Abstract

The influence of the content of camphorquinone (CQ), amine (DABE), and inhibitor (MHQ) on the Wallace indentation hardness of light-curing polymers was investigated. The hardness was measured on disc-shaped specimens made from 50 bisphenol-A-glycidyl-dimethacrylate/triethyleneglycol-dimethacryla te-based monomers with various contents of CQ, DABE, and MHQ. When no MHQ had been added, the hardness number decreased with increasing content of CQ. This was also the case with increasing content of DABE, but to a lesser extent. In the presence of MHQ, the contents of CQ and DABE did not influence the hardness number significantly.

摘要

研究了樟脑醌（CQ）、胺（DABE）和抑制剂（MHQ）的含量对光固化聚合物的华莱士压痕硬度的影响。在由含有不同含量CQ、DABE和MHQ的50份双酚A-缩水甘油二甲基丙烯酸酯/三乙二醇二甲基丙烯酸酯基单体制成的圆盘形试样上测量硬度。当未添加MHQ时，硬度值随CQ含量的增加而降低。DABE含量增加时情况也是如此，但程度较小。在有MHQ存在的情况下，CQ和DABE的含量对硬度值没有显著影响。
