Slow release coated wax of efficient slow release composite fertilizer

Abstract

The invention relates to a slow release coated wax of an efficient slow release composite fertilizer. The slow release coated wax of an efficient slow release composite fertilizer is glistened particles, and is prepared through a reaction of main raw materials comprising 42-75wt% of refined wax, 15-50wt% of microcrystalline wax, 35-55wt% of beeswax, 18-33wt% of palm wax and 1-10wt% of Chinese insect wax, and substances comprising an additive, an assistant, a biodegradation promotion substance, an acidic mixture and an organic material at 95-105DEG C for 20-40min. The slow release coated wax of an efficient slow release composite fertilizer has the advantages of simple preparation, wide raw material sources, good toughness and strength, good slow release effect in soil, neutralization of alkaline soil, and no pollution to the environment.

Description

technical field [0001] The invention relates to a slow-release coating wax of a slow-release compound fertilizer. Background technique [0002] my country is a large agricultural country. With the rapid growth of population, in order to ensure the simultaneous growth of grain production, a large amount of chemical fertilizers are used. However, due to volatilization, loss, infiltration and other reasons, the low utilization rate of chemical fertilizers is caused. This is not only economic loss and waste of resources, but also causes considerable pollution to the living environment and endangers human health. Professor Hou Yanlin of the National Academy of Sciences said that there are three main aspects of chemical fertilizer pollution. One is that after the nitrogen in chemical fertilizers enters the atmosphere, it increases "greenhouse gases" and causes the temperature to rise; the other is that the chemical fertilizers left in the soil are washed away by heavy rain When i...

AI Technical Summary

Problems solved by technology

At present, most coated slow-release fertilizers use solvents to dissolve the coated resin. Although the film material can be sprayed on the surface of fertilizer particles, the energy consumption is high, and the solvent is difficult to recover, resulting in large-scale pollution of the production workshop and the surrounding environment.

In addition, the various paraffin coatings nowadays do not have good toughness and strength. They will break when touched or bent, and it is difficult to wrap them on the surface of the fertilizer, so that the paraffin and the fertilizer are separated from each other and released. The slow-release performance is very poor. The core of the fertilizer is easy to dissolve, which greatly reduces the utilization rate of the fertilizer and cannot achieve the desired effect. It will also cause corresponding pollution to the environment
