[0034] 2. The preparation method of fertilizer dyeing agent

[0035] This method can have two kinds. First weigh the coloring agent, the toner, or the auxiliary agent according to the composition and proportion of the above-mentioned fertilizer dyeing agent, and then adopt the method comprising the following steps:

[0036] method 1:

[0037] Pulverization: Put the coloring agent (colored humic acid and its salts) into the ball mill. After the machine is turned on, adjust its speed to 500-1500 rpm. The coloring agent is crushed and released to obtain 500-800 mesh powder coloring agent , centralized collection;

[0038] Dissolution aid: Add a certain amount of dispersant and solubilizer into water heated to about 40°C, and stir evenly;

[0039] Toning: Slowly add powder colorant to the uniformly stirred auxiliary solution; then add natural brown, yellow, brown, red or black pigment toner, and stir while adding to obtain a uniformly mixed toning solution;

[0040] Grinding: ...

Embodiment 1

[0046] Embodiment 1 (using "Method 1"):

[0047] (1) Food color additives for preparing humic acid and its salts, dispersants, solubilizers, and natural coffee color pigments;

[0048] (2) Put 300g of humic acid and its salts into the ball mill. After the machine is turned on, adjust its speed to 500-1500 rpm. Humic acid and its salts are crushed and extracted to obtain 500 to 800 mesh humus Collect the powder of acid and its salts in a centralized manner; add 10 grams of dispersant and solubilizer to 1000 grams of water heated to about 40°C, stir evenly, and then slowly add 300 grams of humic acid and its salts Powder colorant; add 40 grams of natural brown food color toner to it, and stir while adding to make it evenly mixed; put this mixed solution into a ball mill and grind until humic acid and its salts are completely dissolved; The fertilizer colorant is obtained.

[0049] (3) Carry out conventional fertilizer dyeing: Dye DAP with a fertilizer dyeing agent in an amount...

Embodiment 2

[0050] Embodiment 2 (using "method 2"):

[0051](1) Prepare humic acid and its salts, dispersant, solubilizer, natural coffee color, and food color additives of yellow pigment;

[0052] (2) Add 10g of dispersant and solubilizer to 1000g of water, stir evenly, then slowly add 300g of humic acid and its salt coloring agent, and then add 30g of natural coffee color and 10g of yellow pigment to the food color The coloring agent is added while stirring to make it evenly mixed; the mixed solution is put into a ball mill for grinding until the humic acid and its salts are completely dissolved; the fertilizer coloring agent is obtained.

[0053] (3) Carry out conventional fertilizer dyeing: Dye DAP with a fertilizer dyeing agent in an amount of 0.20kg / T to 3.5kg / T, and DAP in brown color can be dyed.

Abstract

The invention relates to a fertilizer stain, which comprises colorant and toner, wherein the colorant is colored humic acids or colored humic acids salt substance, while the toner is colored foodstuff color additive and lignin as well as one sort or the mixture of a plurality of sorts of the salts; according to part by weight, 5 to 50 parts by weight account of the colorant, while 0 to 20 parts by weight of the toner. The method of preparation of the invention is as follows: firstly, the colorant and the toner are weighed according to proportion, or 0 to 20 parts by weight of dispersing agent and 0 to 20 parts by weight of solubilizer are weighed additionally; and then, method 1 including crushing, dissolution, toning and grinding or method 2 including dissolution, toning and grinding is adopted during production to obtain the natural fertilizer stain. The invention has the advantages of strong dyeing capacity, improving soil condition, reducing pesticide residue, protecting ecology environment, low cost, low dosage and non-pollution, etc.

Description

technical field [0001] The invention relates to the fields of fertilizers and dyes, in particular to the application of humic acid and its salts to fertilizer dyes and a preparation method thereof. Background technique [0002] At present, some enterprises add some dyeing agents in the process of fertilizer production to improve the color of fertilizers, and some dyeing agents are mainly composed of synthetic dyes or pigments and solvents. This dyeing agent is not easy to degrade and has certain toxicity. After entering the soil It will pollute the environment, and some carcinogenic and genotoxic substances in the dye will damage the health of humans and poultry after being absorbed by plants. Therefore, it is necessary to develop and use natural organic dyes, because natural organic dyes can not only be effectively applied to fertilizer dyeing, but also can directly become organic nutrients for crops, have good compatibility with the ecological environment, are biodegradabl...
