| 摘 要： | 采用己二酸(AA)、二乙烯三胺、环氧氯丙烷(ECH)合成聚酰胺多胺环氧氯丙烷树脂(PAE),将其与大豆蛋白按比例混合制备PAE大豆胶黏剂。在合成预聚体(PA)后,通过单因素试验,探究AA与ECH摩尔比、大豆蛋白添加量对胶合板胶合强度的影响,研究了PAE对大豆蛋白的改性作用及胶接机理。结果表明:在胶黏剂合成过程中AA与ECH摩尔比为1:1.0,大豆蛋白添加量为30%,热压温度为120℃、压力1.0 MPa、热压时间6 min条件下,PAE大豆蛋白胶黏剂胶合强度可达1.02 MPa,满足GB/T 9846-2015Ι类板指标要求。

| Abstract: | Adipic acid(AA),diethylenetriamine,and epichlorohydrin(ECH)were used to synthesize polyamine epichlorohydrin(PAE)resin,which was mixed with soybean protein to prepare PAE soybean adhesive.After the synthesis of prepolymer(PA),the effects of the molar ratio of AA to ECH and the amount of soybean protein added on the plywood bond strength were investigated through the single-factor experiment,and the modification effect of PAE on soybean protein and the bonding mechanism were studied.The results showed that during the synthesis of the adhesive,the molar ratio of AA to ECH was 1:1.0,the amount of soy protein added was30%,the hot pressing temperature was 120℃,the pressure was 1.0 MPa,and the hot pressing time was 6 min,the bonding strength of PAE soybean protein adhesive could reach 1.02 MPa,which meets the requirements of GB/T 9846-2015 Class-Ιplywood. |
