Description

间歇板材阻燃组合聚醚
技术领域
本发明属于聚氨酯硬泡的主要原料。
背景技术
组合聚醚是聚氨酯硬泡的主要原料之一，又称白料，与聚合MDI共称黑白料。组合聚醚由聚醚单体、匀泡剂、交联剂、催化剂、发泡剂等多种组份组合而成。间歇板材组合聚醚需要具有良好的流动性，同时熟化时间要尽量短，否则生产效率太低，而且自由泡密度要尽量小，否则影响模压效果。近年来要求阻燃等级提高，不但延长了熟化时间，密度也增大了许多，目前氧指数26以上的组合聚醚，熟化时间基本在60分钟左右，模压密度在50左右，而且由于增加了阻燃，流动性变差，很难充满模具。
发明内容
本发明的目的是克服上述不足问题，提供一种间歇板材阻燃组合聚醚，流动性好，熟化时间短，自由泡密度小，模压效果好。
本发明间歇板材阻燃组合聚醚，其由下述原料按所述用量配制而成，
本发明间歇板材阻燃组合聚醚的制法：将各种原料按比例加入单螺旋搅拌罐，加入顺序，要最后加入一氟二氯乙烷，保持室温在15度-25度之间，全部材料加入后，开启搅拌装置，搅拌5－10分钟，然后静止5－10分钟，再搅拌10－20分钟，最后经过滤后，进行分装使用。
   本发明与同类产品相比，具有显著的优越性：聚醚成本低，配方简单，使用时，本发明产品自由泡密度在23公斤/立方米，模压密度在38公斤/立方米左右，氧指数在26.5以上，熟化时间在30分钟，满足了良好的流动性，同时熟化时间短，生产效率大幅提高，而且自由泡密度足够小，模压效果好。
具体实施方式
下面结合具体实施例对本发明作进一步详细说明，但本发明并不局限于具体实施例。
间歇板材阻燃组合聚醚，具体配方如下:
将各种原料按比例加入单螺旋搅拌罐，加入顺序要最后加入一氟二氯乙烷，其他原料可以任意顺序加入，保持室温在15度-25度之间，全部材料加入后，开启搅拌装置，搅拌10分钟，然后静止10分钟，再搅拌20分钟，最后经过滤后，进行分装使用。
施工时，与黑料配合进行聚氨酯发泡，自由泡密度在23公斤/立方米，模压密度在38公斤/立方米左右，氧指数在26.5以上，熟化时间在30分钟。
