preparation example Construction

[0053] In one embodiment, the present invention also discloses a preparation method of antirust oil, comprising the following steps:

[0054] Add most of the base oil into the reactor and heat and stir. When the temperature rises to 90-120°C, add rust inhibitor, co-solvent, and antioxidant, stir well to dissolve it completely, and lower the temperature in the reactor to 50-120°C. 80°C, then slowly add the film-forming agent and the rest of the base oil, stir well until the solution is completely dissolved, cool to room temperature, check the output, and complete the preparation;

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

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

[0057] Preferably, the rust inhibitor is any one or a ...

Embodiment 1

[0071] The present embodiment calculates the raw materials according to the proportioning (percentage by weight) shown in Table 1.

[0072] Step 1: put rosin and maleic anhydride into the reactor, raise the temperature to 90±5°C, stir, add tert-butylphenol formaldehyde resin and lanolin in sequence, raise the temperature 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 into the reaction kettle and stir to prepare a film-forming resin, and keep it for later use.

[0074] Step 3: Add the rest of the base oil into an empty reactor and stir, add rust inhibitor, co-solvent, and antioxidant, raise the temperature to 60-70°C, and fully stir to dissolve it completely.

[0075] Step 4: The internal temperature of the reactor is lowered to 50-60°C, and then slowly add the film-forming resin obtained in Step 2, stir well, cool to room temperature, take a sample for inspection, and filter after passing the test to comple...

Embodiment 2-3

[0080] The experimental procedure is the same as in Example 1, the only difference being that the ratio of raw materials 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...
