Description

一种树脂基摩擦材料及其制备工艺
技术领域
本发明涉及一种摩擦材料，具体地，涉及一种树脂基摩擦材料。
背景技术
现有的摩擦材料通常包括粘结剂、增强材料、摩擦性能调节剂、填料和混合料几部分，其中粘结剂一般采用酚醛树脂做原料，其存在的缺点是：耐热性差，热分解温度低，不适合高温摩擦片的生产；树脂的内聚强度低，造成摩擦制品的磨损率高，使用寿命短；树脂的韧性差，车辆在刹车时会产生噪音，摩擦片易碎损坏；游离酚含量高，所生产的摩擦片致密性较差。该类摩擦材料已经不能满足市场要求。
发明内容
本发明为解决上述问题，提供了一种具有良好硬度、耐热性、热稳定性、耐水性、粘结性的树脂基摩擦材料。
本发明树脂基摩擦材料由以下份数的组份组成，所述份数均为重量份：
苯并噁嗪树脂 40-60份；
硬脂酸锌 5-10份；
轻质碳酸钙 6-9份；
刚玉 5-10份；
炭黑 4-6份；
玻璃纤维 10-15份。
其中所述的苯并噁嗪树酯是通过以下方法合成的：
在室温下，依次向反应釜加入0.8-1kg4,4-二氨基二苯甲烷、2-3L二甲苯、0.5-0.8kg多聚甲醛，搅拌1-2h后升温至80-100℃，反应4-5h后，倒入减压蒸馏装置，经减压蒸馏除去多余溶剂，倒出冷却硬化后，用磨粉机磨粉待用。
所述硬脂酸锌、轻质碳酸钙、刚玉、炭黑均为市售200-300目产品。
所述玻璃纤维为20-30cm短纤维。
本发明树脂基摩擦材料制备工艺如下：
将苯并噁嗪树酯及其他组分依次加入JJ-5型胶砂机混合均匀，后经热压机180-220℃下热压6-10h成型，即得本发明摩擦材料。
本发明所具有的有益效果是：
1、本发明所用苯并噁嗪树酯耐热性好，硬度高，耐摩擦性能优异；
2、各组分协同作用，使得本发明不仅硬度高，韧性也较好；
3、合成工艺路线简单易操作。
