The solid content of the chlorosulfonated polyethylene emulsion is 30-60%；The concentration of salpeter solution is 0.5-2mol/L；Ammonium hydrogen carbonate The concentration of solution is 1-5mol/L.
Described a kind of heat-staple rare earth modified hydrophilic chlorosulfonated polyethylene anticorrosive paint and preparation method thereof, its feature It is to be made up of following steps：
A. chlorosulfonated polyethylene emulsion, algae clay, organo montmorillonite, deionized water, dodecyl sodium sulfonate are put into emulsifier Sodium, is prepared into primary emulsion, then the removed under reduced pressure organic solvent in evaporating kettle, obtains chlorosulfonated polyethylene latex；
B. add salpeter solution to be dissolved into transparence liquid lanthana, add talcum powder and ammonium bicarbonate soln, lanthanum ion and carbon Sour hydrogen ammonium acts on forming precipitation, attaches on talcum powder, synthesizing rare-earth carbonate precursor, and Jing is filtered, washed, being dried, calcination Afterwards, rare-earth additive is obtained；
C. by step b gained rare-earth additive and titanium dioxide, nanometer zirconium sesquioxide, electrically conductive graphite, deionized water mixing, add Aqueous epoxy resins, polyacrylic acid, then grind on grinder, granularity is obtained<30 μm of mill base；
D. step c gained mill base is mixed with step a gained chlorosulfonated polyethylene latex, adds silane coupler KH560, adopted Magnetic stirrer 6-10h is used, makes coating be uniformly dispersed as far as possible, obtain final product the modified hydrophilic chlorosulfonated polyethylene of rare-earth additive Anticorrosive paint.
Described a kind of heat-staple rare earth modified hydrophilic chlorosulfonated polyethylene anticorrosive paint and preparation method thereof, its feature It is that emulsification times are 10-30min in step a.
The invention has the beneficial effects as follows：Rare-earth complex has stronger ligand complex function, big with chlorosulfonated polyethylene Chlorosulfonyl group reaction on strand generates cross-bond, increases the degree of cross linking of molecular structure；Numerous unoccupied orbitals of rare earth ion Unstable free radical can be caught, causes it to lose activity, be conducive to stabilization, improve corrosion resistance and resistance to ag(e)ing；This Outward, promote free radical to produce by the variation of valence of contained rare earth ion, accelerate coating oxidation polymerization to be dried；By talcum powder with it is dilute Earth compounds are combined, and improve wearability, the glossiness of coating；Add static conductive graphite in coating, there is coating excellent Static conductive, anti-electromagnetic interference performance, the coating for obtaining be applied to various equipment protective coating；Cooperation with the addition of organic illiteracy and take off Soil etc., enhances the heat endurance of coating.
