Definitions

• the application relates to a reinforcement for a material of a moldable mass. Reinforcements for malleable materials can also be provided from renewable materials. From DE 40 00 1 62 C2 is known about
• the object of the present invention is therefore to provide a reinforcement with which the materials obtain the required strength.
• the object of the invention is also to provide a building material with such a reinforcement and to specify a manufacturing method for the building material.
• a reinforcement for a material of a moldable mass is provided.
• the mouldable mass may in particular be a building material.
• the reinforcement are as components barley awns and parachutes of seeds, especially of cattail seeds, available.
• Cattails are often referred to in German-speaking countries with the scientific name Typha.
• the Flugn have stem fibers and of the
• the side fibers are often called Called side arms.
• the side fibers of the parachutes are connected to each other by the barley groves. It is important that the proportion by weight of the barley awns and the parachute is suitably coordinated.
• Weight portion is about 0.5 to about once as high.
• Barley awns have barbs from their natural design, in which the side fibers of the flying parachute can be jammed. This results in a connection of the side fibers with each other. It can be a connection of
• the barley groves are present in about 2 mm to about 4 cm long fragments. It has proved to be particularly favorable when the barley awns are present in about 4 to 8 mm long fragments. With these smaller fragments of barley awn, the resulting mesh structure of barley awn and parachute becomes more spatially effective and effective. In addition, this denomination of barley awns also facilitates the mechanical handling of such reinforced masses, since the usual screw conveyance would fragment longer particles in an uncomfortable manner by torsion.
• the stem fibers have a length of about 3 mm and / or the side fibers have a length of about 10 mm. It is understood that this length variations of about 50% of the given values are conceivable. Regarding the length of the stem fibers it has to be considered that the length of the seed is added.
• the stem fiber length results from a seed about 2 mm long and the adjoining bundle of fibers with a length of 2.5 mm. Of these branch about 8.5 mm long side fibers. Good results were achieved with these flying parachutes.
• the invention relates to a building material, such as a plaster mixture, with a reinforcement shown above.
• a building material such as a plaster mixture
• the requirement to build sustainable increases the demand for building materials with a high proportion of renewable raw materials. Therefore, building materials are required, especially plaster mixtures, with a reinforcement of biologically renewable raw materials, as shown above. Especially at
• Putzmischungen has been found that a reinforcement is quite significant. Putzmischungen without reinforcements or with insufficient reinforcement namely have the problem that can form cracks in the plaster when drying the plaster mixture after plastering the wet plaster mixture. These cracks are visually undesirable and sometimes interfere with the protective function of the plaster.
• the suitability and acceptance of a plaster mixture therefore depends crucially on the fact that no cracks occur during drying. In order to avoid cracks, it is often provided in the prior art to apply the plaster in several layers and / or to introduce a fabric into the plaster. This requires several operations, so that it is very advantageous to introduce a reinforcement in the plaster mixture to avoid cracking. A special aspect arises in listed buildings, since sometimes only a Putzlage may be applied, so that the alternative to apply several plaster mixtures, is not given.
• the building material is a plaster mixture containing clay.
• This may be, for example, a clay plaster.
• Loam is a mixture of sand, silt and clay. But there are also plasters with a very high clay content, so that is usually no longer spoken of a clay plaster. Even such plaster mixtures can be well reinforced with the reinforcement described here.
• the building material is a mineral plaster and / or a synthetic resin plaster. Such plasters are very widespread in the market and have positive properties with regard to long-term stability,
• the building material contains leaf particles of
• Cattail leaves In the foreground are the leaves of Typha angustifolia. By adding these leaves, the thermal insulation can be improved.
• Fly parrot is more likely to be Typha latifolia while the leaves are usually obtained from Typha angustifolia.
• a building material is to be selected.
• barley awns are to be provided.
• the barley awns are then mixed with the parachutes of seeds, in particular cattail seeds come into consideration.
• the proportion by weight of barley awns about 0, 1 to about twice as high as the weight fraction of Fluglechen.
• a mixture with the selected building material As a rule, mixing with a dry mix of the building material takes place.
• fragments of barley awn are present.
• fragments of barley awns are then used instead of the whole barley awn.
• An advantage of fragments in comparison to whole barley awns results for example in plaster mixtures that are thin to apply.
• whole barley awns would stand out visually undesirable.
• the fragments are enriched in the desired length by sieving. For example, arise in the above-mentioned educated crushing in awning crushers of combine harvesters
• the flying parachutes are made incapable of germination. This can be done by heating and / or irradiating the
• Figure 1 schematically shows three Flugnchen whose side fibers are connected to fragments of barley awns.
• FIG. 3 shows details of a barley awn.
• FIG. 1 shows three flying wings 1 of cattail seeds. These each have a trunk fiber bundle 2. From the parent fiber bundle 2 each branch off a plurality of side fibers 3. It should be noted that FIG. 1 is very schematic and, for example, does not show that the side fibers 3 also point downwards, ie in the direction of seed 5, as becomes clear from FIG. These side fibers 3, too
• FIG. 3 a single fragment 4 of a barley awn is shown.
• the fragments 4 of barley awns are so suitable for the connection of the side fibers 3, because their barbs have a shape in which the side fibers of the cattail seeds are easily jammed.
• the side fibers 3 connect through
