Embodiment 1

[0028] a) First prepare a scaly two-dimensional metal coordination polymer, the composition formula is as follows:

[0029] serial number

[0030] According to the dosage of the scale-like two-dimensional metal coordination polymer formula, add polysulfide rubber and polyethersulfone resin solution to the mixed solvent of xylene, n-butanol and acetone successively, and dissolve them completely under stirring And stir evenly, then add metal cobalt powder, continue to stir until evenly dispersed. Add it to the multi-functional nano-dispersion equipment, adjust the rotation speed to 360 rpm, and grind for 3.5-4 hours to control the diameter of the cobalt powder to about 50nm. Take it out for use.

[0031] b) preparation of mixed solvents,

[0032] serial number

[0033] According to the feeding amount of the mixed solvent formula, pyrrolidone, N,N dimethylformamide, diacetone alcohol, cyclohexanone, methyl ethyl ketone, isophorone and toluene were successivel...

Embodiment 2

[0038] According to the process and proportioning in step a) and step b) in Example 1, prepare a scaly two-dimensional metal coordination polymer and a mixed solvent, and then prepare three-component polymer flooding special-effect two-dimensional metal flake anti-corrosion and anti-scaling coatings Preparation, the ratio of materials is as follows:

[0039] serial number

[0040] First add the mixed solvent into the seasoning tank, under continuous stirring, successively dissolve the silicon-based phenol modified polyethersulfone resin and polytetrafluoroethylene micropowder, make them dissolve and stir evenly, and then add the scaly metal polymer , aluminum powder suspending agent and defoamer, etc., after stirring at a high speed to make them evenly dispersed, pump them into a horizontal sand mill for multiple sand mills to make the fineness reach 5um, then filter and pack.

Embodiment 3

[0042] According to the process and proportioning in step a) and step b) in Example 1, prepare a scaly two-dimensional metal coordination polymer and a mixed solvent, and then prepare three-component polymer flooding special-effect two-dimensional metal flake anti-corrosion and anti-scaling coatings, The material ratio is as follows:

[0043] serial number

[0044] First add the mixed solvent into the seasoning tank, under continuous stirring, successively dissolve the silicon-based phenol modified polyethersulfone resin and polytetrafluoroethylene micropowder, make them dissolve and stir evenly, and then add the scaly metal polymer , aluminum powder suspending agent and defoamer, etc., after stirring at a high speed to make them evenly dispersed, pump them into a horizontal sand mill for multiple sand mills to make the fineness reach 5um, then filter and pack.

Abstract

The invention provides an anti-corrosion and anti-scaling coating. The coating is composed of 18-22 parts of polyethersulfone resin modified by silicon-based phenol, 4-6 parts of polytetrafluoroethylene micropowder, and scale-like two-dimensional metal coordination It consists of 8-12 parts of polymer, 68-72 parts of mixed solvent, 0.08-0.12 parts of aluminum powder suspending agent, and 0.03-0.06 parts of defoaming agent. The surface of the coating of the present invention has ceramic properties, high hardness, corrosion resistance, erosion resistance, and strong scratch resistance; it solves the special corrosion problem of the coating under the harsh environmental conditions of the three-component polymer flooding compound fluid; and improves the combination with the resin Ability to disperse evenly in the coating film.

Description

technical field [0001] The invention relates to a heavy-duty anti-corrosion and anti-scaling coating, in particular to an anti-corrosion and anti-scaling coating used in the working condition of using a three-component polymer flooding compound fluid as an oil displacement agent during oil recovery in an oil field and a preparation method thereof. Background technique [0002] According to the requirements of the "Eleventh Five-Year Plan" of Daqing Oilfield, the oilfield vigorously promotes the use of ASP flooding system for tertiary oil recovery, which can increase the recovery rate by about 20%, but serious corrosion problems of oil well pipes under such harsh environmental conditions have emerged. Therefore, it is very necessary to develop a high-efficiency anti-corrosion and scale-inhibiting coating that can reduce the corrosion rate of oil well pipes under the ASP flooding compound fluid system. The development of a coating with excellent properties such as heavy-duty a...
