Embodiment 1

[0036] Mix 5 parts of sodium petroleum sulfonate and 1 part of dodecenylsuccinic acid, heat to 35°C, and stir until completely miscible and transparent to obtain reddish-brown compound A, which is naturally cooled to room temperature. Add compound A to 50 parts of base oil, stir at room temperature until evenly mixed, and obtain orange-red transparent compound B. Add 1 part of sebacic acid, 1 part of benzotriazole, and 1 part of natural rosin to 4 parts of dimethyl sulfoxide, stir at room temperature until completely dissolved, and obtain yellow solution C. After adding solution C to mixture B, quickly add 37 parts with stirring

[0037] Butanol, a bright yellow transparent liquid.

Embodiment 2

[0039] Mix 7 parts of sodium petroleum sulfonate and 1 part of dodecenylsuccinic acid, heat to 37°C, and stir until completely miscible and transparent to obtain reddish-brown compound A, which is naturally cooled to room temperature. Add compound A to 55 parts of base oil, stir at room temperature until evenly mixed, and obtain orange-red transparent compound B. Add 1 part of sebacic acid, 1 part of benzotriazole, and 1 part of natural rosin to 4 parts of dimethyl sulfoxide, stir at room temperature until completely dissolved, and obtain yellow solution C. After adding solution C to mixture B, quickly add 30 parts with stirring

[0040] Butanol, a bright yellow transparent liquid.

Embodiment 3

[0042] Mix 6 parts of sodium petroleum sulfonate and 1 part of dodecenylsuccinic acid, heat to 40°C, and stir until completely miscible and transparent to obtain reddish-brown compound A, which is naturally cooled to room temperature. Add compound A to 57 parts of base oil, stir at room temperature until evenly mixed, and obtain orange-red transparent compound B. Add 0.5 parts of sebacic acid, 0.5 parts of benzotriazole, and 1.5 parts of natural rosin to 2.5 parts of dimethyl sulfoxide, stir at room temperature until completely dissolved, and obtain yellow solution C. After solution C was added to mixture B, 31 parts of n-butanol was quickly added under stirring to obtain bright yellow transparent liquid.

Abstract

The invention provides environment-friendly barium-free thin-layer antirust oil as well as a preparation method and application thereof. The environment-friendly barium-free thin-layer antirust oil comprises the following components in parts by weight: 5.5-15 parts of an antirust agent, 2-9 parts of a solvent, 20-40 parts of a cosolvent, 0.5-2 parts of an antioxidant, 0.5-2 parts of a film-formingagent and the balance of base oil based on the total weight being 100 parts, wherein the antirust agent is a composite antirust agent of petroleum sodium sulfonate, dodecenylsuccinic acid and sebacicacid, and the weight ratio of the petroleum sodium sulfonate to the dodecenylsuccinic acid to the sebacic acid is (4-10): (1-2.5): (0.5-2.5). The environment-friendly barium-free thin-layer antirustoil disclosed by the invention does not contain heavy metal barium, is low in viscosity, stable in performance and excellent in damp-heat resistance and salt mist resistance, and an oil film is a thinor even ultrathin film.

Description

technical field [0001] The invention belongs to the field of antirust technology, and in particular relates to an environment-friendly barium-free thin-layer antirust oil and its preparation method and application. Background technique [0002] Metal is the most important structural material in modern machinery industry, national defense industry, petroleum industry and other departments, but it is easily deteriorated or damaged by the chemical and electrochemical effects of the external environment or medium. Among them, rust is the most common form of metal corrosion. Rust on the surface will greatly damage the performance and commodity value of metal products and mechanical equipment, and even cause major accidents. The survey results show that the annual economic losses caused by metal corrosion account for 2% to 4% of their gross national product, far exceeding the average annual losses caused by fire, flood, wind, earthquake and other disasters. The indirect losses ca...
