Abstract
The invention provides a kind of binding agent of powder pressing forming inoculant block, adopt the inoculant block of this binding agent compacting both attractive in appearance, solid, use and convenient, can effectively eliminate the inoculation fade phenomenon, this binding agent is made up of styrene-butadiene rubber(SBR), industrial paraffin and industrial naptha.
Wherein styrene-butadiene rubber(SBR) and paraffin is all as binding agent, but but the also effect of super fatting agent of paraffin.Thereby the inoculant block visual appearance that compacting is come out is good, and the intensity height is applicable to smallclothes in graphitic cast iron and the spheroidal graphite cast iron.
Description
The present invention relates to be used in the Foundry Production the employed a kind of binding agent of press-forming inoculating block, be applicable to pressing machine compression moulding inoculant block.The in-mold inoculation inoculant block that compacting is come out had both met the powder pressing characteristic, can satisfy the inoculation process of Foundry Production medium casting again well.Be applicable to the production of smallclothes in graphitic cast iron and the spheroidal graphite cast iron.
In Foundry Production, graphitic cast iron and spheroidal graphite cast iron will carry out inoculation.This is improve foundry goods tissue and performance a kind of most economical, effective means.At present, mainly be to adopt common ferrosilicon in iron notch or bag, to breed in the production.But this technology exists such problem, it is maximum that the pregnant effect of common ferrosilicon nucleating agent reaches after adding molten iron immediately, just decay even disappearance subsequently, decline rate can be very fast, so just makes foundry goods easily produce spoken parts in traditional operas and reduce its mechanical property and processing characteristics.Adopt inoculant block mould cavity inoculation treatment process can effectively eliminate the inoculation fade phenomenon, improve the mechanical property of foundry goods.Inoculant block mixes back compression moulding by powdery nucleating agent and binding agent.In molten steel pouring course, the homogeneity that nucleating agent distributes on whole foundry goods depends on the characteristic of binding agent to a great extent.At present, the binding agent kind that in-mold inoculation inoculant block was suitable for is few." strengthen inoculation and produce as-cast ferrite ductile iron " literary composition in " magnesium iron " 1985.3 and introduce, mainly contain paraffin and water glass.It is low to do the inoculant block intensity that binding agent makes with paraffin, fuses too soon, even cannot stand the thermal shocking of molten iron and " disintegration " in casting process, and it is inhomogeneous that foundry goods is bred.And staging life, is short, and gas forming amount is big.And use water glass, the inoculant block of making easily to cause slag inclusion, and easy sticking to mould, be unfavorable for producing in enormous quantities.
The objective of the invention is to provide a kind of and can satisfy pressing machine compression moulding characteristic, be suitable for producing in enormous quantities, can control the binding agent of the fusing speed of inoculant block in molten iron again.The inoculant block that feasible compacting is come out successively fuses under the encirclement of molten iron uniformly.Thereby make foundry goods breed evenly.
The present invention is raw materials used to be: styrene-butadiene rubber(SBR), 120# industrial naptha and industrial paraffin.It is as follows to fill a prescription:
Gasoline rubber solution (concentration 10～12%) 50%
120# industrial naptha 30%
Industrial paraffin 20%
Compound method is: all becoming the fritter of 10 * 10 * 10mm and 120# industrial naptha to be made into concentration in styrene-butadiene rubber(SBR) is 10～12% gasoline rubber solution, treat styrene-butadiene rubber(SBR) dissolving back sieve filtration fully in gasoline, remove micelle and be mingled with, and the precipitation certain hour, will be fused into liquid paraffin and 120# industrial naptha then and make this binding agent by last surface compositions.
Compound method of the present invention is simple, easy to use, the inoculant block intensity height that suppresses, and density is big, and appearance is bright and clean, attractive in appearance.But owing to contain gasoline, so inflammable.
Claims (2)
1, a kind of binding agent that contains paraffin that is used to suppress inoculant block is characterized in that also containing styrene-butadiene rubber(SBR) and industrial naptha.
2, binding agent as claimed in claim 1, it contains the gasoline rubber solution 50% of concentration 10～12%; 120# industrial naptha 30%; Industrial paraffin 20%.
