Abstract

The invention discloses the synthesis of epoxy camellia oil monomer, polymer and pressure-sensitive adhesive thereof, and relates to the technical field of polymer material preparation. The epoxy camellia oil monomer has the following structural formula: the present invention also provides the above-mentioned epoxy camellia oil monomer The preparation method of above-mentioned epoxy camellia oil monomer copolymer is used as the application of pressure-sensitive adhesive. The beneficial effects of the present invention are: the epoxy camellia oil monomer prepared in the present invention is used to copolymerize with the nucleobase material to obtain polymers of different proportions, and the obtained polymers have good adhesion properties and biocompatibility, and can be applied For vegetable oil-based pressure sensitive adhesives.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to an epoxy camellia oil monomer, a polymer based on the monomer, a pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] With the depletion of petrochemical resources and the increasingly serious environmental pollution, the development and application of biomass materials have attracted much attention. Vegetable oil, especially woody vegetable oil, including tung oil and camellia seed oil, is an important renewable resource and has been widely used in the preparation of polymer materials. [0003] Epoxy vegetable oil is mainly used as polyvinyl chloride plasticizer and stabilizer. It has good thermal and light stability, water resistance and oil resistance, and has good compatibility, low volatility and small migration. It has developed into the first Three types of plasticizers. [0004] The production of epoxy vegetabl...
