This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.

本文是以大豆分离蛋白为原料，进行SPI的化学修饰以提高其胶粘特性；采用了磷酸化试剂三聚磷酸钠、乙酰化试剂乙酸酐、琥珀酰化试剂琥珀酸酐和有机溶剂尿素修饰和变性SPI，研究修饰和变性后的SPI作为木材胶粘剂的胶粘性与耐水性，同时研究了两种方法复合修饰SPI对其粘度、胶粘强度和耐水性的影响；然后以SPI为原料，进行7S和11S球蛋白的提取以及胶粘特性的研究，对SPI起胶粘特性的机理进行了初步探讨。

Firstly, wettability and adhesive properties of the major soy protein components conglycinin (7S) and glycinin (11S) after urea modification were characterized. Modified 7S and 11S soy proteins were evaluated for gluing strength with pine, walnut, and cherry plywood and for wettability using a bubble shape analyzer. The molecular structure change was studied by chemical analysis, DSC and Rheometer. The results showed that different adhesives had varying degrees of wettability on the wood specimens.

液滴形状分析结果表明不同的胶粘剂在不同的木块上有不同的湿润性能，7S蛋白经过尿素变性后在胡桃木和樱桃木上有较好的湿润性能，11S蛋白经过1 mol/L尿素变性后在松木上有好的湿润性能。1 mol/L尿素变性使得11S蛋白在三种木块上的胶粘强度在所有胶粘剂中为最大；3 mol/L尿素变性使得7S蛋白在胡桃木和樱桃木上的胶粘强度比11S的大，但在松木上的胶粘强度则是11S/3M高于7S/3M。
