Description
Technical field
The present invention relates to enamel paint fields, more particularly, to a kind of high pitting potential (Pitting corrosion
Potential the preparation method of abietyl long oil alkyd corrosive enamel).
Background technique
Due to the metal materials equipment such as petrochemical equipment, pipeline, offshore oil platform, ship, since pitting potential is lower, pole
Vulnerable to the corrosion of atmospheric environment, especially ship equipment underwater position due to corrosive mediums such as long period of soaking sodium chloride
In easily cause spot corrosion, blistering, cracking, obscission.The method handled at present is to add a large amount of four oxidation in paint formulation
The heavy metal compounds such as three lead, however this kind of corrosion-inhibiting coating constantly has the precipitation of these heavy metal lead plasmas, serious pollution sea
Ocean, river and soil environment, cause to seriously affect to global ecological environment and human body.But due to currently without suitable substitution
Therefore technology finds suitable substitute technology and is of great significance.
Alkyd resin is formed by polyalcohol, phthalic anhydride and fatty acid or oil (fatty acid triglyceride) condensation polymerization
Oil modified polyester resin.There are many hydrogen bonds in alkyd resin macromolecular, intermolecular force is big, can be with many compounds
Crosslinking film forming is carried out, so having using the alkyd resin antifouling paint that alkyd resin is made into as film forming matter preferable corrosion-resistant
Property, the characteristics such as permeability resistance, wearability and preferable adhesive force, but it is many with the variable factor of alkyd resin crosslinking film forming,
Matched at present due to the monomer of selection with alkyd resin inappropriate, pitting potential is lower, therefore, pitting resistance be not it is very high,
It can not meet the needs of practical adverse circumstances.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of equipment simply, manufacture is easy, a kind of high pitting potential
The preparation method of the abietyl long oil alkyd corrosive enamel of (Pitting corrosion potential).
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: with stemness long oil alkyd and third
Alkene pimaric acid (ethylenediamine) amide adds the poly- second of talcum powder, bentonite, dispersing agent using isobutanol as solvent for film forming matter
The preparation of the manganese salt of the polyether-modified Dimethicone Copolyol body of glycol 200, levelling agent and drier aphthenic acids.
The preparation method of the abietyl long oil alkyd corrosive enamel of above-mentioned a kind of high pitting potential, with stemness long oil
It spends alkyd resin and rosin acrylic acid (ethylenediamine) amide and adds talcum powder, swelling using isobutanol as solvent for film forming matter
Soil, dispersing agent polyethylene glycol 200, the polyether-modified Dimethicone Copolyol body of levelling agent and drier aphthenic acids molysite,
It is stirred in reactor tank high speed to obtain the final product.
A kind of preparation method of the abietyl long oil alkyd corrosive enamel of above-mentioned high pitting potential, including following mistake
Journey:
By the stemness long oil alkyd of 20~50 parts by weight, 0.5~5 parts by weight rosin acrylic acid (ethylenediamine) amide and
The iso-butanol solvent of 20~40 parts by weight is added in reactor tank together to stir evenly, be further continued for by the talcum powder of 5~20 parts by weight,
The bentonite of 5~15 parts by weight, the dispersing agent polyethylene glycol 200 of 1~10 parts by weight, the levelling agent of 1~8 parts by weight are polyether-modified
Dimethicone Copolyol body, 0.5~5 parts by weight drier aphthenic acids molysite put into together reactor tank high speed stirring
1 hour to obtain the final product；
Experiment discovery, using stemness long oil alkyd and rosin acrylic acid (ethylenediamine) amide as film forming matter, with isobutanol
For solvent, talcum powder, bentonite, dispersing agent polyethylene glycol 200, the polyether-modified Dimethicone Copolyol of levelling agent are added
The abietyl long oil alkyd corrosive enamel of the molysite of body and drier aphthenic acids preparation, is applied on 6063 aluminum alloy sheets,
Using testing on electrochemical operation, bare area is 1 square centimeter, and pitting potential improves nearly 100 mV；In addition, by the enamel paint
It is sprayed on 6063 aluminum alloy sheets, experiment there is not spot corrosion when impregnating 100 hours in 3.5% sodium chloride solution, not blistering, no yet
It cracks, fall off.Therefore, the abietyl long oil alkyd corrosive enamel corrosion resistance with higher of preparation, and
Other antiseptic properties are also more excellent, and more than current long oil alkyd corrosive enamel, and equipment is simple, is easy to make.
Detailed description of the invention
Fig. 1 is a kind of Abietyl-containing third of high pitting potential (Pitting corrosion potential) in embodiment 1
Alkene pimaric acid (ethylenediamine) amide long oil alkyd corrosive enamel and the long oil alkyd corrosive enamel for being free of rosin
Polarization curve.
Specific embodiment
Embodiment 1
One, the processing of 6063 aluminum alloy sheets
6063 aluminum alloy sheets are successively polished with the alumina powder of 1.0 μm, 0.3 μm on polishing cloth, are then placed in 5% salt
5 min of ultrasound, place into deionized water and are cleaned by ultrasonic 5 min in acid, are finally putting into dehydrated alcohol and dry after 6 min of ultrasound
It is spare.
Two, the preparation for containing and being free of rosin acrylic acid (ethylenediamine) amide corrosive enamel
By the stemness long oil alkyd of 25 parts by weight, rosin acrylic acid (ethylenediamine) amide of 2 parts by weight and 20 parts by weight
Iso-butanol solvent be added in reactor tank stir evenly together, be further continued for the swelling of the talcum powder of 15 parts by weight, 10 parts by weight
The polyether-modified Dimethicone Copolyol body of levelling agent, 1 weight of soil, the dispersing agent polyethylene glycol 200 of 2 parts by weight, 2 parts by weight
Reactor tank high speed is added together and stirs the 1 hour rosin up to a high pitting potential for the molysite for measuring the drier aphthenic acids of part
Base long oil alkyd corrosive enamel；Rosin acrylic acid (ethylenediamine) acyl of another corrosive enamel in addition to not adding 2 parts by weight
Outside amine, other operating process are identical.
Three, the antiseptic property test of long oil alkyd corrosive enamel
<1>use solvent volume than diluting for the isopropanol of 2:3 and isobutanol mixed solvent two parts of corrosive enamels of preparation,
Then 18 μ L corrosive enamels are taken to be applied on two piece of 6063 spare aluminum alloy sheet respectively, the bare area of film is 1 square li
Rice is dried 24 hours in air, electrochemical tests test, comparison point is then carried out in 3.5% sodium chloride solution
Current potential is lost, it is close that discovery has added the pitting potential of the long oil alkyd corrosive enamel of rosin acrylic acid (ethylenediamine) amide to improve
100 mV;In addition, the corrosion current of the long oil alkyd corrosive enamel of rosin acrylic acid (ethylenediamine) amide has been added also to show
Work reduces.
<2>contain preparation uses solvent volume than for 2:3's with without rosin acrylic acid (ethylenediamine) amide corrosive enamel
Isopropanol and the dilution of isobutanol mixed solvent, are then sprayed on 6063 spare aluminum alloy sheets, are soaked in 3.5% after 24 hours
Sodium chloride solution in, impregnate 100 hours, containing rosin acrylic acid (ethylenediamine) amide corrosive enamel without spot corrosion, without blistering, without opening
It splits, without obscission;Serious spot corrosion occurs without rosin acrylic acid (ethylenediamine) amide corrosive enamel, blistering, cracking, takes off
Fall phenomenon.
Therefore, abietyl long oil alkyd corrosive enamel prepared by the present invention corrosion resistance with higher and anti-
Corrosive nature.
