Abstract

The invention discloses a heat vulcanization adhesive for bonding vulcanized rubber or thermoplastic rubber with a hard panel. The heat vulcanization adhesive contains single-nitrosophenol-closed methylbenzene-2,4-diisocyanate, halogenated rubber, metal oxide such as zinc oxide or magnesium oxide, an inertia pigment filler such as carbon black or titanium dioxide, a solvent such as aromatic hydrocarbon, a chloridized solvent or a ketone solvent, a polymaleimide compound such as N,N'-interphenylene bismaleimide or diphenylmethane bismaleimide and a vulcanizer such as sulphur, selenium or tellurium. The heat vulcanization adhesive disclosed by the invention has the greatest characteristic that the single-nitrosophenol-closed methylbenzene-2,4-diisocyanate is contained, so that an aromatic polynitro compound easy to sublimate or a highly toxic polyisocyanate monomer is not used; and the heat vulcanization adhesive has 'preheating-resistant' performance or is applicable to requirements of an injection moulding process.

Description

[0001] technical field

[0002] The present invention relates to a thermal vulcanization adhesive containing mononitrosophenol-blocked toluene-2,4-diisocyanate, which is used for bonding vulcanized rubber or thermoplastic rubber to hard plates.

[0003] technical background

[0004] A number of adhesive compositions have been developed to provide bonding to various materials or objects such as elastomeric substrates and metal surfaces. However, most of these rubber-metal adhesives contain aromatic polynitroso compounds or polyisocyanate monomers.

[0005] 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 polyol...
