Abstract

The invention discloses an azo composite dye, which comprises the following components in parts by mass: 80-100 parts of azobisisobutyronitrile, 30-40 parts of m-phenylenediamine, and 40-60 parts of dodecanol Sodium sulfate, 20~30 parts of monoglyceride, 10~30 parts of p-methylaniline, 10~30 parts of curing agent and 120~150 parts of water. At the same time, the invention also discloses a preparation method of the azo composite dye. Compared with the traditional technology, the present invention improves the stability of the azo composite dye by adding highly stable organic aromatic hydrocarbon groups and low-temperature modification treatment, and avoids the decomposition of various carcinogenic aromatic hydrocarbons due to environmental influences in the later stage.

Description

technical field [0001] The invention belongs to the field of dye synthesis, and in particular relates to an azo composite dye and a preparation method thereof. Background technique [0002] A class of organic compounds in which the azo groups of azo dyes are connected to aryl groups at both ends are the most widely used synthetic dyes in the printing and dyeing process of textiles and clothing. They are used for dyeing and printing of various natural and synthetic fibers, and are also used for paints. , plastic, rubber and other coloring. Traditional azo dyes are unstable in nature, and will decompose a variety of carcinogenic aromatic hydrocarbons under certain conditions, causing considerable harm to the environment and the human body. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a kind of azo complex dye for the deficiencies in the prior art. [0004] Another object of the present invention is to provi...
