Nanometer carbon nanotube doped wet blasting sand material for pump body casting processing

The invention discloses a nanometer carbon nanotube doped wet blasting sand material for pump body casting processing, and relates to the technical field of wet blasting processing. The nanometer carbon nanotube doped wet blasting sand material is prepared from, by weight, 90-100 parts of quartz sand, 15-20 parts of bentonite, 5-8 parts of nanometer carbon nanotube powder, 12-15 parts of river sand, 8-11 parts of alumdum, 6-9 parts of feldspar powder, 5-8 parts of putty powder, 3-5 parts of cement, 1-2 parts of tallow amine, 0.5-1 part of zinc carbonate, 25-30 parts of ethanol and 280-300 parts of water. Bentonite is modified by the carbon nanotube, so improvement of comprehensive performances of the sand material is benefited; and the prepared sand material can be directly used in wet blasting treatment of a pump body casting, so the roughness of the casting surface is reduced, scales, rusts, oil stains and other impurities on the surface are removed, and subsequent coating spraying and pump assembling are benefited.
