1. Способ получения магнийсиликатного проппанта, с полимерным покрытием, включающий подготовку исходных компонентов шихты, их помол, гранулирование, которое производят на воде, обжиг и рассев обожженных гранул, отличающийся тем, что магнийсиликатный проппант получают из дунита - природного сырья, помол которого осуществляют в три стадии: две сухие и одну мокрую с последующей сушкой, после чего проводят предварительный обжиг дунита при температуре 850-950°С, с последующим гранулированием на воде, содержащей органическое связующее, состоящее из 0,5-2,0 масс.% карбоксиметилцеллюлоза (КМЦ) и 3-5 масс.% триполифосфата натрия (ТПФН), сушкой и рассевом высушенных гранул с получением фракции гранулята 1,2-1,4 мм, далее проводят обжиг полученных фракций гранулята при температуре 1250-1400°С в течение 50-90 мин, после чего полученные фракции гранулята охлаждают и далее покрывают полимерным раствором, который наносят на обожженный гранулят с дозировкой 1,0-1,5г эпоксидианового полимера на 100 г гранулята, после чего проводят отверждение эпоксидианового полимера добавляя полиэтиленполиамин (ПЭПА) в количестве 10-20 % от массы полимера, затем гранулированное сырье сушат методом рассева гранул с получением фракции гранулята 1,6-1,8 мм.1. A method of producing a magnesium-silicate proppant, with a polymer coating, comprising preparing the initial components of the mixture, grinding them, granulating which is carried out on water, calcining and sieving the calcined granules, characterized in that the magnesium silicate proppant is obtained from dunite - a natural raw material, grinding of which is carried out in step three: two dry and a wet, followed by drying, followed by preliminary firing dunite at a temperature 850-950 ° C, followed by granulation in water containing an organic binder, consisting from 0.5-2.0 wt.% carboxymethyl cellulose (CMC) and 3-5 wt.% sodium tripolyphosphate (TPPN), by drying and sieving the dried granules to obtain a granulate fraction of 1.2-1.4 mm, then calcining obtained granulate fractions at a temperature of 1250-1400 ° C for 50-90 min, after which the obtained granulate fractions are cooled and then coated with a polymer solution, which is applied to the calcined granulate with a dosage of 1.0-1.5 g of epoxidian polymer per 100 g of granulate, after which carry out the curing of the epoxidian polymer by adding polyethylene polyamine (PEPA) to the 10-20% by weight of the polymer, then the granular feed is dried by granule sieving to obtain a granulate fraction of 1.6-1.8 mm. 2. Магнийсиликатный проппант, характеризующийся тем, что он получен способом по п.1.2. Magnesium silicate proppant, characterized in that it is obtained by the method according to claim 1.
