Abstract
The present invention provides a multipurpose high-effect chemical fertilizer additive in the form of powder or ceraceous solids. The present invention mainly comprises an anion type surface active agent, rare-earth elements, a synergistic agent and water, not only can admirably prevent the moisture absorption and the agglomeration of ammonium nitrate, but also has very good agglomeration preventing effect on ammonium hydrogen carbonate, urea, etc.; the plants can be promoted to absorb the nitrogen in chemical fertilizers; autologous rare-earth elements of the present invention can promote plant growth and can also balance the nutrient in the soil, improve soil structure and prevent land hardening.
Description
The present invention is a kind of Powdered or waxy solid fertilizer additive, belongs to the fine chemistry industrial circle.
Chemical fertilizer, as easy moisture absorption caking such as ammonium nitrate (hereinafter to be referred as AN), bicarbonate of ammonia, urea, this is a undisputable fact, this is determined by the distinctive character of chemical fertilizer itself, but the chemical fertilizer of caking has brought great trouble and inconvenience to the user.Because bicarbonate of ammonia etc. only is a kind of fertilizer, do not involve the others purposes, and AN is not only a kind of fertilizer, or the oxygenant of widespread use on the industrial explosive, describes so the present invention is example with AN.
The moisture absorption caking of chemical fertilizer can be explained with " salt bridge " theory, and after the chemical fertilizer moisture absorption, the surface forms one deck saturated solution film, and under capillary effect, saturated solution is set up " liquid bridge " between the particle that closes on.When air themperature reduces or humidity when reducing, dissolved chemical fertilizer is partly or entirely crystallized out in " liquid bridge ", forms the close particulate of hard matter, and chemical fertilizer granule is bonded together securely, and Here it is so-called " salt bridge ".Because the effect of " salt bridge " makes chemical fertilizer form lump.
AN moisture absorption caking very easily in the chemical fertilizer, ordinary granular AN (salable product) places that its shatter value generally just can not reach " GB2945-89 ammonium nitrate " middle requirement after one month, the salable product shatter value is for being not less than 80%, if placed three months, its shatter value only has more than 50 percent.
AN is during as agricultural fertilizer, and it is formed bulk and is difficult for being executed spilling, and can not beat again and pulverize it, because of itself being exactly a kind of explosive, fiercely knock very easily and blast, almost all have at home every year, cause casualties, property damage because of pulverizing the explosion caused accident of AN; As industrial explosive usefulness, then must increase by one pulverizing process again, consuming time expensive.So how to solve the problem of fertilizer caking, just become the task of top priority, also therefore, the additive-anti-hard caking agent that has just had chemical fertilizer industry to use.
At present, anti-hard caking agent commonly used in the chemical fertilizer industry mostly is inorganicss such as phosphoric acid salt, calcium salt, their add-on is big (0.2～0.5%), and effect is extremely not obvious, place after three months, its shatter value does not reach the GB requirement, and usually influences the performance of the industrial explosive of producing with them that AN does.
The purpose of this invention is to provide a kind of multi-usage fertilizer additive, it not only can prevent the moisture absorption caking of AN admirably, and anti-well caking effect is also arranged for chemical fertilizer such as bicarbonate of ammonia, urea, not only can promote the absorption of plant to nitrogen in the chemical fertilizer, the rare earth element of itself can promote plant-growth, nutrient in can also balance soil, the structure of improving the soil prevents the hardening soil.
Realize that technical solution of the present invention is: a kind of multi-usage fertilizer additive, this additive is powdery or waxy solid, it comprises aniorfic surfactant, rare earth element, synergistic agent and water, aniorfic surfactant is one of sodium laurylsulfonate or sodium naphthalene sulfonate and one of aluminum stearate or octadecylamine acetate, the ratio of the two is 1: 1-8: 1, rare earth element is a kind of in cerous nitrate or the cerous sulfate, synergistic agent is a kind of in kaolin, the sepiolite powder, by gross weight 100, each composition weight ratio scope of the present invention is:
Powdery agent wax shape agent cationic surfactant 60～89.9 50～84.9 rare earth elements 0.1～5 0.1～5 synergistic agent 10～35 10～30 water 5～15
The prescription of this additive has three distinguishing features: 1. this prescription adopts composite aniorfic surfactant as main ingredient.Because the difference of their performances, carboxylate salt can prevent the chemical fertilizer moisture absorption, and Sulfonates can stop " liquid bridge " to form, and they act on alone, supplement and complement each other again, can destroy and prevent the formation of " salt bridge " well, thereby prevent fertilizer caking.Add-on is very little, but can prevent the moisture absorption caking of AN, bicarbonate of ammonia, urea, ammonium chloride etc. admirably.2. rare earth element and promoting agent mating reaction promote the absorption of plant to nitrogen in the chemical fertilizer, and can promote plant-growth.Balance nutrient, the structure of improving the soil prevents the hardening soil.3. the suitable collocation of synergistic agent and anion surfactant had both promoted its effect dynamics to " salt bridge ", made it increase the performance that prevents the soil caking simultaneously again
