Description
Technical field
The invention belongs to coating preparation fields, are related to a kind of outdoor salt spray resistance powdery paints.
Background technique
In coating spraying process organic solvent volatilization be always air pollution one of main source, especially at present I
The haze weather that state various regions frequently occur even more proposes a urgent demand to coating industry.Relative to liquid coating
Speech, powdery paints do not use solvent, solvent-free volatilization in application process, and high, the easy to operate, productivity with recovery utilization rate
It the advantages that height, coating fast drying, therefore, is widely adopted in fields such as automobile, household electrical appliance, machinery, building, ships, to replace
For liquid coating.
Currently, the coating that the powdery paints of common HAA powder coating formulation is formed, has many advantages, such as nontoxic, good weatherability,
But when use environment slightly becomes more harsh, for example, being exposed under corrosive environment for a long time than high temperature and humidity, such as acid
Rain, haze, coastal climate etc. can all be obviously shortened the useful life time of coating, accelerate coating corrosion failure, appearance and performance
It runs down, is generallyd use in existing dope preparing process and directly add polyphenyl amine hardener in epoxy resin, realize coating
Salt spray resistance, but the mobility of epoxy resin is smaller, be easy to cause dispersing polyaniline uneven in mixed process, and
And the coating thermal stability of preparation is lower, and pollution environment is easy when polyaniline additional amount is larger.
Summary of the invention
The purpose of the present invention is to provide a kind of outdoor salt spray resistance powdery paints, contain in the powder coating formulation a certain amount of
Polyaniline, in acid condition, occur anodic oxidation reactions, formed surface passivation layer, even if corrosive deposit immerse, passivation layer
It can be used as the second barrier, the generation of corrosion can be also hindered, ensure that the salt spray resistance of coating, while in dope preparing process
It using polyester resin as matrix resin, due to polyester resin wetability with higher, can sufficiently be mixed with polyaniline, so that poly-
Aniline is evenly dispersed in coating, and a small amount of polyaniline, which is added, can be realized coating salt spray resistance, and not pollute the environment.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of open air salt spray resistance powdery paints, is made of the component of following mass percent:
Preferably, the polyester resin acid value is 28-32mgKOH/g；
Preferably, the smooth degasifier is synthesis microwax；
Preferably, the levelling agent is acrylate copolymer；
Preferably, the polyaniline is conductive state, conductivity is greater than 2S/cm, and partial size is less than 30 μm.
Beneficial effects of the present invention:
Contain a certain amount of polyaniline in powder coating formulation of the present invention, in acid condition, anodic oxidation reactions occur,
Surface passivation layer is formed, even if corrosive deposit immerses, passivation layer can be used as the second barrier, can also hinder the generation of corrosion, guarantee
The salt spray resistance of coating, while using polyester resin as matrix resin in dope preparing process, since polyester resin has
Higher wetability can be mixed sufficiently with polyaniline, so that polyaniline is evenly dispersed in coating, a small amount of polyaniline is added
Coating salt spray resistance can be realized, and do not pollute the environment.
Powdery paints of the present invention using safety, low toxicity beta-hydroxy alkylamide as curing agent, therefore have it is safe,
The features such as environmentally friendly.
