| titleOfInvention | A kind of polymer powder surface treatment method |
| abstract | The present invention relates to a kind of surface treatment of polymer powder, using polymer powder as raw material, comprising the following steps: Step 1: adding water-soluble polymer, aqueous medium, defoaming agent and optional amino cyclodextrin derivative Heat and mix evenly to obtain a treatment solution, the water-soluble polymer has a number-average molecular weight of 20,000 g/mol to 150,000 g/mol; step 2: Mix the polymer powder and the treatment solution, and mix them evenly to obtain a powder-containing solid liquid mixture; step 3: the mixture obtained in step 2 is subjected to solid-liquid separation and drying to obtain the treated thermoplastic polymer powder. The powder roughness is reduced through the adsorption of the water-soluble polymer to the high surface energy region of the powder, no high temperature and high pressure treatment is required, and the method is simple and safe. The processed powder can be used in powder coatings, 3D printing, cosmetics, additives, medicine and other fields. |
