ABSTRACT Cultured marble is a blend of unsaturated polyester and calcium carbonate that is combined with pigments and additives to produce a wide range of colours and realistic, natural-looking patterns. This study aims to investigate process conditions (catalyst, temperature, cured time, etc …) of cultured marble at high temperatures. The optimized process conditions are obtained by thermal analysis from DSC with a temperature of 110°C and curing time of 20 min, respectively. The optimum catalyst for process conditions in a bulk moulding compound (BMC) machine is 2 phr of benzoyl peroxide (BPO). The styrene amount in UP resin is determined at 37.40% by the Gas chromatography-mass spectroscopy – headspace (GCMS-HS) technique. Anhydride maleic (MA) is found to improve outstanding mechanical properties in terms of flexural properties, the strength of impact, and the resistance of volume shrinkage of UP resin in cultured marble material.

低档添加剂对人造大理石材料收缩和力学性能的影响

摘要 人造大理石是不饱和聚酯和碳酸钙的混合物，与颜料和添加剂相结合，可产生多种颜色和逼真、自然的图案。本研究旨在研究高温下人造大理石的工艺条件（催化剂、温度、固化时间等）。优化的工艺条件分别通过 DSC 的热分析获得，温度为 110°C，固化时间为 20 分钟。块状模塑料 (BMC) 机器中工艺条件的最佳催化剂是 2 phr 过氧化苯甲酰 (BPO)。通过气相色谱-质谱-顶空 (GCMS-HS) 技术确定 UP 树脂中的苯乙烯含量为 37.40%。发现马来酸酐 (MA) 在弯曲性能方面可改善出色的机械性能，
