高光表面SMC的研究

STUDY ON HIGH GLOSS SURFACE SMC

本文主要对高光表面SMC进行了研究。采用正交实验设计法对影响SMC表面光泽度的主要影响因素LPA、MgO、CaCO3和模压温度进行了系统的探讨与分析,以SMC制品的表面光泽度和弯曲强度为参考值,得出了4因素对SMC制品表面光泽度的影响趋势曲线。综合表面光泽度和弯曲性能得到一组进一步优化的SMC配方,根据该配方所压制的SMC制品的表面光泽度可达到90,并具有较好的力学性能。

This paper studies the main factors that influence the surface finish of SMC products. LPA, MgO and CaCO 3 content and molding temperature are considered and optimized by using Latin Square Design. The influence of all the four factors on surface finish and flexural strength of SMC products is also discussed and the trend curvs are given respectirely. Finally, the SMC formulation is further optimized to get both excellent surface finish and high flexural strength simultaneously. SMC products produced by this formulation have the surface finish more than 90 as well as better mechanic properties.
