Description
本发明涉及日常电热取暖保温生活用品的电热部件的制造方法,特别是在柔性材料的生活用品上的电热膜发热体的制造方法。
目前,人们所使用的电热取暖保温的日常生活用品通常是以金属电热丝为发热体,而金属发热丝作为电发热体除了其热效率低、耗能大,易于氧化、绝缘性能差、使用寿命短外,按现有科学及工业技术来说,这种金属电热丝发热体的应用范围还受到一定的限制。所以人们又发明了电热膜发热体,随即应用研究使其形成了一批新的日常生活电器用品上市,这些电热膜的产品其基体材料多是金属硬体材料,其固着加工及焊接引出线均较方便,其热效率高、耗能少、不易氧化、绝缘安全性好。但随着人们需要的提高,极需有一批柔软基材上的电热膜的产品问世,但由于电热膜的不可屈折的脆性,以及固着方法,特别是导线与发热电热膜会受使用温度及覆盖塑料松驰变形导致固定接触不良,会影响日后使用中不能保证电热膜的正常工作,且还影响到使用寿命。
本发明的目的是提供一种柔性电热膜发热体的制造方法,其制成的电热膜发热体固着在柔软基体材料上,可弯折,可在一定范围内拉长,可以将电极导线牢固的与电热膜层相固定,使用寿命长、绝缘安全性好。
本发明的技术解决方案是这样的,
一种柔性电热膜发热体的制造方法,其步骤为:
A、先在高分子柔性基体材料聚氨酯、氟橡胶、三元乙丙橡胶皮革的任一种表面上按所需各种图案形状涂上含量50%以上的银浆,经100至130℃,5至25分钟烘烤,或自然晾干,形成银浆导电极,此时银浆含量达96%以上,可在电极上焊接导线作引出线。
B、再将胶体石墨粉85.47%,水溶性醇酸树脂氰氨基漆8.55%,三氧化二锑粉5.13%,以及氧化铅、二氧化锰、三氧化二铁的任一种或几种的金属化合物0.85%配制成均匀浆体的石墨浆按所需图案形状块涂复在基体材料表面及金属电极上制成电热膜。
C、尔后在有电热膜的基体材料表面可通过浇注或压贴的方法固定上绝缘保护层。
以上所述的银浆的组成是银粉及松节油。
本发明所述的电热膜的厚度为10至300微米。
以上本发明在电热膜的基体材料表面固定绝缘保护层的方法,可采用将高分子预聚体与固化剂混合浇注覆盖在有电热膜的基体材料表面上进行硫化或室温固化,而形成结合牢固的绝缘密封保护层,或者是按形状、尺寸预制好的高分子片材绝缘保护层,涂上橡胶胶粘剂后压贴在电热膜的基体材料表面,形成结合牢固的绝缘保护层。
本发明的优点是电热膜发热体固着在柔软基体材料上,可弯折,可在一定范围内拉长,可以将导线牢固的固定在电热膜层上,使用寿命长,绝缘安全性好。
下面对本发明的实施例进行描述:
图1本发明的方法涂成的银浆导电极及电热膜形状示意图。
实施例一:
选用已加工成所需形状、尺寸的柔软性的2毫米厚的聚氨酯基体材料,用乙醇擦洗干净,自然干燥。用银粉100,松节油80(重量份数)调配成均匀的银浆,用刷涂的方法在基体材料适当的部位刷银浆,如图1所示,放于120℃烘箱中恒温15分钟,待其成膜干燥后便形成含金属银96%以上的银浆导电极,其厚度可为50至200微米。在电极上可选任一点焊接电极引出线,用重量份数的胶体石墨粉100份,水溶性醇酸树脂氰氨基漆10份,三氧化二锑粉6份,氧化铅1份配制搅匀成胶体石墨浆体,将胶体石墨浆体按图1的形状刷涂在有电极的基体材料表面,刷涂覆盖层两端与电极部分连接,覆盖层可为10至300微米内任一需要厚度。自然干燥。将聚氨酯预聚体与传统使用的固化剂混合后浇注在有电热膜的基体材料及电极上表面,覆盖住电极及电热膜,其厚度可为0.1至3毫米的所需厚度,在120℃±5℃的硫化机上硫化,压力为1-3MP/cm2,时间为10至20分钟,便形成绝缘保护层,即完成了柔性电热膜发热体的制备,其柔性电热膜发热体的功率可在0.1至15W/cm2,电压在3~24V,并可同时安装继电控制器来控制温度。
实施例二:
同实施例一,只是柔性的基体材料选用三元乙丙橡胶,涂电极的方法采用80目丝网印刷,可控制涂层厚度均匀一致,自然干燥,在电热膜材质的胶体石墨浆中,金属化合物除氧化铅外,还可同时加入适量的三氧化二铁一起使用。覆盖了绝缘保护层后,最好在室温固化。
实施例三:
同实施例一,只是基体材料选择为皮革,以及绝缘保护层是选用已按形状、尺寸预制好的皮革片材通过胶粘剂压贴在基体材料上,即完成了柔性电膜发热体的制备。
