Problems solved by technology

[0002] In the prior art, lightning arresters are generally exposed at high altitudes and are often attacked by acid rain or alkaline substances. They are easily corroded and damaged, causing them to lose their function and cause great harm. A layer of paint is applied on the outer wall of the arrester, but the paint is easy to fall off during long-term use, and the paint is easily damaged by acid and alkali components, which greatly reduces the service life of the arrester

Abstract

The invention relates to an acid-base erosion-resistant arrester external protective coating which is prepared from, by weight parts, 82-90 parts of natural rubber, 3-8 parts of methylol aliphatic amines, 2-4 parts of zinc stearate, 40-50 parts of nitrile rubber, 100-120 parts of ethylene propylene rubber, 2-7 parts of zinc oxide, 3-7 parts of magnesium oxide, 25-30 parts of butadiene-styrene rubber, 2-9 parts of chlorinated paraffin, 3-7 parts of methanol, 9-16 parts of dibutyl phthalate, 2-6 parts of polylactic acid, 9-15 parts of polystyrene, 4-5 parts of calcium naphthenate, 5-6 parts of titanium dioxide, 5-6 parts of zinc oxide, 35-45 parts of fluororubber, 1-2 parts of smoked sheet rubber, 12-14 parts of diethylene glycol dibenzoate, 7-11 parts of activated Calcium carbonate, 4-8 parts of cumarone, 6-9 parts of dipropylene glycol dibenzoate and 30-34 parts of aluminum nitride.

Description

technical field [0001] The invention relates to the technical field of lightning arresters, in particular to an acid and alkali corrosion-resistant outer protective coating of the lightning arrester. Background technique [0002] In the prior art, lightning arresters are generally exposed at high altitudes and are often attacked by acid rain or alkaline substances. They are easily corroded and damaged, causing them to lose their function and cause great harm. A layer of paint is applied on the outer wall of the arrester, but the paint is easy to fall off during long-term use, and the paint is easily damaged by acid and alkali components, so that the service life of the arrester is greatly reduced. Contents of the invention [0003] In view of this, it is necessary to provide an acid and alkali corrosion-resistant outer protective coating of the arrester. [0004] The present invention is achieved in this way, an acid and alkali corrosion resistant lightning arrester exter...
