NOVELTY - The utility model claims a heat-resistant toughening modified plastic, comprising a polyimide plastic base layer, a glass fibre layer set on the upper surface of the polyimide plastic base layer, a graphene layer set on the lower surface of the polyimide plastic base layer, a first aluminium foil layer set on the outer surface of the glass fibre layer, a second aluminium foil layer set on the outer surface of the graphene layer, and a neopentyl glycol phase change radiating layer set on the outer surface of the first aluminium foil layer and the second aluminium foil layer; the outer surface of the neopentyl glycol phase change radiating layer is provided with multiple reinforcing ribs. Compared with the existing technology, the utility model is set with high strength and toughness of the glass fibre layer and graphene layer, at the same time, it also through the double layer of the first aluminium foil layer and the second aluminium foil layer is set, so that the plastic has high toughness; by setting the neopentyl glycol phase change radiating layer, ensuring good heat-resistant performance of the plastic; Therefore, the plastic provided by the utility model has good heat-resistant performance and toughness.
