Embodiment Construction

[0023] A manufacturing process of a high-temperature-resistant graphene heating plate, comprising the following steps:

[0024] S1. Prepare graphene flakes, carbon crystal powder, additives, catalysts, and glass-ceramic plates;

Abstract

The invention discloses a manufacturing process of a high-temperature-resistant graphene heating plate. The preparation method comprises the following steps: firstly, uniformly mixing flake graphene,carbon crystal powder, an auxiliary agent and a catalyst to form a flake graphene mixture; then uniformly coating a microcrystalline glass plate with the flake graphene mixture to form a sheet-shapedgraphene layer; then putting the sheet-shaped graphene layer into a high-temperature furnace and drying; then, rising the temperature continuously for preheating; rising the temperature to 600 DEG C and performing sintering, so that the flake graphene layer is sintered on the microcrystalline glass plate to form a flake graphene sintered layer; and arranging two groups of conductive parts on the graphene sintered layer so as to be connected with a power supply. Relative to traditional techniques, the structure of the flake graphene sintered layer is more stable, and the graphene heating plateis more tightly combined with the microcrystalline glass plate and is not easy to burst and melt at high temperature, and tests prove that the heating temperature of the graphene heating plate produced by the method can reach 550-600 DEG C. Compared with the prior art, the heating temperature of the graphene heating plate is greatly increased.

Description

technical field [0001] The invention relates to a graphene heating plate, in particular to a manufacturing process of a high-temperature-resistant graphene heating plate. Background technique [0002] The heating plate is a heating method commonly used to heat objects, and graphene is a new heating carrier. It can generate high temperature by energizing the sheet-shaped graphene plate, but due to the cost of the complete sheet-shaped graphene Higher, the manufacturing process adopted by the existing graphene heating plate is to mix the flake graphene powder with a specific glue, and then coat it on a glass-ceramic plate and harden it to make it. However, there is a serious problem in the graphene heating plate produced by this process. The heating temperature of the graphene heating plate can only be heated to 230-300 degrees. After exceeding this temperature, the working state of the graphene heating plate is very unstable, and the glue will In a molten state, the graphene...
