Definitions
- the invention relates to a binder-free fiber insulation according to claim 9 or 10 and a process for the production of binder-free lignocellulosic fiber insulation materials Claim 1.
- Fiber materials in the form of molded parts or fiber insulation boards are used in a variety of ways in the construction industry but also in the packaging industry. These materials have densities in the range from 50 to 400 kg / m 3 and are generally produced from fiber materials which are produced by thermo-mechanical defibration in the defibrator or refiner from wood chips or other lignocellulosic starting materials, such as rape or cereal straw, hemp, bamboo, bagasse etc. can be won.
- the binder is then added in the form of synthetic resins, for example urea, phenol or melamine formaldehyde resins or polymer diphenylmethane-4,4'-diisocyanate (PMDI) in different proportions.
- synthetic resins for example urea, phenol or melamine formaldehyde resins or polymer diphenylmethane-4,4'-diisocyanate (PMDI) in different proportions.
- PMDI polymer diphenylmethane-4,4'-diisocyanate
- the glued fiber material can now be dried.
- the pneumatic or hydraulic nonwoven is formed, followed by a prepress and hot press stage, which can be carried out continuously or discontinuously.
- insulation boards (approx.
- medium-hard fiberboard 350 to 800 kg / m 3
- MDF medium density fiber boards, 650 to 900 kg / m 3
- HDF high-density fiber boards, 800 to 1200 kg / m 3
- Low-density fibrous materials such as insulation boards
- synthetic or natural binders with proportions in the range from 3 to 20% by weight are used to achieve the desired strengths and swelling values.
- the insulation boards manufactured in the wet process with densities in the range of 150 to 300 kg / m 3 are also made with binders.
- Small amounts of bitumen or paraffin are used for water repellency.
- Disadvantages of the wet process, such as high wastewater pollution, are largely solved today by closed water cycles.
- Another problem with the wet process is the high demand for drying heat to remove the water in the nonwoven fabric.
- the lower the density of insulation boards the easier they can be dried with hot air, for example, and the required energy consumption can be reduced. Since insulation boards are porous materials, drying in hot air can be achieved, but the energy requirement still incurs considerable costs.
- lignin sulfonate is the sulfite waste liquor mixed with phenol oxidizing enzymes from pulp production, with wood particles mixed and processed into chipboard. The enzymes cause an oxidative Polymerization of the phenolic component, which leads to the wood particles sticking together.
- the application for the production of insulation materials is in the Description mentioned, as well as the wet process in one of the subclaims. Both Areas of application are not further specified.
- a transfer of knowledge and process parameters of the material production of MDF in the dry process on the The production of insulating materials in the wet process is not without the state of the art further possible.
- the methods mentioned focus exclusively on an enzymatic activation of the lignin component and its use for increasing the Material strength.
- the incubation times listed in the sources are several Hours to days and are therefore for use in highly productive industrial Process not suitable.
- hydrolases are used individually or in combination with oxidases direct incubation of fibrous material used and processed into fibrous materials.
- oxidases direct incubation of fibrous material used and processed into fibrous materials.
- the Use of cationic charge carriers to precipitate soluble components is here not known.
- WO 98/31762 describes a method in which wood particles are treated with hydrolases be to extract substances by partial hydrolysis and then with the addition of Laccase to produce a binder and this for the bonding of fibers and chips use.
- a purely oxidative activation of the fibrous material is already mentioned Use of a binder provided.
- the U.S.S.R 636311 patent uses hydrolases and oxidases for Plastification of wood chips and other wood particles before defibration described. The goal here is to save energy when grinding.
- the patent DE 43 17 692 A1 describes the production of composite materials renewable raw materials, in which binders based on starch are used. there the pulp is mixed with a liquid additive (water) in one step, then added the binder and formed a fleece after another mixing process. adversely The effect here is that only the fibers are moistened while the binder is dry is added, which can lead to loss of binder, since the accumulation of dry binder particles to the fibers is difficult.
- the object of the invention is to provide a method for producing Very low density fiber materials with improved strength and swelling properties, however without the use of binders.
- the object is achieved by a method with those mentioned in claim 1 Features resolved.
- the subclaims 2 to 8 relate to preferred embodiment variants of the inventive method.
- the task is done by a binder-free Fiber insulation material with the features mentioned in claims 9 or 10 solved.
- the method on which this application is based is based on a direct method Incubation of fibers with mixed enzymes in combination with cationic charge carriers and subsequent processing to plate-like materials. Those with this procedure available materials are described in claims 9 to 12.
- Fibers are used as the starting material for the process from other lignocellulosic substances such as rape straw, flax straw, hemp straw, grain straw, coconut fibers, rice straw, bamboo, bagasse, etc., which are accessible to enzymes.
- the above Raw materials e.g. Wood chips are preferably made in a conventional manner in the defibrator using a thermomechanical process at temperatures from 160 to 180 ° C frayed.
- Other fiber plants such as rapeseed, flax and grain straw can also be used without thermal pretreatment can be purged mechanically in the refiner or extruder.
- the Separation of the fibers can also be done by combining thermal pretreatment, mechanical defibration and chemical digestion according to sulfite, sulfate or organosolv processes respectively.
- An alternative variant to this is the steam explosion process according to Mason. In this process, the raw material after treatment with steam and The pressure is quickly released and the fibers are separated from each other by the burst pressure. to Improving the accessibility of the fiber surface for enzymes can make the fibers before enzymatic treatment can be treated with microwave or ultrasound.
- the fibers are mixed with the enzymes and other substances by dipping and making one Suspended suspension.
- the activation of the fiber in the suspension takes place through enzymatic activation of the three main components cellulose, hemicellulose and lignin with the help of mixed enzymes, consisting of oxidases and hydrolases, in combination with cationic ingredients.
- the incubation times are less than two hours.
- the enzyme mixture is an extract which fermented lignocellulosic particles such as hemp straw chopped wood chips or others is obtained, which were incubated with white rot fungi. Furthermore, submerged manufactured enzymes and industrial enzymes are used. Depending on the type of enzyme Pay attention to optimal temperatures and pH values during fiber incubation.
- the cationic Fabrics are commercially available.
- the fibrous material can be processed from a fiber suspension into fiber insulation panels.
- a nonwoven fabric is formed on a sieve, dewatered and dried.
