Description
The present invention relates to a kind of natural gulf red priming paint with rust and preparation method thereof.
According to " Chinese chemical goods complete works) " and paint trade information as can be known both at home and abroad, now do not adopt natural iron oxide red production paint, and all be to adopt dry method, wet method and nitrate method production red iron oxide, be raw material then with the red iron oxide, add macromolecule resin and multiple auxiliary is made, and complex manufacturing technology.The various Synolac of the many employings of macromolecule resin are added multiple compositions such as anti-skinning agent.As following compound method and the raw material of listing several iron oxide red primers.
1, C06-2 iron red alcohol acid primer for rusty surface
Raw materials used and preparation: medium oil alkyd, the raw material that surely becomes rusty, pigment, filler, siccative, No. 200 varnish makers' and painters' naphtha, dimethylbenzene.
2, C06-19 iron red alcohol acid primer for rusty surface.
Raw materials used and preparation: long-oil-length pentacite, surely become rusty raw material, pigment, siccative, No. 200 varnish makers' and painters' naphtha, dimethylbenzene.
3, C06-18 iron red alcohol acid primer for rusty surface
Raw materials used and preparation: Synolac addingizations rust raw material, surely become rusty pigment, solvent etc. are concocted through grinding and are formed.
As from the foregoing, this type of paint has following characteristics: except that with Synolac, solvent, the iron oxide red, need add various steady rust former states in addition, change rust raw material, siccative, paint solvent wet goods.And need in reactor, heat and boil resin, again through sequence of operations such as coolings, this all brings difficulty for undoubtedly cost, technology, operation.Although these alcohol acid rust-having priming paint all have superperformance and purposes widely, there are various shortcomings.Slow as raw material complexity, cost height, paint dryness, can not polish, weathering resistance is poor, uvioresistant not, poor adhesive force, not anti-tanning by the sun, easily efflorescence, aging, coating is many, take manually the manufacturing process complexity.
Natural gulf red priming paint with rust of the present invention, purpose provide a kind of not oxidation of surface, do not lump for a long time, and the cost cost is low, particularly save derusting process, the natural iron oxide red priming paint of band rust brushing.Just the qualification result that has passed through is at present seen, the various shortcomings of having avoided above-mentioned red iron oxide alkyd primer manufacturing basically and having used, and this can find out from following several respects:
At first, the present invention adopts natural iron oxide red, after grinding to form the fineness that needs, makes its effect with pigment and filler, has guaranteed the ferric oxide stable components, does not change.Owing to do not add other fillers, can further increase natural iron oxide red ratio, saved many raw materials.Natural iron oxide red reserves are big, are easy to get, and processing is simple, and contaminative is little, has removed loaded down with trivial details, the complicated technology of production red iron oxide from, and cost is low.And natural iron oxide red water insoluble, alkaline-resisting, salt, acid have shielding property, can stop behind the surface oxidation further to the deep layer oxidation, and natural iron oxide red in addition composition is fixing also to be a big advantage.

Secondly, used polymeric resin is chlorosulfonated polyethylene, polystyrene, and solvent is dimethylbenzene or benzene, toluene.
Chlorosulfonated polyethylene: being poly derivative, is polyethylene after chlorination and sulfonation are handled, and the regularity of its structure is destroyed, and becomes soft at normal temperatures and resilient chlorosulfonated polyethylene rubber.It is that a kind of intensity is low, sticking polymkeric substance, and proportion is about 1.1, is soluble in aromatic hydrocarbon and hydrochloric ether; has excellent anti-ozonize performance, its resistance toheat, chemical resistance; resistance to flame is all fine, and wear resistance and lower temperature resistance are good, the protection crust of making coatings.
Polystyrene: be water white transparency, tasteless solid particulate, proportion 1.057-1.070, easy dyeing can burn, water tolerance and dielectric properties excellence, ability organic acid, alkali, salt are dissolved in aromatic hydrocarbon etc.This thing can also reclaim industrial waste, turns waste into wealth, and reduces cost.
In a word, the present invention has raw material sources abundant, economical, is easy to get, and technology is simple, and equipment requirements is uncomplicated, and the priming paint of producing has the unexistent advantage of domestic and international various priming paint, has avoided all shortcomings of existing priming paint again, and especially the brushing of band rust more takes effect.At present, the check and the evaluation of Jilin Province's product quality supervision and testing institute have been passed through.
Mechanism of the present invention:
According to electrochemistry knowledge as can be known, to get rusty be a kind of galvanic corrosion to iron and steel.The complicated component of formed iron rust is generally with Fe
2O
3XH
2O shows that its structure is inner loose duct.
In general, existing coating all is to coat one or more layers coating at steel surface, work the covering effect that is mainly, act on single unavoidably.Have good workability as phthalic resin coating, paint film adhesion is strong.But the paint film softness is water-fast, alkali resistance is poor.Used Synolac generally reacts under special conditions with polyvalent alcohol and Vegetable oil lipoprotein, and the gained superpolymer is netted polyester, only in the metal products shaded surface, works preventing the further corrosive nature of metal.
But, if the superpolymer that generates has this a kind of covering effect merely, then make the easy skinning of coating unavoidably, the result of peeling off.
And natural gulf red priming paint with rust of the present invention is made priming paint in order to be coated with brush rust iron and steel, exactly the mechanism of getting rusty at iron and steel and proposed to be different from existing technology of producing iron alcohol acid rust-having priming paint.It hot iron is red to have and the similar composition of iron rust, and is the mineral of spontaneous growth, ingredient stability, the influence that acid and alkali, alkali, salt change.Can infer, two kinds of superpolymer selecting (or multipolymer of polymer reaction generation), not only can be coated with the last layer paint film at the steel surface that gets rusty, and the mixture formed of the superpolymer that is generated and iron oxide red particle can fill up or see through the duct of iron rust, iron rust and iron oxide red pigment and iron oxide red and the unrusted iron of iron rust deep layer well " bonding " be in the same place, in other words, because iron rust loose and porous inner surface, can hold the mixture that the natural iron oxide red and superpolymer of analog structure is arranged with it well, form very firm and tack-free film.This be because:
At first, two kinds of superpolymer form, and have improved single Properties of Polymer, except can being bonded together well, have also strengthened the adhesive capacity with iron rust, natural iron oxide red and unrusted iron.In other words, formedly be dissolved with natural iron oxide red particulate macromolecular solution and can fill up the inner duct of iron rust well, this high polymeric solution can be penetrated into the inner and unrusted iron surface of iron rust, and the superpolymer of formation can be brought natural iron oxide red particle into iron rust inside with the colloidal state.Like this, between two-phase superpolymer and iron rust, day red and unrusted iron of hot iron, produced the graft copolymer of two kinds of polymkeric substance that can mix with the two-phase superpolymer.
This graft copolymer has specific function.As chlorosulfonated polyethylene and polystyrene originally for not dissolving each other, but when formation is the coating of solvent with dimethylbenzene. just produced the graft copolymer that is connected to polystyrene on the chlorosulfonated polyethylene, after mixing is coated on the band rust iron and steel, this graft copolymer is between several phases, the chlorosulfonated polyethylene chain that is produced in stretching into chlorosulfonated polyethylene, can also stretch into iron rust or natural iron oxide red in or unrusted iron surface, its polystyrene branch in stretching into polystyrene, can also stretch into iron rust or steel surface and natural iron oxide red surface.Like this, except the characteristics of formation multipolymer, also between several phases, with this graft copolymer is media, for " tackiness agent " iron rust, natural iron oxide red and lump together very tight being close to of not getting rusty, form a kind of special, very firm, be different from the formed paint film of single superpolymer, the paint paint film that this paint film is different from the past.
In addition, between two kinds of superpolymer, except forming the graft copolymerization beyond the region of objective existence, can analyze according to the iron and steel rusting mechanism and under conditions suitable, to produce a kind of chain copolymerization of radical that is called between two kinds of polymkeric substance, formed multipolymer also has good corrosion resistance.
In addition, owing to selected chlorosulfonated polyethylene, two kinds of monomers of polystyrene, because the cause of conjugative effect; Can form stable Ji complex compound.
The formation of this Ji complex compound further makes copolyreaction be easy to carry out again, and two kinds of polymer monomers polarity difference are bigger, can attract each other, and get alternating copolymer.
These a series of factors can be explained principle of the present invention.
Method of the present invention and step:
After chlorosulfonated polyethylene, polystyrene made dissolution with solvents with dimethylbenzene respectively, mixing by a certain percentage and adding natural iron oxide red ferric oxide content was more than 70%, and fineness is at other raw materials such as 325-400 orders, and the materials ratio is as follows:
Chlorosulfonated polyethylene 5.1%-7%
Polystyrene 12.1%-13%
Natural iron oxide red 19.1-22%
Benzene,toluene,xylene 63.7%-58%
Wherein, the per-cent of the use of solvent is owing to consider the sliminess of made paint on earth with height, has promptly increased polymkeric substance and natural iron oxide red composition, must reduce the consumption of solvent.Could guarantee the performance of made paint like this.
Other adds talcous composition is 1-3%, is performances such as the brightness that can improve paint, color and luster.
With No. 200 solvent oil 20-35% can corresponding minimizing benzene,toluene,xylene consumption.
Making processes is as follows:
(benzene,toluene,xylene all can with proper amount of solvent earlier, three kinds mix mutually also can) the dissolved chlorine sulfonated polyethylene, stir while feeding in raw material, get an ivory-white stringy liquid, about about 6 hours of time, with the dissolution with solvents polystyrene, get a colloidal liquid again, two kinds of mixed liquid phases are mixed, under constantly stirring, add natural iron oxide red other raw materials that waits in proportion then, get a viscous liquid, no exothermic phenomenon produces a large amount of bubbles, continue to stir, promptly get product, placed about 15 minutes, can use.
The process skeleton diagram as shown in drawings.
The gained natural gulf red priming paint with rust has fast drying, easily polishing, good weatherability, strong adhesion, radiation proof, acid and alkali resistance, salt, water, and anti-tanning by the sun is difficult for efflorescence, do not come off, and nondiscolouring only is coated with one deck, no skinning, nothing caking. To see on the technology, alcohol acid rust-having priming paint compared in the past, and the present invention also has remarkable advantage, and is simple such as technology, easily grasp, not high to equipment requirement, do not need anti-high pressure, high temperature resistance, antiacid, alkali equipment, under normal temperature, the normal pressure, in the situation of mixer and sand mill existence, can drop into batch production, removed paint need to boil, cool off resin in reactor the process of producing from, saved the energy, reduced consuming.
