Problems solved by technology

Although the oil solubility of calcium dinonylnaphthalene sulfonate is better than that of barium petroleum sulfonate, its antirust performance is similar to that of barium petroleum sulfonate, and it cannot achieve the purpose of increasing adhesion and long-term rust prevention when used in antirust agents
[0005] Aiming at the defects of relatively short anti-rust period, low adhesion, environmental pollution and harmful health of the metal anti-rust agent products in the prior art, in order to improve the anti-rust function, durability and adhesion of the anti-rust agent, a metal anti-rust Agents and their preparation methods need to be developed urgently

Abstract

The invention relates to a metal hard film antirust agent and a preparing method thereof, and belongs to the technical field of antirust agents. The metal hard film antirust agent is synthesized and compounded from petroleum cracking C5 fractions, organic polyhydric alcohols, stearic acid imidazoline quaternary ammonium salt compounds, triethanolamine oleate, potassium molybdate and sodium pyrophosphate to obtain the metal hard film antirust agent, 12-oxystearic acid imidazoline quaternary ammonium salt is added and adsorbed to the metal surface through polar atoms N and S in molecules to forma protection film, and the antirust capacity of the protection film is further enhanced. The long-acting antirust property is realized in a metal structural member, and the metal hard film antirust agent has the advantages of being high in corrosion resistance, low in cost, convenient to use, easy to construct, easy to remove, quick in coating drying, good in antirust effect, even and attractivein film coating and the like. The raw materials used by the preparing method are low in price, and the process is simple. The requirements for before-assembling early protection and storage early anti-corrosion protection in the engineering mechanical industry can be met, and the metal hard film antirust agent can be applied and popularized in the engineering mechanical industry.

Description

technical field [0001] The invention relates to a metal antirust agent and a preparation method thereof, more specifically to a metal dura film antirust agent and a preparation method thereof, and belongs to the technical field of antirust agents. Background technique [0002] The problem of metal corrosion pervades all industries of the national economy. Rust on the surface of metal materials and mechanical equipment will damage the performance and commodity value of metal products and mechanical equipment, and even cause major failures and make the equipment scrapped. With the development, transformation and upgrading of the equipment manufacturing industry, in order to solve the corrosion of metal products or products in the process of mechanical processing instead of oil washing or degreasing and rust removal, between coating and electroplating processes, as well as after oxidation and phosphating, it is necessary Anti-rust treatment of metal parts with anti-rust agent. ...
