Adhesive for producing rubber shoes and preparation method of adhesive

The invention discloses an adhesive for producing rubber shoes and a preparation method of the adhesive, which relate to the technical field of the preparation of adhesives. The adhesive is prepared from the following raw materials in parts by weight: 100 parts of national standard Number-1 natural rubber, 2.5 to 3 parts of sulfur, 1.5 to 2.5 parts of accelerant M, 0.5 to 1.5 parts of accelerant DM, 0.5 to 1.5 parts of accelerant D, 5 to 9 parts of zinc oxide or zinc carbonate, 0.5 to 1.5 parts of stearic acid, 1.5 to 2.5 parts of phenolic resin, 1.5 to 2.5 parts of rosin, 2.5 to 3.5 parts of terpene resin, 3 to 10 parts of polyisocyanate, and 350 to 450 parts of number-120 solvent oil. The adhesive is high in adhesion force, and can be connected with rubber products with any rubber content or made of different materials; the erosion and corrosion time and performance can be improved or prolonged; the temperature range adaptability is high; the bending resistance and impact resistance are good; the viscosity
