Abstract
The invention discloses anti-corrosion antirust powder paint belonging to the technical field of powder paint of electrostatic coatings. The anti-corrosion antirust powder paint is prepared by the following common raw materials of powder paint in general proportion: epoxy resin, indoor polyester resin, 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 percent and 0-10 percent of the gross weight of the raw materials. The anti-corrosion antirust powder paint does not contain toxic raw materials limited to use, is suitable for the surfaces ofsteel and iron components treated in various pretreatment modes, and has favorable anti-corrosion antirust performance of the coatings, lower product cost than zinc-based heavy-duty anticorrosive pow der paint, favorable performance price ratio and remarkable economic and social benefits.
Description
Technical field
The present invention relates to a kind of anti-corrosion antirust powder paint, belong to the powder coating technical field of electrostatic coating.
Background technology
Anti-corrosion antirust powder paint is one of powder coating developing trend; The initial stage anti-corrosive powder paint 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 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
The purpose of this invention is to provide a kind of anti-corrosion antirust powder paint, have the coating antiseptic antirust ability and give prominence to the rush-resisting material environment-protecting asepsis of employing, but wide popularization and application.
The present invention realizes with following technical scheme: a kind of anti-corrosion antirust powder paint; It is made up of powder coating such as epoxy resin, indoor vibrin, 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 the composite iron-titanium powder and the 0-10% zinc flake that account for raw material gross weight 10-40% in the prescription.
Raw material and conventional proportioning that above-mentioned powder coating is commonly used are 25-18% epoxy resin, the indoor vibrin of 25-42%, 0.8-5% flow agent, 0.8-5% flow agent, 0.1-0.4% air release agent, 0.1-2% flexibility agent, 0.0-10.02% flow improver additive and 0-30% filler.
Described composite iron-titanium powder comprises any or the two or more mixture of making a gesture of measuring arbitrarily in WD-A-325, WD-A-500, WD-B-500, WD-B-500II, WD-D-325, WD-D-500, WD-D-800 or the WD-D-1250 model; According to anticorrosion needs, preferred single variety.Produce by Wuxi Wanda Science and Technology Ltd..
Described epoxy resin, indoor vibrin are powder coating specific breed, their the consumption adjustment of commercially available routine and carry out the adjustment of certain limit according to coating performance and product cost needs; Flow agent is GLP504, GLP588, PV88, GLP599 etc., and consumption is confirmed by kind; Air release agent is 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.
The invention has the beneficial effects as follows: do not contain poisonous starting material that 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 good, product cost 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.
Enumerate four embodiment altogether, 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, test result explanation coating has good antiseptic property.
