Adhesive for outdoor sports shoes

Abstract

The invention discloses an adhesive for outdoor sports shoes. The adhesive comprises, by weight, 3-8 parts of a modified rapeseed oil / montmorillonite nano-composite fat liquor, 10-20 parts of a natural silk protein emulsion, 5-15 parts of natural flax oil modified waterborne polyurethane, 2-5 parts of ammonium persulfate modified carbon black, 20-30 parts of casein-based soap-free core-shell composite latex, 8-16 parts of silica sol, 2-5 parts of magnetic microspheres and 1-3 parts of an emulsifier. The adhesive prepared in the above way has the advantages of high environmental protection property, harmlessness to the health of human bodies, and excellent waterproof performance and wear resistance.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive used for outdoor sports shoes.
