  • Publication number: 20130000844
    Abstract: The invention relates to polymeric latexes that can be used in adhesive compositions, which provide improved bonding of rubber articles to rubber reinforcing articles. The adhesive composition includes a single or a blend of polymeric latexes comprising a conjugated aliphatic monomer, a vinylaromatic monomer, a vinylpyridine monomer, and a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality. Use of the monomer comprising a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality allows for reduced amounts of the vinylpyridine monomer in the latex, and enhances the bonding properties of the adhesive composition. Use of the adhesive composition provides economic and chemical advantages for the preparation of reinforced rubberized articles.

    Abstract: A method of manufacturing an unvulcanized adhesive waterproof sheet for performing a waterproof construction, and a construction method using the sheet are described. In the manufacturing method, a rubber main material composed of natural rubber and/or synthetic rubber is agitated with vulcanizing compound agent, age resister, adhesion-providing agent, softener, and filler. Vulcanizing agent is then added and agitated thereto in an open roller, thereby producing a raw rubber material, which is rolled and forced out with constant width and thickness. A releasing paper attaches to both surfaces of the waterproof sheet. In the construction method, one surface of the waterproof sheet attaches to a construction surface. The other sheet surface thereof attaches to wet mortar with a constant thickness. The waterproof sheet is turned into vulcanized rubber over time to achieve waterproofness of the construction.

    Abstract: The subject invention pertains to compositions comprising a rubber-like polymer and low boiling point alkanes which can be used to provide a flexible, durable, permanent repair for snags, holes, runs or ladders in hosiery such as pantyhose and nylon stockings. In a preferred embodiment, the rubber-like polymer is a gum-like residue obtained from drying commercial rubber cement adhesive. A composition comprising 2% weight to volume of this residue in an equal volume solvent system of pentane and hexane is applied to the snag and allowed to dry. When the repair is made while the stocking is being worn, a thin, transparent shield can be inserted between the stocking and the skin of the person wearing the stocking. The shield protects the skin from the composition yet does not adhere to the skin or stocking. The shield therefore can be easily removed after the composition is dry or can be left in place between the skin and the hosiery.

    Abstract: A method for bonding heat sinks to packaged electronic components comprises the steps of: (a) exposing to a plasma a surface of a molded polymer formed on a substrate; (b) allowing the plasma to at least partially convert silicon-containing residue on the surface to silica; and (c) bonding an article to the surface by applying an adherent material between the article and the surface. Often, the silicon-containing residue is silicone oil, a mold release compound, which may prevent the formation of a bond when using conventional bonding methods and materials. The silica layer formed on the surface of the molded polymer assists in formation of a proper bond. The plasma may be an oxygen plasma and the adherent material may be selected from either a heat cured silicone-based paste adhesive with a metal oxide filler or a heat cured porous polymer film impregnated with adhesive.

  • Patent number: 5409648
    Abstract: A process is disclosed for producing multiple-layer moulded bodies by injection of a laminate (16) composed of an essentially flexible, foil-like surface material (19) such as leather or textiles, and a foam layer (22) laminated on the back side of the surface material. Before the laminate is introduced in the injection mould, a separating layer (17) is applied on the surface of the foam material. The separating layer is composed of a separating agent that contains a mixture of an aqueous rubber dispersion and a aqueous silicone emulsion.

  • Patent number: 4907564
    Abstract: A plurality of abrasive sleeves (3) surround a wire rope (2) and are spaced at predetermined intervals longitudinally of the wire rope. An elastic material (4) of rubber such as natural rubber is formed between the abrasive sleeves in such a manner as to surround the wire rope. A rubber/metal bonding agent (7) such as chlorinated rubber type bonding agent is used to effect vulcanization bonding between the opposite end surfaces of each abrasive sleeve and the elastic material and between the wire rope and the elastic material. The ends (19) of the wire rope are connected together by a combination of end connecting members (5, 6a) provided with male threads (17, 17a) and fixed to the ends of the wire rope and on internally threaded connecting sleeve (30), whereby a closed loop is formed.

  • Patent number: 4755550
    Abstract: A gelled solid adhesive for coating substrates, typically paper. The adhesive can be made available in stick form and is easily applied in even coats to any surface area of the substrate. The adhesive has sufficient tack enabling the coated substrate to instantly adhere to essentially any free contact surface upon gently pressing the substrate to the free surface. The adhesive coated substrate is easily removable from the contact surface by manually lifting it thereform. The adhesive permits readherence of the adhesive coated substrate to the same or different free contact surfaces. An adhesive coated paper substrate will readhere many times to free paper contact surface. The preferred gelled adhesive product is formed of an aqueous dispersion of components which include a rubber such as natural rubber latex component, a friction reducing agent, a tackifier, an antioxidant, a gelling agent and surfactant.

  • Patent number: RE36855
    Abstract: A solvent-free hot melt process, for preparing a non-thermosettable, pressure-sensitive adhesive from a tackified non-thermoplastic hydrocarbon elastomer. The process employs a continuous compounding device that has a sequence of alternating conveying and processing zones. The processing zones masticate and mix materials in them. Non-thermoplastic elastomers having high molecular weight may be readily compounded into adhesives in the process.
