Research on the mechanical performance of magnesium hydroxide whiskers/polymer composites

摘要

The modified and unmodified magnesium hydroxide whiskers (MH) were mixed with PE, PP, ABS matrix respectively. The mechanics performance of MH/polymer composites was tested by the universal testing machine. The effect of modified and unmodified MH whiskers' addition on the performance of composite material mechanics was studied. The results show that the whiskers modified by sodium stearate had a significant mechanical improvement to the MH/PE, MH/PP and MH/ABS composites than unmodified whiskers. The content of modified MH whiskers' added to PE, PP, ABS matrix materials are different when the best comprehensive mechanical properties are obtained, which are 20%, 20% and 40% respectively. Overall, the modified MH whiskers had a significant enhancement effect on the general plastics and engineering plastics.
