Easy-to-clean coating with high microwave absorbing property as well as preparation method and application thereof

Abstract

The invention relates to an easy-to-clean coating with high microwave absorbing property as well as a preparation method and an application thereof. The easy-to-clean coating with high microwave absorbing property comprises 10-40wt% of microwave absorbing material binder, 5-10wt% of microwave absorbing material, 50-80wt% of hydrophilic easy-to-clean material and 1-2wt% of auxiliary. In preparation, all raw materials are proportionally mixed together. The easy-to-clean coating with high microwave absorbing property provided by the invention can be widely applied to kitchen electric products and has the properties such as thin coating, high microwave absorbing property and easiness in cleaning.

Description

Technical field [0001] The invention relates to a paint, in particular to a paint with high wave absorbing performance and easy to clean, a preparation method and application thereof. Background technique [0002] With the improvement of people's living standards and the rapid improvement of food health requirements, more and more families are baking pizza, chicken wings, biscuits and other foods by using microwave ovens or microwave ovens with baking trays. Therefore, the performance of the bakeware will directly affect the effect, taste and taste of the baked and grilled food. [0003] The absorbing materials used in the baking trays of the existing microwave ovens or microwave ovens mostly mix and disperse absorbing powders in resin, and solidify on the surface of the metal or ceramic trays at high temperature to form an absorbing layer of about 2 mm to achieve baking. The tray absorbs microwave energy to achieve the purpose of baking and grilling food. However, the microwave ...

AI Technical Summary

Problems solved by technology

[0004] 1. Using a large amount of resin materials, harmful substances are likely to be produced under high temperature conditions, which does not meet the purpose of modern people's pursuit of a healthy life;

[0005] 2. The microwave absorbing material layer of the microwave baking pan is too thick (due to the limitation of the material, generally about 2mm), which is not conducive to the design of the product appearance, and a large amount of resin material is used, which affects the conduction of heat, thus affecting the cooking effect of food and taste;

[0006] 3. It is necessary to disperse the wave-absorbing powder in the resin-based material to achieve the adhesion of the wave-absorbing material, so that the wave-absorbing material cannot be connected in sheets or layers, resulting in a decrease in wave-absorbing performance and absorbing microwaves per unit time Less energy leads to long cooking time, which cannot meet the fast-paced life of modern people;

[0007] 4. Ferrite is often used as the absorbing material. In most cases, the absorbing performance of this material is not satisfactory in the microwave environment;

[0008] 5. It does not have the function of easy cleaning. After the user bakes, there is a lot of oil on the surface, which is difficult to clean.

It is easy to produce harmful substances, slow heat conduction, poor microwave absorption performance, and affect the appearance when used at higher temperatures, which largely affects the application of bakeware microwave-absorbing materials in microwave ovens and microwave ovens.
