Description
Technical field
The present invention relates to a kind of paint fields, in particular for the fluorocarbon coating of paralic environment antiseptic concrete erosion.
Background technique
Concrete structure is used for a variety of occasions at this stage, however, being in paralic environment due to the corrosive environment of ocean harshness
Concrete by sunlight exposure, humid air, acid-alkali salt etc. corrode.It was verified that concrete surface protective coating is wherein
Most simple and effective measure.The coating of antiseptic concrete erosion at present mainly has epoxy coating, acrylate paint, organic siliconresin to apply
Material etc..Although these coating have excellent antiseptic property, also have the shortcomings that respective.Epoxy coating is due to epoxy molecule
In contain ehter bond, molecular resin degradable chain rupture under ultraviolet light irradiation, so the outdoor weathe resistance of film is poor, easy loss of gloss and powder
Change;And big to the dependence of temperature and humidity when epoxy resin cure, internal stress is big after solidification, and heat resistance is undesirable.Propylene
Acid esters water-resistant coating is poor, low temperature easily becomes fragile, high temperature becomes glutinous and loses by force, so as to cause the coating easily glutinous dirt, low contamination resistance.It is organic
Silicon resin coating has volatility, does not meet environment protection requirement.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, a kind of water-based fluorocarbon for antiseptic concrete erosion is provided
Coating carries out long-effective protection to concrete using the weatherability of fluorine-containing lotion, heat resistance, corrosion resistance and durability,
Using water as decentralized medium, organic solvent is free of, environment protection requirement is met.
The present invention to achieve the above object, using following technical scheme: it is a kind of for antiseptic concrete erosion water-based fluorocarbon
