Abstract
The invention discloses a kind of preparation method of efficient short oil-ity alcohol acid resin corrosive enamel; using dryness short oil-ity alcohol acid resin and the β acyl groups camptothecine of 20 (s) O, 3 β acetoxyl groups, 5 androstene 17 as film forming matter; using ortho-xylene as solvent; the manganese salt of the polyether-modified Dimethicone Copolyol body of talcum powder, bentonite, dispersant polyethylene glycol 200, levelling agent and drier aphthenic acids is added, high-speed stirred produces efficient short oil-ity alcohol acid resin corrosive enamel.The enamel paint has higher decay resistance and ageing-resistant performance, can be applied to the heavy antisepsis engineering in the fields such as petrochemical equipment, pipeline, offshore oil platform, terminal facilities, ship.
Description
Technical field
The present invention relates to enamel paint field, more particularly, to a kind of preparation side of efficient short oil-ity alcohol acid resin corrosive enamel
Method.
Background technology
Because the equipment such as petrochemical equipment, pipeline, offshore oil platform, ship are corroded by atmospheric environment, particularly ship
Oceangoing ship equipment underwater position is because easily ftracture in the corrosive mediums such as long period of soaking sodium chloride by foaming, the method handled at present
It is to add the heavy metal compounds such as substantial amounts of lead orthoplumbate in paint formulation, but this kind of corrosion-inhibiting coating constantly has these heavy
Metallic lead plasma separates out, and serious Marine Pollution, river and soil environment, serious shadow is caused to global ecological environment and human body
Ring.But due to currently without suitable substitute technology, therefore, it is significant to find suitable substitute technology.
Alkyd resin is formed by polyalcohol, phthalic anhydride and aliphatic acid or oil (fatty acid triglyceride) condensation polymerization
Oil modified polyester resin.Many hydrogen bonds in alkyd resin macromolecular be present, intermolecular force is big, can be with many compounds
Crosslinking film forming is carried out, so having using alkyd resin as the alkyd resin antifouling paint that film forming matter is made into preferably corrosion-resistant
Property, the characteristic such as permeability resistance, wearability and preferable adhesive force, it is but many with the variable factor of alkyd resin crosslinking film forming,
At present because the monomer of selection matches with alkyd resin incorrect, the rigidity of crosslinking is also poor, and therefore, decay resistance is not very
Height, it can not meet the needs of actual adverse circumstances.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of simple, easy to manufacture, a kind of efficient short oil alcohol of equipment
The preparation method of acid resin corrosive enamel.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：With dryness short oil-ity alcohol acid resin and 20
(s)-O-3 beta-acetoxyl group-5s-the β of androstene-17-acyl group camptothecine is film forming matter, using ortho-xylene as solvent, adds cunning
The polyether-modified Dimethicone Copolyol body of stone flour, bentonite, dispersant polyethylene glycol 200, levelling agent and drier cycloalkanes
It is prepared by the manganese salt of acid.
A kind of preparation method of above-mentioned efficient short oil-ity alcohol acid resin corrosive enamel, with dryness short oil-ity alcohol acid resin and
20 (the s)-O-3 beta-acetoxyl group-5s-β of androstene-17-acyl group camptothecine is film forming matter, using ortho-xylene as solvent, is added
The polyether-modified Dimethicone Copolyol body of talcum powder, bentonite, dispersant polyethylene glycol 200, levelling agent and drier ring
The manganese salt of alkanoic acid, stir and produce in retort high speed.
A kind of preparation method of above-mentioned efficient short oil-ity alcohol acid resin corrosive enamel, including procedure below：
By the dryness short oil-ity alcohol acid resin of 10~30 parts by weight, 20 (s)-O-3 beta-acetoxyl group-5s-hero of 15~30 parts by weight
- 17 β of steroid alkene-acyl group camptothecine and the ortho-xylene solvent of 40~60 parts by weight are together added in retort and stirred, followed by
Continue the talcum powder of 5~20 parts by weight, the bentonite of 5~15 parts by weight, the dispersant polyethylene glycol 200 of 1~10 parts by weight, 1
The manganese salt of the polyether-modified Dimethicone Copolyol body of levelling agent of~8 parts by weight, the drier aphthenic acids of 1~6 parts by weight
Together put the stirring of retort high speed into and produce within 1 hour a kind of efficient short oil-ity alcohol acid resin corrosive enamel.
Experiment is found, with dryness short oil-ity alcohol acid resin and 20 (the s)-O-3 beta-acetoxyl group-5s-β of androstene-17-acyl group
Camptothecine is film forming matter, using ortho-xylene as solvent, adds talcum powder, bentonite, dispersant polyethylene glycol 200, levelling
Short oil-ity alcohol acid resin anti-corrosion magnetic prepared by the manganese salt of the polyether-modified Dimethicone Copolyol body of agent and drier aphthenic acids
Paint, be sprayed in tinplate sheet, test when being soaked 100 hours in 3.5% sodium chloride solution it is non-foaming, do not ftracture, do not take off
Fall；Tested on electrochemical operation, bare area is 1 square centimeter, and AC impedance is in 500 k Ω .cm2Left and right, therefore, system
Standby short oil-ity alcohol acid resin corrosive enamel has higher Corrosion Protection, more than current short oil-ity alcohol acid resin anti-corrosion magnetic
Paint, and equipment is simple, it is easy to make.
Brief description of the drawings
Fig. 1 is a kind of AC impedance figure of efficient short oil-ity alcohol acid resin corrosive enamel in embodiment 1.
Embodiment
Embodiment 1
