Description

Non-combustible organic material

description

The invention relates to a non-combustible organic material, e.g. Wood shavings include, a molded component made of this material, as well as processes for the production and processing of the material.

Due to their advantageous properties, wood-based materials are widely used in the construction sector as well as in the furniture sector and in industry. In addition to the processing of construction wood, for example due to static requirements, wood chips, bamboo or the like are often used. Wood shavings, for example, are a by-product or waste product in the wood or woodworking industry. Wood shavings can, for example, be processed into chipboard or used loosely or as plates in thermal insulation. For thermal insulation, wood shavings, eg from spruce and fir wood and other woods, are processed into various insulating materials and building materials. Loose organic matter and fibers produced therefrom can be used as blown or bulk insulation or as sheet goods. Another use of panels is the combination of wood and cement, which, however, have a high specific gravity and a poor thermal property. However, without further treatment, these wood-based materials are not fire-resistant. In order to limit, slow down or prevent the spread of fires, it is possible to use flame retardants, which are generally highly toxic. These are mainly used in combustible materials and finished parts to meet fire safety requirements in construction and transport. Flame retardants are in the form of additive flame retardants, which are incorporated into the flammable substances as additives, or as coatings, in which the fire retardant is applied from the outside as a coating on the workpiece to be protected. Also known are reactive flame retardants and an inherent flame retardant.

A disadvantage of the use of flame retardants in conjunction with wood is that these flame retardants have very high toxic properties.

It is an object of the invention to provide a non-combustible material which has a high flame retardancy and overcomes the disadvantages described above,

Another object of the invention is to provide a non-combustible mold component which does not have the disadvantages described in the introduction.

Another object of the invention is to provide a method of manufacturing and a method of processing an organic material.

These objects are achieved by a material according to the features of claim 1, a molded component according to the features of claim 12 and a method of manufacturing according to the features of claim 20. Advantageous embodiments will be apparent from the respective dependent claims. An organic material is suggested which becomes non-combustible in that one or more organic substances are combined with water and one or more other inorganic materials to form a material which is moldable, castable, spreadable, etc., or is present in the form.

Such a material has a flame retardant for temperatures of up to 3200 ° C and more. The material is inexpensive to produce and recyclable. Since it has no toxins, it protects the environment and is sustainable. There are no emissions of any kind. The organic material consists of natural products, so that even in case of later recycling no special waste to be stored is produced. The high flame retardance requires no additional material treatments. Another advantage is that it has a high stability and shows no deformation even under high loads. Due to its ingredients, it is resistant to water and frost, resulting in high durability and durability. The fact that the materials of the material can be brought into a moldable composite material, there are wide applications. In particular, the organic material or substances in the composite material include organic vegetable matter, in particular wood, wood shavings (for example in the form of sawdust), wood flour, reeds, bamboo, straw, grasses, leaves, needles or mixtures thereof. In principle, any organic substances of the type mentioned above can be processed. Beech wood (or no major use in Europe) or softwoods have proved to be advantageous.

It has proven to be expedient if the organic substance or substances in the composite material occupy a volume fraction of between 30% by volume and 90% by volume. The lower the volume fraction of the organic substance (s), the harder the composite material is. It can be used eg in the construction sector for floor coverings (eg tiles). The larger the volume fraction of the organic or Fabrics the lighter the composite material. Thus, for example, applications in the automotive, aircraft or white goods offer.

For good bonding of the components of the composite material, it is expedient if this comprises quartz as an inorganic material. In addition, the addition of quartz provides high strength and stability of the cured composite. The hardness can be adjusted by the added amount of quartz. For example, alkali silicates of the formula M ₂ O.nSiO ₂ (where M corresponds to Na, K or Li and where n is the molar ratio), ie potassium silicate, soda water, lithium water glass or mixtures thereof, may be used as the quartz. In addition, potassium, sodium, silicon or lithium in the quartz used in each case can provide the composite material with electrically conductive properties. This can be exploited, for example, to create a Faraday cage or for direct powdering with plastics.

By adding hollow glass bodies, in particular in spherical form, and / or volcanic ash as filler (s), the composite material can be provided with heat-insulating and sound-insulating properties. Hollow glass bodies have a high insulating effect and are also very light. The composite material can be produced thereby with low weight. In addition, the hollow glass spheres provide, inter alia, for a sound reduction. It has proven to be expedient if the hollow glass body have a diameter between 5 μιη and 2 mm, in particular between 10 μιη and 200μιη. Conveniently, the volume fraction of the hollow glass body is at most 50% by volume. The larger the volume fraction of the hollow glass body, the easier the composite can be. By adding ashes it is also possible to influence the insulation properties and the flame retardancy properties. The volcanic ash can be used additive or as a substitute for the hollow glass body. Compared to hollow glass bodies, volcanic ash has a low price. If the volcanic ash has no cavity, moreover, a higher compressive strength than in some hollow glass bodies (this is of the diameter and the wall thickness of Hollow glass body dependent) given. The volcanic ash can also be provided in the form of hollow bodies. The volcanic ash expediently occupies a volume fraction of at most 50% by volume. The organic material may also be provided with thermally conductive properties when the composite is provided with an inorganic nitride. For example, boron nitride can be used as the nitride. Conveniently, the organic material occupies a volume fraction between 10% by volume and 60% by volume in order to meet a set requirement for the heat conduction.

In a further embodiment, the composite material comprises an additional fungicidal, bactericidal and algericidal preservative. As a preservative, e.g. Preventol, which is released by human medicine, can be used. Optionally, the composite may further comprise one or more of the following fillers: Nano-particles may be incorporated to provide permanent UV protection of the wood-based material. In order to achieve a surface hardness of the organic material after drying, corresponding inorganic substances can be used. In addition, as further fillers u.a. Cotton, textile waste, EPS beads or flakes, in particular smaller than 3mm, be used to produce the composite material.

A molded component according to the invention is characterized in that it is formed from an organic material of the type described above and / or below, wherein the composite material of the (wood) material is present in dried and hardened form.

The molding member may be a substantially planar member having two major sides, of which no major side, one of the major sides or both of the major sides have a three-dimensional surface structure. The mold component may thus have a plate shape. With its flat back, this one can be on easy Way attached to a carrier. On the main side facing away from the carrier, a three-dimensional surface structure which fulfills structural or merely aesthetic aspects can be provided. Basically, the wood material can be brought into any shape.

The molded component can be provided with the above properties in a very small thickness. As a lower limit, thicknesses of about 1 mm could be achieved. There is virtually no limit to the top. The molded component may also consist of one or more layers of the composite material. The layers may have the same or a different thickness. The layers may have the same or different fillers.

In order to achieve a particularly high strength of the molded component, this may comprise a reinforcement of metal and / or wood and / or glass fiber and / or carbon fiber and / or plastics, wherein the reinforcement is at least partially surrounded by the composite material. Due to the constituents of the composite, this metal and / or wood and / or glass fiber enters into an adhesive, non-destructive detachable connection. In contrast, it has been found that adhesion to plastic does not occur.

In order to further improve the surface hardness of the molded component, corresponding inorganic further substances may be applied to a surface, e.g. Aerosil. This can be applied to the surface by known technologies and / or by brushing, spraying, rolling, knife coating and the like.

The (wood) material or the molded part of the type described here can be used as fire protection for temperatures up to 3200 ° C. Another use of the wood material is to provide thermal insulation or, in other material composition, heat conduction. In addition, can the composite material can be used to dissipate electrical voltages, eg as a Faraday cage for lightning discharge.

The method according to the invention for the production of the material of the type described above comprises the following steps:

Providing the organic substance (s), water and at least one inorganic material; and

Mixing the organic substance or substances, the water and the at least one inorganic material into a composite material, whereby the material is provided. By providing the amount of water relative to the other components, the viscosity of the material thus provided can be easily adjusted.

As organics, vegetable organic matter, especially wood, wood chips (e.g., in the form of sawdust), wood flour, reeds, bamboo, straw, grasses, leaves, needles, or mixtures thereof, are provided and mixed. Hardwood or softwood have proven to be advantageous.

In a further embodiment, at least one filler (preservative, nanoparticles, aerosil, cotton, textile waste, expanded plastic beads or flakes) is additionally provided and added with the inorganic substance (s), the water and the at least one inorganic material the viscous composite material mixed. Prior to further processing, the composite that is in a viscous form after mixing may be subjected to a drying step until a desired viscosity of the composite is achieved.

The composite material thus provided can be processed directly and in particular in an endless form. Alternatively, this can be introduced into an airtight container, so that it has a virtually unlimited shelf life. In front the further processing, it may only be expedient to stir again or mix or dilute the stored composite material in the container.

The method according to the invention for processing the material as described above comprises according to a first variant the following steps:

Applying the composite to a surface to which a temporary or permanent connection is to be made;

- Drying of the composite on the surface.

The processing of the moldable composite can be done by spraying, trowelling, trowelling, chipping, pouring and / or the like. In general, the viscous composite material such as concrete, plaster, injection molding or plaster can be processed. The surface on which the composite material is to be applied can be a brick or concrete wall, a door, but also a metallic and / or mineral component, such as e.g. a wall of white goods, or generally a body component, e.g. Flap or bonnet, a means of transport (e.g., a motor vehicle, a train, an airplane, etc.) or a cowling. The composite can also be applied alone or directly to mineral or metallic or organic parts. Overall, a free-form composite material can be produced. The composite material can be applied in particular for heat dissipation or thermal insulation and also for machine parts, motors, electronic components and the like to be cooled. Also, a (full-surface) current dissipation is possible.

In an alternative variant, the method for processing the wood-based material comprises the following steps:

Introducing the composite into one or more layers into one

Shape of a molded component;

- drying the composite in the mold;

Further processing of the molded component removed from the mold. The mold is preferably made of a plastic, since the composite does not form a firm connection with this. The further processing of the molded component may comprise a fastening by direct application to a, in particular from fire, to be protected and / or insulating or heat-dissipating carrier by gluing, a screw, a Klet- device and the like. The attachment of the mold component, preferably in the form of a plate, can take place with or without an air gap to the carrier. The carrier may be, for example, a house wall made of brick, concrete and the like, provided that a fire and heat insulation is desired. For example, heat dissipation may occur in electronic devices such as a PC case, a transformer case, a motor, a tool, and the like. For heat dissipation, the molded component can be brought into the shape of a heat sink, for example.

The invention will be explained in more detail below with reference to exemplary embodiments in the drawing. 1 shows a schematic representation of a non-combustible material according to the invention;

Fig. 7 is a schematic representation of a second embodiment variant of a mold component according to the invention.

1 shows a schematic representation of the components of a non-combustible material 1 according to the invention. The non-combustible material comprises one or more organic substances 2 (eg vegetable organic substances such as wood, wood chips, wood flour, reeds, bamboo, straw, grasses, foliage, Needles or mixtures thereof), water (H ₂ O) 3, one or more inorganic materials 4 and optionally one or more fillers 5. The organic substance (s) 2 becomes one with the water 3 and the one or more further inorganic materials 4 moldable or molded composite material. The organic substance or substances 2 have a volume fraction of between 10% by volume and 90% by volume. The volume fraction of the organic substance (s) determines the weight of the composite. The lower the volume fraction of the organic substance (s), the heavier the composite material. It can be used eg in the construction sector for floor coverings (eg tiles). The larger the volume fraction of the organic substance (s), the lighter the composite material. Thus, for example, applications in the automotive, aircraft or white goods offer. Preferably, organic matter of about the same size and texture is used in the composite. Basically, the size or coarseness of the wood chips is not important, but specifies the subsequent optical and surface properties. The inorganic material or materials provide good bonding of the components of the composite. The optional fillers allow for the provision of composite materials of varying weight and / or strength. Fig. 2 shows an embodiment variant in which the non-combustible material 1 is a heat-insulating wood material. In addition to wood shavings as organic material 2 and the water 3, the wood material 1 comprises 4 quartz as inorganic material. Quartz may be used in the form of alkali metal silicates of the formula M ₂ O.nSiO ₂ (where M equals: Na, K or Li and where n is molar ratio), ie, potassium silicate, soda water, lithium water glass, or mixtures thereof. The quartz ensures high strength and stability of the hardened wood material. Due to the potassium, sodium or lithium in the quartz, the composite material can also be provided with electrically conductive properties, which can be used, for example, for voltage dissipation (Faraday cage). As fillers 5 may in the composite hollow glass body and / or volcanic ash (also called volcanic ash) may be included. The hollow glass body preferably have a diameter between 5 μιη and 2 mm, in particular between 10 μιη and 200 μιη, and are in spherical form. The volume fraction is at most 50%. Among other things, the percentage of hollow glass bodies on the composite determines the later heat-insulating properties and the weight of the wood material. The larger the volume fraction of the hollow glass body and / or the EPS beads, the lighter the composite material. Basically, the insulating effect increases with increasing proportion of hollow glass bodies and / or the EPS beads. The volcanic ash can be used additive or as a substitute for the hollow glass body. Compared to hollow glass bodies, volcanic ash has a low price. If volcanic ash without cavity is used, moreover, a higher compressive strength is possible than with some hollow glass bodies (this depends on the diameter and the wall thickness of the hollow glass body). The volcanic ash expediently occupies a volume fraction of at most 50% by volume. It can also be used volcanic ash with a cavity. Optionally, as a further filler, a fungicidal, bactericidal and algericidal preservative may be added to the composite. As a preservative For example, Preventol, which has been approved by human medicine, can be used. If the composite material 6 should have UV protection, nanoparticles may optionally be added as a filler. The surface hardness can be increased by the addition of Aerosil, A1 ₂ 0 ₃ , SiC, boron nitride or Si0 ₂ . These substances can be added thereto as a component to be mixed to the other components mentioned. As further fillers cotton or textile waste as well as styrofoam beads or flakes, in particular smaller than 3 mm, can be used. After mixing the above-mentioned ingredients, the composite material 6 is in viscous form, wherein the viscosity depends on the percentage of water or quartz.

FIG. 3 shows an alternative of a non-combustible, heat-dissipating wood-based material. In addition to wood shavings as organic matter 2, water 3, as inorganic materials, quartz and a thermally conductive material, such as quartz, are used. Boron nitride, mixed together. Optionally, the fillers mentioned in the description of FIG. 2 can be added. The wood chips have, as in the previous embodiment, a volume fraction of between 10% by volume and 90% by volume. The nitride (s) occupy a volume fraction of between 10% and 60% by volume.

The mixing of the components mentioned occurs in both wood materials at room temperature. A desirable or undesirable drying process may be accelerated or slowed down by the temperature during processing. The viscosity of the wood material can be adjusted by the proportion of water.

Should it be necessary or desired, the composite material may be colored during mixing of said components. It is also possible to apply paint to the cured and dried composite material after completion of the drying process. The viscous wood material can be processed in a similar way to concrete or plaster. This means that the wood material is sprayable, stickable or can be applied to a surface with a trowel. As a result, shaping in the viscous state of the composite material is possible in particular. The viscosity of the wood material can be further processed by a casting process or an extrusion process. As a result, any shapes for three-dimensional parts can be achieved. It should be noted that during the drying process almost no shrinkage occurs, so that a high dimensional stability is maintained.

Fig. 4 shows the manufacturing and processing process of the present in viscous form material. In a step S1, the organic substance (s) 2, for example the wood chips described above, the water 3 and the inorganic material (s) 4 are optionally provided with the addition of one or more fillers 5 and mixed into the composite material in a step S12 , As described, mixing takes place, for example, at room temperature. By adding the amount of water 3, the viscosity of the composite can be controlled. In an optional step S13, a predrying process may be performed to a desired viscosity of the composite. If no immediate processing is desired, the viscous material may be stored airtight in a container or container in a step S14. Alternatively, the viscous material may be sprayed, spatulated or stuccoed directly onto a surface (eg, a house wall, a door, a wall of white goods, a body component of a vehicle, a cowling, a machine part to be cooled, a motor, a motor, etc.) according to step S15 electronic component) are applied. Alternatively, the viscous composite may be subjected to a casting process or extrusion. Subsequently, in step S16, drying takes place on the surface to which the composite is to be bonded or in the form in which composite material has been introduced. The drying process, in particular the duration of the drying process, makes it possible to measure the surface roughness of the Adjust composite material, as this is influenced by the evaporation rate of the water and thus the duration of the drying process.

5 shows the schematic sequence of the method for the production and processing of the material as a molded component. According to step S21, the organic substance (s) 2, eg the wood chips, the water 3 and the inorganic material (s) 4, optionally the fillers 5, are provided and mixed into the composite material according to step S22. In step S23, the introduction of the viscous composite material in a mold, in particular made of plastic. In step S24, the composite is dried in the mold. The drying process can be accelerated by C0 ₂ and the level of temperature and / or negative pressure. According to step S25, the mold component is removed from the mold after the composite has completely dried and cured. Optionally, after removal on at least one surface of the molded component Aerosil, A1 ₂ 0 ₃ , SiC, boron nitride or Si0 ₂ can be applied in order to further increase the surface hardness. Subsequently, according to step S26, further processing of the molded component takes place.

The material also enables the realization of layered structures with different physical material properties. For example, to produce a molded component in the mold, first a first layer having a first thickness and a first combination of materials (eg a particularly high proportion of hollow glass bodies) can be filled in and dried. In a second operation, a second layer having a second thickness and a second material combination (eg, with a smaller volume fraction of hollow glass spheres) can be introduced and dried. The application of a third and a further layer is of course also possible. As a result, not only can the layer thickness of the molded component be increased in the desired manner, but also special material properties, such as elasticity, can be realized. The further processing includes an attachment to a support, such as a house wall. The attachment can be done by screwing, gluing or due to the low weight of the molded component by a Velcro connection. Such, applied to a support plate can then be provided with a colored paint. A rear ventilation may be provided between the mold component and the carrier. Likewise, the mold component can directly adjoin the surface of the carrier.

The support may be a brick or concrete house wall, but also another support to be insulated. For example, these could be body components of a motor vehicle or of an aircraft. Due to the good insulating properties, such a molded component could also be used in white goods, such as e.g. Refrigerators or freezers are introduced. An insulation can be made for example in ovens or cookware or cooking appliances.

The ability to derive voltages can be e.g. used to provide a Faraday cage or a lightning rod.

If the inorganic materials are chosen such that the mold component or the composite material has heat-dissipating properties, it can be attached to cooling ceilings in the construction sector, to electrical equipment instead of aluminum cooling fins, batteries, tanker trucks, oil coolers of a vehicle, electric motors and the like. Heat can be released in air or water. In such applications, it is expedient for the molded component to have the shape of a cooling body with cooling fins.

Two embodiments, as a mold component can be configured, are shown in Figures 6 and 7. In both figures, the shaped component 10 is approximately plate-shaped. On a first main side 11, which represents a mounting side, the mold component 10 is flat and flat. On a second, opposite main page, the embodiment of FIG. 6 is also flat, while in Fig. 7, a three-dimensional structure is shown. The three-dimensional structure of the embodiment of FIG. 7 may follow constructive or aesthetic considerations. If the (wood) material is processed into a molded component, it has a low weight. The weight is adjustable depending on the components from 140 kg per cubic meter. Due to the materials processed in the (wood) material, this can be provided inexpensively. Since no environmentally harmful substances are used, the (wood) material is non-toxic. In particular, this can be easily recycled.

Without additional material treatments the (wood) material is acid and base resistant. The materials used ensure high stability and no or little deformation. If a higher statics or higher load capacity is required, then the (wood) material can be reinforced with glass fibers and / or metals and / or wood and / or carbon fiber and / or plastics. For all materials mentioned, the (wood) material has a high adhesion. It is also capable of fusion with ceramics, glass materials and other minerals, which also provides high stability and good physical and chemical properties.

By using quartz as an inorganic material and / or hollow glass body and / or volcanic ash as fillers, a high heat insulation can be achieved. This can be easily adjusted to a desired level by the proportion, in particular the hollow glass body.

By adding eg boron nitride as an inorganic material, a heat-dissipating property of the (wood) material can be achieved. The components contained in the (wood) material allow by adding a preservative an increase of the fungicidal and bactericidal Property, so there are no health burdens or impairments.

The fact that the viscosity of the (wood) material is adjustable during manufacture and processing, can be freely formable components allow, so that a broad application of the (wood) material is possible.

The composite material can be permanently connected to metals. The composite material can be permanently combined with organic materials. The composite material can be permanently combined with mineral substances. The composite material can be permanently connected with expanded plastics. Furthermore, further organic or inorganic substances can be introduced into the composite material.

The existing in organic resources openings can be filled with inorganic substances and made to harden. Expanded hydrophilic plastics can be used to produce superficially hydrophobic, 100% recyclable materials.
