摘要/Abstract

摘要：

以豆粕粉为主要原料，采用常温复配手段制备双组分豆粕胶黏剂，分析了亚硫酸添加量对胶黏剂的物理性能、固化黏弹性能及其制备的胶合板胶合强度的影响，并通过FT-IR对亚硫酸处理制得的双组分豆粕胶进行了结构表征。研究结果表明：亚硫酸能够降低胶黏剂体系的黏度，且当亚硫酸添加量为6%时，双组分豆粕胶黏剂的黏度和pH值适中，红外表征显示亚硫酸的加入能够促进蛋白质水解，暴露更多的活性基团。在120~150 ℃范围内，固化交联程度较高，固化黏弹性能较优，且用其制备的三层胶合板可满足国家标准Ⅰ类和Ⅱ类胶合板的要求，胶合强度分别达到了1.02MPa(100 ℃)和1.24 MPa(63 ℃)。

Abstract:

The two-component soybean meal adhesive was prepared by room temperature compounding method using soybean meal as the main raw material. The effects of the addition of sulfurous acid on the physical properties, curing viscoelasticity of the adhesive and the shear strength of the plywood were analyzed. The structures of the two-component soybean based adhesive that was prepared by the sulfurous acid treatment were characterized by FT-IR. The experimental results show that sulphate can reduce the viscosity of the adhesive system, and when the addition amount of sulfurous acid is 6%, the viscosity and the pH value of the two-component soybean meal adhesive are moderate. FT-IR shows that sulfite can promote protein hydrolysis and expose more active groups.The curing crosslinking degree and the curing viscoelasticity were better in the range of 120-150 ℃. The bonding strength of the three-layer plywood prepared by the two-component soybean based adhesive satisfies the requirement of the national standard for type Ⅰ and type Ⅱ plywood and reaches 1.02 MPa(100 ℃) and 1.24 MPa(63 ℃), respectively.

Key words: sulfurous acid, soybean meal adhesives, physical and mechanical properties, curing viscoelastic properties
