摘要:
A paint having high thermal conductivity to be applied to the outer surface of a tire. The paint consists of a rubber compound having a thermal conductivity greater than or equal to 0.2 Wm−1K−1, a viscosity of between 0.5 and 10000 cP and an elasticity modulus less than or equal to 8 MPa.
摘要:
A method for forming a protective coat upon an article includes forming a liquid coating mixture comprising a cross-linking agent and a polymer dissolved within a solvent; applying a first coat of the coating mixture upon the article; evaporating the solvent from the first coat; and cross-linking the article. Also disclosed is a device containing an exterior surface at least partially covered by a coating comprising a cross-linked polymer and a filler material that is selected from the group consisting of a fullerene, a micro-encapsulated material, and a combination of two or more thereof.
摘要:
A type of water-based paint for rubber products principally contains a type of water-based rubber latex containing a type of vulcanizable rubber acting as a dispersoid; an inorganic pigment and/or an organic pigment; and at least one selected from the group consisting of a vulcanizing agent, a vulcanizing accelerator, and a vulcanizing aid. The type of water-based paint contains no organic solvent, has substantially the same workability and coating properties as those of known paints when the type of paint is applied onto a rubber product, also has high adhesion to rubber products, and is ecologically friendly. The type of paint can be prevented from being transferred to a die during vulcanization.
摘要:
A rubber coating for a radiofrequency identification device for a tyre characterized in that it comprises: (a) 100 phr of at least one diene-based elastomer; (b) at least one chemical according to formula 1
wherein the chemical comprises in its structure at least the structure of the 2,2'-methylenediphenol, and wherein the 2,2' - methylenediphenol may be substituted in ortho, para, meta position or any combination thereof with an aliphatic, linear or branched, hydrocarbon chain comprising from 1 to 10 C atoms, or may be polymerized in ortho, para, meta position or any combination thereof with one or more additional alkylphenol units. A radiofrequency identification (RFID) module for a tyre comprising a radiofrequency identification device surrounded by a rubber coating, a tyre or a tyre retread comprising such radiofrequency identification module, and use of a rubber coating for surrounding a radiofrequency identification device.
摘要:
A composite article (20; 120) includes a substrate (22; 122) and a protective coating (32; 132) on at least a portion of the substrate. The protective coating includes reinforcement particles (34) dispersed within an elastomeric matrix (36) that is modified with a silicon-containing modifier selected from polysilsesquioxane, polyhedral oligomeric silicate and polyhedral oligomeric silsesquioxane (POSS).
摘要:
Hot-hardening, reactive compositions based on natural and/or synthetic olefinic, double-bonded elastomers and vulcanizing agents are described that contain at least one fluid polyene with a molecular weight between 400 and 80,000 as well as at least one fluid polybutadiene with a tight molecular weight distribution and a microstructure of 10% to 20% of vinylic 1,2 double bonds, 50% to 60% trans 1,4 double bonds, and 25% to 35% eis 1,4 double bonds. These compositions also contain a vulcanization system made up of sulfur and accelerators and/or quinonoximes, if necessary. Given their tensile shear and peel strengths, these compositions are suited for use as single-component bonding agents, sealants, or coating substances in the construction of automobiles, especially at lower temperatures.
