Abstract
The invention discloses a kind of preparation method of efficient alkyd resin corrosive enamel, using dryness long oil alkyd, dryness short oil-ity alcohol acid resin and the β acyl groups camptothecine of 20 (s) O androstane-14s alkene 17 as film forming matter, using volume ratio as 5:2 paraxylene and butyl acetate mixture is 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 alkyd 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 method of efficient alkyd resin corrosive enamel.
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 chemical combination
Thing carries out crosslinking film forming, so having using alkyd resin as the alkyd resin antifouling paint that film forming matter is made into preferably resistance to
The characteristics such as corrosivity, permeability resistance, wearability and preferable adhesive force, but with alkyd resin crosslinking film forming variable factor
A lot, at present because the monomer of selection matches with alkyd resin incorrect, the rigidity of crosslinking is also poor, and therefore, corrosion resistance is not
It is very high, 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 alkyd resin of equipment
The preparation method of corrosive enamel.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：It is short with dryness long oil alkyd, dryness
Oil content alkyd resin and 20-17 β of (s)-O- androstane-4- alkene-acyl group camptothecine are film forming matter, with paraxylene and butyl acetate
Mixture be solvent, add the polyether-modified poly dimethyl silicon of talcum powder, bentonite, dispersant polyethylene glycol 200, levelling agent
It is prepared by the manganese salt of oxygen alkane EVA and drier aphthenic acids.
A kind of preparation method of above-mentioned efficient alkyd resin corrosive enamel, it is short with dryness long oil alkyd, dryness
Oil content alkyd resin and 20-17 β of (s)-O- androstane-4- alkene-acyl group camptothecine are film forming matter, with paraxylene and butyl acetate
Mixture be solvent, add the polyether-modified poly dimethyl silicon of talcum powder, bentonite, dispersant polyethylene glycol 200, levelling agent
The manganese salt of oxygen alkane EVA and drier aphthenic acids, stir and produce in retort high speed.
A kind of preparation method of above-mentioned efficient alkyd resin corrosive enamel, including procedure below：
By the dryness long oil alkyd of 10~25 parts by weight, the dryness short oil-ity alcohol acid resin of 5~15 parts by weight and 15~
20-17 β of (s)-O- androstane-4- alkene-acyl group camptothecine of 40 parts by weight and the volume ratio of 50~80 parts by weight are 5:2 to diformazan
Benzene and butyl acetate admixture solvent are together added in retort and stirred, and are further continued for the talcum powder of 5~20 parts by weight, 5
The bentonite of~15 parts by weight, the dispersant polyethylene glycol 200 of 1~10 parts by weight, the levelling agent of 1~8 parts by weight are polyether-modified
Dimethicone Copolyol body, 1~6 parts by weight drier aphthenic acids manganese salt together put into retort high speed stirring 1
Hour produces；
Experiment find, with dryness long oil alkyd, dryness short oil-ity alcohol acid resin and the β of 20 (s)-O- androstane-4- alkene-17-
Acyl group camptothecine is film forming matter, using paraxylene and butyl acetate mixture as solvent, adds talcum powder, bentonite, divides
Prepared by the manganese salt of the polyether-modified Dimethicone Copolyol body of powder polyethylene glycol 200, levelling agent and drier aphthenic acids
Alkyd resin corrosive enamel, is sprayed in tinplate sheet, tests and is not risen when being soaked 100 hours in 3.5% sodium chloride solution
Steep, do not ftracture, do not fall off；Tested on electrochemical operation, bare area is 1 square centimeter, and AC impedance is more than 500 k Ω
.cm2, therefore, the alkyd resin corrosive enamel of preparation has higher Corrosion Protection, more than current alkyd 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 alkyd resin corrosive enamel in embodiment 1.
