玻化微珠/废PMMA复合材料的制备与性能研究
|
摘要
以废聚甲基丙烯酸甲酯(PMMA)为基料、甲基丙烯酸甲酯(MMA)为活性溶剂、玻化微珠为填料、过氧化苯甲酰(BPO)与N,N-二羟乙基对甲苯胺(DHET)组成的氧化-还原体系为引发剂,采用本体浇铸聚合法,在低温条件下制备玻化微珠/废PMMA复合材料。考察了废PMMA含量、玻化微珠用量及引发剂用量对复合材料硬度、强度等力学性能以及密度、光泽度等物理性能的影响,采用扫描电子显微镜观察复合材料的断面形貌。研究发现,随着废PMMA含量、玻化微珠用量和引发剂用量的变化,复合材料的力学性能和物理性能受到不同程度的影响。研究结果表明:在废PMMA质量分数为25%～30%,玻化微珠用量为20%～25%(质量分数),引发剂用量为0.26%(质量分数)时,复合材料的综合性能优良。采用硅烷偶联剂KH-560处理玻化微珠,可有效地提高复合材料的力学性能和光泽度,为建筑装饰领域提供一种新的装饰材料。
Glass microbeads/waste PMMA composites were prepared by using bulk polymeration under the condition of low temperature,which waste PMMA as basic material,methyl methacrylate(MMA)as the active solvent,glass microbeads for packing,oxidation-reduction system of benzoyl peroxide(BPO)and N,N-2 hydroxyethyl of toluidine(DHET)as initiator.Investigation on the effects of waste PMMA concentration,dosage of glass microbeads and initiator to mechanical properties such as hardness,strength and physical properties such as density,gloss of the composites.And the cross section morphology of the composites was observed by scanning electron microscope(SEM).It was found that the mechanical properties and physical properties of the composites were influenced to varying degrees with the changes of waste PMMA concentration,dosage of glass microbeads and initiator.The results showed that the composites had good comprehensive performance when waste PMMA concentration was 25 wt% ～30 wt%,dosage of glass microbeads was 20 wt% ～25 wt%,dosage of initiator was 0.26 wt%.The mechanical properties and gloss of composites could be effectively improved by using KH-560 of silane coupling agent.A choice of new decorative materials can be offered for the field of architectural decoration.
