Abstract
The invention discloses a kind of polynutrient anti-blocking synergy urea, contain granular urea and coating feed composition, coating is grouped into the one-tenth of feed composition by following weight part: sal epsom 60-95, polyacrylamide 2-15, Xylo-Mucine 0.5-4, Sodium dodecylbenzene sulfonate 0.5-4, water 378-1770, sodium nitrophenolate 5-15, α-Nai Yisuanna 5-15, coating is 1 with feed composition and granular urea by weight: 100-500, coating of the present invention forms a coating film with feed composition at the granular urea particle surface, thereby plays anti-caking and anti-atomizing good result; The collaborative mutually decomposition rate of nitrogen that makes of each composition needs nitrogen rule consistent with crop, can improve the utilization ratio of nitrogen in the urea, promotes plant-growth simultaneously, satisfies the demand of crop to magnesium; Therefore this product is a kind of many nutrition and the highly effective carbamide that can prevent caking, and technology is simple, and cost is low, is fit to promote.
Description
Technical field
The present invention relates to fertilizer field, relate to a kind of anti-caking urea and preparation method thereof specifically.
Background technology
The general nitrogen stress of China's agricultural land soil, applied nitrogen are one of key measures that ensures high yield, stable, high-quality, high-efficiency agriculture.At present, the principal item of the world and China's nitrogenous fertilizer is urea.Advantages such as urea is with its available nutrient concentration height, and is functional, stores and transports easily, easy to use are admitted by consumers in general.But homemade urea is used back ubiquity agglomeration problems in the process neutralization of transportation, storage, has a strong impact on product appearance and utilization ratio, and urea is lower in the utilization ratio of using back nitrogen on the other hand.
The urea from caking phenomenon is because the recrystallization process on urea granules surface is caused, at first the water migration of urea granules inside absorbs airborne moisture to particle surface or urea, form a thin water layer at particle surface, when temperature changes, the moisture that the surface absorbs will reevaporate, the saturated solution of particle surface " liquid bridge " will become " brilliant bridge ", thereby makes urea from caking.At present domestic relevant for the report that adds inorganic anti-hard caking agent, the mineral filler of adopting has diatomite, bentonite sodium, wilkinite calcium, kaolin, zeolite etc., mineral filler is adsorbed on the urea granules surface, prevent caking by buffer action, though certain effect is arranged, but consumption is big, and excessive mineral filler also can cause dust, causes environmental pollution.
Urea is lower in the utilization ratio of using back nitrogen, at present, the slow release method of nitrogenous fertilizer is all being greatly developed in countries in the world, coated carbamide is exactly wherein a kind of, its method for making is the film that is coated with one deck insoluble at urea granules surface bag, controls the release of nitrogen by membrane permeability, reaches the need nitrogen requirement that applied once satisfies the crop whole growing, and can alleviate the nitrogen loss that causes owing to decomposition, volatilization, leaching etc. greatly, improve the utilization ratio of nitrogen.At present external Envelope type urea is mainly sulfur-coated urea and polymer capsule urea, coated carbamide has the weakness of two maximums: the one, and expensive price, the 2nd, be subjected to environment-stress, its macromolecular material of selecting for use takes ability degraded in 30 years, and 1O～20% of coated fertilizer ingredients constitute coated fertilizer total amount, the ratio that consumes is higher, if life-time service, the coating residue will inevitably bring the serious environmental consequence to soil.Now only can be used for garden crops such as the higher fruit tree of park, meadow, golf course and economic worth, vegetables and flowers.Several main coated carbamide of domestic present formation has coating urea, phosphogypsum coated carbamide and fused(calcium magnesium)phosphate coated carbamide, these products all have the slow control action kou, can improve utilization rate of nitrogen fertilizer, with although to compare coating quantity abroad few, cost is lower, but its slow-releasing majority is too fast, can not match with the need nitrogen rule of farm crop, still there is big gap with states such as Europe, the United States, days on the production technology, is not used for agriculture production so far as yet not fairly largely.
Summary of the invention
Purpose of the present invention just is to provide a kind of polynutrient anti-blocking synergy urea, and this preparation method of urea also is provided.
Purpose of the present invention can realize by following measure:
A kind of polynutrient anti-blocking synergy urea contains granular urea and coating feed composition, and described coating is 1 with feed composition and granular urea by weight: 100-500.
Above-mentioned polynutrient anti-blocking synergy urea, described coating is grouped into the one-tenth of feed composition by following weight part: sal epsom 60-95, polyacrylamide 2-15, Xylo-Mucine 0.5-4, Sodium dodecylbenzene sulfonate 0.5-4, water 378-1770, sodium nitrophenolate 5-15, α-Nai Yisuanna 5-15.
The preparation method of above-mentioned polynutrient anti-blocking synergy urea, may further comprise the steps: a. takes by weighing sal epsom 60-95 part, polyacrylamide 2-15 part, Xylo-Mucine 0.5-4 part, Sodium dodecylbenzene sulfonate 0.5-4 part mixes, b. add 378-1770 part water again and make the aqueous solution, c. in the aqueous solution that step b makes, add sodium nitrophenolate 5-15 part, α-Nai Yisuanna 5-15 part mixes makes the coating feed composition, and d. gets granular urea that coating that 1 part of step c makes adds 100-500 part with feed composition and sends to and carry out coating after stirring in the coating machine, screening, packing.
Above-mentioned weight part can be g, kg, can also be other weight unit.
Above-mentioned granular urea can have been bought on market, is a kind of in the urea fertilizer.
Characteristics nontoxic, harmless, noresidue that above product all has more benefit farm crop and use.
The present invention has used the anion surfactant polyacrylamide, stablizer sal epsom, the dispersion agent Sodium dodecylbenzene sulfonate, the thickening material Xylo-Mucine, multiple SODIUMNITRATE of plant-growth regulator and root-growing agent Nafusaku, wherein the anion surfactant polyacrylamide can be adsorbed on the urea granules surface securely, form hydrophobic layer, prevent the urea moisture absorption, destroy the formation of " liquid bridge " and " brilliant bridge ", and stablizer sal epsom, the dispersion agent Sodium dodecylbenzene sulfonate, the thickening material Xylo-Mucine, multiple SODIUMNITRATE of plant-growth regulator and root-growing agent α-Nai Yisuanna then form a coating film on the urea granules surface, prevent the contact between the particle, and the intensity of increase urea granules, thereby play anti-caking and anti-atomizing good result; Sal epsom, Xylo-Mucine are thickening materials, Sodium dodecylbenzene sulfonate is a dispersion agent, α-Nai Yisuanna is a root-growing agent, sodium nitrophenolate is a plant growth regulators, the collaborative mutually decomposition rate of nitrogen that makes of Sodium dodecylbenzene sulfonate and sal epsom, Xylo-Mucine, α-Nai Yisuanna and sodium nitrophenolate needs nitrogen rule consistent with crop, can improve the utilization ratio of nitrogen in the urea, promote plant-growth simultaneously, satisfy the demand of crop magnesium; Experiment shows that this product fertilizer efficiency compares with common urea, can improve 15%-35%, can make wheat precocious 3-7 days, volume increase 8%-12%, early maturing of corn 4-7 days, volume increase 10%-15%, rice volume increase in precocious 4-6 days 10%-18%, so this product is the highly effective carbamide that a kind of many nutrition and preventing is lumpd, and technology is simple, cost is low, is fit to promote.
