摘　　要：本文采用环氧树脂和水性聚酰胺对豆粕进行复合改性制备无醛胶黏剂,对豆粕胶黏剂的性能指标和胶合板的胶合强度进行了研究。通过正交试验得出以下最佳工艺参数:当热压温度为120℃、环氧树脂与水性聚酰胺改性豆粕溶液的质量比为20∶80、热压时间600 s时胶合板的胶合强度最高,为0.7628 MPa,达到国家标准GB/T 9846-2015中Ⅱ类胶合板使用要求。In this paper,the formaldehyde-free adhesive was prepared by the soybean meal modified with epoxy resin-waterborne polyamide,the properties of soybean meal adhesive and the bonding strength of plywood were studied.The optimal process parameters were obtained through orthogonal experiments,when the hot pressing temperature was 120℃,the mass ratio of epoxy resin to soybean meal solution modified with water-based polyamide was 20∶80,the hot pressing time was 600 s,the bonding strength of plywood was the highest(0.7628 MPa),which met the use requirements ofⅡtype plywood in the GB/T 9846-2015.
