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 280°C;
[0006] 3. The production process of existing absorbing materials is complex, time-consuming and material-consuming;
[0007] 4. Does not have antibacterial properties
It is easy to produce harmful substances when used at a higher temperature, and it is difficult to clean and easy to produce bacteria, which largely affects the application of baking pan-type microwave-absorbing materials in microwave ovens and microwave ovens.

Abstract

The invention relates to a hydrophobic and oleophobic antibacterial wave-absorbing material. The hydrophobic and oleophobic antibacterial wave-absorbing material is prepared from, by mass, 87% to 93% of wave-absorbing material adhesive, 6% to 12% of wave absorbing material, 0.5% to 1% of antibacterial material and 0.5% to 1% of additive. The wave-absorbing material adhesive is a hydrophobic and oleophobic material. In the preparation process, all the components are mixed to be uniform. The hydrophobic and oleophobic antibacterial wave-absorbing material can be applied to kitchen electric products, and has the advantages of being easy to wash, free of potential health danger, good in temperature-resisting performance, simple in production process, good in antibacterial performance and wave-absorbing performance, saving time and materials 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 antibacterial 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 ac...
