Fused ring aromatic pigment and polymer material mixture, preparation method and downstream product thereof

Abstract

The invention relates to a fused ring aromatic pigment and polymer material mixture, a preparation method and a downstream product thereof. According to the method, different thermoplastic polymer materials can be selected and mixed with reactants for generating fused ring aromatic pigments; by adjusting the reaction molar ratio of the raw materials and the use amounts of the raw materials in thewhole reaction system, the mixture of the reactant and the high polymer material can be extruded or kneaded to obtain the fused ring aromatic pigment and polymer material mixture in one step; and compared with the pigments, the mixture of the invention has the following characteristics that the raw material reactants of the pigment have good dispersity in the high polymer material so as to directly generate and uniformly disperse the pigment in the polymer material through extruding or kneading, the solvent is not required to be added in the extrusion or kneading process, the o-diamine compound is almost completely consumed, the obtained mixture does not need to be purified, the generation of three-waste in the traditional pigment synthesis process is avoided, the process flow is greatly simplified, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a mixture of condensed ring aromatic pigments and polymer materials, a preparation method and downstream products thereof. Background technique [0002] Fused-ring aromatic vat dyes (Vat Dyes) have bright color and excellent fastness, especially in light fastness and solvent resistance. However, due to the poor dispersion of fused-ring aromatic compounds in the production process, it is necessary to use high-boiling-point, difficult-to-remove solvents, resulting in a large amount of waste liquid, and because the purification of dye molecules is also very difficult, so that the reaction yield of such dyes is low and the price is low. High, and the processing technology is relatively more complicated, which greatly limits the application and development of this type of dye. [0003] US20080139813 uses metal catalysts such as ammonium molybdate, molybdenum oxide, molybdenum carbon...
