| titleOfInvention | Preparation method of hydrophobic sand core material |
| abstract | The invention discloses a preparation method of a hydrophobic sand core material, and belongs to the technical field of hydrophobic material preparation. The method comprises the following steps of exposing a sand core material to an organosilane reagent atmosphere, and carrying out condensation polymerization on the organosilane reagent and hydroxyl on the surface of the sand core material to form a hydrophobic silane coating, wherein the method comprises the following steps: and adding an organic silanization reagent into the container, placing the organic silanization reagent and the sand core material into the container, and heating the container in a closed manner to ensure that the organic silanization reagent is gasified and fully contacts and reacts with the sand core material to obtain the hydrophobic sand core material. The method has the advantages of simple process, no environmental pollution and low cost, and the hydrophobic modified sand core funnel obtained by the method has good hydrophobicity, can be used in the fields of wastewater treatment, oil-water separation, emulsion separation and the like, and has good industrial application prospect. |
