| 中文摘要: |
| 目的 为了改善大豆胶黏剂本身耐水性不足、胶合强度低的缺点，并有效利用环氧树脂胶黏剂优异的胶合强度、耐腐蚀性和机械强度，对大豆蛋白进行改性，制备大豆蛋白-环氧树脂环保型复合胶黏剂。方法 采用正交试验对复合胶黏剂的固含量、粘度和胶合强度进行分析与研究;探讨大豆蛋白质量，环氧树脂质量及顺丁烯二酸酐质量对胶黏剂胶合性能的影响。结果 最佳工艺参数为大豆蛋白20 g、环氧树脂20 g、马来酸酐4 g，所得的胶合强度达到1.60 MPa，满足国家Ⅱ类胶合板GB/T 9846—2004使用要求。结论 最佳工艺条件下的大豆蛋白胶黏剂的胶合强度显著提升，环氧树脂对大豆蛋白的改性效果较好。 |

| The work aims to modify the soybean protein with epoxy resin to prepare environment-friendly soybean protein-epoxy composite adhesive, so as to improve the water resistance and low adhesive strength of soybean adhesives, and effectively utilize the excellent adhesive strength, corrosion resistance and mechanical strength of epoxy resin adhesives. The solid content, viscosity and bonding strength of composite adhesives were analyzed and studied by orthogonal test. The effects of soybean protein quality, epoxy resin quality and maleic anhydride quality on the adhesive properties were investigated. When the optimum technological parameters of 20 g soybean protein, 20 g epoxy resin and 4 g maleic anhydride were obtained, the adhesive strength reached 1.60 MPa, meeting national Ⅱ kind of plywood (GB/T 9846—2004) requirements. The adhesive strength of soybean protein adhesives is improved significantly under the optimum conditions, and the modified effect of epoxy resin on soybean protein is better. |
