Definitions
- the invention relates to an OSB board, in particular for the use in the automotive sector, in the furniture sector or indoors from one or more layers of with Binders provided and pressed beach. Further the invention relates to a corresponding component for Use in a vehicle, in a piece of furniture or in an interior. Finally, the invention relates to a corresponding piece of furniture.
- OSB board On an Oriented Beach Board Plate (OSB board) in the Meaning of the invention is a plate the from at least one layer or layer of compressed flat wood shavings, the so-called beaches, consists.
- the Strands of a location are in a preferred direction oriented, for example in the plate longitudinal direction or in plate transverse direction.
- the beaches are in front of the Pressing provided with a binder.
- the exact Production of an OSB board is described in "Pocketbook of Chipboard Technology", 4th revised Edition, 2000, authors Deppe and Ernst.
- a test specimen with a width of 40 mm, a length of 100 mm and any Test specimen thickness over a period of three hours in a 1 liter plastic bottle stored in the Bottle bottom are 50 ml of distilled water.
- the test takes place at a temperature of 60 ° C.
- the while exiting formaldehyde is absorbed by the water, the content of formaldehyde in the water subsequently determines and from this the concentration of formaldehyde indicated and in milligrams per kilogram of dry sample is calculated.
- test chamber method Another method for determining the formaldehyde content is the test chamber method according to the European standard prENV 717-1.
- a test specimen with a specific surface eg a 1 m 2 , total surface area as the sum of top, bottom and edge surface
- a tight chamber with a certain volume eg 1 m 3
- the air is conditioned so that a certain relative humidity (eg 45%) is established in the chamber.
- the chamber itself is tempered to 23 ° C during the test. Now, the air surrounding the test specimen and discharging from the chamber takes formaldehyde out of the specimen.
- the effluent air is then analyzed periodically for its formaldehyde content. From experience, the formaldehyde content of the air decreases with the test time and reaches a constant minimum value, the so-called compensation concentration.
- the test value is the equilibrium concentration of formaldehyde expressed in ppm.
- the perforator method after the European standard EN 120 mentions a procedure for Determination of free formaldehyde content in one Product describes.
- This is in a Extraction apparatus (the so-called perforator) means Toluene on reflux boils off the free formaldehyde the specimen (about 100 g) expelled and in water converted. After an extraction time of about two Hours is the aqueous formaldehyde solution of toluene separated and determines the formaldehyde concentration. Under Consideration of the sample weight is on the free Formaldehyde content of 100 g sample dry mass recalculated. There is an influence of Sample moisture, which is why the standard is a correction of Moisture content via a calculation formula and a Normalization of the final test value to a sample moisture of 6.5%.
- the so-called gas analysis method is carried out after a sample conditioning for 24 hours via CaCl 2 , this corresponds to a relative humidity of 0%, an analysis by means of a gas chromatograph with head-space sensor.
- a comminuted sample is tempered for five hours at a temperature of 120 ° C in the head-space transmitter and the analyzed by gas chromatographs values of the organic constituents in micrograms of carbon per gram sample output.
- the qualitative evaluation must show that no carcinogenic substances are detected according to the list of MAK values.
- the MAK values list is published annually by the Senate Commission at the Deutsche Deutschen Deutschen Deutschenstician for testing harmful ingredients edited. It contains information about the maximum permissible concentration of certain substances on Workplace, the so-called MAK value. It gets away assumed that in compliance with the said Concentrations a health hazard or Inappropriate harassment of employees not to is expected.
- the MAK values list is in section III the classification of certain agents after their proven or suspected carcinogenicity.
- odor test Another test method is the so-called odor test.
- the test vessel is then cooled to 60 ° C.
- At least three test persons assess the subjective sense of smell of the air in the test vessel and evaluate it.
- the notes 1 to 3 mean that the smell is not noticeable until clearly, but not disturbing.
- the notes 4 to 6 mean that the smell is disturbing to unbearable.
- fogging test is a candidate with a diameter of 80 mm in one with a Aluminum foil sealed glass container for 16 hours stored at 100 ° C.
- the exiting, condensable Components deposit on the aluminum foil.
- the resulting mass increase of the film is through Weighing determined and expressed in milligrams.
- formaldehyde-free binder is independent of influencing the emission behavior also for the purpose of achieving special Strength properties of wood moldings known as this is described for example in DE 197 56 154 C1.
- one formaldehyde-free binder is not limited to a specific type of wood provided.
- at Use of a formaldehyde-free binder are according to DE 197 56 154 C1 all conceivable soft and Hardwood species equally suitable.
- the present invention is based on the object an OSB board of the type mentioned in such a way to further educate that emission behavior continues is improved without sacrificing the mechanical and technological Properties of the OSB board in purchase to have to take.
- the term means low emission, that according to the perforator method the content to formaldehyde based on 100 g dry matter less than Is 3.0 mg and in particular less than or equal to 2.5 mg is.
- An OSB board is also low in emissions according to the invention, if after the bottle method the content of formaldehyde based on 1 kg dry matter is less than 3.0 mg and in particular smaller or equal to 1 mg.
- a plate is then Low emissions, if according to the gas analysis method of Formaldehyde content of OSB board based on 1 g Dry matter is less than 90 ⁇ gC and in particular is less than or equal to 60 ⁇ gC.
- an OSB board even when low-emission, if the OSB board after the fogging test a mass condensable constituents less than 4.2 mg and especially less than or equal to 4 mg.
- OSB board For a multi-layer, in particular 3-layer, OSB board It is also advantageous if the strands of each layer from birch, alder, linden, willow and / or poplar wood consist.
- the formaldehyde-free binder Isocyanate-based binder can be used as a binder PMDI.
- the strands of adjacent layers of each consist of different types of wood. So can For example, the middle class excluding beaches made of alder and the two outer layers exclusively Strands of birch included.
- the object of the invention is also achieved by a Component for use in a piece of furniture, in particular a cabinet comprising at least one OSB panel, wherein the plate is formed as described above.
- the problem is also solved by a component for Use in an interior, in particular as Cladding a wall comprising at least one OSB board, the plate being as previously described is trained.
- the object of the invention is also by a piece of furniture, in particular a cabinet, with solved at least one OSB plate, with the plate like previously described.
- Stranded pine trunks became dried strands for the two outer layers and the middle layer produced.
- the strands for the cover layers were with commercial binder based on melamine-urea-phenol-formaldehyde (MUPF) and the Strands for the middle layer with formaldehyde-free PMDI.
- MUPF melamine-urea-phenol-formaldehyde
- the three layers became a 3-layered one OSB board produced, with the beaches in the individual layers were oriented in the same way as the strands of the invention described above Embodiment.
- the mass fractions of topcoat too Middle class were about 1: 1.
- the resulting molded product was in a Contiroll press to a solid endless plate by the action of pressure and temperature pressed, then in formats separated and after cooling in Sternwender in pile stored.
- the test results are shown in Table 1.
- a plate was analogous to Example 1 and the manufactured according to the embodiment. Instead of the wood species spruce was used and the wood species spruce instead of MUPF as a binder was only PMDI used. The test results are in Table 1 cited.
- each layer 2, 3 and 4 consists made of a mixture of 50% birchwood strands and 50 % Alderwood strands.
- the binder used is PMDI, which is formaldehyde-free.
- the OSB board 1 described above has a particular good emission behavior for formaldehyde, organic Constituents, odor and condensable constituents, as a comparison with the previous examples the prior art shows.
- the test results are in Table 1 executed.
- a plate was analogous to embodiment 1 produced. However, instead of the wood species Birch and alder the species of willow, poplar and linden too used in equal parts. The test results are in Table 1.
- a plate was analogous to embodiment 1 produced. As wood species came for the outer ones Cover layers and the middle layer of different woods to Commitment. The weight ratio middle layer: top layer is 1: 1. The ratio of the strands in the cover layers Alder: Birch is 1: 1. The ratio of the beaches in the Middle pine: Spruce is also 1: 1. The Test results are shown in Table 1.
- a plate was analogous to Embodiment 3 produced.
- For the individual layers of the plate were used different types of wood and that is the type of wood Birch for the top layers and for the middle layer Mixture alder: Willow: lime in the ratio 4: 2: 1.
