[中文摘要]
|
以原位法制备了纳米坡缕石增强PF复合材料。TEM表明,纳米坡缕石粉体在复合材料中分散均匀;IR特征:在约1085cm-1、1045cm-1等处分别为酚醛树脂中的醚键桥、羟甲基的固有红外吸收峰,而1191cm-1、1121cm-1、1094cm-1、987cm-1等处均属于坡缕石特殊结构中不同类的Si-O红外吸收峰;TG/DTA曲线表明,它们耐热性较好,明显优于普通酚醛树脂。用此复合材料作为基体树脂制备的无石棉编织型制动带,摩擦性能良好。

Nano-palygorskite
complex material was prepared by in-situ of polymerization. TEM showed that
nano-palygorskite powder in the complex materials
dispersed evenly. Its IR characteristic was shown,
it is ether linkage in PF resins and intrinsic infrared absorption peak of methylol with wave numbers around 1085 and 1045cm-1 respectively.
While wave numbers are at 1191, 1121, 1094 and 987cm-1 respectively, it is infrared absorption
peak of different Si-O bond in special
construction of palygorskite. TG/DTA curve
indicates that it possesses good thermostability ,and outstrips obviously common PF resins.Frication
properties of non-asbestos woven brake band used with these phenolic resin hybrids were well too.
