Abstract
The invention discloses a phosphorus-free multi-effective antifreeze solution, comprising the following components by mass percent: 35-90% of ethylene glycol, 0.05-1% of sodium molybdate, 0.4-2.5% of sodium nitrate, 0.3-0.9% of benzotriazole, 0.5-3.6% of sebacic acid, 0.25-3% of undecanedioic acid, 0.05-0.5% of hydrolyzed polymaleic anhydride, 0.001-0.005% of antifoaming agent and the balance deionized water. The invention has the advantages that a phosphate radical free formula system is adopted; in the formula, the sodium molybdate and the organic acid cooperate to protect the metal, and the sodium nitrate is used to assist to provide durable metal corrosion for a long-term; and a great amount of sebacic acid is used in the formula so as to take good addition effect on the corrosion of the metal.
Description
Technical field
The present invention relates to a kind of deicing fluid system that automobile cooling system is carried out multilayer protection in all directions, relate in particular to a kind of phosphorus-free multi-effective antifreeze solution.
Background technology
Deicing fluid is a kind of liquid of low freezing point, the aqueous solution that contains certain ethylene glycol amount at low temperatures can not freeze, has good flowability, can take away a large amount of heats that engine produces in operation process, can be used for the automobile antifreeze solution water cooling system throughout the year, play anti-boil, advantages such as anticorrosion, good antiscale property, antifreeze, vaporization prevention loss.
The kind of deicing fluid can be divided into environment amenable pure organic acid type deicing fluid and low-grade inorganic salt type deicing fluid according to the evaluation to environmental influence, pure organic acid type deicing fluid is environmentally friendly, biological degradation easily, but use cost is comparatively expensive, therefore can not get larger area in China always and promotes.In recent years along with the development of Domestic Automotive Industry, the deicing fluid system also integrates with to pure organic acid prescription gradually, the composite organic acid type formula technique that a large amount of phosphorated add the part inorganic salt has appearred in market, but for market, especially American-European market, a kind of use that is under an embargo of phosphorous deicing fluid, phosphorus causes the oxygen enrichmentization of water of river and lake easily, so lower-cost without phosphorus organic acid deicing fluid has just had a large amount of demands.And for without phosphorus deicing fluid, its anti-metallic corrosion just need be done number of research projects, not only will solve it and prevent the metallic corrosion problem, also will solve the endurance issues of its use.
Summary of the invention
Technical problem to be solved by this invention is: a kind of phosphorus-free multi-effective antifreeze solution that does not contain phosphate anion and do not use the inorganic salts of low-grade silicon, boron is provided.Solved anti-metallic corrosion problem, more long lasting protective effect can be provided.
In order to address the above problem, technical scheme of the present invention is: phosphorus-free multi-effective antifreeze solution by mass percentage, comprises following component:
Ethylene glycol: 35～90%,
Sodium orthomolybdate: 0.05～1%,
SODIUMNITRATE: 0.4～2.5%,

11 carbon dicarboxylic acids: 0.25～3%,
Hydrolytic polymaleic anhydride: 0.05～0.5%,
Defoamer: 0.001～0.005%,
Deionized water: all the other.
In order to address the above problem better, further technical scheme of the present invention is: also contain dyestuff at described phosphorus-free multi-effective antifreeze solution, by mass percentage: dyestuff content is 0.001～0.008%, and color is one or more mixing in green system, yellow system, red colour system, the blue system.
In order to address the above problem better, further technical scheme of the present invention is: by mass percentage, comprise following component:
Ethylene glycol: 90%,
Sodium orthomolybdate: 0.4%,
SODIUMNITRATE: 0.72%,
The phenylpropyl alcohol triazole: 0.5%,
The certain herbaceous plants with big flowers diacid: 2.5%,
