Abstract
本发明涉及一种远红外加热材料，由以下组分按以下重量份制备而成：AlCl3·6H2O 25‑35份，MgCl2 4‑7份，ZrOCl2·8H2O 10‑20份，TiCl4 20‑30份，SiCl4 15‑30份，PdCl2 0.2‑0.3份，LaCl3 1.4‑3.2份。本发明远红外加热材料的远红外陶瓷粉通过外加少量稀土氧化物氧化镧和微量贵金属氧化物氧化钯，提高了远红外陶瓷粉体材料晶格振动活性，且具有激活催化作用，尤其是采取特定重量比的氧化镧和氧化钯，可显著提高远红外陶瓷粉体的辐射率，配合其他远红外材料使用效果更佳。本发明的远红外陶瓷粉材料可用于远红外纺织衣物等家用理疗领域。
Description
技术领域
本发明属于红外辐射材料领域，特别涉及一种远红外加热材料及其组合物。
背景技术
红外辐射与可见光、紫外线、X 射线、γ射线、微波、无线电波等一起构成了整个无限连续的电磁波谱。红外辐射的波长通常为0.76 -1000 μm，一般将波长为3 -100 μm 称为远红外。具有远红外辐射性能的陶瓷粉体材料称为远红外陶瓷粉。
远红外陶瓷粉主要有低温应用型和高温应用型。高温区主要应用于锅炉的加热，烤漆，木材、食品的加热和干燥等，在常温区主要应用于制造各种远红外保暖材料。
低温型远红外陶瓷粉又称常温型远红外陶瓷粉，是MgO-Al2O3-TiO2-ZrO2系的白色陶瓷粉体，其具有光热转换效率高、无需热源、可吸收环境热量后以远红外能量形式输出的特点，是一种新型光热转换功能陶瓷材料。低温型远红外陶瓷粉用途广泛，采用掺入和涂覆的方法，可应用于塑料、纺织、造纸、服装、医疗器械和陶瓷等方面。把远红外陶瓷粉掺入塑料母粒中可以制成保鲜盒，还可以做成塑料膜，用于农作物地膜或保鲜袋等。由于在室温附近（20～50℃）能辐射出3～15μm 波长的远红外线，由于此波段与人体红外吸收谱匹配完美，被称为“生命热线”或“生理热线”。因此，把远红外陶瓷粉掺入到纺织纤维中，制成的织物在人体正常温度下自动调节吸取人体周围和自身的辐射能量，发射出对人体有益的远红外线，激发人体组织细胞的活力，改善微循环，促进新陈代谢，消除疲劳，实现人体保健作用。另外，把远红外陶瓷粉制成远红外陶瓷球，不仅可用于汽车节油系统，还可以减少汽车尾气等有害气体的排放，减少环境污染。
通常制备远红外陶瓷粉料的方法有液相沉淀法和固相合成法两种，液相沉淀法的工艺步骤包括：配料-活性剂溶解-沉淀-过滤水洗-脱水-干燥-煅烧-粉碎-性能检测-备用。固相合成法工艺步骤包括：配料-球磨混合-高温合成-磨细-过筛-性能检测-备用。
作为远红外陶瓷材料而言，根据使用条件的不同，对其性能要求也各有差异，但发射率始终是衡量优质远红外陶瓷材料最重要的性能指标。因此，在远红外陶瓷材料领域，如何获得具有理想高辐射率的远红外陶瓷粉体是始终被关注的重点问题。
现代人生活节奏的加快以及智能手机的普及造成众多不良习惯，导致人们腰颈椎疼痛病高发，各种慢性疾病及亚健康人群数量急增，且有从传统老年化向青年化发展的趋势。目前主要的治疗途径为医院治疗和家庭治疗。其中，家庭治疗的几个主要方法为：内服非留体抗炎药，外用凝胶剂、贴膏以及加热产品以达到短暂缓解。内服药长期使用造成其他组织器官的伤害，副作用大；外用贴膏又因与人体直接接触，易致皮肤过敏、灼伤、疗效时间短、换药频次高；加热产品则功效单一，不能综合性解决各种临床症状。因此在腰颈椎疼痛病领域亟需一种具有治疗和保健功效的家庭理疗方案。
