Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the problems of existing anti-rust oils such as poor anti-rust effect, too thick oil film, difficult to remove, etc., and provide a kind of anti-rust oil used in metal processing with thin oil film thickness, easy to remove, and good anti-rust effect. The antirust oil composition and its preparation method can not only meet the function of short-term sealing and antirust during the handprint removal process, but also meet the requirements of long-term sealing and antirust performance in the precision processing room of the soft film

Abstract

The invention relates to an antirust oil composition used for metal processing and a preparation method thereof, solving the problems of poor antirust effect, over thick oil film, difficult removal and the like of the existing antirust oil. The antirust oil composition adopts 15-20% of base oil, 37.5-52% of petroleum sulfonate, 26-35% of high molecular carboxylic acid and soap, 4.5-7% of ester and 0.2-0.5% of benzotriazole and derivative as raw materials and is prepared by heating and stirring. The invention adopts the compounding of various corrosion inhibitors, exerts a complementary and accessorial ultra-effect composite action in the antirust performance, and generates major breakthrough in use performance and the effect, the antirust performance of the invention is far superior to the performance of antirust oil prepared from single agent and completely passes through the test and assessment of an optimizing antirust platform rack, and the invention has excellent moisture resistance and antirust functions, has excellent salt water erosion resistance, water replacement property, acid neutralizing performance and sweat control capability and reaches the quality requirement of a thin multi-effect environment-friendly antirust oil complex additive.

Description

Technical field: [0001] The invention relates to a corrosion-inhibiting surfactant, in particular to an antirust oil composition used in metal processing and a preparation method thereof. Background technique: [0002] According to relevant media statistics, at present, the weight of steel lost due to corrosion and rust in the world is approximately equivalent to 10-20% of the annual metal output. In the United States, the annual direct loss due to steel corrosion is about 137.9 billion US dollars, while the loss of my country's machinery industry in terms of corrosion accounts for about 7.2% of the total output value of the machinery industry, which is estimated to be 60-80 billion yuan per year. Therefore, the direct and indirect losses caused by metal corrosion cannot be ignored, which has attracted the attention of all walks of life. The problem of anti-corrosion has become an important topic in my country's metal processing industry. [0003] At present, there are many...
