Description
技术领域
本发明属于电力材料领域，具体公开了一种电力电表外壳材料。
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。
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，其由如下重量份的原料制备而成：
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。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。
本发明还公开了上述电表外壳的制备方法，包括如下步骤：
按照重量份称取上述各原料，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。
本发明取得的有益效果如下：
本发明制备的电表外壳各原料组份之间具备较好的协同作用，能够达到较高的机械性能，并且具备优良的热稳定性和阻燃性能，适合用于高温环境下；本发明各原料成本低廉，低于市场常用的聚碳酸酯树脂电表外壳的成本，有利于降低企业原料成本，促进工业化生产。
