Abstract
Способ получения фрикционных полимерных материалов, включающий процесс обработки бутадиеновых или бутадиен-нитрильных каучуков на пластификационном оборудовании с последующим их смешением с вулканизирующими добавками и волокнистым наполнителем в сочетании с мелкодисперсным минеральным или металлическим порошком, отличающийся тем, что одновременно с вулканизирующими добавками вводится ароматический полиамин, представляющий собой анилино-формальдегидный конденсат, состоящий преимущественно из изомеров диаминодифинилметана и более высокомолекулярных анилино-формальдегидных продуктов, а волокнистый наполнитель (А) предварительно пропитывается водным раствором эпоксидной смолы (Б), представляющий собой продукт взаимодействия смеси диановой и алифатической эпоксидных смол с гликолями и их производными, в соотношении А:Б от 95:5 до 60:40, а затем сушится до влажности не более 1%, при этом материал содержит мас.ч.: ! Каучук 100 Ароматический полиамин 2÷20 Сера 1÷15 Тиурам 0,04÷2 2-меркаптобензтиазола 0,3÷4 Волокнистый наполнитель, пропитанный водорастворимой эпоксидной смолой 15÷100 Порошковый наполнитель 10÷100 A method of producing friction polymer materials, including the process of processing butadiene or nitrile butadiene rubbers on plasticizing equipment, followed by their mixing with vulcanizing additives and a fibrous filler in combination with finely divided mineral or metal powder, characterized in that aromatic polyamine is introduced simultaneously with vulcanizing additives, representing an aniline-formaldehyde condensate, consisting mainly of isomers of diaminodiphenylmethane and bo more high-molecular aniline-formaldehyde products, and the fibrous filler (A) is pre-impregnated with an aqueous solution of epoxy resin (B), which is the product of the interaction of a mixture of diane and aliphatic epoxy resins with glycols and their derivatives, in the ratio A: B from 95: 5 to 60 : 40, and then dried to a moisture content of not more than 1%, while the material contains parts by weight:! Rubber 100 Aromatic polyamine 2 ÷ 20 Sulfur 1 ÷ 15 Thiuram 0.04 ÷ 2 2-mercaptobenzthiazole 0.3 ÷ 4 Fiber filler impregnated with water-soluble epoxy resin 15 ÷ 100 Powder filler 10 ÷ 100
