Description

一种抗撕裂医用无纺布材料
技术领域
本发明涉及无纺布技术领域，尤其涉及一种抗撕裂医用无纺布材料。
背景技术
医用无纺布是一种非织造布，没有经纬线，只是将纺织短纤维或者长丝进行定向或随机排列，形成纤网结构，然后采用机械、热粘或化学等方法加固而成。它与传统的纯棉机织纺织品相比，医用无纺布具有防潮、透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、价格低廉、可循环再利用等优势，非常适用于医学领域，广泛应用于生产口罩、手术帽、一次性手术衣、一次性医用床单、产妇包、尿布等产品。但是医用无纺布的抗撕裂性能差、易破损，不能满足人满需求。
发明内容
基于背景技术存在的技术问题，本发明提出了一种抗撕裂医用无纺布材料，抗撕裂性能优异，抗菌和抗静电效果好。
本发明提出一种抗撕裂医用无纺布材料，其原料按重量份包括：聚氨酯纤维80-100份，改性钛酸铈5-15份，聚乙烯乙二醇蜡1-3份，抗菌剂1-2份，抗静电剂1-2份，抗氧剂0.5-1.5份。
优选地，改性钛酸铈采用如下工艺制备：将介孔钛酸铈、纳米玻璃纤维、偶联剂加入丙酮溶液中，调节PH值后，加入聚甲基丙烯酸甲酯和聚乙烯醇，经恒温超声处理和干燥制得改性钛酸铈。
优选地，介孔钛酸铈、纳米玻璃纤维、偶联剂、聚甲基丙烯酸甲酯及聚乙烯醇的重量比为10-12：1-2：6-9：15-20：1-2。
优选地，偶联剂为钛酸酯偶联剂。
优选地，恒温温度为50-60℃，超声波功率为800-100W，处理时间为0.5-1h。
优选地，聚氨酯纤维为聚碳酸酯型聚氨酯纤维。
优选地，抗菌剂为天然有机抗菌剂和或有机高分子抗菌剂。
优选地，抗静电剂为非离子型抗静电剂，优选为乙氧基化脂肪族烷基胺。
优选地，抗氧剂为酚型抗氧剂，优选为抗氧剂BHT。
本发明以聚甲基丙烯酸甲酯和聚乙烯醇成膜物为壳，以介孔钛酸铈、纳米玻璃纤维为芯材，经偶联剂连耐磨性能接得到改性钛酸铈，与聚氨酯纤维的相容性好，可以显著提高聚氨酯纤维强度和抗撕裂性能；聚乙烯乙二醇蜡为增塑剂增加聚氨酯纤维的韧性，进一步提高抗撕裂性能；抗静电剂可出在聚乙烯中的抗静电性能，抗氧化剂有利于提高聚氨酯纤维的耐热稳定性及老化性能。本发明以聚氨酯纤维、改性钛酸铈、聚乙烯乙二醇蜡、抗菌剂、抗静电剂、抗氧剂为原料，合理控制各组分配比，得到医用无纺布材料的抗撕裂性能优异，抗菌、抗静电效果好。
