A kind of wave-absorbing material for ceramics, preparation method and application thereof

Abstract

The invention relates to an absorbing material for ceramics, a preparation method and application of the absorbing material for ceramics. The absorbing material for ceramics comprises the following components in percentages by mass: a binding agent 80%-90%, an absorbing material 3%-6%, electromagnetic shielding powder 5%-15%, and an auxiliary agent 0.5%-1%. During preparation, the various components except the electromagnetic shielding powder are mixed together in proportion, then are added with the electromagnetic shielding powder, and are mixed evenly to obtain the absorbing material for ceramics. By reasonable proportioning of the various components, the problems that a wave absorbing layer of an existing microwave accessory product is thick, a resin matrix is used at high temperature, health is affected, wave absorbing performance is poor, and water loss is severe when the absorbing material is used for ceramic products are solved, ceramic materials can be widely used in microwave products, the wave absorbing performance can be improved remarkably, water loss and dryness of food materials are prevented effectively, production cost is reduced, and use experiences of consumers are improved.

Description

technical field [0001] The invention relates to a coating, in particular to a wave-absorbing material for ceramics, 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 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] Ceramic utensils are recognized by consumers as healthy cooking utensils, and the taste and texture of ingredients cooked by ceramic utensils are much better than traditional ordinary cooking utensils (metal and plastic, etc.), so they are recognized by consumers. In the industry, there is no relevant technical support for the microwave absorption performance of ceramic material utensils. The main reason is that compa...

Problems solved by technology

[0011] In view of the existing problems in the prior art, such as easy generation of harmful substances, slow heat conduction, poor microwave absorption performance, and aesthetic impact, the present invention provides a microwave-absorbing material for ceramics, which solves the problem of the existing microwave accessories through a reasonable ratio of components. The microwave-absorbing layer of such products is thick, the use of resin-based high temperature affects health, the microwave-absorbing performance is poor, and the application of ceramic products has serious water loss problems. The wide application of ceramic materials in microwave products has significantly improved the microwave-absorbing performance and effectively prevented Food materials lose water and become dry, which reduces production costs and improves consumer experience
