description The invention provides a preparation method of colored modified nylon particles, which relates to the technical field of material processing. The method comprises the following steps of S1, mixing nylon and a coloring agent, carrying out melt dispersion, and carrying out extrusion granulation to obtain monochromatic particles, S2, melting the monochromatic particles, metering by a melt pump, and extruding, S3, melting, mixing and modifying the modified nylon, and extruding into strips, and S4, coating the melt extruded in the step S2 on the surface of the strip in the step S3, cooling, and dicing to obtain the colored modified nylon particles. According to the method, the pigment degradation amount can be reduced, the coloring efficiency is high, and falling is not likely to happen after coloring. 本发明提供一种着色改性尼龙粒子的制备方法,涉及材料加工技术领域。本发明的方法包括以下步骤:S1、将尼龙与着色剂混合,熔融分散,挤出造粒,得到单色粒子;S2、将单色粒子熔融,经熔体泵计量,挤出;S3、将改性尼龙熔融混合改性,并挤出成带条;S4、将步骤S2中挤出的熔体涂覆在步骤S3的带条表面,冷却,切粒,即得着色改性尼龙粒子。本发明的方法可以降低颜料降解量,着色效率高,着色后不易脱落。
