Lyophobic and oleophobic wave absorption 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 use microwave ovens or microwave ovens with baking trays to bake pizza, chicken wings, biscuits and other foods. Therefore, the performance of the baking pan will directly affect the effect, taste and texture of baking and grilling food. [0003] Most of the microwave-absorbing materials used in the baking trays of existing microwave ovens or microwave ovens are microwave-absorbing powder mixed and dispersed in resin, which is solidified on the surface of metal or ceramic disks at high temperatures to form a microwave-absorbing layer of about 2 mm, so as to achieve baking The plate absorbs microwave energy to achieve the purp...

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.
