Problems solved by technology

[0012] In view of the problems existing in the prior art, the present invention provides a hydrophilic anti-sedimentation far-infrared absorbing material and its preparation method, which can be used in microwave oven products, and aims to solve the problem of microwave absorbing materials used in microwave products. Uneven dispersion of the absorbing agent and easy settlement 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; the use of a large amount of resin materials such as silica gel will cause the absorbing layer to overheat. Thick; does not have far-infrared performance, and the inside of the food is prone to uncooked phenomenon; the production process is complicated, time-consuming and material-consuming; does not have easy-to-clean performance, and long-term use will easily lead to problems such as adhesion of oil stains

Abstract

The invention relates to a hydrophilic type anti-sedimentation far infrared wave-absorbing material and a preparation method thereof. The hydrophilic type anti-sedimentation far infrared wave-absorbing material comprises the following components in parts by weight: 49 to 83.2 parts of a binding agent, 1 to 20 parts of a wave-absorbing agent, 10 to 20 parts of far infrared powder, 5 to 10 parts of an anti-sedimentation agent and 0.8 to 1.5 parts of an additive. During preparation, the components are mixed according to the ratio. The hydrophilic type anti-sedimentation far infrared wave-absorbing material and the preparation method thereof have the advantages of dispersed uniformity of the wave-absorbing agent, insusceptibility to sedimentation, small difference of microwave absorbing property, thin coating, simple production process, time saving and material saving, high hydrophilic performance, insusceptibility to oil dirt adhesion, easiness in cleaning, capabilities of improving the penetrability to food, enabling the food to absorb energy well and improving the cooking effect, and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a hydrophilic 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, which are mixed with binders, solvents, etc. If the agent settles, it will seriously affect the application of the absorbing material, and will also affect the actual absorbing effect of the absorbing material and the stability of temperature rise. 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 effect. [0004] The above-mentioned pr...
