Patent number: 8846816Abstract: The invention relates to a process and an apparatus for the preparation of a crosslinkable rubber mixture for vehicle tires, lines, drive belts and other industrial rubber articles, which can be carried out at least semicontinuously. The present invention is based on the discovery that the experiments known from the prior art to carry out the batchwise process usually used at least partly continuously have failed in particular because of the problem that the crosslinking agents have to be mixed rapidly and homogeneously with the base mixture, also referred to as rubber base mixture, without the mixture consisting of the base mixture and the crosslinking agents heating up too strongly. According to the invention, attention was therefore focussed on reliably mixing the base mixture homogeneously with the crosslinking agents and minimizing the mixing time. A first measure for achieving the desired aim consists in first mixing the crosslinking agents with one another before they are mixed with the base mixture.Type: GrantFiled: June 26, 2009Date of Patent: September 30, 2014Assignee: Rhein Chemie Rheinau GmbHInventors: Anno Borkowsky, Andreas Schröder, Hans-Martin Issel, Florian Fischer, Reinhard Uphus

Publication number: 20130273376Abstract: A radiation curing composition suitable for building a three-dimensional object by a solid freeform method is disclosed. The composition includes one or more mono-functional monomers where a respective polymer has a Glass Transition Temperature higher than about 60° C., one or more di-functional oligomers where a respective polymer has a Glass Transition Temperature lower than about 40° C. and a phase separation inducing component. The phase separation may be induced during curing, resulting in a non-clear cured material having an improved impact strength and higher elongation, when compared to similar compositions without a phase separation inducing component.Type: ApplicationFiled: June 13, 2013Publication date: October 17, 2013Inventors: Eduardo Napadensky, David Brusilovsky
