Hydrophilic antibacterial water absorption material and preparation method thereof

Abstract

The invention relates to a hydrophilic antibacterial water absorption material and a preparation method thereof. The hydrophilic antibacterial water absorption material is prepared from, by mass, 90%-97% of water absorption material inorganic adhesive, 2%-8% of water absorption material, 0.5%-1% of antibacterial material and 0.5%-1.5% of additive. The water absorption material inorganic adhesive is a hydrophilic inorganic material. In the preparation process, all the components are mixed to be uniform. The hydrophilic antibacterial water absorption material can be applied to kitchen electrical products and has the advantages of being easy to clean, free of potential health hazards, good in temperature resistance, simple in production process and good in antibacterial performance and wave absorption 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 hydrophilic 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 achieve the purpo...

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 280°C

[0006] 3. The production process of the existing microwave-absorbing materials is complicated, time-consuming and material-consuming. At present, it is rare to use a coating with no resin (or low resin) added, hydrophilic and easy to clean, and microwave-absorbing properties for baking trays used in microwave ovens or microwave ovens. ; The microwave-absorbing materials for microwave ovens or baking trays for microwave ovens are only limited to the use of resin-based high-thickness (about 2 mm), traditional microwave-absorbing materials (ferrite, etc.), and no easy-to-clean performance materials.

[0007] 4. Does not have antibacterial properties

[0008] It is easy to produce harmful substances, difficult to clean, easy to produce bacteria and other problems when used at higher temperatures, which largely affects the application of baking pan-type microwave-absorbing materials in microwave ovens and microwave ovens.
