Abstract
The present invention relates to an LNG vehicle anti-freezing liquid, and provides a new special LNG vehicle anti-freezing liquid used for cold regions and having characteristics of excellent corrosion resistance, rust resistance, scale inhibition, high boiling point, and low freezing point. The LNG vehicle anti-freezing liquid is characterized by comprising, by weight, 35-55% of ethylene glycol, 5-30% of dimethyl sulfoxide, 0.1-0.3% of sodium molybdate, 0.1-0.4% of potassium dihydrogen phosphate, 0.1-0.6% of benzotriazole, 0.1-0.3% of phthalic acid, 0.1-0.3% of Isophthalic acid, 0.05-0.8% of mercapto benzothiazole, 0.1-0.3% of sodium nitrate, 0.05-0.2% of sodium benzoate, 0.1-0.5% of sodium hydroxide, 0.0005-0.0015% of fluorescein, and the balance of deionized water.
Description
Technical field
The present invention relates to a kind of deicing fluid, particularly a kind of deicing fluid on LNG automobile.
Background technology
Vehicular liquefied Sweet natural gas stores with the liquid state of low temperature and gaseous form in gas cylinder, and can be drawn out of from gas cylinder with pure liquid form or gas-liquid mixed form, being heated by liquified natural gas vaporizer and pipeline thereof becomes gaseous phase.Vaporizer is arranged between gas cylinder and engine.Vaporizer is connected with engine-cooling system, and cooling fluid (engine provides) flows through vaporizer shell side and heats to tube side.When natural gas liquids enters vaporizer, the high temperature coolant from engine is gasified and is heated, subsequently supply engine.
Automobile-used LNG liquefying-point is-161.5 DEG C, absorbs deicing fluid large calorimetric, cause deicing fluid freezed in winter in vaporizer when vaporizer gasifies, and deicing fluid can not proper flow, affects the normal use of automobile.Therefore, traditional deicing fluid resistance to frost does not reach the service requirements that LNG is heavily stuck in cold district in winter.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of deicing fluid of cold district LNG automobile specified with excellent anticorrosion, antirust, antiscale, high boiling point, low freezing point newly.
In order to solve the problem, this kind of LNG automobile antifreeze solution, it is characterized in that being made up of following substances in percentage by weight:
The invention has the beneficial effects as follows: LNG automobile engine winterization fluid of the present invention.The basis of traditional ethylene glycol type deicing fluid is added the second frostproofer dimethyl sulfoxide (DMSO), significantly lowers the freezing point of deicing fluid, good freezing protection effect, freeze point depression amplitude is large, and minimum freezing point is low to moderate-65 DEG C of low temperature uses and does not freeze.Suppress corrosive effect good, very micro-to aluminium, steel and iron corrosion.Additive benzotriazole can improve deicing fluid and intermetallic heat conduction velocity, and can slow down the precipitation of rust deposite.
