Embodiment 1

[0017] Embodiment 1, 100Kg acrylonitrile-butadiene 3350 rubber is put into open type rubber mixer and masticated 4 times, then add carbon black N330 45Kg, stearic acid 2Kg, zinc oxide 2Kg, DM 0.5Kg, sulfur, DCP each 0.5Kg, Mix 6 times on the internal mixer, slice it, then add it to the solvent of methyl isobutyl ketone 450Kg, butyl ester 300Kg, ethyl ester 50Kg, add phenolic resin 2402 65Kg at the same time, stir and disperse, and mix evenly Finally, stir and disperse evenly, and then put it into a sand mill for sanding for 2 times. After the sanding is completed, it is filtered through a filtration system to obtain a nitrile rubber coating.

[0018] It is coated on the surface of the substrate by scraping, and then it is surface-dried at 60°C for 10 minutes, and vulcanized without pressure at 180°C for 10 minutes to make a metal-rubber composite board.

Embodiment 2

[0019] Embodiment 2, put 100Kg nitrile butadiene 3350 rubber into the open rubber mixer and masticate 4 times, then add carbon black N300 60Kg, stearic acid 4Kg, zinc oxide 3.5Kg, DM 0.5Kg, sulfur 2Kg, in banburying Mixed on the machine for 6 times, sliced, and then added to a solvent of 600Kg of methyl isobutyl ketone, 400Kg of butyl ester, and 100Kg of ethyl ester, and at the same time added 50Kg of phenolic resin 2402 and 50Kg of modified phenolic resin T6000 for stirring and dispersing , after being mixed evenly, stir and disperse evenly, then put it into a sand mill for sanding for 2 times, after the sanding is completed, filter through a filter system to obtain acrylonitrile-butadiene rubber coating.

[0020] It is coated on the surface of the substrate by scraping, and then it is surface-dried at 60°C for 10 minutes, and vulcanized without pressure at 180°C for 10 minutes to make a metal-rubber composite board.

Embodiment 3

[0021] Embodiment 3, 80Kg nitrile butadiene 3350 rubber, 20Kg carboxylated nitrile butadiene are put into open rubber mixer and masticated 4 times, then add carbon black N330 30Kg, stearic acid 0.3Kg, zinc oxide 0.3Kg, DM 0.1Kg, Each 0.15Kg of sulfur and DCP was mixed 6 times on the internal mixer, sliced, and then added to a solvent of 250Kg of methyl isobutyl ketone, 200Kg of butyl ester, and 50Kg of ethyl ester, and at the same time, 30Kg of phenolic resin 2402 was added to carry out Stir and disperse. After mixing evenly, stir and disperse evenly, and then put it into a sand mill for sanding for 2 times. After sanding, it is filtered through a filter system to obtain nitrile rubber coating.

[0022] It is coated on the surface of the substrate by scraping, and then it is surface-dried at 60°C for 10 minutes, and vulcanized without pressure at 180°C for 10 minutes to make a metal-rubber composite board.

[0023] The above products were sampled and tested, and compared with ...

Abstract

The invention discloses a non-pressure cured nitrile-butadiene rubber paint. The invention is characterized in that the non-pressure cured nitrile-butadiene rubber paint is prepared by compounding the following raw materials in parts by weight: 100 parts of nitrile-butadiene rubber, 30-60 parts of carbon black, 1-10 parts of vulcanizing agent and assistant, 30-100 parts of phenolic resin and 500-1100 parts of organic solvent. The non-pressure cured nitrile-butadiene rubber paint can be cured at a certain temperature without pressurization, and has the advantages of favorable surface hardness, favorable adhesiveness and favorable self antisticking property; the non-pressure cured nitrile-butadiene rubber paint can be used for preparing materials for shock absorption, sealing, sound insulation and the like in the fields of motor vehicles, refrigeration, petroleum, chemical engineering, compressors and the like, and can also be used for preparing a metal-rubber composite plate; and the prepared metal-rubber composite plate has favorable shock absorption property, noise reduction property, sealability, high temperature resistance, oil resistance and non-freezing solution resistance.

Description

technical field [0001] The invention relates to the technical field of rubber coatings, in particular to a pressureless vulcanized nitrile rubber coating and a preparation method thereof, which can be used for materials such as shock absorption, sealing, and sound insulation in the fields of motor vehicles, refrigeration, petroleum, chemical industry, and compressors. preparation. Background technique [0002] Nitrile rubber has good oil resistance, abrasion resistance, heat resistance and adhesive properties, and is widely used in the production of oil-resistant products, as well as rubber sheets and wear-resistant parts. But most of them are pressure vulcanized products. When there is no pressure vulcanization, the rubber coating has poor density and the utilization rate of the vulcanizing agent is low, resulting in low hardness of the rubber surface and easy scratches, poor solvent resistance, and easy self-adhesion, which cannot meet the requirements of high-end products...
