AI Technical Summary

Problems solved by technology

At present, the dyeing properties of inkjet dyes are not very compatible, and the hydrophilicity and lipophilicity between them are quite different, and the directness and water solubility of fibers are quite different. Precipitation will cause stains, and the affinity for fibers is also quite different, which is easy to cause color flowers, resulting in a low rate of genuine products after dyeing.
To some extent, the application of reactive dyes is limited

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with specific embodiments.

[0019] The anti-acid rain stable inkjet dye involved in the present invention is formed by mixing three kinds of reactive dyes of dye A, dye B and dye C, and the mass percentages of the three kinds of reactive dyes of dye A, dye B and dye C are: dye A: 15- 45%; Dye B: 10-35%; Dye C: 25-60%; the rest are additives;

[0020] Dye A contains any one or more than one as shown in formula (1)

[0021]

[0022] Among them: R1, R2, R3, R4 are -H, -CH3, -OCH3, -SO3M; X is -CH2CH2OH, -CH2CH2OSO3M; M is Na, K or H;

[0023] Dye B contains any one or more than one of formula (2)

[0024]

[0025] Wherein: x+y+z=2.5-5.5; R5, R6 are -H, -SO3M; M is Na, K or H.

[0026] Dye C contains any one or more than one of formula (3)

[0027]

[0028] Wherein: R7, R8, R9, R10 are -H, -CH3, -OCH3, -SO3M; X is -CH2CH2OH, -CH2CH2OSO3M; M is Na, K or H.

[0029] As a preference, ...

Abstract

The stable spray paint dye with acid rain prevention capacity is formed by mixing three reactive dyes including dye A, dye B and dye C and is prepared from 15%-45% by mass of the dye A, 10%-35% by mass of the dye B and 25%-60% by mass of the dye C and the balance of additives. Compared with the prior art, the dye has the following beneficial effect of good outdoor acid rain prevention capacity.

Description

technical field [0001] The invention belongs to the field of inkjet dyes, in particular to an acid rain-proof and stable inkjet dye. Background technique [0002] As a representative of the modern dye industry, inkjet dyes have developed rapidly in recent years. At present, the dyeing properties of inkjet dyes are not very compatible, and the hydrophilicity and lipophilicity between them are quite different, and the directness and water solubility of fibers are quite different. Precipitation will cause stains, and the affinity to fibers is also quite different, which is easy to cause color flowers, resulting in a low rate of genuine products after dyeing. To some extent, the application of reactive dyes is limited. [0003] In addition, the inkjet dyes used for outdoor walls are still somewhat deficient in acid rain resistance. Therefore, the present invention provides an acid rain-resistant stable inkjet dye by continuously improving its functions and formulations accordi...
