High-resistance crucible for graphitization of lithium battery negative electrode material and preparation process of high-resistance crucible
The invention relates to the field of crucibles, in particular to a high-resistance crucible for graphitization of a lithium battery negative electrode material and a preparation process thereof.The preparation process comprises the steps that hydroxyl-terminated polydimethylsiloxane and isophorone diisocyanate serve as raw materials, an isocyanate-terminated prepolymer is synthesized under the catalysis of a catalyst dibutyltin dilaurate, adipic acid dihydrazide, 4, 4 ', 5'-tetramethyl-1, 3, 5-trimethyl-1, 3, 5-trimethyl-1, 3, 5-trimethyl-1, 3, 5-trimethyl-1, 3, 5-trimethyl-1, 3, 5-trimethyl-1 The preparation method comprises the following steps: synthesizing an organic silicon polyurethane prepolymer by using 4, 4 '-diaminodiphenyl disulfide as a chain extender, and further performing in-situ polymerization and compound modification on the organic silicon polyurethane prepolymer, the composite basalt fiber and polyhedral oligomeric alcohol to prepare the modified asphalt. The preparation method comprises the following steps: preparing polyhydroxy polyhedral oligomeric alcohol from polycaprolactone triol, polycaprolactone tetraol and dicyclohexylmethane diisocyanate; a zirconium-titanium bimetal organic framework with terephthalic acid as an organic ligand grows on the surface of the activated basalt fiber layer by layer by adopting a layer-by-layer self-assembly method, and modification treatment is performed by using polyhedral oligomeric alcohol to obtain the composite basalt fiber.
本发明涉及坩埚领域，具体是一种锂电池负极材料石墨化用高耐坩埚及其制备工艺，先以羟基封端的聚二甲基硅氧烷、异佛尔酮二异氰酸酯为原料，在催化剂二月桂酸二丁基锡催化下合成异氰酸酯封端预聚体，以己二酸二酰肼、4,4'‑二氨基二苯二硫醚为扩链剂合成有机硅聚氨酯预聚体，然后进一步与复合玄武岩纤维、笼状多元醇一起以原位聚合，复合改性制备了改质沥青；用聚己内酯三醇、聚己内酯四醇、二环己基甲烷二异氰酸酯制备多羟基的笼状多元醇；采用层层自组装法在活化玄武岩纤维表面逐层生长以对苯二甲酸为有机配体的锆钛双金属有机骨架，并用笼状多元醇进行改性处理，得到复合玄武岩纤维。
