Abstract

The invention relates to the technical field of antirust technology for copper materials, specifically to antirust oil for copper materials and a preparation method and application thereof. The antirust oil for copper materials comprises the following raw materials (by weight): 82-88 parts of solvent naphtha, 4-8 parts of base oil, 3-6 parts of an antirust film forming agent, 1-2 parts of a cosolvent, 0.3-0.6 part of a corrosion inhibitor, and 0.01-0.05 part of a dehydrant. The invention has the following beneficial effects: the antirust oil for copper materials contains no barium antirust agent, phthalate or toxic compounds such as aromatic hydrocarbons, etc., is environmentally-friendly, is safe to use, has thin oil film, and has excellent oxidation resistance and good antirust effect. The preparation method has simple process and is convenient for industrial production. The application method of the antirust oil for copper materials is simple. Treated copper materials can meet higher salt spray test requirements and indoor storage requirements.

Description

technical field [0001] The invention relates to the technical field of antirust for copper materials, in particular to an antirust oil for copper materials, its preparation method and its application. Background technique [0002] Disadvantages of current anti-rust oil for copper: oily anti-rust oil, too thick oil film, which affects electrical conduction and welding, and also affects aesthetics. Volatile anti-rust oil, most of which use barium petroleum sulfonate and benzotriazole as corrosion inhibitors , has a certain anti-rust effect on copper, but it is difficult to meet higher salt spray test requirements and indoor storage requirements. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, one of the objectives of the present invention is to provide a copper antirust oil which is a volatile antirust oil with a thinner oil film and forms a dense and stable layer on the surface of the copper. The complex has the f...
