| titleOfInvention | A high-flux anti-pollution reverse osmosis composite membrane and its preparation method |
| abstract | The invention discloses a high-flux anti-pollution reverse osmosis composite membrane and a preparation method thereof, comprising a reverse osmosis base membrane, a hydrophilic skeleton layer and an anti-pollution coating arranged in sequence; the preparation method is as follows: (1) the hydrophilic skeleton The aqueous phase dispersion of the material is poured on the surface of the reverse osmosis basement membrane, so that the aqueous phase dispersion is evenly immersed in the surface of the membrane, and after the immersion treatment, a hydrophilic skeleton layer is obtained on the surface of the reverse osmosis basement membrane; (2) Coating anti-pollution coating: put The anti-pollution modification solution is poured on the surface of the hydrophilic skeleton layer on the reverse osmosis base membrane, and after standing for 3-5 minutes for adsorption, the excess solution is removed, and the high-flux anti-pollution reverse osmosis composite membrane is obtained after heat treatment. The present invention constructs a hydrophilic skeleton layer with a two-dimensional or three-dimensional pore structure between the anti-pollution coating and the reverse osmosis base membrane to form a water molecule transmission channel, thereby reducing the loss of membrane permeation flux while ensuring the anti-pollution performance of the membrane. loss. |
