The present research work deals with the preparation of semi-synthetic leather using fruit vegetable waste, acrylic polymer resin, and additives. Glycerol and polyvinyl acetate were used as additives to improve the flexibility and crack resistance properties. The leather film was prepared by pouring a mixed solution containing fruit vegetable waste powder, acrylic resin, and additives into the aluminium mold and drying in the oven at 120 °C for 4 h. Optimization of the concentration of acrylic resin, polyvinyl acetate, glycerol, as well as the powdered fruit vegetable waste, was studied. The characterization was performed to analyze mechanical properties and structural analysis using standard testing methods and instruments. The findings disclose that the optimized specimen with a recipe of 40% acrylic resin, 5% fruit vegetable waste powder, 5% polyvinyl acetate, 5% glycerol, and 45% water exhibits tensile strength of 112.1 N, elongation of 91%, tear strength of 15.06 N, and flexural rigidity of 62.44 mg.cm. It was also observed that the concentration of the acrylic resin, powdered fruit vegetable waste, and additives have a significant correlation with the mechanical properties. The abrasion resistance of the film was excellent for 20,000 abrasion cycles. FTIR analysis confirmed no alteration in the chemical structure after film preparation.

果蔬废弃物用于半合成革的增值

目前的研究工作涉及利用果蔬废料、丙烯酸聚合物树脂和添加剂制备半合成皮革。使用甘油和聚醋酸乙烯酯作为添加剂来提高柔韧性和抗裂性能。将含有果蔬废粉、丙烯酸树脂和添加剂的混合溶液倒入铝模具中并在120℃的烘箱中干燥4h来制备皮革薄膜。研究了丙烯酸树脂、聚醋酸乙烯酯、甘油以及粉状果蔬废弃物的浓度优化。使用标准测试方法和仪器进行表征以分析机械性能和结构分析。结果表明，配方为40%丙烯酸树脂、5%果蔬废粉、5%聚醋酸乙烯酯、5%甘油和45%水的优化样品的拉伸强度为112.1 N，伸长率为91%，撕裂强度15.06 N，弯曲刚度为 62.44 mg.cm。还观察到丙烯酸树脂、粉状果蔬废料和添加剂的浓度与机械性能具有显着相关性。该薄膜的耐磨性在 20,000 次磨损循环中表现优异。FTIR 分析证实薄膜制备后化学结构没有变化。
