Problems solved by technology

Graphite products have disadvantages such as poor plastic toughness and low bending strength, which lead to fatal injuries such as broken and bruised graphite products during use. Touching the frying pan will cause damage to the surface of the graphite frying pan, and its service life will be significantly shortened, which limits the application of graphite pots or cooking utensils to high-end rice cookers, electric pressure cookers, frying machines, etc.

Abstract

The invention discloses a preparation process of enamel graphite cookware. The preparation process comprises the following steps: (1) processing graphite into a graphite cookware green body; (2), coating a binder on the surface of the graphite cookware green body uniformly, and then performing high temperature sintering so as to form an intermediate bonding layer on the surface of the graphite cookware green body; and (3), enameling the surface of the intermediate bonding layer so as to obtain the enamel graphite cookware, wherein the binder in the step (2) is a mixed solution which is obtained through uniform mixing of titanium powder or silicon powder or mixed powder of titanium powder and silicon powder, high-purity alcohol, phenolic resin and graphite powder at a mass ratio of 3:4:2:1.The enameling process is applied to the graphite cookware, an enamel layer is formed on the surface of the graphite cookware, and the surface strength of the graphite cookware is improved, so that asurface protective layer is formed, and damage of metal cookware to the graphite cookware is avoided during cooking.

Description

technical field [0001] The invention relates to the technical field of graphite cookware, in particular to a preparation process of enamel graphite cookware and the enamel graphite cookware. Background technique [0002] Graphite has high thermal conductivity, fast heat transfer, uniform heating, and fuel saving. Therefore, baking pans and pots made of graphite are heated quickly, and the baked food is heated evenly, cooked from the inside to the outside, and the heating time is short. Not only the taste is pure, And it can lock the original nutrition of the food. In addition, graphite also has the characteristics of chemical stability and corrosion resistance, as well as health and environmental protection, no radioactive pollution, and high temperature resistance. Therefore, it is especially suitable for preparing some cooking utensils, such as rice cooker, pressure cooker liner, baking pan panel, wok and so on. Graphite products have disadvantages such as poor plastic t...
