Description
技术领域
本发明涉及配电箱领域，具体地说，涉及一种配电箱壳体材料及其制备方法。
背景技术
配电箱是电力行业中比较重要的设备之一，目前我国的配电箱壳体材料主要有两种：木制和金属制。木制配电箱，存在透气性差、不阻燃的缺陷；金属制配电箱，多采用铁皮或镀锌板加工制作而成，需要经过冲压、焊接、脱脂、除锈、水洗、中和、表调、磷化、烫洗、烘干、喷涂和组装，加工工序多、时间长，而且加工过程中会产生大量的废水等污染物，金属制配电箱普遍存在不绝缘的问题。
发明内容
为解决上述问题，本发明提供一种具有阻燃效果的、成本较低的木塑材料配电箱箱体及箱体的制备方法。
本发明所述的木塑材料配电箱箱体，包括以下重量份的组份：木粉60-80份、聚乙烯塑料50-90份、磷酸胺类阻燃剂5-15份、马来酸酐接聚乙烯3-15份、硬脂酸钙2-8份、硬脂酸锌2-8份、三盐基硫酸铅2-8份、抗氧剂1010 2-10份、稳定剂2-6份、防霉添加剂2-10份、抑烟剂3-8份。
优选的，所述稳定剂为钡锌复合稳定剂，防霉添加剂为纳米Zn0，抑烟剂为氢氧化镁或硼酸锌。
优选的，所述木粉粒度为60-100目。
本发明的另一个目的是提供一种上述木塑材料配电箱体的制备方法，包括以下步骤：
(1)将磷酸胺类阻燃剂制成20-30％(W)的溶液；
(2)将(1)中溶液加入高速混合机中，然后向高速混合机中加入木粉混合均匀；
(3)然后加入聚乙烯塑料、马来酸酐接聚乙烯、硬脂酸钙、硬脂酸锌、三盐基硫酸铅、抗氧剂1010、稳定剂、防霉添加剂、抑烟剂，混合均匀；
(4)将(3)中混合物塑化，后制成板状型材；
(5)将板状型材分别加工成配电箱的门、底座、顶盖和后壳体，然后组装成配电箱箱体。
与现有技术相比，本发明的有益效果是：
(1)采用磷酸胺类阻燃剂，阻燃效果好，磷酸胺类阻燃剂为膨胀性阻燃剂，通过酸源、炭源、气源的协同作用，能够在材料表面形成致密的多孔泡沫炭层，进而阻止内层的材料进一步降解和可燃气体的释放，同时能够隔断热量的传递，阻止火焰的蔓延和传播。
(2)所采用的磷酸铵类阻燃剂，含有N、P两种元素，具有无卤、低烟、阻燃的特点，阻燃剂为环保型阻燃剂。
(3)本发明所用的原料为废弃的塑料与木材，提高了废弃资源的利用率。
(4)本发明所制备的材料性质良好，具备较高的硬度和强度。
