Description

The rare earth modified hydrophilic chlorosulfonated polyethylene anticorrosive paint and its system of a kind of low-shrinkage Preparation Method
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of rare earth modified hydrophilic chlorosulfonated polyethylene of low-shrinkage Anticorrosive paint and preparation method thereof.
Background technology
Chloro-sulfonated polyethylene anti-corrosive coating is in the popularization and application eighties of 20th century.With the hair at full speed of modern industry level Exhibition, higher, the tightened up ability for bearing environmental corrosion is proposed to anticorrosive paint.The anti-corrosive properties of the coating of conventional formulation production Can typically be extremely difficult to require.Conventional chloro-sulfonated polyethylene anti-corrosive coating is mostly solvent type, not only causes a large amount of solvents Waste, and solvent for use is poisonous, volatile, and environment is polluted, and does not meet environmental requirement, and water paint has work Skill cleaning, advanced technology, low emission, low energy consumption, safe and harmless advantage, therefore, research hydrophilic chlorosulfonated polyethylene anti-corrosion is applied Material has great Social benefit and economic benefit.
Cao Hongzhang exists《Rare-earth additive modified water-soluble chloro-sulfonated polyethylene anti-corrosive coating performance study》In, using rare-earth additive Be obtained a kind of anticorrosive paint with chlorosulfonated polyethylene, but for anticorrosive paint as various equipment, also exist lead it is quiet Not excellent enough the shortcoming of Electricity Functional shortcoming, antiseptic property.
The content of the invention
Thinking based on more than, the present invention is intended to provide a kind of can be excellent with the antiseptic property of static conductive, anti-electromagnetic interference Hydrophilic chlorosulfonated polyethylene coating.
The technical problems to be solved by the invention are realized using following technical scheme：
The rare earth modified hydrophilic chlorosulfonated polyethylene anticorrosive paint of a kind of low-shrinkage, it is characterised in that be by following weight portion Raw material be made：

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.
Rare earth modified hydrophilic chlorosulfonated polyethylene anticorrosive paint of described a kind of low-shrinkage and preparation method thereof, it is special Levy and be, be made up of following steps：
A. chlorosulfonated polyethylene emulsion, deionized water, dodecyl sodium sulfate are put into emulsifier, primary emulsion is prepared into, 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, mica powder and ammonium bicarbonate soln, lanthanum Ion and ammonium hydrogen carbonate act on forming precipitation, attach on talcum powder and mica powder, synthesizing rare-earth carbonate precursor, pass through After filter, washing, dry, calcination, rare-earth additive is obtained；
C. step b gained rare-earth additives and titanium dioxide, silica flour, silica white, electrically conductive graphite, deionized water are mixed, adds water Property epoxy resin, polyacrylic acid, then on grinder grind, be obtained granularity<30 μm of mill base；
D. step c gained mill bases are mixed with step a gained chlorosulfonated polyethylene latexes, adds silane coupler KH560, adopted Magnetic stirrer 6-10h is used, coating is uniformly dispersed as far as possible, obtain final product the modified hydrophilic chlorosulfonated polyethylene of rare-earth additive Anticorrosive paint.
Rare earth modified hydrophilic chlorosulfonated polyethylene anticorrosive paint of described a kind of low-shrinkage and preparation method thereof, it is special Levy and be, emulsification times are 10-30min in step a.
The beneficial effects of the invention are as follows：Rare-earth complex has stronger ligand complex function, big with chlorosulfonated polyethylene Chlorosulfonyl group reaction generation cross-bond on strand, 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 dry；By talcum powder with it is dilute Earth compounds are combined, and improve wearability, the glossiness of coating；Static conductive graphite is added in coating, there is coating excellent Static conductive, anti-electromagnetic interference performance, the coating for obtaining be applied to various equipment protective coating；By adding silica flour etc., Reduce the shrinkage factor of coating.
