Description
Technical field
The present invention relates to technical field of aqueous paint, more particularly to a kind of excellent watersoluble plumbago alkene metal of resistant storage properties is prevented
Rust priming paint and preparation method thereof.
Background technology
As coatings industry and application develop to low stainization, water paint increasingly rises.Caused by metal erosion
Loss is extremely serious, and the anticorrosive coating of metal material causes concern both at home and abroad.Solvent-borne type antirusting paint, exist atmosphere pollution,
Several aspect problems such as toxicity and fire hazard.Therefore develop water-thinned antirust primer to be taken seriously.Aqueous antirust paint is done with water
For decentralized medium, using the multiple rust-proof mechanism such as physics, chemistry, according to chemical conversion, the principles of chemistry such as network and reaction prepare and
Into being the optimal regeneration product of traditional anti-corrosive primer.Be widely used in various automobiles, ship, rack, machine-building, container,
The anti-corrosion protections such as railway, bridge, boiler, steel construction, petrochemical equipment, are that solvent-based paints are incomparable.
Acrylic acid ester emulsion protects color, protects light, and with good resistance to water, weatherability, resistance to acids and bases and corrosion resistance, therefore
And it is often used as the film forming objects system of traditional water-thinned antirust primer.There is easily migration when it is used as film forming matter, make
The impaired performances such as hardness, chemical-resistant, resistance to alcohol alkali resistance, the resistance to chalking of film, it is necessary to which acrylic acid ester emulsion is carried out
It is modified, while flash rusting can be caused after the moisture in traditional water-thinned antirust primer is contacted with steel surface, antiseptic property drastically under
Drop, is unfavorable for the antiseptic and rustproof protection of metal surface.
《The development of watersoluble plumbago alkene anti-corrosive primer》One text is created using Styrene-acrylic Emulsion as film forming matter
Addition Graphene of property etc. have developed a kind of environment-friendly aqueous Graphene anti-corrosive primer.The water developed by series of experiments
Property Graphene anti-corrosive primer property indices are fully achieved the technical indicator of even more than common anticorrosive paint, while meeting ring
Guaranteed request, and production and construction techniques are simple, easy to use, cost performance is high, with wide market application foreground.But in text
The water-thinned antirust primer of preparation has that adhesive force is not good, wearability is low, function is more single and excessive use styrene not energy-conservation
The defects such as environmental protection, need to be modified existing process and formula.
The chemical property of polystyrene foam plastics is more stable, with heat-insulated, sound insulation, shockproof, waterproof, acid and alkali-resistance, anti-
The characteristic such as burn into is ageing-resistant, have concurrently light weight it is attractive in appearance the advantages of, be one of most widely used plastics in the world, and mostly one
Secondary property is used, and waste product is become after use, non-aging in nature to rot, it is difficult to natural degradation and to be degraded by microorganisms, no
It is affine for natural environment, and waste polystyrene foam plastic is per se with various toxic chemical substances, it is necessary to changed
Property after substitute after styrene is modified to acrylic acid ester emulsion and be added in raw material, then other effective auxiliary agents of compatibility are so as to preparing
Go out to meet the new waterborne anti-corrosive primer of environmental requirement.
