| Abstract: | Magnesium oxide powders were treated with four different silane coupling agents. The mechanical properties, heat deflection temperatures and heat conductive properties of magnesium oxide/nylon-6 composites treated by different coupling agents were studied, respectively. The results show that the strength and rigidity of magnesium oxide/nylon-6 composites treated by silane coupling agents are enhanced obviously, but the heat deflection temperatures increase slightly. With regard to the surface treatment of magnesium oxide, the sequence of four silane coupling agents from good to bad are KH792〉KH550〉KH160〉KH560. |
