惯性约束聚变实验用玻璃微球堵口特种胶研究

 通过对不同固化和热处理过程后的胶粘剂的剪切强度、表面形貌特征、热性能的研究，分析了增韧剂和偶联剂对环氧有机硅胶粘剂性能的影响。研究表明：随着增韧剂含量的增加，胶粘剂热分解温度下降；增韧剂质量分数为25%时，有机硅与环氧树脂相容性较好，制备的胶粘剂综合性能较好；硅烷偶联剂能改善胶层与金属界面的胶接强度，提高环氧有机硅胶粘剂的拉伸剪切强度。显微组织观察分析表明，环氧有机硅胶粘剂中环氧树脂分子链与有机硅高分子链处于一定微相分离状态。

Special adhesive for hollow glass microsphere sealing in inertial confinement fusion experiment

The preparation of the special adhesive for hollow glass microsphere sealing in the inertial confinement fusion(ICF) experiment was introduced.The influences of the toughener and coupling agent on the morphology,thermal properties and shear strength of the adhesive were analyzed.The test results indicate that the thermal decomposition temperature of the epoxy silicone adhesive decreases with the increasing of the toughener content,the comprehensive property of the epoxy silicone adhesive is the best when the toughener content is 25%.The coupling agent can improve the bonding strength of the adhesive-metal interface and the mechanical property of the epoxy silicone adhesive.The micro-structure study shows that the micro-phase separation exists between the epoxy molecular chain and the silicone molecular chain of the epoxy silicone adhesive.
