| titleOfInvention | Hydrophobic silica gel composite resin-based VOC adsorbent |
| abstract | The invention discloses a hydrophobic silica gel composite resin-based VOC adsorbent. A synthetic method for the adsorbent comprises the following steps: (1) pretreatment of silica gel; (2) silanization of the surface of the silica gel; (3) preparation of a polymer precursor of a resin and the silica gel: a step of dissolving a divinylbenzen monomer and the initiator azobisisobutyronitrile in tetrahydrofuran in an ice water bath, carrying out mixing under stirring so as to obtain a resin polymer fluid, and adding a certain amount of the resin polymer fluid in the silane-modified silica gel drop by drop to form moist silica gel; and (4) preparation of the hydrophobic silica gel composite resin-based VOC adsorbent: a step of conveying the moist silica gel prepared in step (3) to a crystallization kettle, carrying out crystallization at a temperature of 100 to 150 DEG C for 10 to 50 h so as to obtain a sample and drying the sample at a temperature of 50 to 110 DEG C for 5 to 10 h so as to obtain the adsorbent. With the synthetic method in the invention, the surface of the silica gel presents hydrophobicity, the size of a silica gel channel can be reduced, a specific surface area of the silica gel is increased, and preferential adsorption capability of the silica gel in absorption of VOC gas is greatly improved, so the hydrophobic silica gel composite resin-based VOC adsorbent has wide application prospects. |
