摘要
研究了多元醇丙烯酸酯的成分和不同条件下制备的含Si_3N_4的硅烷化填料对复合材料的强度和耐磨性的影响。本文制备的含Si_3N_4-多元醇丙烯酸酯功能高分子材料,在齿科后牙修复中,是无毒的和生物活性的,活的组织与其能产生界面间的结合,其抗压强度可达3800kg/cm^2,硬度(布氏)达135,优于国外Adapic、Composite同类材料。
This paper deals with the effect of composition of polyol acrylate and siliconting fill containing Si3N4 prepared in different conditions on the strenth and wearproof of composite. The paper reported that the polymeric material of polyol acrylate containing Si3N4 is nontoxic, biologically active,and used for dental restoration. The polymeric material firmly combine with tissue through surface bridge. The compression strenth of the material can reach 3800 Kg/cm2, and Brinell hardnes is 135. These properties are superior to those products known as Adapic Composite.
