[0035] ⑥Antioxidant is 0.1 part of 2,6-di-tert-butyl-p-cresol.

[0036] Production process: first add the base oil to the reactor, heat and stir, then add the rust inhibitor at 100-140°C, then add the film forming agent, tackifier and antioxidant, co...

Embodiment 2

[0038] The difference from Example 1 is:

[0039] Concrete material and parts by weight of each component selected in the present embodiment are as follows:

[0040] 1. base oil is isoparaffin, and its weight portion is 50 parts (in the present embodiment, the concrete molecular formula of isoparaffin is C n h 2n+2 , n=10);

[0041] 2. The antirust agent is barium petroleum sulfonate and neutral barium dinonylnaphthalene sulfonate, and the parts by weight are 17 parts and 6 parts respectively;

[0042] 3. film-forming agent is asphalt, p-tert-butylphenol formaldehyde resin, and parts by weight are respectively 2 parts, 15 parts;

[0043] 4. Tackifier is vaseline, and polyisobutylene is 1 part, 4 parts by weight respectively;

[0044] ⑤ 1 part of Benzene-80;

[0045] ⑥Antioxidant is 0.1 part of 2,6-di-tert-butyl-p-cresol.

[0046] In this example, the anti-rust oil has a flash point of 54°C and a viscosity of 36mm at 40°C. 2 / s.

Embodiment 3

[0048] The difference from Example 1 is:

[0049] Concrete material and parts by weight of each component selected in the present embodiment are as follows:

[0050] 1. base oil is isoparaffin, and its weight portion is 52.4 parts (in the present embodiment, the concrete molecular formula of isoparaffin is C n h 2n+2 , n=10);

[0051] 2. The antirust agent is barium petroleum sulfonate and neutral barium dinonylnaphthalene sulfonate, and the parts by weight are 14 parts and 6 parts respectively;

[0052] 3. film-forming agent is asphalt, p-tert-butylphenol formaldehyde resin, and parts by weight are respectively 2 parts, 15 parts;

[0053] 4. tackifier is Vaseline, polyisobutylene weight parts are respectively 3 parts, 5 parts;

[0054] ⑤ 2 parts of benzene-80;

[0055] ⑥ The antioxidant is 0.6 parts of 2,6-di-tert-butyl-p-cresol.

[0056] In this example, the flash point of the anti-rust oil is 54°C, and the viscosity at 40°C is 34mm 2 / s.

Abstract

The invention relates to the field of metal rust prevention, in particular to antirust oil for a high-speed railway track switch, which is environmental friendly and has the function of removing rust and a production method thereof. The antirust oil comprises the following components in parts by weight: 40-60 parts of base oil, 5-25 parts of antirust agent, 1-20 parts of film former, 1-5 parts of span-80, 1-10 parts of tackifier and 0.1-2 parts of antioxidant. The method comprises the following steps of: firstly, adding base oil into a reaction kettle to heat and stir until the temperature reaches 100-140 DEG C and adding an antirust agent; adding a film former, a tackifier and an antioxidant, continuously stirring and cooling to 30-50 DEG C and then adding span-80 and the balance of base oil, continuously stirring for 1-3 h and filtering to obtain a finished product. The viscosity of an oil product is controlled to be 20-50 mm<2>/s at 40 DEG C through screening out the composite ratio of the base oil and various additives for many times, thereby ensuring the favorable permeability and drying within 1-2 h, the metal is maintained to be stored out-of-doors, weathers wind and rain, and has favorable antirust property in the severe sun-baked environment. Furthermore, the oil product belongs to hard coat antirust oil and is stored out-of-doors after dried, reduces the adhesion of dust, and ensures the attractive appearance of the product.

Description

Technical field: [0001] The invention relates to the field of metal antirust, in particular to an environment-friendly high-speed rail turnout antirust oil with derusting function and a production method. Background technique: [0002] The basic requirement for metal antirust is to pretreat the antirust object to achieve the close adhesion of the antirust agent on the metal surface, form a firm film, and cut off corrosive substances such as water and oxygen. However, many enterprises are affected by objective conditions such as production environment and production tasks, and cannot completely remove the rust that has formed on the metal surface. Therefore, be badly in need of a kind of medium and short-term anti-rust oil that can be applied to lightly corroded metals by removing surface dust and floating rust on the market. This technology and product have a wide range of practical application value for large quantities of steel and steel accessories stored in the open air...
