γ—UPTES偶联剂的合成及其在GFRP中的应用

Synthesis of γ-UPTES Coupling Agent and Its Application in GFRP Materials

合成了新型长链硅烷-γ-+-烯酰氧丙基三乙氧基硅烷(γ-UPTES)偶联剂,确定了合成反应的条件,用红外光谱验证了其结构。研究了γ-UPTES在玻璃纤维增强材料(GFRP)界面上的偶联功能,表明经其处理的玻璃布制得的GFRP抗拉强度提高15％,抗冲击强度可提高近20％。

Synthesis of a new type of coupling agent-long chain silane γ-undecylenoxyl propyl triethoxy silane(γ-UPTES)was discussed and the experimental conditions for the synthesis reaction were determined.IR was used for the chemical structure characterization of the coupling agent.The coupling performance on an interface between it and glass fible in GFRP reinforced material was studied which showed that the GFRP material reinforced by glass fible which was treated with γ- UPTES has 15 % higher tensile strength and 20% higher shock strength than a normal GFRP.
