Photovoltaic wiring box body material and preparing method thereof

The invention discloses a photovoltaic wiring box body material. The photovoltaic wiring box body material consists of polybenzyl ether resin, graphene, polystyrene resin, an elastomer, a flame retardant and other auxiliaries. Through the addition of the graphene material into the traditional MPPO (Modified Polyphenylene Oxide), the heat radiatign performance of a wiring box body is improved, and the burnt rate of the wiring box due to poor heat radiation is greatly reduced. Meanwhile, the tenacity and the hardness of the material are improved, and the anti-impact performance of the wiring box is improved.
