摘要 (Abstract) |
|
A method for preparing carbon black-containing polyamide masterbatches is provided. The method includes the following steps: mixing water-soluble polyamides and carbon blacks in a solvent to obtain a carbon black dispersion; drying the carbon black dispersion to obtain a mixture; and compounding polyamides and the mixture to obtain the carbon black-containing polyamide masterbatches. The weight ratio of water-soluble polyamides to carbon blacks is about 1:1 to about 1:5. The water-soluble polyam |
