Study on Preparation and Properties of Recycled Plastic-poplar Plywood
In this paper,traditional adhesives were replaced by recycled plastics to make poplar plywood by hot-pressing.The results showed that the amount of recycled plastics made no obvious effects on the bonding strength,and the dry bonding strength reached the maximum with the amount of plastic film of 100g/m2.When the hot temperature was 150℃,the bonding strength no longer increased with the temperature,or even decreased.When the pressing time was 5 minutes,the bonding strength achieved the peak value,and then declined along with the extending of time.After testing,formaldehyde emission was found to be very low or zero.The new plywood is a kind of green and environmentally friendly wood-based panels.Above all,it could be concluded that the amount of plastic film of 100g/m2,the hot pressing temperature of 150℃ and the hot pressing time of 5 minutes were the optimum process conditions in this experiment.
