Description

[Technical Field]

[0001] The present invention relates to the field of cooking utensils, and in particular to non-stick metalware and non-stick pans. , which significantly improves the non-stick effect of metalware. [Background technology]

[0002] Conventional non-stick pans generally have a layer of anti-stick coating on the inner wall of the pan. The most commonly used coating material is Teflon, whose scientific name is , polytetrafluoroethylene, which solves the problem of sticking to the pan well, It brings convenience to people's lives. However, the anti-stick coating on the inner wall of the pot During use, the anti-stick coating is easily removed, especially when cooked at high temperatures. If the pan is heated empty, it will be more likely to cause the non-stick coating to fall off. Polytetrafluoroethylene itself is non-toxic, but if the pan is heated at high temperature or left unheated, When placed in a location where the temperature is too high, polytetrafluoroethylene will carbonize, split, and release trace amounts of toxic It releases gases and substances that contaminate the food being cooked and cause the food to burn. This can cause problems such as galling and ingesting chemical coatings.

[0003] On this basis, non-stick pans have appeared in the prior art, which utilize the lotus effect. The anti-sticking structure is made on the inner wall of the pot by using a porcelain sintered material. The size of the protrusions and depressions is from several microns to several tens of microns. The inner wall surface of the nonstick pot changes to a rough surface with micron-order roughness. This changes the contact surface between the food being cooked and the inner surface of the nonstick pan into a composite contact surface. The gas is adsorbed in the recessed areas between the protrusions of the anti-adhesion structure and in the recessed areas of the depressions. This creates an air bed layer that prevents the food from coming into contact with the inner surface of the nonstick pan. Effectively reduces the contact area, prevents food from burning, prevents physical sticking, and has zero coating Zero coating nonstick, even when frying at high temperatures or when the pan is empty The pot does not release any toxic substances or gases, contaminating the food being cooked and the kitchen environment. This allows for safer cooking.

[0004] However, this structure is applied to the surface of a non-stick pan, creating a physical non-stick layer. Forming is still not enough. When using a non-stick pan, you need to heat it. Therefore, the air bed layer formed in the recessed area described in the above solution will not break down in a heated environment. This destroys the physical non-stick properties and defeats the purpose.

[0005] However, simply installing the physical non-stick method on the surface of the pot will not provide long-lasting results. It is not enough to achieve perfect non-stick, so the pot and shovel will Since it needs to be rubbed against the surface of the pot repeatedly, prolonged friction can cause physical damage to the nonstick surface. This will wear down the non-stick layer and prevent the non-stick effect from lasting longer. The issue is also waiting for a prompt solution.

[0021] Hereinafter, several embodiments of the present invention will be described in detail in conjunction with the drawings. Unless conflicting, the features in the following embodiments can be combined with each other.

[0022] Example 1: The non-viscous metal article 100 shown in FIGS. 1 to 6 includes a first metal layer 101 and a second metal layer 102. The first metal layer 101 is configured as an inner layer, and the inner surface of the first metal layer 101 is The surface is roughened to the micron order with pores on the micron order. The polished surface is formed by sandblasting, preferably by multi-stage sandblasting. In other embodiments, knurling may be employed. A PVD multi-component metal film 104 is plated on the micron-order roughened surface, and the PVD multi-component metal film 1 04 Micro-nanometer order pores are distributed on the surface, forming a porous oil lock structure. The first metal layer 101 and the second metal layer 102 are integrally compounded with a heat-soaking layer 103 interposed therebetween. The heat spreader layer 103 has a higher thermal conductivity than the first metal layer 101, and This prevents localized areas of 101 from becoming too hot and damaging the PVD multi-metal film 104.

[0023] Physical Vapor Deposition (PVD) technology is a method of converting the surface of a material source (solid or liquid) into gaseous atoms or molecules by using physical methods under vacuum conditions. or partially ionized into ions and then subjected to a low-pressure gas (or plasma) process. Physical vapor deposition refers to the technology of depositing a film with special functions on the surface of a body. It is one of the main surface treatment technologies. PVD (Physical Vapor Deposition) film plating technology is Mainly vacuum evaporation film plating, vacuum sputtering film plating and vacuum ion film The main methods of physical vapor deposition are vacuum deposition, sputtering, and plating. Film plating, arc plasma film plating, ion film plating and molecular beam epitaxy The applicable vacuum film plating equipment is a vacuum evaporation film plating machine. , including vacuum sputtering film plating machine and vacuum ion film plating machine. Due to the difference in the PVD (Physical Vapor Deposition) film plating technology, it is further developed into tool plating and equipment plating. In order to ensure the thickness of the PVD multi-metal film, the present application By using the plating method, the PVD multi-metal film can reach 0.7~4.0 microns. Preferably, the thickness of the PVD multi-metal film is 1.0 to 2.5 microns. Specifically, the thickness of the PVD multi-metal film is 2.0 microns, and in another embodiment In some cases, it may be 3 or 4 microns. The thickness of the metal film should be compatible with the micron-order roughened surface, and the thickness of the PVD metal film should be in the order of microns. The Rz value of the PVD metal film must be smaller than that of the chronologically roughened surface. It adheres to the micro-roughened surface and forms a micro-nano-order porous oil-lock structure. It can be formed without covering the micron-order roughened surface, and in this application, The meter-order porous oil-lock structure is formed on the basis of the micron-order roughened surface. can be.

[0024] Furthermore, the micro-nanometer porous oil lock structure is a multi-metallic alloy (containing at least chromium and aluminum, and also titanium, copper, and iron) Nitrides, carbides and oxides (which may contain Deposited on the micron-order roughened surface, micron-order pores are further formed, and The nanopore diameter is in the range of 0.1 to 3.0 microns, and in this embodiment, it is 0.1 to 1.0 microns. The specific size of the micron-order holes was measured using a Zeiss microscope. It can be measured by Axioplan 2imaging (model number) and is in the nanometer order. The pore sizes were measured using a Nova 400 scanning electron microscope from FEI (USA). It can be measured using NanoSEM (model no.).

[0025] In one preferred embodiment, the useful life of the PVD plating layer 104 is further extended. Therefore, the non-adhesive metal article adopts a steel-aluminum-steel composite structure, where the first metal layer 101 is a stainless steel layer, the heat-soaking layer 103 is an aluminum layer, and the second metal layer 102 is a stainless steel layer, for example, SUS430. The stainless steel to be selected is Most preferably, the first metal layer 101 is food grade, for example, SUS304. The second metal layer 102 mainly serves a protective function and may be made of metals other than stainless steel, e.g. For example, titanium alloy may be selected. To do this, first, a plurality of etching recesses are etched in an array on the inner surface, and then the sample is The grooves may be formed by chemical etching or laser etching. It may be manufactured by using a technique such as knurling or embossing. The grooves are then etched to form a micron-order roughened surface. , a lotus structure can be formed inside the inviscid metal object 100, thereby forming a nonce Improves tick effect.

[0026] In this example, the micro-nanopores contract and expand as the temperature changes when heated. You can use animal fat or vegetable oil to heat and maintain the pan. The nanopores expand as the temperature of the pot body increases and contract as the temperature of the pot body decreases. He further explained that when the user heats the pot body, the micro-nano pores expand, allowing oil and fat to enter and exit. When the heating of the pot body is stopped, the temperature of the pot body will gradually cool down, The chromopores contract and when the oil enters the holes, it is locked in, providing an oil locking function. This also ensures that the non-stick properties of the surface of the pan are maintained. The micro-nanopores with a width of 0.1 to 1 μm have good oil storage and oil locking properties. This improves the non-stick effect of the pan surface. The specific drawing is shown in Figure 3. Micro-nano porous structure of PVD multi-metal film in the present invention After storing oil, the hydrophobic contact angle can reach 95 or more, This gives the present invention an excellent non-stick effect.

[0027] In this example, the PVD multi-metal film contains primarily titanium, chromium, and aluminum. Here, the chromium content is 20 to 50 at %, and the aluminum content is 50 The titanium content is 1 to 10 at%. When the content is between 1 and 10 at%, the surface energy can be effectively reduced. The anti-sticking effect is improved by the above. Preferably, the content of titanium element is 3 to 6 at%. Specifically, the content of titanium element may be 3 at %. The aluminum element contained in the film can reduce its surface energy, The anti-sticking effect is improved by the addition of aluminum, and the aluminum content is preferably about 30 at %. The chromium element contained in the coating not only reduces the surface energy but also The chromium content is preferably 0.1 to 100% by weight, and more preferably 0.2 to 100% by weight. The PVD multi-metal film is composed of a bottom layer and an intermediate layer, which are deposited in order from bottom to top. and a surface layer. The bottom layer contains metallic titanium and / or metallic chromium, Titanium and chromium are both present in metallic form, which is why PVD multi-metal films and roughened surfaces are and also to remove heavy metal substances from the first metal layer. It is also important to note that the precipitation of chlorine can prevent the body from affecting its health. In the bottom layer, titanium and chromium may be present alone or together; Both can achieve the purpose of preventing adhesion and heavy metal deposition, but titanium and chromium At the same time, the performance is better.

[0028] In the intermediate layer, the nitride and / or carbide containing chromium aluminum is titanium nitride. Specifically, titanium nitride (TiN), chromium nitride (CrN), and / or carbides may be included. Aluminum nitride (CrN), aluminum nitride (AlN), titanium carbide (TiC), chromium carbide (Cr C), aluminum carbide (AlC), aluminum titanium nitride (AlTiN) and aluminum nitride Aluminum chromium nitride (AlCrN), aluminum titanium nitride (AlTiN), aluminum nitride Aluminum chromium (AlCrN) and aluminum chromium carbide (Cr2AlC) may also be used. The specific content of the multi-metallic compound can be adjusted by a person skilled in the art within the above range. It should be noted that chromium aluminum nitrides and carbides may exist independently. In particular, chromium carbide contributes to the hardness and wear resistance of the PVD multi-metallic coating, as well as It can significantly improve the corrosion resistance and corrosion resistance of PVD multi-metal films. In another embodiment, chromium carbide can be added to the surface layer. It can further improve the hydrophobicity of PVD multi-metal films. Aluminum nitride has good thermal stability and good thermal shock resistance, and aluminum nitride has a ceramic-like It has excellent thermal conductivity and prevents the PVD film from being destroyed by excessive heat in certain areas. Chromium nitride has good corrosion resistance and reduces the friction coefficient of the PVD film. This reduces the wear and tear and provides excellent wear resistance. The combination of aluminum nitride and carbide has higher hardness and wear resistance. In addition, the intermediate layer further provides the PVD film of the present invention with good mechanical and thermal shock resistance. It can also be used when cooking with tools such as metal shovels. In this embodiment, the PVD multi-element alloy is not easily destroyed when the local area is too hot. Metallic films have low surface energy and extremely high hardness and non-stick properties. Specifically, its hardness can reach HV1000-5000, and the surface energy The flow rate can reach 40 dynes or less, and the drop angle is 95 degrees or more.

[0029] Specifically, in this embodiment, the interlayer contains chromium nitride and aluminum nitride, Here, the content of chromium nitride is 60 to 80 wt%, specifically 75 wt%. Here, the content of aluminum nitride is 20 to 40 wt%, specifically 25 wt In another embodiment, the intermediate layer comprises chromium carbide, wherein the content of chromium carbide is is 85 to 95 wt%, and the other components are one of aluminum nitride and titanium nitride. Or a combination of the two, which may further include an ingredient such as aluminum carbide. The surface layer contains metallic copper and aluminum oxide, and the content of the metallic copper is 1.0 to The surface layer further contains iron oxide, and the surface layer is 10 wt %, specifically 5 wt %. The iron oxide is 3 to 15 wt%, specifically 10 wt%, and further 5 wt% or 1 The surface layer may be made of metallic copper and aluminum oxide. Except for aluminum and iron oxide, the content of other elements and impurities is less than 5 wt%.

[0030] In this embodiment, the PVD film is a non-viscous metal film containing chromium and aluminum as main elements. The aluminum element contained in the PVD multi-metal film reduces its surface energy. The chromium content can be reduced, thereby improving the anti-sticking effect. Not only can it reduce surface energy, but it can also improve corrosion resistance. In the PVD multi-metal film of this embodiment, the main metals are The components are titanium, aluminum, chromium, iron and copper, and the non-metallic components are mainly oxygen and carbon. It contains silicon, nitrogen, and silicon.

[0031] The surface layer may further comprise oxides of titanium and chromium, specifically titanium and chromium. One of the oxides, for example titanium oxide, or a combination of titanium oxide and chromium oxide The combination of metallic copper and aluminum oxide (metallic copper and aluminum oxide) may contain at least The combination of aluminum iron oxide gives the surface good non-stick properties. The surface layer can form a layer of oxide on the surface of the PVD film, which prevents subsequent use. This prevents color change problems during the process. At the same time, aluminum oxide is This can prevent the formation of toxic copper oxide due to oxidation of copper.

[0032] By increasing the amount of metallic copper in the PVD multi-metallic film, the PVD multi-metallic film has antibacterial properties. When the copper content is 10 wt% or less, the PVD multi-metal film The anti-sticking effect can be improved.

[0033] In this example, the bottom layer is attached on the micron-order roughened surface, and the surface layer is attached on the surface of the intermediate layer. The thickness of the surface and bottom layers is relatively small, specifically, both are 0.1 In this embodiment, it is 0.3 μm or less, and in other embodiments, it is 0.5 μm or less. The thickness of the intermediate layer is 5 to 6.8 μm, and specifically is 6.4 μm.

[0034] The inner surface of the PVD multi-metal film 104 is a polished surface, for example, by using high-pressure water to polish or The thickness of the PVD multi-metal film 104 is in the range of 0.7 to 6.0 μm. Preferably, the thickness of the PVD multi-metal film 104 is in the range of 2 to 5 μm. The thickness range of the D multi-metal film 104 is 2 μm.

[0035] Based on the above technical content, the purpose is to construct a porous oil lock structure with low surface energy. Those skilled in the art can adjust the proportions of various components according to actual needs, and the above multi-component On the basis of the metal, other metal or non-metallic components can be added, for example, silicon element can be further added. The hardness range of the PVD multi-metal film 104 is as follows: The hardness range of the PVD multi-component metal film 104 is HV 1000 to 5000. The hardness is 1100 to 3500, and more preferably HV2000 to 3500. VD multi-metallic films have relatively low surface energy, but their hardness and wear resistance are extremely high. Therefore, the present invention has good anti-sticking effect, high hardness and abrasion resistance. This has the beneficial effects of providing good durability and a long service life.

[0036] In this embodiment, the wear resistance of the PVD multi-metal film 104 is in accordance with the Chinese national standard GB / T32 095.2~2015 Non-stick surface performance and test standard for household metal food cookware Part 2: After 5,000 wear resistance tests in accordance with the "Non-stick and Wear Resistance Test Standards" In this case, the egg frying test can be carried out without oil and the non-stick property can be achieved as Class I. refers to using a plastic shovel to remove the eggs without damaging them and leaving no residue behind. Grade II eggs cannot be removed without damaging them using a plastic shovel, This means that the residue can be removed by wiping lightly with a wet sponge or cloth. The non-stick performance of the non-stick metalware 100 of the present invention is Class I. After the test, the results showed that the first-class eggs could reach 7-9, with the best record being 20. It reaches first-class eggs and far exceeds the requirements of the Chinese standard for three eggs.

In order to control the thickness of the PVD multi-metal film 104, the multi-metal film 104 is deposited on a micron-order roughened surface. The micron-order pores can be made to micro-nanometer-order pores. This allows the inner metal surface to have a good non-stick effect. During the process, the bottom of the pot is likely to be too hot locally, causing the PVD multi-metal film 4, causing the pot to lose its non-stick properties. In order to solve this technical problem, The pot adopts an aluminum heat-equalizing layer 103 between the two layers of metal, The aluminum heat-equalizing layer 103 allows the bottom of the pot to receive heat more uniformly, thereby This will extend the nonstick life of your pan.
