Example Embodiment

[0048] refer to figure 1 , which shows a flowchart of a preparation method of the rubberized asphalt anti-corrosion coating in an anti-corrosion material for metal equipment according to an embodiment of the present invention, and the preparation method specifically includes:

[0049] Step 101 , the preparation of the vulcanized rubber-modified anionic emulsified asphalt: mix the asphalt and the vulcanized rubber and emulsify to prepare the vulcanized rubber-modified anionic emulsified asphalt.

[0050] Step 102, the preparation of the rust inhibitor: adding one or more of zinc phosphate, modified zinc phosphate and zinc molybdate, and wetting agent, deionized water and surfactant in sequence in proportion to prepare the antiseptic Crude product, disperse the crude product of the rust inhibitor at a rotational speed of 1000-2000 r / min for 1 hour, and then grind the dispersed crude product of the rust inhibitor for 1 hour to obtain the rust inhibitor .

[0051] Step 103, prep...

Example Embodiment

[0059] Example 1

[0060] When preparing the anti-corrosion coating of rubber asphalt in the anti-corrosion material for metal equipment, 63 kg of asphalt and 27 kg of vulcanized rubber were mixed and emulsified to obtain 90 kg of vulcanized rubber-modified anionic emulsified asphalt.

[0061] Add 0.1kg of rosin soap and fatty acid soap, 0.1kg of wetting agent, 0.1kg of polynaphthalenesulfonic acid sodium salt, 0.1kg of deionized water and 0.1kg of zinc phosphate and mix to obtain the crude rust inhibitor. The rust inhibitor crude product was dispersed at a rotational speed of 1000 r / min for 1h, and then the dispersed rust inhibitor crude product was ground for 1h to obtain a total amount of 0.5kg of the rust inhibitor. .

[0062] Mix 0.1kg of rosin soap and fatty acid soap, 0.1kg of dispersant, 0.1kg of sodium alkyl sulfate, 0.1kg of hindered amine light stabilizer, 0.1kg of defoamer and 0.1kg of anti-aging agent at 500r / min. The additive was mixed and dispersed for 1 h und...

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.

Description

technical field [0001] The invention relates to the field of material technology, in particular to an anti-corrosion material for metal equipment, a preparation method for the anti-corrosion material for metal equipment, and a construction method for the anti-corrosion material for metal equipment. Background technique [0002] Corrosion of metal materials is a worldwide problem. 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 durin...
