Embodiment 1

[0020] Example 1 Electromagnetic induction heating paint

[0021] The electromagnetic induction heating paint, its components and mass percentages are:

[0022] Silver hydroxide 28.4%

[0023] Silver Oxide 25.2%

[0024] Nickel oxide 0.5%

[0025] Glass powder 4.1%

[0026] Binder 41.8%

[0027] Above-mentioned glass powder, its composition is trilead tetraoxide 85%, silicon oxide 7.5%, boron oxide 7.5%.

[0028] Above-mentioned binding agent, its component is ethyl cellulose 16%, terpineol 85%.

Embodiment 2

[0029] Example 2 Preparation method of electromagnetic induction heating coating

[0030] The preparation method of the electromagnetic induction heating paint comprises the steps of raw material pretreatment, weighing, ball milling and mixing in sequence.

[0031] The raw material pretreatment process is to dry the silver hydroxide, silver oxide, nickel oxide, and glass powder in an oven for 1.5 hours at a temperature of 70-80° C. to remove the moisture therein for later use.

[0032] The process of weighing materials is to weigh various raw materials with a balance according to the mass ratio of raw materials according to the production quantity, and then put them into a ball mill jar.

[0033] The ball milling process is to add ball mill seeds in the tank and continue rolling ball mill for 80 hours.

[0034] The mixing and stirring process is that the rolled and ground materials are put into a ceramic stirring container, and then the binder is added and stirred for 1.5 hou...

Abstract

The electromagnetic inducing heating paint consists of silver hydroxide 28.4 wt%, silver oxide 25.2 wt%, nickel oxide 0.5 wt%, glass powder 4.1 wt% and adhesive 41.8 wt%. The preparation process of electromagnetic inducing heating paint includes successive material pre-treatment, weighing, ball milling and mixing. After the electromagnetic inducing heating paint is painted onto the surface of ceramic or glass utensil and high temperature sintered, film is formed and attached firmly. The film is induced to heat in electromagnetic furnace, and compared with heating metal material, the film of the present invention has certain heat insulating function. During use, the electromagnetic inducing heating paint has no denaturation and falling off.

Description

technical field [0001] The invention relates to a paint compound characterized by its physical properties or the sintered coating effect produced and a preparation method thereof, in particular to an electromagnetic induction heating paint and a preparation method thereof. Background technique [0002] Nowadays, induction cookers have been widely used, and non-magnetic pots and pans such as ceramics and glass can be used on induction cookers after special treatment. As disclosed by the Patent Office CN1448453A about electromagnetic induction heating paint and its preparation method, it is formed by coating the heating paint on the outer surface of the non-magnetic pot and then sintering it. The layer is easy to change color and oxidize, and the manufacturing process is complicated. Contents of the invention [0003] In order to make up for the above-mentioned defects in the prior art, the present invention proposes a new ele...
