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.
