(54) МНОГОСЛОЙНОЕ ПЛЕНОЧНОЕ ПОКРЫТИЕ(54) MULTILAYER FILM COATING
Изобретение относитс к защитным покрыти м и может быть использовано дл защиты изделий от коррозии, например , .дл покрыти труб на магистральных трубопроводах.The invention relates to protective coatings and can be used to protect products from corrosion, for example, for coating pipes on main pipelines.
Известно антикоррозионное покрытие , состо щее из 2-х слоев пластмассовых пленок, например полиэтиленовых , чередующихс с 3-м сло ми смазки 1.A corrosion-resistant coating is known, consisting of 2 layers of plastic films, for example polyethylene, alternating with 3 layers of lubricant 1.
Недостатками этого покрыти вл ютс сложность применени дл изол ции труб в полевых услови х и низка производительность в св зи с необходимостью послойного нанесени покрыти .The disadvantages of this coating are the difficulty of applying for insulating pipes in field conditions and low productivity due to the need for layer-by-layer coating.
Известно также изол ционное покрытие дл металлических труб, уложенных в грунт, содержащее слой полимерной смеси, наход щийс между сло ми полиэтилена 2,It is also known to have an insulating coating for metal pipes laid in a primer containing a layer of polymer mixture between layers of polyethylene 2,
Недостатком известного покрыти вл етс низка коррозионна стойкость вследствие малого срока обеспечени механической прочности сцеплени полиэтиленовой пленки с металлической поверхностью, в св зи с чем в местах отслоени покрыти происходит интенсивное коррозирование мета.пла.A disadvantage of the known coating is low corrosion resistance due to the short period of ensuring the mechanical strength of adhesion of the polyethylene film to the metal surface, in connection with which intense corrosion of meta.pl occurs in places of peeling of the coating.
Цель изобретени - повышение антикоррозионных свойств покрыти .The purpose of the invention is to improve the anti-corrosion properties of the coating.
Цель достигаетс тем, что слой с наполнителем выполнен из тисненной полиэтиленовой пленки с чейками, заполненными невысьЬсающим антикоррозионным веществом.The goal is achieved by the fact that the layer with the filler is made of an embossed polyethylene film with cells filled with a non-rising anticorrosive substance.
На чертеже схематически показано предлагаемое покрытие.The drawing schematically shows the proposed coating.
Покрытие состоит из наружных слоев 1-и 2 из полиэтиленовой пленки и внутреннего сло 3, выполненного из тисненой полиэтиленовой пленки с чейками 4 глубиной 2-3 мм, заполненными невысыхающим антикоррозионным веществом 5.The coating consists of outer layers 1- and 2 of polyethylene film and the inner layer 3, made of embossed polyethylene film with cells 4, 2-3 mm deep, filled with non-drying anticorrosive substance 5.
Слои 1 и 3 соединены посредством кле , например марки № 88-Н.Layers 1 and 3 are bonded by means of glue, for example brand No. 88-H.
Слои 2 и 3 соединены посредством невысыхающего антикоррозионного ч вещества, содержащегос в чейках сло 3.Layers 2 and 3 are connected by means of a non-drying anticorrosive h of the substance contained in the cells of layer 3.
В качестве невысыхающего антикоррозионного вещества используют, например , тугоплавкую минеральную смазку с ингибитором М 97,7 вес.%, антиокислительной добавкой-ионом 0,05 вес.% и летучим ингибитором 0 бензонатом натри 2,25 вес.%.As a non-drying anticorrosive substance, for example, a refractory mineral lubricant with an inhibitor M of 97.7% by weight, an antioxidant additive ion of 0.05% by weight and a volatile inhibitor 0 sodium benzonate 2.25% by weight is used.
Слой 2 предназначен дл предохранени от вытекани из чеек невысыхеиощего антикоррозионного вещества и удал етс .в момент использовани покрыти .Layer 2 is intended to prevent the non-harsh anti-corrosion agent from escaping from the cells and is removed when the coating is used.
. многослойное пленочное покрытие при изготовлении сматывают в рулоны. При нанесении покрыти на трубы рулон постепенно разматывают, удал ют слой 2 и покрытие нанос т так, что слой антикоррозионного вещества прилегает непосредственно к поверхности трубы.. Multilayer film coating in the manufacture of coiled into rolls. When coating the pipes, the coil is gradually unwound, layer 2 is removed and the coating is applied so that the layer of anti-corrosion substance is directly adjacent to the surface of the pipe.
