Preparation of the composite panels based on non-metallic in waste printed circuit boards

Electrical and electronic products' waste rapid growing caused serious environmental problems.The recycling of waste PCBs had been noticed.The possibility of preparation of the renewable composite panels using non-metallic scraps after air sorting of waste printed circuit boards have been studied and the changes of the tensile strength,bending strength and impact strength of the composite material according to different filler particle size,dosage and modifier has been investigated.The research results showed that using maleic anhydride stem grafting polypropylene(MAH-g-PP) as the modifier,taking polypropylene S700 as the substrate resin,and choosing 20% adding dosage of the 0.125-0.3mm non-metal powder fragments,the plate mechanical properties are superior,and the application prospect is widespread.
