Embodiment 1
[0021] A multifunctional surface sizing agent for paper packaging, made from the following ingredients:
[0022] Diatomaceous earth 5, nanocrystalline cellulose 4, simethicone oil and n-hexane mixture 30, chitosan 40, bletilla striata powder 10, modified chitosan 5;
[0023] In the mixture of methyl silicone oil and n-hexane, the content of simethicone is 20%.
[0024] Further, its preparation method comprises the following steps:
[0025] (1) Dip diatomaceous earth into a mixed acid solution 10 times its volume, stir at a speed of 300rpm for 1h, then take it out and put it in a microwave device, treat it at 500W for 10s, wash it with distilled water 3 times after taking it out, and then put it in Roast at 300°C for 3 hours before use;
[0026] (2) Put the nano-microcrystalline cellulose and the diatomite obtained in step (1) into a blender, mix evenly at 500 rpm, spray it with a mixture of dimethyl silicone oil and n-hexane while stirring, and wait until the surface is mois...
