Problems solved by technology

[0006] At present, researchers have not conducted a comprehensive study on how to improve the wear resistance, corrosion resistance and scale resistance of the inner wall of the pipe, how to prolong the failure period of the coating through self-lubricating "wear reduction to wear resistance", block the invasion of various corrosion sources, and improve the adhesion of the coating. Improving the low surface energy and high density of the coating to strengthen the antiscaling wax effect is an urgent problem to be solved by those skilled in the art

Abstract

The invention provides a graphene self-lubricating wear-resistant corrosion-resistant scale-inhibiting wax coating agent and a preparation method thereof. The preparation method comprises the following steps: weighing the raw materials in parts by weight: 5-8 parts of graphene, 15-35 parts of a fluorine-containing polymers, 5-8 parts of tungsten disulfide, 12-15 parts of a bronze powder, 35-40 parts of a solvent, 1-5 parts of a solubilizer, 1-3 parts of a dispersing auxiliary agent and 5-10 parts of a rheological auxiliary agent; uniformly mixing the fluorine-containing polymer, tungsten disulfide, a bronze power and a solubilizer and dispersing auxiliary agent uniformly; then grinding the mixture by a sand mill to obtain a first mixture; uniformly mixing the rheological auxiliary agent with the residual solvent and leaving the mixture to stand to obtain a second mixture; and uniformly mixing the first mixture, the second mixture and graphene, mixing the mixture, cooling and crushing the mixture, filtering, discharging and packaging the mixture. The graphene self-lubricating wear-resistant corrosion-resistant scale-inhibiting wax coating agent has excellent characteristics of high-low temperature resistance, chemical stability, non viscidity, low friction coefficient and the like, and the economical benefit of an enterprise is increased greatly.

Description

technical field [0001] The invention belongs to the technical field of pipeline anti-corrosion coating agents, and relates to a graphene self-lubricating, wear-resistant, anti-corrosion and anti-scaling wax coating agent and a preparation method thereof. Background technique [0002] With the rapid development of the world's oil and gas industry, the hazards of corrosion in oil and gas fields are becoming more and more obvious. Corrosion not only causes direct economic losses such as oil and gas structure damage and crude oil leakage, but also causes catastrophic accidents such as fire and explosion, as well as serious consequences such as environmental pollution and shutdown. It has greatly affected the safe production and economic benefits of the oil and gas industry. The anti-corrosion work of oil pipelines refers to reducing the corrosion speed of pipelines to the maximum extent possible and prolonging the life of pipelines. That is, there are no general anti-corrosion m...
