Composite antioxidant scale-inhibiting anticoagulant

Abstract

The invention relates to a composite antioxidant scale-inhibiting anticoagulant. The composite antioxidant scale-inhibiting anticoagulant comprises the following components: 24-36 weight parts of polyacrylate(high carbon alcohol), 25-36 weight parts of an olefin copolymer, 8-11 weight parts of isooctyl nitrate, 8-12 weight parts of methyl adipate, 2-5 weight parts of a polyether amine salt, 10-15weight parts of cyclohexane, 8-12 weight parts of trimethylbenzene, 2-3 weight parts of zinc dialkyl dithiophosphate, 0.5-0.8 weight part of zinc di(primary octyl) dithiophosphate, 1-1.8 weight partsof basic zinc di(primary octyl) dithiophosphate, 10-12 weight parts of water, 8-11 weight parts of organic amine, 2-6 weight parts of diethylene glycol, 3-5 weight parts of alcohol, 3-5.5 weight partsof phosphorus pentoxide, and 2-2.8 weight parts of isopropanol. The composite antioxidant scale-inhibiting anticoagulant provided by the invention can improve the low-temperature fluidity of fuel oiland ensure smooth cold start of the engine, is added with organic amine to neutralize acidic substances, and increases the anticorrosion effect of the pipe wall metal surface film. The detergent provided by the invention can be used as a preservative for circulating water, has descaling, dispersing and sterilizing functions, and has a corrosion inhibition rate of greater than or equal to 98%.

Description

technical field [0001] The invention relates to the field of fuel additives, in particular to a composite anti-oxidation, anti-scaling and anti-coagulant agent. Background technique [0002] The reason why the fuel solidifies at a lower temperature is that the fuel contains a certain amount of wax (that is, n-alkanes). Usually, the content of n-alkanes in the fuel is about 15%-30%. When the fuel is cooled, the wax crystals It will grow rapidly, and first form planar crystals. These crystals are connected to each other to form a three-dimensional network structure, enclosing oil in it, making it lose its fluidity and appear in a solidified state. When the fuel engine is working, the fuel is sprayed into the cylinder through the coarse and fine filters, and then through the high-pressure pump and fuel injector. When the fuel temperature drops to the cold filter point temperature, the formed wax crystals will block the filter and affect the normal oil supply of the oil circuit...

Problems solved by technology

When the fuel temperature drops to the cold filter point temperature, the formed wax crystals will block the filter and affect the normal fuel supply of the oil circuit, thereby affecting the normal operation of the engine

[0003] During the long-term use of the car, deposits are easily formed on the carburetor, nozzle, intake valve, combustion chamber and other parts, resulting in reduced engine performance, increased fuel consumption, worsened exhaust emissions, and polluted the environment
