Abstract

The invention discloses an environmentally-friendly barium-free thixotropic antirust oil, which is characterized by comprising the following components in percentage by weight: antirusting agent 4.0-25.0, thixotropic agent 0.1-5.0, antioxidant 0.1-3.0 and base oil 72.0-94.0. The preparation method of the environmentally-friendly barium-free thixotropic antirust oil comprises: firstly, adding the base oil into a reaction kettle, stirring the base oil, heating the base oil to 110 to 120 DEG C, adding the antirusting agent, stirring the mixture for continuous dehydration for 1 hour, and cooling the mixture to 50 to 60 DEG C; and secondly, adding the antioxidant, stirring the mixture for 3 hours at a constant temperature of 50 to 60 DEG C, adding the thixotropic agent, stirring the mixture for1 hour at 50 to 60 DEG C, cooling the resulting product to 40 DEG C, filtering the resulting product and discharging the resulting product. For obtaining antirust oil films that are insusceptible toflow and free from heavy metal barium, the antirust oil selects a proper barium-free corrosion inhibiter to ensure excellent antirust performance besides the thixotropic agent added for quickly forming stable oil films of antirust oil.

Description

technical field [0001] The invention relates to an antirust oil used for steel corrosion protection, in particular to an antirust oil with thixotropic properties and containing no barium elements, which is environmentally safe and belongs to the technical field of metal surface treatment. Background technique [0002] Anti-rust oil has been widely used at home and abroad due to its advantages of good effect, convenient use, low cost, easy construction, simple operation and easy removal. Because barium-containing corrosion inhibitors (such as barium petroleum sulfonate, barium dinonyl naphthalene sulfonate) have excellent antirust performance, barium-containing corrosion inhibitors are basically listed as preferred components in existing antirust oils , for example, publication number is CN1629264 Chinese invention patent application "preparation method of a kind of anti-rust oil", publication number is CN101144046 Chinese invention patent application "manufacturing method of...
