  Wave absorbers used in the microwave industry are generally high-density ferrites, carbides, nitrides, and the like, and are mixed with a binder, a solvent, and the like to produce a wave-absorbing material. It is very easy for the absorbent to settle, which has a great effect on the application of the wave absorbing material, further affects the actual wave absorbing effect and the temperature rising stability of the wave absorbing material, and also increases the temperature. It is well known that this can result in overuse, which can lead to safety issues in use.

In the conventional microwave industry, the wave absorbing material technology mainly consists of adding a high-density wave absorbing agent to a silica gel binder, adding an appropriate amount of an auxiliary agent, etc., mechanically stirring, mechanically stirring, vulcanizing and cross-linking to about 2 mm. The final wave-absorbing sheet is formed by pressing on a silica gel wave-absorbing sheet, and the wave-absorbing sheet is further adhered to the surface of the base material via an adhesive to produce a microwave absorbing accessory. However, microwave hot plates made by such a method have the following disadvantages:

The same roasting time (3 min) is set in a far-infrared enamel oven having each (the enamel oven in the prior art is the same as the far-infrared enamel oven except that the hot plate is different), After roasting the toast for 3 minutes, the coloring on the surface of the toast is uniform, and the properties and the colored area are determined. The experimental results are shown in Table 1.

  As can be seen from the results shown in Table 1, as compared with the conventional resin wave absorbing material hot plate, the present invention mixed each component such as a binder, a wave absorber, a solvent, an anti-settling agent, a far-infrared powder and an auxiliary agent. After that, the coating layer is thin, has good microwave properties, has good hydrophilic properties, has good anti-settling properties, has good roasting effects, and has good cleansing effects. . The compounding ratio ranges in Examples 1 to 11 are all “binder 49 to 83.2 parts, wave absorber 1 to 20 parts, far infrared powder 10 to 20 parts, anti-settling agent 5 to 10 parts, auxiliary agent. 0.8 to 1.5 parts ", compared with each comparative example, by setting an appropriate ratio range, microwave characteristics, hydrophilic characteristics, anti-settling characteristics, roasting effect and cleanliness The effect that is easy to achieve can be further improved. In Comparative Example 1 and Comparative Example 2, the amount of far-infrared powder added was small and the amount of the anti-settling agent was large, so that the roasting effect was not so favorable. In Comparative Example 3 and Comparative Example 4, although a large amount of far-infrared powder was added, the investigation revealed that the coloring effect was not further improved, the adhesion of the produced coating layer was reduced, and the cost of the material was increased. Was found. As described above, “49 to 83.2 parts of binder, 1 to 20 parts of wave absorber, 10 to 20 parts of far-infrared powder, 5 to 10 parts of anti-settling agent, 0.8 to 1.5 parts of auxiliary” The numerical range is compatible.

  The results of Example 12 and Example 10 are close and do not show specific values.

  The present invention provides a material having good bonding characteristics by using one or two mixtures of silica sol and aluminum sol with a silicate solution (sodium silicate solution, potassium silicate solution, lithium silicate solution) and using the mixture as a binder. And has a temperature resistance that is not easily decomposed at high temperatures, and one or more of carbon nanotubes, silicon nitride, and barium titanate are mixed at different ratios, and added as a wave absorbing material. It is a material that disperses well in the binder by the action of appropriate auxiliaries and efficiently absorbs microwave energy in a microwave environment. It is a mixture of two or more of silicon carbide, iron oxide, magnesium oxide, zinc oxide, and alumina. Used as far-infrared powder, its main function is that the emitted far-infrared has strong transmission ability and can penetrate deeper into food By using hydrophilic gas-phase silica and gas-phase alumina as anti-settling agents, the consistency of the entire coating system and the suspension characteristics of the filler are improved, and the coating has thixotropic properties and can prevent the sedimentation of the filler. And the hydrophilic property of the material can be further configured. By using the auxiliary agent, each component material can be well compatible and mixed, and the produced paint can be well adhered to the base material. It has the function of

  Based on Example 1, the inventor performed the same as Example 1, except that one selected from aluminum sol and silicate was used as the binder, and obtained similar results.

  The present invention uses hydrophilic gas-phase silica and gas-phase alumina, mixes an appropriate amount of a dispersing agent, produces a wave absorbing coating with other components, and imparts excellent anti-settling property and uniformity to the coating. However, the solution wave absorbing agent is non-uniformly dispersed and easily settles, and mass-produced products of the same specification type have a large difference in microwave absorption characteristics, and the wave absorbing agent is non-uniformly dispersed, thereby locally The problem that even the phenomenon of overheating and melting occurs is solved.

  The present invention abandons the conventional manufacturing method in which a hot plate wave absorbing material uses a large amount of organic resin, and uses a gas phase silica and a gas phase alumina having a hydrophilic property and a high temperature resistant binder and a wave absorption having an excellent wave absorbing property. A coating material with good wave absorption characteristics even if it is applied thinly is manufactured by blending agents and the like, and the thickness is reduced from about 2 mm of the prior art to about 30 μm, and the thickness of the wave absorption material is significantly reduced. The problem that the wave absorbing layer is too thick due to the use of a large amount of resin material such as silica gel in the prior art was avoided.

  In the present invention, an appropriate amount of far-infrared ray material is added to the wave-absorbing material system to improve the permeability to the food, absorb the energy inside the food better, and simultaneously cook the inside of the food and the surface layer. The demand was fulfilled, the cooking effect of the wave absorbing microwave accessory was improved overall, and the conventional coating layer did not have the far-infrared characteristics, and the problem of boiling inside the food was easily solved.

  The wave absorbing material manufactured according to the present invention can be pretreated with a simple base material and sprayed on a work surface, and the thickness of the coating layer is as thin as about 30 μm. The difficulty was significantly reduced, the production process was complicated, and the problem of labor and materials was solved.

  The present invention not only solves the problem that the wave absorber easily precipitates by adding hydrophilic gas-phase silica and gas-phase alumina to the wave-absorbing material system, but also improves the hydrophilic property of the material and makes oil stains faster. Thorough cleaning can also be realized. The conventional wave-absorbing material technology can solve the problem that it has no hydrophilic property and is likely to stick to oil stains due to long-term use.
