摘要

目的开发并优化一种以小麦秸秆和沙柳为原料的可降解餐盒的绿色制备工艺。方法基于响应面法（RSM）中的Box-Behnken设计构建实验方案,以温度、时间和压力为自变量,以餐盒的力学性能（最大承受载荷）和耐水性（吸水率）为响应值,建立二阶回归模型。结果方差分析结果显示,该回归模型达到显著水平（P<0.01）,且证实各工艺参数间存在明显的协同作用。优化得到最佳工艺参数：热压温度、时间、压力分别为179.5 ℃、10.8 min、9.9 MPa;在此条件下制备的餐盒综合性能最优,最大承受载荷达（53.0±0.8）N,吸水率为（44.0±0.3）%。结论本研究为农业废弃物的高值化利用和开发环境友好的塑料替代品提供了可行的理论依据与工艺方案。创新之处在于首次将响应面法系统应用于小麦秸秆/沙柳这一特定混合体系的热压成型工艺优化,明确了关键工艺参数间的非线性影响与交互作用,为同类生物质复合材料的制备提供了新方法。

Abstract

The work aims to develop and optimize an eco-friendly preparation process for biodegradable meal boxes with wheat straw and Salix psammophila as raw materials. An experimental scheme was constructed based on the Box-Behnken design under response surface methodology (RSM), with temperature, time, and pressure as independent variables, and mechanical properties (maximum load-bearing capacity) and water resistance (water absorption rate) of the meal boxes as response values and a second-order regression model was established. Analysis of variance indicated that the regression model reached a significant level (P<0.01) and confirmed obvious synergistic effects among the process parameters. The optimal process parameters were determined as 179.5 ℃, 10.8 min, and 9.9 MPa. Under these conditions, the meal boxes exhibited optimal comprehensive performance, with a maximum load-bearing capacity of (53.0±0.8) N and a water absorption rate of (44.0±0.3)%. This study provides a feasible theoretical basis and process solution for the high-value utilization of agricultural waste and the development of environmentally friendly plastic alternatives. The innovation lies in the systematic application of response surface methodology (RSM) to the hot-pressing process optimization of the specific wheat straw/Salix psammophila blend system for the first time, which clarifies the nonlinear effects and interactions among key process parameters, providing a new method for the precise preparation of similar biomass-based composite materials.
