Abstract

The invention discloses an azo compound dye. The azo compound dye comprises the following components in parts by mass: 80 to 100 parts of azodiisobutyronitrile, 30 to 40 parts of m-phenylenediamine, 40 to 60 parts of sodium lauryl sulphate, 20 to 30 parts of monostearin, 10 to 30 parts of p-methyl aniline, 10 to 30 parts of a curing agent and 120 to 150 parts of water. Meanwhile, the invention further discloses a preparation method for the azo compound dye. Compared with the prior art, the stability of the azo compound dye is improved by adding organic aromatic groups with high stability and performing low temperature modification treatment, and the influence on the decomposition of a plurality of carcinogenic aromatic hydrocarbons caused by the environment is avoided.

Description

A kind of azo composite dye and preparation method thereof

Technical field

The invention belongs to Dyestuff synthesis field, be specifically related to a kind of azo composite dye and preparation method thereof.

Background technology

It is fabric clothing most widely used class synthetic dyestuffs in dyeing and printing process that the azo group two ends of azo dye connect a class organic compound of aryl, for the multiple natural and dyeing of synthetic fibers and stamp, is also used for the coloring of paint, plastics, rubber etc..Traditional azo dye character is unstable, can decomposite multiple carcinogenic aromatic hydrocarbons under certain conditions, all have no small injury in environment in human body.

Summary of the invention

Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of azo composite dye.

Another object of the present invention is to provide the preparation method of above-mentioned azo composite dye.

Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically achieved in that a kind of azo composite dye, component including following mass fraction: the azodiisobutyronitrile of 80 ~ 100 parts, the m-diaminobenzene. of 30 ~ 40 parts, the sodium lauryl sulfate of 40 ~ 60 parts, 20 ~ 30 parts of monoglycerides, the open-chain crown ether of 10 ~ 30 parts, the firming agent of 10 ~ 30 parts and the water of 120 ~ 150 parts.

Wherein, described firming agent is mixed by cumyl peroxide, di-isopropylbenzene hydroperoxide and Diethylenetriamine 3:3:1 in mass ratio, is heated to 35 degrees Celsius with ultrasonic machine ultrasonic 10 ~ 15 minutes.

The method preparing azo composite dye, comprises the following steps:

(1) by azodiisobutyronitrile, m-diaminobenzene., sodium lauryl sulfate, monoglyceride, open-chain crown ether, firming agent imports in reactor and is heated to 80 degrees Celsius, stirring mixing 30 ~ 40 minutes；

(2) in reactor, continuously add water, do not stop stirring, continue 10 ~ 20 minutes；

(3) step (2) gained mixed liquor is passed through the psychrolusia of less than 5 degrees Celsius；

(4) step (3) gained mixed liquor is filtered, collect crystallization, packaging warehouse-in after standing 1 ~ 2 day.

Beneficial effect: the present invention, compared with conventional art, processes by adding the high organic aromatic hydrocarbon group of stability and low temperature modification the stability of azo composite dye is got a promotion, it is to avoid the later stage decomposes multiple carcinogenic aromatic hydrocarbons because of environmental effect.
