Preparation method of fertilizer colorant and application method thereof

Abstract

The invention relates to a preparation method of a fertilizer colorant and an application method thereof. The preparation method comprises the following steps of: respectively dissolving water-soluble dyes such as bright red, rose red, acid blue, brilliant blue, golden yellow or lemon yellow into water; respectively adding 1-3% dispersing agent; stirring and respectively preparing into red inner colorant, blue inner colorant and yellow inner colorant for later use; respectively dissolving oil-soluble dyes such as lithol red, toluidine red, phthalocyanine blue, transparent blue, benzidine yellow or fluorescence yellow into base oil dissolvent; respectively adding the 1-3% dispersing agent; stirring and respectively preparing into red outer colorant, blue outer colorant and yellow outer colorant; directly stirring and blending the inner colorants and fertilizer raw materials; and spraying the outer colorants, so that the fertilizer is evenly colored. The preparation method can prepare the colored fertilizer which can not discolor under the functions of strong acid, strong base, strong reductant, strong oxygenant and microbe, and has the characteristics of small use amount of the colorant, stable coloration, low cost, pure color, good appearance, wide adaptability, high safety, good performance and the like.

Description

technical field

[0001] The invention relates to a method for preparing and using a coloring agent, in particular to a method for preparing and using a fertilizer coloring agent, and belongs to the technical field of fertilizer dyeing. Background technique

[0002] With the development of chemical technology, dyeing technology has gradually entered the field of fertilizer production technology. Some fertilizer manufacturers add some dyes or coloring agents in the process of fertilizer production. On the one hand, it is to prevent others from counterfeiting their own brands. On the one hand, it is to improve the appearance and color of fertilizers, and at the same time, it is convenient for users to intuitively identify the varieties and brands of fertilizers. The dyes or colorants used for fertilizer dyeing are divided into water-soluble and oil-soluble types. The general dyes are composed of dyes or pigments and solvents. Some solvents or dyes are not easy to degrade and wil...

Examples

Embodiment 1

[0015] The water-soluble dye scarlet is dissolved in water, and then 1% of modified sodium lignosulfonate dispersant is added, and after stirring, red inner coloring agents are prepared respectively.

[0016] Dissolve the oil-soluble pigment Lisol Scarlet in the base oil solvent, add 1% modified sodium lignosulfonate dispersant, stir and make red external colorants respectively.

[0017] Use 0.1‰ internal colorant to directly stir and mix with fertilizer raw materials, and then spray the chemical fertilizer raw materials that have been stirred with internal colorant with external colorant to make the fertilizer evenly colored.

Embodiment 2

[0019] Dissolve the water-soluble dye scarlet in water, add 3% modified sodium lignosulfonate dispersant, and stir to make red internal colorants respectively.

[0020] Dissolve oil-soluble pigment Lisol Scarlet in base oil solvent, then add 3% modified sodium lignosulfonate dispersant, stir and make red external colorants respectively.

[0021] Use 0.3‰ internal colorant to directly stir and mix with fertilizer raw materials, and then spray the chemical fertilizer raw materials that have been stirred with internal colorant with external colorant to make the fertilizer evenly dyed in color.

Embodiment 3

[0023] Dissolve the water-soluble dye scarlet in water, add 2% modified sodium lignosulfonate dispersant, and stir to make red internal colorants respectively.

[0024] Dissolve oil-soluble pigment Lisol Scarlet in base oil solvent, then add 2% modified sodium lignosulfonate dispersant, stir and make red external colorants respectively.

[0025] Use 0.2‰ internal colorant to directly stir and mix with fertilizer raw materials, and then spray the chemical fertilizer raw materials that have been stirred with internal colorant with external colorant to make the fertilizer evenly dyed in color.
