Abstract

The invention provides a composite volatile corrosion inhibitor and an application thereof in anticorrosion protection of large equipment, and belongs to the technical field of anticorrosion and antirust materials. The composite volatile corrosion inhibitor comprises, by weight, 10-55 parts of sodium tungstate, 10-55 parts of sodium molybdate, 10-55 parts of 2-methylimidazole, and 0-35 parts of urea. The composite volatile corrosion inhibitor is dissolved in water or absolute ethyl alcohol and then coats textiles, an obtained textile material containing the composite volatile corrosion inhibitor is matched with other textiles to prepare a multilayer composite anticorrosion protection cover, and then high-efficiency anticorrosion protection can be carried out on the large equipment in a simple warehouse or an open-air natural environment through non-strictly closed simple operations such as coating, and bundling; and the composite volatile corrosion inhibitor is reusable, convenient touse and low in cost, the mobility of the integral equipment is guaranteed, the good technical state of the equipment in service is effectively maintained, and the integral support capability of the equipment is improved.

Description

technical field

[0001] The invention belongs to the technical field of anti-corrosion and anti-rust materials, and relates to a composite gas-phase corrosion inhibitor and its application in large-scale equipment anti-corrosion protection. Background technique

[0002] In the southeastern coastal areas of my country, due to natural environments such as high temperature, high humidity, and high salt spray, the corrosion of metal structural parts has always been a major problem that has restricted the management and use of equipment, seriously affecting the technical performance of various equipment and facilities. Due to limited conditions, in-service equipment is usually stored in ordinary warehouses or outdoors, and corrosion problems are very prominent.

[0003] At present, in the storage and storage of equipment, the method of strictly sealing the envelope or introducing protective gas into it is mainly used to slow down atmospheric corrosion. There are the following out...
