Description
技术领域
本发明涉及无纺布技术领域,尤其涉及一种擦拭纸用改性无纺布的制备方法。
背景技术
擦拭纸采用长纤木浆或无纺布材料制成,经济、卫生、品质稳定、库存不占空间、吸收力强、不伤物体表面、不掉毛屑、无静电产生,目前已被广泛应用在食品、制药、家庭清洁等领域。涤纶无纺布具有成本低、重量轻、耐腐蚀、力学性能及化学稳定性好等优点,目前已成为擦拭纸常用的材料之一,但是涤纶纤维的疏水性强,且不具有抗菌性,用其制成的擦拭纸亲水性差,抗菌性不是很好,限制了应用。
发明内容
基于背景技术存在的技术问题,本发明提出了一种擦拭纸用改性无纺布的制备方法,其过程简单,得到的无纺布亲水性和抗菌性好,用其制成的擦拭纸吸水性好,抗菌性能优异,且不掉毛屑,发尘性低。
本发明提出的一种擦拭纸用改性无纺布的制备方法,包括以下步骤:
S1、将纳米氧化锌加入乙醇中,分散均匀后加入硅烷偶联剂KH-560,在45-60℃下搅拌50-80min,过滤、洗涤、干燥得到物料A;将物料A冷冻干燥后加入二甲基甲酰胺中,超声分散后加入巯基丁二酸和无水三乙胺,在30-38℃下搅拌反应10-20h,经过滤、清洗、干燥得到物料B;将物料B加入二甲基甲酰胺中,超声分散后加入姜黄素和对甲苯磺酸,在55-65℃下搅拌反应4-10h,清洗、干燥得到改性纳米氧化锌;
S2、将十二烷基苯磺酸钠、十二烷基硫酸钠、吐温-80和磷酸钠加入水中,加入改性纳米氧化锌搅拌均匀得到浸渍液;将涤纶无纺布浸渍于浸渍液中,浸渍45-55min,烘干后得到浸渍无纺布;

本发明所述擦拭纸用改性无纺布的制备方法中,首先以硅烷偶联剂KH-560为改性剂对纳米氧化锌进行了改性,将环氧基团引入到了纳米氧化锌的表面,得到了物料A,之后将物料A与巯基丁二酸混合,在无水三乙胺的作用下,物料A中的环氧基团与巯基丁二酸中的巯基发生了反应,从而将羧酸引入到了纳米氧化锌的表面,提高了纳米氧化锌的羧基含量,与姜黄素混合后,纳米氧化锌表面的羧基能与姜黄素中的羟基发生酯化反应,从而将姜黄素引入到了纳米氧化锌的表面,得到了改性纳米氧化锌,以改性纳米氧化锌、十二烷基苯磺酸钠、十二烷基硫酸钠、吐温-80和磷酸钠为原料对涤纶无纺布进行浸渍,将改性纳米氧化锌、十二烷基苯磺酸钠、十二烷基硫酸钠、吐温-80和磷酸钠吸附在了涤纶无纺布的表面,保持了涤纶无纺布的性质,避免了涤纶无纺布的强力损失,同时一方面,十二烷基苯磺酸钠、十二烷基硫酸钠、吐温-80中的长链疏水结构能与涤纶无纺布结合,另一端极性亲水基团则伸向空气更易与水分子亲近,形成定向排列的吸附层,裸露在涤纶无纺布的表面,有效地改变了原涤纶无纺布表面的润湿性能,降低了其表面张力,具有润湿作用,一方面,磷酸钠分子具有对金属离子的螯合作用和提高胶溶、乳化和分散的作用,可以降低水中钙离子、镁离子的干扰,消除不利影响,多方面的作用显著改善了涤纶无纺布的亲水性,使所得擦拭纸具有优异的吸水性能,同时因引入了改性纳米氧化锌,其中的纳米氧化锌、姜黄素具有协同作用,赋予涤纶无纺布优异的抗菌性能,使得到的浸渍无纺布具有亲水、抗菌性;之后以丙烯酸树脂、丙烯酸羟乙酯、丙烯酸十八酯为原料,通过紫外光固化反应,在浸渍无纺布的表面形成了交联产物,牢固的吸附在涤纶无纺布的表面,且不易脱落,在保持涤纶无纺布性能的前提下进一步提高了涤纶无纺布的亲水性,降低了表面接触角,增大了纯水通量,且亲水持久稳定。
将本发明所述擦拭纸用改性无纺布的制备方法制备的无纺布制成擦拭纸,对其进行性能检测,其吸水性为32-45mm/100s。
