Adding Fibrous Material To A Latex, Dispersion, Or Emulsion Containing A Solid Polymer Patents (Class 521/68)
  • Patent number: 10703909
    Abstract: Fossil-fuel and rubber-derived waste stream conversion to composite lumber substitutes or barrier members; the composites having material properties and uses of greater value than the solid waste stream components separately or together. Preferred combinations including waste materials derived from waste carpet, waste tires, and waste bituminous roofing shingles, all enormous problems for landfill disposal. In a range of formulation ratios, when combined with a binder, new and marketable products are made from solid waste. Improved resistance to rot, to water, and to weathering is exhibited in synergy with improved compressive and flexural strength, enabling production of a wide variety of useful and environmentally-friendly structural products, for example. Product weight and strength can be engineered to suit and may be structural members for architectural, engineering or agricultural use.

  • Patent number: 4463039
    Abstract: A composition comprising mineral wool and polyolefin fibers is adaptable for spraying onto a ceiling or wall or the like to form a textured acoustical coating.The fibers are mixed with a binder, water and foaming agent to form a foamy composition. The composition is confined under pressure and released through a nozzle to form a steam. Compressed gas is introduced into the stream to atomize the composition.

  • Patent number: 4447560
    Abstract: Disclosed is a method of producing a low density fibrous composition that is suitable for use as an insulation material. The method comprises first forming an aqueous mixture comprising fibers and a synthetic rubber binder for the fibers and a foamed detergent to a consistency ranging from about 4 to about 15 weight percent solids. The mixture is then foamed to homogeneously suspend all of its components therein and then dried to form the low density fibrous composition.

  • Patent number: 4443562
    Abstract: A process for making a lightweight structural member or insulating coating uses an initial mixture of hydrated lime, a dispersible additive, rock wool and, optionally an aggregate. This mixture has added to it water, and the water/solids mixture is agitated at high speed to produce a castable slurry having 60-80 volume percent air bubbles. The mixing is desirably conducted in a mixer having a cylindrical chamber and using paddles which rotate about their own axis and wherein there is movement of the chamber wall relative thereto, and the blades desirably scrape the chamber wall during such relative rotation.

  • Patent number: 4337594
    Abstract: In the cultivation of mushrooms from an underlying bed containing mushroom spores, novel compositions and processes are provided for a casing layer which is placed over the compost layer containing spawning mycelium. A hydrophilic, thermosetting prepolymer resin is mixed in with a casing substrate, preferably Canadian peat, other optional additives and sufficient amount of water to form a slurry, and the mixture is allowed to cure to a spongy block. The cured material is then pulverized and deposited as a casing layer over the compost layer. Because of the high water retention qualities of this material, watering the mushroom beds is reduced by a factor of three or more, thereby reducing operation and production costs, as also the incidence and severity of disease and displeasing blemishes.

  • Patent number: 4277568
    Abstract: A sealant for the remedial sealing of self-sealing coke oven doors, or ordinary coke oven doors sealed with a conventional lute, or for sealing spigot joints in off-gas pipe lines in coke oven installations comprises a mixture of from 25 to 45% of a latex, (preferably a PVA-based latex) from 10 to 25% water, from 25 to 45% of a particulate filler (preferably a talc) and from 5 to 15% of an inorganic fiber (preferably an asbestos fiber). At least 40% of the fiber should pass through a British standard 100-mesh sieve.The sealant may vary from a flowable to a putty or paste-like consistency and may be applied by spraying or trowelling as appropriate. If the inorganic fiber is not an asbestos the sealant may also include a proportion of a water soluble thickener to enhance the compatibility of the mixture.

  • Patent number: RE39339
    Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a fiber-reinforced, starch-bound cellular matrix. Suitable mixtures used to form the articles are prepared by first preparing a viscous preblended mixture comprising water, a gelatinized starch-based binder, and fibers having an average length greater than about 2 mm. The highly viscous preblended mixture effectively transfers the shearing forces of the mixer to the fibers. The final moldable mixture is then prepared by mixing into the preblended mixture the remaining starch-based binder, water, and other desired admixtures, e.g., mold-releasing agents, inorganic filler rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria.
