Abstract
There is provided an anti-freezing liquid comprised of inorganic salt calcium chloride as main component with additive soluble glycerine, water and small amount of methylene blue, it surmounts the short-coming of prior art technology for antifreezing liquid prepared from organic dibasic alcohol, its pH value is 6.5, cost is low, except ice-point and boiling point, the other specifications reach or approach to that of American SAE-J814 anti-freezing liquid.
Description
The present invention relates to the freezing proof technique field of motor car engine, relate to a kind of automobile, tractor engine antifreezing circulation liquid and compound method thereof specifically.
Winter temperature is low, and the water tank of automobile is often frozen at night, influences its normal starting, can solve the problem that automobile water tank froze at night and add the lower deicing fluid of freezing point.At present, component from known deicing fluid, countries in the world are main raw material with dibasic alcohol or its acid amides all, is main component as deicing fluid produced in USA with ethylene glycol, outer adding preservative agent, soluble oil or borax, benzotriazole, the phosphoric acid ester of trolamine, compositions such as SODIUMNITRATE, the deicing fluid that Japan produces also is main raw material with ethylene glycol, but owing to the spurt in prices of ethylene glycol uses 1 instead, the 2-propylene glycol is a main raw material, add a spot of sanitas, defoamer, loss circulation material is formed by combining, but it exists following shortcoming: (1) price height is equivalent to about 15 yuan/kilogram of Renminbi; (2) pH value of deicing fluid is big, and alkalescence is strong, and is big to the corrodibility of water tank; (3) in use lossy because of volatilizing gradually.
Purpose of the present invention produces thus, will provide a kind of exactly and give radical change from component, and price is lower, and pH value is less, to the water tank non-corrosiveness and there is not the evaporable antifreezing circulation liquid.
The present invention adopts following technical scheme to realize: adopting inorganic salt calcium chloride is main component, and in order to prevent that inorganic salt solution from suitably adding additive soluble oil glycerine and a spot of methylene blue dyestuff to corrosion of metal.
(the unit: gram) be: calcium chloride: glycerine: water: methylene blue=30～40 grams: 1～6 gram: 50～95 grams: 0.05 gram of the weight ratio of each component in the antifreezing circulation liquid of the present invention
The compound method of antifreezing circulation liquid of the present invention is: the Calcium Chloride Powder Anhydrous that takes by weighing capacity, weight ratio by component adds proper amount of deionized water, stirring makes it fully dissolve, filter, in filtrate, also add glycerine then and mix, add at last and promptly get described antifreezing circulation liquid after a spot of methylene dye mixes by the weight ratio of each component.
Antifreezing circulation liquid of the present invention, compared with the prior art, given the essence change from component, with inorganic salt calcium chloride is main ingredient, and having overcome with organic alcohol is that many shortcomings of the deicing fluid of main raw material preparation have its following characteristics: (1) its price is 1/4th of an import deicing fluid; (2) time limit of service can be permanently effective because of calcium chloride and little, the non-volatility of glycerin vapor pressure; (3) its pH value is 6.5, is one of the lowest in the present similar products at home and abroad, and is very favourable to reducing water tank corrodibility.The many after testing indexs of antifreezing circulation liquid of the present invention reach or are better than Japanese TCL non-freezing solution, and except that freezing point and boiling point, all the other technical indicators reach or substantially near U.S. SAE-J814 non-freezing solution index.
Calcium chloride Cacl in the antifreezing circulation liquid of the present invention
2, raw material may be the various crystallization hydrates of calcium chloride, Cacl because the source is different

2O because the water content difference, have dried have wet, but guarantee always to calculate its content by siccative, provide two embodiment below.
(1) takes by weighing Calcium Chloride Powder Anhydrous (Cacl
2) 35 grams, add deionized water 95 grams, stirring and dissolving, filtration, in filtrate, add 5 gram glycerine, mix, it is a small amount of to add methylene blue dyestuff again, promptly gets antifreezing circulation liquid after mixing.
(2) take by weighing Calcium Chloride Powder Anhydrous 35 gram, add deionized water 65 gram stirring and dissolving, filtration, in filtrate, add 2 gram glycerine and mix, add again methylene blue dyestuff a little, promptly get antifreezing circulation liquid after mixing.
Antifreezing circulation liquid of the present invention and Japanese TCL-PT and U.S. SAE-J814 are done the performance comparison experiment, and the result that national tractor mass supervision and inspection center is measured is shown in following antifreezing circulation liquid over-all properties contrast table.
Deicing fluid over-all properties contrast table
Being fit to temperate climate by visible embodiment 1 prescription of table uses winter; Embodiment 2 prescriptions are fit to climate of frigid zone to be used winter.
