Abstract

The invention discloses an environment-friendly anticorrosive acid-resistant coating which selects epoxide resin E-51 and epoxide resin E-44 as its main base materials, likewise uran epoxide resin or coumarone resin can be added to improve acid-resistivity of the coating. The coating invented by this method does not contain asphalt, is nontoxic and is of no pollution to the surroundings, does not influence the health of the coating makers and builders, and is of strong stick force and good shockproof property, abradability, water resistance, alkali resistance and acid-resistance, and is of long life span and good suitability to various types of priming paint. This coating is mainly used in accumulator flatanti-corrosion or chemical equipmentanti-corrosion.

Description

technical field [0001] The invention relates to an environment-friendly acid-resistant and anti-corrosion coating, in particular to an environment-friendly acid-resistant and anti-corrosion coating used in the battery compartment of a ship or chemical equipment. Background technique [0002] At present, the batteries on ships are mainly lead-acid batteries. When the lead-acid battery is working, the internal water will be electrolyzed into hydrogen and oxygen will escape in the form of gas, and the sulfuric acid electrolyte will be brought out when the gas escapes, forming an acid mist environment in the cabin, corroding various equipment in the cabin and the ship body The material will make the ship unable to work normally, and will cause the hull to perforate in severe cases. When the salty seawater flows into the battery compartment, it immediately reacts with the electrolyte sulfuric acid in the battery to produce toxic chlorine gas, which directly threatens the lives o...
