Abstract

Polymeric biocomposites based on TPU/recycled TPUW/mixed leather and SBR rubber waste unmodified/modified with polydimethylsiloxane/PE-g-MA in different percentages were made via the mixing technique on a Plasti-Corder Brabender mixer with an internal capacity of 350 cm. The waste, which came from the shoe industry, was cryogenically ground with the help of a cryogenic cyclone mill at micrometric sizes and different speeds. For the tests, standard plates of 150 × 150 × 2 mm were obtained in a laboratory-scale hydraulic press via the method of compression between its plates, with well-established parameters. The biocomposites were tested physico-mechanically and rheologically (MFI) according to the standards in force on polymer-specific equipment, also via FT-IR spectroscopy and microscopy, as well as via differential scanning calorimetry-DSC. Following the tests carried out, according to the standard for use in the footwear industry, at least two samples present optimal values (of interest) suitable for use in the footwear industry by injection or pressing in forming moulds.

摘要

基于热塑性聚氨酯（TPU）/回收热塑性聚氨酯废料（TPUW）/混合皮革和丁苯橡胶（SBR）废料，分别用不同比例的聚二甲基硅氧烷/马来酸酐接枝聚乙烯（PE-g-MA）进行未改性/改性处理，通过在内部容量为350立方厘米的Plasti-Corder Brabender密炼机上采用混合技术制备了聚合物生物复合材料。这些来自制鞋行业的废料，借助低温旋风磨在微米尺寸和不同速度下进行低温研磨。为了进行测试，通过在实验室规模的液压机中采用其平板间压缩的方法，在既定参数下获得了尺寸为150×150×2毫米的标准板材。根据聚合物专用设备上现行的标准，通过傅里叶变换红外光谱（FT-IR）、显微镜以及差示扫描量热法（DSC），对生物复合材料进行物理力学性能和流变性能（熔体流动指数，MFI）测试。在完成测试后，根据制鞋行业的使用标准，至少有两个样品呈现出适合通过注塑或模压成型模具用于制鞋行业的最佳（目标）值。
