Abstract

The invention discloses a high-temperature-resistant graphene heating plate, which comprises a microcrystalline glass plate, a flaky graphene sintering layer and conductive parts. The flaky graphene sintering layer formed by sintering a flaky graphene mixture is integrally arranged on one side of the microcrystalline glass plate. The two groups of conductive parts which are not in contact with each other are arranged on the surface of the flaky graphene sintering layer. Because the flaky graphene sintering layer fixed on one side of the microcrystalline glass plate after sintering has a stablephysical structure, the structure is very stable, the combination with the microcrystalline glass plate is tighter, and the graphene heating plate is not easy to burst at high temperature. Glue is not used for bonding, and the problem of glue melting at high temperature is avoided. Tests prove that the heating temperature of the graphene heating plate produced by the method can be up to 550-600 DEG C. Compared with the prior art, the heating temperature of the graphene heating plate is greatly improved.

Description

technical field

[0001] The invention relates to the field of heating plates, in particular to 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 heating plate is easy t...
