性能的影响。结果表明,聚合MDI的加入能改善BMC的物理性能,聚合MDI增稠VE时,当质量分数为6%时,BMC的拉伸、弯曲和冲击强度均达到最大,收缩率最小;聚合MDI增稠UP/VE混杂树脂时,UP/VE质量比在25/45到35/35时,能获得最小的收缩率和力学性能。
Polymeric MDI was used as a thickening agent to modify bulk molding compounds(BMC),and the effects of the addition level of polymeric MDI and the mass ratio of UP/VE on the mechanical properties of modified BMC were investigated.The results showed that shrinkage was minimum and mechanical properties was the best when the polymeric MDI content was 6% and the mass ratio of UP/VE was from 25/45 to 35/35.
