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
