Description
Technical field
The present invention relates to casting field, more particularly to a kind of lost foam casting coating field.
Background technology
Lost foam casting is described as " green casting technology " and " foundry engieering of 21 century " with its unique advantage.From
The sixties in last century has started using since in China, and through the continuous development of decades, the application of lost foam casting is continuous
Expand, obtain good economic benefit and social benefit.
Lost foam casting coating is one of two big key technologies of lost foam casting process.The performance of coating directly affects casting
The quality of part, has dramatically different with traditional sand mold cast paint.The main purpose of traditional sand casting coating is to prevent foundry goods
Penetration and chemical scab are produced, and coating for dispellable mould casting is also cast with formation and holding in addition to above-mentioned two effect
The important function of part cavity, therefore it must have higher normal temperature strength, elevated temperature strength and suitable hot permeability.
Although lost foam casting process since the advent of the world is comparatively fast developed, coating technology annoyings casting finished products always
Rate is difficult to larger raising, and its quality for being primarily due to coating can not meet the requirement of lost foam casting process.One is
Normal temperature strength does not reach requirement, causes apperance deformation and coating breakage to scrap foundry goods during moulding；Two is that elevated temperature strength is relatively low, is poured
Occur during note foundry goods die cavity subside, destroy, coating peel off etc. scrap foundry goods；Three is that coating does not have suitable hot permeability,
Too high gas permeability causes die cavity to subside, and too low gas permeability makes foundry goods produce the casting flaws such as pore, elephant skin, slag inclusion.
The content of the invention
For the deficiencies in the prior art, an object of the present invention is to provide a kind of Water-based coating for lost foam casting,
The coating elevated temperature strength and low temperature intensity and other performance all meet lost foam casting use requirement, and process is simple, cost
It is cheap.
For achieving the above object, the technical solution used in the present invention is：
A kind of Water-based coating for lost foam casting, the coating are made up of following components by weight percentage：150-200
Mesh mullite powder 15-18%, 80-150 mesh silica flour 5-8%, 200-320 mesh bauxite 12-18%, Ludox 1.2-1.5%,
Poly vinyl acetate emulsion 1.5-3.0%, carboxymethyl cellulose acid sodium 0.1-0.4%, the stupid sodium sulfonate 0.15-0.35% of alkyl, sodium sulphate
0.15-0.35%, n-octyl alcohol 0.1-0.3%, AEO 0.10-0.18%, surplus is water.
Wherein, the coating preferably constitute for：150-200 mesh mullite powder 16-17%, 80-150 mesh silica flour 6-7%,
200-320 mesh bauxite 14-16%, Ludox 1.3-1.4%, poly vinyl acetate emulsion 2.4-2.6%, carboxymethyl cellulose acid sodium
0.2-0.4%, sodium alkyl benzene sulfonate 0.20-0.30%, sodium sulphate 0.20-0.30%, n-octyl alcohol 0.1-0.3%, poly alkyl alcohol
Oxygen vinethene 0.14-0.16%, surplus is water.
Wherein, the coating optimum is consisted of：150-200 mesh mullite powder 16%, 80-150 mesh silica flour 6%, 200-
320 mesh bauxites 15%, Ludox 1.5%, poly vinyl acetate emulsion 2.5%, carboxymethyl cellulose acid sodium 0.3%, alkyl benzene sulphonate
Sodium 0.25%, sodium sulphate 0.25%, n-octyl alcohol 0.2%, AEO 0.15%, surplus is water.
The preparation method of above-mentioned coating is：
A. mullite powder, silica flour and bauxite base-material are stirred in coating grinding equipment, is subsequently adding total water
Base-material in base-material is moistened and is stirred out by the water of the 35% of amount；
B. by Ludox, poly vinyl acetate emulsion, carboxymethyl cellulose acid sodium, sodium alkyl benzene sulfonate, sodium sulphate, n-octyl alcohol, fat
Fat alcohol APEO is sequentially added in the above-mentioned base-material for having moistened and having stirred out, and add total Water 5% water in painting
30-60min is stirred in material grinding equipment.
C. and then by the water of surplus in coating grinding equipment, and grind 120-180min.
From up to 1800 DEG C of fusing point for being because mullite powder in base-material based on mullite powder, heat resistance is good,
Mullite powder low thermal expansion, makees base-material using mullite powder, and coating low temperature and elevated temperature strength are good, thermal conductivity, and does not come
Stone flour heat storage coefficient is high, is conducive to accelerating the cooling of foundry goods, refines foundry goods work layer tissue and increases the spoken parts in traditional operas of foundry goods working lining
Layer depth, is conducive to improving foundry goods service life.Be additionally added silica flour and bauxite in addition, silica flour fusing point up to 1713 DEG C, and
Quartzy powder density 2700kg/m3, bauxite fusing point be more than 1770 DEG C, add appropriate silica flour and bauxite improve painting in base-material
The suspendability of material.Water-based coating for lost foam casting adopts 150-200 mesh mullite powder 15-18%, 80-150 mesh silica flours
5-8%, 200-320 mesh bauxite 12-18%, is conducive to obtaining with good low temperature and elevated temperature strength performance as aggregate
High-quality cast product.Graphite powder, talcum powder and diatomite are not added with base-material, are conducive to environmental protection without graphite, and talcum
Contain the crystallization water in powder and diatomite, easily decompose under the effect of high-temperature metal liquation and discharge the crystallization water and form vapor immersion
Molten metal, easily forms the casting flaws such as pore in foundry goods after solidification.
Coating of the present invention with Ludox, poly vinyl acetate emulsion carboxylic and Methyl cellulose acid sodium as main binding agent, both with height
Warm bonding agent, has low temperature adhesive again.The substitution value of the carboxymethyl cellulose acid sodium selected by the present invention is 0.65-0.85, is gathered
Right n ＞ 200.Carboxymethyl cellulose acid Main Function of the sodium in coating has：One is to form netted stereochemical structure by macromolecular chain；
Two is that Polymer adsorption hydrone forms solvated layer；Three are acted on shear thinning.Carboxymethyl cellulose is added in coating
After sour sodium, thickening phenomenon is formed, makes paint adhesion effect improve.
In order to improve the suspendability of coating, the present invention adds sodium alkyl benzene sulfonate and sodium sulphate.
Easily occurs foam in coating, if removing not in time, it will affect dope layer surface quality, and then affect foundry goods matter
Amount, adds n-octyl alcohol in coating, not only acts on good froth breaking, also with the effect for improving coating wetability.
In order to improve the wettability of coating, prevent dope layer from cracking and flaking off, fatty alcohol polyoxy second is added in coating
Alkene ether makees surfactant, can significantly improve the combination property of dope layer, is highly beneficial to improving casting quality.
The present invention using water as carrier, with low cost, preserve, transport and it is easy to use the features such as.
The inventive method has the beneficial effect that：
The Water-based coating for lost foam casting of the present invention has excellent performance, with good suspension and thixotropy；
Coating also has good gas permeability and higher surface strength, meets the requirement of coating for dispellable mould casting well.Should
Coating method is simple, nonhazardous, and the surface finish of casting of production is high.This coating is mainly used in lost foam casting production casting
Iron, cast steel and non-ferrous alloy casting.Compared with same kind of products at abroad, in the case where quality is suitable, required cost reduces by 50%.
Instant invention overcomes refractory powder is expensive in existing routine casting coating preparation technology, coating material production is relatively costly to be lacked
Fall into；Cast paint of the present invention is smooth and viscosity is suitable simultaneously.
With reference to embodiment, the invention will be further described：
