The chemical fertilizer provided by the invention can make active ingredients be released slowly and gradually, has a good embedding effect on volatile and freely soluble chemical nitrogen fertilizers, can be gradually released in the growing process of crops, and has the function of acting for a long time. The utilization ratio of the chemical fertilizer is increased.
Description
Technical field
The invention belongs to the chemical fertilizer field, especially a kind of new type chemical fertilizer and preparation method thereof.
Background technology
Chemical fertilizer, as easy moisture absorption caking such as ammonium nitrate (hereinafter to be referred as the state), 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.
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 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, additive one anti-hard caking agent that has just had chemical fertilizer industry to use.
At present, generally need add additive in chemical fertilizer regulates the concentration of chemical fertilizer and alleviates the problem of easy moisture absorption caking but present additive is the additive of chemosynthesis, 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, after chemical fertilizer is executed on the soil, the soil is become to harden, the market conditions variation is unfavorable for the farming that circulates.
According to the retrieval, find following patent documentation about fertilizer additive, wherein CN102030584A discloses a kind of fertilizer additive, and it is made of according to the following number of weight ratio following component: poor: shell: stalk: ammonium carbonate fertilizer containing=12-27: 20-45: 43-62: 55-82.The present invention is a raw material with vinasse, contains a large amount of yeast and acetic bacteria in the vinasse, decomposes the back and produces the material that helps crop growth in a large number, helps the growth of farm crop; Have sterilization and anti-microbial effect behind the shell high-temperature calcination; With the stalk is that raw material can increase and upgrade the soil organism, promotes microbial reproduction, improves the physico-chemical property and the biological activity of soil.CN1733659 discloses a kind of method of utilizing stellerite to prepare fertilizer additive, it is characterized in that the steps include: that (1) is raw material with the natural parastilbite ore deposit, and raw ore is eluriated, and grinding and processing is to the 60-120 order; (2) with 10 gram stellerites, 100 moles of 1MNH4Cl solution, with 10 gram stellerites, 1MNaCl solution 100 molar ratios, preparation ammonium type and sodium type stellerite were placed 8 hours under the room temperature, and washing is to there not being chlorion.CN1219526 multipurpose high-effective chemical fertilizer additive, it is characterized in that: this additive is powdery or waxy solid, it mainly comprises aniorfic surfactant, rare earth element, synergistic agent and water, aniorfic surfactant is alkylsulfonate or benzene sulfonate, one of naphthalenesulfonate and one of alkyl carboxylate or alkylamine carboxylate salt, the ratio of the two is 1: 1～8: 1, wherein the carbon number of sulfonate alkyl is 1～12, the carbon number of carboxylate salt alkyl is 10～20, rare earth element is a lanthanum, the nitrate of cerium or in the vitriol one or both, any proportioning, synergistic agent is a kaolin, ground dolomite, in the sepiolite powder one or more, any proportioning, by gross weight 100, each composition weight ratio scope of the present invention is: powdery agent wax shape agent 60～89.9, aniorfic surfactant 50～84.9, rare earth element 0.1～5, synergistic agent 10～35, water 5～15.CN1078713 discloses a kind of additive for composite chemical fertilizer, and its weight percent consists of: active zeolite 40-85%, and activation shell 10-40%, potassium primary phosphate 2.5-30%, urea 1-25%, surplus is a vitriolate of tartar.
By finding that relatively there are bigger difference in above-mentioned patent documentation and the application on raw material and preparation technology.
