摘　　要：为了提高建筑装饰用聚碳酸酯(PC)的耐刮擦性能,通过在聚碳酸酯(PC)中添加聚甲基丙烯酸甲酯(PMMA)的方法来提高材料性能,通过实验测试的手段研究PMMA对聚碳酸酯材料耐刮擦性能和光泽度的影响。研究结果表明:当PMMA加入量上升后,材料硬度随之提高,通过十字刮擦方法得到的色差值变化发生了先升高后降低的情况,材料色牢度降低。当摩擦次数上升后,所有材料的光泽度先迅速下降之后到达一个稳定的状态。PC/PMMA高分子材料的耐刮擦性能得到了改善。该研究有助于提高建筑装饰材料的高分子特性,为后续的化工精炼奠定一定的理论基础。In order to improve the scratch resistance of polycarbonate(PC)used for architectural decoration,polycarbonate(PC)was added with polymethyl methacrylate(PMMA)to provide the material performance.The influence of PMMA on the scratch resistance and gloss of polycarbonate material was studied by means of experimental testing.The results show that when the amount of PMMA increases,the hardness of the material increases,the color difference value obtained by the cross scraping method increases first and then decreases,and the color fastness of the material decreases.When the number of frictions increases,the gloss of all materials decreases rapidly and then reaches a stable state.A method to improve the scratch resistance of PC/PMMA polymer material is also given.This research is helpful to improve the polymer properties of building decoration materials and lay a theoretical foundation for the subsequent chemical refining.
