摘　　要：通过对介绍以淀粉、甲醛、苯酚为原料,在酸性条件下,淀粉水解成D-葡萄糖,脱水生成羟甲基糠醛,与苯酚合成酚醛树脂胶粘剂,合成胶粘剂的粘结性能与未改性的酚醛树脂胶粘剂相比较,没有多大变化,而且减少甲醛的用量,降低了成本。本课题拟用淀粉部分取代甲醛合成淀粉改性酚醛树脂胶粘剂,通过正交试验研究甲醛用量、淀粉用量、pH等因素对样品性能的影响,找出最佳工艺配方。The starch, formaldehyde, phenol as raw materials is introduced, in acidic conditions, hydrolysis of starch into D - glucose, glucose dehydration to generate HMF with phenol synthesis of phenolic resin adhesive, synthetic adhesive bond performance and is not modified compared to phenolic resin adhesive. There is not much change, and to reduce the amount of formaldehyde, to reduce costs. Intended to be the subject of partial replacement of starch synthesis of starch modified phenolic formaldehyde resin adhesive, through the study of formaldehyde in the amount of orthogonal test, starch dosage, pH and other factors affect the performance of samples to identify the optimum formulation.
