preparation example Construction

[0016] The antirust oil provided by the invention has a simple preparation method, and can be prepared by uniformly mixing all components. The specific preparation method is: heat castor oil to 120-180°C, add lanolin magnesium soap and stir for 1-2 hours, cool to 75-85°C, add barium petroleum sulfonate or calcium petroleum sulfonate, dinonyl Barium naphthalenesulfonate, N-oleoyl sarcosine octadecylamine, dodecenyl succinic acid, zinc naphthenate, stirred for 1-3 hours, then cooled to 40-50°C and filtered to obtain the present invention Anti-rust oil provided.

[0017] When the anti-rust oil provided by the invention also contains anti-rust peelable film and / or simethicone, the specific preparation method is: heat up castor oil to 120-180°C, then add lanolin magnesium soap and stir for 1- After cooling to 75-85°C for 2 hours, add barium petroleum sulfonate or calcium petroleum sulfonate, barium dinonylnaphthalenesulfonate, N-oleoyl sarcosine octadecylamine, dodecenylsuccinic a...

Embodiment 1

[0026] This embodiment is used to illustrate the antirust oil provided by the present invention.

[0027] Add 75 parts by weight of castor oil in the reactor, add 10 parts by weight of magnesium lanolin soap after being warmed up to 160 ° C, and stir at this temperature for 1.5 hours, add 14 parts by weight of barium petroleum sulfonate and 1 parts by weight of zinc naphthenate, and stirred at this temperature for 2 hours, then cooled to 45° C. and filtered through a 60-mesh stainless steel wire filter, and the resulting 99.5 parts by weight of filtrate was the antirust oil to be obtained.

Embodiment 2

[0029] This embodiment is used to illustrate the antirust oil provided by the present invention.

[0030] Add 62.7 parts by weight of castor oil to the reactor, add 12 parts by weight of magnesium lanolin soap after heating up to 120°C, and stir at this temperature for 2 hours, add 17 parts by weight of barium petroleum sulfonate after natural cooling to 75°C, 8 parts by weight of barium dinonylnaphthalene sulfonate, 0.1 part by weight of N-oleoyl sarcosine stearylamine, 0.1 part by weight of dodecenylsuccinic acid and 0.1 part by weight of zinc naphthenate, and stirred at this temperature After 3 hours, it was cooled to 40° C. and filtered through a 60-mesh stainless steel wire filter, and the obtained 99.3 parts by weight of the filtrate was the antirust oil to be obtained.

Abstract

The invention provides anti-rust oil, which contains base oil and an anti-rusting agent, wherein the base oil is castor oil; and based on the total weight of the anti-rust oil, the castor oil content is 60 to 84 percent, and the anti-rusting agent content is 16 to 40 percent. The invention also provides a method for producing the rustproof steel rail, and the method comprises of uniformly coatingthe anti-rust oil provided by the method on the substrate surface of the steel rail. Because of the use of the anti-rust oil provided by the invention, the rustproof steel rail produced by using the anti-rust oil has excellent short-period rustproof effect, and the anti-rust oil provided by the invention has quite good preparation and use performances.

Description

technical field [0001] The invention relates to an antirust oil and a method for producing antirust steel rails with the antirust oil. Background technique [0002] After the steel rails for railways are produced by iron and steel enterprises, they need to be transported by rail (or by sea) to reach the user. The user also needs to weld them into 250m~500m long rails and stack them, and then transport them to the railway line with a long rail car for track laying. It will take some time until the railway is officially put into operation. Generally, the cycle from the delivery of the rails to the official operation after laying the rails is generally within one year. Under normal circumstances, during the transportation process of ordinary steel rails after leaving the factory, especially in ocean shipping under marine environmental conditions, due to the sun and rain under natural conditions, the surface of ordinary rails has begun to rust and turn yellow after reaching rail...
