Description

一种有机-无机复合材料及其制备方法和应用
技术领域
本申请属于复合材料技术领域,具体涉及一种有机-无机复合材料及其制备方法和应用。
背景技术
塑胶是常用的工程材料,它具有比重轻、易加工、制造成本低的特点,但其表面硬度低、易划伤、耐溶剂、耐紫外光老化性能差;而陶瓷具有高硬度、高耐磨性、高熔点、耐氧化等特点。陶瓷-塑胶复合材料能够有望兼顾陶瓷与塑胶的优点,具有广阔的应用前景。但陶瓷和塑料难以密切结合,普通陶瓷的烧结至少需要1200℃以上的高温,这是一般塑料所无法承受的,且陶瓷和塑料的线性热膨胀系数相差比较大,当陶瓷-塑胶复合材料在遭遇外界温度的急剧变化时容易发生两相的分离,难以满足市场需求。

第二方面,本申请提供了如上所述的复合材料的制备方法,包括:将塑胶和氧化铝进行第一混合,得到第一混合物;向第一混合物中加入铝酸盐进行第二混合,得到复合材料。
第三方面,本申请提供了如上所述的复合材料在电子产品上的应用。
本申请的发明人通过大量实验研究发现,55-90%的片状或棒状铝酸盐、10-30%的塑胶和0-15%的氧化铝共同形成的有机-无机复合材料,具有硬度高,强度高,抗冲击性能好等优点。

由表1 的测试结果可知,本申请方案实施例1-实施例14制备得到的复合材料的综合性能明显优于对比例1-3的复合材料的综合性能。其中,对比例3的各组分含量不在本申请范围内,虽然其流动性好,但其四点弯曲强度及抗冲击性均较差。
综上所述,本申请的复合材料在片状/棒状铝酸盐、塑胶、氧化铝的协同作用下,提高了复合材料的弯曲强度和抗冲击性能力。本申请提供的复合材料具有较高的硬度,弯曲强度和抗冲击性能。
以上描述仅为本申请的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解,本申请中所涉及的发明范围,并不限于上述技术特征的特定组合而成的技术方案,同时也应涵盖在不脱离所述发明构思的情况下,由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
