Description
Technical field
The present invention relates to enamel paint fields, more particularly, to a kind of abietyl short oil-ity alcohol acid resin anti-corrosion of high pitting potential
The preparation method of enamel paint.
Background technique
Corrosion due to equipment such as petrochemical equipment, pipeline, offshore oil platform, ships by atmospheric environment, especially ship
Oceangoing ship equipment underwater position due to easily risen in the corrosive mediums such as long period of soaking sodium chloride spot corrosion, blistering, crack, fall off it is existing
As.The method handled at present is to add the heavy metal compounds such as a large amount of lead orthoplumbate in paint formulation, however this kind of anti-corrosion
Coating constantly has the precipitation of these heavy metal lead plasmas, and serious Marine Pollution, river and soil environment give global ecological environment
And human body causes to seriously affect.But due to currently without suitable substitute technology, finding suitable substitute technology has
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, and therefore, pitting resistance is not high, meets
The not 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 pine of high pitting potential
The preparation method of perfume base short oil-ity alcohol acid resin corrosive enamel.
In order to solve the above technical problems, the present invention adopts the following technical scheme: with stemness short oil-ity alcohol acid resin and propylene
Pimaric acid (ethylenediamine) amide adds the poly- second of talcum powder, bentonite, dispersing agent using ortho-xylene as solvent for film forming matter
The polyether-modified Dimethicone Copolyol body of glycol 200, levelling agent and the preparation of drier aphthenic acids molysite.
The preparation method of the abietyl short oil-ity alcohol acid resin corrosive enamel of above-mentioned a kind of high pitting potential, with stemness short oil
Spending alkyd resin and rosin acrylic acid (ethylenediamine) amide is film forming matter, using ortho-xylene as solvent, adds talcum powder, swollen
Moisten 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 short oil-ity alcohol acid resin corrosive enamel of above-mentioned high pitting potential, including following mistake
Journey:
By the stemness short oil-ity alcohol acid resin of 20~50 parts by weight, 0.5~5 parts by weight rosin acrylic acid (ethylenediamine) amide and
The ortho-xylene solvent of 40~60 parts by weight is added in reactor tank together to stir evenly, and is further continued for the talcum of 5~20 parts by weight
Powder, the bentonite of 5~15 parts by weight, the dispersing agent polyethylene glycol 200 of 1~10 parts by weight, 1~8 parts by weight levelling agent polyethers
Modified dimethyl polysiloxane copolymer, 1~6 parts by weight drier aphthenic acids molysite put into together reactor tank high speed stirring
A kind of 1 hour abietyl short oil-ity alcohol acid resin corrosive enamel up to high pitting potential.
Experiment discovery, using stemness short oil-ity alcohol acid resin and rosin acrylic acid (ethylenediamine) amide as film forming matter, with neighbour
Dimethylbenzene is solvent, adds talcum powder, bentonite, dispersing agent polyethylene glycol 200, the polyether-modified polydimethylsiloxanes of levelling agent
Alkane copolymer and drier aphthenic acids molysite prepare abietyl short oil-ity alcohol acid resin corrosive enamel, are applied to 6063 aluminum alloy sheets
On, using testing on electrochemical operation, bare area is 1 square centimeter, and pitting potential improves nearly 100 mV；In addition, should
Enamel paint is sprayed on 6063 aluminum alloy sheets, and experiment there is not spot corrosion when impregnating 100 hours in 3.5% sodium chloride solution, is not also risen
Bubble does not crack, does not fall off.Therefore, the abietyl medium oil alkyd corrosive enamel corrosion resistance with higher of preparation,
And other antiseptic properties are also more excellent, and more than current short oil-ity alcohol acid resin corrosive enamel, and equipment is simple, production is held
Easily.
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 medium oil alkyd corrosive enamel and the short oil-ity alcohol acid resin 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 short oil-ity alcohol acid resin of 25 parts by weight, rosin acrylic acid (ethylenediamine) amide of 2 parts by weight and 50 parts by weight
Ortho-xylene solvent be added in reactor tank stir evenly together, be further continued for by the talcum powder of 15 parts by weight, 15 parts by weight it is swollen
Moisten soil, the polyether-modified Dimethicone Copolyol body of levelling agent of the dispersing agent polyethylene glycol 200 of 2 parts by weight, 2 parts by weight, 1
The reactor tank high speed that the drier aphthenic acids molysite of parts by weight is added together stirs 1 hour up to (ethylenediamine) containing rosin acrylic acid
Amide corrosive enamel；Another corrosive enamel is not other than adding rosin acrylic acid (ethylenediamine) amide of 2 parts by weight, other operations
Process is identical to get without rosin acrylic acid (ethylenediamine) amide corrosive enamel.
Three, the antiseptic property test of medium oil alkyd corrosive enamel
<1>use solvent volume than for the dimethylbenzene of 3:2 and acetic acid fourth two parts of short oil-ity alcohol acid resin corrosive enamels of preparation
Ester mixed solvent dilution, then take 18 μ L corrosive enamels to be applied on two piece of 6063 spare aluminum alloy sheet respectively, film it is exposed
Area is 1 square centimeter, dries 24 hours in air, activation polarization is then carried out in 3.5% sodium chloride solution
Curve test, compares pitting potential, and discovery has added the short oil-ity alcohol acid resin corrosive enamel of rosin acrylic acid (ethylenediamine) amide
Pitting potential improve nearly 100 mV;In addition, having added the corruption of the alkyd resin corrosive enamel of rosin acrylic acid (ethylenediamine) amide
Erosion electric current is significantly reduced.
<2>contain preparation uses solvent volume than for 3:2's with without rosin acrylic acid (ethylenediamine) amide corrosive enamel
Dimethylbenzene and n-butyl acetate mixed solvent dilution, are then sprayed on 6063 spare aluminum alloy sheets, are soaked in after 24 hours
It in 3.5% sodium chloride solution, impregnates 100 hours, is risen containing rosin acrylic acid (ethylenediamine) amide corrosive enamel without spot corrosion, nothing
Bubble, without cracking, without obscission;Without rosin acrylic acid (ethylenediamine) amide corrosive enamel occur serious spot corrosion, blistering,
Cracking, obscission.
Therefore, abietyl short oil-ity alcohol acid resin corrosive enamel prepared by the present invention anti-pitting corrosion with higher and its
Its antiseptic property.
