Abstract
The invention discloses a kind of aqueous bottom surface unification band rust coating anticorrosive paint and preparation method thereof, joined the polyenoid acid ester monomer in addition to acrylic acid in acrylic emulsion, and with carboxylic acid reaction and can participate in stage by stage reaction functional group monomer.The coating has fabulous adhesive force on rust iron surface, can apply with rust, also the characteristic with bottom surface unification；More importantly the coating gloss of coating preparation provided by the present invention, storage stability are good, corrosion resisting property is good.
Description
Technical field
The present invention relates to Metal surface anti-corrosion application techniques fields, concretely relate to a kind of aqueous bottom surface unification band rust
Coat anticorrosive paint and preparation method thereof.
Background technique
With the fast development of economic construction of China and national economy, various steel constructions, concrete structure, plastic-aluminum structure etc.
It is more and more applied in the industry such as bridge, building, harbour, traffic and civil engineering, but it easily corrodes (corrosion)
Feature brings huge economic losses to equipment manufacture, and damages natural resources and enviroment protection.In various anticorrosion techniques
In, coating plays a very good protection to various engineering products and facility.A series of anticorrosion erosion is developed in succession both at home and abroad to apply
Material, including on rust paint, but most of is solvent type.Solvent based coating VOC content is high, causes to pollute environment, aggravates haze
It is formed.Therefore, the environment-friendly aqueous coating for developing low VOC content is necessary.
Many big machinery equipments are in maintenance process, the existing certain thickness corrosion layer of part of the surface, in order to obtain
Good corrosion resistance is obtained, the iron rust on steel must be thoroughly removed before coating, coating is made directly to be in contact with steel surface,
Otherwise it will affect anti-corrosion effect.It is derusted using craft or electric tool, it is large labor intensity, costly, and it is difficult to ensure derusting
Quality.It is therefore necessary to develop a kind of new coating capable of coating with rust.
The shortcomings that anticorrosive coating promoted at present is the coating system frequently with 2 layers or more, and epoxy primer cooperates propylene
Acid or polyurethane finish etc., belong to the product of multilayer system, are easy to lead to the problem of because interlayer matching is bad, and construction period is normal,
It lacks competitiveness in the environment of labour's growing tension.Current more successful water-based anticorrosive paint is all that bottom surface paint is separately brushed
It applies, construction trouble, and is also contemplated that the matching problem of bottom surface paint.If can letter province using primer-topcoat integrated anticorrosive coating
Process is conducive to construction.
