Изобретение относитс  к составам дл  пок{иытн  гранулированных удобрений, в частности к составу дл  покрыпш г рану;пированБой мочевины, содержащему минеральное кгасдо, природный парафин, сиктетаческ й . и жирный ипи масл ный компонент.This invention relates to compositions for the production of granulated fertilizers, in particular, to a composition for pods; a mixture of urea containing mineral kg / kg, natural paraffin, syktetichesky. and fatty oil component.

Известен состав дл  покрыт1ш гранулированного удобрени , в том числе мочевины , включающий минеральное масло и твер дое растворимое в масле вещество, например воск, парафин flj. A composition for coating granulated fertilizer, including urea, is known, which includes mineral oil and solid oil-soluble substance, for example wax, flj paraffin.

Известен также состав дл  покрыти  гранупнрованной мочевины, coдepжaщv й минеральное масло, твердь й парафин иA composition for coating granulated urea, containing mineral oil, paraffin wax and

жирный или масл ный компонент 2J.fatty or oily component 2J.

Недостаток таких составов дл  покрыти  мочевины заключаетс  в том, что гранулированна  мочевина поглощает слишком sraoro влага при хранении в районах с высокой относительной влажностью. Так гигроскопичность указанных составов дл  покрыти  гранулированной мочевины составл ет не менее 7,О % после хранени  при 7О С в течение 24 ч и не менееA disadvantage of such compositions for coating urea is that granulated urea absorbs too much moisture when stored in areas of high relative humidity. Thus, the hygroscopicity of these compositions for coating granulated urea is not less than 7% O after storage at 7 ° C for 24 hours and not less than

15% после хранени  при 7О С в течение 4 мес цев.15% after storage at 7 ° C for 4 months.

Цепь изобретени  - уменьшение гигроскопичности мочевины.The chain of the invention is the reduction of the hygroscopicity of urea.

, Поставлепна  : цель достигаетс  тем, что и качестве твердого парафина состав содержит смесь из природного и синтетического парафина при следующем количественном соотношении компонентов, вес.Postavlepna: the goal is achieved by the fact that the quality of paraffin wax contains a mixture of natural and synthetic paraffin with the following proportion of components, weight.

Предложенный состав получают следующим образом.The proposed composition is obtained as follows.

Температура твердени  расплавленных парафинов зависит от содержани  синтетического парафина, т.е. чем больше синтетического парафина, тем выше температура смещени  расплавленных парафинов. с остальными компонентами. Приме р. Гранулы мочевины с температурой 70 С, приготовленные способом отверждени  расплава мочевины разбрызгиванием, покрывают распылением 5 различными составами в количестве 0,8% от веса гранул мочевины во в{эащающем- барабане. Покрытые таким образом гранулы хран т при температуре примерно 70 С в течение 24 ч и 4 мес цев. Затем определ ют гигроскопичность гранул при и относительной влажности воздуха 80 % в течение 24 ч, Используемые конкретные составы и данные по гигроскопичности даны в таблице .Natural and synthetic paraffin are disassembled at 9 ° -12 ° C and then mixed with mineral oil and fatty INN masses for the component at a temperature above, preferably by 10 ° -20 ° C, the temperature at which the melted paraffins mb solid. The hardening temperature of the molten paraffins depends on the content of synthetic paraffin, i.e. the more synthetic paraffin, the higher the temperature of the melted paraffins displacement. with the rest of the components. Primer p. Urea granules with a temperature of 70 ° C, prepared by spraying the urea melt by spraying, are sprayed with 5 different compositions in an amount of 0.8% of the weight of the urea granules in an external drum. The granules so coated are stored at about 70 ° C for 24 hours and 4 months. Then, the hygroscopicity of the granules is determined at a relative air humidity of 80% for 24 hours. The specific formulations used and the hygroscopicity data are given in the table.
