| titleOfInvention | Modified starch and preparation method therefor and application thereof |
| abstract | The present invention relates to a modified starch and a preparation method therefor and an application thereof. The modified starch is mainly prepared from starch and a cationic starch complexing agent; The chemical structure of the cationic starch complexing agent consists of the following components: i) one or more hydrophobic groups, wherein at least one hydrophobic group is capable of reacting with starch to form an inclusion complex, and ii) one or more hydrophilic groups, wherein at least one hydrophilic group is a cationic hydrophilic group. The hydrophobic group and the hydrophilic group are respectively at both ends of the same molecular structure and are connected by means of a chemical bond to form an asymmetric and polar structure. The use of the modified starch in papermaking can greatly increase the adsorption rate of starch on the surface of the fiber or in the pulp, thereby increasing the retention rate of the starch in the paper, improving the strength of the paper and reducing or even eliminating the loss of starch in the pulping and papermaking process and further reducing COD emissions. |
