Preparation and Characterization of Marble/Unsaturated Polyester Resin Composite Materials
A grey-white marble/UP composite material was prepared by using marble powder as the filler and Unsaturated polyester (UP) resin as the polymer matrix. Optimum amount of marble powder added into 100 g UP resin was 200g. The gel time and the curing time were 10.5min and 34min respectively, the peak temperature reaches 71.44°C, and heat-resistance temperature was enhanced by 81°C. Marble/UP composite material is smooth, equally distributed, and no aggregation of particles of marble powder.
