▎ 摘　　要

NOVELTY - The plate has a microcrystalline glass plate that is provided with a heat-conducting insulating layer and a conductive layer. The heat-conducting insulating layer is provided with the conductive layer. The conductive layer is covered with 20-80 m graphene heat emitting layer which is provided with 200-200 m packaging insulating layer. USE - High temperature heating plate of heating device for heating wall heating, heating picture, toilet heating, oven, kitchen heating and drying device. ADVANTAGE - The high temperature heating plate has good structure strength and toughness. The graphene heat layer ensures the timely radiating after heating, improves the heating efficiency, at the same time, the design of the heat conducting insulating layer and the packaging insulating layers ensures the use safety of the high-temperature heating plate. The preparation method is simple and reliable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of high temperature heating plate.
