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