Embodiment 1～3

[0025] According to the mass percentage configuration of each component listed in Table 1, the configuration method is as follows:

[0026] Production process of component A: Add water-based silicon-modified polyurethane resin into a stirrable container, then add color paste, defoamer, dispersant and composite wear-resistant powder in proportion under slow stirring, and then mix and stir evenly at high speed Filtration, packaging;

[0027] B component production process: B component is water-based polyurethane curing agent directly filtered and packaged;

[0028] Components A and B are packaged independently, and they are mixed according to the mass ratio A:B=10:1 when used.

[0029] Each component ratio in table 1 embodiment 1-3

[0030]

[0031]

[0032] Among them, the water-based silicon-modified polyurethane resin in component A is domestic, the color paste, dispersant, and defoamer are water-based general domestic materials, and the composite wear-resistant powde...

Abstract

The invention provides a special anticorrosive material used for carbon steel and capable of replacing stainless steel and a preparation method, and relates to the field of new materials. The specialanticorrosive material comprises a component A and a component B, wherein the mass ratio of the component A to the component B is 1: (0.1-0.3); the component A comprises, in percentages by weight, water-based silicon modified polyurethane resin, a color paste, a dispersing agent, a defoaming agent and composite wear-resistant powder; and the component B is a waterborne polyurethane curing agent. The novel material provided by the invention can be used for coating the surface of carbon steel, solves the problems of easy rusting and poor corrosion resistance for the carbon steel and high processing cost of the stainless steel; the material can also be applied to corrosion prevention of various metal structures; the properties like chemical resistance, temperature resistance and corrosion resistance of the material are greatly improved; and the material has wide application prospect and market value.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a special anti-corrosion material for carbon steel instead of stainless steel and a preparation method. Background technique [0002] At present, the sour oil and gas fields in the Bohai Sea area have high carbon dioxide concentration, and conventional stainless steel pure materials or linings are used for anticorrosion, but the procurement and manufacturing of equipment and pipeline raw materials are long, and the triethylene glycol regeneration system is on the critical path of the project schedule, becoming a project Bottleneck for early production. In the face of the huge pressure of "double 20%" in engineering construction, carbon steel + acid-resistant inner coating instead of pure stainless steel or inner lining may become an effective way to solve this situation. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome t...
