preparation example Construction

[0042] A preparation method of a colorful fertilizer anti-caking agent with metallic luster, comprising the following steps:

[0043] S1. Weigh the raw materials according to the ratio of each component, then add the mica powder and talc powder into the purified water, stir and mix thoroughly, and raise the temperature to 70°C for 2 hours of activation to obtain a mixed solution;

[0044] S2. After the activation of the mixed solution in S1 is completed, adjust the pH value of the mixed solution to 3 with hydrochloric acid, and continue to heat up to 85° C., then stop heating to obtain solution A;

[0045] S3, adding titanium dioxide into 20% hydrochloric acid solution to fully dissolve it, and adding it to solution A in S2, stirring and mixing the solution for 4 hours at the same time, and keeping the pH value of the mixed solution constant at 3 with hydrochloric acid, and then Use sodium hydroxide solution to adjust the pH of the solution to 10, and finally obtain solution B...

Abstract

The invention provides a colorful fertilizer anti-caking agent with metallic luster and a preparation method thereof. The colorful fertilizer anti-caking agent with metallic luster is prepared from the following raw materials in parts by weight: 20%-70% of mica powder, 50%-70% of talcum powder, 1%-10% of titanium dioxide, 0.3%-1.5% of metallic oxide, 0.5%-1.5% of metallic pigment, 1%-3% of dispersing agent and 0.01%-1% of stabilizer. According to the colorful fertilizer anti-blocking agent with the metallic luster and the preparation method thereof, the mica powder, the talcum powder and the titanium dioxide are all natural ore powder with a layered structure and are mixed with the metal oxide, the metallic pigment and the like respectively, so that the layered structure of the natural ore powder can be opened, the powder with the metallic luster is formed, the excellent effect of preventing the fertilizer from caking is guaranteed, the powder also has the metallic luster effect, and compared with a traditional color effect directly presented through dye, agricultural pollution cannot be caused, and the agent is safer and more environmentally friendly to use.

Description

technical field [0001] The invention relates to the field of anti-caking agents, in particular to a colorful and metallic fertilizer anti-caking agent and a preparation method thereof. Background technique [0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. role. [0003] At present, the compound fertilizer product is a kind of inorganic salt mixture, and its moisture absorption point is affected by each raw material itself and the joint action. When more than three kinds of raw materials are mixed and reacted, the moisture absorption point is far lower than that of a single raw material, resulting in Compound fertilizer products are easy to agglomerate. At the same time, the...
