项目标书摘要：为满足原位聚合原液着色聚酯产业化对乙二醇基超细颜料色浆的粒径分布、稳定性等性能的要求，本课题研究了不同分散剂对颜料表面改性、分散作用，对颜料颗粒在乙二醇溶剂中储存稳定性的影响，并筛选了满足聚酯原位聚合高温体系应用要求的颜料和分散剂；开发了高储存稳定性乙二醇基超细颜料色浆的配方和制备工艺；评价了高储存乙二醇基超细颜料色浆的聚酯原位聚合应用性能。最终完成了乙二醇基超细颜料色浆的配方和工艺优化。完成了5000吨/年产能的乙二醇基超细颜料色浆生产线建设，建成乙二醇基超细颜料色浆全自动连续化制备示范线，建立高储存稳定、窄粒径分布的乙二醇基超细颜料色浆的产品标准、评价方法、生产技术规范以及乙二醇基超细颜料色浆标准颜色数据库，实现聚酯原位聚合用高储存稳定、窄粒径分布的乙二醇基超细颜料色浆连续工业化生产。经下游客户原液着色聚酯原位聚合的规模化应用证实，本课题开发的乙二醇基超细颜料色浆满足聚酯原位聚合规模化应用要求。

Application Abstract: In order to meet the requirements of the particle size distribution and long-term storage stability of the ethylene glycol-based ultrafine pigment dispersion used in the industrialization of the in-situ polymerization of polyester,the effects of different dispersants on the surface modification,dispersing characteristics and long-term storage stability of the pigment dispersed in the ethylene glycol were studied.The pigments and dispersants that meet the application requirements of the polyester in-situ polymerization were selected.The formulation and preparation process of ethylene glycol-based ultrafine pigment dispersion with high storage stability were developed.The application properties of polyester in-situ polymerization with high storage ethylene glycol-based ultrafine pigment dispersion were evaluated.Finally,the optimization of formulation and process of ethylene glycol-based ultrafine pigment dispersion was completed.We have completed the construction of a 5000t/a production line of ethylene glycol-based ultrafine pigment dispersion,and built a demonstration line for the automatic and continuous preparation of ethylene glycol-based ultrafine pigment dispersion.We established the product standards,evaluation methods,production technical specifications of ethylene glycol-based ultrafine pigment dispersion with long-term storage stability and narrow particle size distribution,and the standard color database of ethylene glycol based ultrafine pigment dispersion.The ethylene glycol-based ultrafine pigment dispersion has been successfully used in the continuous industrial production of polyester in-situ polymerization.The large-scale application of the downstream customers confirmed that the ethylene glycol-based ultrafine pigment dispersion developed in this project meets the requirements of the production of polyester in-situ polymerization.
