| titleOfInvention | Preparation method of lignin-chitosan based fluoride-free high-strength super-hydrophobic paper |
| abstract | The present invention discloses a preparation method of lignin-chitosan based fluoride-free high-strength super-hydrophobic paper, and relates to the technical field of papermaking and polymeric functional materials; dissolving alkali lignin in a polar solvent, slowly adding an initiator to an obtained alkali lignin solution, heating to 90-180°C under protection of nitrogen, slowly adding long-chain alkane methoxysilane to react to obtain a modified alkali lignin solution, settling and purifying the modified alkali lignin solution to separate out an alkali lignin modifier, drying for later use, dissolving the alkali lignin modifier in the polar solvent again to obtain an alkali lignin modifier solution, soaking a paper pulp in the solution, stirring and adding chitosan, and performing papermaking to obtain super-hydrophobic paper; the super-hydrophobic paper has strong hydrophobicity, reutilization property and seal-cleaning capacity, is simple in operation, adopts raw materials which are cheap and rich in source, belongs to cyclic comprehensive application of biomass raw materials, and thus has good application prospect and economical benefit in the fields of waterproof protection of transport package, fresh food cold storage and high-end products. |
