含有生物质粉末的聚氨酯原液及其制法和应用 技术领域
本发明涉及生物质粉末在聚氨酯弹性体原液中的利用方法
背景技术
聚氨酯微孔弹性体是指密度介于0.25~0.9g/cm 3的微发泡聚氨酯材料,加工简单,具有质轻、弹性好、耐磨、耐折、耐油性好等多方面的优点,可作为鞋零件、鞋底材料、承重轮胎以及汽车缓冲材料等使用,在国民经济生活中发挥重要作用。近年来随着聚氨酯原料价格飞速上涨,聚氨酯制成品生产成本不断攀升,生产企业面临利润缩减或亏损的窘境。
国内外各研究人员争相研发在聚氨酯体系中添加无机或有机填充物,以降低原料成本,并提高聚氨酯性能或改善成型的外观。
如:专利号为201210562641.7的中国专利,将废旧橡胶颗粒与聚氨酯树脂A组分、B组分一起混合,注入鞋底模具,制得填充废旧橡胶颗粒的聚氨酯鞋底,解决废旧橡胶的再利用问题,且提升鞋底的抗拉强度、耐磨性和撕裂强度等;
ZL200910232395.7中国专利以木粉作为增强剂制备家具用木粉增强聚氨酯仿木材料。

由表1,可知,本发明将生物质粉末加入聚氨酯体系中,有效解决生物质粉末的再利用问题,提升了聚氨酯弹性体的外观。使用含长链烷基支链的二元醇胺和直链线性结构的长碳链一元醇复配作为物性增强剂使用,对于含有生物质粉末的聚氨酯弹性体的物性提升效果更加明显。聚己二酸-乙二醇-1,4-丁二醇酯二醇在含有生物质粉末的聚氨酯体系中比聚己二酸乙二醇酯二醇和聚己二酸-1,4-丁二醇酯二醇表现更佳。
尽管上述实施例已经对本发明的技术方案进行了详细地描述,但本发明的技术方案并不限于以上实施例,在不脱离本发明的思想和宗旨情况下,对本发明申请专利范围的内容所作的等效变化或修饰,都应为本发明的技术范畴。
