| 摘 要： | 为了开发利用玉米淀粉加工残余物(玉米醇溶蛋白)及制备环境友好刨花板,研究了二氯甲烷、玉米醇溶蛋白、制胶时搅拌温度等因素对基于玉米醇溶蛋白胶粘剂的木刨花板力学性能的影响。结果表明,当溶剂中二氯甲烷的体积百分含量在10%～50%范围内增加时,刨花板的静曲强度、弹性模量、抗拉强度及内结合强度等力学性能均呈现先增加后下降的趋势,当二氯甲烷含量为20%时,刨花板的各项力学性能达到最佳;当玉米醇溶蛋白的百分含量在20%～40%范围内增加时,刨花板的各项力学性能也均呈现先增加后下降的趋势,当玉米醇溶蛋白含量为30%时,刨花板的各项力学性能达到最佳;当制胶温度在25℃～65℃范围内增加时,刨花板的各项力学性能均呈现下降趋势,当温度为25℃时,刨花板的各项力学性能最佳。实验室测得玉米醇溶蛋白胶粘剂制备的刨花板力学性能值达到国家标准(GB4897-2003)。

| Abstract: | In order to utilize zein from residues of corn starch processing, and to develop an environmental friendly particleboard, effects of methylene dichloride, zein and the temperature of making glue on the mechanical properties of particleboard based on zein adhesive were investigated. The results show that when the volume percentage of methylene dichloride was increased from 10% to 50%, the values of mechanical properties of particleboard, such as modulus of rupture, modulus of elasticity, tensile strength and... |
