Description
Technical field
The invention belongs to paint field, and in particular to a kind of environmental friendly, anti-corrosive erosion building coating and preparation method thereof.
Background technology
The chemical products that coating is a kind of easy construction, cheap, effect is obvious, value-added rates is high.It can not only
The surfaces such as decorative architecture, ship, machinery, and with preventing its surface corrosion, the function of increasing the service life, also decorative environment
The enjoyment and the function of eye-catching mark of U.S. are given, with continuing to develop for science and technology, coating progressively turns into that a kind of specificity is strong, work(
Can the strong fine chemistry product of property.
Anticorrosive paint, is generally divided into conventional anticorrosive paint and anticorrosive paint, is essential one kind in paint
Coating.Conventional anticorrosive paint is under general condition, etch-proof effect, the longevity that protection non-ferrous metal is used to be played to metal etc.
Life；For anticorrosive paint refers to relatively conventional anticorrosive paint, can be applied in relatively harsh corrosive environment, and with can reach
The one class anticorrosive paint of protection period longer than conventional anticorrosive paint.Anticorrosive paint is generally used for emerging ocean engineering such as sea and sets
Apply, the field, Modern Traffic transport such as freeway guardrail, bridge field, large size industrial enterprise such as seashore and bay structure
Such as food chemistry equipment, canister inside and outside wall, chemical industry, steel field.Anticorrosive paint is main with conventional anticorrosive paint
Difference is that its technology content is higher, and technical difficulty is larger, is related to perhaps many technological progresses and product development, and it is no longer
It is undue to rely on the knowledge and experience of coating, but know depending on electronics, physics, ecology, machinery, instrument and management etc. are multi-disciplinary
Know and cross, the synthesis of corrosion-resistant resin high, the application of dispersant with high efficiency and auxiliary rheological agents, the impervious pigment of new type corrosion resistant and filler
Exploitation, the application of advanced construction tool, construction maintenance technology, onthe technology of site test etc., are required for integrated application to be applied to heavy antisepsis
Among material and application.So, the development level of anticorrosive paint is how, and performance is how, as mark one national science technology
The mark of level, as the mark for weighing anticorrosive paint advanced technology.CN 1013146958 discloses a kind of for steel construction guarantor
The environment-friendly epoxy glass squama antiseptic paint of shield, its formula is：Epoxy resin 22.85%-24.65%, amine additives curing agent
26.27%-28.35%, modifying agent 1.36%-1.85%, glass flake 6.20%-8.20%, rust resisting pigment 8.82%-10.80 %, face
Filler 15.89%-16.33%, auxiliary agent and mixed solvent.Its preparation method is：First component is prepared, by epoxy resin and auxiliary agent, is changed
Property agent, mixed solvent be uniformly dispersed, add color stuffing and glass flake, it is qualified to be dispersed to fineness through high speed, and mixes colours;Prepare
Component B, prepares amine additives, and adds anti-settling agent and color stuffing, is uniformly dispersed through high speed.First will paint and solidification during construction
Agent stirs respectively, then by volume 1:1 allotment is uniform, and is adjusted to working viscosity with diluent, application of then constructing.So
And, the film forming thickness of existing anticorrosive paint, workability, environmental-protecting performance and weather-proof, adhesion property all also not exclusively meet
The requirement of various environment, develops the emphasis that the anticorrosive coating city of excellent combination property will research and develop from now on.
The good stain resistance of coating is always the main selling point of coating, there are a large amount of various dirts in the modern life
Stain, there is aqueous, oil-dirt, and liquid, solid spot, most spots are all difficult to be wiped out, and paint film quilt generally occurs
Wipe light not only that shedding or paint film wiped but also bright, and there is very big difference on gloss in surrounding face.This is primarily due to
Common product hardness of paint film is not high, product
Product formula PVC (pigment volume concentration (PVC)) are too high and paint film requires matte effect, and paint film is not fine and close enough, paint film is easily received spot
Pollution is penetrated into and is difficult cleaning and wipes.Coating of the exploitation with good stain resistance is also the important directions of coating research from now on.
The content of the invention
It is an object of the invention to provide the comprehensive environmental protection coating material that a kind of Corrosion Protection and stain resistance are very excellent
And the preparation method of the coating.
To solve the above problems, the technical solution adopted by the present invention is：
