摘　　要：呋喃树脂是一种具有优良工艺性能的铸造用粘结剂,但呋喃树脂主要成分糠醇的快速涨价,限制了呋喃树脂的推广应用。分别采用相对糠醇价格便宜且性质活泼的材料:改性木质素、乙醇、山梨醇、木糖醇母液来对制备铸造用自硬呋喃树脂的主要成分糠醇进行部分替代。以抗拉强度为主要检测指标,确定了各个替代材料的用量。替代后的树脂强度高于或接近原树脂强度。Furan resin is an excellent binder for casting sand. Because the price of furfruyl alcohol （FA） as the essential component of furan resin soars presently, its application is limited. The cheap and active substitute materials： modified lignin, ethanol, sorbierite, xylitol mother liquor, are used partly for FA in the study. Based on the tensile strength, the amount of the various substitute materials is determined. The resin using substitute materials has higher or approaching tensile strength compared with the resin with single FA.
