Embodiment 1

[0042] In this embodiment, the raw materials of phenolic-nitrile rubber thermal vulcanization adhesive consist of 7% raw nitrile rubber, 8% cashew-modified phenolic resin, 0.5% titanium dioxide, 0.5% sulfur, 1% petroleum resin, KH-5501%, hydroquinone 0.1%, the balance of methyl isobutyl ketone.

[0043] The preparation method of phenolic-nitrile rubber thermal vulcanization adhesive in the present embodiment is to operate according to the following steps:

[0044] Masticate the raw nitrile rubber on the open mill for 1-3 minutes to make the Mooney viscosity reach 60-70, then add the tackifying resin, inorganic filler, coupling agent, anti-aging agent and vulcanizing agent in sequence for mixing, and start kneading The distance between the two rollers of the machine is 1-2mm. After thinning, cut it into pieces and immediately put it into methyl isobutyl ketone for swelling. After stirring and dissolving, the glue is obtained. Add cashew modified phenolic resin to the glue and s...

Embodiment 2

[0046] In this embodiment, the raw materials of the phenolic-nitrile rubber thermal vulcanization adhesive consist of 10% raw nitrile rubber, 15% cashew modified phenolic resin, 1% light calcium carbonate, and 1% dibenzothiazole disulfide. %, rosin resin 2%, KH-570 2.5%, 2,6-di-tert-butyl-p-cresol 0.5%, the balance of methyl isobutyl ketone.

[0047] The preparation method of the phenolic-nitrile rubber thermal vulcanization adhesive in this example is the same as that in Example 1.

Embodiment 3

[0049] In this embodiment, the raw materials of phenolic-nitrile rubber thermal vulcanization adhesive consist of 8% raw nitrile rubber, 10% phenolic resin modified by cashew nuts, 0.7% white carbon black and titanium dioxide, and 0.7% diisopropyl peroxide. 0.6% of benzene, 1.5% of alkylphenolic resin, 1.5% of NDZ-102, 0.3% of hydroquinone dimethyl ether, and the balance of methyl isobutyl ketone.

[0050] The preparation method of the phenolic-nitrile rubber thermal vulcanization adhesive in this example is the same as that in Example 1.

Abstract

The invention discloses a phenolic-nitrile rubber hot vulcanized adhesive and a preparation method thereof. The adhesive consists of the following raw materials: crude nitrile rubber, phenolic resin, an inorganic filler, a vulcanizing agent, a tackifying resin, a coupling agent, an anti-aging agent and methyl isobutyl ketone. The preparation method comprises the following steps of: plasticating the crude nitrile rubber for 1 to 3 minutes on an open mill; sequentially adding the tackifying resin, the inorganic filler, the coupling agent, the anti-aging agent and the vulcanizing agent into the open mill for mixing; after plasticating the mixture, shearing the mixture; adding the sheared mixture into the methyl isobutyl ketone for swelling; after stirring and dissolving the mixture, obtaining a rubber slurry; and adding the phenolic resin into the rubber slurry to obtain the phenolic-nitrile rubber hot vulcanized adhesive after uniformly stirring the mixture.

Description

1. Technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a phenolic-nitrile rubber thermally vulcanized adhesive and a preparation method thereof. 2. Background technology [0002] Among metal structure adhesives, phenolic-nitrile rubber thermal vulcanization adhesives are the most comprehensive and widely used adhesives in today's synthetic adhesives. Since Metlbond4021, the first phenolic-nitrile rubber thermal vulcanization adhesive published in the United States in 1943, has a history of 60 years and is still widely used in aircraft manufacturing. The reason why phenolic-nitrile rubber heat vulcanizing adhesives can maintain this position is related to its following characteristics in addition to its low price: [0003] 1. Bonding various metal materials has high physical and mechanical properties in a relatively wide temperature range; [0004] 2. It has good elasticity and toughness, so it has high peel strengt...
