Abstract
The present invention relates to static conductive powder paint which is compounded from 55 to 65 wt% of polyester resin, epoxy resin or polyurethane resin, 27 to 40 wt% of filler, 4 to 5 wt% of levelling agent and 3 to 4 wt% of solidifying agent. The present invention is characterized in that the paint also contains 0.15 to 20 wt% of conductive particulate medium, and the medium can be prepared from one kind or the mixture of two kinds of graphite, acetylene black and zinc oxide. The paint can make a film forming layer have antistatic performance on the basis of the guarantee of wear resistance and corrosion resistance. The paint is especially suitable for electrostatic resistance and corrosion resistance for surfaces in the petroleum industry, the chemical industry and the electronic industry.
Description
The present invention relates to a kind of body surface electrostatic that can prevent and lead the static powder coating.
Common static powder coating generally adopts vibrin, Resins, epoxy urethane resin as the film forming matrix, is being equipped with wear-and corrosion-resistant filler, tinting material, flow agent, solidifying agent, matting agent, toughner etc.By electrostatic power unit, utilize it to radiate 25～65KV static voltage, charged powder particle is coated on workpiece surface, form the corrosion-resistant protective layer of insulation.But consider that from the industrial safety aspect abrasion-proof corrosion-proof layer that above-mentioned static powder coating forms does not have electrostatic conductive performance,, can cause fearful blast because of the poly-attached a large amount of static charge of film formation surface in some inflammable and explosive occasions.Therefore,, spray the occasion of above-mentioned static powder, need carry out antistatic treatment, the film forming matrix is had on the good abrasion-proof corrosion-proof performance basis, possess eliminating layer surface electrostatic function powder for needs from security standpoint.
CN88106888.8 has introduced a kind of plastic static coating conductive agent, this conductive agent mainly is applicable in the electrostatic coating with low polar high crystalline plastics as primary coat, to form one deck conducting film, improve electrostatic coating usefulness such as surface of plastic products.Its goal of the invention and the present invention have essential distinction.
As the conducting paint composite that CN89100775.X introduces, said composition is suitable for being applied on non-conducting material and the semiconductor material, makes the antistatic film that is used for electronics and electrotechnics aspect.
Above-mentioned two kinds of conductive agents all are to be used to be coated in the non-conductive medium surface to form conductive coating, be not to be coated on metal material surface as antistatic layer, and above-mentioned conductive agent abrasion-proof corrosion-proof performance also can not show a candle to existing common static powder, therefore, its material composition and purposes aspect and the present invention are also inequality.
The object of the present invention is to provide a kind of wear resistant corrosion resistant to lead the static powder coating, this powder coating is to form on the basis at existing common static powder coating, with addition of some conducting medium particle, makes the film forming matrix of its formation can eliminate the static that the surface forms.
A kind of static powder coating of leading, comprise that the urethane resin vibrin or the Resins, epoxy that account for gross weight about 55～65% makes the film forming base-material, be equipped with 27～40% wear resistant corrosion resistant filler again, 4～5% solid flow agent, 3～4% solidifying agent material deliverings also contain the electrically conductive particles medium that accounts for gross weight 0.15～20% in the above-mentioned powder coating component.This conducting medium can adopt graphite, acetylene black, zinc oxide etc., and each conducting medium can Individual existence, also can adopt two or more conducting medium combination collocation to use.Filler of the present invention can adopt titanium dioxide, barium sulfate, zinc sulfide white, talcum powder etc.
Above-mentioned conductivity of leading the static powder coating is adjustable, its base-material and one timing of material delivering component content, and the quantity that the electrically conductive particles medium adds is many more, and the conductivity of coating is good more; Vice versa.Can add gross weight 1～5% tinting material for making coating have color.
In order to keep above-mentioned coating to possess the favorable mechanical performance, chemical property and optical property should guarantee to reduce the add-on of electrically conductive particles medium as far as possible under the electrostatic conductive performance prerequisite, usually more satisfactory add-on should be controlled at 0.15～4%, preferably is controlled in 0.15～0.5% scope.
The present invention relatively not only has identical anticorrosion and decorate properties with domestic and international existing common static coating, and main is that the present invention has increased a kind of antistatic property, and the resistivity of leading electrostatic coating can be adjusted according to customer requirements.Electrically conductive particles medium such as graphite, zinc oxide etc. are added in the common static powder in proportion, utilize electrostatic power unit that powder particle is sprayed on workpiece surface.Then; the workpiece that will be coated with is sent in the process furnace again; when intensification is heated to 60 ℃ of left and right sides; resin begins fusing; in fusion process gradually; electrically conductive particles begins to the coatingsurface drift, and forms the conductive network that electrically conductive particles density is concentrated relatively on the coating top layer, and the electrically conductive particles in the top layer is in contact with one another substantially.Although electrically conductive particles changes with temperature and time in heat-processed, constantly float to the top layer, when temperature reached design requirements, the surface of above-mentioned conductive network can form the transparent corrosion prevention film of one deck high-quality again, and this thicknesses of layers is less than below 10 microns.
This product mainly is applicable to oil, chemical industry, electron trade, can avoid or remove static damage, eliminates because of producing the various unsafe factors that static is hidden.The technology of the present invention performance index:
1. powder fineness: the 160-180 order is by 99.5%.
2. paint film appearance: from unglazed to light is arranged, from smooth to wrinkle, mallear stria, class's line, little to big tangerine line etc., have multiple color, texture to analyse clearly.
3. condition of cure: 120 ℃-200 ℃, 3-35 minute.
4. coating thickness: 30-500 micron.
5. gloss: 2%-80%,
6. sticking power: 1-2 level.
7. shock strength: 45-50KY.
8. snappiness: 1-2 millimeter.
9. water tolerance: it is intact to soak 1000 hours paint films.
10. resistance to salt water: 500 hours no changes of 5% sodium chloride solution room temperature.
11. oil-proofness: 20
#It is intact that machine oil soaks 400 hours paint films.
12. acid resistance: it is intact that 5% sulphuric acid soln soaks 240 hours paint films.
13. alkali resistance: it is intact that 5% sodium hydroxide solution soaks 300 hours paint films.
14. resistance value: 10-10
8Ohm.
