Definitions

• the invention relates to a composite board with hydro-accumulation properties.
• One known embodiment of a board used in a roof structure comprises a mixture composed of recycled textile materials and primary textile material.
• the composite board composition results in a higher liquid retention capacity.
• recycled materials low cost and low carbon (COx) production is possible.
• COx low cost and low carbon
• This board was made by the technology of thermo bonding using bi-component fibres without use of chemical additives, on a production line allowing continuous production.
• a disadvantage of the current stat-of-the-art boards is that the boards are not flexible and shape-adjustable to the details of the construction requirements, they are unable to retain sufficient amount of fluid corresponding at least to the fluid weight of the same weight as the board for the period of 1 hour and they do not allow fluid transport in the cross section of the board depending on needed use.
• It aim of the present invention to is provide boards that have a hydro- accumulation effect similar to mineral or glass fibre boards, they are without chemical additives, but they also provide other advantages.
• the above-mentioned drawbacks are eliminated by the composite board with the hydro-accumulation properties as per the present invention, which is based in particular on the fact that it consists of 40-70% of crushed textiles, 20-40% of recycled polyester elements and 10-20% of binding fibres.
• the recycled polyester elements have a particle size from 1 to 40 mm, more preferably 15 mm. From the ecological point of view, it seems advantageous if the crushed textile is selected from the group consisting of crushed carpet textile, crushed filter textile or shredded filtration textile, and recycled polyester elements are selected from the group consisting of recycled polyester fibres or shredded structured fibres.
• Fig. 1 shows the structure of the composite board in section.
• the composite board according to Fig. 1 consists of 40-70% of crushed textiles 2, 20-40% of recycled polyester elements 1 with the size of 1 -40 mm and 10-20% of binding fibres 3.
• the composite board is manufactured using the technology of thermo-binding without use of chemical additives on a production line allowing continuous production; at first the crushed textiles and recycled polyester elements are ground, then the individual components are melted in an oven and bound in a press with pre-set final thickness of the composite board. Then the resulting material is cut into individual composite boards.
• ACjextensiv (80 kg m-2) average hydro-accumulation absorptive capacity of the tested set of samples - 8 pieces of tested samples from different manufacturing batches with load of 80 kg nrr 2 , corresponding to an extensive roof loading, in [l m 2 ]
• the heterogeneous structure of the multi-component input material allows for increased hydro-accumulation of the board under load. This characteristic is mainly ensured by the character of the input mixture composed of a matrix with a variable size of elements.
• the combination of different materials in the composite board contributes to its ability to accumulate rainwater and thus achieve the desired hydro-accumulation effect in the building industry, for example, in the realization of vegetation roofs, where the mean value of the absorption ranges for 20 - 30 mm of technical layers with 60 mm substrate from 22 to 28 I / m 2 .
• the spatial structure of the board allows the production of a board at least 1 cm high.
• the production technology enables the production of the product in various area weights in the range from 500 to 6000 g / m2, and in the form of not only boards but also rolls.
• the value of dynamic rupture by a cone for the thickness of 3 cm according to CSN EN ISO 13433 may be 0 mm.
• the invention of the hydro-accumulation fibre board, in particular of the retention board, is intended for roof structures, facade constructions or modifications of the details of structures in contact with the soil, where the aim is the rain water retention.
