Description
Technical field
The present invention relates to a kind of protective system, be specifically related to a kind of to there is cloudy guarantor and antistatic property
Compound waterborne inorganic anti-corrosion paint and preparation method.
Technical background
Zinc-rich paint is a kind of protective system with galvanic protection effect; in zinc-rich paint, the content of zinc powder is very high; can up to 90% (weight ratio); like this in its dry film between zinc particle; contact with each other between zinc powder and steel substrate; under this kind of state; when moisture invades in paint film; namely microbattery is formed between zinc powder and steel substrate; because zinc is the metal (current potential is low) sprinkled than ironwork in electrochemistry; so just flow through anticorrosive current from zinc powder to iron and steel, thus cathode protection effect is played to iron and steel.
Also there is a lot of problem in current zinc-rich paint, the general weathering resistance of organic coating, thermotolerance are not fine, and physical strength is not high, and easily aging, electric conductivity is low, is unfavorable for galvanic protection; Solvent based coating VOC content is high, during dried coating film, volatilizes organic gas inflammable, explosive, poisonous in a large number, and large to human injury, potential safety hazard is high, and environmental pollution is large; Water-borne coatings is the direction of future development on the whole, but in actual applications, still there is a lot of problem, as the time of doing solid work is longer, to envrionment temperature and humidity requirement high, bad to iron and steel sticking power, easily cause ablation etc.; The current Problems existing of inorganic zinc coating mainly concentrates in the research to its auxiliary aid, particularly high-module silicate zinc-rich paint has very outstanding antiseptic property, the occasion of multiple circumstance complication can be applied to, but deposit free settling, the large easily gel of viscosity, these are all problem demanding prompt solutions.
Theoretically, zinc content is higher, and galvanic protection effect is better; But; difference due to corrosive environment in Practical Project often falls flat; as; in the place that water-wet is serious; in film, the stripping of zinc powder is more severe, and what at this moment zinc content was large easily causes paint blister, and therefore during application, zinc content can not be too high; general not higher than 70%, this just have impact on galvanic protection effect greatly.
For solving the problem, product of the present invention adopts graphene oxide and the composite making protective system of zinc powder, namely ensure that anticathode protects the contact of the most basic condition-metal/metal, has again good mechanical property and antiseptic property.
