Problems solved by technology

[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 Pollution to the environment, some carcinogenic and genotoxic substances in the dye will damage the health of humans and poultry after being absorbed by plants

Abstract

The invention relates to a green fertilizer coloring agent and a preparation method thereof. The green fertilizer coloring agent comprises the following components in part by weight: 5 to 8 parts of coloring agent, 0 to 3 parts of toner, 0 to 10 parts of dispersant and 0 to 10 parts of compatibilizer, wherein the coloring agent is food-grade lemon yellow 1-(4-sulfophenyl)-4-(4-sulfophenyl azo)-5-pyrazolone-3-carboxylic trisodium salt and / or food-grade brilliant blue di[-N-nethyl-N-3(sulfonic benzyl) aminophenyl]-2 sulfonic methylphenyl disodium salt, and the toner is food-grade rose bengal; the green fertilizer coloring agent is prepared by adding the substances into the water according to proportion, and grinding and uniformly mixing the mixture; and the using amount of the green fertilizer coloring agent in each ton of fertilizer is 0.20 to 3.5 kilograms, and the green fertilizer coloring agent is used for coloring the fertilizer to obtain corresponding green fertilizer. The green fertilizer coloring agent has the advantages of strong coloring capability, ecological environment protection, low cost, low using amount, pollution free and the like.

Description

technical field [0001] The invention relates to the field of fertilizer dyes, in particular to the application of food-grade pigments to fertilizer green dyes and a preparation method thereof. Background technique [0002] At present, some enterprises add some dyes to improve the color of fertilizers in the process of producing fertilizers, while some dyes are mainly composed of synthetic dyes or pigments and solvents, which are not easy to degrade and have certain toxicity. Pollution to the environment, some carcinogenic and genotoxic substances in dyes will damage the health of humans and poultry after being absorbed by plants. Therefore, it is necessary to develop and use food-grade organic pigments, because food-grade organic pigments can not only be effectively applied to fertilizer dyeing, but also have good compatibility with the ecological environment, are biodegradable, and are non-polluting and non-toxic to the environment. [0003] my country is a big country in ...
