［Objective］To solve the difficulties of synergistic improving the heat resistance andbonding performance in the study of high-temperature resistance modification of silicone pressure-sensitive adhesives（SPSA）.［Methods］A series of modified crosslinkers were successfully prepared by grafting methyl acrylate，benzyl acrylate，and tetrahydrofurfuryl acrylate onto hydrogen-containingcrosslinkers through hydrosilylation reaction. By adjusting the dosage of these modified crosslinkers， the 180° peel strength，loop tack，cohesive strength，and high-temperature residual adhesive content ofSPSA were systematically evaluated to analyze the impact of modification on bonding performance andheat resistance.［Results］The introduction of acrylates significantly enhanced the bonding ability of SPSA. Specifically，benzyl acrylate-modified SPSA exhibited high peel strength（>3. 67 N/cm）and loop tack（>12. 675 N）while elevating the residue-onset temperature to 280 ℃，greatly enhancing heat resistance.［Conclusion］This work achieved synergistic optimization of bonding performance and heat resistanc in SPSA. The application of benzyl acrylate-modified crosslinkers provided an effectivesolution to address high-temperature residue and insufficient adhesion，which was conducive to expanding the engineering applications of SPSA in high-temperature environments.
