Abstract
Description
Изобретение относится к технологии получения полимерного комплекса оксида цинка из поливинилового спирта (ПВС) и оксида цинка и может быть использовано при изготовлении биоцидных покрытий.The invention relates to a technology for producing a polymer complex of zinc oxide from polyvinyl alcohol (PVA) and zinc oxide and can be used in the manufacture of biocidal coatings.
Известно использование оксида цинка в составе антисептических средств (1. Лекарственные средства - Машковский М. Д. - М.: Медицина, 1998 г. - Том 2). Предполагается существование комплекса поливинилового спирта с гидроксидом цинка либо гидратированным оксидом цинка (2. И.Ю. Просанов, Н.В. Булина, К.Б. Герасимов. Комплексы поливинилового спирта с нерастворимыми неорганическими соединениями. Физика твёрдого тела. 2013. Т. 55, № 10, С. 2016). Однако структура этого комплекса является предположительной, его стехиометрия неизвестна. Данное техническое решение выбрано в качестве прототипа. Комплексы ПВС с гидроксидом цинка в известном техническом решении получают обработкой плёнок ПВС содержащих растворимые соли цинка щелочными растворами. Области применения не указаны.It is known to use zinc oxide in the composition of antiseptic agents (1. Medicines - Mashkovsky MD - M .: Medicine, 1998 - Volume 2). The existence of a complex of polyvinyl alcohol with zinc hydroxide or hydrated zinc oxide is assumed (2. I.Yu. Prosanov, NV Bulina, KB Gerasimov. Complexes of polyvinyl alcohol with insoluble inorganic compounds. Solid State Physics. 2013. V. 55 , No. 10, S. 2016). However, the structure of this complex is speculative; its stoichiometry is unknown. This technical solution was chosen as a prototype. The complexes of PVA with zinc hydroxide in the known technical solution are obtained by treating PVA films containing soluble zinc salts with alkaline solutions. Applications are not specified.
Предлагаемый материал объединяет полезные свойства ПВС - биосовместимость и способность к пленкообразованию с биоцидными свойствами оксида цинка.The proposed material combines the useful properties of PVA - biocompatibility and film-forming ability with the biocidal properties of zinc oxide.
Задача, решаемая заявляемым техническим решением, заключается в получении комплекса оксида цинка с ПВС стехиометрического состава из раствора. The problem solved by the claimed technical solution is to obtain a complex of zinc oxide with PVA of stoichiometric composition from solution.
Поставленная задача решается благодаря тому, что заявляемый полимерный комплекс оксида цинка для создания биоцидных покрытий, полученный смешением водного раствора поливинилового спирта с водно-аммиачным раствором оксида цинка имеет стехиометрический состав 1 атом цинка на 8 атомов углерода.The problem is solved due to the fact that the claimed polymer complex of zinc oxide for creating biocidal coatings obtained by mixing an aqueous solution of polyvinyl alcohol with an aqueous ammonia solution of zinc oxide has a stoichiometric composition of 1 zinc atom per 8 carbon atoms.
Составы с меньшим содержанием цинка, полученные тем же способом, также являются его комплексами с ПВС.Compositions with a lower zinc content obtained by the same method are also its complexes with PVA.
Этот результат достигается получением комплекса оксида цинка с ПВС содержащего в своём составе 1 атом цинка на 8 атомов углерода.This result is achieved by obtaining a complex of zinc oxide with PVA containing 1 zinc atom per 8 carbon atoms.
Для достижения результата производится смешивание водно-аммиачного раствора оксида цинка с водным раствором ПВС. To achieve the result, an aqueous ammonia solution of zinc oxide is mixed with an aqueous solution of PVA.
Пример 1.Example 1.
Водный раствор ПВС с концентрацией 10% масс. при комнатной температуре добавляют к 1% водно-аммиачному раствору оксида цинка в соотношении 2,2 объёма раствора ПВС к не более чем 10 объёмам раствора оксида цинка. После высушивания раствора получают твёрдый полимерный комплекс с соотношением не более чем 1 атом цинка на 8 атомов углерода. Отсутствие избытка оксида цинка и других кристаллических фаз подтверждалось методом рентгеновской дифракции. An aqueous solution of PVA with a concentration of 10% of the mass. at room temperature, add to a 1% aqueous ammonia solution of zinc oxide in a ratio of 2.2 volumes of PVA solution to not more than 10 volumes of zinc oxide solution. After drying the solution, a solid polymer complex is obtained with a ratio of not more than 1 zinc atom per 8 carbon atoms. The absence of excess zinc oxide and other crystalline phases was confirmed by X-ray diffraction.
Пример 2.Example 2.
Получают аммиачный раствор ПВС с оксидом цинка как в примере 1. Затем, этот раствор прогревают, не доводя до кипения. При этом аммиак удаляется из раствора, часть полимерного комплекса оксида цинка осаждается из раствора. После высушивания раствора получают твёрдый полимерный комплекс.An ammonia solution of PVA with zinc oxide is obtained as in example 1. Then, this solution is heated without boiling. In this case, ammonia is removed from the solution, part of the polymer complex of zinc oxide is precipitated from the solution. After drying the solution, a solid polymer complex is obtained.
Полученные растворы могут быть использованы для нанесения в качестве антисептического, биоцидного средства на поверхности предметов, растения и кожу. The resulting solutions can be used for application as an antiseptic, biocidal agent on the surface of objects, plants and skin.
После высушивания раствора комплекса оксида цинка с ПВС получают плёнки, которые могут служить в качестве самостерилизующегося покрытия. After drying the solution of the zinc oxide complex with PVA, films are obtained that can serve as a self-sterilizing coating.
Достигаемый технический результат заявляемого изобретения заключается в получении гомогенного состава комплекса поливинилового спирта с оксидом цинка с содержанием в нём цинка равным или меньшим, чем 1 атом цинка на 8 атомов углерода.The achieved technical result of the claimed invention is to obtain a homogeneous composition of a complex of polyvinyl alcohol with zinc oxide with a zinc content equal to or less than 1 zinc atom per 8 carbon atoms.
