Description
technical field 3
The present invention relates to the low-cost iron casting coating using in a kind of foundry production, exfoliated red iron casting coating of especially a kind of sintering and preparation method thereof.
Background technology
In foundry production, the surface quality of foundry goods depends primarily on casting mold (core) working surface.At casting mold (core) working surface, apply coating, can not only prevent that cast(ing) surface from producing the defects such as scab, burning into sand and pit, can also reduce surface roughness, significantly reduce cast(ing) surface and level workload, obtain many-sided technique effect and good overall economic efficiency.
At present generally to take microlite ink powder and the crystalline graphite powder of black be basic refractory material to iron casting coating.Graphite powder refractoriness is high, and price is low, under pouring temperature, can separate out bright carbon, thereby forms layer protecting film at coating surface, can reduce the wettability of molten iron to casting mold, can effectively prevent the scab defect being produced by metal penetration.But the blacking of black is when preparation and use, severe contamination working environment, worsens working condition; Graphite powder also can be oxidized under high temperature liquid iron effect, and strength of coating and anti-molten iron scouring capability are reduced, and causes the anti-stick sand effect of thick large-sized iron casting bad; The blacking of black is close with the color of furan resin-sand, and inconvenience identification, easily causes holiday., although can overcome the above problems, cost is too high for albescent zircon flour coating (as patent CN86100032A " light-coloured coating for iron-casting core "), and zirconium English powder has certain radioactivity, is difficult to spread.Although tan brown corundum class coating is better to the anti-stick sand effect of thick large-sized iron casting, cost is still higher, and it is darker that painting color is still disliked.Patent CN1847336A " light-colored alcohol-base paint " for example, take brown corundum and zirconium English powder is Main Refractory, also contains 10%～25% graphite powder.
In recent years, the light color cast iron paint development and application of domestic alternative zircon flour coating has made some progress, some units have started to adopt cheap bauxite powder, silica flour, mullite powder, the light refractory material such as magnesia powder is developed the exfoliated iron casting coating of low-cost alcohol radical light color sintering for several resin sand, but these coating still exist sintering fissility still poor, anti-stick sand effect is bad, or suspension stability is poor, coating easily produces precipitation in long-term storage and transportation, coating brush mark is serious, affect the problems such as surface quality of foundry goods, and the sintering flux (or claiming Nucleating Agent) that part coatings adopts is the high ultra-fine pyroxene of price, lanthanum/strontium and rare earth class or nanometer aluminum, zirconium, the ultrafine solids dusty materials such as chromium (as patent CN101088660A " light color cast iron paint of high alumina polycrystalline composite aggregate "), most of coating still contains part graphite powder in addition, color is dark (being light gray or grey) still.
Iron casting coating divides two kinds of alcohol-base paint and water based paints.Alcohol radical iron casting coating generally adopts ethanol, methyl alcohol for example, as solvent (aforementioned patent CN1847336A and CN101088660A), has the advantages that expenditure of time is few, and after ignition, its drying process can complete.But methyl alcohol is poisonous, human body optic nerve is had to stronger excitant, workers with long time exposure easily causes eyes blind; Ethanol and methyl alcohol all belong to the dangerous material of easy volatilization and burning, and security incident easily occurs in coating material production, transportation, preservation and use procedure, are not easy to product long-distance transport and deposit; Ethanol and methyl alcohol or basic chemical raw materials and important motor vehicle fuel.In addition, after alcohol-base paint ignition, organic binder bond wherein and organic suspending agent composition produce a large amount of toxic gases, pollute working environment, affect workman healthy.Aspect coating brushability, because the polarity of alcohols is very weak, alcohol-base paint does not have time thixotropy, so brush mark is serious while brushing, and is difficult to disappear.
Table 1 has compared the characteristic of property of water based paint and alcohol-base paint.
The Performance Ratio of table 1 water based paint and alcohol-base paint
Current, energy-conserving and environment-protective and safety in production require increasingly stringent, the requirement of surface quality of continuous castings is also improved day by day.Therefore, from the viewpoint of improving operating environment, saving energy and reduce the cost, improve production security and surface quality of continuous castings etc., ethanol, methyl alcohol all should not continue to use in cast paint, and the developing direction of following iron casting coating should be take cleanliness without any pollution, safe and reliable, stable performance, convenient transportation, the cheap exfoliated water based paint of the even colored sintering of light color as main.But water based paint sintering fissility of the prior art is poor, the unpacking cooling rear coating of foundry goods is difficult to automatically peel off in flakes, and most of coating need to utilize shot-blasting machine to clear up, even if scab position adopts shot-blasting machine to be also difficult to clean out.
