摘要
介绍了几种用于聚氨酯硬质泡沫生产的原料,确定了以废聚酯瓶为原料,生产聚氨酯硬质泡沫的解聚条件为:聚酯瓶料粒径3 mm左右,料瓶/醇为1∶2,醋酸锌为催化剂,温度 210 ℃。试验表明,把废聚酯瓶作为一种聚氨酯硬质泡沫的组合料来源是完全可能的。
Several kinds of wastes which can be used in the production of foamed rigid polyurethane are introduced. Experimental study has shown that to use waste polyester bottles as one of the raw (materials) is entirely possible.
