Abstract
The invention discloses a special anti-corrosion rust-proof paint with rust removal. The paint comprises the components by weight: 21 to 29 percent of epoxy complex acid-propylene modified resin, 13 to 19 percent of epoxy saturated resin, 38.5 to 44.5 percent of mixed rust-proof pigment, 0.3 percent of addition agent, 16 percent of mixed solvent, 0.5 percent of leveling oil resistance agent and 0.7 percent of anti-settling agent. The paint is prepared from the epoxy modified resin with complex acid, a cashew nut oil curing agent, red iron oxide, zinc oxide, a solvent, the addition agent, and the like. The paint prepared in proportion is sprayed or brushed on a rusty iron piece. The paint with excellent penetrability permeates into the bottom of an oxide layer. A generated paint film has the advantages of high density, good hardness and strong wearing resistance and impact force resistance. Therefore, the special anti-corrosion rust-proof paint with rust removal completely eliminates the secondary contact of new iron with the moisture and oxygen of the outside world, and eliminates the possibility of secondary rust fundamentally.
Description
Technical field
The present invention relates to a kind of coating, specifically is a kind of special anti-corrosion rust-proof paint with rust removal, in addition, the invention still further relates to the preparation method of this coating.
Background technology
Existing metal protective coating is rust-inhibiting paint substantially, below is conventional rust-inhibiting paint correlation technique parameter:
Viscosity (coating-4 viscosity meter) is not less than 50 seconds, and fineness is not less than 60um, is not less than 24 hours time of drying, and hardness is not less than 0.40, and shock resistance is not less than 50kg/cm, 1 grade of sticking power, and resistance to salt water 48h is non-foaming, non-corrosive, nitrocellulose lacquer resistance is good.
The antirust principle of conventional rust-inhibiting paint is: at first steel surface is carried out pre-treatment, the floating rust of steel surface or zone of oxidation are removed after overpickling, phosphatization or sandblast, polishing substantially, just carry out the processing of rust-inhibiting paint brushing then.This antirust process is just utilized rust proof paint to intercept airborne moisture content and oxygen and iron and is reacted, thereby reach the process that prevents that secondary from getting rusty, but in fact, floating rust can be removed, zone of oxidation just can't be removed, what all have nubbin to exist, and the easy secondary of this just conventional rust-inhibiting paint returns the reason place of rust.
According to the actual service condition of domestic conventional antirust, anti-corrosive for many years, existing rust-inhibiting paint can not satisfy maintenance, the maintenance needs of the antirust, anti-corrosive of a lot of main equipments and military project; And for antirust, need before the rust-inhibiting paint brushing, carry out pickling, parkerizing process, the severe contamination that the acid washing phosphorization liquid of generation can bring environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of favorable rust preventing effect, need not to do processing of rust removing before the brushing construction, also has special anti-corrosion rust-proof paint with rust removal acidproof, alkaline-resisting, the oil resistant characteristic simultaneously.
Special anti-corrosion rust-proof paint with rust removal of the present invention is characterized in that comprising following component and content (weight):
Acid third rare modified resin 21-29% is closed in the epoxy Lip river
Epoxy saturated resin 13-19%
Mix rust-stabilising pigment 38.5-44.5%
Auxiliary agent 0.3%
Mixed solvent 16%
Levelling oil-repellent 0.5%
Anti-heavy agent 0.7%.
Mixing rust-stabilising pigment wherein comprises following component and content (weight):
The high ferric oxide red powder 35-41% that forges
1000 order zinc oxide 11-15%
Super-fine zinc dust 22-28%
Deposit B as 8-12%
Zinc yellow 12-16%.
Mixed solvent comprises following component and content (weight ratio):
Toluene 70%
Butanols 10%
Butyl ether 10%
Pimelinketone 10%.
Described auxiliary agent is the 160S auxiliary agent.
The preparation method of above-mentioned special anti-corrosion rust-proof paint with rust removal may further comprise the steps:
1) at first mixes rust-stabilising pigment by the said ratio preparation;
2) will mix in the mixed solvent that rust-stabilising pigment adds 60% said ratio and soak, add 0.3% 160S auxiliary agent simultaneously,
3) acid third rare modified resin is closed and the epoxy saturated resin carries out high speed dispersion in the epoxy Lip river that adds the 60-80% said ratio after 1-2 hour,
3) carry out sand milling technology again after being uniformly dispersed, in fineness control criterion scope;
4) mixed slurry that sand milling is good closes acid third rare modified resin and epoxy saturated resin and 40% mixed solvent with remaining 20-40% epoxy Lip river in proportion, and levelling oil-repellent, anti-heavy agent add, and stirs;
5) paint is transferred to the required viscosity of standard;
6) check, packing.
The present invention is by band complex acid (that is: complex acid, H
2[PtCl
6]) epoxy modified resin, the cashew nut oil solidifying agent, red iron oxide, zinc oxide, solvent, auxiliary agents etc. are formulated.The coating for preparing is in proportion spraying or is brushing on the ironware that gets rusty, this coating relies on it self fabulous seepage force, be penetrated into the zone of oxidation bottommost always. promptly: new iron and the floating separate layer that becomes rusty, then floating rust or zone of oxidation are wrapped, the complex acid of this moment will play coordination reaction (not reacting substantially with burnt ferric oxide) with the rust iron of oxidation, complex reaction just generates complexing ion salt.Complexing ion is synthetic with the coordinate bond reaction with ligand by central ion, is a kind of more stable complicated ions.(when forming ion, central ion provides unoccupied orbital, and ligand provides lone-pair electron), and Fe3+, Fe2+ is a transition element ion common during complex compound forms.In this process, complex acid just changes into needed pigment salt in the paint to ferric oxide.Meanwhile, resin and solidifying agent are also playing crosslinking reaction, and this reaction is a kind of polymer, the strong crosslinked building-up reactions of density.The paint film that generates has the density height, and hardness is good, and the wear resistance impact resistance is extremely strong, has therefore stopped new iron and extraneous moisture content fully, and the possibility that secondary gets rusty has also just fundamentally been stopped in the secondary contact of oxygen.
The time of drying of this coating is slow, surface drying is about one hour, do solid work about 48 hours, complete reaction is a week. this lacquer paint film is except that the advantage of mentioning above, sticking power is also fabulous. and its antiseptic property is also good especially, excellent water-oil resistance is arranged, acid-fast alkali-proof, the characteristic of the anti-strong solvent of salt spray resistance.
Special anti-corrosion rust-proof paint with rust removal of the present invention, its product parameters is: viscosity (coating-4 viscosity meter) is not less than 50 seconds, fineness is not more than 60um, be not more than 48 hours time of drying, hardness is not less than 0.55, and shock resistance is not less than 50kg/cm, 1 grade of sticking power, resistance to salt water 750 hours is non-foaming, non-corrosive, and nitrocellulose lacquer resistance is good.Its basic data was removed except time of drying, all surpassed existing rust-inhibiting paint, because conventional products is the gas drying, and the present invention is a polymer cross-linking chemistry reacting drying, so time of drying is longer.The hardness of product of the present invention is not less than 0.55,750 hours non-foaming non-corrosives of resistance to salt water, and nitrocellulose lacquer resistance is superpower, also has acidproof, alkaline-resisting, grease-proof characteristic simultaneously, is that general protective system is incomparable.And present coating of the present invention can brush construction under the situation of not doing processing of rust removing, the derusting anti-corrosive effect be conventional antirustization 5-10 doubly, the salt spray resistance of conventional rust-inhibiting paint is tested has only 75 hours.The salt spray resistance experiment of this product can reach more than 750 hours.
