Abstract
The invention discloses a pitting-prevention engine liquid coolant. The pitting-prevention engine liquid coolant is prepared from a propylene glycol-ethylene glycol mixture, citric acid, dimethicone, tricarboxylic acid, nanometer alumina, guar gum, pentaerythritol and glycerin. The pitting-prevention engine liquid coolant has good cooling effects. Through tricarboxylic acid-triethanolamine-nanometer alumina-guar gum mixing pretreatment, liquid coolant structure properties are improved, engine coolant-caused engine cooling system pitting is greatly reduced and pitting corrosion inhibition protection performances are improved. The pitting-prevention engine liquid coolant has good antifreezing effects and no corrosivity and does not pollute a cooling pipe.
Description
Technical field
The present invention relates to cooling fluid technical field, particularly relate to a kind of anti-spot corrosion 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 engine coolant can not get solving to engine-cooling system pitting problem always, many tentative solution effects are not good, the effect of the cooling fluid control spot corrosion of single utilization ternary poly carboxylic acid does not reach desirable, can not meet the demand of many occasions.
Summary of the invention
The object of this invention is to provide a kind of anti-spot corrosion engine coolant.
The present invention is achieved through the following technical solutions:
A kind of anti-spot corrosion engine coolant, be made up of following composition by weight, propylene glycol and ethylene glycol blend 145 parts, citric acid 6 parts, dimethyl silicone oil 12 parts, ternary poly carboxylic acid 15 parts, nano aluminium oxide 8 parts, guar gum 14 parts, tetramethylolmethane 8 parts, glycerine 12 parts.
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, the granularity of described nano aluminium oxide is 10-12nm.
Further, ternary poly carboxylic acid is through pre-treatment: mixed at 25-30 DEG C with trolamine by ternary poly carboxylic acid, continues after 30 minutes, adds nano aluminium oxide and guar gum, uniform stirring 10 minutes.
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 1:1 ratio with octamethylcyclotetrasiloxane.
The invention has the beneficial effects as follows, compared with prior art:
Cooling fluid of the present invention; cooling is good; what to coordinate nano aluminium oxide and guar gum with trolamine by ternary poly carboxylic acid mixes pre-treatment; improve the structure property of cooling fluid; greatly reduce the spot corrosion of engine coolant to engine-cooling system, improve the suppression protective value to cavitation corrosion, and the antifreeze effect of cooling fluid of the present invention is good; cooling fluid non-corrosiveness, can not pollute cooling line.
