Alkaline zinc - manganese battery is widely used all over the world it has good performance of storage ， low cost ， stable discharge and convenience of carrying the sealing of the battery is a crucial factor to the performance of the battery due to the disadvantages of present sealants ， leakage of electrolyte often happens what ’ s more ， the sealing capability affects the performance of the battery the way to raise the sealing capability is to search for a good additive ， which can improve the sealing capability through adding according to chemical principles ， this article picks out ptfe and nylon66 as additive adding ptfe or nylon66 into the pitch can improve the sealing capability of the pitch at the same time ， the temperature ， the time ， the amount of addictive ， the way to drop temperature and the time of churning all should be considered by testing the constitutions ， softening point ， moving degree and length of needle of various pitch samples ， we can compare the properties of different sealants can be studied by using of x - ray , the constitutions of the pitch can be indicated which can help us to explain these changes this article includes ： testing the constitutions ， soften point ， moving viscosity and needle penetration of various pitches ； raising the sealing capability by adding ptfe nylon66 into the pitches ； testing the constitutions ， soften point ， moving viscosity and needle penetration of raised samples ； analyzing and discussing the basic principles of this method it is showed that soften point ， moving viscosity and needle penetration of pitches are increased by adding ptfe nylon66 and the discharge time ， initial voltage ， capacity of battery with pitch raised by nylon66 are good and get to the requirement of gb t7 1 1 2 in a11 the method proposed in this article is available in practical industry use 通过测定改进沥青的软化点、运动粘度和针入度等指标参数来比较不同的添加剂及不同的添加条件对沥青封口性能的影响。本论文的主要研究结果为：系统测试了多种沥青样品的组成、软化点、运动粘度、针入度；对市售沥青分别添加聚四氟乙烯乳液、有机硅树脂和尼龙66进行改进，制备了改进产品；对改进沥青的组成、软化点、运动粘度、针入度进行了测试和比较；使用改进沥青组装成电池并对电池进行恒电流放电测试、短路电流测试和电池漏气、漏液性能的测试；对沥青改进的原理进行了分析和讨论。实验结果表明：在沥青中添加尼龙66和聚四氟乙烯乳液对沥青的封口性能有明显的提高；通过对工艺条件的不断改进，目前的工艺条件已完全可以用于实际生产操作；以添加尼龙66改进的沥青为封口剂组装成的电池完全满足碱锰电池生产的需要，且电池电容量、短路电流等指标均达到gb t7112标准要求；本文提出的改进方案，通过验证是一种效果好、实用性强的方法。
In this work , nylon 66 / montmorillonite nanocomposite was prepared ; mechanical and heat properties were tested , and the structure and crystallization behavior of the composites were also characterized , which were compared with that of pure nylon 66 . the main results can be summarized as follows : 1 本文以尼龙66为基体，天然钠基蒙脱土为填料，采用熔融插层法制备了尼龙66蒙脱土纳米复合材料，测试了复合材料的力学性能和热性能，表征了材料的结构和结晶行为，并和尼龙66作了对比。
