Abstract
The interpenetrating-network polymer anticorrosion paint for rusted steel includes component A formed from prepolymer produced by reaction of dehydrated castor oil and toluene diisocyanate, component B formed from epoxy acrylic resin, epoxy resin, phenylethylene, initiating agent and polymerization inhibitor, and component C castor oil pigment colour paste containing accelerating agent and catalyst. The above-mentioned three components are mixed so as to form the invented paint. Said paint can be used for rusted steel, and possesses good anticorrosive property, film-forming property, low toxicity and good decorative property, so that can be extensively used for anticorrosion protection of various steel structures.
Description
The present invention relates to a kind of protective system.
The simplest, the effective means of anti-corrosion of metal are coating protections; at present chlorinated rubber, chlorosulfonated polyethylene, epoxy, protective system such as epoxide coal bituminous have been used widely, but these protective systems generally exist surface treatment requirement height, low, thin, the shortcomings such as anticorrosion ability is not good, ornamental difference of filming of solid part.
But the purpose of this invention is to provide a kind of component capable of coating with rust, whole all film forming, preservative property are good, gloss is high seepage stability type interpenetrating network polymer anti-corrosion paint for rusted steel.
Interpenetrating network polymer anti-corrosion paint for rusted steel comprises the first component of being made up of the prepolymer of synourin oil and tolylene diisocyanate reaction generation, the component B of being made up of epoxy acrylic resin, Resins, epoxy, vinylbenzene, initiator, stopper and the three kinds of components of Viscotrol C dispersible pigment color paste that contain promotor, catalyzer are interpenetrating network polymer anti-corrosion paint for rusted steel with above-mentioned three components by following weight proportion mixing and stirring: first component: component B: mill base=1: 0.7～3: 0.5～2.
The weight percent of first component consists of: tolylene diisocyanate 25～60%, synourin oil 40～75%.
The weight percent of component B consists of epoxy acrylic resin 5～50%, Resins, epoxy 2～45%, vinylbenzene 30～85%, initiator 0.1～3%, stopper 0.01～0.2%.
The weight percent of dispersible pigment color paste consists of: synourin oil 20～70%
Red iron oxide 10～40% zinc phosphates 3～20%
Zinc-chrome yellow 5～25% zinc oxide 5～10%
Talcum powder 5～30% promotor 0.05～1%
Catalyzer 0.05～1.5%
Above-mentioned initiator is benzoyl peroxide or cyclohexanone peroxide.
Above-mentioned stopper is Resorcinol or p-ten.-butylcatechol.
Above-mentioned promotor is N, accelerine or cobalt naphthenate.
Above-mentioned catalyzer is dibutyl tin dilaurate or dimethylethanolamine.
The characteristics of interpenetrating network polymer anti-corrosion paint for rusted steel of the present invention are: one, perviousness is extremely strong and have reactive styrene monomer and will be brought into the iron plate surface of iron rust bottom by its dissolved polyurethane prepolymer, epoxy acrylic resin, Resins, epoxy together, polymerization forms interpenetrating net polymer, with ground iron plate firm attachment, iron rust is surrounded suppresses further corrosion on the other hand on the one hand; Active rust-stabilising pigment can reach the purpose of stablizing corrosion with the heteropolyacid complex compound of iron rust reaction formation indissoluble; The isocyano of polyurethane prepolymer can solidify with micro-moisture reaction in the rusty scale, prevents the further corrosion of moisture content to metal.Therefore this coating has fabulous band rust rust inhibition.Two, epoxy acrylic resin, styrene polymerization form poly-substituted ethylene (pv) network, Resins, epoxy, Viscotrol C form epoxy castor oil type polyurethane (pu) network with the polyurethane prepolymer reaction, rigid pv network and elasticity pu network interpenetration, force mutual appearance effect to produce synergistic effect, make coating have high tensile strength, toughness, wear resistance and hardness.Three, between pv and pu network except that having the IPN effect, the crosslinked action that also has the Raolical polymerizable of the two keys of c=c of the reaction of the hydroxyl of epoxy acrylic resin and isocyano and Viscotrol C and vinylbenzene, epoxy acrylic resin and produce, crosslinked action have strengthened the penetrating power of media such as the compactness of filming and anti-water, solvent, ionogen.Four, all there is the epoxy component in pv and pu two networks, makes coating have the corrosive power of fabulous sticking power and chemical mediators such as excellent acid-and base-resisting, salt.But whole compositions of five, forming coating are film forming all, and volatile organic matter (voc) is few, is coated with thickness, and toxicity is little, is " green coating " that is beneficial to construction, is beneficial to environmental protection.Six, coating film gloss can reach more than 90%, has fabulous ornamentally, not only can make band rust anti-corrosion primer, also can decorate antisepsis finishing paint.
Embodiment 1: 45 kilograms of tolylene diisocyanates are added in the reactor, add 55 kilograms of synourin oils under constantly stirring, controlled temperature is no more than 80 ℃, reacts to obtain the first component in 2～4 hours; 70 kilograms of vinylbenzene are added in the reactor, add 1.9 kilograms of benzoyl peroxides again, 0.1 kilogram of Resorcinol, 18 kilograms of 612-2 epoxy acrylic resins, 10 kilograms of stirring and dissolving of 624 Resins, epoxy are component B fully; 43 kilograms of synourin oils, 25 kilograms of red iron oxides, 12 kilograms of zinc-chrome yellows, 5 kilograms of zinc phosphates, 5 kilograms in zinc oxide, 9 kilograms of talcum powder, N, 0.9 kilogram of accelerine, 0.1 kilogram of mixing and stirring of dibutyl tin dilaurate be ground to fineness qualified mill base.Above-mentioned first component, component B, mill base are interpenetrating network polymer anti-corrosion paint for rusted steel by 1: 1: 0.8 weight ratio mixing and stirring.
Embodiment 2: production technique is with embodiment 1.Its first component consist of 55 kilograms of tolylene diisocyanates; 45 kilograms of synourin oils; Component B consist of 70 kilograms of vinylbenzene, 1.8 kilograms of cyclohexanone peroxides, the time 0.2 kilogram of tert-butyl catechol, 15 kilograms of 612-2 epoxy acrylic resins, 13 kilograms of 601 Resins, epoxy; Mill base consist of 38 kilograms of synourin oils, 26 kilograms of red iron oxides, 12 kilograms of zinc-chrome yellows, 5 kilograms of zinc phosphates, 6 kilograms in zinc oxide, 12 kilograms of talcum powder, 0.8 kilogram of cobalt naphthenate, 0.2 kilogram of dimethylethanolamine.Above-mentioned first component, component B, mill base are interpenetrating network polymer anti-corrosion paint for rusted steel by 1: 1.2: 0.8 weight ratio mixing and stirring.
