Background technology
Increasingly raising with people's living standard and the rapid raising for food health requirements, more and more families
Front yard bakes the foods such as Pizza, chicken wings, biscuit by using micro-wave oven or microwave oven cooperation baking tray.Therefore, the performance of baking tray will
It will have a direct impact on baking, the effect of food roasting, taste and mouthfeel.
The absorbing material that the baking tray of existing micro-wave oven or microwave oven uses mostly is that will inhale the mixing of wave powder to be dispersed in
In resin, by hot setting in metal or ceramic panel surface, 2 millimeters or so of suction wave layer is formed, is inhaled to reach baking tray
It receives microwave energy and realizes the purpose for baking, roasting for food.But Microwave roasting plate made of the method has the following disadvantages：
1. because it is resin base to inhale wave layer, easily leads to greasy dirt and adhered to swill, easy cleaning, unstrong using having for a long time
Health hidden danger；
2. resin heatproof is inadequate, there is the risk for generating harmful substance at 220 DEG C or so；
3. the production technology of existing absorbing material is complicated, takes and take material.
If above-mentioned cleaning and health safety issues can be solved, it will largely improving the existing user for inhaling wave baking tray makes
With experience and healthy quality.
Currently, either microwave oven is added with the also rarely seen use of baking tray without resin (or low resin), is hydrophobic thin micro-wave oven
Easy clean, absorbing property coating the report of oil.The absorbing material of micro-wave oven or microwave oven baking tray is also all only confined in use
The high thickness of resin base (2 millimeters or so), traditional absorbing property material (ferrite etc.), without performance materials easy to clean.In higher temperatures
The problems such as lower use of degree is also easy to produce harmful substance, cleaning is difficult, largely affects baking tray class absorbing material product and exists
Application on micro-wave oven and microwave oven.Therefore, it is very to prepare the Microwave roasting plate class coating with hydrophobic type absorbing property
It is necessary！

30μm；
(thickness of coating is the baking tray for the coating that control group is respectively prepared with resin absorbing material in the prior art
2mm), the baking tray that comparative example 1-4 makes (thickness of coating is 30 μm).
Multiplicating experiment is carried out, and carries out statistical analysis, laboratory test results are shown in Table 1.It can be seen that according to table 1
The clean-up performance for the baking tray that the embodiment of the present invention 1 makes to embodiment 6 is better than existing resin absorbing material baking tray.
1 testing result of table
By data above it can be seen that：
With existing resin absorbing material baking tray (temperature is 175 DEG C, and water contact angle is 83 DEG C, clean-up performance rank difference) phase
Than the temperature of embodiment 1 to embodiment 6 is 241-252 DEG C, water contact angle is 108-146 °, clean-up performance grade is excellent, is had
The advantages that temperature is high, hydrophobic performance is good and clean-up performance is good.
Embodiment 1 is to embodiment 5 using hydrophobic oleophobic type ceramic material as absorbing material binder, the use of embodiment 6
The mixture of silicon dioxide gel and TiO 2 sol can be seen as absorbing material binder according to the testing result of table 1
Go out, the hydrophobic performance of the coating of the coating preparation prepared using hydrophobic oleophobic type ceramic material wants better.
Comparative example 1 and comparative example 4 are using hydrophobic oleophobic type ceramic material as absorbing material binder
But each group distribution ratio is not at " absorbing material binder 87%~93%, absorbing material 6%~12% and auxiliary agent 0.5%~1% "
Technical solution in range.Comparative example 1 is can be seen that from the data in table 1 and 2 temperature of comparative example is increased and still dredged
Water degradation, comparative example 1 and 2 hydrophobic performance of comparative example improve but temperature reduces.Meet " absorbing material binder
87%~93%, the technical solution in 0.5%~1% " range of absorbing material 6%~12% and auxiliary agent can be taken into account hydrophobic simultaneously
Performance, temperature and performance easy to clean.
Inventor have also been attempted in the course of the research in silicon carbide, zinc oxide, nano-graphite and cerium oxide one kind or
Two kinds of mixing finds performance of the performance better than coating made of resin absorbing material of coating obtained as absorbing material.
In conclusion the invention has the advantages that：
1) it solves that inhale wave layer be resin base, easily leads to greasy dirt and swill and adhere to, not easy cleaning, for a long time using having
The problem of healthy hidden danger.The present invention uses bonding agent carrier of the ceramic coating with hydrophobic performance as absorbing material, because of tool
There is hydrophobic, oleophobic performance so that greasy dirt and swill are not easy adhesive surface, reach easy cleaning and reduce the mesh of healthy hidden danger
's.
2) it solves that resin heatproof is inadequate, has the risk for leading to the problem of harmful substance at 220 DEG C or so.The present invention is got rid of
The preparation method that traditional baking tray absorbing material largely uses organic resin is abandoned, using with hydrophobic, oleophobic ceramic material conduct
The binder of absorbing material, heat resistance even can reach 500 DEG C or more, and can ensure completely in use environment will not be because
High temperature has an impact the substance of health, eliminates healthy hidden danger；
3) the problems such as production technology is complicated, the expense of taking is expected is solved.Absorbing material prepared by the present invention only needs simply
Pretreatment of base material, so that it may which to be sprayed on workpiece surface, coating layer thickness only has 30 μm or so, inhales wave material compared to more existing tradition
Material, thickness only have its 1/50 to 1/100.
In addition to the hydrophobic oleophobic type ceramic material that the present invention describes, other groups with high temperature resistant, hydrophobic oleophobic characteristic
If similar performance can also be realized by dividing, these components are also within the scope of the present invention.
In addition to the absorbing material that describes of the present invention, if other components with high absorbing property can also realize it is similar
Performance, then these components are also within the scope of the present invention.
In addition to the auxiliary agent that the present invention describes, if other may be implemented to increase attachment, levelling, defoaming, suspension thickening power
Auxiliary agent can also prepare this material, then these auxiliary agents are also within the scope of the present invention.
Adjustment for step of preparation process of the present invention and mixing speed, if similar performance can also be realized,
Also within the scope of the present invention.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
