Problems solved by technology

[0003] So far, the water-based color paste products used by fertilizer enterprises to control the color in the granulation process can flow at room temperature and can be directly pumped, added evenly and measured accurately. However, when entering winter, due to the extremely high ambient temperature in the north Low, the temperature is below 0°C, the day and night temperature is lower, and often reaches below -10°C, causing the water-based color paste to freeze and solidify below zero, unable to flow and affect the addition and use; in addition, when the water-based color paste freezes and solidifies , even if it is heated by steam and a greenhouse to melt it, but due to the poor temperature resistance of the dispersant and anti-settling agent, affected by the low temperature, the original performance cannot be restored after reheating, making it difficult to add to the water-based color paste. In the water-based color paste system, there are adverse phenomena such as thickening, clustering, poor dispersion and solubility, and the coloring power of the product is also significantly reduced, which directly affects the coloring effect, dosage and production cost of the water-based color paste. At the same time, if we When heating by steam and greenhouse, under the condition of sub-zero temperature, the heating energy consumption is high, the cost increases sharply, and the heating takes a long time, which affects the addition, use and production progress of the product. Therefore, under the current demand of the fertilizer market, the development It is a very important research and development direction to produce a kind of antifreeze type and low temperature resistant water-based color paste

Abstract

The invention discloses a low-temperature-resistant water-based color paste for controlling the color of a chemical fertilizer and application, and the low-temperature-resistant water-based color paste is characterized by being prepared by mixing the following components in percentage by mass: 50.5-86.5% of water, 2-5% of a dispersing agent, 0.5-1.5% of an anti-settling agent, 10-40% of pigment and 1-3% of an anti-freezing agent. When the low-temperature-resistant water-based color paste is used for controlling the color of the fertilizer, the addition amount of the low-temperature-resistant water-based color paste is 0.01-1.50 kg / ton of fertilizer, and the addition amount of the low-temperature-resistant water-based color paste is added into slurry for producing the fertilizer. The water-based color paste is stored and used in a low-temperature environment, does not freeze and agglomerate, is uniformly dispersed, has better flowability, is convenient to meter, add and use, and can be better used for controlling the color and uniformly adding in the fertilizer production process, so that the stable color and luster of the fertilizer are ensured, the phenomenon of flower materials is avoided, and the uniform and unified appearance of the fertilizer is ensured; the method is simple in application operation, convenient to add and high in practicability.

Description

technical field [0001] The invention relates to the technical field of fertilizer color control, in particular to an antifreeze-type low-temperature resistant water-based color paste for controlling the color of chemical fertilizers and its application. Background technique [0002] At present, with the gradual depletion of phosphate rock, the grade of phosphoric acid is getting lower and lower, and the impurity content increases accordingly. The color of phosphoric acid fluctuates greatly, which directly interferes with the color of the fertilizer produced. In case of color difference, most enterprises add water-based color paste in the fertilizer production process to improve the color of the fertilizer and control the appearance of the fertilizer uniformly; at the same time, they can also choose water-based color paste of different colors according to different types of fertilizers, as fertilizer identification and Anti-counterfeiting marks, therefore, the use of water-ba...
