Abstract
The invention discloses heavy anti-corrosion antirust powder paint belonging to the technical field of powder paint. The heavy anti-corrosion antirust powder paint is prepared by the following common raw materials of powder paint in general proportion: epoxy resin, novolac epoxy resin, a phenol curing agent, a curing accelerator, a flatting agent, a degasifying agent, a flexibilizer, a flow promoter, fillings, and the like. The preparation method is carried out by adopting the prior powder paint production technology, and the formulation comprises composite iron-titanium powder and sheet zinc powder which are respectively 10-40 and 0-10 of the formulation according to the parts by weight. The heavy anti-corrosion antirust powder paint does not contain toxic raw materials nationally limitedto use, is suitable for the surfaces of steel and iron components treated in various pretreatment modes, and has prominent anti-corrosion antirust performance of the coatings, lower product cost than zinc-base heavy antisepsis powder paint, favorable performance price ratio and remarkable economic and social benefits.
Description
Technical field
The present invention relates to a kind of heavy anti-corrosion antirust powder paint, belong to the powder coating technical field of electrostatic coating.
Background technology
Heavy anti-corrosion antirust powder paint is one of powder coating developing trend; The initial stage double antiseptic powder coating mainly improves the anti-corrosion capability of powder coating through binder resin, the antirust color stuffing of use; Then take during higher requirement for anticorrosion thickly to be coated with, the constructional method of overbrushing layer or compound coating; Realize the anticorrosion purpose of weight of coating, rust-stabilising pigment commonly used mainly is red lead, zinc powder and aluminium triphosphate.Along with the reinforcement of social enviroment protection consciousness, red lead is limited to use because of the high social danger of lead tolerance greatly gradually, and the paint that contains the red lead composition is also by strict limit production and use, and the application of red lead in powder coating also is difficult to carry out.
The zinc powder processing technology is fast-developing at present; Many enterprises have produced flake zinc powder both at home and abroad; Compare with traditional ball-type zinc powder, flake zinc powder has good shielding, parallel overlap joint performance, electrical contact performance, is prone to the characteristic of suspension, and the powder coating that Chinese patent CN100341965C adopts flake zinc powder to process has also obtained industrial application; But the zinc flake selling at exorbitant prices also makes the application of Zinc-based double antiseptic powder coating be restricted.
People have developed rust-stabilising pigments such as aluminium triphosphate and phospho-molybdic acid zinc calcium to replace red lead, though practical application obtains certain protection effect, antiseptic power does not reach the effect of using red lead always.
Chinese patent CN101033364 has reduced the consumption of flake zinc powder through the fit applications of flake zinc powder and rust-stabilising pigment, nano material, reduces cost, and guarantees that also zinc content is safeguarded workmen's health in the dry film below safety standards; But its rust-stabilising pigment that adopts is kinds such as red lead, zn phosphate, and its application is subject to significant restrictions.
Summary of the invention
It is outstanding to the purpose of this invention is to provide a kind of coating antiseptic antirust ability, the rush-resisting material environment-protecting asepsis of employing, but the heavy anti-corrosion antirust powder paint of wide popularization and application.
The present invention realizes with following technical scheme:
A kind of heavy anti-corrosion antirust powder paint; It is made up of powder coating such as epoxy resin, novolac epoxy, phenols curing agent, curing catalyst, flow agent, air release agent, flexibility agent, flow improver additive and filler raw material and conventional proportioning commonly used; The preparation method adopts existing powder coating production technique to carry out, and contains in the prescription to account for formulation weight part 10-40% composite iron-titanium powder and 0-10% zinc flake.
Described composite iron-titanium powder comprises any or two kinds of WD-A-325, WD-A-500, WD-B-500, WD-B-500II, WD-D-325, WD-D-500, WD-D-800 and WD-D-1250 model and two or more arbitrarily than mixture; According to anticorrosion needs, preferred single variety (producing) by Wuxi Wanda Science and Technology Ltd..
Raw material and conventional proportioning that above-mentioned powder coating is commonly used are 25-30% epoxy resin, 10-20% novolac epoxy, 8-20% phenols curing agent, 0.5-1% curing catalyst, 0.8-5% flow agent, 0.1-0.4% air release agent, 0.1-2% flexibility agent, 0.01-0.02% flow improver additive and 0-30% filler.
Described epoxy resin is that GT-7255, phenols curing agent are PSG-01 for conventional E-12, novolac epoxy, and their consumption adjustment is carried out the adjustment of certain limit according to coating performance and product cost needs; Flow agent is GLP503, GLP588, PV88, GLP599 etc., and consumption is confirmed by kind; Curing catalyst is that Methylimidazole, air release agent are that st-yrax or micro mist wax, flexibility agent are that butyral (PVB), flow improver additive are aerosil or aluminum oxide C; Filler is powder coating such as all kinds of permanent white, lime carbonate, tiff kinds commonly used; Zinc flake also is commercially available flake zinc powder product.
The composite iron-titanium powder product series is the novel antirust pigment that adopts the alternative red lead powder of nanotechnology development; This rust-stabilising pigment, particularly s-generation product WD-D type composite iron-titanium powder, rust-preventing characteristic, weathering resistance all are superior to red lead powder; Price is lower than red lead powder; The heavy metal total content is below 2/10000ths, and it is little, of light color to have density, numerous good characteristics such as be prone to disperse, not stratified during use.Produce and sell by Wuxi Wanda Science and Technology Ltd..
The invention has the beneficial effects as follows: do not contain poisonous starting material that country restriction uses in the product, be applicable to that steel and iron member surface, coating antiseptic antirust ability that various pre-treatment modes handle are outstanding, product cost also is lower than Zinc-based double antiseptic powder coating; Has good cost performance, economy and obvious social benefit.
Embodiment
Further illustrate scheme of the present invention and effect below in conjunction with embodiment.
Each Example formulations and effect are seen table 1.After various raw materials are taken by weighing by proportioning, in the high speed mixing tank, mix broken evenly after, extrude, get product after broken, the abrasive dust screening.Product of the present invention is sprayed on the iron and steel parts after the surface treatment coat-thickness 60-90 μ m.
