(2)将甘蔗渣和棉籽壳充分脱水干燥,再经粉碎机制成粉末,然后加入干秸秆粉和火山灰,充分混合均匀后加热至100-105℃保温混合10min,即得物料II;
(3)向物料I中加入物料II、石棉绒、珍珠棉、橡胶粉、乳化硅油、月桂二酸和纳米胶粉,充分混合后静置30min,再加热至135-140℃保温混合5min,最后经挤出机挤出并包裹在信号线线芯上。
所述乙烯-醋酸乙烯共聚物中醋酸乙烯的含量为25-30%。
所述增塑助剂由如下重量份数的原料制成:双酚A环氧树脂10-15份、线性低密度聚乙烯10-15份、聚乙二醇4008-13份、烯丙基聚氧乙烯醚6-11份、氢化松香5-9份、卡波树脂5-9份、活性白土4-7份、微晶纤维素4-7份、预胶化淀粉3-5份、聚丙烯酸钠3-5份、凡士林2-3份、环氧煤沥青2-3份、硫酸化蓖麻油1-2份、酯基季铵盐1-2份,其制备方法为:向双酚A环氧树脂中加入线性低密度聚乙烯和聚乙二醇400,先加热至130-140℃保温混合10min,再加入烯丙基聚氧乙烯醚、氢化松香和凡士林,于微波频率2450MHz、功率700W下微波处理10min,然后加入卡波树脂、活性白土、环氧煤沥青和硫酸化蓖麻油,充分混合后继续微波处理10min,最后待温度降至70-80℃后加入微晶纤维素、预胶化淀粉、聚丙烯酸钠和酯基季铵盐,充分混合均匀。
本发明的有益效果是:本发明以酚醛树脂为主要原料,辅以石棉绒、干秸秆粉以及多种助剂制得信号线内部绝缘吸震用填充材料,该填充材料质轻且制备成本低,具有优异的绝缘性、吸震性和阻燃性,有效保护信号线内部的线芯,延长其使用寿命,并提高使用安全性和减轻火灾隐患。其中增塑助剂的添加不仅能增强填充材料的柔韧性和曲挠性,还能提高挤出成型性。
