A kind of modified carbon black applied to spinning resin coloring and preparation method thereof

Abstract

The invention belongs to a modified carbon black colorant and its preparation, in particular to a modified carbon black used in spinning resin coloring and a preparation method thereof. Modified carbon black is shown in formula I, wherein, ● is carbon black, R is C 1 -C 30 straight-chain alkyl, branched-chain alkyl or C 1 ~C 10 of alkylbenzenes. The colorant of the present invention is suitable for the coloring of resins. The colorant is blue-light black, and the colorant particles are soft. The dispersibility of the colorant is detected by a scraper fineness meter, and the dispersibility of the colorant is more obvious than that of carbon black before modification.

Description

A kind of modified carbon black applied to spinning resin coloring and preparation method thereof technical field The invention belongs to modified carbon black colorant and preparation, be specifically related to a kind of modified carbon that is applied to spinning resin coloring Black and its preparation method. Background technique The dope dyeing method is to add appropriate colorant in the spinning solution, after fully mixing, dissolving and filtering, it can also be added in the spinning solution. Before entering the spinneret, quantitatively inject colorant or colored dope, and after mixing in a static mixer, it is spun into colored fibers. This This process is a physical change, the advantage is that the coloring and spinning can be carried out continuously at the same time, the coloring is uniform, the color fastness is good, and the dyeing rate is high. The production cycle is short, the cost is low, and the pollution is less. It can make some highly or...

Problems solved by technology

Its purpose and advantages are relatively obvious. The disadvantage is that the reaction grafting rate is low. Due to the inertness and porosity of carbon black itself, it will have a greater steric hindrance to the reactive group. When reacting with polymers, impurities Impossible to remove, the product quality is difficult to achieve the desired result

[0006] None of the above methods can be directly applied to the coloring of resin fibers, especially the dope coloring of filament fibers and fine denier filaments.
