Abstract
The invention belongs to a chemical additive, and relates to an anti-caking additive with slow release effect. The anti-caking additive with slow release effect is mainly characterized in that organicmodifiers with a certain weight percentages such as hydrocarbon compounds, grease and the like are evenly mixed with powdered materials such as calcium silicate and fly ash at a certain temperature by a wet method, and subject to dehydration, drying and crushed into a powder product, and the product is evenly added to various granulated chemical fertilizers for use, the product prevents chemicalfertilizers from caking after adding the product to the fertilizers in package and storage. The anti-caking additive has slow release effect after fertilization, and enhances fertilizer efficiency. The anti-caking additives has advantages of no toxic and side effect, no pollution, low cost, less usage and better anti-caking performance compared with other like products and has certain slow releaseeffect on the fertilizers. The anti-caking additive is also applicable to anti-caking for other grain products.
Description
Technical field
The invention belongs to chemical additive, be specifically related to a kind of anti-hard caking agent with slow release effect.
Background technology
China is a large agricultural country, and various fertilizer amounts and output are very big.The caking but chemical fertilizer makes moist in storage process easily causes and uses inconvenient and waste, even security incident can take place.Also there is the particulate product situation of easily luming in other granulation industry.
Existing preventing blocking technology mainly contains: 1. in the fertilizer granulation production process, directly add tensio-active agent in raw material, make absorption formation water-resisting layer on the chemical fertilizer granule, prevent adhesion between the particle; 2. after granulation, spray liquid organic compound (as paraffin), make it to wrap up in and spread on particle surface, form water-resisting layer, prevent adhesion between the particle; 3. mix with grease, paraffin, tensio-active agent and water-retaining agent, pulverize, grind and make anti-hard caking agent with atlapulgite, diatomite, talcum powder, behind fertilizer granulation, add, on chemical fertilizer granule, form water-resisting layer, prevent fertilizer caking.These methods have been alleviated the trend of fertilizer caking to a certain extent, but exist the cost height, complex process, the unfavorable problem of preventing blocking effect.
Summary of the invention
The contriver is in the investigative action to chemical fertilizers production, storage, service condition; find that existing chemical fertilizer preventing blocking technology exists certain defective; through exploring and improving; purpose is to provide a kind of anti-caking agent for fertilizer with slow release effect; after mixing in the adding chemical fertilizer; can on chemical fertilizer granule, form layer protective layer, prevent adhesion between the chemical fertilizer granule preferably, and play certain slow release effect.
The technical solution used in the present invention is a kind of anti-hard caking agent with slow release effect of preparation, adopt following weight percent raw material to process: organic modifiers 0.1%-20%, powdery material 80%-99.9%, through the mixing that stirs of wet method at a certain temperature, make organic modifiers fully be adsorbed in powdery material surface, through dehydration, drying is pulverized and is obtained product then.
Wherein organic modifiers adopts hydrocarbon compound, grease, silane coupling agent, titanate coupling agent, aluminate coupling agent, zirconium aluminate coupling agent, organic sulfonic acid and salt, organic carboxyl acid and salt thereof, organo-sulfate and salt thereof, organic amine material, quaternary ammonium salt, polyvinyl alcohol, polyoxyethylene glycol, polyacrylic ester and multipolymer thereof etc.Corresponding solvent can be water, ethanol or gasoline etc.
Wherein the powdery material adopts Calucium Silicate powder, lime carbonate, silicon oxide, titanium dioxide, calcium phosphate, monocalcium phosphate, ground phosphate rock, magnesium oxide, diatomite, flyash etc.
Above material can use separately, also can arbitrary combination use.Can also add other a small amount of organism to reach better preventing blocking effect.
This anti-hard caking agent of the present invention with slow release effect; be added in all kinds of chemical fertilizer, can strong adsorption on chemical fertilizer granule, form protective layer, the powdery material that is adopted; both as the separant of chemical fertilizer granule; as carrier absorption organic modifiers, change the surface properties of powdery material again, make it have waterproof, lubricated, anti-caking effect; more help absorption and isolation to chemical fertilizer granule; reduce simultaneously the dissolution rate of chemical fertilizer again, played certain slow releasing function, improved the fertilizer efficiency of chemical fertilizer.Compare with existing similar anti-caking agent for fertilizer, have and have no side effect, pollution-free, cost is low, and addition is few, and is easy to use, and agglomeration preventing performance is good, and chemical fertilizer is had certain advantages such as slow release effect.The anti-caking that also is suitable for other particulate product is used.
