Description
技术领域
本发明涉及纺织品用防水剂领域,IPC分类号为D06M15/17,具体涉及一种军用纺织面料专用防水剂及其制备方法。
背景技术
随着现代军事的发展,士兵在开展军事演练、军事维和、公共事件安全保障等活动时,需携带各种作战装备及防护用品,在极端环境条件下,要求所携带防护用品必须具有高强度及高耐用性能,如何提高军服的军需防护性能来保障军用防护用品在严酷复杂条件下具备较高的可靠性,已成为适应现代战争军需保障发展的重要问题。
军用纺织面料对于我国军队的发展起着重要的作用,它不仅被应用于军装和军被,也可以被应用在军用常服、礼服、普通工作服等衣服。军队防护服在极端天气及环境下具有优异的性能如轻薄、耐磨、防水性好对于保障士兵安全是非常重要的。
专利CN201721617152.1公开了一种新型高性能纺织防水面料,由基布层、防水面料层,防辐射层、绒布内层组成,制备了面料立体感强、具有较好抗辐射性能及防水性能的新型防水面料,然而其防水层采用聚酯纤维织造,透气性差,其具有一定的防水性,但防水性能较差,且此防水纺织面料由多层结构粘附组成,防水性的纺织面料的重量较重,极大降低了人们的穿着舒适感。专利CN201910691791公布了一种抗菌防水纺织品的制作方法,将防水剂混合在纺织面料甲壳素纤维内部制备了防水效果较好具有一定抗菌性的防水纺织品,但其纺织品耐磨性较差。
发明内容
为了解决上述问题,本发明的第一方面提供了一种军用纺织面料专用防水剂,所含原料及各原料的重量份:硅树脂50-80份、硅油20-30份、纤维素醚2-10份、偶联剂1-5份、填充剂0.5-3份、溶剂适量。
作为一种优选的技术方案,所述硅树脂选自MT型硅树脂、MQ型硅树脂、DT型硅树脂中的一种;
作为一种优选的技术方案,所述MQ型硅树脂包括分子式为[(R)3SiO1/2]M[SiO4/2]Q类聚合物中的一种,MQ值是MQ型硅树脂中单官能度硅氧烷封闭链节(M)与四官能度硅氧烷链节(Q)的物质的量比值,该比值可以反映硅树脂的整体结构和分子量的大小,有机基团R增加其与其他组分的相容性起增粘作用,SiO4/2链节提高复合材料的强度起补强作用。有机基团R的差异决定MQ型硅树脂的类型,R为甲基时,称为甲基MQ硅树脂,MQ比值为0.5-0.8:1,对于甲基MQ硅树脂而言,MQ值比例较小时其补强效果较好;部分R为乙烯基时,称为甲基乙烯基MQ硅树脂;部分R为氢时,称为甲基氢MQ硅树脂;此外,MQ型硅树脂还包括甲基苯基MQ硅树脂、乙烯基MQ硅树脂、苯基MQ硅树脂、含氟MQ硅树脂、MDQ硅树脂、MTQ硅树脂;
作为一种优选的技术方案,所述硅油选自甲基硅油、乙基硅油、苯基硅油、甲基含氢硅油、甲基苯基硅油、甲基氯苯基硅油、甲基乙氧基硅油、甲基三氟丙基硅油、甲基乙烯基硅油、甲基羟基硅油、乙基含氢硅油、羟基含氢硅油、含氰硅油中的一种;
作为一种优选的技术方案,所述纤维素醚包括非离子纤维素醚、阴离子纤维素醚、阳离子纤维素醚中的一种;
作为一种优选的技术方案,所述非离子纤维素醚选自甲基纤维素、甲基羟乙基纤维素、甲基羟丙基纤维素、羟乙基纤维素、氰乙基纤维素、羟丁基纤维素中的一种;
作为一种优选的技术方案,所述偶联剂包括无机偶联剂、有机硅类偶联剂、有机磷类偶联剂、铝类偶联剂中的一种;

本发明的第二方面提供了一种军用纺织面料专用防水剂的制备方法,包括以下步骤:
(1)将硅树脂、硅油、溶剂置入容器搅拌得混合物a;
(2)向混合物a中加入纤维素醚搅拌得混合物b;
(3)在混合物b溶液中加入偶联剂及填充剂,搅拌得到一种军用纺织面料专用防水剂。
有益效果
(1)通过对硅树脂、硅油、溶剂、纤维素醚、偶联剂、填充剂进行混合,制备得到一种防水性能优异的军用纺织面料专用防水剂,其具有轻薄,耐磨、抗菌等优异性能。
(2)MQ硅树脂耐候性好,防水性好且阻燃性好,尤其是MQ硅树脂为甲基MQ硅树脂,MQ比值为0.5-0.8:1时,具有优异的防水性及阻燃性,且具有优异的耐候性,可在-60℃至+300℃温度环境下使用,使军用纺织成衣在恶劣环境下仍能保持优异性能。其原因可能是,甲基MQ硅树脂,MQ值比例适当时其补强效果较好,具有优异的硬度及拉伸强度。甲基MQ硅树脂与溶液中其他活性成分发生反应,在纺织面料表面形成一层防水膜,使水与纺织面料表面接触角增大,降低纺织面料表面张力,且甲基MQ硅树脂在高温下其二维Si-O-Si链状结构会转变为三维网状结构,在纺织面料表面形成光滑紧密的硬质壳层,具有优异的隔热效果,阻止纺织面料内其它高分子材料热分解产物扩散到燃烧区。
(3)本发明通过加入石墨烯,使得军用纺织面料具有抗菌性、防水性及抗静电性。尤其是石墨烯为单层氧化石墨烯时,军用纺织面料具有优异的抗菌性、防水性及抗静电性,其原因可能是单层氧化石墨烯由单层碳原子紧密堆积为二维蜂窝状晶体,具有片状结构且边缘锋利,可对细菌进行物理切割,破坏细菌细胞壁,使其电解质泄漏,此外,氧化石墨烯还可抽取细菌细胞膜上磷脂分子,破坏细菌细胞膜。氧单层氧化石墨烯与其他成分相互协同降低了纺织面料表面能,增大了纺织面料与水的接触角,产生反毛细管现象。此外,氧化石墨烯与氢氧化铝混合后,在纺织面料表面能形成均匀致密的导电层。
(4)石墨烯为碳元素排布致密的平面二维结构,具有高强度、高模量、高硬度和低摩擦系数等特点,尤其是石墨烯为单层氧化石墨烯其与氢氧化铝复配后,其中氢氧化铝与氧化石墨烯质量比为2-3:1,二者的协同作用使军用纺织面料具有优异的耐磨、轻薄等性能。其原因可能是氧化石墨烯/氢氧化铝复合物通过原子间共价键相连,形成网络状结构,键合力优异,具有高强度、高韧性、低摩擦系数等特点。
(5)本发明进一步向硅树脂、硅油、溶剂混合物中加入纤维素醚搅拌,并将所得混合物再次与偶联剂及填充剂进行混合,制备得到一种防水性能优异的军用纺织面料专用防水剂,其具有轻薄,耐磨、抗菌等优异性能。
