Description
Technical field
The present invention relates to a kind of anhydrous 1,2-PD anti-freeze cooling liquid that automobile cooling system is protected in all directions, particularly a kind of anhydrous 1,2-PD organic acid anti-freeze cooling liquid.
Background technology
Anti-freeze cooling liquid is a kind of liquid of low freezing point, the aqueous solution that contains at low temperatures certain dibasic alcohol can not freeze, there is good mobility, can take away the amount of heat that engine produces in operation process, can be throughout the year for cooling systems such as automobile, boats and ships, large cooling columns, have anti-ly boil, the advantage such as anticorrosion, good antiscale property, antifreeze, vaporization prevention loss.
The kind of anti-freeze cooling liquid is according to can be divided into environment amenable organic acid type anti-freeze cooling liquid and low-grade inorganic salt type anti-freeze cooling liquid to the evaluation of environmental influence, low-grade inorganic salt type anti-freeze cooling liquid is in the international market by eliminating gradually, easily produce fouling, separate out precipitation, environmental pollution is serious.Organic acid type anti-freeze cooling liquid, more friendly to environment, in use procedure, can extend the work-ing life of anti-freeze cooling liquid, obtained gradually people's approval, but for general organic acid type anti-freeze cooling liquid, be all to have used ethylene glycol as frostproofer in production, ethylene glycol is poisonous, and readily biodegradable not, this has limited the widespread use of ethylene glycol type organic acid formula technique undoubtedly.In recent years along with development and the attention of people to environment protection of Domestic Automotive Industry; 1; 2-propylene glycol due to its have be similar to ethylene glycol can be as nearly all characteristic of frostproofer; but nontoxic; can realize natural biological degradation; therefore 1,2-PD type anti-freeze cooling liquid is taken seriously gradually.
And for research 1,2-propylene glycol anti-freeze cooling liquid, study its application and be not only confined to directly use type anti-freeze cooling liquid, directly use type propylene glycol anti-freeze cooling liquid has natural environment-friendly advantage than ethylene glycol type anti-freeze cooling liquid, but still can easily occur galvanic corrosion because of the existence of water, and equally with ethylene glycol antifreeze need under pressurized state, realize the raising of cooling fluid working temperature.
Summary of the invention
Technical problem to be solved by this invention is: the anhydrous 1,2-PD anti-freeze cooling liquid that a kind of long-acting, environmental protection, resistance to metallic corrosion is provided and can dissolves each other with additive.
In order to address the above problem, technical scheme of the present invention is: a kind of 1,2-PD anti-freeze cooling liquid, by mass percentage, comprises following component:
Sebacic acid: 0.5～3.0%;
Succinic acid: 0.25～1.5%;
Benzotriazole: 0.1～0.9%;
Hydrolytic polymaleic anhydride: 0.05～0.3%;
Defoamer: 0.0004～0.005%;
1,2-PD: surplus.
Described sebacic acid and succinic acid mass ratio are 2:1.
Described 1,2-PD anti-freeze cooling liquid, the preferred proportion of said components is:
Sebacic acid: 1～1.8%;
Succinic acid: 0.5～0.9%;
Benzotriazole: 0.15～0.3%;
Hydrolytic polymaleic anhydride: 0.1～0.14%;
Defoamer: 0.00045%;
1,2-PD: surplus.
The invention has the beneficial effects as follows: 1,2-PD anti-freeze cooling liquid compound formula system disclosed by the invention is all organic acid, the sebacic acid of widely applying in formula and succinic acid have played good addition by collaborative protection to the solidity to corrosion of metal; When sebacic acid and succinic acid mass ratio are 2:1, the solidity to corrosion best results to metal, detects data from embodiment and can find out.
Simultaneously, of the present invention anhydrous 1,2-propylene glycol organic acid anti-freeze cooling liquid formula technique has anhydrous corrosion-resistant, low temperature performance excellent, nontoxic, environment more, can under the condition that does not need pressurization, realize the lifting of the temperature of anti-freeze cooling liquid, in heavy-duty engine, application almost can be eliminated the technical barriers such as lining spot corrosion, aluminium pump cavitation corrosion completely, can extensively use automobile, boats and ships, large cooling column, sun power etc. as the heat-conducting medium of cooling system.
Embodiment
Below by concrete enforcement, the present invention is described in further detail.
For ease of distinguishing the deicing fluid of different freezing points and different varieties, technical scheme disclosed by the invention can also add dyestuff, and dyestuff content is 0.001～0.008% by mass percentage, in this mass range, to the performance of this antifreeze system, can not exert an influence; Color is one or more mixing in green system, yellow system, red colour system, blue series.
