Anti-corrosion and anti-wear modification method of anti-freezing cooling liquid

Abstract

The invention discloses an anti-corrosion and anti-wear modification method of an anti-freezing cooling liquid. The modification method comprises the following steps: calcining expandable graphite ina muffle furnace, taking the calcined expandable graphite out for cooling, adding a hydrochloric acid solution, carrying out ultrasonic treatment, adding aniline, carrying out cooling in an ice bath,adding zinc phosphate, dropwise adding an ammonium persulfate solution under stirring, carrying out a reaction, performing standing, carrying out washing with water until a neutral state is reached, then performing washing with acetone, and carrying out vacuum drying to obtain zinc phosphate-polyaniline-graphene composite particles; diluting water-soluble polyurethane with deionized water to obtain a sizing agent, adding carboxylated carbon nanotubes, carrying out ultrasonic treatment, immersing desized basalt fibers in the sizing agent, and carrying out drying to obtain carbon nanotube-modified basalt fibers; and adding water into ethylene glycol, then adding floridosides, disodium hydrogen phosphate, sodium benzoate, sebacic acid, benzotriazole, borax, the zinc phosphate-polyaniline-graphene composite particles and the carbon nanotube modified basalt fibers, and carrying out ultrasonic dispersion and uniform mixing so as to prepare the anti-corrosion anti-wear modified anti-freezingcooling liquid.

Description

technical field [0001] The invention belongs to the field of cooling fluids, and in particular relates to an anti-corrosion and wear-resistant modification method for antifreezing cooling fluids. Background technique [0002] Coolant, the full name should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing when parking in cold seasons, bursting the radiator and freezing the engine cylinder block, but we have to correct a misunderstanding, Antifreeze is not only used in winter, it should be used throughout the year. In the normal maintenance items of the car, the engine antifreeze needs to be replaced every year of driving. [0003] The coolant is composed of water, antifreeze, and additives. According to the composition of the antifreeze, it can be divided into alcohol type, glycerin type, and ethylene glycol type. Alcohol-type coolant uses ethanol (commonly known as alcohol) as antifreeze, which is ch...

AI Technical Summary

Problems solved by technology

However, pure ethylene glycol antifreeze coolant has the defects of poor corrosion resistance and wear resistance. Based on this, the present invention provides a method for modifying antifreeze and wear resistance of antifreeze coolant.

[0004] Basalt fiber has the advantages of friction resistance, high temperature resistance, light weight, and high strength. However, the surface of basalt fiber is inert, and the reinforced composite material has the following problems: the interface between basalt fiber and matrix is ​​weak, and the modification efficiency is low. And the modification method damages the fiber body strength, etc.
