摘要
采用直接铺膜法将多孔淀粉黄原酸酯经偶联剂KH-570改性处理后与天然胶乳复合,制备复合胶膜,考察KH-570对复合胶膜性能的影响。结果表明:加入偶联剂后,复合胶膜的热稳定性和耐溶剂性得到提高,耐水性降低,玻璃化转变温度(Tg)变化不大。经KH570改性后,复合胶膜的定伸应力、撕裂强度和拉伸强度均得到提高,偶联剂的用量为多孔淀粉黄原酸酯的3%时,复合胶膜的综合力学性能最佳。
Porous starch xanthate was modified with silane coupling agent KH-570,and then blended with natural rubber latex to prepare the porous starch xanthate / natural rubber latex film.The structure and properties of the resulted composite film,porous starch xanthate / natural rubber latex composite film,were investigated.The results showed that the composite film improved its thermal stability and solvent resistance,reduced its water resistance,and slightly changed its glass transition temperature.Loaded with KH-570 the blended film enhanced its stress,tear strength and tensile strength and exhibited optimum mechanical properties when the loading rate of KH-570 was 3％ of the porous starch xanthate.
