摘要

选用硅烷偶联剂KH570对纳米Al

进行表面改性处理，并用改性后的Al

对双酚A环氧丙烯酸酯进行复合改性，研究了纳米Al

含量(1 % ( wt)~5% ( wt) )对树脂性能的影响。结果表明：改性纳米 Al

质量分数为5%时的复合材料的体积收缩率最小，为6.48%；粒子质量分数为2%时，树脂的凝胶率最大，为88.3%；热失重测试结果表明

改性纳米Al

提高了树脂的热稳定性；拉伸性能显示，随着改性纳米 Al

质量分数的增加，复合材料的拉伸强度先升高后下降，当改性纳米Al

质量分数为3%时，复合树脂拉伸强度最大，为34. 74MPa，与未改性树脂相比，拉伸强度提高了 108.27%。本文所制备的改性光敏树脂可适用于3D打印环境。

Abstract

In this paper

nano-Al

was modified by modifier KH570

and the modified Al

was used for the modification of bisphenol A epoxy acrylate. We studied the effect of the mass fraction of the modified nano-Al

(1 % (wt) ~5%(wt))on the properties of the resin. The results showed that the smallest volume shrinkage rate was 6. 48% when the connection of modified nano-Al

was 5 % ( wt) ; the highest gelling percent was 88. 3 % when the mass fraction of modified nano-Al

was 2 %. TGA test results showed that nano-Al

improves the thermal stability of the resin. Tensile results showed that with the increase of the mass fraction of the modified nano-Al

the tensile strength of the composite first increased and then decreased

and the tensile strength was the highest when the mass fraction of modified nano-Al

was 3%(the tensile strength was 34. 74MPa and increased by 108. 27%). The originality of this paper is that

first

we used modifier KH570 to modify the surface of nano-Al

making it easier to disperse in the resin matrix. Second

this modified photosensitive resin is suitable for 3D printing environment.
