| titleOfInvention | Preparation method of color master batch for high-color-fastness low-melting-point polyamide |
| abstract | The invention discloses a preparation method of a color master batch for high-color fastness low-melting-point polyamide, which comprises the following steps of adding 60-95 parts by weight of a carrier, 4-40 parts by weight of a colorant and 0.1-7 parts by weight of a dispersant into a mixer, uniformly mixing, carrying out melt blending by using a double-screw extruder at the temperature of 200-230 ℃, and then carrying out granulation to prepare the color master batch for high-color fastness low-melting-point polyamide; wherein the carrier is made of a low melting point copolyamide and an ethylene-vinyl acetate copolymer; the low melting copolyamide is made from the following components: 30-40 parts of caprolactam, 10-20 parts of nylon 66 salt and 50-60 parts of diacid and diamine; wherein the molar ratio of diacid to diamine is 1: 0.9 to 1.1. The color master batch prepared by the invention has good dispersibility, strong colorability and good color fastness. |
