Method for processing pigment carbon black into color master batch applied to chemical fibers

Abstract

The invention relates to the field of pigment carbon black processing, and discloses a method for processing pigment carbon black into a chemical fiber color master batch, and the production method comprises the following steps: 1, preparing raw materials; 2, preparing materials; 3, transforming a high-speed mixing cylinder; 4, performing pigment carbon black treatment; 5, feeding by a double-screw extruder; and 6, carrying out shearing optimization. According to the method for processing the pigment carbon black into the color master batch applied to the chemical fiber, carbon black with a middle structure, an auxiliary agent with good wettability to polar and non-polar materials and resin with high fluidity and the content of 40-50 are selected; a blade structure of the high-speed powder mixing cylinder and a powder mixing process are transformed; the raw materials in the formula can be fully combined and preliminarily dispersed; a feeding section and a shearing section of the double-screw extruder are optimized; and the effects that the blackness of spun yarns is obviously improved and the spinnability is stable after the yarns are used by customers can be achieved.

Description

technical field [0001] The invention relates to the field of pigment carbon black processing, in particular to a method for processing pigment carbon black into color masterbatches for chemical fibers. Background technique [0002] At present, the solution in the industry is mainly to use low-cost "carbon black for rubber", add various additives (stearic acid, oil), and use "internal mixer" to optimize the dispersion of carbon black. Or increase the content of chemical fiber grade carbon black in the color masterbatch. [0003] However, the existing method of processing pigment carbon black into chemical fiber color masterbatches still has certain disadvantages in use, but the color masterbatch produced by the former has low cost but unstable spinnability; As the content of carbon black in the masterbatch increases (more than 30%), the spinnability of the masterbatch shows an obvious linear decline, and the "blackness" of the spun silk is still low. Therefore, we propose a ...

[0003] However, the existing method of processing pigment carbon black into chemical fiber color masterbatch still has certain disadvantages in use, but the color masterbatch produced by the former has low cost, but the spinnability is very unstable; As the content of carbon black in the masterbatch increases (more than 30%), the spinnability of the masterbatch shows an obvious linear decline, and the "blackness" of the spun silk is still low. Therefore, we propose a kind of pigment Carbon black is processed into a method for applying chemical fiber color masterbatch
