摘　　要：以氧化玉米淀粉为主要原料,采用环氧氯丙烷为交联剂,通过交联改性的手段,制备淀粉基木材胶粘剂。研究了环氧氯丙烷用量、反应温度、反应时间及pH值对产品性能的影响。研究结果表明,环氧氯丙烷的用量占物料总质量的4.0%,于50℃反应4 h,反应体系的pH值为10时制备出的木材胶粘剂综合性能较好,耐水性得到显著改善。The starch based adhesive for wood was prepared by crosslinking modification using oxidized corn starch as the main raw material and epichlorohydrin as the crosslinking agent. The effects of epichlorohydrin amount,reaction temperature,reaction time and p H value on the adhesive performance were investigated. The results showed that when the epichlorohydrin amount was 4.0 % by material total weight,the reaction temperature was 50 ℃,the reaction time was 4h and the system pH value was 10. the obtained wood adhesive had better overall performance,especially the water resistantance got prominence i mprovement.
