摘　　要：研究了二氧化硅(SiO_2)对不饱和聚酯树脂(UPR)中苯乙烯挥发的影响。结果表明,SiO_2的加入可大幅降低苯乙烯在UPR储存期及固化过程中的挥发,且在UPR/SiO_2制备过程中采用超声分散,有利于降低苯乙烯在UPR储存期及固化过程中的挥发量;相比表面未有机处理的SiO_2,表面有机处理的SiO_2的加入更能有效降低苯乙烯在固化过程中的的挥发量。同时,还研究了不同制备工艺及不同表面性质的SiO_2的加入对UPR粘度、触变性及制品透光性的影响。The effect of SiO2 on the styrene volatility of unsaturated polyester resins （UPR） was studied. The results show that SiO2 can reduce the styrene volatility largely in the resin storage period and during the curing procedure. Preparation of UPR/SiO2 by the using of ultrasonic dispersion is advantageous in reducing the styrene volatility in the resin storage period and during the cu- ring procedure; The UPR with organically modified SiO2 reduces the styrene volatility effectively in the curing procedure,compared with UPR with no organically modified SiO2. At the same time, the influences of the different preparation procession and different surface properties SiO2 on the resin viscosity, the thixotropy and the light-admitting quality were studied.
