Abstract

The invention discloses anticorrosion paint used for cables and a preparing method thereof, and relates to the technical field of paint. Raw materials of the paint include 55-65 parts of water-absorbent resin, 45-55 parts of modified rubber powder, 39-41 parts of styrene-acrylic emulsion, 39-41 parts of modified starch, 34-36 parts of a filler, 29-31 parts of glass wool, 20-25 parts of an auxiliary agent and 65-75 parts of water. After the paint is used on the surfaces of cables, bonding properties are stronger, ageing resistance and corrosion resistance are excellent, the paint is free of cracks after long-term use, and stability is high.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-corrosion coating for cables and a preparation method thereof. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer opening. The outer layer of the cable wire is coated with a layer of paint for protection and has the performance of insulation and fire prevention. However, due to the complexity of the use environment of the cable, the coating is prone to aging, cracking and corrosion when used in a long-term high-tempe...
