Experimental result is shown in Table 1.
1 detection data of table
It can be seen that compared with existing resin absorbing material baking tray according to the result in table 1, the present invention is using bonding After the mixing of each components such as agent, wave absorbing agent, solvent, sagging inhibitor, far infrared powder and auxiliary agent, while having that coating is thin, and microwave The advantages that performance is good, hydrophilicity is good, anti-settling performance is good, Baking Effect is good and effect easy to clean is good.Embodiment 1 is to implementation The ratio range of example 11 is in " 49~83.2 parts of binder, 1~20 part of wave absorbing agent, 10~20 parts of far infrared powder, sagging inhibitor It, can be by the way that rational proportional region is arranged compared with each comparative example in 5~10 parts, 0.8~1.5 part of auxiliary agent " range One step improves microwave property, hydrophilicity, anti-settling performance, Baking Effect and effect easy to clean etc..Comparative example 1 and right Than embodiment 2 since the far infrared powder of addition is less and sagging inhibitor is more, cause Baking Effect less desirable.Comparison is real Although it is more to apply the far infrared powder that example 3 and comparative example 4 are added, find under study for action, there is no further for coloring effect It improves, and the coating adhesion property prepared can be caused to decline and increase the cost of material.In conclusion " binder 49 The number of~83.2 parts, 1~20 part of wave absorbing agent, 10~20 parts of far infrared powder, 5~10 parts of sagging inhibitor, 0.8~1.5 part of auxiliary agent " It is proper to be worth range.
Embodiment 12 is close with the testing result of embodiment 10, and concrete numerical value is simultaneously unlisted.
The present invention is using one or two kinds of mixing in Ludox, Aluminum sol and silicate solutions (sodium silicate solution, potassium silicate Solution, lithium metasilicate solution) it is used in mixed way as binder, it can make material that there is the material of good combination performance, and with height The heat resistance that temperature is not easily decomposed；It is mixed according to different proportion using one or more of carbon nanotube, silicon nitride, barium titanate Used as absorbing material, main function can very well disperse under the action of suitable adjuvants in a binder, in microwave for addition The material of efficient absorption microwave energy under environment；Use two kinds in silicon carbide, iron oxide, magnesia, zinc oxide, aluminium oxide with On be used in mixed way as far infrared powder, main function, which is the far infrared that sends out, has stronger penetration capacity, can be deeper Layer penetrates food；Using the gentle phase alumina of hydrophilic aerosil as sagging inhibitor, entire coating system can be increased Consistency and filler suspendability, so that coating is had thixotropy, prevent the sedimentation of filler, and can further promote material Hydrophilicity；The compatible mixing very well of each component material can be made using auxiliary agent, and keep coating and base material obtained attached very well The functions such as.
As binder inventor has selected Aluminum sol and silicate to be selected from a kind of on the basis of embodiment 1 again when, He is same as Example 1, can also obtain similar result.
The present invention matches proper amount of dispersant using hydrophilic aerosil, gaseous oxidation aluminium, with other component systems At antiradar coatings so that this coating has excellent anti-settling and uniformity；It solves wave absorbing agent and disperses uneven, Yi Chen Drop, can cause the bulk article microwave absorption difference of same specification and model big, or even can disperse uneven generation because of wave absorbing agent The problem of hot-spot melting phenomenon.
Abandoning tradition baking tray absorbing material of the present invention largely uses the preparation method of organic resin, using with hydrophilicity Aerosil and gaseous oxidation aluminium cooperation high temperature resistant binder and the wave absorbing agent etc. with excellent absorbing property, are made thin 30 μm or so can be reduced to by prior art 2mm or so, greatly reduce suction with the coating of good absorbing property, thickness by applying Wave material thickness solves the prior art and inhales the blocked up disadvantage of wave layer；It avoids and uses the resins such as a large amount of silica gel in the prior art Material causes to inhale the blocked up problem of wave layer.
The present invention compound suitable far-infrared material of addition in absorbing material system, improves the penetrability for food, So that food therein is preferably absorbed energy, realizes the hope of food therein culinary art synchronous with surface layer, it is attached that General Promotion inhales wave microwave The culinary art effect of part；It solves western existing coating and does not have far infrared performance, not yet done problem easily occurs in food therein.
Absorbing material prepared by the present invention only needs simple pretreatment of base material, so that it may to be sprayed on workpiece surface, Coating layer thickness only has 30 μm or so, and compared to more existing traditional absorbing material, technology difficulty is substantially reduced；Solves production technology Complexity takes the problem of taking material.
The present invention, not only can be with by adding hydrophilic aerosil and gaseous oxidation aluminium into absorbing material system It solves the problems, such as that wave absorbing agent is easy sedimentation, the hydrophilicity of material can also be increased, realize quick, the thorough cleaning of greasy dirt.Solution The problem of existing absorbing material technology of having determined is without hydrophilicity, for a long time using the adherency for easily leading to greasy dirt.
