В последние годы популярность древесины и композитов на ее основе в качестве строительных материалов постоянно растет благодаря их доступности и простоте дальнейшей обработки. По данным Росстата, в 2020 г. были достигнуты рекордные показатели по строительству домов из древесины, составившие 9,35 млн м2. При этом древесина обладает высокой воспламеняемостью, что серьезно ограничивает ее применение в строительстве и других областях. В связи с этим исследования по ее огнезащите актуальны.</p></sec><sec><title>Цель и задачи</title><p>Цель и задачи. Исследовать огнезащитную эффективность вновь разработанных азотфосфорсодержащих огнезащитных составов (ОЗС) для древесины, полученных путем химической деструкции отходов полиэтилен­терефталата (ПЭТФ) с алифатическими аминами и без них.</p><p>Для достижения поставленной цели были определены следующие задачи:</p></sec><sec><title>1</title><p>1. Получить огнезащитные составы для древесины на основе азотсодержащих продуктов деструкции поли­этилентерефталата ди- и полиаминами и без присутствия ПЭТФ.</p></sec><sec><title>2</title><p>2. Изучить огнезащитную эффективность вновь полученных огнезащитных составов для древесины.</p></sec><sec><title>3</title><p>3. Сравнить огнезащитную эффективность огнезащитных составов, полученных с применением полиэтилентерефталата и без него.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Объектами исследования были огнезащитные составы для древесины на основе продуктов аминолиза полиэтилентерефталата алифатическими аминами. Метод заключался в определении потери массы образца древесины и времени самостоятельного горения при его испытании в установке «Керамическая труба».</p></sec><sec><title>Выводы</title><p>Выводы. Разработанные огнезащитные составы для древесины на основе продуктов химической деструкции отходов полиэтилентерефталата обладают высокой огнезащитной эффективностью. В качестве ОЗС для древесины наиболее целесообразно использовать композицию на основе ПЭТФ – ПЭПА.

In recent years, the popularity of wood and composites based on it as building materials has been steadily increasing due to their availability and ease of further processing. According to Rosstat data, in 2020, record figures for the construction of houses from wood were reached, amounting to 9.35 million m2. However, wood is highly flammable, which severely limits its use in construction and other applications. Therefore, research on its fire protection is relevant.</p></sec><sec><title>Aims and objectives</title><p>Aims and objectives. To investigate the fire-retardant efficiency of the developed nitrogen-phosphorus-containing fire-retardant compositions (FRC) for wood obtained by chemical degradation of polyethylene terephthalate (PET) waste with and without aliphatic amines.</p><p>In order to achieve the objective, the following tasks were defined:</p></sec><sec><title>1</title><p>1. To obtain fire-retardant compositions for wood based on nitrogen-containing degradation products of polyethylene terephthalate with di- and polyamines and without the presence of PET.</p></sec><sec><title>2</title><p>2. To study the fire-retardant efficiency of the newly obtained fire-retardant compositions for wood.</p></sec><sec><title>3</title><p>3. To compare the fire-retardant effectiveness of fire-retardant compositions obtained with and without the use of polyethylene terephthalate.</p></sec><sec><title>Methods</title><p>Methods. The objects of the study were fire-retardant compositions for wood based on aminolysis products of polyethylene terephthalate by aliphatic amines. The method consisted in determining the mass loss of a wood specimen and the time of independent combustion when it was tested in the “Ceramic Tube” unit.</p></sec><sec><title>Result and Discussion</title><p>Result and Discussion. As a result of the conducted research, it was revealed that the obtained fire-retardant compositions based on the products of chemical destruction of polyethylene terephthalate at the consumption of more than 160 g/m2 belong to the first group of fire protection efficiency.</p></sec><sec><title>Conclusions</title><p>Conclusions. The developed fire-retardant compositions for wood on the basis of products of chemical destruction of polyethylene terephthalate waste have high fire-retardant efficiency. It is most expedient to use the composition based on PET – PEPA as FR for wood. It is established that the developed composition belongs to the first group of fire protection efficiency.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>огнезащитная эффективность</kwd><kwd>полиэтилентерефталат</kwd><kwd>химическая деструкция</kwd><kwd>алифатические амины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fire protection efficiency</kwd><kwd>polyethylene terephthalate</kwd><kwd>chemical destruction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Albert Ch.M., Liew K.Ch.
