Abstract
Description
Изобретение относится к адгезионным композициям на основе полиэтилена или сополимеров этилена с винилацетатом, используемым в качестве адгезивов при нанесении полимерного защитного покрытия на различные металлические поверхности.The invention relates to adhesive compositions based on polyethylene or copolymers of ethylene with vinyl acetate, used as adhesives in applying a polymer protective coating to various metal surfaces.
Заявленная композиция распространяется на наружное антикоррозионное полиэтиленовое покрытие стальных труб различного диаметра, предназначенных для строительства, реконструкции и капитального ремонта подземных и морских (подводных) газопроводов, нефтепроводов и водоводов.The claimed composition extends to the external anti-corrosion polyethylene coating of steel pipes of various diameters, intended for the construction, reconstruction and overhaul of underground and offshore gas pipelines, oil pipelines and water pipelines.
В качестве прототипа заявителем выбрана известная адгезионная композиция по патенту RU 2016040, состоящая из полиэтилена или сополимера этилена с винилацетатом, слюды молотой и модифицирующей добавки, при этом в качестве модифицирующей добавки она содержит олигомер 2,2,4-триметил 1,2-дигидрохинолина.As a prototype, the applicant selected the known adhesive composition according to patent RU 2016040, consisting of polyethylene or a copolymer of ethylene with vinyl acetate, ground mica and a modifying additive, while it contains a 2,2,4-trimethyl 1,2-dihydroquinoline oligomer as a modifying additive.
Одним из серьезных недостатков прототипа является его малая стойкость к катодному отслаиванию покрытия от металлической поверхности.One of the serious disadvantages of the prototype is its low resistance to cathodic peeling of the coating from a metal surface.
Задачей, на решение которой направлено заявленное изобретение является создание адгезионной композиции для противокоррозионной защиты металлических поверхностей и обладающей улучшенными свойствами, такими как повышенная адгезионная прочность и стойкость к катодному отслаиванию.The problem to which the claimed invention is directed is the creation of an adhesive composition for anticorrosive protection of metal surfaces and having improved properties, such as increased adhesive strength and resistance to cathodic peeling.
Техническим результатом является значительное улучшение качества защиты металлических поверхностей от коррозии.The technical result is a significant improvement in the quality of protection of metal surfaces from corrosion.
Технический результат достигается тем, что заявленная адгезионная композиция на основе полиэтилена или сополимера этилена с винилацетатом содержит 1-4 масс.% олигомера 2,2,4-триметил-1,2-дигидрохинолина, при этом согласно изобретению композиция дополнительно содержит 0,5-2,5 масс.% олигомера эпоксидных смол с молекулярной массой от 360 до 3500 и содержанием эпоксидных групп от 24 до 2 масс.%, 1-4 масс.% тройного сополимера винилацетата, винилверсатата и н-бутилакрилата и полиэтилен или сополимер этилена с винилацетатом - остальное.The technical result is achieved by the fact that the claimed adhesive composition based on polyethylene or a copolymer of ethylene with vinyl acetate contains 1-4 wt.% Of the oligomer of 2,2,4-trimethyl-1,2-dihydroquinoline, while according to the invention, the composition additionally contains 0.5- 2.5 wt.% Epoxy oligomer with a molecular weight of from 360 to 3500 and an epoxy content of 24 to 2 wt.%, 1-4 wt.% Of a ternary copolymer of vinyl acetate, vinyl versatate and n-butyl acrylate and polyethylene or a copolymer of ethylene with vinyl acetate - the rest.
В Таблице №1 указаны возможные примеры адгезионной композиции.Table No. 1 shows possible examples of the adhesive composition.
Полученная адгезионная композиция позволяет увеличить адгезионную прочность в зависимости от состава на 15-20% и стойкость к катодному отслаиванию на 45-70% по сравнению с прототипом.The resulting adhesive composition allows to increase the adhesive strength depending on the composition by 15-20% and the resistance to cathodic peeling by 45-70% compared with the prototype.
