油页岩灰渣制备人造大理石及其性能

利用油页岩灰渣、不饱和聚酯树脂为主要原料，辅助加入固化剂和促进剂，室温固化合成一种新型人造大理石装饰材料。运用实验系统研究原料配比、固化剂和促进剂用量、固化时间、树脂类型与填料粒度等因素对材料性能的影响，并确定了大理石制备的最佳配方。基层最佳配方（质量分数）：不饱和树脂1号为20%～27%、引发剂0.5%～2.25%、促进剂0.5%～1.5%、油页岩灰渣50%～70%、碳酸钙粉5%～20%；表层最佳配方（质量分数）：不饱和树脂1号为25%～30%、引发剂0.5%～2.0%、促进剂0.5%～2.0%、氢氧化铝40%～50%、碳酸钙粉20%～30%。采用该方法制备的人造大理石外形平整美观，压缩强度为79 MPa，弯曲强度为7.4 MPa，放射性比活度I_Ra和I_r分别为0.67、0.45，质量符合国家标准。

Preparation and Property Analysis of Artificial Marble from Oil Shale Ash

A novel kind of artificial marble has been synthesized by room temperature curing method,using oil shale ash and unsaturated polyester resin as the main raw materials,assisted by curing agent and accelerating agent.The effects of physicochemical properties on the performance of as-prepared samples have been investigated systematically,including the proportion of raw materials,the content of curing agent and accelerating agent,curing time,the type of resin and packing size.According to experiment,the optimiz...
