Embodiment Construction

[0038] 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.

[0039] The heat vulcanizable adhesives of the present invention were prepared as follows:

[0040]

[0041]

[0042]

[0043]

[0044]

[0045] To prepare test specimens, grit-blasted steel sheets were degreased with perchlorethylene vapor and dried. The steel sheet is prepared according to the requirements of GB / T 7760-2003, with a thickness of 1.5mm±0.1mm. If plastic sheets or other sheets are used, the thickness is appropriately increased. The width of the steel sheet is 25mm±0.1mm, and the length is 60mm±1mm. Before the adhesive is applied, 17.5 mm and 17.5 mm at the ends of the steel sheet test piece are masked to prevent this area from being available for bonding to the rubb...

Abstract

The invention discloses a hot vulcanization adhesive which comprises benzyloxygen resin, halogenated rubber, a metal oxide such as zinc oxide or magnesium oxide, an inert dye filler such as carbon black, titanium dioxide or gas-phase silicon oxide, a solvent such as aromatic hydrocarbon, chlorination solvent or ketone solvent, a polymaleinimide compound such as N.N'-m-phenylene bismaleimide or diphenylmethane bismaleimide, a vulcanizing agent such as sulfur, selenium or tellurium. The hot vulcanization adhesive has the most outstanding characteristic that phenolic resin containing free phenol is avoided; and meanwhile the hot vulcanization adhesive can be used as a base coating for adhering vulcanized rubber or thermoplastic rubber to a hard board, and also can be singly coated to adhere butyronitrile rubber to the hard board.

Description

[0001] technical field [0002] The invention relates to a thermally vulcanized adhesive containing phenoxy resin. The thermally vulcanized adhesive can be used as a primer for bonding vulcanized rubber or thermoplastic rubber to a hard board, and can also be used as a single coating to bond acrylonitrile-butadiene rubber and a hard board. [0003] technical background [0004] There are many primers for heat vulcanized adhesives for bonding vulcanized rubber or thermoplastic rubber to rigid boards, and one-coat adhesives for bonding nitrile rubber to rigid boards. For example, CN94194821.8 of Lauder Company discloses a kind of adhesive composition containing chlorinated polyolefin and phenolic resin, and this adhesive is used for primer. Lord Company CN93105100.2 discloses a single-coated water-based adhesive composition for bonding nitrile rubber. The adhesive contains chlorosulfonated polyethylene latex, polyhydric phenolic resin copolymer and high molecular weight alde...
