摘要
随着表面活性剂原材料价格的上涨和人类对环保问题的日益重视 ,开发新的表面活性剂已成为金属切削液研究的重点之一。利用我国丰富的天然松香资源 ,合成表面活性剂 ,是原料来源方便 ,又具有环保意义的有效方法。在催化剂存在下 ,反应温度为 160~ 2 0 0℃时 ,松香与顺酐进行共聚反应 ,共聚物进一步与多元胺发生中和反应 ,生成了非离子表面活性剂HA 1。它具有优良的分散性、润滑性、防锈性 ,有着广阔的应用前景和极好的生态性能。可用作分散稳定剂、润滑剂、防锈剂、润湿剂等。添加在合成切削液中 ,显示出优异的综合性能 ,是合成切削液的一个突破。同时也为改性和利用松香提供了新的方法。
Because the price of surfactant material rised and environmnet protect has been considered more and more importat by people,it is very important to exploiture new surfactant in studying of metal cutting fluid.It is a viable and effective method to synthesize surfactant by making use of abundant rosin in China.HA-1 nonionic surfactant is synthesized by using rosin and diethanolamine as materials with the existence of catalyst at temperature of 160~200℃,and it showed good properties of dispersing stabilizing, lubricating and rusthibiting in water-synthetic cutting fluid.It is a great breakthrough in synthetic cutting fluid and of important sence of environment protect.At the same time,a method to modify and use rosin is acquired.
