摘要:

以麦秸和废旧聚苯乙烯塑料为原料,采用冷混-热压工艺,通过正交试验和单因子试验,研究热压时间、热压温度、复合材料密度、聚苯乙烯比例和施胶量等工艺参数对麦秸/聚苯乙烯复合材料性能的影响。结果表明:热压时间7min、热压温度190℃、聚苯乙烯比例为35%、施胶量3%、复合材料密度0.6g·cm-3和0.65g·cm-3时,压制出的麦秸/聚苯乙烯复合材料各项物理力学性能指标达到刨花板国家标准(GB/T4897.1-4897.7-2003)要求,确定了试验的最佳工艺参数和工艺条件。

Abstract:

Wheat stalk and recycled polystyrene(PS) were used as raw material to hot press composite. Such as hot-pressing cycle time, density of composite, and ratio of PS to adhesive content, were considered to effect composite properties by orthogonal experimental design and factors. Results showed that those factors made different effects. On the basis of available data, optimized process condition was confirmed: Hot press time of 7 min, hot temperature of 190 ℃, PS proportion of 35%, and the amount of 3%, were a better combination when board density was 0.6 g·cm-3 or 0.65 g·cm-3 ,the resulted composite meet the requirement of national standard.
