羟丙基淀粉合成工艺的研究

STUDY ON THE SYNTHESIS METHOD OF HYDROXY-PROPIONIC STARCH

探讨了羟丙基淀粉的合成工艺方法及各种工艺因素对改性淀粉粘度、取代度及剥离强度的影响，结果表明：以菱粉为原料，经过氧化、醚化处理所获得的烃丙基淀粉，具有粘度低、稳定性及粘接强度好等特点，可用于纸加工涂布胶粘剂、织物上浆及无纺织物胶粘剂等。

This paper reports the synthesis method of hydroxy-propionic starch,and studies theinfluences of technological conditions on viscosity,substitution value and stripping. The re-sults show that taking the starch of water caltrop as material,oxided and etherified starchhas low viscosity,fair adhesion and stability,it can be used as starching,adhesive of cloth,paper and so on.
