Problems solved by technology

[0012] In view of the problems existing in the prior art, the present invention provides a hydrophobic anti-sedimentation far-infrared absorbing material and its preparation method, which can be used in kitchen appliances, especially in microwave products, aiming to solve the existing problems The absorbing agent of the microwave absorbing material for microwave products is unevenly dispersed and easy to settle, which will lead to large differences in the microwave absorbing performance of batch products of the same specification and model, and even local overheating and melting due to uneven dispersion of the absorbing agent; use a large amount of silica gel Such as resin materials, resulting in too thick absorbing layer; without far-infrared performance, the inside of the food is prone to uncooked phenomenon; the production process is complicated, time-consuming and material-consuming; it does not have hydrophobic properties, and long-term use may easily lead to the adhesion of oil stains, etc. question

Abstract

The invention relates to a hydrophobic anti-settling far-infrared wave-absorbing material and a preparation method thereof. The hydrophobic anti-settling far-infrared wave-absorbing material comprises, by weight, 52 to 80 parts of a binder, 0.5 to 2 parts of a wave-absorbing agent, 10 to 20 parts of far-infrared powder, 5 to 10 parts of a solvent, 1 to 15 parts of an anti-settling agent and 0.8 to 1.5 parts of an auxiliary agent. In preparation, the above ingredients are mixed together in a proportion. The hydrophobic anti-settling far-infrared wave-absorbing material has the advantages of good wave absorbing effect, good far-infrared radiation performances, good taste of a cooked food, good settling resistance and hydrophobic and easy-cleaning performances.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a hydrophobic anti-sedimentation far-infrared wave-absorbing material and a preparation method thereof. Background technique [0002] As we all know, most of the absorbing agents used in the microwave industry are ferrites, carbides, nitrides, etc. with high density. These compounds are mixed with binders, solvents, etc. The sedimentation of the wave absorbing agent will seriously affect the application of the wave absorbing material, and will also affect the actual wave absorbing effect and temperature rise stability of the wave absorbing material. It is more likely that the temperature will be too high, and there will be safety problems in use. [0003] In addition, related microwave appliances made of microwave-absorbing materials tend to overcook the surface of the food while the inside of the food is not yet cooked, which affects the consumer experience and actual cooking e...
