The invention discloses a polyamide color masterbatch colored with high content of carbon black for spinning and a preparation method thereof. The polyamide color masterbatch comprises the following raw materials in parts by weight: 50-60 parts of modified polyamide, 3-5 parts of crosslinking agent 1-3 parts, 1-3 parts of modified carbon black, 1-3 parts of 2-perfluorododecyl ethyl methacrylate; the modified polyamide reacts with the cross-linking agent, so that the isocyanate on the cross-linking agent and the modified The hydroxyl group on the polyamide is reacted, and then copolymerized with modified carbon black and 2-perfluorododecyl ethyl methacrylate to obtain a polyamide color masterbatch. The molecular chain side chain of the polyamide color masterbatch contains long Chain fluorocarbons make the polyamide masterbatch have a good hydrophobic effect, and at the same time, the molecular main chain of the masterbatch contains a benzoxan structure, which greatly improves the heat resistance of the polyamide masterbatch. |
