Abstract
The invention relates to producing organic polymer reticular foamed plastics which can be used in production. The inventive collagenic reticular foamed plastic has a directed structure. A method for producing collagenic reticular directed structure foamed plastic consists in using an initial system embodied in the form of a system comprising at least two components, one of which is water and the other component is collagen dissolved therein, in cooling the initial system to a temperature of the transition thereof into a solid aggregative state in such a way that formed crystals are substantially oriented in the same direction, in tempering the solid system during a time required for forming a polymer jelly-like microphase and in removing water.
Description
Коллагеновый ретикулярный поропласт направленной структуры и способ его получения Collagenic reticular poroplast directed structure and method for its preparation
Предлагаемое решение относится к технологии получения органополимерных ретикулярных поропластов, которые могут применяться для производства теплоизоляцонных, звукопоглощающих, шумоизолирующих и фильтрующих материалов, а также различного типа сорбентов и катализаторов. Ретикулярные полимерные поропласты представляют особый класс пористых полимерных материалов, газоструктурные элементы которых лишены граней, а полимерная фаза сосредоточена главным образом в ребрах их геометрически сложной структуры.The proposed solution relates to a technology for the production of organopolymer reticular poroplastics, which can be used for the production of heat-insulating, sound-absorbing, noise-insulating and filtering materials, as well as various types of sorbents and catalysts. Reticular polymer poroplasts represent a special class of porous polymer materials, the gas-structural elements of which are devoid of faces, and the polymer phase is concentrated mainly in the edges of their geometrically complex structure.
Известно два основных способа получения ретикулярных поропластов. Первый основан на разрушении граней газоструктурных элементов обычного поропласта, при котором более плотные ребра сохраняют свою целостность. Так, известен способ, согласно которому ретикулярный поропласт получают в результате гидролитической обработки пенопласта водным раствором щелочи.Two main methods for producing reticular poroplasts are known. The first is based on the destruction of the faces of gas-structural elements of a conventional porous plastic layer, in which denser ribs retain their integrity. Thus, a method is known according to which reticular foam is obtained as a result of hydrolytic treatment of a foam with an aqueous alkali solution.
В определенных условиях гидролитическому разрушению подвергаются относительно тонкие грани, а не ребра газоструктурных элементов. Известно проведение ретикуляции с помощью высокотемпературной (огневой) обработки, при которой грани поропласта расплавляются, и как структурный элемент исчезают.Under certain conditions, relatively thin faces, rather than edges of gas-structural elements, undergo hydrolytic destruction. It is known to carry out reticulation using high-temperature (fire) processing, in which the faces of the foam melt and disappear as a structural element.
Недостатком описанных способов является достаточно жесткое воздействие на поропласт, в результате которого возможно разрушение других элементов структуры. Вторая группа методов, предусматривает образование ретикулярной структуры непосредственно в процессе получения поропласта. Известен ряд способов, согласно которым ретикулярные поропласты получают путем введения в состав реакционной смеси инертного органического растворителя, веществ подавляющих пенообразование, а также химической модификацией реагирующих компонентов.The disadvantage of the described methods is a rather severe effect on the foam, as a result of which the destruction of other structural elements is possible. The second group of methods involves the formation of a reticular structure directly in the process of producing a poroplast. A number of methods are known, according to which reticular poroplasts are obtained by introducing an inert organic solvent, substances that suppress foaming into the composition of the reaction mixture, and also by chemical modification of the reacting components.
Однако и эти методы характеризуются рядом недостатков, к которым можно отнести сложность технологического процесса , а также использование дорогостоящих и в ряде случаев токсичных химических реагентов.However, these methods are also characterized by a number of disadvantages, which include the complexity of the process, as well as the use of expensive and in some cases toxic chemicals.
Все вышеперечисленные способы известны автору из его практической работы, и он считает их общеизвестными для специалистов в данной области техники.
Однако, к сожалению, в ходе составления данной заявки им не был выявлен какой- либо конкретный печатный источник, где бы эти сведения излагались в явной форме, и который мог бы послужить ближайшим аналогом. Несмотря на разнообразие применяемых методов, ретикулярные поропласты имеют близкое строение и поэтому характеризуются общими недостатками, находящими отражение в их физико-механических, а также газо- и гидродинамических характеристиках. Радикального изменения свойств ретикулярных поропластов можно достичь путем ориентации их структуры. Возникающая при этом анизотропия существенным образом сказывается на всем комплексе свойств поропластов, приводя, в частности, к их значительному упрочнению и увеличению проницаемости структуры в направлении ориентации. Коллагеновые ретикулярные поропласты с ориентированной структурой и методы их получения не известны.All of the above methods are known to the author from his practical work, and he considers them generally known to specialists in this field of technology. However, unfortunately, during the preparation of this application, he did not identify any specific printed source, where this information was stated in explicit form, and which could serve as the closest analogue. Despite the variety of methods used, reticular poroplasts have a similar structure and therefore are characterized by common shortcomings, reflected in their physicomechanical, as well as gas and hydrodynamic characteristics. A radical change in the properties of reticular poroplasts can be achieved by orientation of their structure. The anisotropy that arises in this case significantly affects the entire complex of properties of poroplasts, leading, in particular, to their significant hardening and increase in the permeability of the structure in the orientation direction. The collagenic reticular poroplasts with oriented structure and methods for their preparation are not known.
Целью настоящего изобретения является создание коллагеновых ретикулярных поропластов, имеющих ориентированную структуру, и разработка способа их получения.The aim of the present invention is the creation of collagenic reticular poroplasts having an oriented structure, and the development of a method for their preparation.
Поставленная цель достигается тем, что: -в качестве исходной используется система состоящая как минимум из двух компонентов, один из которых представляет собой кристаллизующуюся при понижении температуры жидкость (воду), а второй - растворенный в ней коллаген, способный в условиях существования кристаллов жидкости образовывать под действием физических или химических факторов макроскопическую гелеобразную фазу; процесс формирования ориентированного ретикулярного поропласта существляют путем охлаждения исходной системы до температуры ее перехода в твердое агрегатное состояние так, чтобы формирующиеся при этом кристаллы были ориентированы преимущественно в одном направлении, выдерживании отвержденной системы, в течение времени, необходимом для образования полимерной гелеобразной макрофазы и удалении жидкости (воды). В результате получают ориентированный ретикулярный поропласт, газоструктурные элементы которого повторяют форму и ориентацию кристаллов жидкости.
Ориентированная кристаллизация жидкости, являющейся, по существу, растворителем или дисперсионной средой, возможна при условии, что теплообмен системы с окружающей средой происходит преимущественно в одном направлении. При этом образующиеся кристаллы жидкости всегда ориентируются перпендикулярно поверхности охлаждения.This goal is achieved by the fact that: as the initial system is used consisting of at least two components, one of which is a liquid (water) crystallizing at lower temperatures, and the second is collagen dissolved in it, capable of forming under liquid crystals the action of physical or chemical factors, a macroscopic gel phase; the process of forming an oriented reticular poroplast exists by cooling the initial system to the temperature of its transition to a solid state of aggregation so that the crystals formed in this case are oriented mainly in one direction, maintaining the cured system for the time necessary for the formation of a polymer gel-like macrophase and removal of liquid ( water). The result is an oriented reticular poroplast, the gas-structural elements of which repeat the shape and orientation of the liquid crystals. Oriented crystallization of a liquid, which is essentially a solvent or dispersion medium, is possible provided that the heat exchange of the system with the environment occurs predominantly in one direction. In this case, the formed liquid crystals are always oriented perpendicular to the cooling surface.

Кювету помещают на охлажденную до -20°C полку плиточного скороморозильного аппарата на 20 минут, в течение которых происходит отверждение раствора с образованием кристаллов воды, ориентированных в основном перпендикулярно поверхности охлаждения (дна кюветы). Систему выдерживают в течение 20 часов при температуре -12°C, размораживают при комнатной температуре, обезвоживают прессованием и высушивают.An aqueous solution of collagen with concentrations of 3% is poured into a flat cuvette measuring 400 x 400 x 5 mm, the bottom of which is made of an aluminum sheet with a thickness of 0.5 mm and the walls of Teflon with a thickness of 10 mm. The cuvette is placed on a shelf of a tiled quick-freezing apparatus cooled to -20 ° C for 20 minutes, during which the solution solidifies with the formation of water crystals oriented mainly perpendicular to the cooling surface (bottom of the cuvette). The system is incubated for 20 hours at a temperature of -12 ° C, thawed at room temperature, dried by pressing and dried.
