摘　　要：探讨了不同种类炭黑、超分散剂的选择及用量对炭黑色浆分散稳定性的影响,优化了炭黑色浆的工艺配方,并对色浆的可纺性进行验证,分析了炭黑粒子在纤维中的粒径大小、分散状态和相容性。结果表明:以质量分数为10%的4#炭黑和质量分数为20%的超分散剂A所制备出的炭黑色浆具有良好的耐热贮存稳定性,颜料粒子尺寸可达到纳米级别,且与超高分子质量聚乙烯(UHMWPE)纺丝原液相容性好;该色浆适用于原液着色UHMWPE纤维的生产。The influence of the selection and dosage of different types of carbon black and hyperdispersant on the dispersion stability of carbon black color slurry was discussed.The process formula of carbon black color paste was optimized,and the spinnability of the color paste was verified.The particle size,dispersion state and compatibility of carbon black particles in fiber were analyzed.The results show that the carbon black paste prepared with the mass fraction of 10%4#carbon black and the mass fraction of 20%hyperdispersant A has good heat resistance and storage stability,the pigment particle size can reach nanometer level,and the compatibility with the ultra-high molecular weight polyethylene(UHMWPE)spinning stock is good.The color slurry can be applied to the production of UHMWPE fiber.
