Description

Technical Field

[0001] The invention relates to the technical field of internal combustion engine cooling, in particular to a multifunctional composite agent for high-efficiency wear reduction, lubrication and cooling of an internal combustion engine lubrication system. Background Art

[0002] An internal combustion engine is an engine that generates power by burning fuel. It is one of the most widely used engines in modern industry and transportation. The working principle of an internal combustion engine is to use fuel to burn in the presence of oxygen to generate high-temperature and high-pressure gas to drive the piston movement, thereby converting it into mechanical energy. The working cycle of an internal combustion engine consists of intake, compression, combustion and expansion, and exhaust. In order to ensure the stable operation of the internal combustion engine, it is necessary to add lubricant compounds to it. Reasonable use of lubricant compounds and regular maintenance can improve the performance of the internal combustion engine and extend the service life of the internal combustion engine.

[0003] After searching, it was found that most of the lubricating oil compounding agents in the prior art mainly focus on the lubrication part, but not the cooling part. However, the viscosity of the lubricating oil in the lubricating oil compounding agent will decrease with the increase of temperature. The temperature change affects the molecular structure and movement of the lubricating oil. When the temperature rises, the movement speed of the lubricating oil molecules increases, and the friction between molecules decreases, causing the lubricating oil to become thinner. In addition, when the lubricating oil works at high temperature, it is easy to accelerate oxidation and deterioration, generating acidic substances and some insoluble substances and sediments, such as sludge and paint film. The oxidation of oil products will also generate some insoluble substances and sediments, which accelerate the deterioration of the lubricating oil and shorten the service life of the oil products. When the temperature exceeds 60°C, the service life of the lubricating oil will be halved for every 10°C increase. If the lubricating oil temperature is too high, the viscosity of the lubricating oil will decrease, resulting in a thinner lubricating oil film. If the oil film thickness is too thin, it is not enough to provide lubrication protection, or it is difficult to form a complete lubricating oil film on the metal surface, and it cannot provide good protection, so the parts are more susceptible to wear and scratches.

[0004] In view of this, the present application proposes a multifunctional composite agent for high-efficiency wear reduction, lubrication and cooling in the lubrication system of an internal combustion engine, so as to keep the lubricating oil composite agent working within a suitable temperature range. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a multifunctional composite agent for high-efficiency wear reduction, lubrication and cooling of the lubrication system of an internal combustion engine, which solves the problem that most products in the prior art mainly focus on the lubrication part but not the cooling part, resulting in a short service life and poor lubrication and protection effect.

[0006] To achieve the above objectives, the present invention is implemented through the following technical scheme: an internal combustion engine lubrication system high-efficiency wear-reducing, lubricating and cooling multifunctional composite agent, comprising the following raw materials in parts by weight: 70-90 parts of base oil, 1-3 parts of detergent dispersant, 0.5-3 parts of thiophosphate butyl octyl zinc salt antioxidant and corrosion inhibitor, 0.5-1.5 parts of thiophosphate butyl octyl molybdenum salt friction modifier, 0.3-0.5 parts of Sanwo poly-energy lubricating oil improver, 0.3-0.5 parts of heat transfer oil, 3-5 parts of graphene additives, 1-3 parts of extreme pressure anti-wear agent, 0.5-1.5 parts of oiliness agent, 0.5-1.5 parts of metal deactivator, 0.3-0.5 parts of viscosity index improver, 1-3 parts of rust inhibitor, 1-3 parts of pour point depressant, and 1-3 parts of anti-foaming agent.

[0007] Preferably, the base oil is a mixture of at least one or more of Group I base oil, Group II base oil, Group III base oil and synthetic base oil.

[0008] Preferably, the number of graphene layers in the graphene additive is 3-10.

[0009] Preferably, the compound of the extreme pressure anti-wear agent is an organic chloride.

[0010] Preferably, the rust inhibitor is barium sulfonate, sodium sulfonate or alkylbenzene sulfonate.

[0011] Preferably, 70 parts of base oil, 1 part of detergent dispersant, 0.5 parts of zinc octyl thiophosphate antioxidant and corrosion inhibitor, 0.5 parts of molybdenum octyl thiophosphate friction modifier, 0.3 parts of Sanwo poly-lubricant improver, 0.3 parts of thermal oil, 3 parts of graphene additive, 1 part of extreme pressure anti-wear agent, 0.5 parts of oiliness agent, 0.5 parts of metal deactivator, 0.3 parts of viscosity index improver, 1 part of rust inhibitor, 1 part of pour point depressant, and 1 part of anti-foaming agent.

[0012] Preferably, 90 parts of base oil, 3 parts of detergent dispersant, 3 parts of zinc octyl thiophosphate antioxidant and corrosion inhibitor, 1.5 parts of molybdenum octyl thiophosphate friction modifier, 0.5 parts of Sanwo poly-lubricant improver, 0.5 parts of thermal oil, 5 parts of graphene additive, 3 parts of extreme pressure anti-wear agent, 1.5 parts of oiliness agent, 1.5 parts of metal deactivator, 0.5 parts of viscosity index improver, 3 parts of rust inhibitor, 3 parts of pour point depressant, and 3 parts of anti-foaming agent.

[0013] Beneficial Effects

[0014] The present invention provides a multifunctional composite agent for high-efficiency wear reduction, lubrication and cooling of an internal combustion engine lubrication system, which has the following beneficial effects:

[0015] The added heat-conducting oil can make the composite agent have efficient heat conduction performance, lower operating pressure and wide operating temperature range. In addition, the complementary effect of Sanwo Poly-Energy Lubricant Improver and graphene additive can effectively assist heat dissipation, ensuring that graphene can be firmly adsorbed on the friction surface. Since graphene is evenly dispersed in the lubricating oil, the electrons in the graphene can move quickly. When they interact with the heat generated by the internal combustion engine at work, they will take away part of the heat energy of the internal combustion engine, further reduce the temperature, and achieve cooling and lubrication of the internal combustion engine.

[0016] At the same time, Sanwo's lubricant improver, graphene additives and rust inhibitors will also complement the extreme pressure anti-wear agents, so that the overall temperature of the composite agent will always be guaranteed not to be too high, which will create conditions for the use of organic chlorides in extreme pressure anti-wear agents, avoiding metal corrosion and rust under high temperature conditions, thereby ensuring the use effect while reducing costs. DETAILED DESCRIPTION

[0017] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Embodiment 1:

[0019] The invention provides a technical solution: a multifunctional composite agent for high-efficiency wear reduction, lubrication and cooling of an internal combustion engine lubrication system, comprising the following raw materials in parts by weight: 70-90 parts of base oil, 1-3 parts of a detergent dispersant, 0.5-3 parts of a zinc salt of thiophosphate butyl octyl antioxidant and corrosion inhibitor, 0.5-1.5 parts of a friction modifier of a molybdenum salt of thiophosphate butyl octyl, 0.3-0.5 parts of a Sanwo poly-energy lubricating oil improver, 0.3-0.5 parts of a heat transfer oil, 3-5 parts of a graphene additive, 1-3 parts of an extreme pressure anti-wear agent, 0.5-1.5 parts of an oiliness agent, 0.5-1.5 parts of a metal deactivator, 0.3-0.5 parts of a viscosity index improver, 1-3 parts of a rust inhibitor, 1-3 parts of a pour point depressant, and 1-3 parts of an anti-foaming agent;

[0020] Among them, the added thermal oil can make the composite have efficient thermal conductivity, lower operating pressure and a wide operating temperature range, and it can effectively assist heat dissipation in combination with Sanwo Poly-Energy lubricant improver and graphene additives. And because graphene is evenly dispersed in the lubricant, the electrons in the graphene can move quickly. When they interact with heat, they will take away part of the heat energy, further reduce the temperature and achieve cooling.

[0021] This embodiment is further configured that the base oil is a mixture of at least one or more of Class I base oil, Class II base oil, Class III base oil, and synthetic base oil;

[0022] By adding detergent dispersants, the dispersion stability in the base oil can be improved, thereby improving the overall effectiveness of the compound.

[0023] This embodiment is further configured such that the number of graphene layers in the graphene additive is 3-10 layers;

[0024] The performance of lubricating oil can be improved by adding graphene additives. Since the number of graphene layers in the selected graphene additives is 3-10, and graphene has the problem of mutual attraction, adding Sanwo Poly-Energy lubricating oil improver for complementation can make the graphene evenly dispersed in the lubricating oil, effectively overcoming the problem of mutual attraction of graphene and ensuring that the graphene can be firmly adsorbed on the friction surface.

[0025] This embodiment is further configured such that the compound of the extreme pressure anti-wear agent is an organic chloride;

[0026] The extreme pressure anti-wear agent compound used is an organic chloride, which is relatively low in cost and difficulty in preparation. At the same time, since Sanwo Poly-Energy lubricant improver, graphene additives and rust inhibitors are added to the composite agent, the overall temperature of the composite agent can always be guaranteed not to be too high, which creates conditions for the use of organic chlorides and prevents them from causing metal corrosion and rust under high temperature conditions, thereby ensuring the use effect while reducing costs.

[0027] This embodiment is further configured such that the rust inhibitor is barium sulfonate, sodium sulfonate or alkylbenzene sulfonate;

[0028] The rust inhibitors using barium sulfonate, sodium sulfonate or alkylbenzene sulfonate components can be better matched with the extreme pressure anti-wear agent, thereby ensuring the overall rust and corrosion resistance of the composite agent.

[0029] In the present application, the added heat-conducting oil can make the composite have efficient thermal conductivity, lower operating pressure and a wide operating temperature range, and with the complementarity of Sanwo poly-energy lubricant improver and graphene additive, it can effectively assist heat dissipation, ensuring that the graphene can be firmly adsorbed on the friction surface, and because the graphene is evenly dispersed in the lubricant, the electrons in the graphene can move quickly. When they interact with heat, they will take away part of the heat energy, further reduce the temperature and achieve cooling. At the same time, Sanwo poly-energy lubricant improver, graphene additives and rust inhibitors will also complement the extreme pressure anti-wear agent, so that the overall temperature of the composite can always be guaranteed not to be too high, which creates conditions for the use of organic chlorides in extreme pressure anti-wear agents, avoiding metal corrosion and rust under high temperature conditions, thereby ensuring the use effect while reducing costs.
