摘　　要： 通过显微分析、粘度分析、强度测试等方法研究了不饱和聚酯的用量及粘度等对树脂型人造石质量的影响,并分析了其机理。结果表明,不饱和聚酯用量不足,使粉料出现不均匀润湿,导致树脂型人造石表面出现斑印,弯曲强度下降;加入苯乙烯可降低树脂粘度,在一定程度上改善润湿效果,从而减少了树脂型人造石表面的斑印,并提高弯曲强度,但过高的苯乙烯掺量会使弯曲强度降低。当不饱和聚酯质量分数为7%,苯乙烯质量分数约1%时,树脂型人造石表面的斑印可基本消除。 The effects of unsaturated polyester content and viscosity on the quality of resin-based artificial stone were investigated by the microanalysis,viscosity analysis and flexural strength test.The mechanism was also analyzed.The results showed that the spots appeared on the surface of the resin-based artificial stone and decrease of flexural strength were caused by the insufficient amount of unsaturated polyester resulted the inhomogeneous wetting of powder.The addition of styrene could reduce the resin viscosity and improve the wetting effect to some extent.Therefore,the spots was reduced and the flexural strength was increased.The spots could be basically eliminated with the content of styrene 1% and unsaturated polyester 7%.
