Description
Technical field
A kind of aqueous rust-conversion rust-inhibiting primer, belongs to water paint product technical field.
Background technology
Water paint product, along with the development of technology, is also increasingly suitable for the use in market in properties of product.The accreditation in market is had been obtained in a lot of fields, aqueous materials technology and formula technique are perfect gradually, water paint kind is more and more various, partial properties is progressively caught up with and has even been caught up with and surpassed solvent based product, and wherein aqueous architectural decorative paint (emulsion paint), aqueous woodware paint, waterborne metallic paint, aqueous glass paint, aqueous plastic coating, water-based anticorrosive paint, aqueous automobile paint etc. are all flourish.Such as other water paint, the development of aqueous antirust paint is also in initial stage.The aqueous woodware paint the most earnest in recent years compared to coating producer, aqueous antirust paint has bigger development potentiality.Only from the market share, aqueous woodware paint accounts for about the 17% of China's Coating Market gross sales amount, and the ratio of protective coating reaches about 21%.
Aqueous antirust paint, with water for diluent, must polish off rust face, virgin metal surface could use in use, and otherwise water can remain on rust face, can not form good combination in the dry run of antirust paint.Not only do not have antirust effect, also can expand rust face at this place further, accelerate metal erosion.And advanced rust face, row metal surface polishing before use can increase substantial amounts of human and material resources consumption, lengthen working hours.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, it is provided that a kind of easy to use, simple aqueous rust-conversion rust-inhibiting primer of operation.
The technical solution adopted for the present invention to solve the technical problems is: this aqueous rust-conversion rust-inhibiting primer, it is characterized in that, concrete weight portion consists of: aqueous rust transforming agent 40 ~ 50 parts, cation-modified emulsion 30 ~ 40 parts, stabilizer 1 ~ 3 part, defoamer 1 ~ 3 part, thickening agent 1 ~ 10 part, deionized water 10 ~ 20 parts.
The priming paint of the present invention is that a kind of aqueous rust converts paint, by aqueous rust transforming agent and metal surface rust generation chemical reaction, makes rust iron sesquioxide (Fe2O3) it is reduced to ferrum (Fe), molten with steel substrate it is integrated, and then is converted into alloy paint film with metals such as calcium, manganese, zinc, chromium or nickel in iron and steel.Paint film adhesion reaches one-level, and its adhesive force effect exceedes 2 grades of adhesive force that general anti-corrosive primer reaches, and antirust ability also substantially exceeds the national standard of the anti-corrosive primers such as conventional alkyd iron oxide red, phenolic aldehyde iron oxide red.When indoor use, direct spraying can reach optimum efficiency, it is possible to saves priming paint, middle paint, finish paint, be substantially reduced antirust cost.Reduce labor intensity and working time simultaneously.
Preferably, described weight portion consists of: aqueous rust transforming agent 45 parts, cation-modified emulsion 35 parts, stabilizer 2 ~ 2.5 parts, defoamer 2 ~ 2.3 parts, thickening agent 6 ~ 8 parts, deionized water 15 ~ 18 parts.Under this optimum condition, priming paint adhesive force and antirust degree reach the best.
Described aqueous rust transforming agent is organic phosphate, it is preferable that (molecular formula is NaAl to acid aluminum phosphate sodium3H14(PO4)8·4H2O).Acid aluminum phosphate sodium can make the rust oxide of iron and steel be converted into the organoiron compound of black, thus generating one layer by the complexes membrane of chemical bond and physical bond at steel surface.The harm of the original rust not only eliminated, also as the formation of this layer of complexes membrane further enhancing antirust ability and paint film adhesion.
Preferably, described cation-modified emulsion is vinyl chloride-vinylidene chloride copolymer emulsion (molecular formula (C2H3Cl)m(C2H2Cl2) n) or the acrylic emulsion of pH value 2 ~ 4.It is a kind of novel high polymer synthetic latex that vinyl chloride-vinylidene chloride copolymer emulsion converts cation-modified emulsion as rust, nontoxic, odorless, do not fire, constructing on slightly moisture substrate, filming performance is excellent, and after conjunctiva densification, film forming, air penetrability is significantly less than oil paint, generic latex paint.
Acid aluminum phosphate sodium aqueous rust transforming agent selected in the present invention and the key technology that weight ratio is the present invention of the cation-modified emulsion of vinyl chloride-vinylidene chloride copolymerization.Under this proportioning, acid aluminum phosphate sodium aqueous rust transforming agent to lacquer painting formation time of the infiltration of rust and transformation efficiency with the cation-modified emulsion of vinyl chloride-vinylidene chloride copolymerization can be just right coordinate.Avoid the substance reaction in particle and the air that the activity produced in the chemical reaction process of rust transformation strengthens, and in reasonable time, alloy paint film can be converted into the metal such as the calcium in iron and steel, manganese, zinc, chromium or nickel.
Preferably, the vinyl chloride-vinylidene chloride copolymer emulsion density when 20 DEG C is 1.2137g/cm3。
Preferably, described stabilizer is isomery alcohol polyoxyethylene poly-oxygen propylene aether, molecular formula C [CH2O(C2H4O)n(C3H6O)mH]4.The selection of this stabilizer is a kind of nonionic surfactant.Good with various surfactants, auxiliary agent, additive, solvent compatibility, acidproof, alkaline-resisting, antioxidation.Especially in the present invention select aqueous rust transforming agent and cation-modified emulsion compatibility is good, compatibility is strong, be uniformly dispersed in primers, can better maintain the reactivity of aqueous rust transforming agent and cation-modified emulsion, expanded service life.
Preferably, described defoamer is without silicon defoaming agent.Defoamer can make in the water-based system of this priming paint froth breaking and press down bubble effectively.
Preferably, described thickening agent is polyurethane associative thickener.Environment, using water as disperse medium, is not produced harmful effect, is the Environmentally-friepolymer polymer material of standard by selected polyurethane associative thickener.The rheologic behavio(u)r that water base high molecular material has self not necessarily meets the requirement of application, rheology auxiliary agent need to be added during most water base high molecular materials'use, viscosity such as macromolecule emulsion is most and pure water is close, needing to add thickening agent when using as coating and improve system viscosity, thickening agent is most widely used rheology auxiliary agent in water base high molecular system.
Compared with prior art, the had the beneficial effect that present invention of aqueous rust-conversion rust-inhibiting primer of the present invention is prepared for a kind of faintly acid polymer composite type anti-corrosive primer, the oxide (rust) that can make iron and steel is converted into black simple substance or organoiron compound, thus generating one layer by the complexes membrane of chemical bond and physical bond at steel surface, therefore rete firmly fine and close, adhesive force is extremely strong, makes steel substrate and dielectric separates be no longer influenced by corroding.This anti-corrosive primer can form very thin protective layer, therefore can be used for precise part and the antirust treatment on moving component surface, and does not affect its precision and proper motion.This anti-corrosive primer is the acidic group formula of a kind of uniqueness, can penetrate into rapidly and fully the place of corrosion, by rust transformation.This anti-corrosive primer is aqueous harmful material such as not containing benezene, formaldehyde etc., and non-volatility gas produces.Use that this anti-corrosive primer technique is more laborsaving than common process, save time, work efficiency is high, integrated cost is low.
