Abstract
Description
Изобретение относится к технике переработки отходов полиуретана, в частности к получению из отходов полиуретана конструкционной пластмассы для формирования литьем под давлением комплектующих деталей изделий бытового назначения - ремешков наружных часов. The invention relates to techniques for the processing of polyurethane waste, in particular to the production of structural plastic from polyurethane waste for forming, by injection molding, components of household products - watch straps.
Известно использование отходов полиуретана в качестве сырья для производства лаков заливочных материалов, пленок олигомерных продуктов [1]. It is known to use polyurethane waste as a raw material for the production of varnishes for casting materials, films of oligomeric products [1].
Наиболее близким к заявляемому является композиция на основе вторичного полиуретана и технического углерода в виде гранул или крошки [2]. Closest to the claimed is a composition based on secondary polyurethane and carbon black in the form of granules or chips [2].
Однако при литье этой композиции наблюдается прилипание к пресс-форме, большая усадка, недостаточная твердость и прочность при разрыве. However, when casting this composition, sticking to the mold, large shrinkage, insufficient hardness and tensile strength are observed.
Отформованные детали имеют раковины, вздутия, утяжины, расслоения и высокое относительное удлинение. Molded parts have shells, bulges, weights, delamination and high elongation.
Цель изобретения - является улучшение литьевых свойств композиции при одновременном повышении прочностных характеристик. The purpose of the invention is to improve the casting properties of the composition while increasing strength characteristics.
Цель достигается тем, что композиция, включающая отходы производства термопластичного полиуретана и технический углерод, дополнительно содержит сополимер акрилонитрилбутадиена со стиролом и тальк при следующем соотношении компонентов композиции, мас.%:
Отходы производства
термопластичного поли- уретана 70-75 Технический углерод 0,7-1,5
Сополимер акрило-
нитрилбутадиена со стиролом 18-22 Тальк 4-7
Модификация полимера на основе отходов производства термопластичного полиуретана с АВС-пластиком в сочетании с наполнителем, позволяет получать конструкционный материал, предназначенный для формования литьем под давлением бытового назначения, в частности ремешков электронных наручных часов.The goal is achieved in that the composition, including waste from the production of thermoplastic polyurethane and carbon black, further comprises a copolymer of acrylonitrile butadiene with styrene and talc in the following ratio of the components of the composition, wt.%:
Waste production
thermoplastic polyurethane 70-75 Carbon black 0.7-1.5
Acrylic copolymer
nitrile butadiene with styrene 18-22 Talc 4-7
Modification of a polymer based on waste from the production of thermoplastic polyurethane with ABC plastic in combination with a filler allows one to obtain a structural material intended for injection molding using household purposes, in particular electronic watch straps.
Для экспериментальной проверки были изготовлены 14 составов (примеры 1-14) на основе отходов производства термопластичного полиуретана с АВС-пластиком и наполнителем с различным соотношением компонентов и 3 состава (примеры 15-17) при сочетании первичного термопластичного полиуретана (см. таблицу). For experimental testing, 14 compositions were made (examples 1-14) based on waste from the production of thermoplastic polyurethane with ABC plastic and filler with a different ratio of components and 3 compositions (examples 15-17) with a combination of primary thermoplastic polyurethane (see table).
Смесь компонентов - отходы производства термопластичного полиуретана (ТУ 17ССР 21-04-04-88) АВС-пластик (сополимер акрилонитрилбутадиенстирольный) ТУ 6-05-1587-84, углерод технический (ТУ 14-7-24-80) предварительно перемешивают в двухвалковой мельнице и сушат при 130-145оС с дозируемой подачей в расплав талька.A mixture of components - waste products from the production of thermoplastic polyurethane (TU 17SSR 21-04-04-88) ABC plastic (copolymer of acrylonitrile butadiene styrene) TU 6-05-1587-84, technical carbon (TU 14-7-24-80) is pre-mixed in a double roll mill and dried at 130-145 about With a dosed feed into the melt of talc.
Выходящие из головки экструдера стренги охлаждают и гранулируют на станке для рубки стренг. The strands emerging from the extruder head are cooled and granulated on a strand chopping machine.
В таблице представлены составы на основе отходов производства термопластичного полиуретана АВС-пластиком и тальком (примеры 5-8) позволяет повысить твердость, прочность при разрыве, технологичность при переработке, улучшить качество отливок, снизить до оптимальной величины относительное удлинение и усадку. При этом отходы термопластичного полиуретана приобретают свойства конструкционной литьевой пластмассы с определенным комплексом упругоэластичных свойств, необходимых для ремешков наручных часов. The table shows the compositions based on the waste from the production of thermoplastic polyurethane with ABC plastic and talc (examples 5-8) can increase the hardness, tensile strength, processability during processing, improve the quality of castings, reduce the elongation and shrinkage to the optimum value. At the same time, the waste of thermoplastic polyurethane acquires the properties of structural injection molded plastic with a certain set of elastic properties necessary for watch straps.
При сочетании первичного термопластичного полиуретана с АВС-пластиком и наполнителем (примеры 15-17) наряду с улучшением прочностных свойств материала, значительно возрастает твердость по Шору до 96 у.е., приводящая к потере его гибкости, что неприемлемо для таких упругоэластичных изделий, как ремешки наручных часов. When combining primary thermoplastic polyurethane with ABC plastic and filler (examples 15-17), along with an improvement in the strength properties of the material, Shore hardness significantly increases to 96 cu, resulting in a loss of its flexibility, which is unacceptable for such elastic products watch straps.
