摘　　要：用丙烯酸类三元共聚物作为分散剂,研究其在环氧树脂中对SiO2的分散效果。结果表明,添加分散剂后,树脂中的SiO2的沉降明显降低,悬浮率达到97.53%,有效控制了环氧浇注后的浇注材料分层现象。A kind of acrylic terpolymer was studied as dispersant agent in the casting system of epoxy resin to evaluate its dispersion effect on the Silicon Dioxide.The results show that the sedimentation of Silicon Dioxide was decreased and suspending rate was up to 97.53% with the addition of terpolymer.The internal delimitation of the casting material was effectively controlled during the epoxy casting process.
