摘　　要：通过对丙烯酸酯 醋酸乙烯酯共聚乳液胶合成工艺研究 ,分析讨论了各因素对乳液胶质量的影响 ,选择了最佳工艺条件 (聚合温度为 85℃ ,聚合时间 4h ,引发剂 0 4%～0 6 % )及木材冷胶合调制配方。结果表明 :该乳液胶使用方便 ,成膜性好 ,胶合适用范围广 ,对木材冷压胶合后的板材强度可达Ⅰ类胶合板要求 (>0 96 5MPa)。表 7参By synthesis process of copolymer acrylates vinyl emulsion adhesive,the effects of influencing of the emulsion adhesive quality were analyzed and investigated.Both optimun synthesis process(polymerization temperature is 85 ℃,ploymerization time 4 h,initiator 0 4%～0 6%)and wood cold pressing adhesive conditions were selected.It was proved that it was easy of manipulating for the bonding,was good at forming film for the emulsion,and could be used every where.The bonding strength could meet requirements speeified in standard GB/T17657 1999(Ⅰ) plywood (bonding strength>0 965 MPa)for cold pressing adhesive of the emulsion.
