Abstract

The invention discloses a nitrile butadiene rubber adhesive. The nitrile butadiene rubber adhesive is composed of the following components by weight: 30-50 parts of nitrile butadiene rubber, 20-40 parts of white carbon black, 10-20 parts of vinyl perchloride, 3-5 parts of sulfur, 10-20 parts of carbon disulfide, 100-200 parts of methylene dichloride, 3-5 parts of zinc oxide, 2-4 parts of accelerant M and 10-20 parts of cyclohexylamine. Compared with a conventional nitrile butadiene rubber adhesive, the nitrile butadiene rubber adhesive provided by the invention has the advantages of high bonding strength, wide application scope, excellent heat resistance, oil resistance and weather resistance.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and more specifically relates to a nitrile rubber adhesive. Background technique [0002] NBR latex or NBR can be prepared by emulsion polymerization of butadiene and acrylonitrile. Due to the different content of acrylonitrile and stabilizer, there are various commercial brands. [0003] In nitrile rubber, increasing the content of acrylonitrile can further improve the oil resistance, but the cold resistance will decrease accordingly. In addition, nitrile rubber has strong adhesion to hydrophilic substances, and its films and adhesives have high mechanical strength, which is very suitable for adhesives. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a nitrile rubber adhesive. [0005] To achieve the above object, the present invention has taken the following technical solutions: [0006] A nitrile butadi...
