preparation example Construction
[0038] The preparation method of red liquid disperse dye of the present invention comprises the following steps:
[0039] The component A, additives and water are mixed in proportion with a sand mill or grinder to make a red liquid disperse dye;
[0040] Or add half of the water, component A and additives in proportion to mix them with a sand mill or grinder, and then make up water in proportion to make red liquid disperse dyes.
Embodiment 1
[0046] Component A shown in 23 grams of formula (1), 5 grams of diffusion agent CNF, 1 gram of Pingpinga O and 1 gram of Turkish red oil are added to 70 grams of water, and ground and dispersed with a sand mill to make a red liquid disperse dye .
Embodiment 2-9
[0056] According to the composition formula in Table 1, red liquid disperse dye is made.
[0057] Table 1:
[0058]
[0059] The performance test of the red liquid disperse dyes in Examples 2-9 was carried out using the same test method as in Example 1, and the specific data are shown in Table 2.
[0060] Table 2:
[0061] name
[0062] As can be seen from Table 2, compared with Comparative Example 1-2, the red liquid disperse dyes of Examples 1-9 have a longer precipitation time, which brings great convenience for transportation and use. And the red liquid disperse dye of embodiment 1-9 is compared with comparative example 1-2 and red powdery dye, dyed foot water chromaticity is light, COD is low, more environmental protection.
