摘要:
The present invention relates to a pulverulent adhesive for textile reinforcing inserts, which is dispersible in water, for the production of reinforced rubber products. The adhesive thereby comprises an at least partially capped, low-molecular isocyanate, a wetting agent, a binder and also possibly further additives.

A method for bonding a material to a first substrate surface that includes providing a catalyst at the first substrate surface and then contacting that surface with a material that undergoes a metathesis reaction to bond the material to the first substrate surface. There are two embodiments of this method—a coating process and an adhesive process. In the coating embodiment, the metathesizable material is contacted with the catalyst on the substrate surface so that it undergoes metathesis polymerization to form the coating. The adhesive process includes (a) providing a catalyst at the first substrate surface, (b) providing a metathesizable material between the first substrate surface and the second substrate surface, and (c) contacting the catalyst on the first substrate surface with the metathesizable material so that the metathesizable material undergoes a metathesis reaction and bonds the first substrate surface to the second substrate surface.
摘要:
A transmission belt is made of a cord, a rubber or thermoplastic matrix, and an adhesion material which is able to adhere the cord to the rubber or thermoplastic matrix. The cord is made of at least two yarns, such that a first yarn has a melting or decomposition point T1 and a second yarn has a melting point T2, wherein T1>T2. A ratio of a linear density of the first yarn to a linear density of the second yarn is between 1,000:1 and 1:1, wherein the second yarn is fused to the first yarn. A method of making such cords includes intertwining the first and the second yarn and then heating to a temperature between T1 and T2, with the heating step being integrated with or followed by a step wherein the cord is subjected to a dipping treatment with a rubber adhesion material.

A method of bonding an ethylene.&agr;-olefin rubber composition to a fiber cord. The method includes the steps of: treating a fiber cord with a first treating solution that is at least one of an isocyanate compound and an epoxy compound; after treating the fiber cord with the first treating solution, treating the fiber cord with a second treating solution including resorcinol-formalin-rubber latex; after treating the fiber cord with the second treating solution, treating the fiber cord with a third treating solution including a halogenated polymer and a vulcanizing agent; and after treating the fiber cord with the third treating solution, vulcanization-bonding an unvulcanized ethylene.&agr;-olefin rubber composition to the fiber cord.
摘要:
This invention relates to a method of promoting the adhesion of textiles to rubber compounds through a vinyl compound plasma pre-treatment procedure and a subsequent application of resorcinol-formaldehyde latex (RFL) to the textile surface. The inventive method encompasses a process through which free radicals of compounds comprising strong carbon-carbon bonds form a film over textile films and then covalently bonded to the resin component of the RFL. Such a method thus produces an extremely strong and versatile adhesive that facilitates adhesion between rubber compounds and heretofore unusable or difficult-to-use textiles. The resultant textile/rubber composites are utilized as reinforcements within such materials as automobile tires, fan belts, conveyor belts, and the like. Such materials and composites are also contemplated within this invention.

摘要:
The anchoring of the carcass reinforcing elements 1 is assured by circumferential cables 2, with the interposition of a connecting rubber composition 3. The circumferential cable 2 is arranged in several turns forming one or more helices. These circumferential cables have an operational elongation rate A.sub.f =A.sub.e +A.sub.p of more than 4%. This operational elongation rate does not include the specific elongation A.sub.s of the "cable" effect. The maximum stress R.sub.m of the cable 2 is preferably more than 2000 MPa. The cables have undergone a heat treatment which has, in combination, the features of being a recovery annealing treatment and which is carried out directly on cable comprising wires previously separately covered by an adherent coating.
摘要:
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. Moreover, the rubber article has sufficient heat and water resistances.
