POLYURETHANE USEFUL FOR ORTHOPEDICS EXTERNAL FIXING SYSTEM IN COMPLEX ENVIRONMENT AND PREPARATION METHOD THEREOF
摘要：
A polyurethane used for orthopedics external fixing system in complex environment is obtained by reaction of mixture of polyether polyol with modified isocyanate in the weight ratio of 1:0.6-0.75. The modified isocyanate is obtained by reaction of polyphenyl polymethylene isocyanate with polyether diol. The components and corresponding weight percents of the mixture of polyether polyol are as follows: 60-65% polyether polyol as shown by formula (I), in the formula, m is an integer of 7-15, R represents mannitol, sucrose or pentaerythritol; 0.3-1% catalyst; 0.1-2% foam stabilizer; 0.1-2% or 3-20% foaming agent; 25-40% filler and 0.5-2% functional auxiliary agent. The method of producing the polyurethane is also provided.
摘要（中）：

通过将聚醚多元醇与改性异氰酸酯的混合物以1:0.6-0.75的重量比反应得到复合环境中用于整形外科固定系统的聚氨酯。 改性异氰酸酯通过聚苯基聚亚甲基异氰酸酯与聚醚二醇的反应得到。 聚醚多元醇混合物的组分和相应重量百分比如下：式（I）所示的60-65％聚醚多元醇，式中m是7-15的整数，R代表甘露糖醇，蔗糖或季戊四醇 ; 0.3-1％催化剂; 0.1-2％泡沫稳定剂; 0.1-2％或3-20％发泡剂; 25-40％填料和0.5-2％功能助剂。 还提供了生产聚氨酯的方法。
