Description
Technical Field
The present invention relates to the field of cookware, and more particularly, to a composite material, a method of making the composite material, and a non-stick cookware sprayed with the composite material.
Background
The existing non-stick product for the pot is generally formed by spraying fluororesin coating on the surface of a metal substrate of the pot, so that the non-stick effect is achieved, but the problem of short service life of the existing non-stick product made of fluororesin is mainly embodied in the following aspects:
1. is easy to be scratched: because the fluororesin is a high polymer material and has lower hardness, when the fluororesin non-stick product is coated on the surface of a pot and hard food (such as shells and the like) is stir-fried by using the pot, the surface of the pot is easy to scratch, so that the service life of the fluororesin product is shorter;
2. easy falling: because the metal substrate of pan is sand blasting, its roughness is less, and after using a period, the cohesion between fluororesin non-stick layer and the metal substrate descends because of long-term expend with heat and contract with cold, leads to droing of fluororesin non-stick layer even in the use.
Disclosure of Invention
An object of the present invention is to provide a composite material having a pore structure due to inclusion of a pore material, and thus having non-tackiness; in addition, the composite material has good strength and good bonding force with the surface of the pot due to the inclusion of the spray coating material.
Another object of the present invention is to provide a non-stick cookware, which is made of composite material sprayed on the surface of cookware to obtain a non-stick cookware with durable non-stick effect.
According to an aspect of the present invention, there is provided a composite material including a spray material and a pore material disposed on an outer surface of the spray material, the spray material including at least one of a metal material and a metal compound-containing material, and the pore material including one or more of zeolite, bentonite, diatomaceous earth, silicate, cordierite, aluminum titanate, and aluminosilicate. The pore material has more fine pores, so that on one hand, the oil can be stored, and the oil-storing non-adhesiveness is provided; on the other hand, the surface of the pore is of a micro-rough structure, and a non-sticky and non-adhesive structure similar to lotus leaves can be provided. The metal material can provide good bonding force with the surface of the cookware, and the metal compound-containing material can improve the hardness of the composite material.
In an embodiment, the metallic material may include one or more of titanium, titanium alloy, iron, stainless steel, low carbon steel, high carbon steel, cast iron, copper alloy, aluminum alloy, nickel, and nickel alloy, and the metal-containing compound material may include one or more of titanium oxide, titanium nitride, titanium carbide, triiron tetroxide, iron oxide, ferrous oxide, aluminum oxide, chromium oxide, and nickel oxide. The metal material can provide good bonding force with the surface of the cookware, and the metal compound-containing material can improve the hardness of the composite material.
In an embodiment, the composite material may further include a binder adhering the void material to the outer surface of the spray material, wherein the composite material includes 50 wt% to 80 wt% of the spray material, 1 wt% to 2 wt% of the binder, and the balance of the void material, based on the total weight of the composite material. When the respective materials of the composite material are within the above content ranges, the composite material has good non-tackiness.
In an embodiment, the binder may comprise an alcohol binder and/or a cellulose binder, wherein the alcohol binder comprises polyvinyl alcohol and/or polypropylene alcohol, and wherein the cellulose binder comprises hydroxymethyl cellulose, hydroxyethyl cellulose, and/or hydroxypropyl methyl cellulose. The alcohol binder and/or the cellulose binder have good binding performance, and can enable the pore materials to be well adhered to the surface of the spraying material.
In an embodiment, the particle size of the spray material may be greater than the particle size of the pore material. Since more pore material needs to be adhered to the surface of the spray material to meet the proportion requirement of the pore material in the composite material, the particle size of the pore material is preferably smaller than that of the spray material.
According to another aspect of the present invention, there is provided a method of preparing a composite material for non-stick cookware, the method comprising the steps of: preparing a spraying material and a pore material; preparing a spraying material and a pore material into slurry; spray drying the slurry to form powder particles; sintering the powder particles to obtain a composite material with a pore material disposed on the spray material, wherein the spray material comprises at least one of a metal material and a metal-containing compound material, and the pore material comprises one or more of zeolite, bentonite, diatomaceous earth, silicate, cordierite, aluminum titanate, and aluminosilicate. The composite material prepared by the method has good non-adhesiveness, high strength and bonding force with the surface of a pot.
In an embodiment, in the step of preparing the slurry, the spray material and the pore material are mixed into a solution to prepare a slurry having a solid content of 20 wt% to 70 wt%, wherein the solution includes 1 wt% to 4 wt% of a binder, 0.5 wt% to 1 wt% of a dispersant, 1 wt% to 2 wt% of an antifoaming agent, and the balance of water, based on the total weight of the solution. The binder enables the pore material to be well adhered to the surface of the spraying material; the dispersing agent can prevent the sedimentation and the coagulation of the spraying material and the pore material, so that the spraying material and the pore material are suspended in the solution to form stable slurry; the defoaming agent can inhibit the foaming property of the slurry and make the slurry uniform and stable.
In an embodiment, the binder comprises hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, polyvinyl alcohol and/or polypropylene alcohol; the dispersant comprises citric acid and/or triethyl hexyl phosphoric acid; the defoaming agent comprises polyether modified silicone oil and/or organic silicone oil. The binder enables the pore material to be well adhered to the surface of the spraying material; the dispersing agent can prevent the sedimentation and the coagulation of the spraying material and the pore material, so that the spraying material and the pore material are suspended in the solution to form stable slurry; the defoaming agent can inhibit the foaming property of the slurry and make the slurry uniform and stable.
In an embodiment, the spray drying is performed at 6000 rpm to 15000 rpm and at a temperature of 100 ℃ to 400 ℃. The composite material prepared under the process condition has good non-stickiness.
According to yet another aspect of the present invention, there is provided a non-stick pan comprising a substrate and a non-stick coating sprayed on the substrate, the non-stick coating comprising a composite material. The non-stick pan has a lasting non-stick effect.
The composite material of the present invention has a pore structure due to the inclusion of the pore material, and thus has non-tackiness; in addition, the composite material has good strength and good bonding force with the surface of the pot due to the inclusion of the spray coating material. The non-stick cookware with lasting non-stick effect can be obtained by spraying the composite material on the surface of the cookware.
Drawings
The above and/or other features and aspects of the present invention will become apparent and appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings.
FIG. 1 is a flow diagram illustrating the preparation of a composite material according to an embodiment of the invention.
Detailed Description
The embodiments are described below in order to explain the present invention by referring to the figures. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The pore material has more fine pores, so that on one hand, the oil can be stored, and the oil-storing non-adhesiveness is provided; on the other hand, the surface of the pore is of a micro-rough structure, and a non-sticky and non-adhesive structure similar to lotus leaves can be provided. However, since the pore material is generally an inorganic material formed under long-term natural conditions, the pore material cannot be directly prepared into the non-stick coating through related processes, and therefore the pore material needs to be modified to form the non-stick coating.
Due to the nature of the porous material, the porous material cannot be sprayed directly, and it is granulated with other materials (e.g., spray material) before spraying. The pore spraying granulation material is obtained by mainly granulating the pore material and the spraying material, and the surface of the non-stick coating formed by the material through cold and hot spraying has uniform and fine pores, so that the non-stick coating can store oil well in the daily use process, and finally good non-stick property is provided.
The composite material according to the present invention includes a spray material and a void material disposed (specifically, adhered) on an outer surface of the spray material.
The spray material includes at least one of a metal material and a metal compound-containing material.
The metal material may include one or more of titanium, titanium alloy, iron, stainless steel, low carbon steel, high carbon steel, cast iron, copper alloy, aluminum alloy, nickel, and nickel alloy, and the metal-containing compound material may include one or more of titanium oxide, titanium nitride, titanium carbide, ferroferric oxide, iron oxide, ferrous oxide, aluminum oxide, chromium oxide, and nickel oxide. The metal material has the main functions of improving the binding force with the base material of the cookware and preventing the non-stick coating from falling off. The metal compound-containing material has good strength, can prevent the non-stick coating from being scratched, and prolongs the service life of the non-stick coating.
The porous material may include one or more of zeolite, bentonite, diatomaceous earth, silicates (e.g., high siliceous silicates), cordierite, aluminum titanate, and aluminosilicates.
The pore material and the spraying material are granulated to form the pore spraying granulated material, the pore spraying granulated material can form a non-stick coating through cold and hot spraying, and the formed non-stick coating keeps a pore structure and a surface rough structure in the original pore material.
In an embodiment of the present invention, a composite material may include a metallic material and a porous material adhered to an outer surface of the metallic material. The composite material has good non-adhesiveness and bonding force with the cookware base material.
In an embodiment of the present invention, a composite material may include a metal compound-containing material and a pore material adhered to an outer surface of the metal compound-containing material. The composite material has good non-stick property and strength.
In embodiments of the invention, the composite material may include both a metal material and a metal-containing compound material and a pore material adhered to an outer surface of the metal material and the metal-containing compound material. The composite material has good non-adhesiveness, strength and binding force with the cookware base material.
In one embodiment of the invention, the composite material may further include a binder that adheres the porous material to the outer surface of the spray material.
The composite material comprises 50-80 wt% of spraying material, 1-2 wt% of binder and the balance of pore material based on the total weight of the composite material.
The pore material is adhered to the surface of the spraying material through the adhesive, when the proportion of the spraying material is more than 80 wt%, the non-adhesion is poor, and when the proportion of the spraying material is less than 50 wt%, the proportion of the pore material is high, and finally the bonding force between the non-stick coating and the cookware base material is poor.
The binder may include a higher alcohol-based binder and/or a cellulose-based binder. The higher alcohol based binder may include polyvinyl alcohol and/or polypropylene alcohol, and the cellulose based binder may include hydroxymethyl cellulose, hydroxyethyl cellulose and/or hydroxypropyl methyl cellulose.
In one embodiment of the present invention, in order to adhere much pore material to the spray material, preferably, the particle size of the spray material may be larger than that of the pore material. Specifically, the particle size of the spray material may be 10 to 40 μm, and the particle size of the porous material may be 1 to 10 μm.
The particle size of the spray material may be 10 to 40 μm, for example, 15 to 35 μm, 20 to 30 μm, or 15 to 20 μm. When the particle size of the spray material is less than 10 μm, the particle size of the composite material is small in the finally prepared composite material (for example, pore spray granulated powder), resulting in clogging of the powder feeding pipe; when the particle size of the spray material is larger than 40 μm, the surface roughness of the formed non-stick coating is large and the appearance is poor, and the required spray power is large, which results in high production cost.
The particle size of the porous material may be 1 μm to 10 μm. When the particle size of the pore material is smaller than 1 mu m, the proportion requirement of the pore material in the composite material can be met only by adsorbing more pore materials on the surface of the spraying material, so that the granulation cost is higher; when the particle size of the porous material is larger than 10 μm, the particle size of the porous material is larger, the smaller the proportion of the porous material adhered to the spray material is, and the adhesion cost is higher.
The particle size of the composite material may be 20 μm to 100 μm. When the particle size of the composite material is less than 20 micrometers, a powder feeding pipe in a spraying matching device in the spraying process is easy to block, so that the production is not smooth; when the particle size of the composite material is more than 100 mu m, the granulation yield is low, the cost is high, and the production control is not facilitated.
Hereinafter, a method of preparing the composite material will be described with reference to fig. 1.
Referring to fig. 1, the method of preparing a composite material according to the present invention includes: a step S100 of preparing a spray material and a pore material; a step S200 of preparing a slurry from the spraying material and the pore material; a step S300 of spray-drying the slurry to form powder particles; and a step S400 of sintering the powder particles.
In step S100, the raw materials of the spray material and the pore material used may refer to the raw materials of the spray material and the pore material described above. The spray material and the pore material may be ground to a predetermined particle size by means of grinding, for example, the particle size of the spray material may be ground to 10 μm to 40 μm, and the particle size of the pore material may be ground to 1 μm to 10 μm. In addition, in the grinding process, the particle size of the obtained spraying material is as same as possible, and the particle size of the obtained pore material is as same as possible, so that the subsequent processes of pulping, spraying and the like are facilitated.
In step S200, a spray material and a pore material are mixed into a solution to prepare a slurry with a solid content of 20 wt% to 70 wt%, wherein the solution may include 1 wt% to 4 wt% of a binder, 0.5 wt% to 1 wt% of a dispersant, 1 wt% to 2 wt% of an antifoaming agent, and the balance being deionized water, based on the total weight of the solution. The proportion of the dispersing agent to the defoaming agent is in direct proportion to the proportion of the binder, and the higher the content of the binder is, the higher the content of the dispersing agent to the defoaming agent is. Because the particle size of the powder particles is smaller, the smaller the particle size of the powder particles with the same mass, the larger the surface area of the powder particles, more binding agent is needed, and the binding agent accounts for 1-2 wt% of the finally obtained granulated powder. In step S200, when the weight ratio of the binder is less than 1 wt%, the binder is less, and thus the composite material cannot be effectively granulated, and when the weight ratio of the binder is greater than 4 wt%, the binder is higher, which easily causes agglomeration after subsequent spray sintering, and thus reduces the production efficiency.
The adhesive may refer to the adhesive described above. The dispersant may be a commonly used dispersant, for example, including citric acid and/or triethylhexylphosphoric acid, and the defoaming agent may be a commonly used defoaming agent, for example, including polyether-modified silicone oil and/or silicone oil.
And mixing the spraying material and the pore material with the solution to finally obtain the slurry with the solid content of 20-70 wt%. In the slurry, the more the liquid part content, the less the solid content, but when the solid content is less than 20 wt%, the granulation time is long and the cost is high; when the solid content is more than 70 wt%, the solid content is high, and the liquid content in the slurry is low, so that the subsequent spraying process cannot be stably carried out, and the production stability is influenced.
In step S300, the slurry is conveyed to a high-speed liquid-throwing disc with 6000-15000 r/min (for example, 6000-12000 r/min) to form liquid drops, the liquid drops are blown into a drying tower with 100-400 ℃ by hot air with 60-100 ℃, and the liquid drops form spherical and solid powder particles after 5-15 seconds in the descending process. Since the original powder particles (i.e., the spray material and the porous material) have a relatively small particle size, the powder particles after the binder is adhered to the powder particles are relatively small in size, and thus can be thrown out at a relatively low rotational speed (e.g., 6000-.
In step S400, the spray-dried powder particles are sintered to remove moisture in the powder particles. The sintering curve is prepared according to the physical properties of the raw material powder, and the temperature rise rate is generally 5 to 20 degrees centigrade/minute (e.g., 5 to 10 degrees centigrade/minute) and the holding time is generally 3 to 30 hours (e.g., 3 to 10 hours). Since the particle diameter of the powder particles (granulated particles) is small, the desired effect can be achieved at a relatively slow temperature-raising rate (temperature-raising rate of granulation is generally 5 to 20 degrees/minute) and a relatively short heat-retaining time (heat-retaining time is generally 3 to 30 hours).
In an embodiment of the present invention, the method of preparing a composite material according to the present invention may further include a step S500 of sieving the sintered powder particles. In step S500, the powder particles obtained above are sieved, and the composite material having different particle size ranges is sieved as necessary. In the finally produced composite material, in the structure in which the pore material is adhered to the surface of the spray material by the binder, the structure is a plurality of particles, and the particle diameter of the composite material is larger than that of the original powder particles.
The non-stick pan comprises a base body and a non-stick coating sprayed on the base body, wherein the non-stick coating comprises the composite material, and the base body comprises iron and/or stainless steel. The spray process may be cold spray or thermal spray.
The pore material and the spraying material are granulated, namely, the pore material is adhered to the surface of the spraying material through the adhesive to form the pore spraying granulating material, the pore spraying granulating material can form a non-stick coating through cold and hot spraying, the formed non-stick coating keeps a pore structure and a surface rough structure in the original pore material, oil can be well stored in the daily use process, and good non-stick property is finally provided.
The composite material of the present invention has a pore structure due to the inclusion of the pore material, and thus has non-tackiness; in addition, the composite material has good strength and good bonding force with the surface of the pot due to the inclusion of the spray coating material. The non-stick cookware with lasting non-stick effect can be obtained by spraying the composite material on the surface of the cookware.
The method for preparing the composite material of the present invention will be described in detail with reference to examples.

And conveying the slurry to a high-speed liquid throwing disc at 8000 rpm to form liquid drops, blowing the liquid drops into a drying tower at 300 ℃ by hot air at 70 ℃, and forming spherical powder particles after 10 seconds in the descending process of the liquid drops.
