Description

一种耐寒软质中低密度聚氨酯树脂
技术领域
本发明涉及一种聚氨酯鞋用树脂，尤其涉及一种耐寒软质中低密度聚氨酯树脂，属于聚氨酯树脂制备技术领域。
背景技术
由于聚氨酯鞋底具有轻便耐磨、弹性好、不断底、防滑、防油、穿着舒适等特点，其越来越受到消费者欢迎。我国拥有世界上最大的制鞋产业，鞋的产量占到世界总产量的50％；但使用聚氨酯弹性体作为鞋底材料仅占总鞋底材料的6％左右，对比欧美国家25％以上的占有率，市场份额相对较小。因此可见，聚氨酯弹性体材料在国内市场有着巨大的潜力。
聚氨酯发泡一般为组合料，包括多元醇组合料、异氰酸酯组合料，组分依不同组合成份、不同比例于灌注机混合灌注于鞋底模内发泡成型，制造出不同发泡密度，不同物性要求的产品。
现有技术中，聚氨酯鞋用树脂的多元醇组合料主要是由聚酯多元酸或聚醚多元醇与整泡剂、交联剂、水混合而成，异氰酸酯组合料主要包括二苯基甲烷二异氰酸酯、聚酯多元醇或聚醚多元醇。按照普通配方制造的普通鞋底在密度低的情况下难以保持耐寒软质特性，所以，解决鞋底在密度低的情况下难以保持耐寒软质的技术难题是现在鞋业领域的重要课题。
发明内容
本发明的目的是提供一种耐寒软质中低密度聚氨酯树脂，以解决上述现有技术中尚未解决的难题。
本发明采用的技术方案为：一种耐寒软质中低密度聚氨酯树脂，其特征在于：所述聚氨酯树脂各组分比例按重量份计为A组分：75～88份聚酯多元醇、7～8份二元醇扩链剂、3～8份催化剂、0.3～1.2份有机硅匀泡剂和0.35～0.65份水；B组分：70～75份多异氰酸酯、30～32份聚酯多元醇、5～10份的聚醚多元醇。
进一步地，所述聚酯多元醇官能度为2.0～2.2，分子量1600～1800，酸值为0.6～0.7mgKOH/g。
进一步地，所述多异氰酸酯为4，4-二苯基甲烷二异氰酸酯或改性4，4-二苯基甲烷二异氰酸酯的一种或两者混合物。
进一步地，所述聚醚多元醇官能度2.0～2.2，分子量为3800～4200。
进一步地，所述催化剂中含有固体含钛化合物和碱金属，含钛化合物和碱金属的摩尔比为1～10∶0.1～1。
有益效果：本发明的聚氨酯鞋用树脂，在中低密度下还能保持软质耐寒的特性；本发明的产品制备原料易得，方法简单，可重复性好，成本低廉，可以实现大批量生产；本发明的产品生产原料无毒无害，绿色环保。
