A kind of coating and its preparation method and application

Abstract

The invention relates to the field of microwave bakeware coatings, and discloses a coating, which contains a microwave-absorbing material and a binder, and the binder is at least one of titanium dioxide sol, silica sol, alumina sol and silica-alumina sol A sort of. The invention also discloses a preparation method of the paint, which includes: mixing the wave-absorbing material and the binder in the presence or absence of auxiliary agents. In addition, the invention discloses the application of the coating in the preparation of microwave baking pans. By using sol as a binder, the dispersion of microwave-absorbing materials can be promoted, so that a thin coating without resin addition, high microwave-absorbing performance and antibacterial performance can be prepared, which is conducive to comprehensively solving the current microwave-absorbing bakeware The problems existing in the material (that is, the use of high temperature is easy to produce harmful substances, poor wave absorption and antibacterial performance, affecting the appearance, etc.), bring better product experience to bakeware users, and make more and more consumers Willing to use the bakeware to bake and grill food at home.

Description

technical field [0001] The present invention relates to a coating and its preparation method and application, in particular to a coating which is especially suitable for microwave bakeware, its preparation method and application. 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 baking pans of existing microwave ovens or microwave ovens mix and disperse the microwave-absorbing powder in the resin, and solidify it on the surface of the metal or ceramic plate through high temperature to form a wave-absorbing layer of about 2 mm, so that the baking pan can absorb microwave energy. The purpose of baking or grilling fo...

AI Technical Summary

Problems solved by technology

[0004] (1) Using a large amount of resin materials, harmful substances are likely to be produced under high temperature conditions, which does not meet the purpose of modern people's pursuit of a healthy life. Moreover, the use of a large amount of resin materials will also affect the conduction of heat, thereby affecting the cooking effect and taste of food;

[0005] (2) It is difficult for microwave-absorbing materials to achieve sheet-like and layered connections, resulting in a decrease in microwave-absorbing performance, and less microwave energy absorbed per unit time, resulting in long cooking time, which does not meet the fast-paced life of modern people;

[0006] (3) It does not have antibacterial function, and long-term use is likely to cause the growth of bacteria and affect the health of users;

[0007] (4) The microwave-absorbing material layer of the microwave baking pan is too thick (about 2 mm), which is not conducive to the appearance design of the product
