20150119502 | WOOD PLASTIC COMPOSITES AND MANUFACTURING METHOD THEREOF - Disclosed therein are wood plastic composites and a manufacturing method thereof, which can provide a high discoloration resistance by removing lignin from wood flour which is a main material of the wood plastic composites. The method of manufacturing wood plastic composites includes the steps of: removing lignin contained in wood chips through a cooking process of high temperature and pressure; crushing the wood chip from which lignin was removed in order to produce wood flour; putting and mixing polymer resins and additives into the wood flour so as to manufacture mixture of a gel phase; and extrusion-molding, injection-molding or compression-molding the mixture to manufacture wood plastic composites. The wood plastic composites and the manufacturing method thereof can prevent decoloration and after-yellowing even though the wood plastic composites are exposed to UV or moisture for a long time to thereby enhance long-term weather resistance. | 04-30-2015 |
20150141555 | THERMOPLASTIC STARCH COMPOSITION DERIVES FROM AGRICULTURAL WASTE - A thermoplastic starch composition acquired from compounding a mixture comprises starch-containing agricultural waste in 45 to 70% by weight of total composition that the agricultural waste contains starch content less than 50% in dry weight; thermoplastic synthetic polymer in 25 to 50% by weight of total composition; plasticizer in 0.01 to 10% by weight of total composition; and coupling agent in 1 to 5% by weight of total composition; wherein the compounding is performed at a first temperature which is higher than room temperature. | 05-21-2015 |
20150315354 | FIRE RETARDANT MOLDINGS AND METHOD FOR PRODUCING AND USING SUCH A MOLDING - A fire retardant molding contains a thermoplastic compound and an inorganic flameproof agent that is mixed with the thermoplastic compound and which acts by separating from water, having a proportion in the range of 10 wt % to 90 wt %. The fire retardant molding is produced by mixing the thermoplastic material with an inorganic flame-proofing agent, the flame-proofing agent having a proportion in the range of 20 wt % to 80 wt %, and by outputting the compound obtained by mixing, in particular as a flat product. The fire retardant molding is advantageously used, for example, in or on land-based vehicles, water-based vehicles, aircraft and buildings. | 11-05-2015 |
20160002414 | PROCESS FOR MANUFACTURING PRODUCTS FROM ACETYLATED WOOD FIBRE - A process for forming wood fibre comprising breaking down acetylated wood to produce acetylated wood fibre having a moisture content from about 5% w/w to about 8.5% w/w after it is comminuted to form wood fibre. The process includes a first moisture-introducing step for increasing the moisture content of the acetylated wood elements; and a second moisture-introducing step, separate to the first, for increasing the moisture content of the acetylated wood dements. | 01-07-2016 |
20160024354 | BONDING RESIN FOR WOOD-BASED COMPOSITES PROVIDING LIGHT COLORING, LOW PLATEN STICKING, AND WATER RESISTANCE - Disclosed herein are adhesives, wood-based composites incorporating the adhesives, and methods of forming wood-based composites using the adhesives. Wood-based composites formed using the adhesives demonstrate an optimal combination of characteristics desirable to the wood products industry. Specifically, the wood products formed using the adhesive demonstrate (1) a light appearance when wet; (2) relatively low moisture content after soaking in water; (3) relatively little thickness swelling after soaking in water; and (4) minimal adhesion to metal press platens during press-forming of the wood products. | 01-28-2016 |
20160039981 | LIGNOCELLULOSE COMPOSITE PRODUCTS - Lignocellulose composite products that include a hydrophobizing agent. The lignocellulose composite product can include a plurality of lignocellulose substrates, an at least partially cured binder composition, and a hydrophobizing agent. In one example, the hydrophobizing agent can include about 30 wt % to about 98 wt % of a fatty acid compound, about 0.1 wt % to about 15 wt % of a rosin acid compound, and about 1 wt % to about 40 wt % of an unsaponifiable compound. In another example, the hydrophobizing agent can include a tall oil pitch and a fatty acid composition. | 02-11-2016 |
