Embodiment 1
[0033] This embodiment relates to a kind of antirust oil for magnesium alloy and its preparation method;
[0034] The raw material ratio of the anti-rust oil is: 40% of paraffin-based 150SN mineral oil, 40% of dibutyl sebacate, 3% of benzotriazole derivatives, 2,6-di-tert-butyl p-cresol 2 %, compound anti-rust additive 15%.
[0035] The composite antirust additive is a mixture of low base value synthetic calcium sulfonate, 12 alkenyl succinate and 17 imidazolinyl succinate with a mass dosage ratio of 3:0.2:0.8.
[0036] The preparation method is: in the base liquid (paraffin base MVI 150 base oil), add polyol ester synthetic base oil (dibutyl sebacate), benzotriazole derivatives, 2,6-di-tert-butyl p-cresol and composite anti-rust additives are dispersed at 40°C for 80 minutes by high-speed stirring at a speed of 2000-3200rpm / min to obtain a highly refined colloidal solution; the solution is heated to 70°C and dynamically mixed The device dispersion was prepared in base oil (...
