Description
技术领域
本发明涉及一种添加硫酸钙晶须的聚丙烯复合材料及其制备方法。
背景技术
聚丙烯,简称PP,是由丙烯聚合而制得的一种热塑性树脂。按甲基排列位置分为等规聚丙烯(isotactic polyprolene)、无规聚丙烯(atactic polypropylene)和间规聚丙烯(syndiotactic polypropylene)三种。甲基排列在分子主链的同一侧称等规聚丙烯,若甲基无秩序的排列在分子主链的两侧称无规聚丙烯,当甲基交替排列在分子主链的两侧称间规聚丙烯。
一般工业生产的聚丙烯树脂中,等规结构含量约为95%,其余为无规或间规聚丙烯。工业产品以等规物为主要成分。聚丙烯也包括丙烯与少量乙烯的共聚物在内。通常为半透明无色固体,无臭无毒。由于结构规整而高度结晶化,故熔点可高达167℃。耐热、耐腐蚀,制品可用蒸汽消毒是其突出优点。密度小,是最轻的通用塑料。缺点是耐低温冲击性差,较易老化,但可分别通过改性予以克服。共聚物型的PP材料有较低的热变形温度(100℃)、低透明度、低光泽度、低刚性,但是有更强的抗冲击强度,PP的冲击强度随着乙烯含量的增加而增大。PP的维卡软化温度为150℃。由于结晶度较高,这种材料的表面刚度和抗划痕特性很好。PP不存在环境应力开裂问题。PP的熔体质量流动速率(MFR)通常在1~100。低MFR的PP材料抗冲击特性较好但延展强度较低。对于相同MFR的材料,共聚型的抗冲强度比均聚型的要高。
随着人们生活水平的提高,人们对材料的要求特别是产品的要求非常高,尤其是家电领域。PP以耐高温,成本低,环保而广泛应用在家电行业,但是由于结晶,PP的收缩率相当高,一般为1.6~2.0%,这严重影响产品的成型,而且家电产品外观要求光泽度高,表面需要耐刮擦,PP很难满足。
发明内容
本发明的目的是克服现有技术的缺陷,提供一种添加硫酸钙晶须的聚丙烯复合材料及其制备方法,使用硫酸钙晶须对PP改性后,降低PP材料的收缩率明显降低,提高产品尺寸的稳定性。
实现本发明目的的技术方案是:一种添加硫酸钙晶须的聚丙烯复合材料,具有以下质量分的组分:聚丙烯树脂35~75份,5~10μm硫酸钙晶须15~25份,玻璃纤维5~35份,弹性体5~10份,PP-G-MAH3~8份,抗氧剂0.2~1份,颜料0.2~2份、润滑剂0.2~2.0份。
优选地,具有以下质量分的组分:聚丙烯树脂60份,5~10μm硫酸钙晶须20份,玻璃纤维8份,弹性体6份,PP-G-MAH4份,抗氧剂1份,颜料0.5份、润滑剂0.5份。
上述技术方案所述聚丙烯树脂为等规结构聚丙烯。
上述技术方案所述玻璃纤维为10~15的无碱短切玻璃纤维。
上述技术方案所述弹性体为丁晴橡胶、二元乙丙橡胶、三元乙丙橡胶中的一种或多种。
上述技术方案所述抗氧剂为抗氧剂1010与抗氧剂168的复配物。
上述技术方案所述颜料为金红石型钛白粉。
上述技术方案所述润滑剂为脂肪酸类润滑剂。
一种添加硫酸钙晶须的聚丙烯复合材料的制备方法,具有以下步骤:
步骤1,按质量分配比称取原料;
步骤2,将聚丙烯树脂、弹性体、PP-G-MAH、抗氧剂、颜料和润滑剂添加到高速混合机中混合均匀;
步骤3,将5~10μm硫酸钙晶须和玻璃纤维通过侧喂料口加入双螺杆挤出机,其工艺为,T1210℃,T2220℃,T3230℃,T4240℃;整个挤出过程时间为1~2分钟,压力为12~18Mpa。
采用上述技术方案后,本发明具有以下积极的效果:
本发明使用5~10μm硫酸钙晶须部分替代玻璃纤维加入至聚丙烯复合材料的制作中,硫酸钙晶须由于在结晶时原子结构排列高度有序,其内部存在的缺陷很少,近乎完整晶体,因而它的强度和模量接近于材料原子间价键的理论强度。用它作为聚丙烯复合材料的增强组元,不但提高了材料的强度,也使得它在这些材料破裂过程中能够有效抑制裂纹扩展,而且纤维状物质能够吸收冲击能量,从而起到缓冲作用,达到增韧的效果。制作的聚丙烯复合材料收缩率降低明显,产品的尺寸稳定性明显提高,而且增加产品光泽度和表面耐刮擦性。
