Abstract

The invention discloses an organic composite dye. The organic composite dye comprises the following components in parts by mass: 60-80 parts of alkylaryl sulfonate, 40-60 parts of triethylene glycol, 30-50 parts of stearic acids, 40-50 parts of amino-o-cresol, 20-40 parts of tea polyphenol, 10-20 parts of an emulsifier and 120-160 parts of water. Meanwhile, the invention further discloses a preparation method of the organic composite dye. Compared with the traditional technology, the organic composite dye comprises a plurality of organic raw material components, the generated dye has various properties, and requirements of diversification can be met.

Description

technical field [0001] The invention belongs to the field of synthetic leather, and in particular relates to an organic composite dye and a preparation method thereof. Background technique [0002] Organic Dyes A class of dyes made from organic compounds. Dye properties include light fastness, water immersion resistance, acid resistance, alkali resistance, organic solvent resistance, heat resistance, stable crystal form, dispersibility and hiding power, etc. Organic dyes usually have high tinting strength, the particles are easy to grind and disperse, not easy to precipitate, and the colors are brighter, but their light resistance, heat resistance and weather resistance are poor. Organic pigments are widely used in the coloring of materials such as inks, paints, rubber products, plastic products, stationery and building materials. The traditional single-performance dyes can no longer meet the needs of most enterprises at present, and the performance is too single, and they...
