Hydrophobic and oleophobic wave-absorbing material and preparation method thereof

Abstract

The invention relates to a lyophobic and oleophobic wave absorption material and a preparation method thereof. The lyophobic and oleophobic wave absorption material is prepared from the following ingredients in percentage by weight: 87 percent to 93 percent of wave absorption material bonding agents with lyophobic and oleophobic performance, 6 percent to 12 percent of wave absorption materials and 0.5 percent to 1 percent of auxiliary agents. During the preparation, all ingredients are uniformly mixed. The lyophobic and oleophobic wave absorption material can be used for coatings of kitchen electric products. The lyophobic and oleophobic wave absorption material has the advantages that the lyophobic performance is good; the cleaning is easy; high temperature resistance is realized; the health and environment protection are realized, and the like.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a hydrophobic and oleophobic wave absorbing material and a preparation method 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, t...

AI Technical Summary

Problems solved by technology

[0004] 1. Because the wave-absorbing layer is resin-based, it is easy to cause oil stains and food residues to adhere, it is not easy to clean, and long-term use may pose health risks;

[0005] 2. The temperature resistance of the resin is not enough, and there is a risk of producing harmful substances at around 220°C;

[0006] 3. The production process of existing absorbing materials is complex, time-consuming and material-consuming

Harmful substances are likely to be produced when used at higher temperatures, and cleaning is difficult, which largely affects the application of bakeware-type microwave-absorbing materials in microwave ovens and microwave ovens.
