Publication number: 20200368978Abstract: Described herein is a process for producing polyurethane sandwich moldings including at least one core layer and at least one reinforcing fiber layer, where (i) at least one reinforcing fiber layer is applied onto a core layer and a moisture-curing polyurethane adhesive is applied to a reinforcing fiber layer, (ii) the part from (i) is placed into a mold and pressed in the mold and the moisture-curing polyurethane adhesive is cured, and (iii) the molding from (ii) is removed from the mold and optionally subjected to further operations, where the moisture-curing polyurethane adhesive is applied before or after application of the reinforcing fiber layer onto the at least one core layer and for the curing the moisture-curing polyurethane adhesive is brought into contact with water or with a solution comprising water. Also described herein are a polyurethane sandwich molding obtainable by such a process and a method of using a polyurethane sandwich molding in vehicles.Type: ApplicationFiled: December 11, 2018Publication date: November 26, 2020Inventors: Georg Partusch, Juergen Schneider, Gerd Westermann, Klaus Schmutzer

Patent number: 10196493Abstract: The present invention relates to a process for the production of polyurethanes where (a) polyisocyanate, (b) polymeric compounds having groups reactive toward isocyanates, (c) catalysts, (d) a CH-acidic compound of the general formula R1—CH2—R2, where R1 and R2 independently of one another are an electron-withdrawing moiety of the general formula —C(O)—R3 or —CN, where the moiety R3 is selected from the group consisting of —NH2, —NH—R4—NR5R6, OR7 or R8, where R4, R5, R6, R7, and R8 are independently selected from the group consisting of aliphatic, araliphatic or aromatic hydrocarbons, which may have substitution, and optionally (e) blowing agent, (f) chain extender and/or crosslinking agent, and (g) auxiliaries and/or additives are mixed to give a reaction mixture, and the reaction mixture is allowed to complete a reaction to give the polyurethane. The present invention further relates to polyurethanes produced by this process and to the use of these polyurethanes in the interior of means of transport.Type: GrantFiled: November 27, 2014Date of Patent: February 5, 2019Assignee: BASF SEInventors: Iran Otero Martinez, Georg Partusch, Christian Hagen

Publication number: 20160123225Abstract: The present invention relates to a thermally insulated internal combustion engine where a polyurethane foam entirely or to some extent surrounds the external surface of one or more parts of the internal combustion engine. The present invention further relates to a process for the production of a thermally insulated internal combustion engine by taking an engine part, using a mold to surround the part that is to be surrounded with foam within the internal combustion engine part, thus producing a cavity between engine part and mold, charging a polyurethane reaction mixture into the cavity, allowing the polyurethane reaction mixture to complete its reaction to give a polyurethane foam, and removing the mold.Type: ApplicationFiled: May 23, 2014Publication date: May 5, 2016Applicant: BASF SEInventors: Han Sung PAIK, Udo HADICK, Thomas BARTZ, Georg PARTUSCH

Patent number: 8299171Abstract: The present invention relates to a spray-polyurethane system which comprises a polyol component (A) and an isocyanate component (B), where the polyol component (A) comprises a1) at least one compound reactive with isocyanate, a2) at least one reactive chain extender having at least two groups reactive toward isocyanates, where at least one group reactive toward isocyanates is a free, primary NH2 group, and also a3) at least one metal catalyst, and a4) if appropriate, further additives, where the spray-polyurethane system comprises no amine catalyst. The present invention moreover relates to a process for production of a backing layer composed of polyurethane for moldings and to the use of this backing layer for production of automobile parts. Inventive backing layers have good mechanical properties, and low emissions, and their demolding time is small when compared with the open assembly time.Type: GrantFiled: July 18, 2007Date of Patent: October 30, 2012Assignee: BASF AktiengesellschaftInventors: Cord Schmalkuche, Udo Hadick, Holger Leifheit, Georg Partusch, Franz Xaver Redl

Patent number: 5393111Abstract: A bumper assembly for a motor vehicle is disclosed which can be fastened via at least one supporting element and, by means of a screw connection, on a part fixed to the vehicle. A foam energy absorber is provided on which the at least one supporting element is mounted. The supporting element, which reaches virtually over the entire height of the energy absorber, is designed approximately in the form of an umbrella. The umbrella edge, which terminates flatly, bears on the part fixed to the vehicle and, at a distance from the umbrella edge on the underside of the supporting element, supporting webs are provided which are likewise supported on the part fixed to the vehicle.Type: GrantFiled: November 8, 1993Date of Patent: February 28, 1995Assignee: Mercedes-Benz AGInventors: Konrad Eipper, Gerd Gutenberger, deceased, Thomas Gutenberger, heir, Georg Partusch
