Abstract

The invention discloses a preparation method of a wear-resistant toughened anticorrosive adhesive. The anticorrosive adhesive is a light grey viscous liquid, and is prepared from an epoxy resin (or polyurethane), vulcanized rubber, acetone (or xylene), a phenolic resin (or fatty acid diethylenetriamine), polyisobutylene, polymerized rosin, an antioxidant 1010 and mica iron oxide (alpha-Fe2O3) according to certain proportion. The novel anticorrosive adhesive has the advantages of high vertical attachment peel strength, water resistance, heat resistance, impact resistance, corrosion resistance and simple construction technique, can be cured to form a film at normal temperature, is suitable for corrosion resistance of steam condenser copper pipe ends and seepage prevention of copper pipe expanded openings, and can also be used for corrosion resistance and seepage prevention of similar equipment.

Description

technical field [0001] The invention relates to a preparation method of an anti-corrosion and anti-seepage material for a condenser of a condensing power plant. Specifically, it relates to a preparation method of a novel anti-corrosion glue. The anti-corrosion adhesive can be used for anti-corrosion and anti-seepage of similar equipment in addition to the anti-corrosion of copper pipe ends of condensers and the anti-seepage of copper pipe expansion. Background technique [0002] The condenser is an important part of the generator set. Once the condenser has quality problems, it will cause huge losses to the production of the entire thermal power plant. Due to the particularity of the working environment of the condenser, the condenser is prone to corrosion during its use. The corrosion of the condenser is mainly the corrosion of its copper pipes. Corrosion and fouling of steam turbines. The study found that 38% of large-scale thermal power generation unit corrosion accide...
