Description
Technical Field
The invention belongs to the technical field of chemical cleaning agents, and particularly relates to an environment-friendly stainless steel cleaning agent and a method for cleaning stainless steel parts.
Background
Generally, after a stainless steel part is machined and formed, fingerprints, dust, machining oil, cutting fluid, grease and other organic and inorganic solid particles are attached to the surface of the part, and the part is corroded and worn, particularly a workpiece with welding spots and a stainless steel part which is poor in corrosion resistance and generates rust scale, so that an efficient cleaning agent is required to remove the impurities after the part is machined.
Currently, high efficiency cleaners include solvent-based cleaners and water-based cleaners. The solvent type cleaning agent comprises gasoline, kerosene, tetrachloroethylene, trichloroethylene, dichloromethane, freon, hydrocarbon solvents and the like, and the solvent type cleaning agent has the problems of flammability, explosiveness, high toxicity, damage to atmospheric ozone, solvent recovery treatment and the like, and has higher recovery cost; the water-based cleaning agent for the stainless steel parts mainly comprises a neutral or weakly alkaline cleaning agent, but both the neutral or weakly alkaline cleaning agent and the weakly alkaline cleaning agent have the defect of poor oil stain removal effect, and although part of the cleaning agent obtains good oil stain removal effect because of adding a surface active ingredient containing Nonylphenol (NP) or Octylphenol (OP), the NP and OP surfactants are difficult to biodegrade, and the environment is damaged difficultly after long-term large-scale use. However, the cleaning effect is not satisfactory for cleaning processing lubricating oil such as high-viscosity drawing oil and silicone oil, and for cleaning stainless steel surface having carbon deposit and dry oil stain on the surface. For cleaning such oil stains and stainless steel with rust stains and welding spots, most of the cleaning agents are strong-acid cleaning agents in the market at present. Hydrochloric acid, sulfuric acid and other strong acids corrode the surface of stainless steel to some extent, and the phosphorus-containing acidic cleaning agent has influence on aquatic organisms and is difficult to degrade. Therefore, the environment-friendly stainless steel cleaning agent is produced at the same time.
Disclosure of Invention
The invention mainly aims to provide an environment-friendly stainless steel cleaning agent and a method for cleaning stainless steel parts.
In order to achieve the purpose, the invention provides an environment-friendly stainless steel cleaning agent which comprises the following components in percentage by weight:
preferably, the organic acidic substance is one or more of glycolic acid, methanesulfonic acid, gluconic acid and citric acid.
Preferably, the chelating dispersant is one or more of sodium gluconate, sodium citrate, sodium polyacrylate and sodium salt of a propylene-maleic copolymer.
Preferably, the isomeric alcohol polyoxyethylene ether is one or more of XP-70, 1309, T0-8 and KT-08.
Preferably, the non-ferrous metal protective agent is a copper metal protective agent and/or an aluminum metal protective agent; wherein the copper metal protective agent is one or more of benzotriazole, furfural and mercaptobenzotriazole; the aluminum metal protectant is a phosphate and/or siloxane type aluminum protectant.
Preferably, the corrosion inhibitor is one or more of thiourea, hexamethylenetetramine and organic nitrogen-containing compounds.
The method for cleaning the stainless steel parts by using the environment-friendly cleaning agent for the stainless steel comprises the following steps:
diluting the stainless steel environment-friendly cleaning agent by 10-50 times with water to obtain a diluent;
placing the stainless steel part in a diluent at the temperature of 20-50 ℃ for cleaning;
and taking out the stainless steel part, rinsing the stainless steel part in water, and drying the part.
When cleaning, one or more of the following cleaning methods are adopted:
firstly, heating the diluent to 40-50 ℃, then putting the stainless steel parts into the diluent, and soaking the stainless steel parts for 10-30 min;
secondly, heating the diluent to 40-50 ℃, putting the stainless steel parts into the diluent, and ultrasonically cleaning the stainless steel parts for 2-10 min;
thirdly, heating the diluent to 20-40 ℃, putting the diluent into a stainless steel part, and scrubbing the stainless steel part by using a brush or a towel until stains are removed.
The cleaning agent can quickly penetrate into the inner surfaces of oil stains and rust scales by utilizing the synergistic effect of the isomeric alcohol polyoxyethylene ether, akco 226SA, the fatty alcohol polyoxyethylene ether penetrant and the organic acid substance, so that the oil stains are quickly emulsified, the rust scales are separated from the surfaces of parts, and the cleaning agent has a high-efficiency cleaning effect. And because the nonferrous metal protective agent and the corrosion inhibitor are added, the cleaning agent can not damage the surface of the part such as color change, corrosion and the like, and has good cleaning effect and protective effect on part of nonferrous metals. In addition, all the components of the cleaning agent are biodegradable raw materials, so that the cleaning agent does not pollute the environment.
In summary, the beneficial effects of the invention are as follows:
(1) the cleaning agent is an acidic water-based cleaning agent, has a strong cleaning effect, is particularly suitable for cleaning inorganic and organic attachments such as processing oil, fingerprints, rust scale, welding spots and the like attached to the surface of stainless steel metal, has high cleaning speed and good cleaning effect, and does not have the problems of color change and corrosion on part of nonferrous metal.
(2) The raw materials are environment-friendly, and the environment is not polluted.
(3) The cleaning agent disclosed by the invention is used for cleaning, and has the advantages of simplicity and easiness in operation, small using amount of the cleaning agent and good cleaning effect.
Detailed Description
The invention relates to an environment-friendly stainless steel cleaning agent which comprises the following components in percentage by weight: 5-20% of an organic acidic substance, 1-5% of a chelating dispersant, 5-10% of isomeric alcohol polyoxyethylene ether, 3-10% of Aksu 226SA, 2-8% of fatty alcohol polyoxyethylene ether, 0-2% of a metal protective agent, 0-2.5% of a corrosion inhibitor and water.
The organic acidic substance is used for providing a weakly acidic environment, and the cleaning agent is easier to permeate into oil stains in the acidic environment and has stronger cleaning effect on rust stains and oil stains with high viscosity. In specific implementation, the organic acidic substance can adopt one or more of glycolic acid, methanesulfonic acid, gluconic acid and citric acid, and glycolic acid is preferred.
The chelating dispersant has chelating and dispersing functions and is used for improving the stability of the cleaning agent. Sodium gluconate is a preferred chelating dispersant because it is readily soluble in water, neutral, and has chelating and dispersing effects.
The isomeric alcohol polyoxyethylene ether is a biodegradable nonionic surfactant and has the functions of emulsification, permeation and decontamination. XP-70, 1309, T0-8 and KT-08 are isomeric alcohol polyoxyethylene ethers with four different structures, and the cleaning agent of the invention adopts TO-8 and KT-08, so that the oil removing and cleaning effect is more prominent. The TO-8 has outstanding emulsifying performance and good permeability. KT-08 has better permeability and low foaming property. When the cleaning agent is sprayed TO the oil stain on the surface of the part TO be cleaned, the TO-8 can rapidly permeate into the oil stain TO further emulsify the oil stain, so that the oil stain is stripped from the surface of the part, and the efficient cleaning effect is achieved.
Aksuo 226SA is a mixture of cationic and nonionic surfactants, has extremely low surface tension, and has very outstanding low temperature heavy oil fouling removal properties, but has the disadvantage of being relatively expensive. Therefore, the Acksu 226SA and the isomeric alcohol polyoxyethylene ether are compounded, so that the raw material cost is reduced, and oil can be removed cooperatively.
The fatty alcohol-polyoxyethylene ether is used as a penetrating agent for promoting the cleaning agent to penetrate into the oil stain, and JFC can be adopted in specific implementation.
The invention does not limit the concrete variety of the non-ferrous metal protective agent, and can be any conventional non-ferrous metal protective agent and can also be the compound of various conventional organic metal protective agents. Adopts a copper metal protective agent and/or an aluminum protective agent which can be mutually dissolved with other components and can be biologically degraded. By adding the non-ferrous metal protective agent, the corrosivity of the cleaning agent on non-ferrous metal parts can be reduced, and the damage of color change and corrosion on the surfaces of the parts is avoided.
In specific implementation, the copper metal protective agent can adopt one or more of benzotriazole, furfural and mercaptobenzotriazole, and benzotriazole with the mass content of not less than 99% is preferred; the aluminum metal protective agent can be phosphate, siloxane type aluminum protective agent or aluminum metal protective agent formed by compounding phosphate and siloxane type aluminum protective agent, preferably siloxane type aluminum protective agent, and the mass concentration of active ingredients in the siloxane type aluminum protective agent is not less than 40%, such as NEUF815 type aluminum material corrosion inhibitor.
In specific implementation, the corrosion inhibitor is one or more of thiourea, hexamethylenetetramine and organic nitrogen-containing compounds, the specific commodity of the hexamethylenetetramine can be urotropin, and the specific commodity of the organic nitrogen-containing compounds can be LAN-826. Among them, thiourea has good water solubility, no obvious special odor and relatively stable in the stock solution of the cleaning agent, and therefore, thiourea is a preferable corrosion inhibitor.
