Description
技术领域
本发明涉及一种石墨烯导电面料,属于功能纺织品面料领域。
背景技术
户外服装面料通常由功能薄膜与纺织品通过粘结组分复合而成。由于户外服装多数由化学纤维制成,静电问题较为突出。静电的危害一般表现为衣服易起毛起球,易沾染灰尘污垢,贴近皮肤时有电击感和粘滞感等。抗静电面料一般是在织物中织入金属丝,将摩擦产生的静电及时传导散逸到外界去,但是这种导电面料柔软性不好。另一种方法是利用聚丙烯酸酯等具有吸湿作用的抗静电剂,在织物表面涂一层可以吸附水分子的化学薄膜,使织物表面形成一层连续的导电水膜,将静电传导逸散。
石墨烯是目前发现的最薄的二维材料,由六边形晶格组成,构成一个二维空间无限延伸的基面,其C-C键键长大约为0.142nm。石墨烯中每个中心碳原子的σ键与周围的其他碳原子连接,石墨烯具有优良的结构刚性。每个碳原子都有一个未成键的π电子,π电子在与平面垂直方向上形成了π轨道,电子可以在晶格中自由移动,所以石墨烯具有良好的导电性。
将石墨烯分散后均匀加入聚酯组分中,形成具有导电性能的聚酯薄膜,再以该薄膜与面料复合,则可解决户外复合面料的静电问题。
户外服装面料因户外环境中紫外线的存在,其面料中的染料易褪色,即面料的耐日晒牢度差,因此需在面料后整理时施加抗紫外线剂,改善面料的耐晒性能。
发明内容
本发明目的是提供一种导电面料,具体提供一种含石墨烯薄膜与表层面料复合形成的导电面料。
为实现上述目的,本发明采用了如下技术方案。
一种石墨烯导电面料,包括石墨烯薄膜、粘结层、表层面料以及在表层面料表面施加的防水层;
所述石墨烯导电面料的制备方法为:
a、防水剂与水配成30份/L的防水剂水溶液;
b、表层面料浸入防水剂水溶液,两浸两轧,轧液率70-90%;
c、90℃烘干、150℃焙烘,表层面料表面形成防水层;
d、在表层面料下表面涂覆粘结胶;
e、将石墨烯薄膜与表层面料涂覆有粘结胶的表面贴合;
f、100℃烘干、160℃焙烘,形成所述的石墨烯导电面料;
所述的防水剂,制备方法为:
1)将50份纳米硅溶胶加入搅拌容器中,加入400mL体积比为1:1的无水乙醇和超纯水的均匀混合液,超声分散0.5h;60℃时于搅拌状态下缓慢滴入0.9份硅烷偶联剂KH570及1.2份二苯甲酮基硅氧烷(如式1所示),再恒温搅拌24h,将产物注入离心管中高速离心分离,抽滤得到改性纳米硅溶胶;
2)将40份去离子水、1.8份十二烷基硫酸钠(SDS)和壬基酚聚氧乙烯醚(OP-10)(质量比为2∶1)加入到搅拌器中,溶解均匀后,在30min内匀速滴加12份有机硅聚合单体(如式2所示)、8份有机氟单体,滴加完毕后,用磁力搅拌器以1500rpm/min的速度搅拌30min,制得预乳化液;
3)在装有搅拌器、回流冷凝管、温度计的反应器中加入120份水、30份改性硅溶胶、3.2份十二烷基硫酸钠(SDS)和壬基酚聚氧乙烯醚(OP-10)(质量比为2∶1),搅拌均匀后升温至75℃,然后在2h内同时滴加预乳化液和引发剂水溶液(0.3份引发剂与10份水),滴完后保温30min,再升温至85℃、保温2h;冷却降温至40℃以下,用氨水将乳液的pH值调至7,得到所述防水剂乳液。
所述的二苯甲酮基硅氧烷,其制备方法为:a、在氮气保护下,按摩尔比1.02:1,将3-异氰酸酯基丙基三甲氧基硅烷、2-羟基-4-甲氧基二苯甲酮加入至反应器中,加入占3-异氰酸酯基丙基三甲氧基硅烷质量0.5%的辛酸亚锡,在70℃下搅拌反应5h,得二苯甲酮基硅氧烷(如式1所示)。
所述的有机硅聚合单体,由2-(三甲基硅氧基)乙醇胺与甲基丙烯酸异氰酸酯乙酯反应制成,其方法如下:
在装有搅拌器、温度计、冷凝管的反应器中,加入经脱水处理的2-(三甲基硅氧基)乙醇胺、甲基丙烯酸异氰酸酯乙酯、二月桂酸二丁基锡,100℃搅拌反应5h,得含C=C键的功能性有机硅聚合单体(如式2所示);2-(三甲基硅氧基)乙醇胺、甲基丙烯酸异氰酸酯乙酯的摩尔比1:1,二月桂酸二丁基锡的质量占反应单体总质量的0.4%。
所述的石墨烯薄膜,厚度为0.02mm。
所述的表层面料为涤纶双层面料,含90%涤纶、10%氨纶,面料规格为75D+40D*75D+40D/150D+40D,克重260g/m2。
所述的粘结胶由增稠剂、粘合剂、交联剂组成,各组分质量比为1:100:0.5。
所述的增稠剂为聚丙烯酸。
所述的粘合剂为丙烯酸酯乳液。
所述的交联剂为封闭型异氰酸酯交联剂。
所述的有机氟单体为甲基丙烯酸三氟乙酯、丙烯酸三氟乙酯、甲基丙烯酸六氟丁酯中的一种。
本发明石墨烯导电面料由表层面料和石墨烯薄膜复合而成,表层面料设有疏水层,赋予本发明所述面料良好的疏水及导电性能。
将紫外吸收单体引入有机硅聚合物中,使防水剂兼具防水、抗紫外线功能,可提高表层面料的耐日晒牢度。
防水剂采用有机—无机复合材料来制作低表面能材料,即通过有机材料来降低表面能,无机材料来构造微小凹凸结构,利用两者共同作用来生产效果更好的超疏水效果。
对面料做防水、抗紫外线功能整理时,因防水剂与抗紫外线剂表面性能的差异,往往对这两种整理分别进行。本发明防水剂结合了抗紫外单体,实现了一剂复合多种功能,一次整理即可实现多种功能,缩短了加工工艺流程。
具体实施方式
本发明中所述物质的单位“份”指的是“质量份”。

所述的有机氟单体为甲基丙烯酸三氟乙酯、丙烯酸三氟乙酯、甲基丙烯酸六氟丁酯中的一种。
所述的有机硅聚合单体,由2-(三甲基硅氧基)乙醇胺与甲基丙烯酸异氰酸酯乙酯反应制成,其方法如下:
在装有搅拌器、温度计、冷凝管的反应器中,加入经脱水处理的2-(三甲基硅氧基)乙醇胺、甲基丙烯酸异氰酸酯乙酯、二月桂酸二丁基锡,100℃搅拌反应5h,得含C=C键的功能性有机硅聚合单体;2-(三甲基硅氧基)乙醇胺、甲基丙烯酸异氰酸酯乙酯的摩尔比1:1,二月桂酸二丁基锡的质量占反应单体总质量的0.4%。所涉反应过程如(1)所示。
其中,2-(三甲基硅氧基)乙醇胺的制备方法为:在带有机械搅拌、温度计的反应器中,投入乙醇胺,搅拌滴加六甲基二硅氮烷,于5~50℃反应0.5~2h,反应完毕,经减压抽滤得2-(三甲基硅氧基)乙醇胺。乙醇胺与六甲基二硅氮烷的摩尔比为2:1。
纳米硅溶胶改性时使用的所述二苯甲酮基硅氧烷,由2-羟基-4-甲氧基二苯甲酮与3-异氰酸酯基丙基三甲氧基硅烷制成,方法如下:在氮气保护下,按摩尔比1.02:1,将3-异氰酸酯基丙基三甲氧基硅烷、2-羟基-4-甲氧基二苯甲酮加入至反应器中,加入占3-异氰酸酯基丙基三甲氧基硅烷质量0.5%的辛酸亚锡,在70℃下搅拌反应5h,得二苯甲酮基硅氧烷。所涉反应过程如(2)所示。
乙烯基硅氧烷偶联剂,由于含有可水解基团Si-O-C,在乳液聚合过程中,即使采取延迟滴加、添加水解抑制剂等措施,仍会发生一定程度的水解、缩合、聚合物分子间过度交联而导致聚合反应失稳。本发明防水剂采用了-Si(CH3)3基团的有机硅聚合单体,由于其空间位阻大、不水解,大大提高了乳液聚合的稳定性,使有机硅在聚合物分子链中的分布更均衡,有效增强聚合物的拒水性能。
有机氟化合物的C-F键长短,键能高,氟原子半径较小,从而使其分子内部结构非常紧密,紧密缠绕着C-C主链,对其主链具有屏蔽保护作用,使氟具有相对较低表面能,与具有较低表面张力的硅氧烷共聚,可赋予织物低表面张力、较为突出的疏水性和耐久性,还可让处理后的织物保持本身的柔软性和透气性。
所述的石墨烯薄膜,厚度为0.02mm。
所述的表层面料为涤纶双层面料,含90%涤纶、10%氨纶,面料规格为75D+40D*75D+40D/150D+40D,克重260g/m2。
