In this paper, a complete biomass composite processing system based on agricultural waste powders, recycled plastics, and waste oil is proposed. The wood-colored wallpaper, the green wallpaper, and the blue wallpaper are produced by this processing system. These wallpapers are new products with low cost, high added value, and environmental friendliness. These wallpapers have also been systematically tested. Based on the analysis of test results, a 3D model of material formation mechanism, liquefaction filling technology, and hybrid network model construction technology are obtained. The experiment found the reasonable RLDPE and RLLDPE ratio (1:0.26), the reasonable ratio of biomass to specialty solvents (1:1.5), the reasonable dose of the solid dye (3%), and the reasonable concentration of dye solutions. Wood-colored bio-composite wallpaper products have a smooth surface, wood color (ΔE = 36.7), natural aroma, and good comprehensive mechanical properties (tensile strength 9.255 MPa; elongation at break 20.998%; Young's modulus 2229.475 MPa). The processing system and wallpaper products in this article not only promote the plastic recycling economy and sustainable agricultural development but also provide new channels for the development of waste oil reuse and new ideas for the development of high value-added biocomposite materials.
本文提出了一种完整的生物质复合材料处理系统，该系统基于农业废料粉末、回收塑料和废油。通过该处理系统生产出木纹壁纸、绿色壁纸和蓝色壁纸。这些壁纸是低成本、高附加值和环保的新产品。对这些壁纸进行了系统测试。基于测试结果的分析，得到了材料形成机理的 3D 模型、液化填充技术和混合网络模型构建技术。实验得出了合理的 RLDPE 和 RLLDPE 比例（1:0.26）、生物质与特种溶剂的合理比例（1:1.5）、固体染料的合理用量（3%）和染液的合理浓度。木纹生物复合材料壁纸产品表面光滑，具有木材颜色（ΔE=36.7）、自然香气和良好的综合机械性能（拉伸强度 9.255 MPa；断裂伸长率 20.998%；杨氏模量 2229.475 MPa）。本文中的处理系统和壁纸产品不仅促进了塑料回收经济和可持续农业的发展，还为废油再利用的发展提供了新的途径，为高附加值生物复合材料的发展提供了新的思路。
