Abstract:
A heat insulation material is provided that is produced by drying a fibrous matrix impregnated with a solution of pseudo-peptides of formula (I), wherein: R is a side-chain of a natural or synthetic amino acid , R1 is either a linear or branched (C1-C3)alkyl group, or a linear or branched (C1-C3)alcoxy group, or an aryl group, or an aryl(C1-C3)alkyl group, or an aryloxy group, or a saturated or unsaturated heterocycle, n=1 or 2, and A is an aromatic or heteroaromatic group with at least one cycle.
Abstract:
The present disclosure describes a treated cellulosic material comprising: a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising: a polymer comprising an olefin-carboxylic acid copolymer; a modifying agent comprising a bivalent, trivalent, or tetravalent metal ion.
Abstract:
The present disclosure describes a treated cellulosic material comprising: a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising: a polymer comprising an olefin-carboxylic acid copolymer; and a modifying agent comprising a polyamine having greater than or equal to 2 amine groups, wherein the modifying agent crosslinks at least a portion of the polymer.
Abstract:
The invention relates to methods to thermally treat wood (e.g., flat-grain timber) to produce wood with enhanced color and/or weathering properties.
Abstract:
The present invention relates to the use of an aqueous preparation for the coating of wood surfaces, characterized in that the aqueous preparation comprises: a hydroxyl-functional polyurethane-polyacrylate dispersion, apolyurethane dispersion, an at least partially hydrophilicized polyisocyanate and ≧0 weight-% to ≦10 weight-% of a matting agent, wherein the combined hydroxyl content of the hydroxyl-functional polyacrylate dispersion and the polyurethane dispersion is ≧1% to ≦12%. The invention further relates to a method of producing a coated wood surface, comprising the step of coating a wood surface with such an aqueous preparation and to a coated wood surface comprising an aqueous preparation whose use has been recited in the context of the use according to the invention.
Abstract:
A method of preserving a cellulosic material are provided. The method includes contacting the cellulosic material with a paraben-containing monomer and polymerizing the paraben-containing monomer. Articles including a cellulosic material and at least one polymer which includes paraben moieties are also provided.
Abstract:
A method for modifying wood includes steps of impregnating the wood followed by curing the wood at temperatures between 70 and 200° C. The impregnation composition includes di-, tri-, and/or polysubstituted furan compounds.
Abstract:
The present invention relates to an impregnating agent for wood against fungi which will break down the cellulose and lignin in the wood. The impregnating agent comprises a mixture of potassium diformate and propionic- and/or acetic- and/or benzoic acid and/or a fixating agent. Said impregnating agent may comprise 0.5–5 weight % of the fixating agent selected among fatty acids, polymers and formates other than potassium diformate.
