Described a kind of preparation method with the alcohol-base foundry coating of wearability, is characterized in that comprising the following steps:
(1) shell is put into retort calcination processing 3-4 hour at 405-520 ℃, taken out, the hydrochloric acid solution of putting into 10-12% soaks 3-6 hour, filter and take out, use clear water cyclic washing, dry and pulverize, spray vaporific white glue with vinyl and stir and evenly mix, the modification oyster shell whiting of system;
(2) together with the ethanol of modification oyster shell whiting above-mentioned steps being made and kaolin, 1/4 weight, grind and be heated to 140-160 ℃, add zinc dithiophosphate, triphenyl phosphite to keep temperature to stir 1-2 hour, be cooled to 50-60 ℃ and add magnesium chloride to grind 30-40 minute, the dry xeraphium that makes of spraying;
(3) lithium bentonite is put into calcining furnace and calcined 2-4 hour at 530-680 ℃, take out cooling, add the ethanol of 1/5 weight to stir, standing 10-12 hour, then adds sodium carboxymethylcellulose, phenolic resins, hexa to be heated to 70-80 ℃ and stirs 30-40 minute;
(4) zircon is dropped in reactor, the ethanol agitation grinding 10-15 minute that adds yellow starch gum and surplus, add again step (2), (3) product, auxiliary agent, temperature of reaction kettle is slowly risen to 75-85 ℃ simultaneously, keep temperature to stir 20-40 minute, grind until fineness reaches 50 μ m below.
