| 目的 研究一种环保生物质包装材料的热压成形制备工艺,并对其性能进行评价。 方法 将凤眼莲作为生物质原材料,通过磨浆并经水浴处理之后,添加助剂配方并经热压成形制备了环保生物质包装材料。 将助剂配方、热压温度、热压压力作为影响因素,进行正交试验,选取尺寸稳定性、力学性能、防水性能作为指标, 对其性能进行检测和综合评价。 结果 加入海藻酸钠 ( 0 . 8% ) , CMC-Na(0 . 4% ) ,琼脂(0 . 8% ) 作为胶黏剂,尿素(2% ) 作为增塑剂,乳化石蜡( 1% ) 作为防水剂,在热压温度为 150 ℃ ,压力为 10 MPa 条件下制得的生物质包装材料具有较好的综合性能。 结论 通过加入环保助剂配方,采用热压工艺可以制备出性能良好的生物质包装材料。 |

| Objective To study the hot-press preparation process of environmental packaging material and evaluate the performance of the material. Methods Water hyacinth was used as the raw biomass material in this study. The fibers were cracked, processed by hot water, supplemented with additives, and the environmental packaging material was finally prepared by hot-press. Using the formulation of additives, the temperature and the pressure of hot-press as influencing factors, orthogonal experiments were conducted. After the preparation, the dimensional stability, mechanical performance and water resistance were selected as indicators to test and evaluate the performance of the material. Results The results showed that using 0. 8% sodium alginate as adhesive, 2% urea as plasticizer,1% emulsion paraffin as water proof agent, the biomass packaging material prepared at 130 ℃ and under 10 MPa pressure had good comprehensive performance. Conclusion Biomass packaging material with good performance was prepared using hot-press technology in combination with the addition of environment-friendly additives. |
