Embodiment 1
[0021] An anti-oxidation mold is made from the following raw materials in parts by weight: 20% attapulgite clay, 40% quartz sand, 30% coal gangue, 5% binder and 5% antioxidant.
[0022] The adhesive is one or a mixture of polystyrene, polyacrylate, and ethylene-vinyl acetate copolymer.
[0023] The antioxidant is one or a mixture of asphalt, rosin and sulfur boiled.
[0024] A kind of manufacture method of anti-oxidation mould, the raw material of above-mentioned weight part is obtained through the following steps:
[0025] 1) Pulverizing and sieving: After pulverizing the attapulgite clay, quartz sand and coal gangue through a pulverizer, the mixed material is obtained after sieving to remove impurities;
[0026] 2) Heating and frying: heat and fry the above-mentioned mixture through a frying machine, set the heating temperature at 230-280°C, and bake for 2-3 hours to obtain clinker for later use;
[0027] 3) Cooling: cooling the above-mentioned clinker at an ultra-low temp...
