Abstract
The anti-caking agent for ammonium nitrate consists of diffusant, penetrant, reinforcing agent and water repellent, and features that the diffusant with anionic surface activity is used as crystal form controlling agent of ammonium nitrate, and penetrant, reinforcing agent and moisture-proof water repellent are added to control crystal form.
Description
The present invention is a kind of anti-caking agent for ammonium nitrate, relates to easily the lump moistureproof anti-hard caking agent of meal of solid, mainly as the anti-caking and the anti-setting agent of agricultural ammonium nitrate, can be used as the dust sorbent material of the powder type explosive course of processing and the dispersion agent of explosive again.This anti-hard caking agent is made up of toughener and hydrophober etc.
As everyone knows, ammonium nitrate is the most widely used agrochemical, also occupies an leading position in powder type explosive and ammonium nitrate-fuel oil mixture component.But because the easy water absorbability of ammonium nitrate, morphotrophy, salt bridge recrystallization and the easy concreteness of particulate under the loading extruding, make ammonium nitrate in storage period, easily lump, harden, not only cause shatter value to reduce to degenerate with physicals such as granule strength reduction, and give produce, storing brings major obstacles and unsafe factor.
Since half a century, people have carried out unremitting research to the easy caking defective of improving ammonium nitrate.The fifties, be devoted in ammonium nitrate, to add hydrophobizing agents such as paraffin, but the wax class exists yield value low little with the thermoplasticity scope, makes product grain intensity too low; The sixties, the Soviet Union, Japan and Britain magnesium nitrate on probation or nickelous nitrate are made dewatering agent, because easily moisture absorption of these inorganic additives itself makes the deliquescence point of ammonium nitrate reduce after the interpolation, cause product particle can not bear great volume change face in storage period and break.
The seventies, Japanese Patent 7650898 (1978) was pointed out: adopt the polar group material that contains multistage amine can make the anti-caking additive of ammonium nitrate.Acetate solubleness in ammonium nitrate too little (0.001%) of used octadecane amine produce and use inconvenience, and single alkyl amine acetate can not solve the humidity resistance of ammonium nitrate.Organic dye such as the U.S. Cook eighties (Cook M.A.) C.I. 42685 on probation are made the crystal control agent of ammonium nitrate, find in the test: C.I. 42685 just has anti-caking effect in-18~30 ℃ of scopes, in fact the ammonium nitrate product packaging temp is often above 40 ℃, this class anti-hard caking agent just lost efficacy, the goods shatter value is just defective, so use limitation too big.
In recent years, development attempts to adopt ground phosphate rock (calcium superphosphate) as the ammonium nitrate anti-caking additive, addition is 1.5%~2.6%, though make the ammonium nitrate that fertilizer efficiency is better, cost is low, but evidence: the goods physicals still degenerates rapidly with ambient moisture, temperature, and its storage period is very short; And the adhesive property of this anti-hard caking agent is poor, and the goods powder is increased, and granule strength is very low, so be difficult to practical application.Therefore the easy anti-caking of ammonium nitrate becomes people and wants for a long time to solve and unsolved technical barrier.
The objective of the invention is to overcome disadvantages of background technology, design a kind of ammonium nitrate that makes and in storage period, keep good shatter value and granule strength, be difficult for moisture absorption caking, inexpensive practicality again, the good moistureproof anti-hard caking agent of net effect.
Design of the present invention: a kind of constituent element performance complement of design preparation, with low cost, the polynary anti-hard caking agent system that can solve the ammonium nitrate inherent defect, be intended to make ammonium nitrate and anti-hard caking agent to form the anti-caking of the protection against the tide ammonium nitrate granule molecular model of an even mixed crystal crystalline structure; For this reason, must cladding there be one deck moisture-proof film on its mixed crystal crystalline surface, and the nucleus that increases granule strength must be contained in its crystalline structure center, and the diffusant of crystals and permeate agent must be able to be controlled the polymorphic transition change feature of ammonium nitrate.Therefore this anti-hard caking agent system must be made up of the permeate agent of toughener, hydrophober, the diffusant that plays the crystalline form control action kou and an auxiliary crystalline form control action kou.Wherein the design of diffusant and permeate agent is the most key, and they mainly act on is the irreversible change or the slow variation of near the control ammonium nitrate crystalline form ammonium nitrate transformation temperature, keeps obtaining free-running property satisfactory stability crystalline form; Toughener makes and forms the insoluble impurities nucleus in the mixed crystal crystal after the ammonium nitrate granulation, improves granule strength; Hydrophober mainly plays moisture-proof role, can stop the intrusion of ambient moisture, and can improve the outward appearance Forming Quality and the fragility of goods.
According to above-mentioned design, the quaternary anti-hard caking agent system of a constituent element performance complement of design; Toughener adopts the inertia breeze that contains the insoluble silicon-dioxide of high-melting-point, and this class material is: silicate, talcum powder, diatomite, montmorillonite, wilkinite, vermiculite, kaolin, pearlife, sepiolite or the molten silica gel of gas etc.; Hydrophober adopts the easy film forming material of low melting point, and this class material is: longer chain fatty acid and salt thereof, wax, polyester and mineral wet goods; Designed the compound crystal control agent that plays a crucial role, be made up of the permeate agent of a diffusant that plays main body crystalline form control action kou and an auxiliary crystalline form control action kou, diffusant or permeate agent must adopt and contain polar group-SO
