20090315209 | Polypropylene/soy-protein compositions of bio-composite materials, bio-composite sheet using that and preparing method thereof - The present invention relates to polypropylene/soybean protein composition for a bio-composite material for an automotive interior or exterior material, a bio-composite sheet prepared by using the composition and its preparation method, and particularly relates to composition for a bio-composite material comprising polypropylene resin, soy protein particles and ZnSO | 12-24-2009 |
20110269872 | PREPARING METHOD OF POLYMER NANO-COMPOSITES - Provided is a method for preparing a polymer nano-composite, more particularly, an economical method for preparing a polymer nano-composite with improved properties via a single process of organic treatment of a layered clay mineral and dispersion in a rubber latex material at a pH where both the rubber latex material and the layered clay mineral are stabilized. The provided method for preparing a polymer nano-composite allows effective dispersion without using an organic modification process for improving dispersibility of the layered clay mineral in resin. Thus prepared polymer nano-composite exhibits superior mechanical property and may be usefully applied for automobile interior and exterior materials. | 11-03-2011 |
20120271001 | COMPOSITION OF POLYKETONE WITH HIGH IMPACT STRENGTH - The present invention provides a polyketone composition having about 40˜90 wt % of polyketone, about 5˜40 wt % of polyamide, and about 5˜20 wt % of modified rubber. The composition of the present invention greatly improves the impact resistance of polyketone, which has increased heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance or the like, and thus may be widely applied in various industrial fields, such as automotive parts including wheel covers, wheel caps, fuel filler necks, fuel tanks, fuel tubes, center fascias, door handles, roof rack covers, gear, junction boxes, connectors, seat backs or the like, electric/electronic parts, and household items, thereby providing durability of the parts and price competition. | 10-25-2012 |
20120288721 | ADHESIVES FOR BONDING POLYURETHANE AND ALUMINUM - The present invention provides an adhesive comprising graphene oxide including at an epoxy group, a hydroxyl group or a carboxylic acid group; and an alkoxysilane compound including an amine group, an epoxy group, a carboxylic acid group, a hydroxyl group, or a thiol group. More specifically the adhesive may be used for bonding a polyurethane elastomer to an aluminum material, in which a silane compound and graphene oxide are applied to improve adhesive strength, compared to adhesives including the silane compound only. In addition, during a separation process for recycling after use, the aluminum material and polyurethane can be easily separated from each other by polyurethane pyrolysis through rapid heating due to microwave absorption properties of graphene oxide. | 11-15-2012 |
20120308726 | METHOD FOR PRODUCING SYNTHETIC LEATHER HAVING AIR PERMEABILITY - Disclosed is a synthetic leather produced by directly coating a water-soluble synthetic resin solution on the surface of a fabric to form a film thereon such that fine gaps formed on the fabric are partially left open to have a certain degree of air permeability. In particular, a brushing process is used for brushing the surface of a fabric using a brushing machine to raise a nap. Next, a hydrolysis-resistant and flame-retardant resin solution is coated on the back of the fabric, which is opposite to the surface on which the nap is raised, to reinforce the back of the fabric. A film forming process then applies a water-soluble polyurethane resin solution to the nap raised on the surface of the fabric to form a film on the surface of the fabric thereby producing a synthetic leather product that has air permeability properties that are superior to genuine leather. | 12-06-2012 |
20130147095 | METHOD AND APPARATUS FOR MANUFACTURING A MAGNETORHEOLOGICAL ELASTOMER - Disclosed is a method and electromagnetic device for manufacturing an anisotropic magneto-rheological elastomer (MRE) with an improved magneto-rheological effect. The electromagnetic device includes upper and lower electromagnets, and a test piece located therebetween. The upper and lower electromagnets are configured to apply a magnetic field of variable strength, which may be controlled by current applied from a power controller, to the test piece in a desired direction or orientation. More specifically, the device is designed in such a manner that carbonyl iron powder (CIP) (magnetic-responsive particles) dispersed in a magneto-rheological elastomer using natural rubber as a matrix can be oriented in the application direction of the magnetic field. A MRE produced by the method and electromagnetic device of the invention prevents formation of bubbles within a test piece, thereby improving the arrangement/orientation of CIP with the matrix. | 06-13-2013 |
20150072123 | COATING MATERIAL FOR ALUMINUM DIE CASTING AND METHOD FOR COATING THE SAME - Disclosed is a coating material for aluminum die casting and a method for coating the same, the coating material including: a CrN adhesion layer formed on a surface of a base material; a TrAlN/CrN support layer formed on a surface of the CrN adhesion layer; and a TiAl(CrSi)VCN functional layer formed on a surface of the TiAlN/CrN support layer. The present coating material solves the hot stamping and sticking problem of a conventional aluminum die casting mold and the like, enhances thermal resistance, and further has enhanced thermal resistance, high-temperature wear resistance, sticking resistance and thermal impact resistance compared to that of a conventional coating material. | 03-12-2015 |
