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 sulfona...

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 pre...

Example Embodiment

[0079] Example 2-3

[0080] The experimental procedure is the same as that of Example 1, except that the raw material ratio shown in Table 1 is different.

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.

Description

technical field [0001] The invention relates to the technical field of corrosion prevention, in particular to an antirust oil and a preparation method thereof. Background technique [0002] At present, there are many types of anti-corrosion products commonly used, such as anti-rust oil, water-based anti-rust liquid and gas phase anti-rust, etc., as well as anti-corrosion paint, anti-rust paint or electroplating coating. However, most of these products have shortcomings such as too short anti-rust time, easy cracks in the anti-rust film, slow drying speed after coating, and too thick film. There are also good and bad anti-rust oils on the market. Among them, some products have insufficient coating hardness, poor weather resistance, and some are opaque. However, the damp heat resistance and salt spray resistance of ordinary hard film antirust oils are not ideal. Other metals have poor protection. Contents of the invention [0003] In view of the above-mentioned shortcomin...
