Abstract: The present invention provides a two-component thermally conductive adhesive composition and a two-component thermally conductive gap-filling glue. The composition comprises: 8-38 wt% of an acrylate monomer or a combination of an acrylate monomer and an acrylate oligomer, with a glass transition temperature ranging from -80°C to -10°C; 0.2-4 wt% of a peroxide oxidant; 0.05-1 wt% of a peroxide decomposition promoter; and 60-90 wt% of a thermally conductive filler, wherein the two-component thermally conductive adhesive composition comprises Part A and Part B. Part A comprises a peroxide oxidant and Part B comprises a peroxide decomposition promoter; the acrylate monomer, or the combination of the acrylate monomer and the acrylate oligomer, and the thermally conductive filler exist in one or both of Part A and Part B. The products of the two-component thermally conductive adhesive composition and the two-component thermally conductive gap-filling glue after curing have a high elongation-at-break, high thermal conductivity and low bonding strength to aluminum metal surfaces, and are suitable for use as a thermally conductive gap-filling material in the battery pack module of an electro-mobile.
