Bonding promoter used for rubber/metal composite sealing plate, its preparation method and purpose thereof

Abstract

The invention relates to a bonding promoter used for a rubber / metal composite sealing plate, its preparation method and a purpose, which is characterized in that the bonding promoter used for the rubber / metal composite sealing plate is prepared by nickel sulfate, rose vitriol, sodium carbonate, glacial acetic acid, isocaprylic acid and tri-n-butyl borate. The preparation method comprises the following steps: injecting a sodium carbonate solution in a nickel sulfate / cobalt solution for reacting to obtain nickelous carbonate / cobalt; mixing the prepared cobaltous carbonate and nickelous carbonate to prepare mixed carboxylic acid cobalt nickel; and performing a boron acylation reaction to obtain nickel borate acylate and cobalt borate acylate; wherein the purpose of the invention is used for bonding the metal rubber composite plate. The bonding promoter contains cobalt and nickel, a molecular structure is similar with that of the nickel borate acylate and that of the cobalt borate acylate, the corrosion resistant and aging resistant performances are analogous with the current cobalt borate acylate, so that the bonding strength between the rubber and the metal is increased, production cost is reduced, and the abundant nickel resource in our country can be fully used.

Description

technical field [0001] The present invention relates to a kind of chemical preparation and its preparation method and application, particularly relate to a kind of rubber / metal composite sealing plate containing nickel and cobalt metal and its preparation method and application. Bonding to metal-rubber composite panels. Background technique [0002] The rubber / metal composite sealing plate not only has the high compression resilience and compactness of rubber materials, but also has the stability and high strength of metal materials, so it is widely used in sealing, sound insulation, anti-vibration and other industrial industries. Due to the many performance advantages of rubber / metal composite sealing plates, many famous universities and manufacturers at home and abroad are researching and producing different rubber / metal composite sealing plates. The current research shows that there are obvious differences in the surface tension and reaction points between rubber and met...
