Abstract
Способ получения смеси растворного и эмульсионного каучуков смешением раствора стереорегуляторного каучука с латексом эмульсионного каучука, введением в полученную эмульсию коагулирующего агента, дегазацией эмульсии, промывкой и сушкой смеси каучуков, отличающийся тем, что, с целью упрощения способа и улучшения физико-механических свойств резин на основе указанной смеси каучуков, смешивают раствор каучука с латексом каучука в соотношении 100 : 0,5 - 30, считая на каучук, и в качестве коагулирующего агента используют водный раствор соединения, выбранного из группы: неорганическая соль щелочного металла, неорганическая соль щелочноземельного металла, алифатический спирт, в количестве 5 - 50 мас.ч. соединения на 100 мас.ч. эмульсионного каучука, а дегазацию осуществляют при рН 7 - 9.The method of obtaining a mixture of mortar and emulsion rubbers by mixing a solution of stereoregulatory rubber with latex emulsion rubber, introducing into the resulting emulsion a coagulating agent, degassing the emulsion, washing and drying the mixture of rubbers, in order to simplify the method and improve the physicomechanical properties of rubber based on this mixture of rubbers, mix the solution of rubber with rubber latex in a ratio of 100: 0.5 - 30, counting on rubber, and use an aqueous solution of compound as a coagulating agent Ia, selected from the group of inorganic alkali metal salt, inorganic alkaline earth metal salt, an aliphatic alcohol, in an amount of 5 - 50 parts compounds per 100 wt.h. emulsion rubber, and degassing is carried out at pH 7 - 9.
