Definitions
- the invention relates to a method for producing a shaped body from a hydratable mineral material and a filler or filler mixture and is particularly suitable for producing rigid, flame-retardant or non-flammable plate-shaped or shell-shaped shaped bodies from near-natural raw materials. Furthermore, by means of the above-mentioned process, such shaped articles with good mechanical properties can be produced from secondary raw materials and industrial by-products.
- EP 0713508 B1 proposes to use an adhesive which a thermosetting resin based on legumes and a cellulose material. Since all of these plates have a very high cellulose content, their uses are very limited due to their flammability.
- One way to reduce the flammability of boards made using fibers of vegetable origin is to use mineral binders such as gypsum, cement, anhydrite and the like. This combination reduces the high sensitivity to breakage that results from the mineral binders, since the fibrous materials act as reinforcement. At the same time, the natural fibers improve the thermal insulation of such a panel due to the enclosed air.
- a process for the production of gypsum fiber boards described therein includes the following steps:
- a first mixing step mixture of a predetermined amount of fibers, an extinguishing agent to prevent the adhesion of the fibers to each other, water and gypsum to produce a mixture of wet, loose fibers - in the final mixing step mixing the wet fibers with a predetermined amount of dry, calcined plaster
- the invention described in DE 19817519 AI relates to a process for the production of components, in particular of building boards and of mixtures, organic fibers being used in addition to residues from fossil-fueled power plants.
- the invention is based on the 5 task of producing light and stable components and / or mixtures which can be used in a variety of ways for interior and exterior construction and mainly consist of residual substances and natural materials.
- the three-layer gypsum-based building material board described in DE 4222872 AI which can be used as a wall plate or ceiling board, consists of a lower covering layer, a middle layer and an upper covering layer, which are built up with special gypsum binder / fiber ratios, the middle layer being fiber-rich.
- the building material board points in
- DE 4204840 AI proposes a method for producing gypsum fiber components, in particular building boards, which enables 25 components to be produced with particularly high strength. Dry fibers are mixed with calcium oxide and then moistened. Then this mixture is gypsum and if necessary Water is added and the mixture is then brought into the desired shape.
- the process described in DE 4135144 AI also serves to produce a fiber-reinforced hardened slag / gypsum / cement light product which can be used as a material for the outer and inner walls of building materials and which has good fire and water resistance and good durability.
- the process comprises adding 5 to 140 parts by weight of aggregates with a maximum size of no greater than 2000 ⁇ m to 100 parts by weight of a mixture containing 100 parts by weight of Portland cement, 20 to 350 parts by weight of fine slag powder, 0 to 20 parts by weight of lime and 20 to 100 parts by weight of calcium aluminate and gypsum fine powder as a whole, provided that there is a weight ratio of gypsum fine powder and calcium aluminate in the range from 0.5 to 2.0: 1, further addition of 0.01 to 1.5 parts by weight of a setting regulator to the mixture, mixed water, foams or Foam and reinforcing fibers to the mixture to obtain a slurry, shaping the slurry, removing the resulting molded product and curing the removed product with steam.
- a cured lightweight product can be obtained within a short time by ordinary steam curing, and there is at a high level Free movement in terms of thickness and shape, creating exterior and interior wall materials.
- the invention described in DE 4108581 A1 is directed to the use of textile waste as an additive to a binder for the production of components. It suggests To relieve the landfill for shredded textile waste beyond the use as an additive to mineral and organic binders, to open up new possible uses by adding textile waste material as an additive to the clay binder for the production of clay building elements in the form of strips or strips with a length of 60 to 100 millimeters and a width of 10 to 20 millimeters is used. The textile waste is directed into the loamy mass to form a support structure.
- the use of textile waste material with a defined material shape and specified dimensions as an additive to binders thus also includes the field of cohesive earth materials.
- the fibers are only embedded in the mineral binder.
- the bond between the fiber material and the mineral binder is based only on the irregularities in the surface of the fiber materials and the resulting positive connections.
- only a part of the tensile strength of the fibrous materials can be used to improve the strength of the plates.
- the brittleness of the mineral binder determines the breaking strength of the product and the impact strength of fiberboard cannot be achieved.
- the object of the invention is therefore to propose a method for producing a shaped body from a hydratable mineral material and a filler, which combines the advantages of fiber reinforced panels made of mineral materials with regard to fire resistance and rigidity with the impact strength of hardboard.
- a shaped body is produced from a hydratable mineral material and a filler or filler mixture by mixing the hydratable mineral materials with the filler or filler mixture in a first step.
- a non-water-soluble adhesive is added.
- Such an adhesive is defined as follows according to the definition of the dictionary ABC Chemie-Brockhausverlagtechnik 1964, p. 678. "Adhesive,” is a "non-metallic material for connecting identical or different types of material to one another without changing their structure.
- the adhesive strength is based on the adhesion (adhesion) of the molecules of the adhesive base material to the surface of the material to be bonded and the sufficient mechanical strength (cohesion) the adhesives.
- the adhesives consist of
- Raw materials are natural or synthetic organic polymers with the addition of solvents, plasticizers, fillers, extenders, hardeners or others, the adhesive properties or the setting influencing substances.
- thermoplastic high polymers cellulose nitrate, polyvinyl acetate, polyacrylic and polymefhacrylic acid esters, vinyl chloride mixed polymers and post-chlorinated polyvinyl chloride, polyvinyl ethers and acetates
- synthetic resins Phenol and carbamide formaldehyde resins, epoxy resins, unsaturated polyester resins, polyurethanes, polysulfides, silicones), natural resins (rosin, shellac, copals) as well as waxes and bituminous materials are used.
- the mass is brought into the desired shape, usually a plate shape.
- the solidification of the adhesive is triggered by the solvent of the binder evaporating or the binder being melted or melted on by brief heating. As a result, the materials of the material are glued together at their points of contact.
- the adhesive has solidified in the preformed body, so much water is added to the pre-consolidated mass that the mineral material can set completely. By adding water, the mineral binder hydrates and fills the interstices of the latticework formed from the filling material with a network of connected crystals.
- fillers can include both fibrous or chip-shaped particles made of vegetable material such as sawdust or wood wool, scraping from hemp or flax processing, and fibers of animal origin such as animal hair, bristles, and synthetic fibers, in particular microfibers or ultimately also mineral fibers be used.
- fibrous or chip-shaped particles made of vegetable material such as sawdust or wood wool, scraping from hemp or flax processing, and fibers of animal origin such as animal hair, bristles, and synthetic fibers, in particular microfibers or ultimately also mineral fibers be used.
- mixtures of two or more of the aforementioned substances can also be used for the “construction” of special properties.
- dissolved or meltable natural or synthetic resins and inorganic adhesives with little or no water absorption capacity can also be used as adhesives.
- its solidification can be triggered by heating, by evaporating off an existing solvent and / or by briefly melting the adhesive.
- Mineral materials in the form of processed natural raw materials such as gypsum, anhydrite or lime or industrially produced building materials such as cement or reactive fly ash or mixtures of two or more of the aforementioned materials are suitable for the process.
- the scope of the invention is not exceeded if, when mixing the hydratable mineral material, the Fillers and the adhesive are admixed with other quality-determining substances such as dyes, inhibitors, reaction mediators or metal dusts.
- the molded or layered bodies produced from a surface treatment are finished by grinding, painting or laminating film-like layers.
- the invention In order to be able to make the adhesive bridges between the particles of the filler more stable, the invention ultimately proposes to coat the particles of the filler with a dissolved or melted adhesive before they are added to the mixture.
- Embodiment 1 A panel for use in ecological housing is manufactured as follows. A fiber mixture of hemp shives and the waste from flax spinning is processed in a first step with a Sprayed 10% alcoholic rosin solution. Then 4 times the amount of gypsum obtained from natural anhydrite is mixed in. This mixture is spread into an even layer and pressed into a plate under the action of heat. The plate pretreated in this way is moistened with the aid of a spray device. After the plaster has set and the residual moisture has evaporated, the plate can be used as wall or ceiling cladding.
- Embodiment 2 An outer wall panel for industrial buildings is manufactured as follows.
- a mixture of mineral fibers and sawdust is moistened with polystyrene dissolved in acetone.
- This mixture is mixed with a mixture of cement and sand in equal parts by weight. After the application to a uniform layer, this is passed through several hot rollers and thus compressed under the influence of heat. The resulting strand is passed through a flood of water and cut into plates.
