Description

一种电力电表外壳材料的制备工艺
技术领域
本发明属于电力材料加工领域,具体公开了一种电力电表外壳材料的制备工艺。
背景技术
电表是电能表的简称,是用来测量电能的仪表,又称电度表,火表,电能表,千瓦小时表,指测量各种电学量的仪表。电表外壳主要起着保护电表内部零件的功能,需要良好的机械性能,很好的热稳定性和阻燃性能。国内目前电表外壳材料多采用阻燃ABS。虽然阻燃ABS价格低廉,但刚性不是很好。国外目前多采用增强聚碳酸酯(PC),随着我国经济的发展,国内也将大量采用增强PC作为电表外壳材料。聚碳酸酯是一种无色透明的无定性热塑性材料,其化学性质为耐弱酸、耐弱碱、耐中性油、不耐紫外光和不耐强碱,其物理性质为线膨胀率:38×10cm/cm2,热变型温度135℃,具有稳定性差、存在应力易于裂开、对缺口抗冲击力低、耐磨性差、对金属件粘合力低、粘度大、流动性差和影响加工注塑成型等缺点。 
目前国内外研究的较多的是聚碳酸酯改性电表外壳材料,其主要成分是聚碳酸酯,添加其他阻燃材料,其往往存在强度不够或热稳定性较差的缺陷,各种性能无法兼备;而且大量使用聚碳酸酯成本较高,降低了企业的利润空间。中国发明专利CN101469118A公开了一种电表壳用高分子材料,该高分子材料机械强度不够,并且成本较高,不利用推广使用。中国发明专利CN103740078A是申请人在先的发明专利,公开的外壳材料具备较好的机械强度和阻燃性能,但是热变形温度较低,容易变形,不适合高温环境下。
发明内容
本发明的目的是解决现有技术中电表外壳材料的诸多缺陷,经过大量试验和探索,改变现有的原料组成及制备方法,提供一种电力电表外壳材料的制备工艺。
为了实现上述目的,本发明的技术方案通过如下方式来实现的:
一种电力电表外壳材料的制备工艺,其包括如下步骤:
按照重量份称取下述各原料,其中,聚氯乙烯90-100份,聚乙烯60-70份,甲基丙烯酸甲酯40-50份,玻璃纤维38-42份,聚碳酸酯30-36份,聚乳酸25-28份,十溴二苯乙烷20-22份,聚二甲基硅氧烷18-20份,甲壳素12-15份,氮化硅粉10-12份,碳化硅粉7-8份,琥珀酸钠4-5份,滑石粉2-4份,硫酸钡2-3份,石墨粉1-2份;
将各原料依次加入离心机中,1000转/min离心搅拌3分钟,混合均匀后,进入双螺杆挤出机挤压成熔融状态,然后用注射机将熔融体快速注入模具中,模具合模冷却定型;开模后成品进入副模,在副模内通过切割机切边即得。
优选地,玻璃纤维的长度优选为1-5mm;氮化硅粉、碳化硅粉、琥珀酸钠、滑石粉、硫酸钡以及石墨粉的粒径均控制在200目以上。
本发明取得的有益效果如下:
