Description
技术领域
本发明涉及一种生物可降解的纺丝材料,具体涉及一种聚乳酸、二氧化硅气凝胶复合纺丝母粒及其制备方法。
背景技术
“碳达峰、碳中和”成为中国乃至全球环境可持续发展的目标,在这种背景下,绿色环保与减碳理念将持续伴随纺织服装行业的发展,例如特步就推出全新环保新品“聚乳酸T恤”,利用全生物来源的材料聚乳酸纺丝纤维最终制成可堆肥降解的服装;润益(嘉兴)新材料有限公司也使用聚乳酸开发出各类纤维制品。
二氧化硅(SiO2)气凝胶又被称之为“蓝烟”,其组成中超过96%都是气体,是目前世界上最轻的固体。除密度极低以外,SiO2气凝胶还具有低导热率、高孔隙率、高比表面积、低介电常数等独特性质,目前在航空航天、建筑保温、医学及催化剂领域均有着广泛的应用场景。
利用聚乳酸结合SiO2气凝胶制备复合纺织物,除具备生物降解、天然亲肤、天然抗菌与阻燃等特点外,可进一步降低产品密度,提高保温效果,可应用于高寒地区棉服、棉被的填充物。

优选地,所述二氧化硅气凝胶粉体,粒径为5~20微米,孔隙率大于90%。
另外,本发明还提供了一种聚乳酸、二氧化硅气凝胶复合纺丝母粒的制备方法,包括如下步骤:
(1)真空干燥:将聚乳酸在在温度小于PLA切片的玻璃化转变温度条件下进料,进料后冷却0.5h,然后在60℃干燥1h、在70℃条件下干燥4h、在80℃条件下干燥1h、在130℃条件下干燥6-7h,干燥真空度≤-0.098MPa;烘干后的含水率≦15×10-6,波动值≦3×10-6,密封降温保存;
(2)冷冻研磨:将干燥后的聚乳酸进行液氮冷冻研磨过筛,最终得到目数在10-100目区间的聚乳酸粉末;
(3)混合活化:按比例将PLA粉末、SiO2气凝胶粉末、聚硅氧烷季铵盐-16与极性酰胺蜡加入高混机,在40℃温度条件下,密封高速搅拌30分钟,混合活化均匀;
(4)造粒:使用平行同向双螺杆造粒机组,设置螺杆温度135-180℃,模头温度185℃,螺杆转速250rpm,挤出后风冷拉条,最后切粒,真空密封包装保存。
采用了上述技术方案后,本发明的有益效果是:
本发明中,采用聚乳酸与二氧化硅气凝胶作为主体造粒,同时结合了聚乳酸的生物分解性、抗菌性能、阻燃性能等及气凝胶良好的阻热性能,所生产的纤维具备低密度、低导热系数、生物降解、天然亲肤、天然抗菌与阻燃等特点可应用于高寒地区棉服、棉被的填充物。
