Problems solved by technology

[0004] The object of the present invention is to provide an environment-friendly thixotropic anti-rust oil, which solves the problem of environmental pollution and personal injury caused by the anti-rust oil containing soluble barium salts in the prior art after decomposition. At the same time, it is necessary to solve the problem that the anti-rust oil coating is easy to flow on the surface of the workpiece, resulting in a short anti-rust time, and the technical problem that the anti-rust effect is poor during long-term transportation with high salt and high humidity at sea

Abstract

The invention discloses environment-friendly thixotropic antirust oil which consists of the following raw materials in parts by weight: 57-65 parts of paraffin-based base oil, 9-16 parts of naphthenic base oil, 6-11 parts of alkyl high-boiling residue base oil, 5-10 parts of barium-free antirust agent, 1-4 parts of thixotropic agent, 0.2-0.5 part of a phenolic antioxidant, 0.1-0.5 part of an anilino antioxidant, 0.2-1 part of an olefine acid antioxidant and 2-3 parts of a coalescing agent. The invention also provides a method for preparing the environment-friendly thixotropic antirust oil. The environment-friendly thixotropic antirust oil does not contain harmful barium salt decomposed substances and is environment-friendly; the product can rapidly form a stable oil film on the elevation face of a workpiece and does not flow away and waste is reduced; the antirust oil has excellent high temperature resistance, heat and humidity resistance, excellent high-salinity salt mist erosion resistance and excellent antirust performance, has good voltage resistance and is conveniently used for electrostatic spraying; and moreover, the antirust oil has good cleaning performance, and the antirust oil film can be easily removed by using neutral or alkaline water-based cleaning agents.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to antirust oil, in particular to an environment-friendly thixotropic antirust oil and a preparation method thereof. Background technique [0002] In the field of metal machining, since the metal workpiece needs to go through multiple processing processes from the blank to the finished product, the original reserve parts cannot be processed in the next process in a short period of time, so they need to be stored in the warehouse. Metals will be more or less corroded due to different surrounding environments. Especially with the vigorous development of global multinational procurement of components, 80%-90% of the total domestic import and export cargo transportation is completed by sea. However, due to the long sea transportation process, high temperature, high heat and high humidity at sea And high salt spray erosion, the natural conditions are very complex, the workpiece is easil...
