Flexible calcium lanthanum chromate/silicon oxide composite fiber material with high infrared emissivity as well as preparation method and application of flexible calcium lanthanum chromate/silicon oxide composite fiber material
The invention relates to a high-infrared-emissivity flexible calcium lanthanum chromate/silicon oxide composite fiber material and a preparation method and application thereof.The high-infrared-emissivity flexible calcium lanthanum chromate/silicon oxide composite fiber material is prepared through the following preparation method: (1) dissolving a silicon source and a chelating agent in a solvent A to obtain an inorganic precursor solution A, and then adding a spinning aid polymer to obtain a silicon oxide spinning solution; (2) dissolving a chromium source, a lanthanum source and a calcium source in a solvent B to obtain an inorganic precursor solution B, and then adding a spinning aid polymer to obtain a calcium lanthanum chromate spinning solution; (3) respectively putting the silicon oxide spinning solution and the calcium lanthanum chromate spinning solution into mutually independent spinning propulsion devices, and spinning on the same receiving roller to obtain composite gel nanofibers; and (4) drying and calcining the obtained composite gel nanofiber to obtain a target product. Compared with the prior art, the infrared emissivity of the composite fiber material is larger than 80%, and the composite fiber material can be independently used, and is good in flexibility, excellent in strength, easy to recycle and simple in preparation method.
本发明涉及一种高红外发射率柔性铬酸钙镧/氧化硅复合纤维材料及其制备方法与应用，该材料由以下制备方法制得：(1)取硅源、螯合剂溶解于溶剂A中，得到无机前驱体溶液A，然后加入助纺聚合物，得到氧化硅纺丝溶液；(2)取铬源、镧源和钙源溶解于溶剂B中，得到无机前驱体溶液B，然后加入助纺聚合物，得到铬酸钙镧纺丝溶液；(3)将氧化硅纺丝溶液、铬酸钙镧纺丝溶液分别放在相互独立的纺丝推进装置中且在同一接收滚筒上进行纺丝，得到复合凝胶纳米纤维；(4)所得复合凝胶纳米纤维经干燥、煅烧得到目的产物。与现有技术相比，本发明复合纤维材料红外发射率＞80％，可单独使用，柔性好，强力佳，易回收，制备方法较简单。
