摘要
玉米淀粉对聚氨酯（ＰＵ）泡沫化学改性的研究郭金全，林剑清，戴李宗，岳建新（化工系）淀粉具有良好吸湿、降解和成本低廉等优点，用于对合成高分子进行改性无疑能赋予新的性质，因此本文无论在开辟淀粉资源的利用或新功能性高分子的研究均有重要意义［１，２］．基于淀...
in the foaming of Pn, corn starch was used to react with the isocyanate to participate the foaming recipe so that starch group was made to join in the molecular of of PU to make the foam chemical modifying. SEM and IR spectra were used for investigation of the structure and physical properties of PU foam with corn starch. The results showed that when the content of corn starch was in 50% the hygroscopicity of PU foam compared with the one without cornstarch increases by about 20 times and machanical properties of PU foam is good.
