Description
Technical field
The invention belongs to anti-corrosion material technical field more particularly to a kind of preparation methods of anticorrosive paint.
Background technique
Corrosion is that the objects such as metal, concrete, timber are damaged by chemical action or the electrochemical action of surrounding medium
Bad phenomenon.Corrosion is arch enemy of man, according to ASSOCIATE STATISTICS, the whole world every year because corrosion caused by economic loss be up to 1,000,000,000,000
Dollar, about the natural calamities such as earthquake, floods, typhoon cause 6 times of economic loss summation, account for various countries' gross national product
2%-4%.
Timber is a kind of natural organic-biological material, and main ingredient includes cellulose, hemicellulose and lignin etc.,
The essential element of composition is carbon, hydrogen, oxygen etc., and timber is widely used in Furniture manufacture and building industry.Timber-work in order to prevent
It degenerates, prolongs the service life, need to carry out necessary protection to it, conventional way is usually on the surface of timber at present
One layer of anticorrosive paint is coated, prevents extraneous water, worm, mould etc. from causing to corrode to timber.
The anticorrosive paint that conventional method is prepared requires wood surface humidity, finish higher, and wood surface is deposited
In impurity, surface is not smooth enough, the excessively high effect that can all seriously affect coating coating of timber water content, therefore constructs at the scene
It need to take considerable time and wood surface is handled, the finish and humidity of strict control wood surface avoid wood surface
Impurity is excessive, humidity is excessive, the large labor intensity of worker, integral construction low efficiency.And anticorrosive paint made from conventional method
Poor permeability, coating, which cannot well contain timber, to be sealed, and reduces anti-corrosion effect and corrosion protection service life.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of anticorrosive paint, to solve the painting that existing method is prepared
Expect poor permeability, to the demanding problem of substrate surface treatment.
In order to achieve the above object, base case of the invention are as follows: a kind of preparation method of anticorrosive paint, including following step
It is rapid:
(1) prepare the raw material of following mass fraction: 40-65 parts of the copolymer of ethylene, propylene and hexadiene, isopropyl isobutyrate
15-30 parts, 20-35 parts of solvent, 15-30 parts of pigment, 0.5-3.8 parts of auxiliary agent, 7-12 parts of filler, 8-12 parts of anticorrosive；
(2) isopropyl isobutyrate and ethylene, propylene are mixed with the copolymer of hexadiene, are then stirred, stir 10-45min,
Obtain the first mixture；
(3) the first mixture and anticorrosive are added in the first reaction kettle, temperature is controlled at 106-417 DEG C, reacts 60-
480min obtains spherical network macromolecule resin；
(4) solvent and auxiliary agent are mixed, pigment and filler is added after 5-10min, stirred 5-15min, then put into
In second reaction kettle, at 150-320 DEG C, the wire velocity control of stirring reacts 20-150min in 5-20m/s for temperature control；
(5) in material investment third reaction kettle step (3) and (4) being prepared, temperature is controlled at 25-36 DEG C, instead
10-75min between seasonable；
(6) material stirring that step (5) is prepared, the wire velocity control of stirring stir 5-65min in 8-22m/s,
Obtain anticorrosive paint.
The beneficial effect of this base case is:
1, isopropyl isobutyrate and ethylene, propylene are mixed with the copolymer of hexadiene, and it is high that specific spherical network is prepared
Resin component of the molecule resin as coating, spherical network macromolecule resin have excellent wellability and permeability, can replace
The moisture of wood surface forms successional coating, effectively completely cuts off infringement of the extraneous corrosive medium to timber.Since coating can
The moisture of wood surface is replaced, when coating coating, the ponding of wood surface need to be only cleared up, be not required to the humidity of strict control timber,
Drying steps before coating is omitted reduce labor intensity, improve processing efficiency.
2, the coating that this method is prepared needs corrosion-resistant working condition suitable for various, can be in different substrate materials (base
Material be timber using effect more preferably), different extent of corrosion, the coating in the case of different humidity, serious forgiveness is high.The coating can make existing
Field maintenance becomes simple possible, compared with prior art, can really solve the problems, such as band wet bands corruption coating, and make antiseptic property
Effectively promoted.
Further, the anticorrosive preparation the following steps are included:

DEG C, ball milling 0.6-1.5h obtains anticorrosive.
Step b pre-processes graphite powder, and the oxidation of the subsequent graphene being prepared can be improved after pretreatment
Degree, through applicants have found that, the degree of oxidation of anticorrosive is higher, and its corrosion-resistant performance is better.Metal is added in step c
Ceramic particle, ceramic particles had not only had the toughness of metal, good thermal stability, but also had the high temperature resistant of ceramics, corrosion resistant
Erosion and anti abrasive characteristic can obviously improve the comprehensive performance of the mechanical resistant impact and heat shock resistance of coating.In preprocessing process
Magnetization treatment is loaded, is conducive to the coordinated of graphene and ceramic particles, enhances etch-proof effect.Add anticorrosion
The specific antiseptic principle of agent are as follows: by processing preparation, contain a large amount of graphene oxide in anticorrosive, graphene oxide passes through
Be layering and it is effective it is evenly dispersed after, can form a three-dimensional three-dimensional structure (part metals in product surface
Ceramic particle is dispersed in three-dimensional structure, helps to strengthen the three-dimensional structure), it is flat that a filling can be obtained to product surface projection
Face plays the role of obstructing oxygen and water in environment, to reach anti-corrosion purpose.
Further, the filler includes following raw material: nano zine oxide and filler, nano zine oxide and filler quality
Portion rate is 1:0.5-2；The preparation of the filler infiltrates the following steps are included: montmorillonite is put into NaCL ethanol solution,
