Description

汽车内饰件用抗静电PP/HDPE塑料及制备方法
技术领域
本发明涉及一种塑料材料及制备方法，尤其涉及一种汽车内饰件用抗静电PP/HDPE塑料及制备方法。
背景技术
聚丙烯，英文缩写为PP，是1957年于意大利首先投入工业生产，是继聚乙烯(PE)之后的又一个重要的塑料品种。它有较好的耐热性，在135℃蒸煮1000h也不会被破坏，PP的比热容、热导率皆小于PE，但绝热性优于PE。PP属于非极性聚合物，具有优异的介电性和电绝缘性，电性能基本不受环境湿度及电场频率的影响，在允许的工作范围内，温度升高会使电性能降低，它的耐电弧性较高。
高密度聚乙烯(HighDensityPolyethylene，简称为“HDPE”)，是一种结晶度高、非极性的热塑性树脂。原态HDPE的外表呈乳白色，在微薄截面呈一定程度的半透明状。
PP/HDPE塑料，具有良好的耐热性和耐寒性，化学稳定性好，但抗静电性不佳。
发明内容
一种汽车内饰件用抗静电PP/HDPE塑料，包括下述重量份的组分：聚丙烯100份，高密度聚乙烯20-30份，三元乙丙橡胶10-20份，3-氨丙基三乙氧基硅烷1-3份，抗静电剂0.5-1.5份。
优选地，所述抗静电剂为丙三醇单硬脂酸酯、烷基磷酸酯二乙醇铵盐、N,N-双(2-羟基乙基)-N-(3’-十二烷氧基-2’-羟基丙基)甲基硫酸甲酯铵和甘油单棕榈酸酯中的一种或其混合物。
最优地，所述抗静电剂由下述重量份的组分组成：所述抗静电剂由下述重量份的组分组成：丙三醇单硬脂酸酯20-30份，烷基磷酸酯二乙醇铵盐20-30份，N,N-双(2-羟基乙基)-N-(3’-十二烷氧基-2’-羟基丙基)甲基硫酸甲酯铵20-30份，甘油单棕榈酸酯20-30份。
丙三醇单硬脂酸酯，CAS号：123-94-4。烷基磷酸酯二乙醇铵盐，即抗静电剂P，英文名：Alkylphosphatediethanolaminesalt。甘油单棕榈酸酯，CAS号：26657-96-5。N,N-双(2-羟基乙基)-N-(3’-十二烷氧基-2’-羟基丙基)甲基硫酸甲酯铵，别名：抗静电剂609，英文名：N,N-bis(2-hydroxyethyl)-N-(3’-dodecyloxy-2’-hydroxypropyl)methylammoniummethosulfate。
进一步的，本发明还提供了一种汽车内饰件用抗静电PP/HDPE塑料的制备方法：按配比称取各原料，混合均匀后，熔融混炼、挤出造粒。
本发明的汽车内饰件用抗静电PP/HDPE塑料，具有较好的抗静电性能，可以用注塑工艺轻易加工成各种形状的汽车内饰件。
具体实施方式
下面结合实施例对本发明作进一步描述。聚丙烯为广东茂名石化公司生产的T30S，熔体流动速率MFR为2.0g/10min；高密度聚乙烯选用台湾塑胶公司牌号9001的HDPE树脂；三元乙丙橡胶选用日本三井公司牌号为4095的EPDM树脂。
实施例1-5
分别按照表1中对应实施例1-5数据称取各原料后，加入混合器中搅拌，控制转速在350r/min、搅拌温度80℃、搅拌时间3分钟，再经螺杆挤出机挤出造粒，挤出温度200℃，在15℃的冷水中冷却成型，即获得所述汽车内饰件用抗静电PP/HDPE塑料。
表1：汽车内饰件用抗静电PP/HDPE塑料配方表单位：公斤
测试例
对实施例1～5的PP/HDPE塑料表面电阻率进行测试，表面电阻率的测试方法按照GB/T1410-2006进行。
