Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of engineering machinery epoxy primer and its preparation side
Method.
Background technology
Suitable primer coating is the premise that finishing coat is durable, beautiful, and engineering machinery priming paint must possess following properties：
(1) barrier propterty, mainly corrosion protection performance, engineering machinery are substantially outdoor storage and open work, and some even exists
Operation under damp and hot, coastal environments, and working condition is severe, therefore the corrosion protection effect of coating is for extending engineering machinery
The service life appearance good with holding is most important；(2) mechanical performance, including hardness, impact property, pliability, adhesive force
Deng if paint film mechanical performance is bad, paint film is easily destroyed in the assembling, transport and the course of work of part or complete machine, loses
Go the effect of corrosion protection；(3) workability, the barrier propterty and mechanical performance of priming paint must construct to form paint film by priming paint
To realize, the construction of priming paint can also directly influence the coating quality of production cost, efficiency and finishing coat, the workability master of priming paint
Show drying time, levelability, flow and service life etc..Resin according to used in priming paint, can be by engineering machinery
Common priming paint is divided into alcohol acid primer, epoxy ester undercoat, acrylic primer and polyurethane primer etc.；, can according to the purposes of priming paint
The common priming paint of engineering machinery is divided into anti-corrosive primer, oil resistant primer, solderable priming paint and high temperature resistant primer etc., anti-corrosive primer is used
Lay the first stone in common parts corrosion protection and for topcoat, oil resistant primer is used for hydraulic components, it is desirable to which coating has good
Good oil resistivity, solderable priming paint are used for the pretreatment of the antirust and steel between master operation, and high temperature resistant primer is mainly used for starting
Machine component or annex are as exhaust pipe, muffler, paint film heat resisting temperature more than 600 DEG C.Whether can containing solvent according to coating
It is divided into solvent based coating, electrophoretic coating and powdery paints.Electrophoretic coating and application are in industries such as automobile, building materials, hardware, household electrical appliances
It is widely used, but the application in construction machinery industry is also fewer.Constructional Machinery is more and appearance and size
It is larger, all it is unsuitable for using electrophoresis from cost and technological angle.Powdery paints and its application for construction machinery industry still
One new process, powdery paints can be painted on metal surface, have the function of priming paint and finishing coat concurrently, can also be sprayed on bottom
On lacquer coat, play role in decoration, it is common to have epoxide powder coating, epoxy polyester powdery paints, polyester powder coating, propylene
Sour powdery paints etc..
It is using a variety of macromolecule resins as base-material as the water paint in solvent reducible coatings, water is decentralized medium, than passing
The solvent based coating of system has low VOC (VOC), is green, safety, Environmentally friendly coatings.Water paint
In contained water oxygen mixture when being contacted with metal surface, will instantaneously produce corrosion phenomena, and commonly referred to as " dodge erosion ", produced
Raw rusty scale will seriously affect the anti-corrosion effect and service life of coating, restrict the popularization and application of waterborne metal anti-corrosive paint,
So it is also one of main problem that waterborne metal anti-corrosive paint exploitation must solve to improve anti-corrosion of dodging.
Chinese invention patent CN105199559A discloses a kind of salt spray resistance waterborne polyester priming paint and preparation method thereof, the bottom
Paint is made of aqueous polyester resin, curing agent, defoamer part, levelling agent, filler and water, and the priming paint which provides has environmental protection
The performances such as performance, anti-corrosion function and raising adhesive ability, available for the appearance application of the vehicles such as automobile, agricultural locomotive, but
The execution conditions and complexity of the priming paint are unknown.Chinese invention patent CN102382540A discloses a kind of high glaze engineering machine
Tool chassis water-based anticorrosive paint, raw material include water-base resin, drier, neutralizer, dispersant, color stuffing, anti-settling agent, wetting
Agent, levelling agent, thixotropic thickening agent, defoamer, anti-flash corrosion inhibitor, cosolvent and deionized water, the water-based anticorrosive paint tool of the invention
There is excellent antiseptic property, there is the excellent corrosion resistance of anti-corrosive primer, current solvent-borne type chassis paint, coating can be substituted completely
Possess good physicochemical property and corrosion resistance, but the execution conditions of the priming paint and complexity are equally unknown.Middle promulgated by the State Council
Bright patent document CN105949958A discloses a kind of waterborne epoxy modified polyamine curing agent and water-base epoxy anti-corrosion primer, the hair
Bright curing agent can direct emulsion epoxy resin, bin stability and good mechanical stability, water-base epoxy anti-corrosion primer is by group
Part A and component B compositions, component A include domestic E51 epoxy resin, and B component raw material has waterborne epoxy modified polyamine curing agent, goes
Ionized water, dispersant, defoamer, titanium dioxide, iron oxide black, blanc fixe, aluminium triphosphate, water-based bentonite, anti-flash rusting
Auxiliary agent, base material wetting, defoamer and thickener, the priming paint which provides avoid aqueous epoxy emulsion bin stability difference or
The shortcomings that mechanical stability is poor, and since epoxy resin ingredient is not required to carry out hydrophilic modifying, it is ensured that the chemically-resistant of film
Medicine is functional, but the curing agent preparation process used in the invention is complex.
In conclusion existing water-base epoxy priming paint has dry slow, hardly possible construction, easily produced under super-humid conditions and dodge erosion
Problem.
The content of the invention
Existing in the prior art to solve the problems, such as, an object of the present invention is by specific curing agent and epoxy emulsion
It is combined, the auxiliary agent of appropriate mix, obtains under quick-drying, easily construction and super-humid conditions without the high-performance engineering machinery water for dodging erosion
