Natural degradable compound fertilizer anticaking agent and preparation method thereof

Abstract

The invention relates to a natural degradable compound fertilizer anticaking agent and a preparation method thereof. The natural degradable compound fertilizer anticaking agent is prepared from the following ingredients in percentage by weight: 80 to 90 percent of rice hulls and 10 to 20 percent of additives, wherein the additives are C4 to C30 stearic acid, C4 to C30 stearate and C4 to C30 alcohol or paraffin. The preparation method comprises the following steps: feeding ingredients into a milling machine to be pulverized to 500 to 2500 meshes; and then, feeding the pulverized ingredients into a modification machine for modification processing for 3 to 10 minutes at the temperature between 10 DEG C and 150 DEG C to obtain the natural degradable compound fertilizer anticaking agent. The invention provides the natural degradable compound fertilizer anticaking agent with the advantages of simple processing, low use cost, good caking resistance performance, pure natural environment protection, convenient absorption by crops, fertilizer effect enhancement, soil protection and field return promotion of organic substances.

Description

technical field

[0001] The invention relates to a natural degradable compound fertilizer anti-caking agent and a manufacturing method thereof. Background technique

[0002] In the prior art, the anti-caking agents for compound fertilizers are generally chemical synthetic agents, which have the following disadvantages: 1. It is easy to cause pollution to the soil where the fertilizer is applied and its surrounding environment. Second, the cost is high. 3. After acting on the fertilizer, it is not easy to degrade or be absorbed by crops.

[0003] Rice husk is a by-product of rice processing, and its annual output is huge in my country, but its actual use efficiency is very low. Contents of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies in the existing technology, and provide a kind of simple processing, low use cost, good anti-caking performance, pure natural environmental protection, easy to absorb by crops, enh...
