Problems solved by technology

Dacromet is a high anti-corrosion zinc-aluminum composite coating. It is expensive and needs to be baked at a high temperature of 350°C for 60 minutes. The material cost is high and the use is inconvenient, which causes great pressure on users
On the other hand, solvent-based paints have great pollution to the atmospheric environment and do not meet environmental protection requirements.

Abstract

The invention provides an anti-corrosion sampler and a manufacturing method thereof. Cresol formaldehyde epoxy resin is reacted with para aminobenzoic acid, and reactants hereby are neutralized with dimethyl ethanolamine to be salt for preparing anionic surfactant. With the prepared anionic surfactant, water-based macromolecular linear phenolic epoxy resin is emulsified by phase inversion to produce novel water-based environment-friendly high-temperature resistant anti-corrosion painting through strict technical conditions. Via reasonable matching and proportioning, coating the surface layer of the sampler only needs baking at 150 DEG C for 40 minutes. In this way, the sampler can present better resistance to high temperature and corrosion, resistance to stress corrosion, and longer service life and have no pollution to the atmosphere.

Description

technical field [0001] The invention belongs to the technical field of material engineering, and in particular relates to a corrosion-resistant sampler and a preparation method thereof. Background technique [0002] At present, the requirements for corrosion resistance of marine operation equipment are getting higher and higher. The sampler is a common marine operation equipment, which is used to salvage target objects in shallow water areas. In order to reduce the weight of the sampler, the barrel body of the sampler can be made of aluminum alloy, but the barrel body is often ups and downs on the sea surface, and is often located at the seawater-air interface, which is prone to corrosion. [0003] Currently commonly used anti-corrosion materials usually use Dacromet coatings and solvent-based paints. Dacromet is a high anti-corrosion zinc-aluminum composite coating. It is expensive and needs to be baked at a high temperature of 350°C for 60 minutes. The high material cost ...
