Abstract
Способ получения твердых смазок для пары трения гребень колеса-рельс, включающий процессы смешения жидкой эпоксидной диановой смолы, отвердителя, пластифицирующей добавки, пропиленгликоля и антифрикционного порошка, с последующим формованием состава в стержни и бруски, отличающийся тем, что жидкую эпоксидную диановую смолу (А) переводят в твердый плавкий эпоксиуретан, содержащий свободные эпоксидные группы путем взаимодействия ее с ароматическим полиизоцианатом (Б) в результате совместного перемешивания при 80-120°С в течение 15-55 мин в соотношении А:Б от 80:20 до 96:4 и последующей выдержке в течение суток, а затем смешивают на вальцах при температуре 30-70°С в течение 10-30 мин полученный эпоксиуретан с пропиленгликолем, рубленым волокном и латентным отвердителем для эпоксиуретана и пропиленгликоля - 4,4'дифинилметандиизоцианатом блокированным диметиламином, после чего срезают в виде листа, сворачивают его в стержни и выдерживают 3 сут в складских условиях, при этом смазка содержит, мас.ч.: ! Эпоксиуретан100Пропиленгликоль6-70Блокированный изоцианат2-30Антифрикционный порошок20-500Рубленое волокно6-100A method of producing solid lubricants for a pair of wheel-rail friction pairs, including the processes of mixing liquid epoxy Dianova resin, hardener, plasticizing additives, propylene glycol and antifriction powder, followed by molding the composition into rods and bars, characterized in that the liquid epoxy Dianova resin (A) transferred to a solid fusible epoxyurethane containing free epoxy groups by reacting it with an aromatic polyisocyanate (B) as a result of joint mixing at 80-120 ° C for 15-55 min in s ratio A: B from 80:20 to 96: 4 and subsequent exposure during the day, and then mixed on rolls at a temperature of 30-70 ° C for 10-30 minutes, the resulting epoxyurethane with propylene glycol, chopped fiber and latent hardener for epoxyurethane and propylene glycol - 4,4'-diphenylmethanediisocyanate blocked with dimethylamine, and then cut off in the form of a sheet, roll it into rods and incubated for 3 days in storage conditions, while the lubricant contains, by weight:! Epoxyurethane 100 Propylene glycol 6-70 Blocked isocyanate 2-30 Antifriction powder 20-500 Chopped fiber 6-100
