Description
技术领域
本发明涉及无纺布,具体涉及一种高耐裂无纺布。
背景技术
手术衣根据使用情况主要分为重复性使用手术衣和一次性手术衣。重复使用手术衣主要选用材质为普通棉织物、高密度聚酯纤维织物及PE、TPU、PTFE多层贴合膜复合手术衣。一次性手术衣主要为SMS\SMMS手术衣为主,SMS或SMMS无纺布手术衣,加强片为无纺布复合材料。
现有的无纺布手术衣的耐裂性能不高,不能满足市场的需求。
发明内容
基于背景技术存在的技术问题,本发明提出了一种高耐裂无纺布。本发明具有优异的耐裂性能。
本发明提出的一种高耐裂无纺布,其原料按重量份包括:黄麻纤维37-50份、聚醋酸乙烯树脂24-35份、椰壳纤维8.5-13份、温石棉21.5-25.5份、玉米纤维2-8份、海藻提取物3-7.5份、粘合剂2.5-5份、硅油1-4份、阻燃剂1.5-3份。
优选地,所述聚醋酸乙烯树脂为改性聚醋酸乙烯树脂,所述改性聚醋酸乙烯树脂的制备方法为:将碳纳米管、纳米硅、硅灰石纤维与聚醋酸乙烯树脂混合均匀,进行剪切搅拌,得到改性聚醋酸乙烯树脂。
优选地,所述剪切搅拌的温度为160-180℃。
优选地,所述剪切搅拌的时间为1-1.5h。
优选地,所述剪切搅拌的速度为4000-5000r/min。
优选地,所述海藻提取物的质量分数为50-75wt%。
优选地,所述阻燃剂为纳米阻燃剂。
本发明可按照常规方法进行制备。
本发明的原料包括:黄麻纤维、聚醋酸乙烯树脂、椰壳纤维、温石棉、玉米纤维、海藻提取物、粘合剂、硅油、阻燃剂,且在优选方案中,在高温剪切的作用下,采用碳纳米管、纳米硅、硅灰石纤维对聚醋酸乙烯树脂进行复合改性,随着温度的升高,碳纳米管形成拉伸方向的纤维,与硅灰石纤维逐渐在聚醋酸乙烯树脂内部形成紧密的交联网络结构,并以桥接方式抑制裂缝扩展,延长本发明的疲劳寿命,而纳米硅与聚醋酸乙烯树脂在网络层间分布,两者具有协效作用,能够进一步提高其抗剪切强度,同时纳米硅分散于聚醋酸乙烯树脂中具有增黏作用,能够降低本发明的拉伸延展性,进一步提高本发明的抗裂性。本发明中添加黄麻纤维、椰壳纤维与聚醋酸乙烯树脂配合,能够进一步优化本发明的耐裂性能,同时增强本发明的韧性;添加温石棉与硅油配合作用,能够提高本发明的保温和透气性能;添加海藻提取物与玉米纤维配合作用,能够提升本发明的抗菌性能。
