Abstract
The invention aims to provide an antifreezing fluid, which comprises the following components by weight percentage: 40 to 90 percent of propylene glycol, 0.01 to 1 percent of anti-fouling corrosion inhibitor, 0.001 to 0.5 percent of antioxidant, and the balance of water. The antifreezing fluid has the advantages of high stability, difficult volatilization, no pipeline blockage, and high antifreezing, anti-rust, and anti-fouling performances.
Description
Technical field
The present invention relates to a kind of deicing fluid.
Background technology
Deicing fluid is widely used in automobile, tractor, mining machinery, freezing unit, to guarantee that equipment can normally move not by bursting by freezing under winter or low temperature.Deicing fluid main component commonly used at present all contains calcium chloride, methyl alcohol or ethylene glycol.Because methyl alcohol is volatile, boiling point is low, potential safety hazard is big, and calcium chloride then owing to easily precipitate, is clogged pipeline, and usage quantity descends gradually aborning.
Summary of the invention
The purpose of this invention is to provide a kind of deicing fluid.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of deicing fluid by weight percentage, comprises following component:
Propylene glycol 40～90%
Anti-incrustation corrosion inhibitor 0.01～1%
Antioxidant 0.001～0.5%
Water surplus.
Described propylene glycol is 1,2-propylene glycol or 1, a kind of in the ammediol.
Described anti-incrustation corrosion inhibitor is an organic phosphine class anti-incrustation corrosion inhibitor, is preferably a kind of in carboxyl ethylene phosphoric acid, amino trimethylene methyl acid phosphate or the benzotriazole.
Described antioxidant is a kind of in Resorcinol, p-ten.-butylcatechol or the MEHQ.
Described water is at least a in distilled water, ionized water or the pure water.
Beneficial effect of the present invention is: the stability height, and not volatile, not blocking pipe, and antifreeze, antirust, anti-fouling tendency height.
Embodiment
Embodiment 1:
Add 1 of 454kg in retort successively, the 2-propylene glycol adds the 540kg pure water, adds 5kg carboxyl ethylene phosphoric acid again, 1kg to the tert-butyl o diphenol, fully stirred through two hours and to get final product barrelling;
After testing, its fusing point reaches-22 ℃, satisfies the service requirements of freezing unit-20 ℃
Embodiment 2:
Add 1 of 610kg in retort successively, the 2-propylene glycol adds the 380kg deionized water, adds 8kg amino trimethylene methyl acid phosphate again, the MEHQ of 2kg, and fully stirring got final product barrelling through two hours;
Its fusing point reaches-40 ℃ after testing, satisfies-40 ℃ service requirements.
Embodiment 3:
Add 1 of 500kg in retort successively, ammediol adds 494kg distilled water, adds the 5kg benzotriazole again, the Resorcinol of 1kg, and fully stirring got final product barrelling through two hours;
After testing, its fusing point reaches-40 ℃, satisfies-40 ℃ service requirements.
