Amino Acid Modified Silsquioxane Adhesion to Enhance Metal Adhesion and Retention of Metal Adhesion to Cured Rubber

摘要

amino alkoxy modified silsesquioxane adhesives to improve metal adhesion and metal retention of cured rubber compound amino alkoxy modified silsesquioxane (amino ams), and / or amino co-ams which also comprise a mercaptosilane or a mercaptosilane blocked, are excellent adhesives for coating coated or uncoated metal wire for adhering the wire to a rubber filler. amino ams and / or amino / mercaptan co-ams adhesives can be used with all types of rubber and there is no requirement for the use of special rubber vulcanization adhesive additives such as but not limited to cobalt , resins and high sulfur levels. in particular, the use of amino ams and / or amino / mercaptan co-ams compounds as adhesives for rubber bonding wire also improves the performance of the adhesion of the ribs to obtain sufficient binding that is resistant to degradation over time. , especially resistance to thermal aging and / or thermo-oxidant, in particular corrosion in the presence of water. Vulcanized rubber compositions containing an amino ams and / or amino / mercaptan co-ams compound also improved adhesion for incorporation into the uncoated steel after moisture aging, compared to vulcanized rubber compositions which did not contain amino alkoxy modified silsesquioxane.
