Description
Technical Field
The invention relates to the technical field of cookware, in particular to a preparation method of a non-stick cookware and the non-stick cookware prepared by the preparation method.
Background
Most of non-stick cookers sold in the current market are PTFE (polytetrafluoroethylene) coating non-stick cookers, the highest temperature resistance of the PTFE (polytetrafluoroethylene) coating cannot exceed 250 ℃, and the non-stick performance of the PTFE coating cannot be rapidly attenuated and rapidly carbonized and shed after the temperature exceeds 250 ℃, so that the problems of short service life, no dry burning resistance, easiness in shedding and the like of the coating exist, and a large amount of metal materials are wasted in China every year. And even if the paint is not damaged, the paint is slowly worn by food, and finally, the paint is completely eaten by a human body along with dishes, so that the service life of the product is influenced, and the health of the human body is endangered.
A bionic lotus leaf non-stick pan also exists in the market, the inner surface of the bionic lotus leaf non-stick pan imitates a micro-nano structure of lotus leaves with mastoid, the contact area between food and the pan bottom is reduced, and a physical non-stick barrier is established. The bionic lotus leaf non-stick pan mastoid structure in the related art is insufficient in hardness, cannot resist scraping and rubbing of an iron shovel or high temperature, and cannot keep the anti-sticking performance of the bionic lotus leaf non-stick pan mastoid structure for a long time.
Disclosure of Invention
The present invention aims to solve one of the technical problems in the related art to a certain extent. Therefore, the invention provides a preparation method of the non-stick pan, which has the advantage of long service life of the prepared non-stick pan.
In order to achieve the above purpose, the invention adopts the following technical scheme:
the preparation method of the non-stick pan comprises the following steps:
s101, selecting a pot base body;
s102, preparing a composite material, wherein the composite material comprises a first binding phase for increasing strength, a second binding phase for assisting in increasing strength and a high-carbon compound;
s103, processing the composite material to the inner surface of the matrix to form a composite material layer;
s104, heating the substrate to carbonize the high carbon compound to form a plurality of holes and peaks;
s105, fusing the composite material layer to passivate peaks to form mastoid structures.
In the invention, a composite material layer with a bionic lotus leaf structure is processed on the inner surface of a pot base body, and the bionic lotus leaf structure is a concave-convex shape with a mastoid structure. The composite material layer is in direct contact with food, so that the contact area between the food and the cooker is reduced, and the cooker can achieve the effect of nonstick cooking. It should be noted that, the inner surface of the pan base is defined as the surface that should be in direct contact with food, the mastoid structure is also formed on the surface of the composite material layer that is in direct contact with food, and the other surface of the composite material layer is attached to the inner surface of the pan.
The composite material comprises a first binding phase, a second binding phase and a high-carbon compound, and is processed to the inner surface of the matrix to form a composite material layer. The composite material contains high carbon compounds, and when the inner surface of the matrix is heated, the high carbon compounds are carbonized and become brittle, so that a cavity structure with low surface energy is formed. The cavity structure is of course distributed on the inner surface of the composite material layer (i.e. the surface directly contacted with food), and the inner surface of the composite material layer presents uneven microscopic appearance with cavities and peaks, so that the contact area of the food and the cooker is reduced, and the sticking of the cooker is prevented. In addition, the cavity structure can absorb air and store grease, hot air and oil mist can be generated in the heating process, food can be supported, and meanwhile, the contact area between the food and the cooker is reduced by the cavity structure, so that the effect of physical non-adhesion is achieved.
The inner surface of the composite material layer is fused, and sharp peaks are passivated to form compact arc-shaped particles, namely mastoid structures, and the free energy of the surface of the particles is reduced. And after the melting, the hardness of the peak is improved, so that the composite material layer is more resistant to the scraping and rubbing of the turner, and the service life of the cooker is prolonged.
Optionally, the composite layer is fused by plasma or laser to deactivate peaks, and the mastoid structure hardness formed after the fusing is 800-1200 HV. And the inner surface of the composite material layer is fused by adopting a plasma beam or a laser beam with high energy density, and the peak of the inner surface is passivated to form a mastoid structure, so that the surface energy of the inner surface is reduced, and the non-sticking effect is improved. The mastoid structure hardness formed after high-energy fusing is improved to 800-1200 HV.
Optionally, in step S102, the carbonization temperature of the selected high carbon compound is lower than 600 ℃. In the present invention, it is desirable to add a high carbon compound to the composite material in order to facilitate subsequent carbonization of the high carbon compound and formation of voids in the composite material layer. The selection of the high carbon compound with lower carbonization temperature can enable the composite material layer to form holes at a relatively low temperature, which is beneficial to improving efficiency and saving energy.
Optionally, in step S104, the inner surface of the substrate is carbonized by heating for a period of 0.5 to 1 hour. The matrix is maintained above the carbonization temperature of the high carbon compound for 0.5 to 1 hour, so as to form a cavity structure with low surface energy.
Optionally, the composite material comprises the following components in percentage by mass: 40-70% of a first binding phase, 15-50% of a second binding phase and 5-10% of a high-carbon compound. The first binder phase in the composite material has the greatest mass ratio for reinforcing the hardness and binding other substances in the composite material, and also for binding the composite material to the pan substrate. The second bonding phase is used for assisting the bonding of the first bonding phase, further enhancing the bonding degree between the materials and enabling the composite material layer to be connected with the matrix more firmly. The high carbon compound is used for carbonizing the matrix after heating to form cavities and peaks.
Optionally, the first binder phase is one or more of titanium, titanium alloy, zirconium alloy, molybdenum alloy, hafnium alloy, and stainless steel. The first binding phase is high-hardness high-strength metal and provides a certain strength for the composite material layer, so that the composite material layer is more wear-resistant, and can be kept clean for a long time under high temperature or high-strength scraping. The composite material layer is not easy to fall off when the cooker is subjected to high-temperature cooking.
Optionally, the second binding phase is one or more of silicate, diatomite, silicon oxide and titanium oxide. The second binder phase can assist in reinforcing the hardness of the composite layer, improving scratch resistance. And silicate and diatomite have lower melting points, and can form a porous structure at a high temperature higher than the melting points, thereby being beneficial to grease penetration.
Optionally, the high carbon compound is one or more of acrylic resin, stearic acid, fatty acid, starch and fiber. The carbonization temperature of the acrylic resin is 200-300 ℃, and stearic acid is decomposed above 200 ℃. After carbonization of the acrylic or stearic acid, the composite layer forms a multi-hole structure.
Optionally, in step S102, when preparing the composite material, the first binder phase, the second binder phase and the high carbon compound are dispersed, ground and mixed uniformly, and then granulated to obtain particles with a particle size of 100-450 meshes. And (3) putting the first binding phase, the second binding phase and the high-carbon compound into a dispersion grinder for dispersion grinding, and uniformly mixing the first binding phase, the second binding phase and the high-carbon compound so that cavities formed after carbonization of the follow-up high-carbon compound are uniformly distributed in the composite material layer. The composite material after dispersion grinding is made into particles with the particle size of 100 to 450 meshes by a granulator.
Optionally, in step S103, the particles of the composite material having the particle size of 100 to 450 mesh are processed to the inner surface of the substrate by thermal spraying, plasma spraying, cold spraying or laser cladding, so as to form a composite metal layer. The composite material prepared by dispersing, grinding and uniformly mixing the first binding phase, the second binding phase and the high-carbon compound is suitable for being processed to the inner surface of a substrate by adopting a thermal spraying mode, a plasma spraying mode, a cold spraying mode or a laser cladding mode.
Optionally, in step S102, when preparing the composite material, the first binder phase, the second binder phase, and the high carbon compound are configured into a core-in-core structure; wherein the first binding phase forms a crust, and the second binding phase and the high carbon compound are filled into the crust after being dispersed, ground and granulated. And carrying out dispersion grinding and granulation on the second binding phase and the high carbon compound, and filling the mixture into the outer skin formed by the first binding phase to form the core-spun structure.
