摘要/Abstract

摘要： 以黄麻纤维为增强体，经NaOH改性后的豆腐渣/淀粉混合溶液为基体，通过湿法模压制备黄麻/豆腐渣/淀粉复合材料。利用正交试验设计方案研究了豆腐渣/淀粉复配比、黄麻纤维含量、热压温度、热压强度、热压时间对复合材料板材拉伸性能和亲水性能的影响。结果表明：当豆腐渣/淀粉复配比为3、黄麻纤维含量为20%、热压强度为6Mpa、热压温度为80℃、热压时间为2min时，复合材料板材的拉伸断裂强度最优。试验所制备的复合材料片材亲水性较好，表明其具有较差的耐水性能。

Abstract: Jute/soybean dregs/starch composites were prepared by wet lamination method with jute fiber as a reinforcement phase and soybean dregs/starch solution modified by NaOH as a matrix phase.The effects of the mass ratio of soybean dregs/starch, mass fraction of jute, hot-pressing temperature, hot-pressing strength, and hot-pressing time on the tensile properties and hydrophilicity of the composite sheets were studied by orthogonal experiment design. The results showed that when the mass ratio of soybean dregs/starch was 3：1, mass fraction of jute was 20%, compression intensity was 6 MPa, hot-pressing temperature was 80°C, and hot pressing time was 2 min, the tensile fracture strength of the composite sheet was the best. The prepared composite sheets have good hydrophilicity, but poor water resistance.

Key words: jute/soybean dregs/starch, composite, tensile property, hydrophilicity
