摘要 以环戊烷/异戊烷为发泡剂,采用本厂生产的聚醚制备聚氨酯硬泡组合料。对聚醚、匀泡剂、催化剂、环戊烷/异戊烷配比进行选择,制得的组合料发泡具有良好的流动性,泡沫制品较之以环戊烷为发泡剂制得的泡沫密度低,性能略优,有利于降低生产成本。 A polyether premix for polyurethane was prepared for our factory made polyether polyols with i/c-Pentane as a blowing agent.The kinds of polyether polyols,foam stabilizers and catalysts were selected.The premix is provided with good fluidity.It shows that,comparing with c-pentane foaming system,in using i/c-Pentane foaming system,the foam density is dropped,physical properties are improved and the cost is lowered.
