Description
Technical Field
The invention relates to the field of engine cooling liquid, in particular to organic engine cooling liquid containing carboxylated graphene and a preparation method thereof.
Background
The engine coolant is an indispensable component for maintaining the normal operation and running of the engine. The cooling liquid is a heat transfer medium of an engine cooling system and plays roles of cooling, corrosion prevention, scale prevention, freezing prevention and the like. The coolant is generally composed of water, antifreeze, corrosion inhibitor, scale inhibitor, colorant, defoamer, and the like. According to the composition of the corrosion inhibitor, the engine coolant can be divided into an inorganic coolant mainly comprising an inorganic salt corrosion inhibitor and an organic coolant mainly comprising an organic acid corrosion inhibitor.
At present, inorganic cooling liquid is mostly used in China, and the mainly applied inorganic salt corrosion inhibitors comprise silicate, borate, molybdate, phosphate and the like. The inorganic salt corrosion inhibitor is mainly used for passivating the surface of metal to generate a passivation film so as to achieve the purpose of protecting the metal. The inorganic salt corrosion inhibitor shows the following weaknesses in the application process: (1) the consumption speed is high, and additives need to be supplemented when the detergent is used; (2) the generated passivation film is thick and poor in heat conductivity, so that the heat dissipation performance is reduced; (3) the inorganic salt corrosion inhibitor has poor stability; (4) is not environment-friendly. The above disadvantages limit further widespread use of inorganic type cooling liquids.
The corrosion inhibitor of the organic cooling liquid which is used in the market mostly mainly comprises monobasic organic acid and dibasic organic acid. The organic acid type corrosion inhibitor changes the electrochemical property of the metal surface mainly through active adsorption on the metal surface, thereby preventing the metal corrosion. Compared with inorganic corrosion inhibitors, the consumption of the organic acid corrosion inhibitor is slow, and additives do not need to be supplemented. However, the organic acid corrosion inhibitor forms a thin (only a few nanometers) and non-dense adsorption film, which results in a less than ideal corrosion protection effect on tin and aluminum alloys, especially on cast aluminum heat transfer corrosion and aluminum pump cavitation corrosion.
Disclosure of Invention
The invention aims to solve the problem of providing the organic engine coolant containing the carboxylated graphene, wherein the carboxylated graphene and the organic acid corrosion inhibitor in the coolant have a synergistic effect, so that the coolant has an ideal anticorrosion effect on metal, and particularly has an obvious anticorrosion effect on cast aluminum heat transfer corrosion and aluminum pump cavitation corrosion.
In a first aspect, the invention provides an organic engine coolant containing carboxylated graphene, which comprises the following components in parts by weight: 30-95 parts of dihydric alcohol, 5-70 parts of deionized water, 0.03-3 parts of carboxylated graphene, 0.5-5.0 parts of organic acid corrosion inhibitor, 0.01-0.5 parts of azole corrosion inhibitor, 0.001-0.01 parts of defoaming agent and 0.01-0.05 parts of dye.
The carboxylated graphene is graphene with carboxyl functional groups on the surface.
Preferably, the glycol and the deionized water form a base liquid of the coolant, and the organic engine coolant containing the carboxylated graphene comprises the following components in parts by weight: 100 parts of base liquid, 0.03-3 parts of carboxylated graphene, 0.5-5.0 parts of organic acid corrosion inhibitor, 0.01-0.5 part of azole corrosion inhibitor, 0.001-0.01 part of defoaming agent and 0.01-0.05 part of dye.
Preferably, the organic engine coolant containing the carboxylated graphene comprises the following components in parts by weight: 55 parts of dihydric alcohol, 45 parts of deionized water, 0.2 part of carboxylated graphene, 3.5 parts of organic acid corrosion inhibitor, 0.15 part of azole corrosion inhibitor, 0.01 part of defoaming agent and 0.03 part of dye.
Preferably, the dihydric alcohol is one or more of ethylene glycol, 1, 2-propylene glycol and 1, 3-propylene glycol.
Preferably, the organic acid corrosion inhibitor comprises monocarboxylic acid and dicarboxylic acid; the monocarboxylic acid is C6～C10The dicarboxylic acid is C4～C10One or more of dicarboxylic acids (b).
Said C is6～C10The monocarboxylic acid is a carboxylic acid with only one carboxyl group and 6-10 carbon atoms in a carbon chain; said C is4～C10The dicarboxylic acid (b) is a carboxylic acid having 4-10 carbon atoms in the carbon chain and having two carboxyl groups.
Preferably, the azole corrosion inhibitor is one or two of benzotriazole and methylbenzotriazole.
Preferably, the defoaming agent is one of an organosilicon defoaming agent or an organic ether defoaming agent.
Preferably, the dye is at least one of acid lake blue, weak acid blue, rose bengal and bright yellow.
The mono-and di-organic carboxylic acids can form a protective film by adsorption on the metal surface, but the protective film is too thin and not dense, and is easy to corrode the metal, especially at high temperature and under gas impact. Therefore, the pure organic acid type cooling liquid has poor aluminum casting heat transfer corrosion and aluminum pump cavitation corrosion performance. The pure graphene has poor wettability with water, alcohol and a mixed solution thereof, and cannot be adsorbed on a metal surface to form a protective film. The surface carboxylated graphene is dissolved in water, alcohol and mixed solution thereof; more importantly, the carboxyl on the surface can be used for chemically bonding the carboxylated graphene and the metal so as to form an anti-corrosion protective film on the surface of the metal. However, the protective film of the pure carboxylated graphene has gaps and is not compact, and then the monobasic organic carboxylic acid corrosion inhibitor and the dibasic organic carboxylic acid corrosion inhibitor with proper proportion and proper carbon chain length are added, so that the carbon structure in the carboxylated graphene and the carbon chain (related to the length of the carbon chain and the branch structure of the carbon chain) of the organic acid corrosion inhibitor are well adsorbed and stacked on the metal surface through the synergistic effect of the monobasic organic carboxylic acid corrosion inhibitor and the dibasic organic carboxylic acid corrosion inhibitor, and the compact and flexible organic/inorganic hybrid anti-corrosion protective film is formed. The carboxylated graphene/organic acid protective film has good flexibility and quite high mechanical strength and hardness, so that the carboxylated graphene/organic acid protective film has a good resistance effect on impact pressure generated in the cavitation corrosion process; on the other hand, the formed carboxylated graphene/organic acid protective film has small thermal resistance with a metal matrix, is thin and compact, has good thermal conductivity, and has obvious corrosion prevention effect on heat transfer corrosion of cast aluminum.
Compared with the existing engine coolant, the coolant has the following beneficial effects:
the carboxylated graphene and the organic acid corrosion inhibitor in the cooling liquid generate a chemical bonding on the surface of the metal under the synergistic effect to form a thin, compact and high-heat-conductivity carboxylated graphene/organic acid protective film, so that the comprehensive anticorrosion effect on the metal is improved, and particularly the heat transfer corrosion of cast aluminum and the cavitation corrosion of an aluminum pump are improved;
