Coating as well as preparation method and application thereof

Abstract

The invention relates to the field of microwave ovenware coatings, and discloses a coating which comprises a wave-absorbing material and an adhesive, wherein the adhesive is at least one of titanium dioxide sol, silicon dioxide sol, aluminum oxide sol and silicon-aluminum sol. The invention further discloses a preparation method of the coating. The preparation method comprises the following step: in the presence or absence of an additive, mixing the wave-absorbing material with the adhesive. In addition, the invention discloses an application of the coating in preparing microwave ovenware. As the sol is taken as the adhesive, dispersion of the wave-absorbing material can be improved, a thinly coated layer without resin and an ovenware coating which is good in wave absorbing property and antibacterial property can be prepared, problems (that is, when a conventional ovenware wave-absorbing material is used at a relatively high temperature, harmful substances can be easily generated, the conventional ovenware wave-absorbing property and antibacterial property are poor, the appearance attractiveness can be affected and the like) of the conventional ovenware wave-absorbing material can be comprehensively solved, relatively good product experience can be brought to an ovenware user, and thus more and more customers are willing to make baked and barbecue food by using the ovenware.

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
