摘要
松香是一种非常重要的化工原料,其具有防潮、防腐、粘性、乳化性和绝缘性等优点。我国拥有丰富的松树林,每年生产的松香占世界市场的60%。天然的松香存在着易被氧化、软化点低、易于重金属盐反应的缺点,因此对松香进行改性,优化松香的性能,扩大其在涂料、油墨、粘结剂、家具清漆等领域应用范围。文章评述了松香酯化的研究进展,同时对松香酯化进行了展望。
Rosin is a very important chemical raw materials with a damp-proof, antiseptic,sticky, emulsifying and insulating advantages.There is a large number of pine tree in china so that can produce rosin occupied 60% the world market very year.Natural rosin has a low softening point,easy to be oxidized and to react with heavy metallic salt so that rosin must be modified in order to improve it＇s property and enlarge it＇s application in dope,painting ink,binder, varnish of furniture and so on.The paper made a comment and outlook about the research progress of the esterification of rosin.
