棉浆黑液提取物基木塑复合材料的制备及性能
Preparation and properties of wood-plastic composites based on extract of cotton spinning black liquor
摘要
Abstract
To efficiently utilize cottonseed black liquor,this study employed extracts of cottonseed black liquor as fillers,which were blended with high-density polyethylene and then molded using compression molding techniques to prepare wood-plastic composite(WPC)materials.The morphology,water absorption properties,thermal stability and mechanical performance of the materials were characterized using techniques such as Fourier-transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM),water absorption tests,water contact angle measurements,thermogravimetric analysis(TGA),flexural testing and tensile testing.A comparison was made with traditional materials such as corn stalks and lignin-based wood-plastic composites.The results revealed that the density of the cottonseed black liquor-based wood-plastic composite was 1.057g/m3 with a water contact angle of 97.75° and a water absorption rate of 0.95%,all meeting national standards.The onset decomposition temperature was 213℃with a residual char yield of 12.04%at 500℃.The flexural strength was significantly higher than that of corn stalks and lignin-based wood-plastic composites,while the tensile properties fell between the two,indicating excellent mechanical performance.关键词
