Abstract

The invention provides a nitrile butadiene rubber adhesive, which comprises the following components, by weight, 110-130 parts of a nitrile butadiene rubber, 50-60 parts of carbon black, 15-20 parts of a softener, 3-8 parts of zinc oxide, 0.3-0.8 part of stearic acid, 1-3 parts of sulfur, 1.0-1.2 parts of an accelerant M, and 1.0-1.2 parts of propyl gallate. The nitrile butadiene rubber adhesive of the present invention has technical effects of good adhesion effect, good oil resistance, good heat resistance and good stability.

Description

[0001] technical field [0002] The invention relates to a nitrile rubber adhesive, which belongs to the technical field of adhesives. Background technique [0003] Nitrile-butadiene rubber adhesive is made of nitrile-butadiene rubber as the main body, together with other component raw materials. Its forms are solvent type, latex type, film and tape type. They all have outstanding storage stability, good heat resistance and oil resistance, strong adhesion, good elasticity, resistance to atmospheric aging, medium resistance, fatigue resistance and good adhesion to polar surfaces, and are environmentally friendly. Adhesive materials also have good adaptability. Nitrile rubber adhesives do not degrade during aging to produce volatiles that can damage metals, plastics and fabrics like neoprene adhesives. The disadvantage is that the initial viscosity is poor, the adhesive film is difficult to coalesce with the adherend, and the vulcanization time is long, so the application...
