Test data
1. microwave property test
Microwave property power uses identical time (2 minutes), identical material and size baking tray, identical microwave oven 100% fire
During power, baking tray maximum temperature characterizes (coating layer thickness the most of the present invention is 30 μm, existing resin absorbing material thickness 2mm).Concrete survey
Examination data are shown in Table 1.
Performance test the most easy to clean
Use soy sauce (light soy sauce): mature vinegar: Saccharum Sinensis Roxb.: edible salt: the mixing of edible oil=3:1:1:1:2 (mass ratio) ratio is all
Even, take 50mL and be added drop-wise to testing sample surface, baking box 220 DEG C baking 20min.By 10N power wet scouring pad wipe samples after cooling
Surface, is excellent with surface without spot.Concrete test data are shown in Table 1.
3. anti-microbial property test
Sterilizing rate performance uses escherichia coli little with the clump count on staphylococcus aureus " 0 " sample time of contact and 24
Time cultivate after clump count ratio on sample.Concrete operation step, with reference to Ministry of Health of the People's Republic of China, " disinfection technology is advised
Model " 2002 years version-2.1.5.3.Concrete test data are shown in Table 1.
4. water contact angle experiment
Utilizing water contact angle tester respectively experimental group and matched group to be carried out water contact angle detection, experimental result is shown in Table 1.
Experimental group uses the baking tray with coating prepared by the material of the embodiment of the present invention 1 to embodiment 8, and coating layer thickness is
30μm；
The thickness of the baking tray of coating prepared by the material of comparative example 1～4 is 30 μm.
Another employing now has the baking tray of coating prepared by resin absorbing material, the thickness of coating be 2mm as a control group.
Contact angle refers to that the tangent line of the liquid-vapor interface made at gas, liquid, solid three-phase intersection point is handed over through liquid with solid-liquid
Angle theta between boundary line, is measuring of wetness degree.If θ < 90 °, then the surface of solids is hydrophilic, i.e. liquid is easier to moistening
Solid, its contact angle is the least, represents that hydrophilicity is the best；If θ > 90 °, then the surface of solids is hydrophobic, i.e. liquid is not easy
Moistening solid, moves the most from the teeth outwards.
Data tested by table 1
Data analysis:
According to the data in table 1 it can be seen that the proportioning of embodiment 1 to embodiment 8 within the scope of the invention, i.e. " is inhaled
Wave material binding agent is 87%～93%, and absorbing material is 6%～12%, and anti-biotic material is 0.5%～1%, and auxiliary agent is 0.5%
～1% ", there is microwave property, bactericidal property, performance easy to clean and the hydrophobic performance of excellence simultaneously, properties is superior to tree
The performance of the baking tray that fat absorbing material is made.
Not within the scope of the invention, the data from table 1 can for the proportioning of comparative example 1 to comparative example 4
The absorbing material going out comparative example 1 and comparative example 2 increases, and absorbing property improves, and corresponding temperature improves, but due to
Filler is too much, and Paint Adhesion can be on the low side, is easily caused coating shedding, and additionally temperature is too high, and time control is bad is easily caused food materials
Carbonization, is harmful to health, and the problem that there is high cost；Although comparative example 3 and comparative example 4 possess the most antibacterial
Performance, but owing to absorbing material is less, absorbing property is poor, and temperature is relatively low.
Inventor, in research process, it has been unexpectedly discovered that, in the case of the holding of other components is constant, absorbing material is
During the mixture of carborundum, zinc oxide, nano-graphite and cerium oxide four kinds, the mass ratio of carborundum and zinc oxide be (3:1)～
(1:3), described carborundum is (1:2.5)～(4:1) with the mass ratio of nano-graphite, and cerium oxide accounts for hydrophobic oleophobic type antibacterial suction ripple
< 0.1%, the performance preparing coating can be more preferably for the mass percent of material.
In sum, technical solutions according to the invention have the advantage that
1) solve suction ripple layer to be resin base, be easily caused greasy dirt and food debris adhesion, not easy cleaning and making for a long time
Problem by unsoundness hidden danger.Present invention employing has the ceramic material binding agent carrier as absorbing material of hydrophobic performance,
Because having hydrophobic, oleophobic performance so that greasy dirt and food debris are difficult to adhesive surface, reach easy cleaning and reduce healthy hidden danger
Purpose.
2) resin heatproof is solved inadequate, the problem i.e. having the risk producing harmful substance at about 280 DEG C.The present invention gets rid of
Abandon tradition baking tray absorbing material and use the preparation method of organic resin in a large number, use and there is hydrophobic, the ceramic material conduct of oleophobic
The binding agent of absorbing material, heat resistance can reach more than 500 DEG C, and can ensure that completely will not be because of high temperature in using environment
Produce unhealthful material, eliminate healthy hidden danger.
3) complex manufacturing, the problem of time-consuming expense material are solved.Absorbing material prepared by the present invention has only to simply
Pretreatment of base material, it is possible to be sprayed on surface of the work, coating layer thickness only has about 30 μm, compares more existing tradition and inhales ripple material
Material, thickness only have its 1/50 to 1/100.
4) problem that existing absorbing material technology does not have anti-microbial property is solved.The present invention is by inhaling to hydrophobic oleophobic type
Wave material system is added the anti-biotic material being suitable for raw material composition, on the basis not affecting hydrophobic oleophobic performance and absorbing property
On, add antibacterial functions, make the material of preparation have suitable anti-microbial property.
