Description
Technical Field
The invention belongs to the technical field of lubricating fluid for machining, and particularly relates to water-based stamping fluid and a preparation method and application thereof.
Background
Stainless steel is a material resistant to corrosive media such as air, steam, salt water and the like, and has been widely applied to the manufacturing fields of food, catering, medical instruments, household appliances, automobiles, pressure vessels, aerospace and the like since the beginning of the 20 th century. As an important component in a mechanical processing system, the stamping processing of stainless steel is very important for the development of the countryside.
Because stainless steel has the characteristics of high yield strength, large yield ratio, low elongation of materials and the like, the problems of workpiece breakage, scratch, cracking and the like easily occur in the stamping process, and the abrasion to a die can be generated at the same time. To alleviate such a situation, the lubricant used in the stainless steel stamping process needs to have the following characteristics: (1) The extreme pressure property is good, and the good lubricating property can be maintained under the action of high deformation pressure; (2) High temperature resistance, and no decomposition or deterioration in the processing process; (3) the cooling performance is realized, and the mold is prevented from overheating; and (4) corrosion prevention, rust prevention, environmental protection and no harm.
Common types of plastic working lubricants include stamping lubricants, solid stamping lubricants, water-based stamping lubricants, and the like. The water-based stamping lubricant has the advantages of good cooling performance, long service life, good forming effect, safe storage and use, environmental protection, easy treatment of waste liquid, low cost and the like, and is increasingly widely applied. At present, most of lubricating media adopted in stainless steel stamping processing are lubricating oil or solid lubricants, and although the lubricating media can meet the requirements of working conditions, the lubricating media are high in cost, low in service life and poor in cooling performance.
At this stage, there is less disclosure of the use of water-based processing fluids for stainless steel stamping. CN114437862A, CN 109735388B, CN 107384567A, CN 104560353A, CN 104498168A, CN 104212619A, CN 104212621A, CN 102787010B, CN 101255377B, CN 102604731A and CN 101260339B, the described scheme can be applied to punching of soft easily-machined metals such as aluminum foil, copper-zinc alloy and the like, and the defects of the scheme are that the use concentration is high, the extreme pressure performance is poor, and the scheme is difficult to be used for punching high-strength stainless steel. CN108865382A discloses a plant-based water-soluble punching oil, wherein a large proportion of chlorine-based, phosphorus-based, sulfur-based lubricant and antirust agent are added, and the two additives can form competitive adsorption on the surface of metal so as to reduce the action effect; although the abstract can be used by being mixed with water, the use mode described in the specification is to directly use the stock solution, the use cost is high, the wear resistance of the stock solution is low, and the stamping processing requirement of the high-strength stainless steel is difficult to meet.
Therefore, a water-based stamping fluid which has good lubricity and low use concentration and can be used for stamping high-strength stainless steel is required to be developed in the field.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a water-based punching fluid and a preparation method and application thereof. The water-based stamping fluid has good extreme pressure lubrication effect and low use concentration, and can meet the stamping processing requirements of metals, particularly high-strength stainless steel.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the invention provides a water-based punching fluid, which comprises the following components in parts by weight:
14-18 parts of organic base, 10-15 parts of extreme pressure agent and 5-15 parts of oiliness agent, wherein the solvent is water;
the oiliness agent consists of C16-C20 organic acid and C8-C12 organic acid according to the mass ratio of 70-95.
Wherein, the organic alkali can be 14 parts, 14.5 parts, 15 parts, 15.5 parts, 16 parts, 16.5 parts, 17 parts, 17.5 parts or 18 parts by weight.
The weight portion of the extreme pressure agent can be 10 portions, 10.5 portions, 11 portions, 11.5 portions, 12 portions, 12.5 portions, 13 portions, 13.5 portions, 14 portions, 14.5 portions or 15 portions, etc.
The weight portion of the oiliness agent can be 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15.
The mass ratio of the C16-C20 organic acid to the C8-C12 organic acid may be 70.
Organic base
In order to ensure the lubricating performance of the punching liquid, proper amounts of extreme pressure agent and oiliness agent are required to be added. Most of the existing extreme pressure agents and oiliness agents are oil-soluble substances, and the dispersibility in water is poor. The water-based punching fluid adopts the organic alkali, on one hand, the water-based punching fluid can react with the oiliness agent or the oiliness agent and the extreme pressure agent to generate water-soluble substances which are uniformly dispersed in water, so that the lubricating effect of the water-based punching fluid is improved; on the other hand, the pH can be adjusted to enable the pH of the water-based punching liquid to meet the practical use requirement, for example, the pH =8-10 of the optimal corrosion resistant interval of the copper part of the punching die is met.
In some embodiments of the invention, the organic base is an organic amine.
In some embodiments of the invention, the organic base is selected from one or more of monoethanolamine, diethanolamine, triethanolamine, diglycolamine, tricyclohexylamine, dimethylamine, diethylamine, aniline and tetrahydroxymethylamine.
In some embodiments of the invention, the organic base consists of monoethanolamine and triethanolamine.
In some embodiments of the present invention, the organic base consists of monoethanolamine and triethanolamine in a mass ratio of 0.28 to 0.43, for example, 0.28.
The monoethanolamine and triethanolamine have high safety, do not generate respiratory tract irritant substances, and do not cause damage when contacting the skin. Triethanolamine has good stability and a certain anticorrosion effect on metal materials, but when the triethanolamine is used alone, the required addition amount is high in order to meet the alkaline requirement, and the hydrophilicity of the triethanolamine is insufficient due to the large proportion of hydrocarbon content, so that the transparency of the water-based stamping fluid cannot meet the standard; monoethanolamine has high alkalinity, but when the content is too high, the pH of the water-based punching fluid exceeds the optimal corrosion resistance interval (pH = 8-10) of a copper part, and machine parts are damaged. And the monoethanolamine and the triethanolamine are matched according to a proper proportion for use, so that the advantages of the monoethanolamine and the triethanolamine can be combined, and a good synergistic effect is achieved.
Extreme pressure agent
The extreme pressure agent is a heavy load additive which forms an extreme pressure lubricating film with the surface of a friction pair under extreme conditions of high temperature, high pressure and the like. The stainless steel difficult to process needs higher pressure to generate deformation, and a large amount of heat can be generated in the stamping deformation process, so that an extreme pressure agent needs to be added into the stamping fluid to meet the lubricating performance under extreme conditions.
In some embodiments of the invention, the extreme pressure agent is selected from one or more of chlorinated fatty acids, chlorinated paraffins, chlorinated fatty acid esters, phosphate ammonium salts, phosphoramides, sulfurized fats, thioolefins, and benzyl sulfides.
The chlorinated fatty acid has excellent extreme pressure performance, is difficult to corrode stainless steel stamping in actual use, is easy to form a water-soluble substance with organic alkali, and can further improve the lubricating effect of the water-based stamping fluid by matching with an oiliness agent. Therefore, the extreme pressure agent in the present invention is preferably a chlorinated fatty acid. The carbon number of the chlorinated fatty acid is not particularly limited in the present invention, and may be 18, for example.
Oily agent
The oiliness agent can be adsorbed on the friction surface through polar groups to form a molecular oriented adsorption film, so that the metals are prevented from contacting with each other, and friction and abrasion are reduced. Because the extreme pressure agent needs to act under the harsh conditions of high temperature and high pressure and is difficult to play a lubricating effect under the conditions of normal temperature and low load, an oiliness agent needs to be added into the stamping fluid to ensure the lubricating performance of the stainless steel stamping process under the normal temperature and normal pressure state.
According to the invention, organic acids with different carbon chain lengths are compounded at a specific ratio to serve as an oiliness agent, so that the oiliness agent can be completely adsorbed on the surface of a friction pair, a uniform and continuous high-strength lubricating film is formed, and the lubricating effect of the water-based punching fluid is improved. The long carbon chain organic acid has higher strength but relatively larger steric hindrance, and when the content of the long carbon chain organic acid is too high, the continuity of a lubricating film is reduced, and the lubricating effect of the water-based punching liquid is reduced; the medium-short carbon chain organic acid can be adsorbed on the surface of a friction pair to improve the continuity of a lubricating film, but if the content of the organic acid is too high, the strength of the lubricating film is insufficient, and the lubricating effect of the water-based punching fluid is reduced.
In some embodiments of the invention, the mass ratio of the C16-C20 organic acid to the C8-C12 organic acid is 75 to 82.
In some embodiments of the invention, the C16-C20 organic acid is selected from one or more of oleic acid, tall oil, lard oil, whale oil, palm oil fatty acids, preferably tall oil.
In some embodiments of the invention, the C8-C12 organic acid is selected from one or more of neodecanoic acid, n-octanoic acid, isononanoic acid, isooctanoic acid, dodecanoic acid, preferably neodecanoic acid.
Tall oil and neodecanoic acid not only have lower cost, good lubricating property and strong solubilizing property, but also have certain hard water resistance and anti-foaming property. Thus, the oiliness agent in the present invention is preferably composed of tall oil and neodecanoic acid.
Corrosion inhibitor
Since some stainless steel stamping dies contain copper and aluminum, and extreme pressure agents and organic bases in the additives may cause corrosion, it is preferable that the water-based stamping fluid further include a corrosion inhibitor to mitigate the corrosion.
In some embodiments of the invention, the weight portion of the corrosion inhibitor is 0.3 to 0.8 portion; for example, it may be 0.3 parts, 0.4 parts, 0.5 parts, 0.6 parts, 0.7 parts, 0.8 parts, or the like.
In some embodiments of the invention, the corrosion inhibitor is selected from one or more of N, N-dialkylaminomethylenephriazole, benzotriazole, methylbenzotriazole and sodium salt of methylbenzotriazole.
The benzotriazole and the sodium methyl benzotriazole have stronger water solubility and can exist in the stamping fluid more stably, so that the corrosion inhibitor is preferably benzotriazole and/or sodium methyl benzotriazole.
Complexing agents
During the stamping process, some of the metal may precipitate in ionic form. In order to reduce the surface discoloration and the loss of the stamping die caused by the precipitation of metal ions, the water-based stamping fluid preferably further comprises a complexing agent.
In some embodiments of the invention, the complexing agent is present in an amount of 0.1 to 0.2 parts by weight; for example, it may be 0.1 part, 0.11 part, 0.12 part, 0.15 part, 0.16 part, 0.18 part or 0.2 part, etc.
In some embodiments of the invention, the complexing agent is selected from one or more of disodium ethylenediaminetetraacetate, tetrasodium ethylenediaminetetraacetate, sodium tripolyphosphate, sodium pyrophosphate, sodium hexametaphosphate, heptonate, sodium gluconate, sodium alginate, hydroxyethylidene diphosphate, and maleic acrylic acid copolymer.
The disodium ethylene diamine tetraacetate has stronger complexing ability and higher concentration stability, and can stably exist in the stamping fluid. Therefore, the complexing agent in the invention is selected from disodium ethylene diamine tetraacetate.
Defoaming agent
Defoamers are substances that reduce the surface tension of water, solutions, suspensions, etc., prevent the formation of foam, or reduce or eliminate the original foam. In order to prevent the stamping part and the die from being damaged due to bubbles generated by the stamping liquid during use, the water-based stamping liquid preferably further comprises an antifoaming agent.
In some embodiments of the invention, the defoamer is present in an amount of 0.15 to 0.4 parts by weight; for example, it may be 0.15 parts, 0.2 parts, 0.25 parts, 0.3 parts, 0.35 parts, 0.4 parts, or the like.
In some embodiments of the present invention, the defoamer is selected from one or more of glycerol polyoxyethylene ether, polyvinyl alcohol, higher alcohols, silicone defoamer and polyether modified silicone defoamer.
The organic silicon defoamer can be well dispersed in water, has excellent defoaming property, and can meet the performance and use requirements of the punching liquid only by a small amount. Therefore, the defoaming agent in the present invention is preferably a silicone defoaming agent.
In some embodiments of the invention, the water-based punching fluid has a solids content of above 0.725%; for example, it may be 0.725%, 0.75%, 0.78%, 0.8%, 0.82%, 0.85%, 0.88%, 0.9%, 0.92%, 0.95%, 0.98%, 1%, 1.1%, 1.2%, 1.3%, 1.5%, 1.8%, 2%, 2.5%, 3%, 3.5%, 4%, or 4.3%, etc. Preferably 0.9% or more. More preferably 0.9 to 4.3%.
The optimal corrosion-resistant interval of the copper part of the stamping die is pH =8-10, and in order to match the corrosion-resistant interval and reduce the damage of the stamping fluid to the machine part, the pH of the water-based stamping fluid is preferably 8-10; for example, it may be 8, 8.2, 8.5, 8.8, 9, 9.2, 9.5, 9.8, or 10, etc.
In a second aspect, the present invention provides a method for preparing the water-based punching fluid according to the first aspect, the method comprising the steps of:
and mixing the components with water according to a ratio until the mixture is clear and transparent to obtain the water-based punching liquid.
In some embodiments of the invention, the preparation method comprises the following steps:
(1) Mixing organic alkali, extreme pressure agent and oiliness agent, and stirring at 50-55 deg.C until the solution is clear;
(2) Adding water into the mixed solution obtained in the step (1), and stirring until the solution is clear;

It should be noted that the term "optionally added corrosion inhibitor, complexing agent, defoaming agent" as used herein means that the corrosion inhibitor, complexing agent, defoaming agent may be added or not added, depending on whether the component is contained in the aqueous punching fluid of the first aspect or not.
In the invention, when the water-based stamping fluid is prepared, high-concentration water-based stamping fluid stock solution can be prepared firstly, and the stock solution is diluted to the required solid content by water when in use.
Wherein, the stock solution of the water-based punching fluid preferably comprises the following components in percentage by mass: 14-18% of organic alkali, 10-15% of extreme pressure agent, 5-15% of oiliness agent, 0.3-0.8% of corrosion inhibitor, 0.1-0.2% of complexing agent, 0.15-0.4% of defoaming agent and the balance of water.
