Abstract

The invention discloses an anticorrosive coating for a cable bracket, and belongs to the technical field of cable brackets. The anticorrosive coating is prepared from, by weight, 40-50 parts of epoxyresin, 10-20 parts of chlorinated rubber, 0.5-2 parts of polyaniline, 1-2 parts of zinc phosphate, 1-3 parts of a styrene-acrylic emulsion, 8-12 parts of a stabilizing agent, 1-3 parts of mica powder,1-2 parts of sodium dodecyl benzene sulfonate, 0.5-1.5 parts of a silane coupling agent, 7-10 parts of a curing agent, 10-12 parts of a solvent and 3-5 parts of water. The coating has low raw material cost, excellent corrosion resistance and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of cable supports, in particular to an anti-corrosion paint for cable supports. Background technique [0002] Cable tunnels and cable trenches are the main channels for urban power supply. Cable brackets are required to erect cables in cable trenches and tunnels. Generally, cable brackets are welded by angle iron, but cable trenches or tunnels are generally watery, humid, and may There is also corrosion, and the angle iron is easy to rust, which affects the safety of power supply. Therefore, it is necessary to carry out anti-corrosion or waterproof treatment on the cable support in actual operation. [0003] Chinese patent document (publication number CN109439109 A) discloses a high-performance anti-corrosion coating for ships and a preparation method thereof. The ship's high-performance anti-corrosion coating includes the following raw materials in parts by weight: 60-70 parts of water-based acrylic resin...
