The invention discloses an alcohol-soluble self-crosslinking acrylic resin adhesive and a preparation method thereof. The alcohol-soluble self-crosslinking acrylic resin adhesive is prepared through a synthesis process line which adopts absolute ethyl alcohol as a solvent, performs solution polymerization on a double-bond alkene comonomer and a crosslinking agent in the presence of an initiator and adds tackifying resin in the later period. According to the method, a later crosslinking structure is introduced into a polymer structure through a silane coupling agent, thus the bonding strength and water resistance of the adhesive are improved; and the acrylic resin adhesive prepared by the method has the advantages of low toxicity, light color, high solid content, good peel strength and water resistance and excellent storage stability, and overcomes the defects of high toxicity, strong pungent smell and the like of a traditional solvent type adhesive, thereby being an environment-friendly adhesive. |
