Description

Technical Field

[0001] The invention relates to the technical field of degreasing agents, in particular to a non-ionic water-based degreasing agent for removing dirt from titanium alloy chips. Background Art

[0002] In the titanium alloy processing industry, waste materials account for 35% of the total materials. Dirt in the waste materials must be thoroughly cleaned and restored to the state before processing so that they can be re-smelted to obtain titanium alloy materials with excellent performance. This puts higher requirements on surface cleaning. Traditional chemical cleaning can no longer meet the requirements, and new cleaning products need to be developed.

[0003] The cutting fluid used in the titanium alloy processing process includes lubricating grease, mainly mineral oil, and a small amount of animal and vegetable oil; surfactants such as petroleum sodium sulfonate to reduce friction; silane emulsifiers, alkyl ethyl trimethyl ether emulsifiers, modified ethylene glycol emulsifiers to reduce oil-water interfacial tension; and chlorine, sulfur, and phosphorus additives, organic amines, chlorinated esters, and dithiophosphates to increase the viscosity and fluidity of the cutting fluid and improve cutting efficiency. A series of complex components constitute the main dirt on the surface of the chips, so a targeted degreasing agent that can effectively clean the surface of titanium alloys is needed. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a non-ionic water-based degreasing agent for removing dirt from titanium alloy chips. The non-ionic water-based degreasing agent has the advantage of being able to effectively clean the surface of titanium alloys, and solves the problem that the cutting fluid used in the titanium alloy processing process includes lubricating grease, mainly mineral oil, and a small amount of animal and vegetable oils; surfactants such as sodium petroleum sulfonate to reduce friction; silane emulsifiers, alkyl ethyl trimethyl ether emulsifiers, and modified ethylene glycol emulsifiers to reduce oil-water interfacial tension; and chlorine, sulfur, and phosphorus additives, organic amines, chlorinated esters, and dithiophosphates to increase the viscosity and fluidity of the cutting fluid and improve cutting efficiency. A series of complex components constitute the main dirt on the chip surface, so a targeted degreasing agent that can effectively clean the titanium alloy surface is needed.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of being able to effectively clean the surface of titanium alloy, the present invention provides the following technical solution: a non-ionic water-based degreasing agent for removing dirt from titanium alloy chips, comprising the following raw materials in proportion by weight: 70%-80% water, 4%-6% potassium hydroxide, 1%-2% disodium ethylenediaminetetraacetic acid, 1%-3% urea, 1%-2% borax, 0.2%-0.4% sodium benzoate, 0.3%-0.6% water glass, 5%-9% fatty alcohol polyoxyethylene ether, 4%-6% alkylphenol polyoxyethylene ether, 3%-6% oleic acid, 2%-3% triethanolamine and 0.5%-1.5% ethanol.

[0008] A method for preparing a non-ionic water-based degreasing agent for removing dirt from titanium alloy chips, comprising the non-ionic water-based degreasing agent for removing dirt from titanium alloy chips, and further comprising the following steps:

[0009] S1. Weigh 70%-80% water and 4%-6% potassium hydroxide and stir them in a stirring bucket;

[0010] S2, weigh 1%-2% of disodium ethylenediaminetetraacetate, 1%-3% of urea, 1%-2% of borax, 0.2%-0.4% of sodium benzoate and 0.3%-0.6% of water glass and add them into the mixing tank;

[0011] S3. After stirring to a certain extent, add 5%-9% of fatty alcohol polyoxyethylene ether, 4%-6% of alkylphenol polyoxyethylene ether, 3%-6% of oleic acid, 2%-3% of triethanolamine and 0.5%-1.5% of ethanol to prepare MS-205 degreasing agent.

[0012] Preferably, the mass ratio of disodium ethylenediaminetetraacetate, urea and borax is 1:2:1.

[0013] Preferably, the mass ratio of sodium benzoate to water glass is 2:3.

[0014] Preferably, the mass ratio of fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether, oleic acid and triethanolamine is 6:4:3:2.

[0015] Preferably, the mixing barrel is always stirring when adding raw materials, so that all raw materials are fully stirred until uniform.

[0016] Preferably, the stirring time of the stirring barrel is between 1-2 hours.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a non-ionic water-based degreasing agent for removing dirt from titanium alloy chips, which has the following beneficial effects:

[0019] 1. The non-ionic water-based degreasing agent for removing dirt from titanium alloy chips. The MS-205 degreasing agent prepared by the present invention is a product that is optimized and compounded with non-ionic surfactants, chelating agents, pH regulators, solubilizers, and cleaning aids as main components; the pH regulator in the degreasing agent, such as potassium hydroxide, converts animal and plant oils in the dirt into soap substances that are easy to clean through its alkaline components, thereby promoting the cleaning process; non-ionic surfactants, such as fatty alcohol polyoxyethylene ethers and alkylphenol polyoxyethylene ethers, will not dissociate into ionic forms in water, so they are less affected by water quality and have higher stability; one end of the non-ionic surfactant molecule has a lipophilic functional group, and the other end has a hydrophilic functional group. This unique amphiphilic property enables it to effectively insert into oil stains composed of mineral oil, silane emulsifier, alkyl ethyl trimethyl ether emulsifier, modified ethylene glycol emulsifier, organic amine, chlorinated ester and dithiophosphate. For example, the molecular structure of triethanolamine oleate contains lipophilic groups and hydrophilic groups, which enables them to form a thin film at the oil-water interface, thereby playing an emulsifying role and helping to peel off the oil stains from the metal surface. Solubilizers, such as urea, contain polar groups such as carbonyl and amino groups, which give them a high degree of hydrophilicity. Urea combined with the hydrophilic part of the non-ionic surfactant in the degreaser helps to stably disperse the stripped dirt in the water, ensuring its complete separation from the metal surface.

[0020] 2. The non-ionic water-based degreasing agent for removing dirt from titanium alloy chips and high-efficiency chelating agents such as disodium EDTA can effectively remove oxides, salts and other impurities on the surface of chips through its chelating effect, further enhancing the degreasing effect; at the same time, the chelating agent and the cleaning aid work synergistically to treat hard water components such as calcium, magnesium, barium, strontium in the water, reduce the hardness of the water, and improve the applicability and effectiveness of the MS-205 degreasing agent under different water quality conditions.

[0043] A nonionic water-based degreasing agent for removing dirt from titanium alloy chips comprises the following raw materials in proportion by weight: 70%-80% of water, 4%-6% of potassium hydroxide, 1%-2% of disodium ethylenediaminetetraacetate, 1%-3% of urea, 1%-2% of borax, 0.2%-0.4% of sodium benzoate, 0.3%-0.6% of water glass, 5%-9% of fatty alcohol polyoxyethylene ether, 4%-6% of alkylphenol polyoxyethylene ether, 3%-6% of oleic acid, 2%-3% of triethanolamine and 0.5%-1.5% of ethanol.

[0044] Specifically, pH adjusters include potassium hydroxide: which, through its alkaline component, converts animal and plant oils in dirt into soapy substances that are easy to wash off, thus facilitating the cleaning process;

[0045] Non-ionic surfactants, including fatty alcohol polyoxyethylene ethers and alkylphenol polyoxyethylene ethers: they will not dissociate into ionic forms in water, so they are less affected by water quality and have high stability; one end of the molecular structure has a lipophilic functional group, and the other end has a hydrophilic functional group. This unique amphiphilic property enables it to effectively insert into oil stains composed of mineral oil, silane emulsifiers, alkyl ethyl trimethyl ether emulsifiers, modified ethylene glycol emulsifiers, organic amines, chlorinated esters and dithiophosphates, and help the oil stains to be peeled off from the metal surface;

[0051] The chelating agent and the cleaning aid work together to treat the hard water components in the water, reduce the hardness of the water, and improve the applicability and effectiveness of the degreasing agent under different water quality conditions;

[0052] The combination of solubilizer and nonionic surfactant helps to stably disperse the stripped dirt in the water, ensuring that it is completely separated from the metal surface.

[0053] Specifically, the non-ionic water-based degreasing agent for removing dirt from titanium alloy chips prepared by the present invention has been comprehensively considered in terms of safety to ensure its safety during use and minimize its impact on the environment. First, from the perspective of physicochemical stability, the degreasing agent has good stability under appropriate storage conditions (such as stored in a cool and dry place, away from heat sources and fire sources), which can ensure its long-term preservation without losing its functional properties. Secondly, from the perspective of biodegradability, the non-ionic surfactants in the degreasing agent have good biodegradability, which means that they can be decomposed by the action of microorganisms in the natural environment, reducing the lasting impact on the environment. In addition, the degreasing agent does not contain heavy metals or other harmful substances, so it has less impact on human health, but appropriate personal protective equipment must still be worn when using it to avoid direct contact with the skin and eyes. Finally, considering the impact on the environment, the waste liquid after use must be treated in accordance with local regulations to avoid pollution of the water body.

[0054] Specifically, the non-ionic water-based degreasing agent for removing dirt from titanium alloy chips prepared by the present invention has shown good benefits in terms of raw material cost, use cost and maintenance cost from an economic point of view. First, the raw materials used in the degreasing agent are mostly common and relatively low in cost, and the cost can be further reduced by bulk purchasing and the like. Secondly, considering that the recommended preparation concentration of the degreasing agent when in use is 5%, a high degreasing rate can be guaranteed (as shown in the embodiment), thereby reducing unnecessary waste. Thirdly, since the degreasing agent has good stability, the need for frequent replacement is reduced and maintenance costs are reduced. Overall, considering its high efficiency and low corrosiveness, it can not only effectively reduce subsequent processing costs, but also improve the recycling rate of titanium alloy chips, thereby bringing significant economic benefits.
