江阴职业技术学院 毕业论文 课题： 丁基橡胶的混炼及混炼胶的质量控制 专 业 高分子材料应用技术 学生姓名 郭振平 班 组 10高分子（1）班 学 号 指导教师 宋功品 完成日期 2013.4.15 摘 要 丁基橡胶（简称IIR）是世界上第四大合成橡胶（SR）胶种，是异丁烯和异戊二烯在Friede-Craft催化剂作用下进行阳离子聚合反应的产物Butyl rubber (IIR) is the worlds fourth largest synthetic rubber (SR) adhesive, Is the product of isobutylene and isoprene cationic polymerization catalyzed by Friedel-Craft catalyst. Butyl rubber has excellent air tightness, water tightness and excellent weather resistance and chemical corrosion resistance, is a kind of tube and tubeless tire seal liner irreplaceable. This paper introduces the present status of production technology of butyl rubber, focuses on the formulation, butyl rubber mixing equipment, mixing process, summed up the different characteristics of different mixing device and mixing methods advantages and disadvantages, and based on the analysis of influence factors of butyl rubber mixing quality, and finally with the mix quality detection standard to analyze the common quality problems and put forward reasonable suggestions and optimization scheme. Key word: The formulation equipment mixing process quality control 目 录 摘要…………………………………………………………………………………Ⅰ Absract………………………………………………………………………………Ⅱ 第一章 丁基橡胶概述……………………………………………………………1 1.1丁基橡胶介绍…………………………………………………………………1 1.2丁基橡胶的炼胶原材料………………………………………………………1 1.3丁基橡胶的应用与发展………………………………………………………3 第二章 丁基橡胶的混炼设备………………………………………………………5 2.1密炼设备………………………………………………………………………5 2.1.1密炼机结构………………………………………………………………5 2.1.2密炼机操作方法…………………………………………………………6 2.2开炼设备………………………………………………………………………7 2.2.1开炼机结构………………………………………………………………7 2.2.2开炼机操作方法…………………………………………………………8 第三章 丁基橡胶的混炼工艺……………………………………………………9 3.1丁基橡胶混炼配方…………………………………………………………9 3.2丁基橡胶混炼工艺流程……………………………………………………9 3.2.1上料辅机系统……………………………………………………………9 3.2.2胶料混炼系统……………………………………………………………10 3.2.3下料辅机组………………………………………………………………10 3.3混炼工艺参数…………………………………………………………………11
