Description

一种耐潮湿环境的FIW完全绝缘线的绝缘漆
技术领域
本发明涉及FIW完全绝缘线技术领域,尤其涉及一种耐潮湿环境的FIW完全绝缘线的绝缘漆。
背景技术
现代电子技术迅速发展,数字电路的处理、传输进入高频化阶段,5G的来临,磁电产业要求越来越高,功率也越来越大;对于高耐压、高绝缘强度的高性能材料要求越来越高,并且要求对高性能材料的高耐压层越来越薄;其中导体以介电性能、耐热性、尺寸稳定性、耐湿性等几项性能尤为重要,而对于“外被”绝缘层来说:高绝缘性能、高耐压(≧20KV)、耐高潮湿(相对湿度68%~98%)、耐各种环境(酸、碱、高寒、耐盐等)等各种性能至关重要,必须与“高导体”要求匹配。而在磁电产业的原来材料漆包线(1500V)、三层绝缘线(6000V)远远无法满足其要求,且绝缘层太厚,使产品体积增大。
因此,现有技术存在缺陷,需要改进。
发明内容
本发明要解决的技术问题是:提供一种耐潮湿环境的FIW完全绝缘线的绝缘漆,在确保绝缘性能的同时,降低材料的厚度,综合提升FIW完全绝缘线的性能。
本发明的技术方案如下:提供一种耐潮湿环境的FIW完全绝缘线的绝缘漆,包括:树脂组分和溶剂组分,树脂组分与溶剂组分的质量比为1:1.7-4.3;
所述树脂组分按重量组分包括:
Figure BDA0002718163800000011
Figure BDA0002718163800000021
所述溶剂组分为:二甲基甲酰胺、二甲基乙酰胺、N-甲基吡咯烷酮、二甲基亚砜中的一种或至少两种的混合物。所述除湿剂为:聚酰亚胺溶液和纳米氯化钙。
树脂组分与溶剂组分混合后获得绝缘漆。
在绝缘漆中,聚氨酯漆包线漆被溶剂组分稀释,聚芳砜被溶剂组分溶解形成聚芳砜分子链,聚芳砜分子链穿插在聚氨酯漆包线漆中;聚四氟乙烯均匀分散在聚氨酯漆包线漆中,聚酰胺溶解于甲酚或苯酚中后,再通过溶剂组分均匀穿插在聚氨酯漆包线漆,聚酰亚胺溶液中的聚酰亚胺分子链均匀穿插在聚氨酯漆包线漆,纳米氯化钙均匀分散在绝缘漆中。
优选的,所述树脂组分按重量组分包括:

Figure BDA0002718163800000023
Figure BDA0002718163800000031
绝缘漆喷涂在衬底上,然后对喷涂在衬底上的绝缘漆进行烘烤,溶剂组分和苯酚或甲酚被蒸发掉,获得绝缘材料层,在绝缘材料层中,聚酰胺、聚芳砜、聚酰亚胺分子链穿插在绝缘材料层中,纳米氯化钙、聚四氟乙烯均匀分散在绝缘材料层中。
绝缘漆由于增加了聚酰胺、聚芳砜、聚四氟乙烯、聚酰亚胺、纳米氯化钙,在烘烤的过程中,绝缘漆中的溶剂组分会逐渐挥发掉,长链结构的聚酰亚胺、聚酰胺将会均匀伸入至绝缘材料层中,增加绝缘材料层的拉伸强度;聚芳砜分子链便会收缩,从而使得绝缘材料层更加致密,从而有效增强绝缘材料层的绝缘性能;纳米氯化钙、聚四氟乙烯均匀分散在绝缘材料层中,会被聚氨酯漆包线漆的分子链、聚酰亚胺分子链和聚芳砜的分子链缠绕,形成节点,从而使得绝缘材料层更加致密,可以进一步增强绝缘材料层的绝缘性能;因此,本发明获得的绝缘材料层可以在确保绝缘性能的同时,降低材料的厚度。进一步地,聚酰胺、聚芳砜、聚四氟乙烯、聚酰亚胺均具有优异的耐高温性能、耐酸碱腐蚀性能,可综合提升FIW完全绝缘线的性能。绝缘材料层中的聚酰亚胺材料是一种气密性材料,器可以充分避免水汽侵入内层。氯化钙是一种优异的干燥剂,即使绝缘材料层长期在潮湿环境下使用,使得部分水汽附着在绝缘材料层上,氯化钙也可以充分将水汽吸收,避免水汽侵入内层,满足三层绝缘线在潮湿环境下使用。
聚氨酯漆包线漆的型号为:deaweld S 193,所述聚酰胺为聚己内酰胺,纳米氯化钙、聚四氟乙烯的粒径为100nm-500nm。
采用上述方案,本发明提供一种耐潮湿环境的FIW完全绝缘线的绝缘漆,绝缘漆由于增加了聚酰胺、聚芳砜、聚四氟乙烯,长链结构的聚酰胺将会均匀伸入至绝缘材料层中,增加绝缘材料层的拉伸强度;聚芳砜分子链便会收缩,从而使得绝缘材料层更加致密,从而有效增强绝缘材料层的绝缘性能;聚四氟乙烯均匀分散在绝缘材料层中,会被聚氨酯漆包线漆的分子链和聚芳砜的分子链缠绕,形成节点,从而使得绝缘材料层更加致密,可以进一步增强绝缘材料层的绝缘性能;因此,本发明获得的绝缘材料层可以在确保绝缘性能的同时,降低材料的厚度。
