摘要 为降低人造大理石制造成本,拓宽石膏的应用领域,以经改性的二水石膏粉作为填料填充不饱和聚酯树脂(UP),采用常温浇注成型工艺制备人造大理石。研究表明,通过活化指数和接触角的变化,确定了改性最佳工艺条件。并通过对复合材料的黏度、力学性能等方面的测试和与氢氧化铝(ATH)作为填料的人造石板各个指标项目进行比较。结果表明,以硅烷偶联剂WD-70改性二水石膏粉,作为人造大理石填料不但可以增强板材的弯曲强度,而且能很大程度上降低人造大理石的生产成本。 To reduce the cost of artificial marble and enlarge the application field of gypsum. The artificial marble is made with the modified dihydrate gypsum powder, unsaturated polyester resin for raw material, adopting the normal temperature costing typecraft system. The research expresses that modified dihydrate gypsum powder were characterized with active exponent, contact angle, and compare the viscosity and mechanic properties of this composite with ATH as the filler of the artificial marble. The research indicated that dihydrate gypsum powder modified by silane coupling agent as the filler of the artificial marble not only can enhance the mechnical properties of the composition system, but also can reduce the cost of artificial marble.
