CN103773323A - Antifreezing fluid for automobile engine - Google Patents

Abstract

The invention discloses an antifreezing fluid for an automobile engine, relating to an antifreezing fluid for an automobile. The antifreezing fluid comprises the following components in parts by weight: 0-20 parts of propylene glycol, 0-20 parts of ethylene glycol, 0-20 parts of butanediol, 0-1 part of sodium phosphate, 0-1 part of sodium silicate, 0-30.0 parts of hydrochloride, 0-12 parts of borax, 0-18 parts of petroleum resin, 0-10 parts of glycine, 0-10 parts of 1,2-aminoazophenylene, 0-1.0 part of defoamer and 0-60 parts of water, wherein sodium phosphate, sodium silicate and borax are used as buffer agents; dimethicone or tributyl phosphate is used as the defoamer; dihydric alcohol is used as an antifreezing agent; 1,2-aminoazophenylene is used as a corrosion inhibitor; hydrochloride is one selected from alkaline metal, alkaline earth metal and third main group element hydrochlorides; glycine and petroleum resin are used as mildew preventives. The antifreezing fluid is capable of effectively preventing a circulation cooling fluid from being frozen, free of corrosion to a cooling system and incapable of freezing when used at low temperature of 40-50 DEG C below zero.

Description

A kind of automobile engine winterization fluid

Technical field

The present invention relates to a kind of automobile antifreeze solution, particularly relate to a kind of automobile engine winterization fluid.

Background technology

The engine-cooling system of internal combustion vehicle is a liquid-cooled sealing and circulating system being made up of cylinder, chuck and water tank.The working order of cooling system directly affects the normal operation of vehicle and the work-ing life of vehicle.Deicing fluid is the heat-eliminating medium of engine cycle cooling system, is mainly made up of frostproofer, inhibiter, defoamer, tinting material, mould inhibitor, buffer reagent etc.

Along with the development of automotive industry, performance requriements to engine is also more and more higher, not only require deicing fluid to there is lower freezing point and higher boiling point, also should there is good anti-corrosion of metal, cavitation-preventive, good antiscale property, and environmental pollution is little or free from environmental pollution, and there is the over-all properties of aspect in longer work-ing life etc.A large amount of research has all been done by various countries to this, constantly release formula patent and good deicing fluid commodity.The deicing fluid popularity rate of some advanced countries has reached 100%.The popularity rate of domestic deicing fluid is lower, and it is import that commercially available deicing fluid has a great deal of, because price is higher, is generally used for imported vehicle.Although domestic deicing fluid production increase is very fast in recent years, many products are owing to lacking strict quality test and unified inspecting standard, second-rate.For this reason, must absorb external modern technique the reality in conjunction with China, the multi-functional high efficient antifreeze liquid of Development and Production meets the growing market requirement.

Summary of the invention

The object of the present invention is to provide a kind of automobile engine winterization fluid, this deicing fluid is made up of alcohol, sodium, saline solution, and proportioning is simple, with low cost, preservative property are good low temperature resistant.

The object of the invention is to be achieved through the following technical solutions:

A kind of automobile engine winterization fluid, described deicing fluid is made up of the feed composition of following weight part:

Propylene glycol: 0 ~ 20 part; Ethylene glycol: 0 ~ 20 part; Butyleneglycol: 0 ~ 20 part; Sodium phosphate: 0 ~ 1 part; Water glass: 0 ~ 1 part; Hydrochloride: 0 ~ 30.0 part; Borax: 0 ~ 12 part; Petroleum resin: 0 ~ 18 part; Glycine: 0 ~ 10 part; Phenylpropyl alcohol triazole: 0 ~ 10 part; Defoamer: 0 ~ 1.0 part; Water: 0 ~ 60 part; Wherein buffer reagent is sodium phosphate, water glass and borax; Defoamer is dimethyl silicone oil or tributyl phosphate; Frostproofer is dibasic alcohol; Inhibiter is phenylpropyl alcohol triazole; Hydrochloride is one or more in basic metal, alkaline-earth metal and the 3rd main group element hydrochloride; Mould inhibitor is glycine, petroleum resin.

Embodiment

Below in conjunction with embodiment, the invention will be further described.
