Description
Technical field
It is especially a kind of special using alumina powder as the sand mo(u)ld of main material production the present invention relates to zirconia-corundum refractory brick coating
Use coating.
Background technique
In order to produce the fused cast refractories of higher quality, the sand mo(u)ld of fused cast refractories production at present has upgraded to resin sand sand mo(u)ld, sets
Rouge sand sand mo(u)ld can generate carbon dioxide gas and other gases under the condition of high temperature in casting process, these gases can make brick
Disadvantage more than face color pastiness, brick face stomata, in order to avoid these disadvantages, sand mo(u)ld inner core needs brushing high-temperature resistant coating, with painting
Layer separation gas endangers fused cast refractories surface, and the high-temperature coatings that fused cast refractories sand mo(u)ld uses are helped with zirconium matter material of main part, with other
Water based paint made of the non-auxiliary material of agent, coating cost is very big, 15000 yuan of zirconium quality high-temperature finished product coating market price per ton,
20 kilograms of mo(u)ld blacking dosage per ton, 300 yuan are converted into, this is a very big investment in fused cast refractories production process, occupies electricity
Molten brick sells a certain proportion of profit, therefore the reduction of fused cast refractories sand mo(u)ld coating cost is imperative.
Summary of the invention
For above situation, for the defect for overcoming the prior art, the purpose of the present invention is to provide one kind just with alumina powder
For the sand mo(u)ld special coating of main material production, can effectively solve the problems, such as to reduce cost using alumina powder production coating.
The technical solution that the present invention solves is：It is a kind of using alumina powder as the sand mo(u)ld special coating of main material production, packet
Include the raw material of following weight：Water 5.3-6.7kg, alumina powder 10.75-14.75kg, xanthan gum 6-10g, polyethylene 38-42g.
Preferably, the raw material including following weight：Water 6kg, alumina powder 12.75kg, xanthan gum 8g, polyethylene 40g.
A kind of preparation method of sand mo(u)ld special coating, includes the following steps：
(1) water of 4.5-5.5kg is poured into blender, and 250g alumina powder and 6-10g xanthan gum is added, and stirring is extremely
It is uniformly mixed；
(2) remaining alumina powder is added in mixture made from step (1), is stirred until homogeneous；
(3) 0.8-1.2kg water is poured into pot, and 38-42g polyethylene is added, be placed on stove fire, tanning is until poly- second
Alkene melts completely；
(4) polyethylene solution of step (3) is poured into while hot in mixture made from step (2), stir evenly to get.
Preferably, the Baume degrees of sand mo(u)ld special coating obtained is 79-82.
The formula of the invention is reasonable, greatly reduces the cost of manufacture of fused cast refractories sand mo(u)ld coating, and fused cast refractories per ton can save painting
Material expense is about 200 yuan, and 10,000 tons of fused cast refractories sand mo(u)lds can be 2,000,000 yuan of saving color expense, and alumina powder refractoriness can reach
2010-2050 DEG C or more, the high temperature resistant requirement of fused cast refractories sand mo(u)ld high-temperature resistant coating, the alumina powder market price per ton can be met
3200 yuan, coating use cost will be will be greatly reduced as fused cast refractories mo(u)ld blacking, and the use of alumina powder is sand mo(u)ld coating
Grade of fit it is higher because coating sintering after formed one layer of hard shell, not only prevent resin burn when gaseous contamination brick face, coating
The hard shell formed at high temperature can smoothly fall off naturally in brick output, and the cleaning of brick face is more convenient, improve the efficiency of brick face cleaning,
It is the innovation on fused cast refractories sand mo(u)ld coating, there is good social and economic benefit.
Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to embodiments.
Embodiment 1
The present embodiment sand mo(u)ld special coating includes the raw material of following weight：Water 5.3kg, alumina powder 10.75kg, xanthan gum
6g, polyethylene 38g.
The preparation method of the present embodiment sand mo(u)ld special coating, includes the following steps：
(1) water of 4.5kg is poured into blender, and 250g alumina powder and 6g xanthan gum is added, and stirring is equal to mixing
It is even；
(2) remaining alumina powder is added in mixture made from step (1), is stirred until homogeneous；
