Embodiment 1

[0035] The present invention proposes an ultra-low temperature nano-antifreeze isolation emulsion, which still has high stability and excellent anti-corrosion performance at ultra-low temperatures, so as to effectively solve the problem of frozen trains.

[0036] Specifically, the ultra-low temperature nano antifreeze isolation emulsion includes 100 parts by weight of mineral oil and / or bio-oil, 0.1-1 part by weight of auxiliary agent A, 1-2 parts by weight of auxiliary agent B and 13-50 parts by weight of water.

[0037] The auxiliary agent A includes ethylene / vinyl acetate copolymer, acrylate polymer, maleic anhydride copolymer, polyoxyethylene alkylamine or a mixture of any two or more of the above. The auxiliary agent B includes sorbitol fatty acid ester, polyglycerol fatty acid ester, polyoxyethylene fatty acid ester, isostearic acid monoglyceride, monoalkenyl succinimide, polyalkenyl succinimide Or a mixture of any two or more of the above types. The auxiliary agent A i...

Embodiment 2

[0050] Another object of the present invention is to provide a method for preparing an ultra-low temperature nano antifreeze isolation emulsion, said preparation method comprising the following steps:

[0051] 1) Add 0.1-1 parts by weight of auxiliary agent A and 1-2 parts by weight of auxiliary agent B to 100 parts by weight of mineral oil and / or bio-oil, and stir evenly, wherein the auxiliary agent A includes ethylene / vinyl acetate copolymerization acrylate polymer, maleic anhydride copolymer, polyoxyethylene alkylamine or a mixture of any two or more of the above, the auxiliary agent B includes sorbitol fatty acid ester, polyglycerin fatty acid ester, poly Oxyethylene fatty acid ester, monoglyceride isostearate, monoalkenyl succinimide, polyalkenyl succinimide or a mixture of any two or more of the above;

[0052] 2) Increase the rotating speed and stir, and add 13 to 50 parts by weight of water;

[0053] 3) After stirring for 20 min, the mixture turns white or light yello...

Embodiment 3

[0059] The difference between this example and Example 2 is that in this example, 35kg of mineral oil is added to the reaction vessel, 0.15kg of acrylate polymer and 0.4kg of polyglycerol fatty acid ester are added respectively, the speed is set at 500r / min, and the mixture is stirred evenly . Then increase the rotation speed to above 3000r / min, then add 10kg of water, and stir for 20 minutes, and the system turns white or light yellow, and the ultra-low temperature nano antifreeze isolation emulsion is obtained.

[0060] The main technical indicators of the ultra-low temperature nano antifreeze isolation emulsion prepared by the above preparation method are: viscosity 13.7mPa·s, pour point -43°C, good performance at ultra-low temperature.

Abstract

The invention relates to an ultralow temperature nano antifreezing isolating emulsion, and a preparation method thereof. The ultralow temperature nano antifreezing isolating emulsion comprises, by weight, 100 parts of a mineral oil and / or a biological oil, 0.1 to 1 part of an accessory ingredient A, 1 to 2 parts of an accessory ingredient B, and 13 to 50 parts of water; the accessory ingredient A comprises ethylene / vinyl acetate copolymer, an acrylate polymer, a maleic anhydride copolymer, polyoxyethylene alkyl amine, or a mixture of three or more ingredients selected from the above; and the accessory ingredient B comprises a sorbitol fatty acid ester, a polyglycerol fatty acid ester, a polyoxyethylene fatty acid ester, an isostearic acid monoglyceride, a monoolefine succinimide, a polyene succinimide, or a mixture of three or more ingredients selected from the above. The ultralow temperature nano antifreezing isolating emulsion is an oil substance, is low in pour point and corrosivity, is hydrophobic, and is capable of avoiding freezing of coal conveyors effectively.

Description

technical field [0001] The invention relates to an antifreeze isolation emulsion, in particular to an ultra-low temperature nanometer antifreeze isolation emulsion and a preparation method thereof. Background technique [0002] Coal is one of the main energy sources in my country, but the distribution of coal resources and economic development are extremely unbalanced, with more in the north than in the south, more in the west and less in the east. In order to reduce the sulfur content and ash content of coal, most of the coal has undergone a coal washing process before transportation, and the water content of the washed coal is generally about 8-13%. In winter in the north, coal with high water content will freeze during loading and transportation, especially with the coal carriage, which will affect the unloading speed and cause phenomena such as crushing the car and port. If the unloading of the frozen car is not clean, it will also cause the empty car to be heavy, serio...
