Abstract
The present invention relates to compound cooling fluid for engines and a preparing process thereof. Deionized water, ethylene glycol, triethanolamine, benzotriazole, phosphoric acid, borax, sodium benzoate, sodium hydroxide, a corrosion inhibitor, a defoaming agent and a coloring agent form raw materials and are mixed for reaction under certain conditions. Then, the cooling fluid is formed by filtration and package. The product is applied to cooling systems of various imported and domestic engines and can be suitable for climatic conditions of different areas. The present invention has the advantages of favorable freezing prevention, cleaning performance, dirt prevention, long term corrosion resistance, oxidation resistance, foaming resistance, high boiling point, stable and reliable quality, favorable performance, favorable use effect, etc.
Description
Technical field
The present invention relates to a kind of fine chemical product, particularly a kind of automobile and the compound cooling fluid of light duty engine.
Background technology
Cooling system is the automobile-used important component part that waits engine, and its effect is that the parts that high temperature is worked are down given suitable cooling, to guarantee that engine can works better under optimal temperature.The antifreeze cooling performance of cooling fluid, antiscale and performance such as anticorrosive are the keys that guarantees the normal operation of cooling system.Though cars on hand is with on the engine coolant market, related products is of a great variety, but defectives such as existing short, easily fouling or the easy oxidation of burn in work-ing life mostly, easily bubble, boiling point is low, cause reduction of cooling system heat transfer efficiency or cooling system impaired, also cause cooling fluid rotten or volatile in addition.The replacing frequency that this has not only increased cooling fluid causes waste economically, and has had a strong impact on the works better of engine, has shortened engine operation life.
Summary of the invention
The objective of the invention is to by the rational automobile of a kind of prescription and the compound cooling fluid of light duty engine and preparation method thereof are provided, make cooling fluid under condition of different temperatures, have good antifreeze, cleaning scale inhibition, anticorrosive, anti-oxidant, the anti-foaming and performances such as boiling point height lastingly, to reach good cooling results, prolong the cooling fluid life cycle, guarantee the normal operation of cooling system and prolong the engine purpose in work-ing life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of composite engine coolant is provided, this compound cooling fluid is made up of deionized water, ethylene glycol, trolamine, benzotriazole, phosphoric acid, borax, Sodium Benzoate, sodium hydroxide, inhibiter, defoamer and staining agent, and the weight percentage of each component is:
Deionized water 30.00-68.00
Ethylene glycol 30.00-68.00

Wherein, owing to do not contain the ion of easy fouling, reduced the chance of compound cooling fluid fouling in the deionized water; Even sneak into a spot of scale-forming ion, can also form water-soluble substances and reach the purpose that prevents fouling with Scale inhibitors phosphoric acid, borax, the sodium hydroxide complexing in the compound cooling fluid; One group of good persistent inhibiter benzotriazole, inhibiter can form protective membrane in metallic surfaces such as the copper of forming engine, steel, scolder, cast iron, cast aluminiums in the compound cooling fluid, stop the oxidized and corrosion of these metals.The preparation method of this composite engine coolant is: compound cooling fluid is by being made up of deionized water, ethylene glycol, trolamine, benzotriazole, phosphoric acid, borax, Sodium Benzoate, sodium hydroxide, inhibiter, defoamer and staining agent, and the weight percentage of each component is:
Deionized water 30.00-68.00
Ethylene glycol 30.00-68.00
Trolamine 0.10-0.80
Benzotriazole 0.05-0.12
Phosphoric acid 0.30-1.10
Borax 0.07-0.14
Sodium Benzoate 0.40-1.50
Sodium hydroxide 0.10-0.80
Inhibiter is an amount of
Defoamer is an amount of
Staining agent is an amount of
Concrete preparation method is: the deionized water that at first adds formula ratio in blending kettle, extract the ethylene glycol of formula ratio in the raw material storage tank in blending kettle with the feed cycle pump again, open simultaneously and stir and the revolution circulation process, then in still, add trolamine, benzotriazole, phosphoric acid, borax, Sodium Benzoate, sodium hydroxide, inhibiter, defoamer and staining agent successively by formula ratio, circulate under 25 ℃ of-60 ℃ of temperature, mixed 4-10 hour, product is packed after pressure filter filters and is finished product.
Composite engine coolant provided by the present invention can be divided into-No. 25 by freezing point--and-No. 50 a plurality of models can adapt under the weather condition of different areas the cooling system of various imports and homemade engine.Not only have performances such as good antifreeze cooling, scale inhibition cleaning; And have anti-oxidant lastingly, a corrosion resistance, product boiling point height, anti-ly bubble, vaporization losses is few, long service life.Product uses confirmation through evaluation in continuous 3 years of authoritative quality surveillance mechanism and the driving in 4 years of user, constant product quality, reliable, and superior performance, respond well.
The invention will be further described below in conjunction with embodiment.
