Problems solved by technology

[0003] At the higher temperatures commonly used 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

[0042] 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.

[0043] The crosslinker N,N'-dinitroso-p-phenylene dihydroxy disodium of the present invention was prepared as follows:

[0044]

[0045] N,N'-Dinitroso-p-phenylene dihydroxy disodium

[0046] 136 g of p-benzoquinonedioxime were added to 3,000 ml of methanol with stirring to form a suspension. After adding 108.04g of sodium methoxide, slowly feed 60.02g of nitric oxide gas so that the temperature of the reaction mixture does not exceed 27°C. After completion of the nitric oxide feed, the reaction mixture was stirred for an additional 15 minutes. Use sodium hydroxide solution, plus air, to absorb excess nitric oxide gas. Centrifuge the precipitate, suspend it in neutral water, filter and...

Abstract

The invention discloses a heat vulcanized adhesive for adhering a vulcanized rubber or a thermoplastic rubber with a hard panel. The heat vulcanized adhesive comprises a crosslinking agent N,N'-dinitroso-p-phenylene dihydroxy disodium, halogenated rubber, metal oxide such as zinc oxide or magnesium oxide, inertia stuffing such as carbon black or titanium dioxide, a solvent such as aromatic hydrocarbon, chloride solvent or ketone solvent, a polybismaleimide compound such as N,N'-m-phenylene bismaleimide or diphenylmethane bismaleimide, and a vulcanizing agent such as sulphur, selenium or tellurium. The heat vulcanized adhesive has the characteristics that the heat vulcanized adhesive does not comprise aromatic polynitroso compound, adduct of perhalogenated cyclic conjugated diene / olefinic unsaturated dienophile, and copolymer formed by halogenated butadiene monomer / alpha-halogen substituted monomeric compound, and also does not comprise any one of alkoxy silane / polymer of nitrosobenzene or nitrosobenzene precursor combination; meanwhile, the heat vulcanized adhesive has pre-heating-resistance or is suitable for the requirement of injection molding process, and has the slat mist resistance and boiled water resistance.

Description

technical field [0001] The present invention relates to a thermally vulcanized adhesive for bonding vulcanized rubber or thermoplastic rubber to hard plates, and the heat vulcanized adhesive is used for bonding vulcanized rubber or thermoplastic rubber to hard plates. technical background [0002] A number of heat vulcanizing adhesives have been developed to provide bonding of vulcanized or thermoplastic rubber to rigid sheet materials. 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 a thermal vulcanization adhesive containing halogen-containing polyolefin, aromatic nitroso compound, polymaleimide compound and metal oxide. Among them, however, aromatic polynitroso compoun...
