摘要

研究了木塑复合材料的力学性能和生物降解性能。以40wt%的山毛榉木粉（WF）为增强基材，马来酸酐（MA）为偶联剂，添加纳米粘土以改善性能。所研究的聚合物是聚羟基丁酸酯（PHB），另一种聚合物是高密度聚乙烯（HDPE）。生产了三组复合材料，在两组中，每种聚合物单独使用，在第三组中，两种类型的聚合物的组合用作基质。使用8重量%和12重量%的淀粉代替共聚物。使用双螺杆挤出机和注塑机对试样进行混合，并进行机械测试：拉伸强度和模量、弯曲强度和模量，抗冲击性测试和

Comparison of Resistance and Biodegradability Properties of Wood-Plastic Composites from Wood Flour/PHB/HDPE/Starch

. In this study, mechanical and biodegradability properties of wood-plastic composite were investigated. Beech wood ﬂ our (WF) 40 wt% was used as a reinforcing base material, maleic anhydride (MA) as a coupling agent, and nano clay to improve the properties were added. The polymer studied was polyhydroxy-butyrate (PHB) and the other polymer was high-density polyethylene (HDPE). Three groups of composites were produced, in two groups each of the polymers alone and in the third group a combination of two types of polymers was used as a matrix. Starch 8 wt% and 12 wt% was used instead copolymer. The specimens were mixed using a twin-screw extruder, made with an injection-molding machine, and subjected to mechanical tests: tensile strength and modulus, bending strength and modulus, impact resistance tests and
