Problems solved by technology

[0003] At the higher temperatures customary in injection molding processes today, aromatic polynitroso compounds tend to sublimate, causing the injected rubber compound to react with the aromatic polynitroso compounds, and before the material fills the injection mold, it is already destroyed. vulcanized and reacts with the adhesive on the metal surface, this pre-vulcanized rubber will not mix with the rest of the rubber in the mold, resulting in the formation of a weak interfacial layer and premature failure of the vulcanized product

Embodiment Construction

[0034] The foregoing description and the following examples are intended to disclose and illustrate the present invention, and the specific amounts and combinations of the ingredients described herein are not intended to limit the scope of the present invention defined by the claims.

[0035] The p-benzoquinonedioxime-bis(1,3,5-tri-tert-butyl-4-oxocyclohexyl-2,5-dienyl)-ether of the present invention was prepared as follows:

[0036]

[0037] p-Benzoquinonedioxime-bis(1,3,5-tri-tert-butyl-4-oxocyclohexyl-2,5-dienyl)-ether

[0038] 90 g of 2,4,6-tri-tert-butyl-phenoxy radical was added to the benzene solution under the condition of flowing sufficient argon gas, and then 52 g of p-dinitrosobenzene was added. The reaction temperature was kept at about 20 °C until the color of the solution changed from light green to yellow. Then the unreacted p-dinitrosobenzene and benzene were distilled off at 30°C, and the residue was recrystallized with ethanol. 75 g of p-benzoquinonediox...

Abstract

The invention discloses a vulcanized rubber or thermoplastic rubber and metal adhesive which comprises parabenzoquinone dioxime-bis(1,3,5-tritertiary butyl-4-oxocyclohexyl-2,5-dialkylene)-ether, parabenzoquinone dioxime-bis(1,3,5-tritertiary butyl-4-oxocyclohexyl-2,5-dialkylene)-ether halogenated rubber, a metal oxide such as zinc oxide or magnesium oxide, inert color filler carbon black or titanium dioxide, a solvent such as arene, chlorinated solvent or ketone solvent, a polymaleimide compound such as N,N'-m-phenylene dimaleimide or diphenylmethane dimaleimide, and a vulcanizing agent such as sulfur, selenium or tellurium. The adhesive is mainly characterized in that the adhesive does not contain aromatic multi-nitro compounds and has the performance of preheating resistance or meets the requirements of an injection moulding process.

Description

technical field [0001] The present invention relates to a vulcanized rubber or thermoplastic rubber and metal adhesive for bonding vulcanized rubber or thermoplastic rubber to metal. technical background [0002] A number of adhesives have been developed to provide bonding of vulcanized rubber or thermoplastic rubber to metal. For example, CN200580019624.7 of LORD Company discloses a rubber-metal adhesive whose solid is dispersed in a volatile liquid carrier, the adhesive contains dispersed solid particles, and the solid particles contain nitroso compounds, halogenated polyolefins, Acid neutralizer and 5-35 wt% inert incompressible spherical particles. CN93114420.5 discloses an adhesive containing halogen-containing polyolefin, aromatic nitroso compound, polymaleimide compound and metal oxide. Among them, however, aromatic polynitroso compounds are particularly preferred. [0003] At the higher temperatures customary in injection molding processes today, aromatic polynitr...
