Problems solved by technology

The corrosion of metal equipment not only consumes precious wealth, but also destroys the normal operation of production and life
Corroded metal equipment will deteriorate in shape, color, and mechanical properties, leading to equipment damage, serious waste of resources and energy, and even serious accidents
[0003] Traditional anti-corrosion coatings are not ideal for the corrosion protection of the base metal due to the limitations of their own material properties and processes, and a considerable part of the coatings contain toxic substances such as lead or chromate, which are polluted during preparation and use. Environmental hazards, which are not compatible with the requirements of the socio-economic sustainable development strategy
At present, most of the commonly used anti-corrosion coatings are epoxy zinc-rich paints, but in the prior art, the dry film metal zinc content based on epoxy zinc-rich paints is more than 80%, and the adhesion of the coating and the mechanical impact resistance The performance will decrease with the increase of zinc content, and the salt spray resistance will also decrease, so that the coating is easily damaged by external force during the construction process, which will affect the corrosion resistance of the coating

Abstract

The invention provides an anticorrosive material for metallic equipment. The material comprises a rubber-asphalt anticorrosive coating material and an organic acid type curing agent, wherein the organic acid type curing agent consists of one or more of citric acid type curing agent, sorbic acid, amino naphthalene disulfonic acid and tartaric acid, and an anti-rusting agent is added in the rubber-asphalt anticorrosive coating material and is prepared from one or more of zinc phosphate, modified zinc phosphate and zinc molybdate, a surfactant, a wetting agent, a dispersing agent and deionized water. According to the anticorrosive material for the metallic equipment and the preparation and construction methods thereof, the anti-rusting agent is innovatively added in the anticorrosive material for the metallic equipment, so that the anticorrosive material for the metallic equipment, prepared by using the anti-rusting agent, has more excellent corrosion resistance while guaranteeing environmental friendliness; meanwhile, the weather resistance is very excellent, and the service life of the metallic equipment is greatly prolonged; the organic acid type curing agent, of which the corrosiveness to metal can be neglected, is used innovatively, and the required curing performance can be effectively guaranteed by the organic acid type curing agent.
