Embodiment 1

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

[0043] The preparation method of the phenolic-nitrile rubber thermally vulcanized adhesive in this embodiment is as follows:

[0044] The raw nitrile rubber is masticated on an open mill for 1-3 minutes to make the Mooney viscosity reach 60-70, and then tackifying resin, inorganic filler, coupling agent, anti-aging agent and vulcanizing agent are added in sequence for mixing. The distance between the two rollers of the machine is 1-2mm. After being thinned, cut into pieces and immediately put into methyl isobutyl ketone to swell, stir and dissolve to obtain a glue, add cashew modified phenolic resin to the glue, and stir evenly Then, the phenolic-nitrile rubber hot-vu...

Embodiment 2

[0046] In this embodiment, the raw materials of the phenolic-nitrile rubber thermally vulcanized 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%, methyl isobutyl ketone balance.

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

Embodiment 3

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

[0050] The preparation method of the phenolic-nitrile rubber thermally vulcanized adhesive in this example is the same as that of 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 thermal vulcanization adhesive and a preparation method thereof. 2. Background technology [0002] Among the metal structural adhesives, phenolic-nitrile rubber thermal vulcanization adhesives are the most comprehensive and versatile adhesives among synthetic adhesives today. Since the United States published the first phenolic-nitrile rubber hot-vulcanized adhesive Metlbond 4021 in 1943, it has a history of sixty years and is still widely used in aircraft manufacturing. The reason why the phenolic-nitrile rubber hot-vulcanized adhesive can maintain this position is related to its following characteristics: [0003] 1. Bonding various metal materials in a relatively wide temperature range, with high physical and mechanical properties; [0004] 2. It has good elasticity and toughness, so it has high peel strength, impact strength and fatigue per...
