摘　　要：本文研究一种用于制备微细砂轮的树脂金刚石复合材料,该复合材料由丙烯腈-丁二烯-苯乙烯(ABS)作为基体,聚氯乙烯(PVC)作为混料,邻苯二甲酸二辛酯(DOP)作为加工助剂,与金刚石磨粒混合而成。对5种不同配比的共混体系进行分子动力学模拟,结果显示:提高ABS的质量比,复合材料分子间作用力逐渐增强,密度逐渐降低,延展性和柔性先减小后增加,ABS和PVC的相容性先减小后增加,复合材料最佳配比为62.5wt%ABS、18.6wt%PVC、8.3wt%DOP和10.6wt%金刚石磨粒。This article studies a resin diamond composite material for melt deposition molding(FDM),which is composed of acrylonitrile-butadiene-styrene(ABS)as the matrix,polyvinyl chloride(PVC)as the mixture,dioctyl phthalate(DOP)as a processing aid,mixed with diamond grinding particles.Molecular dynamics simulations of five different ratio blending systems,the results shows:improve the quality ratio of ABS,the intermolecular forces in the composite material increase,the density correspondingly decreases,the ductility and flexibility first decrease and then increase,and the compatibility between ABS and PVC first decreases and then increases,The optimal ratio of composite materials is 62.5wt%ABS,18.6wt%PVC,8.3wt%DOP,and 10.6wt%diamond abrasive particles.
