Description
Technical field
The invention belongs to epoxy coating fields, and in particular to a kind of epoxy coating and preparation method thereof, coating process.
Background technique
After power transmission and transforming equipment puts into effect, since Service Environment is more severe, the paint film damage of matrix surface is very fast, generally
Maintenance need to be brushed again through 2~3 years；And need the equipment safeguarded often more dispersed, for being located in setting on field or mountain
It is standby, when maintenance is repaired, it tends to be difficult to reach the pre-treatment requirement of general aseptic base coat.GB/T 8923-2011 is " before coating coating
Steel surface processing " define the derusting grade before steel coating, it is however generally that, using injection or centrifugal blast cleaning (Sa) or power
Toolrust-removal (St) has good derusting effect, is easily guaranteed that the protection effect of coating；And power transmission and transforming equipment carries out old coating
When reparation, the method for not often being available electric grinding is surface-treated, and simple hand cleaning can only be carried out, to influence
The protection effect of conventional anticorrosive paint.
Meanwhile the concrete condition to maintain equipment is widely different, substrate types may be hot galvanizing, steel or aluminium alloy,
Matrix surface is also tended to containing old coatings such as acroleic acid polyurethane, epoxy, fluorine carbon；And existing anticorrosive paint, different matrix are suitable
Anticorrosive paint type is different, and after being directly coated on old coating, binding force and protective are also difficult to be guaranteed, this is resulted in
It when plant maintenance, can not be handled using unified processing method, on-site maintenance intricate operation, construction efficiency is low；For not
When carrying out maintenance construction with matrix situation, generally require to carry a variety of anticorrosive paints, bad adaptability simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of epoxy coatings, to solve in the prior art, the paint film of power transmission and transforming equipment is tieed up
The problem of protecting cumbersome working procedure, bad adaptability.
A second object of the present invention is to provide the preparation methods of above-mentioned epoxy coating.
Third object of the present invention is to provide the coating process for using above-mentioned epoxy coating.
In order to achieve the goal above, the technical scheme adopted by the invention is that:
A kind of epoxy coating, by iron red epoxy ester primer and Y2O3Composition, Y2O3Quality be iron red epoxy ester primer quality
0.05~0.25%.
Commercially available conventional variety can be used in iron red epoxy ester primer.Preferably, iron red epoxy ester primer is by following quality percentage
The group of ratio is grouped as: iron oxide red 21.00%~23.85%, zinc yellow 10.52%~12.52%, talcum powder 8.00%~9.00%,
ZnO6.00%~7.00%, lead naphthenate 0.06%~0.07%, cobalt naphthenate 0.018%~0.021%, manganese naphthenate
0.024%~0.027%, mixed solvent 4.8%~5.1%, surplus is epoxy ester resin；Mixed solvent is dimethylbenzene, butanol
By the mixture that the mass ratio of 7:3 forms, the solid of epoxy ester resin is divided into 50%.
Epoxy coating provided by the invention, iron red epoxy ester primer has good anti-corrosion ability, and has good
Water-fast, chemical resistance and thermal stability, film tough and hard wear resistant, but its appearance is poor with weatherability, is widely used in protective primer；Y2O3
The reactivity of epoxy coating can be increased, itself can also play the role of catalyst；It is added into iron red epoxy ester primer
Y2O3Afterwards, Y2O3Volatile de-electromation, be in positive oxidation state, reactivity is high, be participate in reaction high reactivity reagent and itself
Catalyst, and, iron red epoxy ester primer and Y extremely strong with gained compound bond energy after resin reaction2O3The result of synergistic effect makes this
The performances such as heat-resisting, wear-resisting, corrosion-resistant of invention gained epoxy coating are further enhanced.
The preparation method of above-mentioned epoxy coating, comprising: by Y2O3Partial size is ground to no more than 15 μm, then with iron oxide red epoxy ester
Priming paint be uniformly mixed to get.
The preparation method of epoxy coating provided by the invention, simple process, it can be achieved that directly deploy at the construction field (site)；Epoxy
Coating is one-component coating, and work progress is simple, and construction efficiency is high.
A kind of coating process using above-mentioned epoxy coating, comprising: pre-treatment is carried out to matrix to be processed, epoxy is applied and applies
Material makes 35~55 μm of thickness of dry film, and drying is to get primer coating.
For different matrixes to be processed, following manner can be used and carry out pre-treatment, then with the side of brushing, roller coating or spraying
Formula is constructed.
Matrix to be processed be hot dip Zinc Matrix when, the pre-treatment be polished using sand paper, after carried out clearly with acetone solvent
It washes.
When matrix to be processed is band rust hot dip Zinc Matrix, the pre-treatment is to be handled using steel brush to St3 grades.
When matrix to be processed is steel, the pre-treatment is to be handled using power tool to St2 grades, and roughness is greater than 50 μ
M, the oxide skin of surface non-loosening and obvious corrosion layer.
When matrix to be processed is band rust steel, the pre-treatment is to remove floating rust using sand paper polishing.
When matrix to be processed is alloy matrix aluminum, the pre-treatment is chemical conversion treatment, controls roughness >=3.2 μm.Chemical conversion
Market conventional aluminum alloys forming liquid can be used with forming liquid in processing.
When matrix to be processed is steel material, can be used blasting treatment or phosphorating treatment, blasting treatment control roughness >=
50 μm, phosphorating treatment controls roughness >=5 μm.
When matrix surface to be processed has acroleic acid polyurethane, epoxy or fluorine carbon old coating, the pre-treatment is using hand
Work or power tool are polished, and the old coating of damage or attachment loosely is removed.
When being constructed using aerial spraying, it is preferred that injection diameter is 2~3mm, and ejection pressure is 0.3~0.4MPa；Spraying
Twice, control thickness of dry film is 35~55 μm.After basecoat paint, can further spray paint, control finishing coat thickness of dry film
It is 35~55 μm.The spraying application parameter of finishing coat is identical as priming paint.
Coating process using above-mentioned epoxy coating of the invention is, it can be achieved that in hot galvanizing, band rust hot galvanizing, steel, band
The matrix surfaces such as rust steel, aluminium alloy are applied, and adaptability is good；Acroleic acid polyurethane, epoxy, fluorine carbon directly can also contained
Etc. carrying out reparation construction on old coating, the coating tensile strength after repairing is high, meets requirement.
Using coating process of the invention in the outdoor coatings reparation construction for carrying out power transmission and transforming equipment, it need only carry simple
Hand sand tool and epoxy coating of the invention, that is, be suitable for different matrix, on matrix different old coatings reparation construction,
Construction efficiency greatly promotes, and the coating binding force after reparation construction is good, and Corrosion Protection is good, extends the anti-corrosion of power transmission and transforming equipment
The time limit.
