ПЕРСПЕКТИВА ПРИМЕНЕНИЯ ОЛИГОМЕРА ИЗ ПОБОЧНЫХ ПРОДУКТОВ НЕФТЕХИМИИ, МОДИФИЦИРОВАННОГО ВТОРИЧНЫМ ПЕНОПОЛИСТИРОЛОМ ДЛЯ ЗАЩИТЫ ДРЕВЕСНЫХ МАТЕРИАЛОВ

Abstract

In the age of information technology and the age of polymers, there are more and more tasks in scientific researches on chemistry and chemical technology. Such a phenomenon is explained by the fact that humanity develops very quickly. Consequently, the needs are enhancing dramatically, and therefore everyone objectively understands that natural resources decrease annually. The time will come when nature will not be enough for human existence. To plant a tree is not to build a house, but the construction of a wooden house requires more than one tree that grows over the years. In this paper, the authors try to prolong the life of various products and materials made of cheap wood species by using waste from production, which may partially ensure the preservation of nature. The article presents the results on the use of oligomer from petrochemical waste for the protective treatment of wood materials and high-density fiberboard (HDF). The dosage of secondary expanded polystyrene to oligomer from polybutadiene by-products varies from 10 to 40 %. The obtained samples of fiberboard, birch, linden and aspen are examined for resistance to water and moisture. The results indicate that the samples have high strength properties and resistance to water and moisture. Thus, the integrated use of waste and by-products allows them to be disposed and to be used for protective treatment of wood products, which contributes to improving the formability and service life of products.
