| titleOfInvention | Modified adhesive for paper cultural relics and preparation method thereof |
| abstract | The invention discloses a modified adhesive for paper cultural relics, which, in parts by weight, comprises: 90-99.5 parts of wheat starch, 0.5-10 parts of modified additives, and 450-900 parts of water, wherein the wheat starch The amylose content is 15%-30%, and the amylopectin content is 70%-85%; the modified additive is one or more compounds that can react with hydroxyl and/or carboxyl groups. The modified adhesive for paper cultural relics of the present invention has improved pH value, is moderately alkaline, moderate in viscosity, moderate in peeling degree, has a certain anti-mildew ability, and has good hand feeling in actual use, and the coated paper is resistant to tension. , tear, folding resistance and its aging strength, paper pH value, contact angle and its aging properties have better performance. |
