Description
Technical Field
The invention relates to the technical field of metal surface treatment, in particular to a modified graphene oxide degreaser and a preparation method and application thereof.
Background
When metals are deeply processed, the surfaces of the metals are usually adhered with oil stains to different degrees, and the oil stains generally comprise cutting fluid, antirust oil, animal and vegetable oil, grinding paste, dust and the like. The quality of the oil removal effect directly influences the subsequent metal processing and the product quality, and for aluminum alloy products, oil removal is the first important key process of anodic oxidation treatment and surface spraying treatment of the aluminum alloy products, and incomplete oil removal directly influences the operation of the next process, even can pollute the subsequent production line, and causes the quality problems of oxide film defects, uneven film layers, surface pinholes and coating adhesive force reduction of the aluminum alloy products.
At present, most of the components of the oil removing agent sold in the market generally contain toxic substances with different degrees, so that the oil removing agent is easy to damage the environment and operators; meanwhile, the problems of long cleaning time, low cleaning efficiency and poor cleaning effect exist, and the subsequent processing of metal products is directly influenced.
Disclosure of Invention
The present invention is directed to solving the problems described above. The invention aims to provide a modified graphene oxide degreaser which can quickly and efficiently carry out degreasing treatment on a metal sample; meanwhile, the components of the oil removing agent cannot damage the surface of the metal sample, so that the subsequent processing of the metal product is guaranteed; can be used for the surface oil removal treatment of various stainless steel products, aluminum alloy products and copper alloy products.
According to one aspect of the invention, the invention provides a modified graphene oxide degreaser, which comprises 5-25 parts by weight of modified graphene oxide, preferably 8-20 parts by weight of modified graphene oxide. Graphene oxide is an oxide of graphene, has a planar structure similar to graphene, and has a large number of active groups on the surface, such as active functional groups like hydroxyl (-OH), epoxy [ -C (O) C- ], carboxyl (-COOH), and the like, so that the graphene oxide has excellent performance characteristics such as good hydrophilicity, compatibility, dispersibility, chemical reaction activity, surface wettability, and the like, and meanwhile, provides a congenital excellent condition and basis for surface modification research.
Graphene oxide itself has a large number of hydrophilic groups such as hydroxyl groups, epoxy groups, and carboxyl groups, and has good water solubility, but graphene oxide itself lacks a lipophilic structure, and thus graphene oxide does not provide conditions for preparing an oil remover. Compared with graphene oxide, the modified graphene structure provided by the invention has hydrophilic groups and has a lipophilic structure, namely alkyl benzene methylamine; the modified graphene oxide has a unique structure and has hydrophilicity and lipophilicity, so that the modified graphene oxide has the conditions required for preparing the oil removing agent.
In the invention, modified graphene oxide, specifically alkylbenzylamine modified graphene oxide is added into the oil removing agent, and the surface of the graphene oxide has rich active group epoxy [ -C (O) C-]Easily react with alkyl benzene methylamine organic Compounds (CH)3-(CH2)n-C6H4-NH2) Nucleophilic reaction is carried out. The graphene oxide modified by the alkylbenzene methylamine has a hydrophilic and lipophilic amphoteric structure, an oleophilic structure group (the alkylbenzene methylamine) is mainly used for coating various oil stains on the surface of a metal to enable the oil stains to be separated from the surface of the metal, and the hydrophilic structure (the graphene oxide) has the function of increasing the solubility of a solute, further reduces the interfacial surface tension of the oil stains, and has a synergistic effect with the oleophilic group to enhance the oil removal effect. Alkyl benzene methyl amine (CH)3-(CH2)n-C6H4-NH2) N is 6 to 10; because the long-chain structure of the alkyl benzylamine group in the interval is the closest to the structure of the common oil stain molecules, the alkyl benzylamine group structure of n in the interval is similar to that of the alkyl benzylamine group structure of the oil stain molecules according to the principle of' similarity and compatibilityThe oil stain similarity and intermiscibility effect is optimal. If n is less than or equal to 4, the corresponding alkyl benzyl amino group has lower similarity with the structure of the common oil stain; if the n value is more than or equal to 11, the difficulty of the nucleophilic reaction between the alkylbenzylamine group and the graphene oxide active group epoxy group is increased along with the gradual increase of the n value, and meanwhile, the similarity degree of the corresponding alkylbenzylamine structure and the common oil stain structure is gradually reduced.
The preparation method of the alkyl benzene methylamine modified graphene oxide comprises the following steps:
weighing graphene oxide (with the purity of more than or equal to 98%) and alkyl benzene methylamine according to a molar ratio of 1 (1.5-2.0), slowly filling the graphene oxide into a round-bottom flask, and dissolving and dispersing the graphene oxide by using anhydrous ethanol with the volume of 1/4-1/3 round-bottom flask; adding alkyl benzene methylamine, heating the mixed solution to 80-90 deg.C, and reacting with solution reflux device for 22-24 hr, preferably 24 hr. After the reaction is finished, slowly pouring the reaction liquid into a separating funnel, and separating out the residual alkylbenzene methylamine after the reaction; then heating and purifying the mixture of the alkylbenzylamine modified graphene oxide containing the ethanol at the temperature of 85-95 ℃.
If the reaction temperature is lower than 80 ℃, the nucleophilic reaction of the alkyl benzylamine and the epoxy group of the graphene oxide active group is influenced, and the actual yield is reduced; if the temperature is too low, even no reaction occurs. The reaction temperature is higher than 90 ℃, although the alkylbenzylamine modified graphene oxide required by the invention can be obtained, other by-products are increased due to the high temperature of the reaction system, and the actual yield is directly reduced.
The oil remover also comprises 1-15 parts by weight of organic alcohol, preferably 4-10 parts by weight; the organic alcohol is mainly used for swelling oil stains, so that the oil stains can be coated by the alkylbenzene methylamine modified graphene oxide. Wherein the organic alcohol is absolute ethyl alcohol, methanol or isopropanol. Compared with other organic alcohols, the organic alcohol selected by the invention has better mutual solubility with the modified graphene oxide and the organic active agent related to the system; the molecular structure of the graphene oxide has hydrocarbon and hydroxyl groups, so that the graphene oxide has weak polarity and can be used for fully dissolving oil stains in cooperation with the modified graphene oxide of the system. The organic alcohol content is too low, so that the modified graphene of the oil remover system cannot be well dispersed, and the comprehensive treatment effect of the oil remover system is reduced; if the organic alcohol content is too high, the content of other components of the present treatment system will be reduced, as will the overall oil removal effectiveness.
Meanwhile, the water-soluble organic solvent also comprises 0.5-10 parts by weight of organic active agent and 55-90 parts by weight of water, wherein the organic active agent is selected from one or more of polyethylene glycol 100, polyethylene glycol 200, polyethylene glycol 400, fatty alcohol-polyoxyethylene ether and polyoxyethylene octylphenol; the water is pure water or deionized water. Pure water or deionized water is used as a solvent for dissolving other components; the organic activator is mainly used for reducing the surface tension of the degreasing agent and the greasy dirt, improving the degreasing effect and finally achieving the purpose of quickly removing the greasy dirt on the metal surface. Further preferably, the organic active agent is 1 to 5 parts by weight; 65-87 parts of water.
In terms of the system, the selected organic active agent has a good surface tension adjusting effect in the oil removing agent system, and can effectively reduce the surface tension of the oil removing agent and oil stains of the system, so that the modified graphene oxide can better generate a similar and compatible effect with the oil stains, and the oil removing purpose is achieved. If the content of the organic active agent is too low, the surface tension of the modified graphene oxide and the oil stain cannot be well adjusted, and the oil removal effect is directly influenced; if the organic active agent content is too high, the content of other effective oil removal components in the system can be reduced, and the comprehensive oil removal effect of the system can be directly reduced.
The modified graphene oxide used in the invention has a good similar and compatible effect with common oil stains, the organic alcohol has good solubility to the modified graphene oxide of the oil stain system, the dispersion of the modified graphene in the oil stain system is increased, the organic active agent can effectively adjust the surface tension of the modified graphene oxide and the oil stains, the similar and compatible effect of the modified graphene oxide and the oil stains is increased, and the oil removing effect is powerfully improved.
According to another aspect of the invention, a preparation method of the modified graphene oxide oil remover is provided, which comprises the following steps:
1S: weighing a predetermined amount of water and adding the water into a container;
2S: weighing a predetermined amount of organic alcohol, adding into a container, and stirring at a stirring speed of 50-100rmp for 2-5min until the mixture is uniformly mixed;

comparative example 4 is a commercial degreaser.
The method for measuring the oil removal rate comprises the following steps:
1) taking a flat stainless steel sheet, wherein the specification of the invention is 20mm multiplied by 40mm multiplied by 2mm, putting the flat stainless steel sheet into a commercially available alkaline degreasing agent for degreasing for 10min at 60 ℃, taking out the flat stainless steel sheet, washing the flat stainless steel sheet clean by tap water, then leaching the flat stainless steel sheet by using purified water, drying the flat stainless steel sheet by using hot air, cooling and weighing the flat stainless steel sheet, and marking the flat stainless steel sheet as M0 (the;
2) dripping two drops of engine oil (Mofu lubricating oil) on the surface of the steel sheet, uniformly spreading the steel sheet by using a glass rod, suspending the steel sheet on a small beaker, and weighing the steel sheet as M1 (the weight of a test piece and oil stain);
3) and (3) suspending the steel sheet coated with lubricating oil in the oil removal agent to remove oil at room temperature, taking out the steel sheet after 10min, washing the steel sheet by tap water, then leaching the steel sheet by purified water, then drying the steel sheet by hot air, cooling and weighing the steel sheet, wherein the weight of the steel sheet is recorded as M2 (the mass of a test piece and residual oil stain).
4) The oil removal rate W was calculated as follows:
W＝(M1-M2)/(M1-M0)×100％
meanwhile, the oil removal rate of the commercially available metal cutting oil and the commercially available peanut oil is detected, and the determination method is the same as the above, and only the oil stain type in the second step is replaced by the commercially available metal cutting oil or the commercially available peanut oil.
