Description

一种短切玻纤增强聚甲醛材料
技术领域
    本发明属于高分子新材料领域,尤其涉及一种短切玻纤增强聚甲醛材料及其制备工艺,该材料用来替代部分有色金属或合金,扩大其在汽车、电子电气、精密机械等行业的应用范围。
背景技术
    聚甲醛(POM)是一种无支链的线型高结晶性聚合物,因其具有独特的力学性能、优异的耐磨性和自润滑性、耐油性、耐化学药品性、抗蠕变性及良好的热、电性能,吸水率低,能在较宽的温度范围内保持其所具有的力学、化学性能和电性能,被广泛应用于汽车、电子电气、家用电器、精密机械和建筑材料等行业。但在一些较为苛刻的条件(高温、高速或高压)下,普通的POM的强度或刚性并不能满足其使用要求。为进一步提高POM的强度和刚性,可以通过加入一定量的无机增强材料来实现。短切玻纤作为无机增强材料中的一种,有成本低、强度高、耐高温、抗氧化、耐腐蚀等优良性能,并且增强效果显著,在共混挤出过程中适应性较强,是用来增强改性POM的理想材料。而且共混改性作为简单有效的制备工艺,便于操作,宜于规模化生产。但在加工过程中,由于玻纤与POM二者之间不易润湿,界面间的结合较弱,所以如何处理玻纤表面是制备高强度玻纤增强材料的关键。
发明内容
    本发明所要解决的技术问题是提出一种短切玻纤增强聚甲醛材料及其制备工艺,使其制备的增强聚甲醛材料具有较高的强度,同时不影响制品的外观,可用来替代部分有色金属或合金。
     为了解决上述技术问题采用以下技术方案:一种短切玻纤增强聚甲醛材料,由下列重量份的原料制成:共聚甲醛树脂50~80份、短切玻纤10~30份、吸醛剂1~10份、防玻纤外漏剂0.1~5份、偶联剂0.1~5份、抗氧剂0.1~5份。
所述的共聚甲醛为三聚甲醛和二氧五环的共聚物。
所述的吸醛剂为三聚氰胺、双氰胺、聚丙烯酰胺或聚酰胺中的一种或几种的混合物。
所述的防玻纤外漏剂为改性乙撑双脂肪酸酰胺(TAF)。
所述的短切玻纤为无碱短切玻纤。
所述的偶联剂为偶联剂KH-550、偶联剂A-1100或偶联剂A-172中的一种或几种的混合物。
所述的抗氧剂为自抗氧剂1010、抗氧剂245或抗氧剂168中的的一种或几种的混合物。
短切玻纤增强聚甲醛材料的制备工艺如下:
(1)按重量份称取原料;
(2)将上述除短切玻纤外的原料加入容量为50kg的混色机中混合均匀;
(3)将混合好的原料加入双螺杆挤出机的加料斗中,短切玻纤经侧喂料口加入,挤出造粒,挤出机转速100~400r/min,温度175~225℃;
(4)将制得的增强聚甲醛粒料放入干燥烘箱,以80℃干燥4h,最终得到产品。
本发明采用聚甲醛作为基体树脂,通过短切玻纤增强制得一种高强度的聚甲醛材料,其拉伸强度达到125MPa,弯曲强度达到180MPa,缺口冲击强度达到7.5kJ/m2,综合性能优良,可以满足聚甲醛在汽车、电子电气、精密机械等行业的应用要求。
利用双螺杆挤出机采用共混改性的制备工艺,简单有效,便于操作,宜于规模化生产;该工艺通过加入一定量的短切玻纤,利用玻纤的强度和刚性,使应力在POM基体和玻纤界面之间进行有效的传递,从而使基体得以增强;同时通过加入合适比例的偶联剂、吸醛剂、防玻纤外漏剂和抗氧剂,来改善POM的稳定性以及外观。使用偶联剂A-1100增强了玻纤与聚甲醛的界面间的结合作用,利用本工艺制得的POM材料的拉伸强度比未增强的POM提高65MPa,弯曲强度提高95MPa,缺口冲击强度提高1.5kJ/m2;所加入的吸醛剂、抗氧化剂和防玻纤外漏剂用量少,加入之后不会影响到制品的外观;防止了因玻纤的加入而引起的聚甲醛的热稳定性的降低。因此,本发明所述的增强改性聚甲醛具有优异的拉伸性能、冲击性能以及良好的热稳定性。
