Description
Technical field
The invention belongs to special coating technical fields, and in particular to a kind of polytetrafluoroethylmodified modified chemical-resistant reagent special type is anti-
The preparation method of rotten coating.
Technical background
The development of chemical industry has become an important indicator for influencing national economy, especially with electric power, petroleum, chemical industry
Etc. industries, each enterprise be owned by a considerable amount of chemical reagent, especially acid, the storage tank of alkali equal solvent, storage tank and transport set
Standby, enterprise requires to put into a large amount of human and material resources, financial resources every year as equipment progress care and maintenance.
Special anticorrosive coating due to it is at low cost, easy for construction, have good decorative effect, by more and more
The favor of enterprise, a large amount of chemically-resistant solvent sapecial coating in the market, mainly using epoxy resin or modified epoxy as at
Film object, the infiltration that can withstand most of chemical solvents cause to corrode to equipment, and have good adhesive force and application property
Can, have become the first choice of most of chemically-resistant coatings volatile organic compounds, but due to epoxy resin or modified epoxy weatherability compared with
Difference generally cannot function as outdoor equipment finishing coat, and service life is shorter in oxidisability chemical solvent, so, exploitation is new
The special anticorrosive coating of type can just better meet the demand in market.
Polytetrafluoroethylene (PTFE) (PTFE) is high-molecular compound made of tetrafluoroethene is aggregated, has the title of King, has
The characteristics such as excellent chemical stability, corrosion resistance, high lubrication and non-stickiness.
The invention patent is drawn on fluororesin main chain in the method for tetrafluoroethylene monomer and functional form monomer copolymerization
The monomer for entering part functional group reduces the crystalline modified polytetrafluoroethylresin resin of original fluororesin as main film forming matter
Matter adds the bi-component air-curing coatings of the compositions such as wear-resistant acid and alkali-resistance filler, polytetrafluoroethylene powder (PTFE), nanoparticle.
Due to addition PTFE powder, more F-C keys are introduced, since F-C key is a kind of chemical bond of high energy, it is excellent to assign coating
The excellent performances such as different guarantor light colour retention, weatherability, heat-resisting, corrosion-resistant, chemicals-resistant, stain resistant.The addition of nanoparticle,
It reduces corrosive media diffusion rate in the coating and reduces the rate of corrosion process, coating impedance is larger in addition, resists
Cathodic disbonding ability is strong, thus plays to corrosion and effectively prevent.
Summary of the invention
For most of chemically-resistant solvent sapecial coatings currently on the market there are the drawbacks of, this patent discloses one kind poly- four
The preparation method of fluoride modified chemical-resistant reagent special anticorrosive coating.With tetrafluoroethylene monomer and functional form monomer copolymerization
Method introducing portion functional group on fluororesin main chain monomer, reduce the crystalline modified polytetrafluoroethyl-ne of original fluororesin
Olefine resin adds the compositions such as wear-resistant acid and alkali-resistance filler, polytetrafluoroethylene powder (PTFE), nanoparticle as main film forming substance
Bi-component air-curing coatings.Since PTFE powder is added, more F-C keys are introduced, since F-C key is a kind of chemistry of high energy
Therefore key assigns the excellent guarantor's light colour retention of coating, weatherability, heat-resisting, corrosion-resistant, chemicals-resistant, stain resistant, resistance to oxidation etc.
