Из уровня техники известны подобные составы для защиты нефте- и газо- проводов, например, состав, содержащий привитый полиэтилен - US 20110318517 (публикация US 0008247053 21.08.2012 В2) - прототип.The prior art similar compositions for protecting oil and gas pipelines, for example, a composition containing grafted polyethylene - US 20110318517 (publication US 0008247053 08.21.2012 B2) - prototype.
Задача изобретения - улучшение адгезионных характеристик.The objective of the invention is the improvement of adhesive characteristics.
Задача решается тем, что разработан состав термопластичного адгезива, содержащий 15-30 мас.ч. полиэтилена средней плотности, привитый малеиновым ангидридом с содержанием привитого малеинового ангидрида - не менее 1,5 мас.ч. базовый полимер на основе линейного полиэтилена низкой плотности 40-85 мас.ч., эластомер на базе аморфных альфа-олефинов, бутилакрилата, стирольного термоэластопласта или этиленпропиленового каучука 5-30 мас.ч.The problem is solved in that a composition of a thermoplastic adhesive is developed containing 15-30 parts by weight medium density polyethylene grafted with maleic anhydride with a content of grafted maleic anhydride - at least 1.5 parts by weight base polymer based on linear low density polyethylene 40-85 parts by weight, elastomer based on amorphous alpha olefins, butyl acrylate, styrene thermoplastic elastomer or ethylene propylene rubber 5-30 parts by weight
Кроме того, состав дополнительно может содержать целевые добавки в количестве 0,01-10,00% массы полиэтилена.In addition, the composition may further contain targeted additives in an amount of 0.01-10.00% by weight of polyethylene.
Разработка технологии производства адгезивов для 3-х-слойной изоляции производилась с использованием оборудования НТЛ ЗАО «Метаклэй», а именно:The development of the technology for the production of adhesives for 3-layer insulation was carried out using NTL equipment of CJSC Metaclay, namely:
Использовалась экструзионная линия MKS 30 BUSS со стренговой грануляцией, вакуумированием, сухой (порошки, гранулы) и жидкой дозацией.We used the MKS 30 BUSS extrusion line with strand granulation, evacuation, dry (powders, granules) and a liquid dosage.
Рецептуры разрабатывались и тестировались на партиях 3-5 кг.The formulations were developed and tested on batches of 3-5 kg.
Пример №1 Рецептура адгезива для 3-х слойной изоляции труб ЗАО «Метаклэй» приведен в Таблице 1 (количество компонентов, указанное в масс.% соответствует количеству в масс.ч.).Example No. 1 The adhesive formulation for 3-layer insulation of pipes of CJSC Metaclay is shown in Table 1 (the number of components indicated in wt.% Corresponds to the amount in wt.).
Предварительно, полиэтилены MDPE, LLDPE и ЕВА смешивались и вводились дозатором через основной загрузочный порт.Previously, the polyethylene MDPE, LLDPE and EVA were mixed and introduced by the dispenser through the main loading port.
Пример №2. (сравнительный).Example No. 2. (comparative).
Рецептуры адгезивов для изоляции труб приготовленных в Германии (BYK-Kometra GmbH). Рецептуры готовились по рекомендациям Разработчика ЗАО «Метаклэй».Formulations of adhesives for insulation of pipes prepared in Germany (BYK-Kometra GmbH). The formulations were prepared according to the recommendations of the Developer ZAO Metaclay.

Сравнение адгезивов ЗАО «Метаклэй» с использованием собственного графт сополимера Метален MDPE-g-MAH и адгезивов, произведенных компанией BYK/Kometra GmbH с использованием собственных графт-сополимеров SCONA, приведено в Таблице 3.A comparison of the adhesives of CJSC Metaclay using its own graft copolymer Metalen MDPE-g-MAH and adhesives manufactured by BYK / Kometra GmbH using its own graft copolymers SCONA are shown in Table 3.
Образцы термопластичных адгезивов были протестированы в Лаборатории модификации полимеров НИИСПМ им. Ениколопова, в ЦЗЛ ЗАО «Метаклэй», в компании BYK/Kometra GmbH (Германия).Samples of thermoplastic adhesives were tested at the Polymer Modification Laboratory of NIISPM named after Yenikolopova, in the Central Laboratory of Clinics of CJSC Metaclay, in the company BYK / Kometra GmbH (Germany).
Спектральный анализ FTIR произведен в НТЛ ЗАО «Метаклэй»FTIR spectral analysis was performed at NTL CJSC Metaclay
Заявленный адгезив можно получать технологией, обеспечивающей беспрерывное производство такого композита на производительности не менее 500 кг/час.The claimed adhesive can be obtained by technology that ensures the continuous production of such a composite at a productivity of at least 500 kg / h.
Заявленные адгезивы ЗАО «Метаклэй», произведенные на базе собственного графт-полимера Метален (MDPE-g-MAH) по реологическим характеристикам, находятся на уровне, а по адгезионным характеристикам превосходят известные адгезивы, например, произведенные на базе графтов Scona BYK/Kometra, а также и целевой аналог Borcoat ME 0420.The declared adhesives of Metaklei CJSC, produced on the basis of the proprietary Metallen graft polymer (MDPE-g-MAH) in terms of rheological characteristics, are at a level that is superior to known adhesives, for example, those made on the basis of Scona BYK / Kometra grafts, and also the target counterpart to Borcoat ME 0420.
