Problems solved by technology

The solvent method requires the pigment to be ground in a carrier resin and an organic solvent. Although the solvent can be recycled after use, the consumption is still quite large. Moreover, the process of producing PTT masterbatch by the solvent method is long and needs to be solved. pollution issues, etc.

Abstract

The invention discloses a PTT color master batch and preparation method therefor. The PTT color master batch comprises the following ingredients, by weight, 50%-80% of PTT resins, 20%-50% of soluble dye, 3%-5% of dispersants and 0.1%-1% of anti-oxidants. The soluble dye is a high-grade oil soluble dye. The high-grade oil soluble dye is an anthraquinone dye or a heterocycle dye after chemical purification, and comprises one selected from a yellow GG dye, a red G dye, a red EG dye, a red BB dye, a blue 2RA dye, a purple BA dye, a green G dye and a brown R dye. The beneficial effects are that the PTT color master batch has characteristics of high concentration, bright color, strong coloring power, good stability, convenient usage, low cost and the like, the coloring technologies of PTT are reduced, and environment pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PTT color masterbatch and a preparation method thereof. Background technique [0002] Polytrimethylene terephthalate (PTT) is an aromatic polyester synthesized by esterification and polycondensation (and solid-state polycondensation) of terephthalic acid (PTA) and 1,3-propanediol (PDO). Since industrialized production in the 1990s, it has been widely used in various fields of people's daily activities. PTT can be made into fibers, films, engineering plastics, etc. In particular, because PTT fiber not only has the chemical resistance and stain resistance of PET fiber, but also has the softness of nylon and the bulkiness of acrylic fiber, its elastic recovery and recovery rate are not only excellent, but its inherent bending performance and color The fastness is also very good. It is one of the newly developed popular polymer materials in the world. It is widely used ...
