Colored oily fertilizer anti-caking agent prepared from inorganic pigment and application of colored oily fertilizer anti-caking agent

Abstract

The invention relates to a colored oily fertilizer anti-caking agent prepared from inorganic pigment and application of the colored oily fertilizer anti-caking agent. The colored oily fertilizer anti-caking agent comprises the following ingredients in percentage by mass: 2-4% of iron oxide red, iron oxide yellow, iron oxide blue, iron oxide green, iron oxide purple, iron oxide brown or iron oxide black and 98-96% of an oily anti-caking agent, and is prepared by uniformly milling and mixing such ingredients by adopting a horizontal mill. The colored oily fertilizer anti-caking agent is applied to fertilizer coating, and 1.0-1.6 kilograms are used in each ton of a fertilizer, so that a corresponding color of red, yellow, blue, green, purple, brown or black is shown in the appearance of the fertilizer. The colored oily fertilizer anti-caking agent with the corresponding color of red, yellow, blue, green, purple, brown or black is provided for fertilizers with different appearance colors, so that inside and outside colors of the fertilizer are consistent, color difference and materials with inconsistent colors are avoided; the colored oily fertilizer anti-caking agent is stable and uniform in color, strong in coating capability, resistant to light and heat, colorfast and non-discoloring, can also be used as a fertilizer variety distinguishing and anti-counterfeiting mark, and is low in use cost and good in anti-caking performance.

Description

technical field [0001] The invention relates to the technical field of fertilizer anti-caking agents, in particular to the preparation of colored fertilizer anti-caking agents with inorganic pigments and its application. Background technique [0002] With the expansion and demand of the domestic fertilizer market, the problem of fertilizer agglomeration has been troubled, which directly affects the appearance quality. Agglomeration not only brings troubles to the storage and transportation of fertilizer production enterprises, but more importantly, it causes great inconvenience to users. At the same time, the vast majority of fertilizer companies currently produce different types of fertilizers according to market demand. In order to facilitate the distinction, some pigments are added during the fertilizer production process to make different types of fertilizers into different colors for identification, such as red, yellow, and blue. Green, purple, brown, black and other d...

Agglomeration not only brings troubles to the storage and transportation of fertilizer production enterprises, but more importantly, it causes great inconvenience to users

At the same time, the vast majority of fertilizer companies currently produce different types of fertilizers according to market demand. In order to facilitate the distinction, some pigments are added during the fertilizer production process to make different types of fertilizers into different colors for identification, such as red, yellow, and blue. Green, purple, brown, black and other different colors, if a layer of colorless oily anti-caking agent is coated on the surface of the fertilizer, the color of the fertilizer surface will be weakened, resulting in color difference between the inside and outside of the fertilizer, whitening of the surface, and the color will fade. Therefore, it is imperative to develop colored oily anticaking agents of different colors, and it is also a key development topic at present.
