摘要

大豆蛋白胶因其可再生、可降解和环保性而受到广泛关注。豆胶的热反应特性和胶合特性研究结果显示:以20℃/min速率升温时,豆胶胶液在157℃时完全固化,在173℃开始降解;胶合板的胶合强度与涂胶量呈线性正相关。按热压温度160℃、热压时间80s/mm、压力1.6MPa、双面涂胶量450g/m2的工艺制备豆胶胶合板,其湿态胶合强度为0.78 MPa,满足GB/T 9846.3-2004《胶合板第3部分:普通胶合板通用技术条件》中Ⅱ类胶合板的要求。

Abstract

Derived from a renewable,biodegradable and environmentally friendly resource,soy protein adhesive（SPA）has been widely considered for a long time.The objective of the study was to evaluate thermal and bonding characteristics of SPA used in plywood manufacturing.At a heating rate of 20 ℃/min,the SPA samples totally cured at 157 ℃ and thermal degradation began at173 ℃.Testing results showed there was a positive linear correlation between glue consumption and bonding strength of the SPA bonded plywood samples.When the SPA plywood samples were made with 450g/m2 glue consumption（two sides）under 1.6 MPa pressure at 160 ℃ for 80s/mm,the wet bonding strength of the samples reached 0.78 MPa,which met the specification requirement of the National Standard GB/T 9846.3-2004 for typeⅡplywood.
