0,8-2,0%-ный раствор низкомолекулярного полиэтилена (НМПЭ) в керосино-газойлевой фракции вторичных процессов с пределами кипения 195-270oС (техническая присадка "Недисс") - 60-50
Гудрон - 40-50
2. Способ приготовления профилактического средства, включающий получение 0,8-2,0%-ного раствора НМПЭ в керосино-газойлевой фракции вторичных процессов с пределами кипения 195-270oС путем смешения указанных компонентов при 80-90oC, затем полученный раствор в количестве 60-50 мас.% смешивается с гудроном в количестве 40-50 мас.%, далее смесь подвергается изотермической выдержке при 80-90oС в течение 30-90 мин, отличающийся тем, что предварительно производят смешение керосино-газойлевой фракции с НМПЭ.1. A prophylactic agent containing a kerosene-gas oil fraction of secondary processes with a boiling range of 195-270 o C, tar and low molecular weight polyethylene, characterized in that it contains components in the following ratio, wt.%:
0.8-2.0% solution of low molecular weight polyethylene (NMPE) in the kerosene-gas oil fraction of secondary processes with boiling limits of 195-270 o C (technical additive "Nediss") - 60-50
Tar - 40-50
2. A method of preparing a prophylactic agent, including obtaining a 0.8-2.0% solution of NMPE in the kerosene-gas oil fraction of secondary processes with a boiling point of 195-270 o C by mixing these components at 80-90 o C, then the resulting solution in an amount of 60-50 wt.% is mixed with tar in an amount of 40-50 wt.%, then the mixture is subjected to isothermal exposure at 80-90 o C for 30-90 min, characterized in that the kerosene-gas oil fraction is preliminarily mixed with NMPE.
