Description

PBT/弹性体/无机填料三元复合材料
技术领域
本发明涉及一种高分子材料,具体地说是一种PBT/弹性体/无机填料三元复合材料。
背景技术
聚对苯二甲酸丁二醇酯(PBT)是一种结晶型线形饱和聚酯树脂,已被广泛应用在电子电器、家电、汽车工业等行业,但由于其低温冲击韧性较差及室温下缺口敏感性大等缺点,限制它作为一种高分子结构材料在某些领域中的应用。现有技术采用弹性体增韧可以大幅度提高PBT的抗冲击性能,但同时也造成其强度、刚度、耐热性及加工性能的严重下降,同时成本也高;无机填料对PBT的刚性增强效果显著,但对PBT韧性提高幅度有限,且仅对有一定韧性的PBT才有增韧作用。
发明内容
鉴于上述现有技术存在的不足,本发明提供一种具备显著提高韧性、刚性、耐热性及综合性能优良的PBT/弹性体/无机填料三元复合材料。
本发明解决其技术问题所采用的技术方案是:PBT/弹性体/无机填料三元复合材料,其组分按质量百分数配比为:PBT 30%~70%、弹性体5%~25%、无机填料5%~50%、表面处理剂0.1%~0.5%、润滑剂0.2~1.5%、抗氧剂0.1%~1%。
所述的PBT为聚对苯二甲酸丁二醇酯,相对密度为1.31~1.35g/cm3,特性黏度为0.85~1.2dl/g,熔点220℃~240℃。
所述的弹性体为马来酸酐接枝乙烯-辛烯共聚物、马来酸酐接枝三元乙丙橡胶共聚物、马来酸酐接枝丙烯腈-丁二烯-苯乙烯共聚物和苯乙烯-顺丁烯二酸酐共聚弹性体中的一种。
所述的无机填料为平均粒径在20nm~10μm之间的碳酸钙、滑石粉、硅灰石和玻璃纤维中的一种。
所述的表面处理剂为硬脂酸、硬脂酸钙、硬脂酸钠、硬脂酸镁、钛酸酯、铝酸酯、硅烷和磷酸酯中的一种。
所述的润滑剂为聚硅氧烷、EVA蜡、OP蜡、TAS-2A和乙撑双硬酯酰胺中的一种或几种的混合物。
所述的抗氧剂为主抗氧剂1010与辅助抗氧剂168的复配物。
上述的PBT/弹性体/无机填料三元复合材料的制备方法,包括以下步骤:
(1)将PBT在130℃~140℃下干燥3~5小时,含水率控制在0.03%以下,待用;
(2)将无机填料在80℃~110℃下干燥3~6小时,再按重量配比称取干燥后的无机填料及表面处理剂,一起加入3000~8000转/分钟的高速混合机中,在维持80℃~110℃的温度下搅拌10~60分钟,使表面处理剂均匀包覆无机填料,然后冷却至低于40℃制得表面处理的无机填料,待用;
(3)按重量配比称取干燥处理后的PBT、弹性体、润滑剂和抗氧剂,加入高速混合机,同时加入经表面处理的无机填料,使充分混合3~10分钟;
(4)再将步骤(3)的混合物加入同向双螺杆挤出机中,控制螺杆转速为120~200转/分钟,机筒温度在170℃~230℃,通过双螺杆挤出机混炼、挤出造粒,即得PBT/弹性体/无机填料三元复合材料。
本发明的有益效果是,无机填料与弹性体具有并用增韧的协同作用,能使PBT的缺口冲击强度、刚度、耐热性和尺寸稳定性提高显著,其韧性提高幅度大于加入相同体积份数的弹性体,从而大大降低了弹性体的用量,使进一步降低成本,因此,具有显著的经济效益和社会效益。本发明所提供的制备方法简单和容易操作,易于工业化生产。
