Description

[0002] The existing small-particle one-piece molding products have many processes and a long production cycle. In addition, the products have to go through three processes of copper plating, nickel plating, and tin plating after laser processing, and are immersed in acid and alkali baths for a long time, causing the product powder to corrode and rust. In addition, the manufacturer also has inconsistent phosphating layer thickness during the phosphating process of the powder. The above factors cause the small one-piece finished products to rust after electroplating, and the body is also prone to rust during later storage.

[0003] Some manufacturers in this product industry currently use silver printing and water plating and vacuum plating to make electrodes, which has the disadvantages of high cost and complicated processes. Another method of further rust-proofing the finished products after electroplating increases labor intensity, increases cost, and also causes the disadvantage of mixing materials.

[0036] First determination step: Get the mass M of the insulating material total , set the virtual proportion value to 3‰, and calculate the mass M of the rust removal material rust , expressed by the calculation formula: M rust =M total *3‰;

[0037] Second determination step: Set the virtual proportion values ​​to 3.5‰ and 2.5‰, and calculate the judgment mass M of the rust removal material rust ′ and M rust ″, expressed by the calculation formula:

[0039] Three determination steps: When the result is not a special calculation, the two sets of virtual proportion values ​​are averaged to obtain the calculated value α, and the new judgment mass M of the rust removal material is calculated. new , expressed by the calculation formula: M new =M total *α;

[0040] Then use the salt spray test to judge the quality of the rust removal material new 、M rust ′ and M rust “To make comparisons;

[0041] When the quality of the rust removal material is judged to be M new Best, and the judgment quality of the rust removal material M rust 'Secondly, set the virtual proportion value to 3.75‰;

[0048] In a third aspect, an embodiment of the present invention provides a computer device, including a memory and a processor, wherein the memory stores a computer program, wherein: when the processor executes the computer program, any step of the above-mentioned one-piece molded powder rust prevention preparation method is implemented.

[0050] The beneficial effects of the present invention are:

[0051] By soaking the raw powder in a mixture of phosphoric acid and acetone and then removing the acetone, a thin and uniform insulating layer can be effectively formed on the surface of the metal powder, which not only enhances the electrical insulation performance of the final product, but also significantly improves its electrical insulation ability. This dual effect is particularly valuable for electronic components that require both good conductivity and excellent corrosion resistance. In addition, the baking process at 70°C can completely evaporate the residual solvent, ensuring that the finished product is dry and moisture-free. At the same time, at this temperature, it can also ensure that the material will not be damaged.

[0052] The addition of ethylene glycol methyl ether-2-propanol and oleyl glycerol not only promotes the uniform dispersion of other active ingredients in the entire system, but more importantly, they greatly improve the lubricity and fluidity between powders, which makes the subsequent screening, baking, cooling and even the final glue granulation process smoother and more efficient, reducing operational difficulties caused by material adhesion. In addition, good fluidity also helps to improve production efficiency on automated production lines and reduce scrap rates.

[0053] The combination of zinc chloride and salicylic acid can quickly generate a dense and non-removable protective film on the metal surface. This protective film is not just a physical barrier, but also has a certain chemical reaction activity. It can interact with the metal surface, thereby changing the energy state of the metal surface and further enhancing the anti-corrosion effect. This surface modification will have a positive effect on certain types of coatings or subsequent processes, such as improving paint film adhesion or improving welding quality.

[0054] The proportional addition of rust-removing materials can further enhance the anti-rust effect of the finished powder product, avoiding the situation where less rust-removing materials cannot achieve the expected effect. At the same time, it can also avoid the situation where more rust-removing materials will have an adverse effect on other properties of the finished powder product. For example, in some application scenarios, such as electronic component packaging materials or conductive coatings, the powder needs to maintain specific electrical properties, and any significant changes may cause the product to fail to meet the design requirements.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] Example 1

[0064] Reference Figure 1, which is the first embodiment of the present invention, provides a method for preparing an integrally formed powder rust-proof material, comprising:

[0065] Insulating the raw powder to obtain insulating material;

[0066] In this field, the raw powder is generally metal powder: such as silver powder, copper powder, aluminum powder, etc., which are often used to make conductive paste, thick film resistors, solder paste and electromagnetic shielding materials;

[0067] When the raw powder is insulated, the following steps are included:

[0068] Put phosphoric acid and acetone into a container and stir, then add the original powder and soak for 2 hours;

[0069] Then the raw powder is blown by a fan and stirred at the same time to volatilize the acetone;

[0070] The volatilized raw powder is placed in an oven for baking, the temperature is set to 70°C, the baking time is set to 40 to 60 minutes, and finally cooled until the temperature is less than 20°C to obtain an insulating material;

[0071] Among them, the mass ratio of phosphoric acid, acetone and raw powder is 1:120:1000.

[0072] By soaking the raw powder in a mixture of phosphoric acid and acetone and then removing the acetone, a thin and uniform insulating layer can be effectively formed on the surface of the metal powder, which not only enhances the electrical insulation performance of the final product, but also significantly improves its electrical insulation ability. This dual effect is particularly valuable for electronic components that require both good conductivity and excellent corrosion resistance. In addition, the baking process at 70°C can completely evaporate the residual solvent, ensuring that the finished product is dry and moisture-free. At the same time, at this temperature, it can also ensure that the material will not be damaged.

[0073] Mixing the insulating material with the rust removing material to obtain a mixture;

[0074] The rust removal materials are calculated by mass:

[0075] Ethylene glycol methyl ether-2-propanol: 0.5 parts;

[0076] Olein: 2 parts;

[0077] The addition of ethylene glycol methyl ether-2-propanol and oleyl glycerol not only promotes the uniform dispersion of other active ingredients in the entire system, but more importantly, they greatly improve the lubricity and fluidity between powders, which makes the subsequent screening, baking, cooling and even the final glue granulation process smoother and more efficient, reducing operational difficulties caused by material adhesion. In addition, good fluidity also helps to improve production efficiency on automated production lines and reduce scrap rates.

[0078] Protective agent: 13.5 parts;

[0079] Lubricant: 15 parts;

[0080] Acetate: 1 part;

[0081] Although acetate (1 part) is used mainly to adjust the pH value in this formula, in fact, the right amount of acetate can also play a certain antibacterial and antimicrobial role. This means that the material can not only prevent metal from rusting, but also inhibit the growth of microorganisms, which is an additional benefit for parts used in food processing machinery, medical devices and other fields. This added value opens up new possibilities for the application range of the material, especially in industries with high hygiene requirements.

[0082] Wherein, the protective agent is calculated by mass:

[0083] Zinc chloride: 1.5 parts;

[0084] Salicylic acid: 12 parts;

[0085] The combination of zinc chloride and salicylic acid can quickly generate a dense and non-removable protective film on the metal surface. This protective film is not just a physical barrier, but also has a certain chemical reaction activity. It can interact with the metal surface, thereby changing the energy state of the metal surface and further enhancing the anti-corrosion effect. This surface modification will have a positive effect on certain types of coatings or subsequent processes, such as improving paint film adhesion or improving welding quality.

[0086] The lubricant is calculated by mass:

[0087] Sodium dioctyl sulfosuccinate: 13 parts;

[0088] Butylated hydroxyanisole: 2 parts.

[0089] The lubricant uses sodium dioctyl sulfosuccinate as one of the main ingredients. In addition to providing excellent lubrication performance, this substance also exhibits a certain self-repairing ability. When the material is slightly damaged, these lubricant molecules can rearrange and fill the gaps in the damaged area to restore the original smoothness and flatness. This feature is very helpful in extending the service life of the product, especially for parts used under dynamic friction conditions.

[0090] The mixture is sieved, baked and cooled to obtain the finished product;

[0091] The mixture is screened by a vibrating screening machine with a 60-mesh screen. The drying furnace is preheated to the set working temperature (70°C), the screened mixture is placed in the drying furnace, the residence time is set (40 to 60 minutes), and the temperature change and humidity level are monitored in real time through the monitoring system. After drying, the material is moved out of the drying furnace with the conveyor belt, transferred to a sealed container for storage, and then placed in a refrigeration room for cooling.

[0092] The finished product is subjected to a glue-adding and granulation process to obtain a powdery finished product;

[0093] Turn on the power of the extruder, preheat the barrel and die head in advance to reach the predetermined operating temperature range. When the temperature stabilizes, start adding the screened and dried finished product into the hopper. The screw speed is 50-70rpm and the screw aspect ratio is between 20:1 and 30:1 to facilitate full plasticization and exhaust of the finished product.

[0094] Example 2

[0095] On the basis of the first embodiment, this embodiment further provides a method for preparing a rust removal material, comprising:

[0096] At a temperature of 45°C to 55°C, add oleylglycerol and ethylene glycol methyl ether-2-propanol into the reaction bottle, and shake the reaction bottle for 10 to 15 minutes;

[0097] Add 5-10 parts of protective agent and 6-11 parts of lubricant within 25 minutes, stir for 30 minutes, and obtain product A;

[0098] Add acetate and the remaining protective agent and lubricant to another set of reaction bottles, shake the reaction bottles for 10 to 15 minutes, and obtain product B;

[0099] Mix product A and product B together, blow the original powder through a fan and stir at the same time to obtain the rust removal material.

[0100] By adding the protective agent and lubricant to different reaction systems separately, it is possible to avoid unnecessary side reactions that may occur when the two are in direct contact. For example, in some cases, the mixing of protective agents with certain types of lubricants may cause precipitation or form insoluble complexes, which not only wastes active ingredients but may also lead to reduced product performance. By adding them in batches, they can work under their most suitable conditions, thereby improving the chemical stability of the entire formulation.

[0101] Secondly, adding them separately helps improve the uniformity of the distribution of the protective agent and lubricant in the matrix. First, prepare product A containing olein and ethylene glycol methyl ether-2-propanol, then introduce the protective agent and lubricant; in another independent step, process the acetate and other remaining ingredients, and finally mix the two products. This process allows each additive to have enough time and space to fully dissolve or disperse in the medium, reducing the occurrence of agglomeration and ensuring the uniform distribution of each component in the entire system.

[0102] Example 3

[0103] On the basis of the previous two embodiments, this embodiment further provides a mass ratio of rust removal material to powder finished product,

[0104] Specifically, when the insulating material and the rust removal material are mixed, the mass ratio of the rust removal material to the powder product is 2‰ to 4‰.

[0105] Conduct simulation experiments to verify the influence of the mixing ratio of rust removal materials and powder products on the salt spray test results and powder performance

[0106] This experiment aims to verify the specific effects of mixing insulating materials and rust removal materials in different weight ratios on the corrosion resistance (i.e., salt spray effect) and electrical insulation performance (such as dielectric strength or breakdown voltage) of the final powder product in a salt spray environment through a series of controlled variable tests. Special attention is paid to the performance when the ratio of rust removal materials to the total weight of the powder is in the range of 2‰ to 4‰, and the problems that may be caused by exceeding this range are discussed.

[0107] Salt spray test chamber: used to simulate marine climate conditions and evaluate the corrosion resistance of samples.

[0108] Dielectric Strength Tester: Used to measure the electrical insulation properties of a sample, especially the breakdown voltage.

[0109] Group setting: Five different experimental groups were set up, corresponding to the proportion of rust removal materials to the total mass of powder materials of 0.5‰, 2‰, 3‰, 4‰, and 6‰; three parallel samples were prepared for each group to reduce the impact of accidental errors.

[0110] Salt spray test: Place the prepared samples in a neutral salt spray test chamber that complies with GB / T 10125 standard, set the temperature to 35±2℃, the relative humidity ≥95%, and the spray cycle to continuous spray; observe and record the time point when obvious corrosion appears on the surface of the sample, focusing on the changes within 12 hours.

[0111] Electrical insulation performance test: For each group of samples, the breakdown voltage was measured using a dielectric strength tester immediately after the salt spray test to evaluate the effect of the amount of rust removal material added on the electrical insulation performance.

[0112] Table 1: Salt spray test performance of samples at different ratios

[0113]

[0114]

[0115] In the table, “corrosion start time” refers to the time point when obvious signs of corrosion first appear on the sample surface; “white rust area” refers to the proportion of white rust formed on the sample surface after 12 hours of salt spray test; “corrosion depth” reflects the extent to which corrosion products penetrate the material surface.

[0116] Table 2: Dielectric strength (Ui) changes of samples at different ratios

[0117]

[0118] Salt spray effect:

[0119] When the mass proportion of rust removal material was 0.5‰, although all three samples showed different degrees of corrosion, on average, the corrosion started earlier and formed a larger area of ​​white rust and a deeper corrosion layer.

[0120] For samples where the mass ratio of rust removal materials is between 2‰ and 4‰, they can not only effectively prevent the occurrence of corrosion, but even if there is a small amount of corrosion, it is only limited to a very superficial layer, which shows that the formulas under these ratios have good protective effects.

[0121] When the mass proportion of rust removal materials reaches or exceeds 6‰, although the sample still shows strong corrosion resistance, excessive addition may lead to a decline in other performance aspects, such as the electrical insulation performance to be discussed later.

[0122] Electrical insulation performance (Ui):

[0123] Within a relatively low range of rust removal material proportion (such as 0.5‰), the breakdown voltage Ui of the sample is relatively high, but as the proportion gradually increases to about 2‰, the value decreases slightly but still remains within a reasonable level, indicating that an appropriate amount of rust removal material will not significantly affect the electrical properties of the powder.

[0124] However, when the mass proportion of rust removal materials continues to rise to more than 4‰, especially 6‰, we can observe that the breakdown voltage Ui has decreased significantly, while the insulation resistance has increased, and the dielectric loss tangent tanδ has also shown an increasing trend, which may suggest that too many additives have begun to interfere with the internal structure of the powder, thereby affecting its insulation performance.

[0125] In summary, the data from this simulation experiment not only verified the previously proposed hypothesis that when the mass proportion of rust removal materials is controlled within the range of 2‰ to 4‰, the corrosion resistance of the powder product can be effectively improved without negatively affecting its electrical insulation performance; it also revealed some subtle differences, such as individual differences between different samples and the reasons behind them. In addition, these findings once again emphasize the importance of optimizing material formulations to ensure that the final product has both good protective functions and reliable electrical performance.

[0126] Example 4

[0127] On the basis of the first three embodiments, this embodiment further provides a mass ratio of rust removal material to powder finished product.

[0128] The mass proportion of the rust removal material in the finished powder product is determined, which specifically includes the following steps:

[0129] First determination step: Get the mass M of the insulating material total , set the virtual proportion value to 3‰, and calculate the mass M of the rust removal material rust , expressed by the calculation formula: M rust =M total *3‰;

[0130] Second determination step: Set the virtual proportion values ​​to 3.5‰ and 2.5‰, and calculate the judgment mass M of the rust removal material rust ′ and M rust ″, expressed by the calculation formula:

[0131] Then use salt spray test to judge the quality of rust removal materials rust ′ and M rust ″ and the quality of the rust removal material M rust When the comparison result is the judgment quality M of the rust removal material, rust ′When the effect is the best, obtain M rust′ corresponds to the virtual proportion value and M total The corresponding virtual proportion value; when the comparison result is the judgment quality M of the rust removal material rust When the effect is the best, obtain M rust The corresponding virtual proportion value and M total The corresponding virtual proportion value, when the comparison result is the mass M of the rust removal material total When the effect is best, special calculations are performed;

[0132] Three determination steps: When the result is not a special calculation, the two sets of virtual proportion values ​​are averaged to obtain the calculated value α, and the new judgment mass M of the rust removal material is calculated. new , expressed by the calculation formula: M new =M total *α;

[0133] Then use the salt spray test to judge the quality of the rust removal material new 、M rust ′ and M rust “To make comparisons;

[0134] When the quality of the rust removal material is judged to be M new Best, and the judgment quality of the rust removal material M rust 'Secondly, set the virtual proportion value to 3.75‰;

[0135] When the quality of the rust removal material is judged to be M new Best, and the judgment quality of the rust removal material M rust "Secondly, the mass proportion of rust removal materials in the powder product is set to 2.25‰;

[0136] When the quality of the rust removal material is judged to be M new If it is not the best, set the judgment quality M of the rust removal material rust ′ or M rust The corresponding virtual proportion value is the mass proportion of the rust removal material in the powder product.

[0137] The special calculation includes the following steps,

[0138] Set the virtual proportion values ​​to 3.25‰ and 2.75‰, and calculate the judgment mass M of the rust removal material new ′ and M new ″;

[0139] Using salt spray test to judge the quality of rust removal materials rust 、M new ′ and M new ″ and obtain the virtual proportion value corresponding to the judged mass of the rust removal material with the best effect, and use the virtual proportion value as the mass proportion of the rust removal material in the powder product.

[0140] Each time the mass proportion of the rust removal material in the powder product is determined, three sets of determination steps can be performed to further determine the value of the mass proportion. Through such a systematic experimental design, we can effectively determine the optimal mass proportion of the rust removal material in the powder product, thereby ensuring that the corrosion resistance and electrical insulation performance of the product are optimally balanced.
