橡塑助剂-发泡剂种类

发布日期:2019-04-27 作者: 点击:

  YI、WULIFAPAOJI

  物理发泡剂种类较多,如脂肪烃、氯代烃、氟氯烃和二氧化碳气体等,自20世纪50年代,一氟三氯甲烷(CFC-11)作为聚氨酯首选的发泡剂被广泛应用,因其对大气臭氧层有破坏作用,为了保护地球生态环境,必须禁止使用CFCS类化合物。多年来国内外一直在寻找和开发理想的替代产品,替代发泡剂除考虑发泡剂本身的性质外,一般还需要对聚醚多元醇、匀泡剂、催化剂等原料进行适当调整与改善,使配方体系达到最优化,因此物理发泡剂的关键在于替代产品的开发与应用研究。到目前为止,对橡塑助剂发泡剂CFC~11的替代主要有以下四种方案。
