▎ 摘  要

NOVELTY - Two-component silicone potting adhesive comprises component A and component B with a mass ratio of 1:(0.7-1.5), where the component A comprising 100 pts. wt. POSS modified polysiloxane, 10-30 pts. wt. crosslinking agent, 0.1-0.8 pts. wt. inhibitor, amd 50-250 pts. wt. thermal conductive filler, and the component B comprising 100 pts. wt. POSS modified polysiloxane, 0.1-0.7 pts. wt. platinum catalyst, and 30-80 pts. wt. flame retardant additive. USE - Two-component silicone potting adhesive used in a power battery forming room temperature vulcanizing double component organic silicon sealing glue. ADVANTAGE - The two-component silicone potting adhesive has high heat conducting efficiency, good electric insulation and flame retardance, waterproof, shock-proof, which greatly improves the safety of the power battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a two-component silicone potting adhesive, which involves: a. mixing POSS modified polysiloxane, crosslinking agent, inhibitor and thermal conductive filler, grinding and vacuum defoaming to obtain component A; b. mixing POSS modified polysiloxane, platinum catalyst and flame retardant additive, grinding and vacuum defoaming to obtain component B; and c. mixing components A and B, defoaming in vacuum, pouring into a mold and solidifying at room temperature for 24-48 hours.
