Abstract

The invention discloses nano-modified anticorrosive coating for power transmission and transformation lines and a preparation method thereof, and belongs to the technical field of electric power corrosion prevention. The coating is prepared from the following raw materials in parts by weight: 50-80 parts of epoxy modified organosilicon resin, 5-10 parts of nano magnesium oxide, 5-15 parts of a coupling agent, 5-12 parts of a curing agent, 30-50 parts of a compound diluent, 4-10 parts of red lead, 2-5 parts of aluminum silicate and 1-6 parts of an auxiliary agent. The coating is good in temperature change resistance and weather resistance.

Description

technical field [0001] The invention relates to the technical field of electric power anticorrosion, in particular to a nano-modified anticorrosion coating for power transmission and transformation lines and a preparation method thereof. Background technique [0002] Power transmission and transformation equipment is often vulnerable to natural factors such as atmospheric corrosion and water corrosion in harsh outdoor environments, which brings great harm to power transmission and transformation lines. In the prior art, corrosion prevention measures mainly adopt anti-corrosion Coating, electroplating and other technologies, a layer of anti-corrosion coating is coated on the outer surface of the steel of power transmission and transformation equipment, usually hot-dip galvanizing technology is generally used in power transmission and transformation anti-corrosion, but the current domestic galvanized coating corrosion resistance Poor, short service life, backward technology, u...
