Description
Technical field
It is more particularly to a kind of modified with environment-friendly type water dispersion acrylic the invention belongs to water-based industrial paint manufacturing technology field
Emulsion is the aqueous antirust paint and its preparation technology that are exclusively used in submerged-arc welding of main film forming matter.
Background technology
The antirust paint substantially oiliness that uses and aqueous two kinds at present.Oily antirust varniss makes the greasy removal of material surface tired
Difficulty, has been rarely employed, and oily antirust varniss is easy to use, cheap, but because having containing nitrite, chromate, heavy metal etc.
Noxious material, serious to atmospheric environment destruction, larger to operating personnel and air harm, country has limited and has used.And common water borne
Metallic anti-rust paint is main component from acrylic resin, is obtained after emulsification, or the acrylic acid tree being made as decentralized medium with ether
Fat is film forming matter, is not water paint truly.
And the anti-flash rusting agent that common water borne antirust paint is used is 179 anti-flash rusting agent, the anti-flash rusting agent of H10, the anti-sudden strains of a muscle of X150
Rust agent etc., it can play anti-rust action to common metal surface as antirust auxiliary agent, but at submerged-arc welding particulate metal still
There is flash rusting phenomenon.
A kind of aqueous antirust paint for being exclusively used in submerged-arc welding that the application is proposed both had had the rust-proof effect of universal metal, and
Have in weld surface rust-proof effect, such as：At submerged arc welding.Reach the paint special of aqueous, environmental protective submerged-arc welding truly.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of aqueous antirust paint for being exclusively used in submerged-arc welding, this is aqueous anti-
Rust paint includes following components in parts by weight：
Wherein, film forming matter is environment-friendly type water dispersion acrylic modified emulsion such as Opel enlightening AC2403 or DSM XK-86
Deng.
Wherein, dispersion moisture agent is enlightening 760W high or Bi Ke chemistry FA600.
Wherein, substrate wetting agents are Bi Ke chemistry 328.
Wherein, defoamer is organosilicon, mineral oil or the polyether substances such as Bi Ke chemistry 024, enlightening 902W, NXZ high.
Wherein, bactericide is isothiazolinone material.
Wherein, multifunctional assistant is ANP-95 or other triethanolamine class materials.
Wherein, color stuffing includes pigment, filler, and the pigment is the one kind or many in titanium dioxide, ferriferous oxide, carbon black
Kind；Described filler is two or more the combination in dicalcium powder, kaolin, talcum powder, mica powder, blanc fixe.
Wherein, antirust filler is ferrotitanium powder, trbasic zinc phosphate, aluminium triphosphate etc. one or more.
Wherein, sagging inhibitor is A200.
Wherein, coalescents are the environment-friendly type coalescents such as sieve ground Asia LS-191, propylene glycol monomethyl ether.
Wherein, the special anti-flash rusting agent of submerged-arc welding is the sub- assorted blue 794SA of ASHLAND.With ASCOTRAN-H14 France A Sike
Enlightening H143:2 compoundings are formed.
And the sub- assorted blue 794SA of ASHLAND are a kind of anti-flash rusting agent of environment-friendly type, certain effect is welded with to submerged arc.Main component：
Molybdate+organic VCI.Molybdate：It is that a kind of inorganic acid inhibitor is mainly used in slowing down acid to Metal Substrate during pickling of metal
The corrosion of body, there is good corrosion mitigating effect during various chemical picklings.Make corrosion of metal rate big under normal use
It is big to reduce, and have the ability that excellent suppressions steel inhales hydrogen in acid cleaning process, it is to avoid there is " hydrogen embrittlement " in steel, while suppression is sour
Fe3+ makes metal not produce pitting corrosion of metal during washing.Organic VCI：Vapour phase inhibitor, also known as volatile rust prevention powder is
Powdered vapour phase inhibitor (Volatile Corrosion Inhibitors') is commonly called as.Rustoper (corrosion terminator) gas
Phase antirusting powder is a kind of water-soluble anti-rust powder, can Wet-dry.It is mainly used in the inside gold at metal depression, hollow or cavity
The anti-corrosion treatment of metal surface.In confined space, using dry volatile rust prevention powder, rust-proof effect is splendid.VCI is through gasification
Afterwards, absorption forms fine and close protection film layer so as to play a part of antirust in metal surface.But the anti-flash rusting effect when being used alone
Fruit is not it is obvious that also having flash rusting phenomenon, and addition is higher.
And ASCOTRAN-H14 France A Sikedi H14 are a kind of universal aqueous solutions of organic salts of environmental protection.Dodged in metal
Rust aspect is superior to traditional anti-flash rusting agent, shows excellent especially at weld bond with welding slag, but still having flash rusting used in submerged-arc welding
Phenomenon.
And it has been investigated that, by 794SA and H14 with specific proportioning (such as 2-4:The ratio of 1-3, preferably 3:2 ratio
Example) compounding can reach at submerged-arc welding and base material is without flash rusting.
Wherein, levelling agent is ROHM AND HAAS 2020 or the modest 455 grade polyurethanes levelling agent of this moral of hamming.
Wherein, the thickener in thickener soln is the polyurethanes materials such as the modest 105A of this moral of hamming.
Present invention also offers the preparation method of the above-mentioned aqueous antirust paint for being exclusively used in submerged-arc welding, comprise the following steps：
(1) grinding distribution：First by dispersion moisture agent, the defoamer for accounting for the total consumption half of defoamer, bactericide and go from
Sub- water is added in dispersion tank, is disperseed 10-30 minutes；By anti-settling agent and water 1:The dispersion tank is added after 6 stirrings, disperses 5-15
Minute；Color stuffing and antirust filler are added, at a high speed dispersion 20-40 minutes；Then the slurry in above-mentioned dispersion tank is added into grinding
Machine, is ground to fineness below 30 microns, and the slurry after the completion of grinding is continued to be put into dispersion tank；
(2) painting：To adding film forming matter in dispersion tank, then slurry pH value is adjusted to 9-11 with multifunctional assistant, so
After be slowly added coalescents, disperse 10-30 minutes；Levelling agent, substrate wetting agents are added afterwards；Then it is submerged-arc welding specialty is anti-
Flash rusting agent is with coalescents with 3:2 weight ratio is pre-dissolved, and adds dispersion tank；Then to adding remaining defoamer in dispersion tank；
Finally with 3:1 weight obtains thickener soln than mixing water and thickener, by thickener soln addition dispersion tank, will divide
The viscosity for dissipating slurry in tank is adjusted to 70-80KU, makes slurry by filter screen, obtains being exclusively used in the aqueous antirust paint of submerged-arc welding.
Present invention is mainly used for antirust at metal submerged-arc welding and protection, with good submerged-arc welding weld bond rust-proof effect, it is
Water-based environmental protection concept has been truly realized by main film forming substance of water-based emulsion.By selected professional rush-resisting material and spy
Fixed flash rusting agent proportioning, the special-purpose aqueous antirust industrial paint for submerged-arc welding is obtained using physics, chemical rust-proof mechanism so that
Long-term flash rusting problem is addressed at metal submerged-arc welding.Resulting antirust paint is that product is unified in bottom surface, is once constructed, you can into
Type.The bottom of traditional paint, face are broken and have separated flash rusting problem at Construction Mode and common antirust paint submerged-arc welding, be to substitute tradition to prevent
The splendid regeneration product of rust paint and common antirust paint.
Antirust paint of the invention has aqueous, environmental protective, and water-fast, salt spray resistance, the advantage of good weatherability, rust-proof effect are strong, have
Good heat endurance, still has good antirust function in the environment of low temperature, high humidity, has accomplished environment-protecting asepsis, tasteless, no
