Abstract
Upgrade of the composition of cable PVC-compound grade I40-13A with aluminum hydroxide has been carried out. Fire resistance, thermophysical and physical-mechanical properties of the obtained compounds have been investigated. It is shown that the modernization of the composition of cable PVC compound with aluminum hydroxide enables production of a fi re-resistant compound. It was found that aluminum hydroxide significantly changes the thermophysical properties of cable plastic compound. In particular, heat generation and smoke generation during plastic compound combustion are significantly reduced. It has been established that the physical-mechanical and rheological characteristics of the cable compound modernized with aluminum hydroxide remain at the level of the original compound. The optimal amount of aluminum hydroxide for the modernization of cable plastic compound of the I40-13A grade is 10–15 wt.%.

Summary
Проведена модернизация состава кабельного поливинилхлоридного пластиката марки И40-13А гидроксидом алюминия. Установлено, что физико-механические и реологические характеристики кабельного пластиката при модернизации его состава гидроксидом алюминия остаются на уровне исходного компаунда. Ключевые слова: поливинилхлорид, пластикат, состав, модернизация, гидроксид алюминия, свойства Upgrade of the composition of cable PVC-compound grade I40-13A with aluminum hydroxide has been carried out. It was found that aluminum hydroxide significantly changes the thermophysical properties of cable plastic compound. В связи с этим целью настоящей работы является показать возможность модернизации состава промышленного кабельного ПВХ-пластиката марки И40-13А гидроксидом алюминия и создания компаунда с комплексом ценных свойств, которые отвечали бы современным требованиям к изоляционным материалам в кабельной промышленности. Для модернизации состава промышленного кабельного ПВХпластиката марки И40-13А использовали гидроксид алюминия (AI(OH) или Al2O3·3H2O), который используют в полимерной промышленности в качестве эффективного антипирена и наполнителя [10, 11].
