Abstract

The invention relates to antirust oil and a preparation method thereof. The antirust oil is prepared from the following components by weight percent: 20 to 35 percent of film forming agent, 5 to 15 percent of antirust agent, 0.1 to 5 percent of co-solvent, 0.1 to 2 percent of antioxidant and 40 to 75 percent of basic oil. The preparation method comprises the following steps: preparing all raw materials according to the components and the weight ratio, adding the basic oil into a reactor, heating and stirring, when the temperature is increased to 90 to 120 DEG C, adding the antirust agent, theco-solvent and the antioxidant, sufficiently stirring, completely dissolving, lowering the temperature in the reactor to 50 to 80 DEG C, then slowly adding the film forming agent and the residual basic oil, sufficiently stirring, completely dissolving, cooling to the room temperature, detecting, discharging the material, thus obtaining the antirust oil. The antirust oil of the invention is high inactually completely drying speed and has good antirust effects for the long-term storage and transportation of various metals such as iron, copper, aluminum, magnesium alloy and the like.

Example Embodiment

[0053] In one embodiment, the present invention also discloses a method for preparing anti-rust oil, which includes the following steps:

[0054] Add most of the base oil to the reactor and heat and stir. When the temperature rises to 90-120°C, add rust inhibitors, cosolvents, and antioxidants, stir well to dissolve them completely, and reduce the temperature in the reactor to 50- At 80°C, slowly add the film-forming agent and the remaining base oil, fully stir until the dissolution is complete, cool to room temperature, detect the discharge, and complete the preparation;

[0055] Among them, the mass fraction of each component is: 20-35% film-forming agent, 5-15% rust inhibitor, 0.1-5% cosolvent, 0.1-2% antioxidant, 40-75% base oil;

[0056] Wherein, the film forming agent is any one or a combination of t-butylphenol formaldehyde resin, petroleum resin, lanolin, rosin and maleic anhydride.

[0057] Preferably, the rust inhibitor is any one or a combination of barium petroleum sulfonate, sodium petroleum sulfonate, barium dinonylnaphthalene sulfonate, and benzotriazole.

[0058] Preferably, the co-solvent is any one or a combination of span, ethanol, xylene, acetone, and ethyl acetate.

[0059] Preferably, the antioxidant is one or a combination of styrene-butadiene rubber, 2,6-di-tert-butyl-p-cresol, pentaerythritol ester, and alkyl diphenylamine.

[0060] Preferably, the base oil is any one or a combination of two kinds of solvent oils of No. 120 and No. 200.

[0061] In a preferred embodiment, the present invention discloses an anti-rust oil comprising the following components in weight percentage: 20-35% film-forming agent, 5-15% anti-rust agent, 0.1-5% cosolvent, anti-rust oil Oxidizer 0.1-2%, base oil 40-75%;

[0062] Among them, the film-forming agent is prepared from the following parts by mass of raw materials: 20-40 parts of tert-butylphenol formaldehyde resin, 5-15 parts of petroleum resin, 10-20 parts of lanolin, 5-10 parts of rosin, 10 parts of maleic anhydride -20 parts, solvent oil 20-40 parts, xylene 5-10 parts;

[0063] The preparation method is as follows: Add most of the prepared base oil into the reaction kettle and heat and stir. When the temperature rises to 90-120°C, add the prepared rust inhibitor, cosolvent, and antioxidant, stir fully to make it completely dissolved, and react The temperature in the kettle is lowered to 50-80°C, and then the film-forming agent and the remaining base oil are slowly added, fully stirred until the dissolution is complete, cooled to room temperature, the material is detected and the preparation is completed.

[0064] In another preferred embodiment, the present invention discloses a preparation method of anti-rust oil:

[0065] Step 1. Make a film-forming resin, put rosin and maleic anhydride into the reactor, heat up to 90±5°C, stir, and add one or more of xylene, tert-butylphenol formaldehyde resin, petroleum resin, and lanolin in sequence , Raise the temperature to 140±10℃ and keep it for 1 hour;

[0066] Step 2. When the temperature in Step 1 drops to 80-90°C, add a part of the prepared base oil to the reaction kettle and stir to prepare a film-forming resin and take it out for use;

[0067] Step 3. Add the remaining base oil to the reactor and stir, add the prepared anti-rust agent, co-solvent, and antioxidant, raise the temperature to 60-70°C, stir fully to make it completely dissolved;

[0068] Step 4. The internal temperature of the reactor is reduced to 50-60°C, and then the film-forming agent of step 2 is slowly added, fully stirred, cooled to room temperature, sampled for inspection, filtered after passing the test, and the preparation is completed.

Example Embodiment

[0070] Example 1

[0071] In this example, the raw materials were prepared according to the ratio (weight percentage) shown in Table 1.

[0072] Step one, put the rosin and maleic anhydride into the reaction kettle, heat up to 90±5°C, stir, add tert-butylphenol formaldehyde resin and lanolin in sequence, heat up to 140±10°C, and keep it for 1 hour.

[0073] Step 2: When the temperature drops to 80-90°C, add part of the base oil to the reaction kettle and stir to prepare a film-forming resin, which is kept for later use.

[0074] Step 3: Add the remaining base oil to the empty reaction kettle and stir, add rust inhibitor, cosolvent, and antioxidant, raise the temperature to 60-70°C, stir well to make it completely dissolved.

[0075] Step 4: The internal temperature of the reaction kettle is lowered to 50-60°C, and then the film-forming resin obtained in Step 2 is slowly added, fully stirred, cooled to room temperature, sampled for inspection, filtered after passing the test, and the preparation is completed.
