Description

一种聚甲醛与聚丙烯复合改性塑料
技术领域
本发明涉及一种塑料配方，具体涉及一种聚甲醛与聚丙烯复合改性塑料。
背景技术
聚丙烯比重小，强度、钢度、耐热性均优于低压聚乙烯，具有优良的耐腐性，良好的高频绝缘性，不受湿度影响，表面硬度和耐热性较好，但成型收缩率大，低温易变脆，不耐磨，易老化。聚甲醛有优异的机械性能，尤其是弹性模量很高，刚性和表面硬度都很高，具有卓越的耐磨性和自润滑性，但收缩率大，热稳定性差，易分解老化。
发明内容
本发明的目的在于提供一种收缩率小、热稳定性好、耐老化、耐低温、韧性好、耐磨性好的聚甲醛与聚丙烯复合改性塑料。
本发明的技术方案是，一种聚甲醛与聚丙烯复合改性塑料，包括聚甲醛、聚丙烯以及添加剂，所述的添加剂包括填充剂、增韧剂、抗氧化剂、热稳定剂以及耐低温剂，所述的填充剂为云母粉，所述的增韧剂为苯乙烯-丁二烯热塑性弹性体，所述的抗氧化剂为叔丁基对苯二酚，所述的热稳定剂为二月桂酸二丁基锡，所述的耐低温剂为聚矾。
在本发明一个较佳实施例中，所述的聚甲醛与聚丙烯复合改性塑料各成分重量百分比为聚甲醛占26%-37%，聚丙烯占41%-47%，云母粉占12.6%-14.5%，苯乙烯-丁二烯热塑性弹性体占3.5%-4.4%，叔丁基对苯二酚占2.4%-3.3%，二月桂酸二丁基锡占2.1%-2.9%，聚矾占1.4%-1.9%。
在本发明一个较佳实施例中，所述的聚甲醛与聚丙烯复合改性塑料各成分重量百分比为聚甲醛占32.4%，聚丙烯占42.6%，云母粉占13.1%，苯乙烯-丁二烯热塑性弹性体占4.2%，叔丁基对苯二酚占3.2%，二月桂酸二丁基锡占2.7%，聚矾占1.8%。
本发明所述为一种聚甲醛与聚丙烯复合改性塑料，使制得的聚甲醛与聚丙烯复合改性塑料具有收缩率小、热稳定性好、耐老化、耐低温、韧性好、耐磨性好等功效。
