Anticorrosive power transmission tower outer coating

Abstract

The invention discloses an anticorrosive power transmission tower outer coating and belongs to the technical field of power circuits. The anticorrosive power transmission tower outer coating is prepared from the following raw materials in parts by weight: 30-40 parts of hydroxy acrylic resins, 15-25 parts of polyurethane emulsion, 8-12 parts of a thermal conductive filler, 1-3 parts of calcium sulfate whiskers, 1-3 parts of molybdenum powder, 0.5-1.5 parts of asbestos powder, 0.1-0.2 part of an ultraviolet light absorber, 0.1-0.5 part of sodium methyl silicate, 1-3 parts of polyvinyl alcohol,1-3 parts of polydimethylsiloxane, 1-3 parts of glycerin monostearate and 15-25 parts of an organic solvent. The coating is wear-resistant, acid and alkali resistant, salt spray resistant, excellent in mechanical property and long in service life.

Description

technical field [0001] The invention relates to the technical field of power lines, in particular to an anti-corrosion outer coating for power poles and towers. Background technique [0002] There is a long coastline in the east of my country, deserts, salt lakes and other harsh environments in the west, and there are heavy industrial air pollution or saline areas. Most of the transmission line towers are made of iron materials. The erosion of the sun will cause corrosion of the power poles and towers of the transmission line; thus affecting the safe operation of the transmission line. [0003] Chinese patent document (publication number CN106675354A) discloses an anti-corrosion coating for power poles and towers, which belongs to the field of anti-corrosion coatings; it mainly includes the following raw materials in terms of parts by mass: 28-30 parts of nano-magnetic iron oxide, 10-12 parts of inert diluent , 18-20 parts of alkyd resin, 10-11 parts of polyvinyl alcohol, 7-...

AI Technical Summary

Problems solved by technology

[0004] Chinese patent literature (publication number CN108517142A) discloses a method for preparing insulating coatings for power equipment, including component A and component B. The components of A are as follows in parts by weight: 35-45 parts of hydroxyl acrylic resin, carbon 10-20 parts of nanotubes, 4-10 parts of ceramic powder, 3-5 parts of potassium albite feldspar, 8-12 parts of vacuum glass beads, 3-7 parts of siloxane coupling agent, 4-8 parts of nano barium sulfate , 5-15 parts of nano-titanium dioxide, 10-16 parts of xylene and butyl acetate mixture; the B component is as follows by weight: 10 parts of biuret, strictly control the proportion of each component, and optimize the traditional insulating coating manufacturing Formula, the performance of the insulating coating produced and discharged is more stable, and the open storage time can be extended to 12 hours, which can effectively reduce the waste of insulating coating, save resources, and protect the environment; but this patent does not improve the thermal conductivity of the coating, resulting in the heat dissipation performance of the coating Difference
