Abstract
The invention discloses a cast steel lost foam coating formula. The cast steel lost foam coating formula comprises quartz powder, high aluminum powder, CMC (carboxy methylated cellulose), white emulsion, water-soluble phenolic resin, n-octyl alcohol, sodium-based bentonite, active agents, iron oxide red and graphite powder. The invention provides a water-based lost foam coating for casting, which is more favorable for gradually stripping and saves more cost after being sintered.
Description
Technical field
The present invention relates to technical field of refractory materials, specifically belong to cast steel lost foam coating formula.
Background technology
Lost foam casting, claim again cavityless casting, normally using foamed plastics (EPS, STMMA or EPMMA) macromolecular material to make becomes and the design of part that will produce casting, the duplicate full mold mould of size, through dip-coating fireproof coating and after drying, be embedded in dry quartz sand through three-dimensional vibrating moulding, casting molding flask pours into molten metal liquid under negative pressure state, the gasification of being heated of macromolecular material model is extracted out, and then replaced by liquid metals the novel casting method that the disposal molding New Casting Technique that formed after cooled and solidified is produced foundry goods.Wherein dip-coating fireproof coating mainly plays strengthening, bright and clean, permeation functions.
Summary of the invention
The object of this invention is to provide cast steel lost foam coating formula, be more conducive to and that peel off gradually, more cost-saving water group lost mould casting paint after a kind of sintering is provided.
The technical solution used in the present invention is as follows:
Cast steel lost foam coating formula, comprises silica flour, high-alumina fly, CMC cellulose, white glue with vinyl, water soluble phenol resin, n-octyl alcohol, sodium base Peng Run soil, activating agent, iron oxide red, graphite bronze.
Described silica flour 20% and high-alumina fly 80%, the percentage that CMC cellulose, white glue with vinyl, water soluble phenol resin, sodium base Peng Run soil, iron oxide red, activating agent account for silica flour and high-alumina fly total amount is CMC cellulose 1.2%, white glue with vinyl 3.5%, water soluble phenol resin 4%, sodium base Peng Run soil 4.5%, iron oxide red 0.5%, activating agent is that Tween-80 0.05% or activating agent are OP-10 0.2%, graphite bronze 5-30%.
Described silica flour 20 orders and more than.
Operating procedure:
Silica flour, high-alumina fly are pressed 100Kg proportioning, and all the other in proportion
1, cellulose is diluted with 80 ° of C hot water, cellulose: water=1:5-10, soaks and within 12 hours, is starchiness
2,, by starchiness CMC, water soluble phenol resin, the about 20Kg of water, pour mould wash mixer into and stir approximately 10 minutes
3, add that silica flour, n-octyl alcohol a small amount of (about 1-2 bottle cap), sodium base Peng Run soil, water add in right amount, activating agent, prepare stirring, after 1 hour, add white glue with vinyl, within 2-3 hour, can use.
When A, dilution cellulose, with keg, contained waterside and added limit to stir; B, first with the keg dilution that is filled with water, stir while adding sodium bentonite, then pour in mixer; C, silica flour purity are greater than 96%, bauxite purity is greater than 75%.
Compared with the prior art, beneficial effect of the present invention is as follows:
After the invention provides a kind of sintering, be more conducive to and that peel off gradually, more cost-saving water group lost mould casting paint.

Operating procedure:
Silica flour, high-alumina fly are pressed 100Kg proportioning, and all the other in proportion
1, cellulose is diluted with 80 ° of C hot water, cellulose: water=1:5-10, soaks and within 12 hours, is starchiness
2,, by starchiness CMC, water soluble phenol resin, the about 20Kg of water, pour mould wash mixer into and stir approximately 10 minutes
3, add that silica flour, n-octyl alcohol a small amount of (about 1-2 bottle cap), sodium base Peng Run soil, water add in right amount, activating agent, prepare stirring, after 1 hour, add white glue with vinyl, within 2-3 hour, can use.
When A, dilution cellulose, with keg, contained waterside and added limit to stir; B, first with the keg dilution that is filled with water, stir while adding sodium bentonite, then pour in mixer; C, silica flour purity are greater than 96%, bauxite purity is greater than 75%.
