Abstract

The invention relates to the field of layered materials used in construction, e.g. for waterproofing. The aim of the invention is to improve the operational qualities of the material by stabilising its temperature parameters. The material comprises a number M = 2n + 1 layers, where n is the number of layers of polymeric thermoplastic films (1) situated between layers of thermo-reactive fibrous woven or nonwoven materials (2) partially buried in the polymeric thermoplastic films (1). The relative dimensions of the initial substances (1 and 2) satisfy the condition 2Hv > /Hp > /Hv, where Hv is the thickness of the fibrous substance and Hp is the thickness of the polymeric film. The thickness of the material itself and of the initial polymeric films conforms to the following relationship: Hp(1.4n+1) > /Hm > /Hp(n+0.5), where Hm is the thickness of the material. The temperature-related expansion of the material during a rise in temperature from -4 DEG C to +60 DEG C is less than 1 %.

Description

Изобретение относится к области слоистых материалов, используемых в строительстве, например, для гидроизоляционных работ.The invention relates to the field of layered materials used in construction, for example, for waterproofing works.

Известны слоистые гидроизоляционные материалы, используемые в строительстве, такие как эластостеклобит и аналогичные ему материалы [1]. Недостатком этих материалов является их текучесть при температуре +(40-60)°С, вследствие чего, летом под действием солнечного тепла происходит просачивание эластомера через структуру армирующей или дублирующей ткани, что ускоряет разрушении гидроизоляционного покрытия.Known layered waterproofing materials used in construction, such as elastoteklobit and similar materials [1]. The disadvantage of these materials is their fluidity at a temperature of + (40-60) ° С, as a result, in the summer, under the action of solar heat, the elastomer seeps through the structure of reinforcing or duplicating fabric, which accelerates the destruction of the waterproofing coating.

Наиболее близким к заявленному материалу является материал, описанный в [2] (прототип), который состоит из нескольких слоев волокнистого и полимерного вещества. Недостатком конструкции этого материала является появление температурной деформации при приклеивании его на горизонтальные или вертикальные гидроизолируемые поверхности.Closest to the claimed material is the material described in [2] (prototype), which consists of several layers of fibrous and polymeric substances. The disadvantage of the design of this material is the appearance of temperature deformation when gluing it on horizontal or vertical waterproofing surfaces.

Целью настоящего изобретения является улучшение эксплуатационных свойств материала путем стабилизации его температурных параметров.The aim of the present invention is to improve the performance properties of the material by stabilizing its temperature parameters.

Поставленная цель достигается тем, что слоистый комбинированный полимерноволокнистый материал, состоящий из волокнистых и полимерных веществ, выполнен из М=2п + 1 слоев, где п количество слоев полимерных термопластических пленок, размещенных между слоями частично погруженных в них термореактивных волокнистых тканых или нетканых веществ. При этом соотношение размеров исходных веществ удовлетворяет условию:This goal is achieved by the fact that the layered composite polymeric fiber material consisting of fibrous and polymeric substances is made of M = 2p + 1 layers, where n is the number of layers of polymer thermoplastic films placed between the layers of thermosetting fibrous woven or nonwoven substances partially immersed in them. The ratio of the sizes of the starting materials satisfies the condition:

2Hv>Hp>Hv, где Hv - толщина волокнистого вещества,2Hv> Hp> Hv, where Hv is the thickness of the fibrous substance,

Нр - толщина полимерной пленки, а толщина материала и исходных полимерных пленок находится в следующем соотношении:Hp - the thickness of the polymer film, and the thickness of the material and the original polymer films is in the following ratio:

Нр(1,4 n+1) > Hm > Нр (п + 0,5), где Hm - толщина материала.Hp (1.4 n + 1)> Hm> Hp (n + 0.5), where Hm is the thickness of the material.

Изобретение пояснено чертежами.The invention is illustrated by drawings.

На фиг. 1 представлена конструкция слоистого материала толщиной Нm, состоящего из М=3 слоев полимерной пленки 1 и тканого вещества 2, толщины которых соответственно равны Нр и Hv; на фиг.2 изображена структура тканого вещества 2, образующая ячейки, в которые заключена полимерная пленка 1 .FIG. 1 shows the construction of a laminate with a thickness of Hm consisting of M = 3 layers of a polymer film 1 and a woven substance 2, the thicknesses of which are respectively Hp and Hv; figure 2 shows the structure of the woven substance 2, forming cells, which enclose the polymer film 1.

В слоистом материале данной конструкции температурные расширения полимерной пленки 1 демпфируются погруженными в полимер с двух сторон термореактивными волокнами вещества 2. В результате такого демпфирования температурное удлинение образца материала длиной 0,1 м, выполненного из тканого материала, такого как марля медицинская и полиэтиленовой пленки, при изменении температуры окружающей среды от -4 до +60°С составило менее 1 %, в то время как линейное удлинение образца полимерной пленки, описанной в [3] в аналогичных условиях составило более 1 0%. Из этого следует, что линейное удлинение материала данной конструкции при нагревании определяется температурным расширением волокнистого вещества, образующего ячейки, в которые заключена полимерная термопластичная пленка. В общем случае волокнистое вещество может иметь тканую или нетканую структуру.In the layered material of this construction, the temperature expansions of the polymer film 1 are damped by the thermosetting fibers of the substance 2 immersed in the polymer from both sides. As a result of this damping, the temperature elongation of a sample of material 0.1 m long, made of woven material such as medical gauze and plastic film, the change in ambient temperature from -4 to + 60 ° С was less than 1%, while the linear elongation of the polymer film sample described in [3] under similar conditions was more than 1 0%. From this it follows that the linear elongation of the material of this structure when heated is determined by the temperature expansion of the fibrous substance forming the cells in which the polymer thermoplastic film is enclosed. In general, the fibrous substance may have a woven or non-woven structure.

Применение материала данной конструкции в гидроизоляционных покрытиях, подвергающихся влиянию всесезонных атмосферных воздействий, позволяет повысить его прочность и долговечность эксплуатации.The use of material of this design in waterproofing coatings exposed to all-weather atmospheric influences, allows to increase its strength and durability of operation.
