摘要： 针对我国高速列车涂装中对原子灰的特殊需求，采用 TDI(2，4-甲苯二异氰酸酯)对不饱和聚酯树脂改性。结果表明:改性后的不饱和聚酯树脂原子灰的柔韧性、耐冲击性均得到了改善，从而提高了高速列车外表大修的运行里程。

Abstract: With the special demand on putty for painting high-speed trains in China, an unsaturated polyester resin modified by TDI was investigated. The results showed that the flexibility and impact resistance of putty based on modified unsaturated polyester resin were improved, prolonging the running mileage of higl-speed trains before overhaul.
