Abstract
The invention discloses engine cooling liquid. The engine cooling liquid is prepared from a propylene glycol and ethanediol blend, potassium citrate, simethicone, sodium silicate, starch, pentaerythritol and pentaerythritol. The cooling liquid is good in cooling performance, the starch is pretreated and mixed with sodium silicate, the problems that due to gel polymerization of traditional silicate in cooling liquid, the corrosion inhibition performance of the cooling liquid is reduced, and a water channel is blocked are solved, and the problem that existing engine cooling liquid is in lack of protection on a cooling system cast aluminum component is further solved.
Description
Technical field
The present invention relates to cooling fluid technical field, particularly relate to a kind of engine coolant.
Background technology
Cooling fluid is a kind of complicated multicomponent system, and excellent cooling fluid should have heat radiation, protection against corrosion, antifreeze, the function such as high boiling point, scale-deposit-preventing and prevention foaming.Major part frostproofer is eliminated in succession due to a variety of causes, and as methyl alcohol, ethyl alcohol boiling point are low, vapor pressure is large and inflammable; Saline mixture easily gets rusty and produces crystalline deposit; Glycerine viscosity is higher, and freeze-proof is poor, incompatible with rubber; Diethylene Glycol low temperature viscosity is large, antirust ability difference etc., and China's available engine cooling fluid shortage is protected cooling system cast aluminium part.
Summary of the invention
The object of this invention is to provide a kind of engine coolant.
The present invention is achieved through the following technical solutions:
A kind of engine coolant, is made up of following composition, propylene glycol and ethylene glycol blend 160 parts, Tripotassium Citrate 3 parts, dimethyl silicone oil 8 parts, water glass 10 parts, starch 4 parts, tetramethylolmethane 8 parts, glycerine 12 parts by weight.
Further, described propylene glycol and ethylene glycol blend are after propylene glycol mixes in 1:3 ratio with ethylene glycol at 35-40 DEG C, and uniform stirring 30 minutes, stirring velocity is 300r/min.
Further, by described starch dispersion in deionized water, at 60-65 DEG C, be stirred to its complete gelatinization, in gained starch solution, add 80U/mL cellulase, solution pH value is adjusted to 5.5, temperature controls to 50 DEG C, reacts after 1.5 hours, starch solution pH value is adjusted to 9.0, keep temperature-resistant, add 100U/mL Sumizyme MP, react 3 hours, naturally cool to room temperature.
Further, described dimethyl silicone oil is through pre-treatment: be that the oligoethylene glycol methyl glycidyl ether of 1 part mixes with dimethyl silicone oil with the mixture of octamethylcyclotetrasiloxane by total weight parts, at temperature is 60 DEG C, and reaction 1-2 hour; Described polyoxyethylene glycol methyl glycidyl ether mixes in 1:3 ratio with octamethylcyclotetrasiloxane.
Further, by pretreated starch solution and water glass admixed together, at 45-50 DEG C, uniform stirring 30 minutes.
The invention has the beneficial effects as follows, compared with prior art:
Cooling fluid of the present invention; cooling is good; by the pre-treatment to starch; remix water glass; solve Conventional Portland and make the problems such as coolant inhibitor decline, blocking water channel due to the gel polymerisation problem of self in cooling fluid, also solve available engine cooling fluid and lack the problem that cooling system cast aluminium part is protected.
