20100007047 | Recycled thermoplastic composition comprising waste thermoset material and methods of making - The present invention provides methods for making shapeable composite materials or shaped articles from recycled materials comprising forming a crumb slurry by, in any order, increasing the particle size of a composition comprising white water waste from one or more emulsion or dispersion polymer and combining the white water waste polymer with one or more waste thermoset material, preferably, ground tire rubber (GTR), and, then processing the combined material wet or dry as a thermoplastic to form the composite material or article. Additionally, shaped articles and composite materials can be made from substantially all recycled waste materials, such as white water waste from acrylic or vinyl polymer emulsions and waste rubber vulcanizates. The composite materials can consist essentially of reshapeable materials, i.e. without crosslinking agents, thermosettable compositions or compatibilizers to provide reshapeable or recyclable articles. | 01-14-2010 |
20100009152 | Methods for making composites having thermoplastic properties from recycled crosslinked polymer - The present invention provides methods of making shapeable composites in the form of finely divided materials or articles and the materials and articles produced by the methods, the methods comprising forming mixtures by (i) treating an aqueous thermoplastic acrylic or vinyl polymer to increase the particle size thereof to a weight average particle size of 1 μm or more, and, optionally, dewatering to form a crumb mixture; and (ii) combining a thermoplastic acrylic or vinyl polymer with one or more waste rubber vulcanizate having a sieve particle size ranging from 10 to 600 μm in the amount of from 15 to 95 wt. %, based on the total weight of polymer and rubber to form a crumb slurry, such that (ii) can take place before, during, after (i) but before any dewatering, or after any dewatering; and (iii) thermoplastic processing the mixture. Thermoplastic processing can directly form articles, like sheets or films. The shapeable composites have excellent adhesion to other materials. In one embodiment, the sheets and films can be formed into laminates. | 01-14-2010 |
20100016456 | Process for making polymer composites having thermoplastic properties - The present invention provides methods of making composite materials comprising combining particles of crosslinked rubber with coagulated aqueous polymer dispersions to form a mixture in aqueous dispersion, and subjecting the aqueous dispersion mixture to solid state shear pulverization to form materials that can be processed as thermoplastics at crosslinked rubber concentrations of from 10 to as high as 95 wt. %, based on the total solids of the material. The method may further comprise kneading the pulverized product to form useful articles, such as roofing membranes and shoe soles. | 01-21-2010 |
20100112344 | Blocking and stain resistant surface treated articles and methods for making - The present invention provides surface treated articles comprising a recoatable surface treatment of an acrylic or vinyl polymer that does not change the appearance of the treated surface, and which imparts blocking resistance and/or stain and dirt pickup resistance to the treated surface. The one or more acrylic or vinyl polymer has a number average molecular weight of from 1,000 to 100,000, a glass transition temperature of −10° C. or higher, preferably, 30° C. or higher, and comprises the polymerization product of one or more non-ionic monomer, such as methyl methacrylate, with up to 47 wt. % of an ethylenically unsaturated acid monomer and, preferably, is non-migrating under use conditions. When dry, the surface treatments may form a layer of domains of polymer distributed all over the treated surface, rather than a film. Treated articles include coating or painted articles and elastomer films exhibiting blocking and stain resistance, and uncoated wood, glass, metal or plastic articles and laminates, such as countertops, exhibiting stain and dirt pickup resistance. | 05-06-2010 |
