| titleOfInvention | A kind of diesel composite filter paper and preparation method thereof |
| abstract | The invention relates to the technical field of filter paper preparation, solves the problem that the strength of the filter paper is lowered due to the high moisture content of the filter paper, and discloses a diesel composite filter paper and a preparation method thereof. The filter paper includes a first carbon fiber layer, a second carbon fiber layer and a base paper sandwiched between the first carbon fiber layer and the second carbon fiber layer; the preparation method is that the base paper is first immersed in an aqueous solution of carboxymethyl chitosan, and then immersed in polyvinyl acetate The cross-linking reaction occurs under the action of ethyl silicate in the solution, and a layer of three-dimensional network cross-linked film is covered on the surface of the base paper. Finally, the intermediate of the composite filter paper is sandwiched between the activated first carbon fiber layer and the second carbon fiber layer. In between, press rolls with a double-roll hot press to obtain diesel composite filter paper. The three-dimensional cross-linked networked film covered on the surface of the base paper of the present invention has a strong hydrophobic effect, plays a protective role on the base paper, prevents the base paper from absorbing moisture and causes the strength to deteriorate, and the base paper is not easily broken under the action of oil pressure. |
