Further, the implementation method of described here oil product oxidation-resistant material also includes following technical characterictic:
In step 1, described base material is one or more in metal base, inorganic substrate, wood substrate, paper substrates, the textile materials base material.
In the step 1, when the cleaning substrate surface, one of them is cleared up to take following mode, and a carries out grinding process to the surface, and b carries out immersion treatment in the ultrasonic cleaning pond, and c carries out immersion treatment in the corrosion pond that can carry out corrosion treatment to base material.
In step 2, described silver-colored particulate is that yardstick is the nanometer-level silver particle of 10-30 nanometer.
In step 2, the coating method on substrate surface is by in spraying, blade coating, sputter, the dip-coating one of them.
In step 3, described solidification process is realized by carry out heat steaming processing in the steaming room.
In step 3, described solidification process is realized by leaving standstill the solidified mode.
In step 3, described solidification process is that the ultraviolet curing mode that realizes by uviolizing realizes.
The invention has the advantages that: utilize the present invention and supporting implementation method, can slow down the oxidising process of oil product effectively, for edible oil, can be under long hot environment, the quality that still keeps nutrition, health, for technical oils, can make its longer service life.
Embodiment
For example and without limitation, described oil product oxidation-resistant material, its base material part is chosen as metallic material of aluminum.Include silver-colored particulate in the set coating, the yardstick of this silver particulate is the nanometer-level silver particle.And non-limiting, its yardstick is specially the 10-30 nanometer as preferred embodiment, the silver-colored composition of this granularity, and outer surface area is bigger under the situation of unit weight, and result of use is good.
And the coating layer portion Base Material is chosen as existing in the market high-temperature resistant coating.
The implementation method of aforementioned oil product oxidation-resistant material can include following steps:
Step 1 is cleared up the surface of selected base material aluminium.
In addition, selected base material can also be one or more in inorganic substrate, wood substrate, paper substrates, the textile materials base material, as long as can realize the coating of silver-colored composition, just can.
In this step, also need the surface of base material aluminium is handled, so that coating can fix with aluminium matter base material well.
The cleaning mode, can take following mode one of them:
A carries out grinding process to the surface, utilizes this mode the oxide compound and the pollutent of aluminium matter substrate surface can be removed.
B carries out immersion treatment in the ultrasonic cleaning pond.This step can be cleared up the surface contaminant of aluminium matter base material well, but is helpless for the zone of oxidation (being mainly aluminum oxide) on surface.
C carries out immersion treatment in the corrosion pond that can carry out corrosion treatment to base material.In the present embodiment, can adopt acidic solution,, dissolve the aluminum oxide of substrate surface, thereby reach the purpose of surface-conditioning such as the lower hydrochloric acid soln of concentration.
Step 2, the coating that will include silver-colored particulate or silver ions is coated in aforesaid substrate surface.
In this step, will include the coating of 10-30 nanoscale silver particulate, apply at the aluminium matter substrate surface place that had cleared up.Concrete coating method does not limit, and as the implementation of routine and non-limiting, can realize by in the modes such as spraying, blade coating, sputter, dip-coating one of them.
Step 3 is cured aforesaid coating on substrate surface.
Described here solidification process will be according to the composition and the performance of aforementioned coating, and curing environment and deciding, and does not specifically limit.
As typical solidification process for example and non-limiting, one of them in can be in the following way realizes:
A is by carrying out heat and steam to handle and realize steaming in the room.
Such as, can be as required, in 80 degrees centigrade steaming room, heat was steamed 50-80 minute, reached the curing purpose of the top coat on the aluminium matter base material.
B, the solidified mode realizes by leaving standstill.
Such as, can with being provided with the aluminium matter base material of described coating, under 20 degrees centigrade room temperature condition, leave standstill 36-48 hour as required, realize the curing purpose of top coat.
C is cured processing by uviolizing to the ultraviolet curing mode that coating realizes.
Ultraviolet curing is a kind of usual way in the paint solidification, can optionally implement according to the specific performance of coating.
The front is described, and the silver-colored particulate in the coating can also be realized by the material that includes silver ions.Such as, this silver ions can be a silver chloride, silver chloride includes the silver ions composition.
Below the antioxidant effect that the present invention realized is further described.As an example, described oil product is an edible oil.
The oxidizing reaction of edible oil is expressed as follows:
RH+O
2→ROOH
ROOH→RO.+.OH
R.+O
2→ O. chain reaction
ROO.+RH→ROOH+R.
R.+R.→R-R
ROO.+R→ROOR
RH wherein represents the macromole of edible oil, and ROOH represents hydroperoxide.
In the present invention, be catalyst with silver-colored particulate, silver bullion and silver ions, can eliminate free radical R. in the above-mentioned expression formula and the combination of ROO. effectively, thereby prevent further carrying out of polyreaction.
And aforesaid silver bullion, its preferred embodiment and non-limiting can be elected silver thin slice as, because the ductility of silver is extremely strong, so can make as thin as a wafer silver layer, adopts mechanical or chemical mode is fixed in substrate surface and gets final product.
More than be the description of this invention and non-limiting, based on other embodiment of inventive concept, all among protection scope of the present invention.
