Anticorrosion paint for decorating inner and external walls of power station transformer, and preparation thereof

Abstract

The invention provides anticorrosive paint for inner and outer wall decoration of a power station transformer, which comprises main paint and a curing agent. The anticorrosive paint is characterized in that the main paint and the curing agent of outer wall paint are prepared according to the proportion of 5:1, the main paint and the curing agent of inner wall paint are prepared according to the proportion of 8:1, and the curing agent is IPDI tripolymer-modified HDI biuret. The inner wall paint of the power station transformer has excellent oil resistance, and a paint film can still show good protection property and electrical insulating property when being soaked in transformer oil with a temperature of between 90 and 110 DEG C for a long time. The outer wall paint of the power station transformer has excellent weather resistance, can effectively improve the protection property, and can prolong the service life of equipment, reduce maintenance cost and power cut loss, and improve power transmission efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of new materials, in particular to a decorative anticorrosion paint for inner and outer walls of power station transformers. Background technique: [0002] With the continuous development of my country's power transmission and distribution technology, the technology of transformers, especially large transformers, has also made great progress. Alkyd-type and alkyd-type transformer paints not only affect the dielectric loss of transformer oil, but also have low anti-corrosion and decorative performance, which can no longer adapt to new technical requirements. The acrylic polyurethane interior and exterior wall decorative anti-corrosion paint (two-component) modified by ACE and epoxy resin has better film-forming performance than the matrix polymer, and can form an interpenetrating network to form a "polymer alloy" (IPN structure). The coating film performance not only has polyurethane hard wear resistance and...

Problems solved by technology

[0002] With the continuous development of my country's power transmission and distribution technology, the technology of transformers, especially large transformers, has also made great progress, and the requirements for anti-corrosion decoration of the inner and outer walls of transformers are also getting higher and higher. In the past, epoxy-polyamide type, polyurethane Alkyd-type and alkyd-type transformer paints not only affect the dielectric loss of transformer oil, but also have low anti-corrosion and decorative performance, which can no longer adapt to new technical requirements.
