Titanium and nano fluorine-containing poly (aryl ether ketone) copolymer, coating made thereof and manufacturing method thereof

Abstract

The invention makes further technical innovation in the prior invention and obtains a titanium and nano fluorine-containing poly (aryl ether ketone) macromolecular alloy copolymer by copolymerizationof a nano organic titanium polymer and a nano alumina-modified fluorine-containing poly (aryl ether ketone) polymer. The novel material has a series of excellent physicochemical characteristics and isextremely suitable to meet the special protection requirements of exploitation equipment of underground deep crude oil and natural gas such as high hardness, corrosion resistance, high temperature resistance, high-pressure hot vapor penetrability resistance, dirt picking up and scale deposition prevention, aging resistance, durability and other properties. A nano organic titanium macromolecular alloy coating manufactured by using the novel chemical material of the invention as a substrate film forming material resin is used in anticorrosion coatings of oil-gas field well exploitation drillingtools and well pipes and has the advantages of prolonging the protection life of a nano ceramic film coating and an organic titanium special anticorrosion coating by several times, greatly reducing oil and natural gas exploitation cost and equipment maintenance cost and obviously improving comparable relative production efficiency compared with the product of the prior invention.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis and chemical composition, and relates to a nano-organic titanium fluorine-containing polyaryl ether ketone copolymer and a nano-organic titanium polymer alloy coating; it is mainly used in deep well drilling tools and oil production pipelines in oil and gas fields at high temperatures. Special anti-corrosion coating protection with special technical requirements under high-pressure corrosive environment conditions. Background technique [0002] The exploitation of deep underground crude oil or natural gas requires complex geological conditions and corrosive environments (as shown in Table 1). Due to the strong penetration of hot steam at high temperature (80-250°C) and high pressure (>3MPa), coupled with various corrosive media in crude oil and sewage (such as SO 4 2- , NO 3 - , Cl - , F - 、CN - 、Ba + , Ca + etc.) and the erosion of harmful bacteria, which accelerates the ch...
