摘要:

通过Williamson醚合成、 Claisen重排及硅氢化反应得到邻羟基苯丙基硅油(Si-phenol), 将其与苯酚混合, 采用硼酸酯法合成有机硅改性硼酚醛树脂(SBPF). 利用 1H NMR和FTIR技术对其结构进行分析, 采用热重分析(TGA)、 剪切测试、 拉伸测试以及冲击测试等手段对其耐热能和力学性能进行表征. 考察了Si-phenol的含量对树脂各项性能的影响, 并研究其作用机理. 结果表明, 合成的有机硅改性硼酚醛树脂具有良好的耐热性, 适量硅氧烷链段的引入可以改善树脂的黏接性能, 提高其力学强度.

Abstract:

(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 1H 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.
