Biological coating and loss-controlling agent for fertiliser and method for preparing same

Abstract

The invention relates to a fertilizer biological capsule loss control agent and a preparation method thereof. The present capsule takes nitrocellulose as main material and tung oil as auxiliary material. The nitrocellulose is easily absorbed by human body and is easy to be inflammable and explode, and easily causes fires, so the health and safety of people are endangered. The waste gases and waste liquids generated by the nitrocellulose also pollute the environment, which have the shortcomings of going against storage, transportation and discriminating at the latter period. The capsule of the fertilizer biological capsule control agent comprises 75 to 100 percent of tung oil and 0 to 25 percent of coloring quick drying agents. The fertilizer biological capsule loss control agent has the advantages of being pure natural and renewable, being colored according to fertilizer, convenient use, greatly changing the primary effective components of fertilizer, improving soils, environmental protection, improving the utilization ratio of fertilizing efficiency, saving energy, lowering agricultural production cost, wide adaptation range and ensuring no loss of the fertilizer efficiency.

Description

technical field

[0001] The invention relates to the field of chemical fertilizers, in particular to a chemical fertilizer biological coating loss control agent and a preparation method thereof. Background technique

[0002] For a long time, the utilization rate of my country's chemical fertilizer farmland is only about 25%---35%, which not only increases the agricultural investment, but also wastes the increasingly tense chemical fertilizer raw materials. Demand, new fertilizers that reduce nutrient loss, such as the "coated slow-release fertilizer and its preparation method" disclosed in Chinese patent 02137895.9, the coating uses nitrocellulose as the main material, and the amount of tung oil added is 0-20% of the weight of the coating , Nitrocellulose is easily inhaled into the human body during the operation process, and it can spontaneously ignite when exposed to air. It is easy to burn and explode when exposed to fire or high heat. Contact with oxidants and most organi...
