Embodiment 1

[0035] A pot-shaped non-electromagnetic induction heating container 1, the electromagnetic induction heating area is made on the plane area of ​​the bottom surface of the pot-shaped non-electromagnetic induction heating container 1, firstly, the electromagnetic induction sheet is bonded to the heating part of the heating body through the magnetic induction high temperature resistant environmental protection adhesive, Set the temperature at 60°C in turn, dry for 2-8 hours, set the temperature at 300-600°C, and dry for 2-8 hours.

[0036] Secondly, a protective functional layer is made on the surface of the electromagnetic induction heating area made in the planar area. Protective function layer: sodium silicate water glass 5-50%, kaolin 5-40%, alumina powder 5-30%, quartz powder 5-30%, bentonite 1-20%, calcium stearate 1-20%, Zinc oxide powder 1-20%, white carbon black 1-20%, mica powder 5-40%, potassium methyl silicate liquid 1-5%, color powder 3-20%.

Embodiment 3

[0061] Example 3 First, an ordinary induction cooker was selected, and then magnetic induction high temperature resistant gels and electromagnetic induction sheets with different ratios were prepared, and a ceramic pot was selected as a heating body for comparison of heating efficiency.

[0062] Step 1: Make ten protective functional layers with different proportions.

[0063] Sodium silicate water glass 5-50%, kaolin 5-40%, alumina powder 5-30%, quartz powder 5-30%, bentonite 1-20%, calcium stearate 1-20%, zinc oxide powder 1 -20%, white carbon black 1-20%, mica powder 5-40%, potassium methyl silicate liquid 1-5%, toner 3-20%.

[0064] The first proportioning plan: sodium silicate water glass 50%, kaolin 27%, alumina powder 5%, quartz powder 5%, bentonite 1%, calcium stearate 1%, zinc oxide powder 1%, white carbon black 1 %, mica powder 5%, potassium methyl silicate liquid 1%, toner 3%.

[0065] The second ratio plan: sodium silicate water glass 37%, kaolin 40%, alumina pow...

Abstract

The invention discloses a method for preparing an electromagnetic heating coating, which specifically includes the following steps. Determine the heating part of the heating body, and use the magnetic induction high temperature resistant environmental protection glue to bond the electromagnetic induction sheet to the surface of the heating part. First, adjust the temperature to 50-70°C, and fix it for 2-8 hours; then adjust the temperature to 300-600°C and dry it for 2- 8 hours, dehydration to form an electromagnetic induction heating zone. The protective functional layer is coated on the entire electromagnetic induction sheet by the ceramic coating, and the ceramic coating is coated on the entire electromagnetic induction sheet. First, set the temperature at 70°C to solidify for 2-8 hours; then set the temperature to 120°C and dry at a constant temperature for 0.5-5 hours; Set the temperature at 230°C and dry at a constant temperature for 0.2-5 hours; set the temperature at 300-500°C and dry for 4-8 hours to form a protective functional layer. Under the condition of the same physical environment, the present invention can make the non-electromagnetic induction cookware have good heating efficiency on the common induction cooker.

Description

technical field [0001] The invention belongs to the field of an electromagnetic heating coating preparation method, in particular to an electromagnetic heating coating preparation method. Background technique [0002] An electromagnetic heating coating preparation method is now widely used in household appliances, especially electromagnetic cookers. The existing induction cooker has a very complete technical solution for improving heating efficiency and heating speed. However, the existing induction cooker is very picky about the material of the pot, and some pots of special materials cannot be used, such as ceramic pots, glass pots, stone pots, aluminum pots, copper pots, purple casserole, etc., cannot be directly used on the existing induction cooker. use. This problem is the direction that researchers in the field need to research and develop. Moreover, when the induction cooker is heated with low power, the firepower cannot be continuously and stably heated, and there ...
