Problems solved by technology

[0005] 2. Thick wave-absorbing patches affect the appearance design of cooking utensils and the aesthetics of products
The resulting problem: the thickness of the wave-absorbing sheet is not conducive to the appearance design of the product, nor is it conducive to the user experience
Especially for some baking pans with special shapes or structures, thicker coatings cannot meet the needs of use
If the coating is thicker, problems such as poor adhesion, low strength, and high cost will also occur

Abstract

The invention relates to a wave absorbing coating and a preparation method thereof. The wave absorbing coating is prepared from, in percentage by mass, 88%-98% of a wave absorbing material adhesive, 1%-10% of a wave absorbing material and 0.5%-2% of an aid. During preparation, all components are mixed in proportion. The wave absorbing coating has the advantages of thin coating, good adhesion capability, high strength, good heat conducting property, low cost and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a wave-absorbing coating and a preparation method thereof. Background technique [0002] With the gradual change of diet structure, people are more and more inclined to use microwave ovens to cook food. Pizza, barbecue, and baked food are among the more popular foods. If you want to achieve good color, crispness, and taste, etc. Requirements, the absorbing material for cooking utensils is a key factor. [0003] Most of the microwave-absorbing materials used in the baking trays of existing microwave ovens or microwave ovens are to mix and disperse the microwave-absorbing powder in the resin, and solidify it on the surface of the metal or ceramic plate through high temperature to form a layer of microwave-absorbing material of about 2 mm, so as to achieve The baking pan absorbs microwave energy to achieve the purpose of baking and grilling food. However, the microwave baking pan...
