This invention belongs to the field of adhesive technology, specifically relating to a castor oil-based polyester pressure-sensitive adhesive and its preparation method. The preparation method of the castor oil-based polyester pressure-sensitive adhesive provided by this invention involves introducing maleic anhydride into dehydrated castor oil via the Diels-Alder reaction, followed by epoxidation treatment of the remaining unreacted non-conjugated double bonds. This simultaneously introduces both anhydride and epoxy functional groups onto the same triglyceride backbone. This preparation strategy reduces dependence on exogenous epoxidized soybean oil and other components, facilitating the construction of a highly cross-linked polyester network dominated by ester bonds, thereby improving adhesive strength. Furthermore, the epoxidation reaction effectively eliminates residual unsaturated double bonds, reducing the risk of aging in the later stages of the pressure-sensitive adhesive. Therefore, the castor oil-based polyester pressure-sensitive adhesive prepared by this invention possesses both excellent adhesive strength and anti-aging properties, and has broad application prospects in the field of high-performance pressure-sensitive adhesive preparation.
