摘要
用油类改性剂，对脲醛胶亚麻屑碎料板进行改性研究结果表明：优化后的改性处理工艺条件为温度７５℃、时间２５ｍｉｎ、压力０．７５ＭＰａ、密度０．７ｇ／ｃｍ３、后真空时间３０ｍｉｎ、后真空度０．０９ＭＰａ。改性后的亚麻屑板的性能符合做铁路防冻害垫板的要求。
The paper investigated the modification of UF flaxboard with a kind of oilbased modification agent.The results indicated that the optimal processingparameters of modification techndogy were temperature,75℃,time,25min,pressure,0.75 MPa,density,0.75g/cm3 or0.8cm3, post vacuum time,30min,postvacuum pressure,0.09MPa,etc.The properties of modified flexboard werein coordination with the requirements of anti frostbite pad of railchalr in railway.
