界面上的偶联剂分子结构对GF/UP体系流变特性的影响

EFFECT OF THE MOLECULAR STRUCTURE OF COUPLING AGENT ON THE RHEOLOGICAL PROPERTIES OF GLASSFIBER/UP SYSTEMS

摘要: 本文以有机硅烷及钛酸酯两类不同性质的偶联剂处理玻璃纤维,对所得的GF/UP体系测定了流变特性。实验表明,GF/UP体系的流变特性与偶联剂在界面上形成的结构形式有关,同样也与偶联剂的分子结构有关。硅烷类由于在GF表面形成刚性架结构,故体系具有较高的E_η值。偶联剂分子中的长链也是体系E_η增高的重要原因。E_η高的体系对温度的敏感性较高。文中同样讨论了偶联剂分子其它结构因素(如链数量、离子的存在、烷氧基等)对体系流变特性的影响。

Abstract: The rheological properties of the glass/UP systems which was obtained as a result of the treatment of glass fibers by two different coupling agents (organic silicane and titanate) was determined.The excperimental results show that the Theological properties of the glass/UP systems depend not only on the form of the strueture formed in interface,but also on molecular structure coupling agent.
