A kind of take quartz sand as the preparation method of the Hydrophobic filter material of carrier

The invention discloses a kind of take quartz sand as Hydrophobic filter material of carrier and preparation method thereof, to solve perishable, life cycle is short, backwash effect is poor problem that current fiber filtering exists.This Hydrophobic filter material take quartz sand as the Hydrophobic filter material of carrier, is made up of quartz sand and the titanate coupling agent DN101 that is attached to its surface.Its preparation methods steps is: quartz sand is after screening, immersion, cleaning, drying, react with the titanate coupling agent DN101 through alcoholysis, make the hydrophobic grouping of titanate coupling agent graft on quartz sand surface, then cleaning, drying, is prepared into Hydrophobic filter material.Hydrophilic graphite sand is modified by the present invention becomes Hydrophobic filter material, and product has the effect that intensity is high, hydrophobicity is strong.
