Title: Composition for promoting adhesion between rubber and textiles
Inventor: MICHIELS DANY FELIX MARIA
IPC: C09J5/00
Filed: 1999-02-09
Granted: 2008-10-07
Abstract: A composition for the promotion of adhesion between a rubber formulation and a textile substrate is provided. The inventive composition comprises either a mixture of specific amine functional silanes and organo-functional silanes having reactive groups or groups with an affinity for rubber. The inventive method entails the use of the inventive composition or a silane compound having both an amine moiety and a reactive group having an affinity for rubber formulations, particularly an unsaturated carbon-carbon bond. The composition may be utilized to adhere any standard reinforcement-type textile, such as polyester or polyamide, to a standard rubber composition, such as SBR, NBR, or EPDM. A method for adhering textiles to rubber formulations is also provided involving a pre-dip, -spray, -coat, and the like, of the inventive composition on a reinforcement-type textile surface followed by the contacting of the rubber formulation. Optionally, and preferably, the process involves the extra utilization of resorcinol- formaldehyde latex as an effective bonding agent to improve the adhesion between the two layers. The resulting textile-reinforced rubber product may be utilized as an automobile fan or timing belt, an automobile tire component, and any other rubber article which requires long- lasting, durable textile reinforcement.

Abstract: A cathode plate particularly adapted for zinc and copper electro-winning and refining includes a panel of aluminum having a top and two opposed side edges, a sloped plastic shield along the top and plastic ribbons along the side. A head bar with two hooks is welded on the top of the plate. The top plastic molding and the side edge ribbons are manufactured simultaneously by a specially devised injection machine. When the cathode plates are immersed into the electrolyte, the top plastic shield keeps the zinc deposit level uniform and prevents the top portion and the liquid contact area of cathode plates from corrosion by acid mist generated during electrochemical reactions. The sloped lower part of top plastic shield facilitates inserting a stripping knife between the zinc deposit and the cathode plate.
