Embodiment 1
[0017] (1) The waxy bottom oil is used as the basic raw material, and the waxy bottom oil is light dewaxed bottom oil; the properties of the waxy bottom oil are: no water-soluble acid and alkali, acid value ≤ 0.24mgKOH / g, mechanical impurity content ≤ 0.03%, flash point ≥ 200°C;
[0018] (2) dehydrating the basic raw material at a temperature of 100° C. for 0.5 h;
[0019] (3) add antirust agent barium dinonylnaphthalene sulfonate in the product after dehydration treatment, the consumption of antirust agent is 0.25% of basic raw material quality, is to stir 1h under the condition of 105 ℃ at temperature, obtains kinematic viscosity ( 100℃) is 15.27mm 2 / s, the penetration is 150 (25°C, 150g) 1 / 10mm, the drop melting point is 57.4°C, and the acid value is 0.09mgKOH / g industrial vaseline.
Embodiment 2
[0021] The preparation method of this embodiment is the same as that of Example 1, and the difference is that: the wax lower oil is the second-line wax lower oil, the third-line wax lower oil or the fourth-line wax lower oil, or light dewaxed lower oil , at least two of the second-line waxed oil, the third-line waxed oil and the fourth-line waxed oil; the rust inhibitor is calcium petroleum sulfonate, barium petroleum sulfonate, sodium petroleum sulfonate, magnesium lanolin soap , lanolin aluminum soap or sulfonated lanolin calcium soap. The kinematic viscosity (100°C) of the prepared industrial vaseline is 15.14mm 2 / s~18.82mm 2 / s, the cone penetration is 120(25℃, 150g) 1 / 10mm~200(25℃, 150g)1 / 10mm, the dropping melting point is 46.8℃~62.5℃, the acid value is 0.02mgKOH / g~0.09mgKOH / g .
Embodiment 3
[0023] (1) The waxy bottom oil is used as the basic raw material, and the waxy bottom oil is light dewaxed bottom oil; the properties of the waxy bottom oil are: no water-soluble acid and alkali, acid value ≤ 0.24mgKOH / g, mechanical impurity content ≤ 0.03%, flash point ≥ 200°C;
[0024] (2) Mix the basic raw material and the light dewaxing paste in a mass ratio of 100:2, and dehydrate for 1 hour at a temperature of 110° C.; the properties of the light dewaxing paste are: no water-soluble acid-base, acid value ≤0.24mgKOH / g, mechanical impurity content≤0.03%, flash point≥200℃;
[0025] (3) Add anti-rust agent lanolin magnesium soap to the product after dehydration treatment, the consumption of anti-rust agent is 15% of basic raw material quality, stir 1h under the condition of temperature being 105 ℃, obtain kinematic viscosity (100 ℃) 18.85mm 2 / s, the penetration is 169 (25°C, 150g) 1 / 10mm, the drop melting point is 61.4°C, and the acid value is 0.02mgKOH / g industrial vasel...
