摘　　要：介绍了一种用于制备水稻直播种纸的生物质胶黏剂,并对其合成工艺进行了研究。通过对玉米淀粉进行糊化、氧化、交联等化学改性,并以碱性稻草浆作为添加剂,研制出满足使用要求的生物质胶黏剂。探讨了氧化剂及交联剂对胶黏剂性能的影响,得出合成工艺条件为:氧化温度为50℃,氧化时间为120 min,氧化剂用量为6%(占淀粉的质量分数),交联剂与淀粉的质量比为2∶5,并对产物结构的红外光谱特征进行了分析。最后育种试验表明胶黏剂对种子生长无毒害作用。A kind of bio-based adhesive used for making the rice seeding sheet and its synthesizing process were introduced. The bio-based adhesive which met the requirement was prepared from starting material corn starch which was first modified by cooking with alkaline pulps, then oxidation and cross-linking. The influences of reaction temperature and time, dosage of oxidizer and cross-linkier on the properties of the adhesive were discussed. The synthesis condition was： oxidation temperature, 50 ℃; oxidation time,120 min ; oxidizer dosage, 6 % （based on starch） and mass ratio of cross-linkier to starch, 2 ： 5. The structure of the adhesive was characterized with IR. At last, the breeding test shown that there was no negative impact on the germination of seeds when using the adhesive.
