摘　　要：目的为了改善氧化淀粉的综合性能。方法以交联剂三氯化铁替代硼砂,采用高锰酸钾氧化法制备了无硼砂淀粉,并研究了交联剂三氯化铁用量、无机填料、高聚物等对氧化淀粉胶粘剂性能(黏度、初粘强度、防水性、粘合强度等)的影响。结果替代后的氧化淀粉胶粘剂不仅具有更好的黏度与初粘强度,而且其与无机填料以及高聚物均具有更好的兼容性。结论三氯化铁替代硼砂后所制备的氧化淀粉胶的防水性、粘结强度更好。Objective To improve the comprehensive properties of oxidized starch. Methods The non-boron starch adhesive was prepared using the potassium permanganate as oxidizing agent and FeCl3 as the cross-linking agent supplanting borax. The effects of FeCl3, inorganic filler and polymer on the properties of the oxidized starch adhesives （ such as viscosity, initial bonding strength, water resistance and bonding strength） were investigated. Results The result showed that not only the viscosity and initial bonding strength of the oxidized starch adhesives of the cross-linking agent FeCl3 was better than that of borax, but also both of the compatibility between the cross-linking agent FeCl3 and inorganic filler and polymer was better than that of borax. Conclusion The performances （such as water resistance and bonding strength） of the oxidized starch adhesive using the cross-linking agent FeCl3 are better than that of borax.
