Description
Technical Field
The invention relates to a new textile material, in particular to a color master batch for antibacterial and antistatic graphene polyester spinning and a preparation method thereof.
Background
The polyester fiber is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dihydric alcohol and dibasic acid or ester, is called PET fiber for short, and is the first large chemical fiber variety with the largest volume production at home and abroad of the current synthetic fiber. With the development of new functions, the application field is expanding.
The graphene serving as a novel two-dimensional nano carbon material has excellent characteristics of high electric conductivity, high heat conductivity, high specific surface area, excellent mechanical property and the like; as an ultra-light material, the surface density of graphene is only 0.77mg/m2. Many textile field technicians are studying how to compound graphene into textile fibers such as polyester fibers and develop textile materials with new properties and new applications. Researches show that the polyester can be endowed with good antibacterial and antistatic effects by adding the graphene into the polyester. However, due to the ultra-light characteristic of graphene, a general mixing process is difficult to realizeSo as to make the material compatible with other materials.
The current graphene and polyester fiber composite method mainly comprises three methods: firstly, directly adding graphene powder into slices according to a proportion for melt spinning; due to the fact that the graphene powder is large in specific surface area and ultra-light in weight, the process can be achieved, but graphene is difficult to disperse in fibers uniformly. And secondly, directly soaking or padding the fiber in a graphene solution, and then drying to obtain the fiber carrier with the surface coated with the graphene, wherein the graphene can only be attached to the surface of the fiber by a soaking method, the attachment fastness is low, and the attached graphene is often in an agglomerated state. Thirdly, polyester and functional mother particles containing graphene are mixed and spun. Among the three methods, the third method is that the graphene is combined in the fiber more firmly, the graphene is less agglomerated, and the production environment is more sanitary and safer.
The conventional graphene polyester master batch is prepared by simply mixing various component powder materials and then granulating, for example, the polyester master batch disclosed in the Chinese patent application with the application number of CN109183181A is obtained by mixing and granulating dried graphene powder and the like with the polyester powder materials, but the two-dimensional property and the nanometer property of graphene enable the graphene to be easily agglomerated in the polyester master batch, the two-dimensional property is difficult to fully exert, and the subsequent fiber spinning is easy to break. Another method is that as disclosed in chinese patent application CN109762305A, a fiber material is padded, dried, coated for many times in graphene slurry, and then granulated; the fiber has a multilayer sandwich structure before granulation, and through multiple padding, wrapping and granulation, although the dispersibility of graphene in master batches and the fiber is improved, the heterogeneous sandwich structure is inevitably introduced into the master batches and subsequent fibers, and from the production of the master batches to the final finished product of polyester fiber, the polyester material is subjected to wire drawing at high temperature for at least three times, and the polyester performance has the inevitable deterioration. The patent application of CN108084686A also discloses a conductive masterbatch containing graphene, which is prepared by mixing graphene with polyester after ultrasonic treatment in an inert volatile organic solvent to form a dispersion, and then melt-extruding, but there are problems of environmental pollution such as solvent volatilization. In addition, there is a method of adding graphene dispersion liquid in the polyester polycondensation process, such as the patent application disclosed in CN108503804A, in contrast, this process is complicated, the concentration, addition rate and polyester polycondensation rate of graphene dispersion liquid need to be strictly controlled, if the synthesis is not properly controlled, graphene is easy to agglomerate, and the performance of the polycondensation product is difficult to be stably ensured.

s1, preparing graphene dye color paste:
s1-1, weighing and proportioning: weighing a formula, wherein the formula comprises the following components in percentage by weight: 0.5-15% of S-type high-temperature disperse dye, 0.3-4% of graphene oxide powder, 5-10% of dispersing agent, 0.1-2% of thickening agent, 0.05-2% of defoaming agent and the balance of water;

s1-3, nano grinding; injecting the uniformly dispersed and stirred mixture into a ceramic nano grinder by using a liquid pump for vacuum grinding, and stopping grinding when the particle size reaches within 300nm to obtain graphene dye color paste;
s2, mixing; adding the graphene dye color paste and the unbleached polyester chips into a high-speed mixing mill according to the weight ratio of 1: 4-10, heating, mixing, modifying and coloring at the mixing temperature of 170-230 ℃ to form a colored polyester mixture;
s3, smelting and co-extrusion: melting and co-extruding the colored polyester mixture in a double-screw extruder at the melting temperature of 190-;
s4, granulation: and smelting and co-extruding the colored polyester melt by a screw machine, bracing, water cooling, granulating, drying and packaging to obtain the antibacterial antistatic graphene polyester spinning color master batch.

Preferably, the thickener is an acrylate polymer. The acrylate polymer thickener has the advantages that through the same-polarity electrostatic repulsion of carboxylate ions, molecular chains are spirally extended to be rod-shaped, a net structure is formed among disperse dye particles, and the viscosity of a water phase is improved, so that the thickening effect is achieved. The key point is that the slurry is subjected to a lasting shearing action in the stirring dispersion and nano grinding processes, the thickening effect of the thickening agent is not influenced by shearing, and the dye and graphene gradually dispersed and ground are protected by the thickening agent and cannot settle, so that the thickening effect is better, and the stability of the color paste is higher.
The defoaming agent mainly plays a role in inhibiting bubbles generated in the friction process of shearing dispersion of materials. Preferably, the defoaming agent is a nonionic multiphase silicone polymer. The nonionic defoaming agent is adopted, has strong defoaming capability and strong alkali resistance, and particularly still plays a good defoaming role in the presence of alkaline sodium lignosulfonate.
In order to improve the dispersion effect, the preferable technical scheme is that in the step S1-2, the S-type high-temperature disperse dye is pre-dispersed in water, and the pre-dispersed S-type high-temperature disperse dye and other ingredients are mixed in a shearing dispersion mixer; the pre-dispersion is to soak the high-temperature disperse dye in water, stir and dissolve the dye, and obtain the dye dispersion after filtering the dye by a 300-mesh filter screen. The dispersion uniformity of the graphene dye color paste is improved through pre-dispersion.
In order to keep the stable performance of the graphene dye color paste, the preferable technical scheme is that in the step S1-2, the pre-dispersed water temperature is lower than 45 ℃. Similarly, the preferable technical solution further includes that in the step S1-3, the temperature of the grinding process is controlled within 50 ℃.
In order to improve the dispersion effect, the preferred technical scheme is that the step S1-3 comprises two steps of coarse grinding and fine grinding. Through coarse and fine grinding, the grinding efficiency is improved, the dye and the graphene can reach superfine nano-grade dispersion in the graphene dye color paste, the tinting strength of the color master batch for the antibacterial and antistatic graphene polyester spinning is greatly improved, and the color master batch can smoothly enter the interior of a polyester material in subsequent processing and achieve dispersion and combination in a molecular degree. Further preferably, the coarse grinding uses grinding beads with the particle size of 0.4mm and a filter screen with the pore size of 0.5 mm; the fine grinding uses grinding beads with the grain diameter of 0.2mm and a filter screen with the aperture of 0.3 mm.
The invention also provides an antibacterial and antistatic graphene polyester spinning color master batch, which is prepared by the preparation method of the antibacterial and antistatic graphene polyester spinning color master batch.
