Description
Technical field
The present invention relates to coating preparation fields, and in particular to the environmentally friendly transparent anti-corrosion Wax deposition resistant coating of one kind and coating
Preparation method.
Background technique
In early days, it is believed that anticorrosion with coat mainly forms shielded layer in metal surface, metal surface and oxygen gas and water are prevented
It is in contact.Later, lot of research surface, due to the access that the microdefect or hydrophilic radical of coating are formed, so that applying
Layer has certain ventilative and seepage of water, therefore water needed for corrosion and the oxygen of dissolution can also be obtained from coating
, coating can not shield completely corrosive medium.After the corrosion-inhibiting pigment of passivation type is added in coating, there can be water to deposit
In case, the ion containing corrosion inhibition is dissociated, fine and close passivation layer is formed, is attached to metal base surface, thus
Inhibit the generation further corroded.When corrode point existing for oxygen concentration reach certain value when, electrochemical reaction can be produced
Raw Fe2+It is oxidized to Fe3+, then with OH-In conjunction with rear generation iron hydroxide, it is deposited on and passivation layer, suppression is formed by protection matrix surface
The further occurrence of corrosion reaction processed, this process are exactly typical passivation.It is right when the pH value of metal surface is in alkalinity
Passivation reaction is advantageous, when pH value is lower than 10, to reach the less susceptible satisfaction of oxygen concentration required for passivation, therefore applying
A certain amount of oxidant is added in material as corrosion-inhibiting pigment, such as used plumbite, chromate all the time, is all benefit
The protection to metal is realized with passivation inhibition principle.
As described above, most common kind has red lead, lead powder and various chromate in traditional corrosion-inhibiting pigment, they are general
Contain the poisoning metal elements such as lead, chromium and cadmium.Although this kind of corrosion-inhibiting pigment shows good Corrosion Protection in use,
But in the production and use process, these poisonous and hazardous elements can endanger environment, endanger human health, many countries have prohibited
Only use.European Union " electrically, uses the finger of certain harmful substances in implementation ROHS instruction on July 1st, 2006 in electrical equipment
Enable ", it exports in the electronic electric equipment of European Union, is forbidden to use or contains six kinds of harmful substances, wherein just including Cr VI.
People begin to use more environmentally friendly novel anticorrosion pigment to replace traditional corrosion-inhibiting pigment, are passivated corrosion inhibition type
Corrosion-inhibiting pigment is the corrosion-inhibiting pigment being most widely used, and phosphate, molybdate, borate etc. all originate from this kind.Wherein
It is the environmentally friendly anti-corrosion paint being most widely used by the phosphate of representative of trbasic zinc phosphate, is used till today from nineteen sixty-five, extensively
It is general for oiliness, in watery anti-corrosion paint.The anticorrosion mechanism of phosphoric acid zinc pigment is complex, mainly in the first of corrosion
Phase generates local cathode and anode in metal surface, makes the molysite of dissolution and ferrous ion that hydrolysis occur and release proton, with
Zinc orthophosphate reacts, and ultimately generates insoluble ferrous phosphate, to form Fe-Zn-P2O5Fine and close passivating film.It is phosphate-based
The corrosion-inhibiting pigment of column, also comprising polymer phosphate aluminium, calcium phosphate etc., the results show they have remarkably in anticorrosion field
Performance.
Trbasic zinc phosphate is component part important in non-poisonous antirust pigment.Due to larger (the 15-45 μ of the particle of common trbasic zinc phosphate
M), shape is in brick, and surface area is smaller, bad dispersibility, and the level of traditional zinc yellow is not achieved in rustless property, it is difficult to Quan Mianqu
For traditional harmful rust resisting pigment.For these reasons, researcher has carried out relevant modified work to common trbasic zinc phosphate, changes
Sex work mainly includes two aspects: (1) physical modification, including physical property modifications such as shape, partial sizes to phosphoric acid zinc particles.
(2) chemical modification, including the compound of metal, the modification of the chemical aspects such as surface preparation.By with the metals such as aluminium, molybdenum, calcium, iron
Phosphoric acid zinc pigment obtained from composite modified is referred to as second generation phosphate rust resisting pigment.Either still changed by physical modification
It learns and is modified, be finally in the electrochemical anti-corrosive performance for improving pigment, the compatibility of pigment and paint film, the shielding of paint film is made
With the improvement of adhesive force of paint film and substrate etc..
Further investigation to polymer chemistry and synthetic resin provides excellent film forming matter for anticorrosive coating.By
In special chemical structure, the characteristics of organic siliconresin has organic material and inorganic material concurrently.Organic siliconresin finally processes system
The performance of product depends on the ratio between organic in its structure and inorganic part, the i.e. value of R/Si.Organic siliconresin with practical value,
The ratio of R and Si is between 1.0-1.6 in molecular composition.Universal law is that R/Si value is smaller, and obtained organic siliconresin is just
It can more solidify at a lower temperature；And the value of R/Si is bigger, obtained organic siliconresin to make it be fully cured needs exist
It is toasted for a long time at a high temperature of 200-250 DEG C, resulting hardness of paint film is poor, but thermoelasticity is more much better than the former.
Organic siliconresin is a kind of thermosetting plastics, his performance most outstanding first is that excellent thermo oxidative stability,
Heat resistance is much better than common organic resin.Organic siliconresin has very high thermal decomposition temperature, can make for a long time at 200-250 DEG C
With without decomposing, and the short time is also resistant to 350-500 DEG C of high temperature.Higher temperature is then resistant to after heat-resistant filler is added.Modification has
The heat resistance of machine silicone resin is poorer than pure organic siliconresin, but better than organic resin, be typically in the range of organic siliconresin with it is corresponding
Between organic resin.The feature of another protrusion of organic siliconresin is excellent electrical insulation capability, and it can be in very wide temperature
With this performance is kept in frequency range.The electric breakdown strength of general organic siliconresin is 50kv/mm, and volume resistivity is
1013-1015 Ω cm, dielectric constant are about 3, and dielectric loss angle tangent value is in 10-3 or so.In addition, organic siliconresin also has
There are brilliant moisture resistance, waterproof, antirust, cold-resistant, resistance to ozone and weather resistance, to most aqueous for example dilute mineral of chemical reagent
The corrosion resistance of acid is good.Organic siliconresin has very high hydrophobicity, therefore the water imbibition of its film is small.Even if absorbing
Moisture can also volatilize rapidly and be restored to original state, and then electrical characteristic substantially reduces general organic resin after immersion, inhale
The moisture difficulty or ease of receipts are removed.The weatherability of organic siliconresin is also quite excellent, due to that will not generate by UV-induced freedom
Base reaction, is also not easy to be oxidized, therefore excellent in weather.And general organic resin is other than acrylic resin, good weatherability
Organic resin it is few.
There are mainly four types of the mechanism of crude oil wax, comprising: molecule diffusion mechanism, Blang's diffusion mechanism, gravitational settling mechanism
With shearing disperse mechanism.Wherein molecule diffusion mechanism is the most important mechanism of crude oil wax.In the duct crude oil be usually with
The mode of laminar flow flows, and when crude oil temperature decline, will appear temperature gradient in laminar flow.If temperature is lower than the temperature that wax partial crystallization goes out
Degree, wax molecule are precipitated are blended among liquid crude oil in solid form, and liquid crude oil at this time is the saturated solution of wax crystalline substance.Due to leaning on
Closely there are temperature gradients for the crude oil of inner wall of the pipe and the crude oil at oil stream center, and this generates the concentration of two region soluble wax crystalline substances
Gradient.Oil stream central temperature is high, and the concentration of dissolving wax crystalline substance is high, and the crude oil temperature close to inner wall of the pipe is low, dissolving wax crystalline substance it is dense
Spend low, according to diffusion principle, the wax crystalline substance at oil stream center can be spread to inner wall of the pipe direction, and the lower temperature of inner wall of the pipe is just led
The precipitation and deposition of wax molecule are caused.
Crude oil acquisition transport is a complicated system, and the wax deposition phenomenon of oil pipeline is in addition to by crude oil temperature, this is important
Factor influence it is outer, the factors such as the tube wall temperature difference, water content in crude oil and flow velocity, pipe surface property to the wax deposition of oil pipeline also have compared with
Big influence.The surface free energy of oil pipeline inner wall plays absolute effect to the adherency of wax and colloid, and wax crystalline substance is in adsorption capacity
Under effect, it is adhered to oil pipeline inner wall surface, and constantly deposit, this adsorption capacity size depends on the surface of tube wall and wax crystalline substance
Wetability.The wetability of body surface and hydrophobic, oleophobic property changes with the difference of its surface coating layer property, as long as
One layer of coat is formed on body surface, so that it may so that these properties on surface generate variation.The present invention from change oil pipeline
From the point of view of surface wettability, in one layer of oil pipeline coated inner wall wear-resisting anti-sticking coat, to change the table of inner wall of the pipe
Face characteristic makes to form oleophobic surface in nonwetting state between institute transporting fluid and inner wall of the pipe, viscous with wax intergranular to reduce
It is attached, prevent the deposition from the wax being precipitated in crude oil in inner wall of the pipe.In addition, coat also reduce inner wall of the pipe and crude oil it
Between interaction force, make to flow crude oil and form partial slip in tube wall surface, so as to be substantially reduced on-way resistance, save length
Oil transportation energy consumption apart from oil pipeline.
