Flame-retardant color master batch applicable to polyester filaments

Abstract

The invention discloses a flame-retardant color master batch applicable to polyester filaments. A preparation process for the flame-retardant color master batch comprises the following steps: A, material weighing; B, material mixing; C, extrusion; D, granulation; and E, packaging after inspection is passed. In the step A, weighed raw materials for the flame-retardant color master batch are composed of, by mass, 10-40 parts of PET, 10 to 30 parts of PBT, 20 to 60 parts of a flame retardant, 0 to 30 parts of toner and 0 to 10 parts of a dispersant, wherein the PET is bottle-grade chips or superbright chips; the PBT is an engineering plastic; the flame retardant is a pure small-molecular phosphate compound; the toner is an inorganic pigment or solvent dye of various colors; and the dispersant is polar wax. According to the invention, the flame-retardant color master batch is composed of desired parts by mass of the PET, the PBT, the flame retardant, the toner and the dispersant and are prepared through material weighing, material mixing, extrusion, granulation and the like, so the production quality of the flame-retardant color master batch can be improved, and the interests of companies are guaranteed.

Description

technical field [0001] The invention relates to the technical field of flame-retardant color masterbatches, in particular to a flame-retardant color masterbatch suitable for polyester long fibers. Background technique [0002] The color masterbatch is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant, and has good compatibility with the material to be colored Sex, that is: pigment + carrier + additive = masterbatch, masterbatch is a new type of special colorant for polymer materials, also known as pigment preparation, color masterbatch is mainly used in plastics, color masterbatch is composed of pigment or dye, carrier Composed of three basic elements and additives, it is an aggregate made by uniformly loading super-normal pigments in the resin, which can be called a pigment concentrate, so its coloring power is higher than that of the ...

AI Technical Summary

Problems solved by technology

Color masterbatch is generally composed of three parts, namely colorant, carrier and dispersant. After mixing by high-speed kneader, it is crushed, extruded and pulled into granules. Color masterbatch has high concentration and dispersibility in the process of plastic processing. Good, clean and other significant advantages, the traditional production process of colored masterbatch is usually: ABS slice grinding powder, stir into the toner, mix evenly, put into the screw extruder, pull the strip after melting, and pelletize to get the finished product. This production process Because it is necessary to grind ABS slices and then mix them with toner, not only the process is complicated, but also the production cost of masterbatch is increased. At the same time, it is difficult for people to ensure the accuracy of each process, resulting in the production quality of masterbatch. Therefore, , we propose a flame retardant masterbatch suitable for polyester filament
