[0001] The present application relates to the technical field of composite materials, and in particular to a lightweight multifunctional maintenance system and its use method and application. Background Art

[0002] Since most military weapons are made of steel products, they are prone to rust. When it snows, the temperature drops sharply, which not only increases the brittleness of steel products and changes the crystal structure inside the metal, making it prone to rust. When the weapons are exposed to humid air, the ice will re-condense inside the weapons when fired, further aggravating the severity of rust. In addition, the corrosiveness of the combustion gases will cause the surface of the components to be rough, and once ice forms, it will adhere strongly and is not easy to fall off, which can easily cause accidents.

[0003] Currently, however, military weapon maintenance still relies on manual cleaning and oiling. This can lead to rust on the trigger, especially after rain, causing the weapon to completely fail. Even with regular use of oil, rust is still unavoidable. In cold or even extremely cold regions, the oil's viscosity increases and can even solidify, rendering a significant portion of weapons useless and severely impacting the development of my country's military capabilities. This also results in a significant waste of military personnel. Furthermore, inadequate weapon maintenance can cause injury to personnel when using firearms and other weapons.

[0028] In order to further understand the present application, the present application is further described in detail below in conjunction with the best embodiment.

[0029] Example 1

[0030] This embodiment provides a lightweight multifunctional maintenance system, including a chemical storage area, a mixing and stirring device, a coating device and a metal product placement device; the chemical storage area is located above the mixing and stirring device and is airtightly connected to the mixing and stirring device; the mixing and stirring device is connected to the coating device and is used to apply chemicals to the metal products placed in the metal product placement device.

[0032] The chemical storage area includes at least three chemical placement spaces, namely the first chemical placement space, the second chemical placement space and the third chemical placement space; as shown in Figure 2, a mixing and stirring device is provided at the bottom of each chemical placement space; an opening is provided at the bottom of the chemical placement space; the opening is directly connected to the mixing and stirring device or connected through a pipeline.

[0033] The opening is an openable opening; that is, when chemicals are not required to enter the mixing and stirring device, the chemical placement space is a closed space; when chemicals are required to enter the mixing and stirring device, the opening can be used to allow the chemicals to enter the mixing and stirring device.

[0034] The three chemical placement spaces are respectively space I for placement of organosilicon precursor monomers, space II for placement of network or gel structure precursors containing hydrophilic groups, and space III for placement of aliphatic compound precursors.

[0035] The placement space I includes at least one placement bin; the placement bin is a precursor monomer of the organosilicon; the precursor monomer of the organosilicon includes a halogen-substituted silane, and the halogen is preferably chlorine, that is, the precursor monomer of the organosilicon preferably includes a chlorosilane; the precursor monomer can be a halogen-substituted silane with a saturated group, for example, it can be dimethyldichlorosilane, methyltrichlorosilane, diethyldichlorosilane, methylethyldichlorosilane, dipropyldichlorosilane, ethylpropyldichlorosilane, methylpropyldichlorosilane, dibutyldichlorosilane, ethyltrichlorosilane, propyltrichlorosilane, butyltrichlorosilane, etc.; the precursor monomer can be an unsaturated halogen-substituted silane, for example, it can be methyl-propylene-dichlorosilane, methyltrichlorosilane, etc.

[0036] Placement space II contains at least two independent placement chambers. One placement chamber contains: a precursor having a hydrophilic group-containing reticular or gel structure, including an enol, an ene acid, or an ene amide with or without substitution; for example, it can be propylene alcohol, acrylic acid, or acrylamide with or without substitution. The other placement chamber contains an initiator, which includes an inorganic initiator and / or an organic initiator. Inorganic initiators include potassium persulfate, ammonium persulfate, sodium perbromide, or hydrogen peroxide. Organic initiators include benzoyl peroxide, lauroyl peroxide, tert-butylhydroxyperoxide, azobisisobutyronitrile, azobisdimethylvaleronitrile, sodium azobiscyanovalerate, and the like.

[0037] The placement space III includes at least four independent placement compartments.

[0038] One storage chamber contains a precursor of an aliphatic compound. The precursor of the aliphatic compound is an alkyl, alkenyl, or alkynyl group containing a substituent and / or a polymer formed by an alkenyl or alkynyl group containing a substituent. When the precursor of the aliphatic compound is an alkyl, alkenyl, or alkynyl group containing or not containing a substituent, it is preferably a halogen-substituted alkyl, alkenyl, or alkynyl group, and may be a C5-C20 halogenated alkyl, alkenyl, or alkynyl group, such as perfluorobutylene or cyclopentene. When the aliphatic compound is a polymer, the precursor of the aliphatic compound is a polyolefin or polyalkyne containing a substituent, and may be polyvinyl chloride, polypropylene chloride, polydichloroprene, polychloroprene, polychloropentene, etc.

[0039] A catalyst is placed in a storage bin; the catalyst includes organic catalysts and / or inorganic catalysts; organic catalysts include tin salts, metal halogen salts, sulfates, etc.; inorganic catalysts include potassium hydroxide, sodium carbonate or sodium bicarbonate, etc.

[0040] A dispersant is placed in a storage bin; the dispersant includes one of gelatin, polyvinyl alcohol, carboxymethyl cellulose or hydroxypropyl cellulose.

[0041] One of the storage bins contains an initiator, which includes one or more mixtures of diisopropyl peroxydicarbonate, azobisisoheptonitrile, lauroyl peroxide, acetyl peroxycyclohexanesulfonic acid or dicyclohexyl peroxydicarbonate.

[0042] Each chemical storage compartment is a vacuum-sealed space; that is, each chemical storage compartment is in an independent vacuum state, which is convenient for chemical storage. Each storage compartment is also an independent space state and is not shared with other storage compartments.

[0043] The mixing and stirring device is provided with an agitator located at the bottom of the mixing and stirring device. The mixing and stirring device also has a feed port through which water or an organic solvent can be injected. The liquid to be injected can be selected according to the properties of each chemical.

[0044] A channel is provided on the side wall of the mixing and stirring device; the channel is connected to the coating device pipeline.

[0045] The coating device comprises: a pipeline connected with the channel, a valve and a spraying panel.

[0046] The solution in the mixing and stirring device can enter the coating device through a pipeline; the amount of the solution and the control time are controlled by a valve.

[0047] The coating device may further include a motor to generate suction so that the solution enters the pipeline or flows according to the direction of the pipeline.

[0048] The size of the spraying panel is not less than the size of the metal product placement device, which can ensure that the surface of the metal product can be sprayed; and can avoid uneven coating caused by back and forth spraying, thereby achieving uniform coating.

[0049] The system also includes a cooling device and a vent; the cooling device cools the mixing and stirring device and the chemical placement space; in the mixing and stirring device, in order to avoid rapid reaction between chemicals, the cooling device is used to cool the reaction system, reduce the reaction rate, and slow down the reaction process.

[0050] The cooling device includes a cold water circulation device; the cold water circulation device surrounds the outside of the mixing and stirring device. That is, the temperature of the reaction system is controlled by circulating cold water.

[0051] Chemical storage spaces require cooling because some chemicals must remain in good condition at low temperatures to avoid deterioration and shortened lifespans caused by high temperatures. The cooling device is located inside the chemical storage space / outside the storage bin, meaning it doesn't come into direct contact with the chemicals and is also located outside the chemical container. The cooling device contains liquid nitrogen. When the liquid nitrogen vaporizes, it removes a significant amount of heat, thereby maintaining a low temperature within the chemical storage space.

[0052] The vents are located around the metal product storage device to enable timely exhaust.

[0053] The metal product storage device is preferably located above the chemical storage area and has an air inlet connected to the chemical storage area. Through the air inlet, vaporized liquid nitrogen can rise into the metal product storage device, thereby maintaining a nitrogen atmosphere when coating the metal product surface.

[0054] A heating device is also provided around the metal product placement device; preferably, the heating device is a heating pipe; the heating pipe is a hollow structure containing a flowing medium inside; preferably, hot water; more preferably, water circulated in a cold water circulation device or water circulated in a cold water circulation device that has been heated.

[0055] Example 2

[0056] This embodiment provides a method for using a lightweight multifunctional maintenance system. The lightweight multifunctional maintenance system is the same as that described in Example 1 and will not be described in detail here.

[0057] The lightweight multifunctional maintenance system as described above includes: (1) opening a chemical placement space to allow chemicals to enter a mixing and stirring device for mixing and stirring; and (2) allowing the mixed and stirred solution to enter a coating device for coating the metal product.

[0058] Place chemicals in the chemical placement space, and place different chemicals in different placement spaces; place substances that can interact with each other in the same placement space.

[0059] For example, the precursor monomer of the silicone is placed alone in the placement space I; the precursor of the network or gel structure containing a hydrophilic group and the initiator that can trigger the reaction of the substance are placed in different placement chambers of the placement space II; the precursor of the aliphatic compound, the catalyst that catalyzes the precursor, the dispersant for dispersion and the initiator that triggers the reaction are placed in different placement chambers of the placement space III.

[0060] The air is then extracted to make each storage chamber vacuum-sealed. A cooling device is then placed to keep the chemical storage space at a certain temperature.

[0061] The chemical storage space can be used to store chemicals when the system is not in use.

[0062] When the system needs to be used, it is only necessary to open the opening at the bottom of the chemical storage space to allow the chemicals to enter the mixing and stirring device, and the chemicals in the stored state can be used.

[0063] Water or organic solution is injected through the feed port of the mixing and stirring device to dissolve the chemicals into a solution, which is convenient for subsequent spraying.

[0064] At the same time, start the agitator of the mixing and stirring device to fully mix the chemicals.

[0065] The order, time and amount of chemicals entering the mixing and stirring device can be controlled by opening or closing the bottom opening of the chemical storage bin.

[0066] For example, if Space I contains only a single chemical, a silicone precursor monomer, then the bottom opening can be opened directly. Space II contains two chemicals: a hydrophilic precursor with a reticular or gel structure and an initiator capable of initiating a reaction. The hydrophilic precursor with a reticular or gel structure must be mixed with a solvent before the initiator is added to prevent premature reaction. Space III contains an aliphatic compound precursor, a dispersant, and a solvent before the catalyst or initiator is added.

[0067] When the mixing and stirring device is turned on, the cooling device should be turned on to control the temperature of the entire mixing and stirring process and slow down the occurrence of the cross-linking reaction at this stage.

[0068] The mixed solution is then transported to the spray panel through a pipe to spray the metal products.

[0069] When three layers of different chemicals are to be sprayed on a metal product, the chemical placement space and the opening at the bottom of the placement bin in each placement space need to be controlled simultaneously to achieve the entire three-layer structure.

[0070] First, open the bottom opening of the storage bin for the organosilicon precursor monomer in the storage space I, and at the same time open the cooling device, stirrer and feed port of the corresponding mixing and stirring device. The solvent of the feed port is water. The molar ratio of the solvent I to the organosilicon precursor monomer is controlled to be not less than 3:1, preferably (3-10):1, which can be 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1 or 10:1. At this ratio, the organosilicon precursor monomer undergoes hydrolysis reaction to the greatest extent without undergoing dehydration or dehydrochlorination reaction, that is, in this step, the amount of polysiloxane generated is relatively small; its purpose is to minimize the early polymerization reaction as much as possible because in situ polymerization will be carried out later. At the same time, the cooling device is turned on to further reduce the progress of the reaction.

[0071] The mixed solution then flows through a pipe into a coating device, where it is sprayed onto the metal surface and then air-dried to slightly solidify the layer.

[0072] When solution I is applied to the metal surface, it is partially dried so that the layer generates a low polymer of polysiloxane, which can partially adhere to the metal surface; then solution II is applied on top of the first layer and also partially dried so that the organic complex layer and the hydrophilic layer are partially cross-linked.

[0073] While the first layer air-dries, the bottom opening of the storage compartment for the hydrophilic-group-containing mesh or gel precursor in Space II is opened. Simultaneously, the cooling device, agitator, and feed port of the corresponding mixing and stirring device are installed. The solvent in the feed port is water. Next, the bottom opening of the initiator storage compartment is opened, and the solution is rapidly piped into the coating device for spray coating on the metal surface. Air-drying is then performed to slightly solidify the layer.

[0074] While the second layer is air-drying, the bottom opening of the storage compartment for the aliphatic compound precursor and dispersant in Space III is opened. Simultaneously, the cooling device, agitator, and feed port of the corresponding mixing and stirring device are connected. The solvent in the feed port is water or an organic solvent. Next, the bottom opening of the storage compartment for the catalyst and / or initiator is opened, and the solution is rapidly piped into the coating device for spray coating on the metal surface.

[0075] Due to the vaporization of liquid nitrogen, the space where the metal product storage device is located is filled with nitrogen atmosphere, so it only needs to be heated and solidified.

[0076] Turn on the heating device around the metal product storage device; control the temperature to 50-80℃ and the time to 20-60 minutes.

[0077] During heating, the exothermic polymerization reaction of the hydrophilic layer further dehydrates or dehydrochlorinates the organic complex layer, leading to the formation of large quantities of polysiloxane and an increase in its molecular weight. Simultaneously, the polysiloxane crosslinks with the hydroxyl, carboxyl, or amide groups of the hydrophilic layer, enhancing the connection between the two layers. Furthermore, the moisture released by the organic complex layer partially hydrates the hydrophilic layer, slightly decreasing its degree of polymerization and forming a gel or network structure with a certain degree of elasticity. Due to the heat released by the hydrophilic layer, the temperature of the hydrophobic layer also rises significantly, causing it to undergo condensation or crosslinking reactions with the hydrophilic layer, ultimately forming a multifunctional surface care material with a three-layer structure.

[0078] Through the complexation of the organic complex layer with the metal product, it can be closely bonded to the surface of the metal product and repair the defects on the metal surface; the hydrophilic layer can store a certain amount of water and reduce the impact of water on the metal, while the hydrophobic layer can prevent the intrusion of water vapor.

[0079] Example 3

[0080] The lightweight multifunctional maintenance system and maintenance method in the above-mentioned embodiment can also be modified to make them more suitable for portable and rapid maintenance.

[0081] When only small arms or parts are to be maintained, the above maintenance system will cause certain waste, so the above maintenance system is modified to be a portable and small maintenance method.

[0082] The chemical storage area and mixing and stirring device are the same as those described above, except that an opening is provided in the mixing and stirring device. The opening is connected to the non-woven fabric device through a pipe and is used to soak the non-woven fabric in chemicals.

[0083] The nonwoven fabric device includes a robotic arm and a nonwoven fabric storage space. Within the nonwoven fabric storage space is a nonwoven fabric rack. A nonwoven fabric is placed on the rack, and a mixing and stirring device is opened to allow the mixed chemical solution to soak the nonwoven fabric. Once a portion of nonwoven fabric is soaked, the robotic arm removes it and replaces it with a new nonwoven fabric on the rack.

[0084] The soaked non-woven fabric is then vacuum-packed to obtain a portable maintenance cloth.

[0085] The production and storage process of the portable maintenance cloth are both in a low-temperature state; for example, it can be refrigerated in liquid nitrogen, liquid CO2 or ice cubes.

[0086] When the weapon part needs to be maintained, the portable maintenance cloth prepared above can be used for maintenance.

[0087] The chemicals in different chemical placement spaces are mixed separately, and the openings of the mixing and stirring devices are opened respectively, so that the mixed chemical solutions can infiltrate the non-woven fabrics; and vacuum packaging is performed to obtain three different portable maintenance cloths.

[0088] After unpacking the portable maintenance cloth containing Solution I, wipe and squeeze the metal surface to allow Solution I to fall onto the metal surface; then air-dry for 5 minutes.

[0089] After that, unpack the portable maintenance cloth containing Solution II, wipe and squeeze it to allow the substance containing Solution II to fall onto the metal surface; then air-dry for 5 minutes.

[0090] Then, unpack the portable maintenance cloth containing Solution III, wipe and squeeze it, so that the substance containing Solution III falls onto the metal surface.

[0091] Then the temperature is raised and controlled to be 50-80°C for 20-60 minutes; thus, the metal surface can be maintained and a three-layer structure can be achieved on the surface.

[0092] The details are as follows:

[0093] Chemical storage space: Storage space I has one storage bin, which is a plastic barrel; Storage space II has two storage bins, both of which are plastic barrels; Storage space III has four storage bins, one of which is a steel cylinder and three are plastic barrels.

[0094] Place dimethyldichlorosilane in storage space I; place acrylamide and ammonium persulfate in the two storage bins of storage space II; place vinyl chloride in the steel cylinder storage bin of storage space III, and place polyvinyl alcohol, diisopropyl peroxydicarbonate, and potassium hydroxide in the plastic barrel storage bin of storage space III. Then, extract the air so that each storage bin is in a vacuum-sealed state. The above chemicals are kept at a low temperature by slowly releasing liquid nitrogen from the cooling device. The metal product storage device is located above the chemical storage area and has an air inlet connected to the chemical storage area; at the same time, open the air inlet so that the metal product storage device is in a nitrogen atmosphere.

[0095] Turn on the cooling device of the mixing and stirring device, which is a cold water pipe surrounding the periphery of the mixing and stirring device, to cool down the device with cold water in advance.

[0096] First, the bottom opening of the dimethyldichlorosilane storage bin in the storage space I was opened, which was directly connected to the mixing and stirring device. That is, when the opening was opened, dimethyldichlorosilane fell into the mixing and stirring device; after the number of parts of dimethyldichlorosilane reached 150 parts, the opening was closed; the feed port of the mixing and stirring device was opened, and 450 parts of water was injected; the agitator was turned on for stirring to obtain solution I.

[0097] The mixed and stirred solution I enters the non-woven fabric storage space through the opening on the side wall of the mixing and stirring device, and soaks the non-woven fabric on the non-woven fabric rack; after soaking, the soaked non-woven fabric is removed by a robotic arm and then vacuum-packed to obtain a portable maintenance cloth containing solution I.

[0098] Open the bottom opening of the acrylamide storage bin in the storage space II, which is directly connected to the mixing and stirring device. After the acrylamide reaches 20 parts, close the opening; open the feed port of the mixing and stirring device, and inject 180 parts of water; turn on the agitator to stir and mix evenly; then open the bottom opening of the ammonium persulfate storage bin in the storage space II, add 1 part, mix and stir to obtain solution II.

[0099] Then, solution II is quickly introduced into the non-woven fabric storage space through the opening on the side wall of the mixing and stirring device to soak the non-woven fabric on the non-woven fabric rack; after soaking, the soaked non-woven fabric is removed by a robotic arm and then vacuum-packed to obtain a portable maintenance cloth containing solution II.

[0100] At the same time, open the bottom openings of the vinyl chloride storage bin and the polyvinyl alcohol storage bin in the storage space III, add 100 parts of vinyl chloride and 0.8 parts of polyvinyl alcohol, and then close the openings; open the feed port of the mixing and stirring device, and inject 120 parts of water; turn on the agitator to stir and mix evenly; then open the openings at the bottom of the diisopropyl peroxydicarbonate storage bin and the potassium hydroxide storage bin in the storage space II, add 0.1 parts of diisopropyl peroxydicarbonate and 0.1 parts of potassium hydroxide, mix and stir to obtain solution III.

[0101] Then, solution III is quickly introduced into the non-woven fabric storage space through the opening on the side wall of the mixing and stirring device to soak the non-woven fabric on the non-woven fabric rack; after soaking, the soaked non-woven fabric is removed by a robotic arm and then vacuum-packed to obtain a portable maintenance cloth containing solution III.

[0102] After unpacking the portable maintenance cloth containing Solution I, wipe and squeeze the metal surface to allow Solution I to fall onto the metal surface; then air-dry for 5 minutes.

[0103] After that, unpack the portable maintenance cloth containing Solution II, wipe and squeeze it to allow the substance containing Solution II to fall onto the metal surface; then air-dry for 5 minutes.

[0104] Then, unpack the portable maintenance cloth containing Solution III, wipe and squeeze it, so that the substance containing Solution III falls onto the metal surface.

[0105] The temperature around the metal is controlled at 60°C and the heating time is 60 minutes. After that, until the temperature of the metal surface drops to room temperature, a maintenance structure with a three-layer structure (organic complex layer, hydrophilic layer and hydrophobic layer) on the surface of the metal product can be obtained, thereby achieving maintenance of the metal product.

[0106] Example 4

[0107] According to the content of this application, the lightweight multifunctional maintenance system of Example 1 and the method of use of Example 2 are specifically described as follows:

[0108] Test Example 1

[0109] Chemical storage space: Storage space I has one storage bin, which is a plastic barrel; Storage space II has two storage bins, both of which are plastic barrels; Storage space III has four storage bins, one of which is a steel cylinder and three are plastic barrels.

[0110] Place dimethyldichlorosilane in storage space I; place acrylamide and ammonium persulfate in the two storage bins of storage space II; place vinyl chloride in the steel cylinder storage bin of storage space III, and place polyvinyl alcohol, diisopropyl peroxydicarbonate, and potassium hydroxide in the plastic barrel storage bin of storage space III. Then, extract the air so that each storage bin is in a vacuum-sealed state. The above chemicals are kept at a low temperature by slowly releasing liquid nitrogen from the cooling device. The metal product storage device is located above the chemical storage area and has an air inlet connected to the chemical storage area; at the same time, open the air inlet so that the metal product storage device is in a nitrogen atmosphere.

[0111] Turn on the cooling device of the mixing and stirring device, which is a cold water pipe surrounding the periphery of the mixing and stirring device, to cool down the device with cold water in advance.

[0112] First, the bottom opening of the dimethyldichlorosilane storage bin in the storage space I was opened, which was directly connected to the mixing and stirring device. That is, when the opening was opened, dimethyldichlorosilane fell into the mixing and stirring device; after the number of parts of dimethyldichlorosilane reached 150 parts, the opening was closed; the feed port of the mixing and stirring device was opened, and 450 parts of water was injected; the agitator was turned on for stirring to obtain solution I.

[0113] The mixed and stirred solution I enters the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, the solution I is evenly passed through and finally reaches the spraying panel to achieve the first layer of spraying. After the first layer is sprayed, it is air-dried.

[0114] While the first layer is air-dried, the bottom opening of the acrylamide storage bin in the storage space II is opened, and the opening is directly connected to the mixing and stirring device. After the acrylamide reaches 20 parts, the opening is closed; the feed port of the mixing and stirring device is opened, and 180 parts of water are added; the stirrer is turned on to stir and mix evenly; then the bottom opening of the ammonium persulfate storage bin in the storage space II is opened, and 1 part is added, and mixing and stirring are performed to obtain solution II.

[0115] Then, solution II is quickly introduced into the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, solution II is uniformly passed through and finally reaches the spraying panel to achieve the second layer of spraying. After the second layer of spraying, it is air-dried.

[0116] While the second layer is air-drying, the bottom openings of the vinyl chloride storage bin and the polyvinyl alcohol storage bin in the storage space III are opened simultaneously, and 100 parts of vinyl chloride and 0.8 parts of polyvinyl alcohol are added, and then the openings are closed; the feed port of the mixing and stirring device is opened, and 120 parts of water are injected; the stirrer is turned on for stirring and mixing evenly; then the openings at the bottom of the diisopropyl peroxydicarbonate storage bin and the potassium hydroxide storage bin in the storage space II are opened, 0.1 parts of diisopropyl peroxydicarbonate and 0.1 parts of potassium hydroxide are added, and mixed and stirred to obtain solution III.

[0117] Then, solution III is quickly passed into the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, solution III passes evenly and finally reaches the spraying panel to achieve the third layer of spraying.

[0118] The metal product storage device then passes through a heating device surrounding the device. This heating device is a hot water pipe surrounding the mixing device. The hot water is heated from the cold water pipe. The temperature around the metal product storage device is controlled at 60°C for 60 minutes. After the temperature of the metal surface cools to room temperature, a three-layered surface maintenance structure (organic complex layer, hydrophilic layer, and hydrophobic layer) is formed, achieving the desired maintenance of the metal product.

[0119] Test Example 2

[0120] Chemical storage space: Storage space I has one storage bin, which is a plastic barrel; Storage space II has two storage bins, both of which are plastic barrels; Storage space III has four storage bins, all of which are plastic barrels.

[0121] Vinyltrichlorosilane is placed in storage space I; acrylic acid and ammonium persulfate are placed in the two storage bins of storage space II; polyvinyl chloride, polyvinyl alcohol, ammonium persulfate and triazole dimercaptoamine salt are placed in the plastic barrel storage bin of storage space III.

[0122] The air is then extracted, leaving each storage compartment in a vacuum-tight state. The chemicals are kept cold by slowly releasing liquid nitrogen from the cooling device. The metal product storage device is located above the chemical storage area and has an air inlet connected to the chemical storage area. This air inlet is simultaneously opened, exposing the metal product storage device to a nitrogen atmosphere.

[0123] Turn on the cooling device of the mixing and stirring device, which is a cold water pipe surrounding the periphery of the mixing and stirring device, to cool down the device with cold water in advance.

[0124] First, the bottom opening of the vinyltrichlorosilane storage bin in the storage space I was opened. The opening was directly connected to the mixing and stirring device. That is, when the opening was opened, the vinyltrichlorosilane fell into the mixing and stirring device. After the number of parts of vinyltrichlorosilane reached 150 parts, the opening was closed. The feed port of the mixing and stirring device was opened and 450 parts of water was injected. The stirrer was turned on for stirring to obtain a solution I.

[0125] The mixed and stirred solution I enters the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, the solution I is evenly passed through and finally reaches the spraying panel to achieve the first layer of spraying. After the first layer is sprayed, it is air-dried.

[0126] While the first layer is air-drying, the bottom opening of the acrylic acid storage bin in storage space II is opened, and the opening is directly connected to the mixing and stirring device. After the number of parts of acrylic acid reaches 20, the opening is closed; the feed port of the mixing and stirring device is opened, and 180 parts of water are added; the stirrer is turned on to stir and mix evenly; then the bottom opening of the ammonium persulfate storage bin in storage space II is opened, and 1 part is mixed and stirred to obtain solution II.

[0127] Then, solution II is quickly introduced into the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, solution II is uniformly passed through and finally reaches the spraying panel to achieve the second layer of spraying. After the second layer of spraying, it is air-dried.

[0128] While the second layer is air-drying, the bottom openings of the polyvinyl chloride storage bin and the polyvinyl alcohol storage bin in the storage space III are opened simultaneously, and 100 parts of polyvinyl chloride and 0.8 parts of polyvinyl alcohol are added, and then the openings are closed; the feed port of the mixing and stirring device is opened, and 120 parts of water are injected; the stirrer is turned on for stirring and mixing evenly; then the openings at the bottom of the ammonium persulfate storage bin and the triazole dimercaptoamine salt storage bin in the storage space II are opened, 0.1 parts of ammonium persulfate and 1 part of triazole dimercaptoamine salt are added, and the mixture is mixed and stirred to obtain solution III.

[0129] Then, solution III is quickly passed into the coating device through the channel on the side wall of the mixing and stirring device. By controlling the valve, solution III passes evenly and finally reaches the spraying panel to achieve the third layer of spraying.

[0130] The metal product storage device then passes through a heating device surrounding the device. This heating device is a hot water pipe surrounding the mixing device. The hot water is heated from the cold water pipe. The temperature around the metal product storage device is controlled at 60°C for 60 minutes. After the temperature of the metal surface cools to room temperature, a three-layered surface maintenance structure (organic complex layer, hydrophilic layer, and hydrophobic layer) is formed, achieving the desired maintenance of the metal product.

[0131] By conducting a neutral salt spray test on the metal products after the above maintenance, no rust was found after 4000 hours; this shows that the metal surface has a complete organic complex layer, hydrophilic layer and hydrophobic layer, and the layers are cross-linked and bonded to each other to form a stable network structure. The hydrophobic layer can reject most moisture intrusion, and the hydrophilic layer can firmly lock the moisture inside the metal and the moisture that seeps in, preventing it from extending to the metal layer; the organic complex layer complexes with the free iron in the metal, further preventing the free iron from oxidizing and rusting.

[0132] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
