The invention provides a steel part high temperature labeled inorganic coating. A binder, white pigment and a dispersant according to the weight ratio of 100: (10 to 30):( 0.1 to 5) are mixed with water and are ball-milled into the coating which is white slurry has the average particle size less than 10 mu m, the solid content 20 to 60 weight percent, and the pH value 5 to 9. The white pigment of the coating can be one or more of titanium dioxide, zinc sulfide, lithopone, barium sulfate and talc; the dispersant of the coating can be one or two of sodium cellulose glycolate and sodium alginate; and the binder of the coating can be low temperature crown glass powder or the mixture of the low temperature crown glass powder and water glass, wherein the low temperature crown glass is prepared from raw materials which are less than 180 meshes, are intensively mixed and sintered for 1 to 3 hours at 600 DEG C and ground into less than or equal to 300 meshes; and the raw materials comprise the following components: 60 to 80 percents of P2O5, 1 to 10 percents of B2O5, 15 to 30 percents of ZnO, and 0 to 5 percents of Na2O.
Description
Technical field:
The invention belongs to a kind of inorganic high-temp and use coating, particularly a kind of high temperature steel member label is used coating, is applicable on steel parts such as steel billet, steel ingot, coil of strip material and makes the data sign.
Background technology:
The high temperature label is to be sprayed on steel piece surface such as steel billet, steel ingot, coiled material or remarkable a kind of labelling method of position, is used for indicating the information such as hearth number, steel grade, production batch, unit of steel part.Its objective is steel part is managed in subsequent handling and follow-up of quality, guarantee that steel have complete performance data, also be used for reviewing simultaneously the problem that former process possibly exist.
Because a plurality of technology matrix surfaces after steel part comes out from process upstream all are under the higher relatively temperature (100-1400 ℃); This moment use coating through spray equipment or hand spray mark need labeled coating can satisfy instantaneous complete adhesion, clear, firmly and as far as possible simplify spraying coating process, be convenient to the operation.Therefore the high temperature labeled coating is had higher requirement.
CN1470570A discloses a kind of " high temperature billet steel sign spray printing coating "; Though can satisfying, this coating at high temperature forms clear, firm sign; But because the peracidity (normal temperature pH value 1-2) of coating self has proposed too high corrosion-resistant requirement to production unit, the packaging vessel of coating; Application process also must adopt special spraying equipment simultaneously, is unfavorable for the promotion and application of this coating.
CN1916085A discloses a kind of " the superphosphate coating that is used for the jet printing symbols in high temperature sign "; This coating has possessed the characteristic that high temperature forms clear firm sign down; Simultaneously also than the disclosed coating of CN1470570A have relatively low acidity ((normal temperature pH value 2-4), its utilization be that polycondensation at high temperature such as acid phosphatase magnalium dehydration polymeric performance realizes spraying adherent effect.But this method is similarly under the acidic conditions; Realize with and steel substrate generation surface chemical reaction following through high temperature; It has proposed requirement to the corrosion resistant performance of equipment equally in preparation and application process, though application method is simple relatively, the fineness of used pigment is less than 1 micron; This has improved the cost of coating greatly in production process, and same being difficult for accepted by market.
Summary of the invention:
The objective of the invention is: a kind of steel part high temperature label inorganic paint is provided; This coating has stable high-temperature performance; Corrodibility is little; The high temperature strong adhesion, existing spraying equipment capable of using, directly on greater than the various steel billets under 100 ℃ of conditions of high temperature, slab, continuously cast bloom, band steel and various steel as the online marking material of high temperature of steel grade, heat (batch) number specification etc.The both numbers of spray by hand of this coating, also can with the supporting use of automatic high temperature jetting device for making number.Solve the difficult problem of online high temperature sign on steel-making, steel rolling, the continuous casting line, promptly eliminated the mixed steel accident that causes because of the sign problem, created condition for hot-loading and hot-conveying again.
The technical scheme that realizes the object of the invention is: a kind of inorganic paint that is used for steel part high temperature label, it contains components such as sticker, dispersion agent, white pigment.Be characterized in that the weight ratio of each component of coating is that sticker, pigment, dispersion agent weight ratio are 100: (10-30): (0.1-5), it is 20-60wt% that water transfers to the coating solid content; The pH value of coating is between 5-9; Select white pigment for use to steel part labeled coating major part, the used white pigment of the present invention comprises one or several in white titanium pigment, zinc sulphide, lithopone, permanent white, the talcum; Said dispersion agent is one or both in Xylo-Mucine, the sodium-alginate.Used sticker be low-temperature lead-free glass powder or with the mixture of water glass, wherein the low-temperature lead-free glass chemistry consists of P
2O
560%-80%: B
2O
51%-10%: ZnO 15%-30%: Na
2O 0%-5%.
The preparation method of low temperature glass who meets chemical constitution in the described sticker is following:
Select particle be narrower than 180 orders by the crown glass powder raw material of said composition behind the mixing machine thorough mixing, through 1-3 hour postcooling of 600 ℃ process furnace sintering through being ground to fineness smaller or equal to 300 orders.
The feed composition of steel part high temperature label inorganic paint according to the invention need pass through with the water hybrid modulation after, the slurry that becomes mean particle size to reach below the 10 μ m through ball mill grinding promptly obtains steel part high temperature label inorganic paint.
Do not fade after steel part high temperature label inorganic paint according to the invention sprays under the condition of high temperature number, waterproof is sun-proof, and is nonpoisonous and tasteless, the sign prolonged preservation, and its result of use is suitable with the imported materials and items quality, and good and cheap, practices thrift foreign exchange.Because it is neutral that the pH value of coating of the present invention is tending towards, coating is simple to the requirement of spraying equipment and container, is difficult for stopping up spray gun and coating transport pipe because of chemical corrosion.Also because the pH value of coating of the present invention is tending towards neutral, so coating broken away from the restriction as pigment of the white titanium pigment used always greatly, can select other white pigment instead of titanium white powder in a large number for use, and this greatly reduces the cost of coating.
