Abstract
The invention discloses a method for preparing connection paint from rosin-modified acrylate. The method comprises putting 10-15 parts by weight of rosin-modified acrylate resin, 6-10 parts by weight of chlorinated rubber, 14-24 parts by weight of xylene and 4-8.7 parts by weight of n-butanol into a high-speed dispersion machine together, carrying out stirring to obtain a uniform mixture, putting 0.8-1.2 parts by weight of organobentonite into the high-speed dispersion machine, carrying out high-speed dispersion for 15-20min, putting 20-30 parts by weight of iron-titanium compound powder, 20-25 parts by weight of mica powder and 3-8 parts by weight of titanium dioxide into the high-speed dispersion machine, and carrying out high-speed dispersion for 30min to obtain the connection paint. A test proves that the connection paint has fineness controlled below 100 microns. The connection paint has good film-forming property, high connectivity to anti-fouling paint and anti-rust paint, prevents time interval of the connection paint coating and anti-fouling paint coating and has good connection strength.
Description
Technical field
The invention belongs to technical field of coatings, the specifically present invention are a kind of preparations by Abietyl modified acrylate connect
The method of coating.
Connect coating using one-component prepared by Abietyl modified acrylate and be applied to ship outer casing underwater position, be
A kind of coating of transition between antirusting paint and antifouling paint.
Background technology
In order to ensure that ship outer casing underwater position, from seawater corrosion and sea organism attachment, is needed in the position application
Antirusting paint and antifouling paint, but antirusting paint and antifouling paint exist different due to its property, using function etc., cause antirust
Coating is different with the curing mechanism of antifouling paint.Antirusting paint mostly is epoxy double-component thermohardening lacquer, surface ratio after its solidification
More smooth densification, lacks anchor point；And antifouling paint mostly is one-component thermoplastic coating, which has resin corrosion and release antifouling
The characteristic of agent, therefore the intensity of antifouling paint is not typically high and has certain water imbibition.If directly coated on antirusting paint
Antifouling paint, antifouling paint easily come off under seawater eroding, lose antifouling property.
The attachment issue of antifouling paint is solved, the best approach is to introduce transition zone between antirusting paint and antifouling paint,
Sealing paint in the middle of connecting coating or being referred to as, connection coating must play double faced adhesive tape effect.
Chinese patent CN102964516A disclose a kind of single-component epoxy base it is acrylic resin modified and its application, this
Bright mentioning uses epoxy-modified acrylic resin, and although prepared connection paint is effectively improved to antirust paint adhesive strength and antifouling
Paint bonding strength, but painting interlayer failure mechanics still have 10% connection paint and priming paint interlaminar failure, 10% anti-fouling paint and connection
Paint interlaminar failure, and anti-fouling paint be connected the overlay painting interval needs 7 days that paint.
In addition existing one-component connection coating also has chlorinated rubber type, and which has one to antirusting paint and antifouling paint
Fixed attachment and switching performance, but it is not high to the adhesive strength of antirusting paint, and its intensity is not higher than 2.0MPa.And chlorinated rubber
Differ greatly with epoxy molecule structure and polar functional group, chlorinated rubber is coated in the fine and close epoxy primer of completion of cure
On adhesion property it is poor, actual application requires which to antirust paint overlay painting interval within 24h, it is seen that its intensity and application
Interval still suffers from defect.
Relevant report yet there are no by the Abietyl modified method for preparing one-component connection coating into acrylic resin.
The content of the invention
For solving the above problems, the invention provides a kind of method that connection coating is prepared by Abietyl modified acrylate,
The connection coating that the method is prepared is respectively provided with high-adhesion to antirusting paint and antifouling paint, most long 8 days to antirusting paint
Hardening time and do not limit overlay painting interval to antifouling paint, preferably resolve connection coating adhesive strength and application between
Every preparation method is simple, easy construction.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of method for preparing connection coating by Abietyl modified acrylate, the method use Abietyl modified acrylate
Resin, chlorinated rubber, thixotropic agent, color stuffing and solvent, Abietyl modified acrylic resin are methyl methacrylate, metering system
The copolymer of acid butyl ester and rosin and Chemical market is on sale, the feature of the present invention are as follows：
It is required that the molecular weight Mw of Abietyl modified acrylate is controlled 50000～100000, thixotropic agent is organic bentonite
Profit soil；Color stuffing is ferrotitanium powder, mica powder and titanium dioxide；Solvent is dimethylbenzene and n-butanol；
By the Abietyl modified acrylate of 10～15 weight portions, the chlorinated rubber of 6～10 weight portions, 14～24 weight
The n-butanol of the dimethylbenzene and 4～8.7 weight portions of part stirs in together putting high speed dispersor into, afterwards by 0.8～1.2 weight
The organobentonite of amount part is put high speed dispersor high speed into and disperses 15～20min, followed by by the ferrotitanium of 20～30 weight portions
The titanium dioxide of powder, the mica powder of 20～25 weight portions and 3～8 weight portions together puts high speed dispersor high speed dispersion 30min into
Connection coating can be prepared, require that the fineness of connection coating is controlled below 100 μm after testing.
As using techniques described above scheme, the present invention produces following good effect：
1st, its good film-forming property of connection coating of the invention is high to the switching performance of antirusting paint and antifouling paint.
2nd, connection coating and antifouling paint of the invention can also keep good connection intensity without overlay painting interval time restriction.
Specific embodiment
The present invention is a kind of method for preparing connection coating by Abietyl modified acrylate, present invention mainly solves connection
Coating can not be provided simultaneously with the shortcoming of high intensity connection and long overlay painting interval.
The present invention with molecular weight Mw be 50000～100000 Abietyl modified acrylic resin based on base-material, with chlorination rubber
Glue is auxiliary base-material, is equipped with dimethylbenzene, n-butanol, organobentonite, ferrotitanium powder, mica powder and titanium dioxide and prepares connection painting
Material, the Abietyl modified acrylate for using, chlorinated rubber, dimethylbenzene, n-butanol, organobentonite, ferrotitanium powder, mica
Powder, titanium dioxide are industrial raw material and Chemical market is on sale, and wherein organobentonite belongs to thixotropic agent, ferrotitanium powder, mica powder
