Abstract

The effect of epoxidized soybean oil on the operational, technological, and physical and mechanical properties of composites based on high-density recycled polyethylene filled with wood floor was investigated. It has been shown that the introduction of epoxidized soybean oil in the amount of 0.5 wt.% into the wood-polymer composite (WPC) improves the physical, mechanical, and operational properties of the material: the Charpy impact strength (on notched samples) increases from 7.5 kJ/m to 20.0 kJ/m, the bending strength increases from 31.6 MPa to 50.8 MPa, and the coefficient of linear thermal expansion decreases by 15%. With a further increase in the content of epoxidized soybean oil in the composite, its water absorption and technological shrinkage decrease, but its physical and mechanical properties deteriorate.

摘要

研究了环氧大豆油对基于填充木地板的高密度再生聚乙烯复合材料的操作、工艺以及物理和机械性能的影响。结果表明，向木塑复合材料（WPC）中引入0.5 wt.%的环氧大豆油可改善材料的物理、机械和操作性能：夏比冲击强度（缺口试样）从7.5 kJ/m提高到20.0 kJ/m，弯曲强度从31.6 MPa提高到50.8 MPa，线性热膨胀系数降低15%。随着复合材料中环氧大豆油含量的进一步增加，其吸水率和工艺收缩率降低，但其物理和机械性能恶化。
