摘　　要：以单硅型偶联剂巯丙基三甲氧基硅烷(MPS)、三烯丙基异氰脲酸酯(TI)为原料,使用2,2-二甲氧基-2-苯基苯乙酮为光引发剂,365 nm紫外光下反应获得了三硅型偶联剂(TI-MPS),产率94%。通过红外光谱、核磁谱图确定了产物结构。研究TI-MPS水解液在金属表面固化后的性能,结果表明,在马口铁片表面固化后的TIMPS膜层耐冲击大于100 cm·kg,耐弯曲1级,极化电阻为7 459.3Ω·cm2,各项性能均优于单硅型MPS膜层。盐雾加速腐蚀实验表明,TI-MPS防护性能明显优于MPS,在用于铝片的防护时可耐1 000 h盐雾腐蚀。Tri-silane coupling agent（TI-MPS） was synthesized with a yield of 94% by reaction of 3- mercaptopropyltrimethoxysilane （ MPS ） with triallyl isocyanurate （ TI ）, with 2, 2-dimethoxy-2- phenylacetophenone （DMPA） as photoinitiator, under 365 nm UV-light. The structure of the reaction product TI-MPS was confirmed by Fourier Transform Infrared Spectroscopy and 1HNMR spectrum. The properties of TI-MPS hydrolyzate after curing were studied. The results show that the cured TI-MPS layer on iron sheet could withstand an impact of more than 100 cm ·kg with its bending level at grade 1. The polarization resistance of the layer is 7 459.3Ω· cm^2. The performance of TI-MPS layer was superior to that of the single silane MPS layer. Salt spray accelerated corrosion tests show that the protective performance of TI-MPS is better than that of bein~ able to resist 1 000 h salt spray test.
