  • Patent number: 8962129
    Abstract: A rubber-reinforcing cord (12) as a rubber-reinforcing member of the present invention is a rubber-reinforcing member for reinforcing a rubber product (such as a toothed belt (1)). The rubber-reinforcing cord (12) includes a reinforcing fiber or a reinforcing fiber sheet, and a first coating film provided on a surface of the reinforcing fiber or a surface of the reinforcing fiber sheet. The first coating film is formed by applying a first treatment agent containing polyvinyl alcohol and a crosslinking agent to the reinforcing fiber or the reinforcing fiber sheet and drying the first treatment agent. In the reinforcing member of the present invention, a second coating film as a primary coating film may be provided on the surface of the reinforcing fiber or the surface of the reinforcing fiber sheet. The second coating film can be produced using a second treatment agent containing a rubber latex, for example.

    Abstract: A fiber is provided that has been thermally drawn from a fiber preform, having a longitudinal-axis length and including at least one core that has a longitudinal core axis parallel to the longitudinal axis and internally disposed to at least one outer fiber cladding material layer along the fiber length. The fiber is fed through a localized heating site having a heating site temperature, T, that is above a melting temperature of the fiber core, with a feed speed, ?f, that melts a portion of the fiber core at the heating site, causing molten droplets to pinch off of fiber core material, one droplet at a time, with a time period of molten droplet formation set by the fiber feed speed, ?f. The fiber is fed through the localized heating site to move the molten droplets out of the heating site and solidify the molten droplets into solid in-fiber particles.

A particle is bonded covalently to the fiber through an intermediate coupling agent. Multiple particles can be covalently bonded to the fiber, the multiple particles can be bonded uniformly or asymmetrically around the fiber diameter. A process for modifying a fiber includes creating surface activated reactive moieties thereon. The activated fiber is then exposed to a liquid solution containing a coupling agent to form a covalent bond. The coupling agent is also reacted with a particle in a liquid solution to form a covalent bond between the coupling agent and the particle. The coupling agent is covalently bonded to either a particle and then bonded to the fiber, or vice versa.

    Abstract: A reinforcement means for moulded and extruded articles such as tires has a metal structure with a layer of silica gel bonded thereto. The silica gel bonds the reinforcement means to the rubber compound during the moulding/vulcanisation of the rubber compound without the need for a slow curing stage. The silica gel may be applied to the metal structure by a sol-gel process with the gel formed by drying the sol at a temperature up to 150° C. The reinforcement means is preferably a cable formed from steel wires coated with the silica gel. To further improve bonding of the silica gel to the rubber compound, an organosilane bonding agent may be included in the rubber compound or the reinforcing means provided with a second layer comprising an organosilane as a bonding agent. The reinforcement means are particularly useful for strengthening and providing geometric stability to tires.

  • Patent number: 6641749
    Abstract: A method for manufacturing a tire retardant cellulose insulation with reduced density and reduced settling. The method consists of adding a material, the fibers of which have a positive electrostatic charge, onto a shredded newspaper base either before or after the addition of a pre-coat, consisting of a mixture of limestone and an antistat. A fire retardant agent is then added and the materials are ground in a finish mill. The newspaper fibers become positioned at an angle to the paper pieces, increasing the distance between the paper pieces, thereby lowering the density of the cellulose. Fibers such as ground cardboard, wood mulch, sawdust, and fiberglass fibers are examples of materials with electrostatically positively charged fibers.

  • Patent number: 6641750
    Abstract: An improved fire retardant cellulose insulation with reduced density and reduced settling. A method consists of adding a material, the fibers of which have a positive electrostatic charge, is added onto a shredded newspaper base either before or after the addition of a pre-coat, consisting of a mixture of an inorganic, non-hygroscopic powder and an antistat. A fire retardant agent is then added and the materials are ground in a finish mill. The newspaper fibers become positioned at an angle to the paper pieces, increasing the distance between the paper pieces, thereby lowering the density of the cellulose. Increasing the amount of antistat will decrease settling at the expense of increasing density. Adding water to the insulation system will neutralize static electricity and minimize settling. Fibers such as ground cardboard, wood mulch, sawdust, and fiberglass fibers are examples of materials with electrostatically positively charged fibers.

  • Patent number: 6468654
    Abstract: A treating agent comprises a nitrile group-containing highly saturated polymer rubber latex (A) having an iodine value of 120 or less, a rubber latex (B) other than the highly saturated polymer rubber latex, and a water-soluble resorcinol/formaldehyde condensate in amounts of 15 to 80%, 5 to 70% and 2 to 15%, all by weight in terms of solids, respectively. A rubber-reinforcing fiber product is coated with the treating agent. A rubber article such as a toothed belt, a tire and the like is made using this rubber-reinforcing fiber product. The glass fiber product coated with the treating agent may be further coated with a halogen-containing polymer-based adhesive as a secondary treating agent. Thus, the treating agent exhibits a large bonding force between the reinforcing fiber product and a matrix. Even if the rubber article is repeatedly subjected to a flexing stress, the strength thereof cannot be reduced. A peel-off cannot occurs between the reinforcing fiber product and the rubber matrix.

  • Patent number: 5958533
    Abstract: The problems caused by chemical and thermal shrinkage of hard roll covers, are reduced by the inclusion of one or more intermediate compressive layers between the metal roll substrate and the outer cover, or cover. A compressive layer has the properties of being rigid enough to allow the cover to be applied to the roll, and compressible enough to deform and absorb the stresses which occur as the cover is shrinking during processing.In one embodiment, the intermediate compressive layer comprises a three dimensional fabric that is filled preferably with a thermoset resin system which cures at lower temperature than cover. In a second embodiment, the precise amount of shrinkage in the roll is predetermined to a high enough degree of accuracy so that a depth for the fabric layer can be used to compensate for the amount of shrinkage, thereby eliminating the need for filling. In a third embodiment, the compressive layer is comprised of a meltable material wherein said material melts at cure temperatures.
