摘　　要：改性硅藻土与环氧树脂复合,加入固化剂,制得环氧树脂/硅藻土复合材料。测试了环氧树脂/硅藻土复合材料的固化性能及粘接性能。结果表明,硅藻土添加量为环氧树脂质量的6%时,固化过程的热焓最大,9%时复合材料的耐热性最好,1%时复合材料的拉伸剪切强度提高最多,但添加硅藻土对固化温度的影响不大。Epoxy resin/modified diatomite composite was prepared from epoxy resin,diatomite and curing agent.The curing properties and bonding properties of composite materials were measured.Results indicate that enthalpy can be highest when the amount of diatomite added is equivalent to 6% in mass ratio of the resin,heat-resistant of composite materials is the best when the diatomite dosage is 9% in mass ratio of the resin,the tensile-shear strength of composite materials is the largest when the diatomite dosage is 1% in mass ratio of the resin,content of diatomite has little effect on the curing temperature.
