Description

一种纳米远红外碳纤维发热片
技术领域
本发明属于纳米远红外碳纤维发热技术领域，特别涉及一种纳米远红外碳纤维发热片。
背景技术
碳纤维（Carbonfiber）由碳元素构成的无机纤维，纤维的碳含量大于90%，它不仅具有碳材料的固有本征特性，又兼具纺织纤维的柔软可加工性，是新一代增强纤维，发热时产生对人体健康极为有益的远红外线热辐射（约765.9W/M，相当于一部频谱理疗仪），其电热转换率达95%以上，比镍铬、钨钼等材料作为发热体节能30%；而且，被人体、衣物等直接吸收性特强，在热传递过程中热量损失小，碳纤维还具有高强度、高模量、耐高温、抗疲劳、耐腐蚀、防水、抗蠕变等诸多特点。
碳纤维发热片是一种发明的高能纤维材料，它是碳纤维经过加工后而形成的一种片状体，可以在短时间内迅速加热，具有迅速升温的功效，被广泛用于加热毯、加热坐垫、加热鞋垫等的加热***。
公告号CN103079297A的中国专利，公开了一种碳纤维加热片及其制备方法，其是在下绝缘包覆层上布碳纤维丝形成网状结构的碳纤维层，在碳纤维层的两端压合电极条并铺覆上绝缘层，粘合处理后，在电极条对应的两端焊接电极引线，然而，在此过程中，需在上下绝缘包覆层上涂覆热熔胶，黄铜网退火处理后双面涂覆热熔胶，粘合处理并切条，还需配合模具进行碳纤维层的成型，此制备方法实际操作较为复杂，需要的材料和设备较多，限制了生产时间，生产成本亦偏高。
我司上一份发明专利：201410844887.2公开了一种碳纤维发热片的制作方法，但采用的高绝缘性的棉线或涤纶线，并且导电发热体的边缘没有导电装置连接，并且无防水功能，有导电发热体松动及静电产生打火的安全隐患，并且人体的汗水浸透到导电发热体上面，避免了被汗水腐蚀的安全隐患；提高了发热片的使用寿命及使用安全。
