Abstract

The invention relates to a plastic enhanced special anticorrosion paint and a preparation method therefor. For traditional paints on surfaces of oil field and mine field steel materials, a film forming substance is mostly one or two thermosetting materials, the surface is hard after curing molding, the flexibility is poor, the brittleness is high, and a tensile force and a compressing force cannot be resisted. High chlorinated polyethylene, vinylidene chloride and a solvent a are mixed, the mixture is stirred uniformly at a high speed and then placed; precipitated barium sulphate, calcined kaolin, pigment, acrylic resin and the solution obtained in the first step are mixed, the mixture is dispersed uniformly at a high speed and then is allowed to stand, the mixture is added on a grinder and ground, and a solution is obtained; the solution obtained in the second step is added in a solvent b, dispersion is carried out in a dispersion machine at a high speed, the viscosity is adjusted and a product is obtained. The film forming substance different from traditional paints is employed, and the performances of the film forming substance after curing are between plastic and rubber. On the premise of various protruding anticorrosion performances, the good mechanical property is achieved, and the bending and flexibility performances are protruding.

Description

technical field [0001] The invention belongs to the technical field of surface anticorrosion of steel materials in oil fields and mines, and in particular relates to a plastic-reinforced special anticorrosion coating and a preparation method thereof. Background technique [0002] With the increasing application of anti-corrosion coatings in severe corrosion situations such as oil fields and mines, the requirements for anti-corrosion performance are also getting higher and higher. Conventional anti-corrosion coatings only pay attention to anti-corrosion performance, but do not have outstanding effects on the mechanical properties of the coating after forming, so its service life is limited. In recent years, research on equipment in oil fields and mines has shown that after the equipment receives collisions and impacts, due to the forces such as stretching and bending, the coating will peel off and even cracks will appear, which will eventually lead to the destruction of the c...
