摘要
目前人造板生产中大量使用的甲醛基树脂胶黏剂已成为室内甲醛污染的首要来源,极大影响着人们的健康与工作、生活质量.近些年来,大豆蛋白胶黏剂因其无毒、可生物降解、成本低、加工方便等优点,在木材胶黏剂领域受到广泛的关注.然而,相较于目前广泛商用的酚醛树脂、脲醛树脂等商用的醛基胶黏剂,大豆蛋白胶黏剂存在胶合强度低、耐水性和防霉性能差等缺陷.针对上述问题,采用交联改性、共混改性、结构改性、水解酶改性和填充改性等物理化学手段对大豆蛋白胶黏剂进行功能化改性进而提升其性能是目前常用的手段.本文综述了不同的功能改性大豆蛋白胶黏剂的方法,总结了不同改性方法所存在的问题,并对其未来的发展提出展望.
Abstract
Nowadays,formaldehyde-based adhesives are heavily used in the production of WBP,which is the primary source of indoor formaldehyde pollution and severely affects people's health,work and living quality.In recent years,soy protein adhesives have attracted extensive attention in the field of wood adhe-sives because of their advantages such as non-toxic,biodegradable,low cost and convenient processing.However,compared with the widely used commercial formaldehyde-based adhesives such as phenolic resin and urea-formaldehyde resin,soy protein-based adhesives have some shortcomings in low bonding strength,poor water resistance and poor mildew resistance.In view of the above problems,it is commonly used to functionalize soy protein adhesives by physical and chemical means such as cross-linking modifi-cation,mixed modification,structure modification,hydrolase modification and filling modification.The dif-ferent methods of functional modification of soy protein adhesive were reviewed,the problems of different modification methods were summarized,and the future development of soy protein adhesive was prospec-ted.
