Abstract
The utility model relates to an iron-based anti-rust non-sticking cooking utensil, composed of iron-based material, wherein at least one non-stick coating is at least coated on the iron-based material surface, specifically to a ceramic non-stick coating layer. The utility model is characterized in that a transition layer of Fe-N compound layer or metal composite oxide layer is also provided between the iron-based material surface and the non-stick coating. As a transition layer is provided in the utility model, on one hand the transition layer has favorable acid and alkali salt resistance anti-rust performance, on the other hand, it also has good binding force with the surface coating. The utility model has high temperature resistant non-stick performance, but also has favorable acid and alkali salt resistance anti-rust performance, which will not rust after boiling one hour in 5% of sodium carbonate, 3% of acetic acid, and 5% of salt water respectively.
Description
Technical field
The utility model belongs to a kind of cooker, particularly a kind of surface not viscosity good, be difficult for the antirust non-sticking cooking utensils of iron-based that gets rusty again.
Background technology
Iron pan is because its intensity height, advantage such as economical and practical are that China uses the most universal traditional frying pan.But casting iron pan or with the iron sheet pot that steel plate is stamped to form all has easily and gets rusty, easily produces during cooking food shortcomings such as localized hyperthermia and easily sticking pot.In order to overcome the above shortcoming of iron pan, product sold has all been taked following various surface treatment ways in the market: enamel processing is carried out on (1) iron pan surface, though the iron pan case hardness height on enamel surface, wearability are good, the rustless property of acidproof alkali salt might as well, but when food cooking, easily produce localized hyperthermia and easily sticking pot, the crisp porcelain that easily collapses in surface; (2) the iron pan surface is carried out nitriding and oxidizing and is handled, though its case hardness is also higher, wearability might as well, but still easily produce the localized hyperthermia and the easy shortcoming of sticking pot when not overcoming culinary art; (3) the iron pan surface applies processing, because the iron pan surface is easy to generate localized hyperthermia, is not suitable for adopting high temperature resistant non-viscous paints such as polytetrafluoroethylene (PTFE) below 400 degree.And common coating iron pan gets rusty the iron-based material owing to moisture infiltrates from coating micropore to cause coating shedding.Therefore, iron pan oil paint commonly used or organosilicon coating carry out coating processing, because oiliness coating or organic silicon coating do not have micropore, moisture is not easy to penetrate into base material from coating, but its viscosity, high temperature resistant and wearability is all very poor not.
In addition, pot in the electric cooking appliance in the market, its base material is aluminium, stainless steel or aluminium and stainless composite.The coating processing of polytetrafluoroethylene (PTFE) non-viscous paint or pottery non-viscous paint is carried out on the surface of pot usually in the electric cooking appliance, because there is micropore in above two kinds of coatings, if use the iron-based material, so since moisture from coating micropore, infiltrate and the iron-based material got rusty also can cause coating shedding.Therefore, pot in the electric cooking appliance of iron-based material is not used owing to there is shortcoming described above.
In a word, also do not have the good antirust property of acidproof alkali salt in the market, the surface has not viscosity again, and the equal iron-based cooker (comprise electric cooking appliance interior pot) preferably of its hardness, wearability and resistance to elevated temperatures.
Summary of the invention
The purpose of this utility model provides a kind of good antirust property of acidproof alkali salt, and the surface has not viscosity again, and the equal antirust non-sticking cooking utensils of iron-based preferably of its hardness, wearability and resistance to elevated temperatures, to overcome the deficiency of existing iron pan.
To achieve these goals, the utility model is made of the iron-based material, at least be coated with one deck non-sticking lining on iron-based material surface, be characterized in: between the surface of iron-based material and non-sticking lining, also be provided with one deck transition zone, transition zone is the iron-nitrogen compound layer that forms on the base material of iron by gas or bath nitriding technology, or the composite oxide of metal layer that forms on the base material of iron by chemical deposition process.
Above-mentioned non-sticking lining is the pottery non-sticking lining of the above high temperature of anti-400 degree.
Because the utility model is provided with transition zone, transition zone has the rustless property of good acidproof alkali salt on the one hand, and on the other hand, it has good combination power with face coat again.The utlity model has the rustless property of good acidproof alkali salt, respectively with 5% sodium carbonate, 3% acetic acid, 5% salt water boil one hour and can not get rusty.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model is made of the iron-based material, in iron-based material surface-coated one deck pottery non-sticking lining is arranged, and is provided with the transition zone of one deck iron-nitrogen compound layer or composite oxide of metal layer between the surface of iron-based material and pottery non-sticking lining.
The thickness of described transition zone is the 5-40 micron, is preferably the 10-25 micron.
The thickness of described pottery non-sticking lining is the 5-50 micron, is preferably the 20-35 micron.
Embodiment 1:
The utility model at first is as base material 2 with steel plate, with mould molding is frying pan, again after the surface of base material 2 forms the transition zone 1 of one deck iron nitride by gas nitriding technology, respectively apply the non-sticking lining 3 (Fig. 1) of the above high temperature of anti-400 degree of one deck inside and outside again; This resistant to elevated temperatures non-sticking lining is the pottery non-sticking lining.The pottery non-sticking lining is the combination of a kind of burning copolymer and inorganic compound, the above high temperature of its anti-600 degree, and the contact angle that case hardness reaches 6-9H (pencil hardness) and water is the 60-100 degree, is the hydrophobic non-sticking lining of a kind of hard, wear-resistant.
The thickness of the transition zone 1 of present embodiment is the 10-15 micron, and the thickness of pottery non-sticking lining 3 is the 15-25 micron.
Embodiment 2:
The utility model at first is the method with casting, making cast iron is the inner pan of electric cooker of base material 2, blank to pot in the cast iron carries out surface finish with emery wheel, again the surface of base material 2 forms the transition zone 1 of a composite oxide of metal by chemical deposition process after, inner surface at inner pan of electric cooker applies anti-400 degree of one deck pottery non-sticking lining 3 above high temperature, hard, wear-resistant at last, and applies one deck organic silicon coating at the outer surface of inner pan of electric cooker.
The thickness of the transition zone 1 of present embodiment is the 15-20 micron; The thickness of pottery non-sticking lining 3 is the 25-30 micron, and the thickness of organic silicon coating 4 is the 15-25 micron.
