Problems solved by technology

Molasses, a by-product of the sugar industry, is a highly dispersible substance, but it has high viscosity and strong hygroscopicity. If it is modified, it will reduce its hygroscopicity and enhance its fluidity and retain its high dispersibility. , it is expected to develop a new anti-caking agent

Abstract

The invention belongs to the technical field of agricultural chemical fertilizer, and particularly relates to an anti-blocking agent suitable for powder water-soluble fertilizer and a preparation method of the anti-blocking agent. The anti-blocking agent suitable for the powder water-soluble fertilizer comprises, in parts by weight, 500-600 parts of molasses, 200-400 parts of a viscosity reducingagent, 3-10 parts of a separant, 1-5 parts of a defoaming agent and 36-135 parts of water. The problem that molasses can not be directly used as an anti-blocking agent is solved through viscosity reduction and moisture-absorption preventing modification treatment on the molasses with high viscosity and high moisture-absorption. The excellent dispersibility of the molasses is utilized to increase the contact degree with the powder water-soluble fertilizer, universal applicability is achieved, and the anti-blocking performance of the fertilizer can be obviously improved through addition of the anti-blocking agent at an amount of 0.5-2.0% of the weight of the fertilizer; and the raw materials have wide sources, the production process is simple, the production cost is low, and large-scale production and application can be realized easily.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to an anti-caking agent suitable for powder water-soluble fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an important means of agricultural production, and the anti-caking performance of solid fertilizer is one of the important reasons affecting the circulation and application of fertilizer. With the development of my country's agricultural science and technology in recent years, fertilizer products have become more and more abundant, and new fertilizers such as water-soluble fertilizers have developed rapidly. Solid powder water-soluble fertilizers have become one of the main dosage forms of water-soluble fertilizers due to their advantages in production, packaging and transportation. Fertilizers are mostly blended with high-purity raw materials. Due to the use of small doses of sealed packaging, produc...
