Abstract
1. Способ получения наполненного бутадиен-стирольного каучука путем сополимеризации бутадиена со стиролом в эмульсии в присутствии радикальных инициаторов, стопперировании процесса, дегазации, введении антиоксиданта и наполнителей различной природы, выделении каучука из латекса методом коагуляции в присутствии коагулирующего агента и 2%-ного раствора серной кислоты, отмывку и сушку крошки каучука, отличающийся тем, что процесс коагуляции осуществляют в присутствии комбинированного коагулирующего агента, состоящего из 5-30%-ного раствора хлорида магния, вводимого в количестве 10,0-15,0 кг/т каучука, и волокнистого наполнителя, например, хлопкового, вискозного, капронового волокна или их смеси, вводимого в количестве 1,0-10,0 кг/т каучука.2. Способ получения наполненного бутадиен-стирольного каучука по п.1, отличающийся тем, что для приготовления комбинированного коагулирующего агента используют 5-30%-ный раствор хлорида кальция.1. A method for producing filled styrene-butadiene rubber by copolymerizing butadiene with styrene in an emulsion in the presence of radical initiators, stopping the process, degassing, introducing an antioxidant and fillers of various nature, isolating rubber from latex by coagulation in the presence of a coagulating agent and 2% sulfuric acid solution acid, washing and drying the rubber crumbs, characterized in that the coagulation process is carried out in the presence of a combined coagulating agent, consisting of 5-30% solution magnesium chloride, introduced in an amount of 10.0-15.0 kg / t of rubber, and a fibrous filler, for example, cotton, viscose, kapron fiber, or a mixture thereof, introduced in an amount of 1.0-10.0 kg / t of rubber. 2. The method of producing filled styrene-butadiene rubber according to claim 1, characterized in that a 5-30% solution of calcium chloride is used to prepare the combined coagulating agent.
