| 摘 要： | 采用高速均质剪切法制备氰酸酯树脂（CE）/纳米二氧化硅（nano-SiO2）复合材料,通过测试粘度变化,考察了nano-SiO2对复合材料粘度的影响.结果表明：nano-SiO2能够极大提高复合材料的胶粘性;相对于纯CE,3.00%nano-SiO2含量,工作温度90℃时复合材料粘度的相对提高率为67.99%;工作时间8h时复合材料粘度的相对提高率为51.51%.

| Abstract: | The CE/nano-SiO2 composites were made by a high-speed homogeneous shearing method.The effects of the nano-SiO2 on the viscosity of CE/nano-SiO2 composites were investigated through viscosity changes test.The results indicated that nano-SiO2 did well in improving the adhesive properties of CE/nano-SiO2 composites.Compared with pure CE that the viscosity of CE/nano-SiO2 composites was increased by 67.99% at 3.00% nano-SiO2 and 90℃,that means the relative decrease rate of composites viscosity was 51.51% at 8 hours. |
