Research on Silicone-modified Boric Phenolic Resin

(2-Hydroxyphenyl) propyl silicone oil(Si-phenol) was obtained via Williamson ether synthesis, Claisen rearrangement, and hydrosilylation, and then was mixed with phenol. The silicone. modified boric phenolic resin(SBPF) was synthesized via borate esterifieation. The structure of SBPF was analyzed by means of H-1 NMR and FTIR, and the heat. resistance and mechanical performances of SBPF were characterized by TGA, shearing test, tensile test, and impact test. The effects of Si. phenol content on various performances of SBPF were investigated, and the mechanisms were researched. The result shows that the synthesized resin has good heat. resistance, and the introduction of appropriate proportion siloxane segments could improve its adhesive property and enhance its mechanical strength.
