摘要
以羟基封端的聚二甲基硅氧烷(PDMS-OH)与三甲氧基硼氧六环(TMOB)为主要原料,采用缩聚方法制备线性硅硼聚合物;再加入异佛尔酮二异氰酸酯(IPDI)制备新型冲击硬化材料。在通过流变仪测试材料机械性能的基础上,采用傅里叶红外(FT-IR),核磁共振仪(NMR)和X射线电子能谱(XPS)等对材料结构进行表征。确定出新型冲击硬化材料最佳合成条件。同采用传统方法所合成的线性硅硼共聚物进行相比,新型冲击硬化材料具有更优越的抗冲击性能。
Hydroxyl-terminated polydimethylsiloxane （PDMS-OH） and trimethoxyborane （TMOB） as the main raw material were used for the preparation of linear borosilicate copolymer via condensation copolymerization. With the intro duetion of isophorone diisocyanate （IPDI）, the novel impact hardening materials were synthesized. On the basis of the material mechanical properties testing by rheometer,the structure of materials were also characterized by fourier transform infrared （FT-IR）, nuclear magnetic resonance （NMR）, X-ray photoelectron spectroscopy （XPS）. Moreover, the optimum synthesis conditions of the impact hardening materials were determined. Compared with the materials prepared by the conventional method, the novel materials had superior anti-impact protective performance.
