20080220277 | Lignocelluosic Material Which is Low in Formaldehyde and Method for the Production Thereof - The invention relates to a lignocellulose material comprising a crosslinkable nitrogen compound, technically a formaldehyde condensate, in crosslinked form in a constituent amount (N) of at least 1% by weight, calculated as nitrogen and based on the total weight of the lignocellulose material, in which the ratio (FA/N) of formaldehyde emission (FA), determined by means of the bottle method according to EN 717, part 3, to constituent amount of the nitrogen compound (N) exhibits a value of at most 5.0×10 | 09-11-2008 |
20080223360 | Production of Modified Lignocellulosic Materials - The invention relates to a method for producing modified lignocellulosic materials. Said method consists of the following steps a) the lignocellulosic material is impregnated with an aqueous composition which contains i) at least one cross-linkable nitrogen compound and ii) at least one substance which catalyses the cross-linking, b) the impregnated lignocellulosic materials are treated at higher temperatures in order to remove the water and to cross-link the cross-linkable nitrogen compound. In step b) the impregnated lignocellulosic material is treated with overheated steam. The invention also relates to lignocellulosic materials which are obtained according to said method. | 09-18-2008 |

20080246177 | Production of Moulded Bodies From Lignocellulose-Based Fine Particle Materials - The present invention relates to a process for the production of moldings from finely divided materials based on lignocellulose, and the moldings obtainable thereby. The invention also relates to the use of aqueous compositions which comprise at least one crosslinkable urea compound for the preparation of finely divided materials based on lignocellulose and treated with this composition for the production of moldings. | 10-09-2008 |
20090007818 | Silanization of Wood Turnings and Fibers for Producing Wood-Plastic Composite Materials - The present invention relates to composite materials composed of lignocellulosic fibers, for example wood meal, and thermoplastic polymer. The inventive composite material has improved mechanical properties. According to the invention, it is envisaged that the lignocellulosic fibers, before mixing with the thermoplastic polymer, are treated with an aqueous mixture composed of organopolysiloxanes which contain aminoalkylalkoxysilanes. | 01-08-2009 |
20110143147 | Agent for providing substrates based on cellulose and/or starch with water repellent and simultaneously antifungal, antibacterial insect-repellent and antialgal properties - The invention relates to an agent for providing substrates based on cellulose and/or starch with water-repellent and simultaneously antifungal, antibacterial, insect-repellent and antialgal properties, which contains water and, as active substance, at least one linear, cyclic, branched or crosslinked co-oligomer or mixtures of co-oligomers from the series consisting of the alkyl-/aminoalkyl-/alkoxy- or hydroxy-siloxanes, the use of such agents and a special treatment process using such agents. | 06-16-2011 |
20130298814 | Method for Treating Wood and Wood-Based Materials, and Wood and Wood-Based Materials Obtainable Therewith - The present application relates to a method for treating wood and wood-based materials for enhancing dimensional stability and surface properties and also for preventing cracking and extending durability. More specifically the invention for the treatment of wood and wood-based materials is directed to a method wherein the wood or wood-based material is subjected to a thermal treatment and the wood or wood-based material is at least partly impregnated with a melamine-containing resin. Subsequently the wood or wood-based material thus impregnated is cured with hot steam at not more than 125° C. preferably up to a maximum of 120° C. In a further aspect the present application includes the thermally treated wood or wood-based material, impregnated with melamine resin and cured, that is obtainable from the method of the invention. The present invention lastly provides for the use of melamine-containing resin for impregnating wood and wood-based materials which are or have been thermally modified, for the purpose of increasing the hardness and reducing the dimensional change through thermal modification. The material produced in accordance with the invention can be used as a substitute for teak. | 11-14-2013 |
20140127523 | Functionalized Polyorganosiloxanes Or Silanes For The Treatment Of Lignocellulosic Materials - The present invention relates to functionalized polyorganosiloxanes or silanes for the treatment of lignocellulosic materials. | 05-08-2014 |
