Description
Technical field
The invention belongs to oil field technical field of coatings, more particularly to a kind of oil well pipe nanometer heavy antisepsis Wear-resistant, high-temperature resistant powder
Last coating.
Background technology
At present, China's major part oil well exploration exploitation has entered the middle and later periods, with deeply developing for oil field, production of recovering the oil
In, it is quite serious to oil well pipe corrosion as a result of the substantial amounts of chemical assistant displacement of reservoir oil, along with wax deposition fouling, more some oil
Well generates very big eccentric wear phenomenon, and what is had even rubs sucker rod, is brought greatly to oil field production and economic benefit
Loss.
The content of the invention
In order to solve technical problem present in background technology, it is wear-resisting resistance to that the present invention provides a kind of oil well pipe nanometer heavy antisepsis
High temperature powder coating, the present invention has anti-eccentric wear, anticorrosion, high temperature resistant feature, while there is extraordinary energy-saving effect.
Technical problem solved by the invention is realized using following technical scheme：The oil well pipe nanometer wear-resisting resistance to height of heavy antisepsis
Warm powdery paints is obtained by following raw materials, and each raw material are by weight ratio：70~80 parts of epoxy resin；Acrylic resin 30
~40 parts；The agent of acrylate stream is flat 0~10 part；0.5~1.5 part of polynary organic phenols curing agent；10~15 parts of talcum powder；Rest in peace
It is fragrant 0.04 part~0.08 part；0.05~0.07 part of imidazoles；1.5~2.5 parts of carbon black；3~5 parts of vegetable oil；Graphene and corundum
15~25 parts, the wherein mass ratio of Graphene and corundum is 1：1, the mesh of granularity 240 of powdery paints.
Each raw material are by weight ratio in such scheme：75 parts of epoxy resin；35 parts of acrylic resin；Acrylate stream
Agent is flat 5 parts；1 part of polynary organic phenols curing agent；15 parts of talcum powder；0.05 part of styrax；0.05 part of imidazoles；2 parts of carbon black；Plant
4 parts of oil；20 parts of Graphene and corundum, the wherein mass ratio of Graphene and corundum are 1：1, the mesh of granularity 240 of powdery paints.
The preparation method of oil well pipe nanometer heavy antisepsis Wear-resistant, high-temperature resistant powdery paints：First, by all each components by proportioning
Reactor is added, mixing is stirred, after 30~50 minutes stir, carries out being heated to 130 degree of compressing tablets, pressure is
300Kg is suppressed, and after compression molding, being ground by steel carries out pulverization process, and the granularity of powdery paints reaches 240 mesh, then carries out again
Grinding sub-sieve, is obtained nanometer heavy antisepsis Wear-resistant, high-temperature resistant powdery paints.
The film forming matter of oil well pipe nanometer heavy antisepsis Wear-resistant, high-temperature resistant powdery paints is with epoxy resin and acrylic resin
Based on because epoxy bond in epoxy resin can chemically react with metallic bond combining, there is good adhesive force, epoxy resin with
Synergy after acrylic resin combination, there is very strong corrosion resistance to soda acid, therefore anti-Corrosion Protection is very good, salt
Very serious to corrosion of metal because sodium chloride its aqueous solution exists in the form of an ion, i.e., with sodium ion and
Chlorion is present, and corrosive nature is very strong, but epoxy resin and acrylic resin articulated system, not only have very strong adhesive force,
Also very strong anti acid alkali performance, this is that its material nature is determined, oil well pipe nanometer heavy antisepsis Wear-resistant, high-temperature resistant powder
Nanoscale graphite alkene is introduced in coating, the tensile strength for making coating is 200 times of iron, organic matter epoxy resin and inorganic matter gold
The combination of steel sand, Graphene, causes soft with hard combination, adds the tensile strength of Graphene, makes medium and oil well
There is one layer to be effectively protected film between pipe, film is not only wear-resistant to go back high temperature resistance (general medium temperature is within 80 degree), nanometer
Level Graphene is a kind of superconductor, and the excess charges in electrolyte are sent to releasable periphery by nanoscale graphite alkene, and
Resistivity is zero, and reach does not carry out electron exchange with iron, so as to protect oil well pipe.
In coating plus vegetable oil after reached lubrication, the smooth lubrication of coating surface, self-lubricating property is very good, wax without
The choice specimen of calligraphy is enclosed, and the bacterium contact of dirt will be killed, and cannot also tie on tube wall, so powder coating has good antiscale
Wax control is acted on, and has reached the purpose of antibacterial, due to adding the mineral matters such as diamond dust in powdery paints, has coating certain
Heat-blocking action, can delay the loss of temperature, also function to the effect of wax control.
Oil well pipe nanometer heavy antisepsis Heat Resistant Powder Coatings, in order to solve anti-eccentric wear oil well pipe research and development, because powder
High abrasion resin and wear resistant filler Graphene and corundum are introduced in powder formulation, powder is possessed the ability for bearing friction high,
Coefficient of friction is very small, and drag reduction is also very good, due to coating self lubricity in itself, possesses very strong energy-saving effect.
Beneficial effects of the present invention are：The application by productive experiment find, due to the coefficient of friction of itself very
Small, equivalent to phase mutual friction between ice and ice, fractional energy savings reaches more than 90%.Because oil well inside pipe wall is prevented with this product
Corruption treatment, the operation well workover time, by original 90 days, improves more than 365 days till now, and oil well operation is very normal, drop
Low energy consumption, improves yield.More than 1 year, oil well pipe are with the oil well pipe effective life of the product preservative treatment
Excellent through inspection, surfacing is smooth, without any corrosion and scaling phenomenon, has saved every cost, and also extending equipment makes
With the cycle, good overall economic efficiency is have received, be each oil pipeline eccentric abrasion prevention, anti-heavy corrosion, high temperature resistant economical efficiency wound
Good start is made.
Specific embodiment
The present invention is described further below in conjunction with experiment：
The preparation of oil well pipe nanometer heavy antisepsis Wear-resistant, high-temperature resistant powdery paints：First by epoxy resin 75Kg, acrylic acid tree
