Abstract
The invention discloses a kind of propylene glycol anhydrous cooling liquid, is made of following raw materials by mass parts：1,2 100 parts of propane diols, 0.1 0.5 parts of methylbenzotriazole, 0.5 1.5 parts of polyaminoacid, 0.1 0.5 parts of diethylene triamine pentacetic acid (DTPA) ferrisodium complex compound, 0.5 1.5 parts of sodium benzoate, 0.1 0.3 parts of dimethicone.The propylene glycol anhydrous cooling liquid of the present invention, stability is high, overcomes technological deficiency of the tradition containing easy " boiling " existing for water coolant, is conducive to engine and is run under fully loaded, high load capacity.
Description
Technical field
The present invention relates to a kind of coolant, more particularly to a kind of propylene glycol anhydrous cooling liquid.
Background technology
The full name of anti-icing fluid should be anti-freeze cooling liquid, mean the coolant of antifreeze function.Anti-icing fluid can prevent
Cold winter stop when unfrozen cooling fluid and spalling radiator and freezing engine cylinder block or lid.But we will correct one
Misread, anti-icing fluid is not only winter, it should be used in whole year.Automobile normally in maintenance project, often travels 1 year,
Need to change engine fluid.
Coolant is mainly used in car engine cooling system, and there is cooling, antifreeze, antiscale, anti-corrosion, anti-boiling etc. to make
With.Coolant is mainly made of antifreezing agent, water, corrosion inhibiter, defoamer, coloring agent etc..The key technology of coolant is various slow
Lose the reasonable interworking of the additive such as agent and defoamer.The comprehensive performance for having cooled down liquid product is still not ideal enough.
Tradition contains water coolant, there is the technological deficiency of easy " boiling ".
The content of the invention
The first technical problem to be solved by the present invention is to provide a kind of propylene glycol anhydrous cooling liquid.
The present invention, is achieved by the following technical solution：
A kind of propylene glycol anhydrous cooling liquid, is made of following raw materials by mass parts：1,2- propane diols (No. CAS：57-55-
6) 100 parts, methylbenzotriazole (No. CAS：29385-43-1) 0.1-0.5 parts, 0.5-1.5 parts of polyaminoacid, divinyl three
Triamine pentaacetic acid iron-sodium complex (No. CAS：12389-75-2) 0.1-0.5 parts, sodium benzoate (No. CAS：532-32-1)0.5-
1.5 parts, dimethicone (No. CAS：9006-65-9) 0.1-0.3 parts.
The polyaminoacid is poly-aspartic-acid (No. CAS：181828-06-8), poly- L-Leu (No. CAS：
25322-63-8) and polyglycine (No. CAS：One kind or its mixture in 25718-94-9).
Preferably, the polyaminoacid is poly-aspartic-acid and the mixture of poly- L-Leu, wherein poly-aspartic
The mass ratio of sour and poly- L-Leu is 4:1-1:4.
Above-mentioned raw materials are mixed, are stirred evenly, all materials mix the propylene glycol anhydrous type cooling that can be prepared by the present invention
Liquid.Into one step of addition, can again with sodium hydroxide or potassium hydroxide adjust the propylene glycol anhydrous cooling liquid pH of the present invention to
8-9。
The propylene glycol anhydrous cooling liquid of the present invention, stability is high, does not block pipeline, and antifreeze, antirust, scaling property
Height, can effectively prevent the corrosion to ferrous metal, tin, copper and copper alloy, aluminium and aluminium alloy, and overcome tradition to contain water coolant
The technological deficiency of existing easily " boiling ", is conducive to engine and is run under fully loaded, high load capacity, can ensure that vehicle in plateau, sand
The adverse circumstances such as desert, cold drive safely, and are particularly suitable for military vehicle, high-end vehicles and high-power heavy load lorry and visitor
Car.
Embodiment
With reference to embodiment, the invention will be further described.
Embodiment 1-4
At room temperature, correspond to embodiment 1-4 by table 1 and weigh each raw material, each raw material is mixed, is stirred evenly, be hydrogenated with sodium oxide molybdena
