Abstract

Винахід належить до технології ізоляції труб. Ізоляція проводиться шляхом нанесення на трубу, що обертається, реакційної суміші ароматичного поліізоціанату, органічної сполуки молекулярної маси 92-1000, що має в середньому, щонайменше, три реакційноздатних щодо ізоціанатів атоми водню, аліфатичного, циклоаліфатичного або ароматичного поліаміну молекулярної маси 32-1000 в якості зшивального агенту і спінювального агенту, що використовується для виконання, щонайменше, одного ізоляційного шару жорсткого пінопласту, і подальшого нанесення покривного шару термопласту.
