摘要
在室温恒定的情况下,主要研究了原材料配比、材料制备工艺参数在不同载荷条件下对木塑复合材料24 h蠕变性能的影响。结果表明,在24 h蠕变试验中各载荷下影响蠕变量的优势因素各不相同,但木塑比都为第一显著因素;载荷为30%弯曲强度时,木塑比与螺杆转速为显著因素;载荷为50%弯曲强度时,木塑比为显著因素;载荷为70%弯曲强度时,只有木塑比为极显著因素。
The effects of raw material ratio and process parameters and material preparation process parameters on the 24 h creep properties of PEbased woodplastic composites at different loads and constant room temperature.The results indicated that the wood/plastic ratio was the first significant factor,although there are different superior factors on the creep variable of the composites during the 24 h creep tests.Furthermore,the wood plastic ratio and the rotation speed of the screw are significant factors at the load of 30%bending strength,and the wood/plastic ratio was the significant factor at the load of 50%bending strength.However,only the wood/plastic ratio became the most significant factor at the load of 70%bending strength.
