Single-component neoprene adhesive suitable for bonding automobile leather

The invention belongs to the field of manufacturing of automobile parts, and particularly relates to a single-component neoprene adhesive suitable for bonding automobile leather, which comprises the following components in parts by weight: 40-85 parts of modified neoprene emulsion; 10-20 parts of tackifying resin emulsion; 0.1-0.4 parts of a magnesium oxide aqueous solution; 0.1-0.4 parts of an anti-aging agent; 2-5 parts of a filler; 0.5-1 part of an accelerant; and water which is added until the solid content is 20-25%; The modified neoprene emulsion is an emulsion of a product obtained by grafting a neoprene emulsion with allyl polyoxyethylene ether, and the solid content of the modified neoprene emulsion is 35-40%. The mass ratio of the allyl polyoxyethylene ether to neoprene in the neoprene emulsion is (0.02-0.1): 10, the neoprene emulsion is Dispercoll C74, and the solid content is 58 +/-0.5%. The adhesive does not contain an organic solvent and has better initial adhesion, normal state, temperature gap
