Abstract

The invention discloses photosensitive resin based on vegetable oil and citric acid as well as a preparation method and application thereof. The preparation method comprises the following steps: reacting vegetable oil with maleic anhydride to generate maleic anhydride vegetable oil; then carrying out anhydride ring-opening modification on the generated maleic anhydride vegetable oil by utilizing citric acid to obtain vegetable oil-based polycarboxylic acid; modifying the generated vegetable oil-based polycarboxylic acid compound by using glyceryl methacrylate to obtain a vegetable oil-based polypropenyl ester prepolymer; and finally, adding a vinyl diluting monomer, and uniformly dispersing the components to obtain a final product. The photosensitive resin has excellent mechanical, thermaland coating properties after photocuring, and can be used for photocuring coatings, printing ink and the like. The method is simple in process and environmentally friendly, most of the raw materialscome from renewable resources, and therefore the method has great significance in promoting sustainable development of the light-cured material industry.

Description

technical field [0001] The invention belongs to the field of photocurable materials, and in particular relates to a photosensitive resin based on vegetable oil and citric acid, a preparation method and application thereof. Background technique [0002] Ultraviolet (UV) curing technology has 5E characteristics such as high efficiency, energy saving, wide adaptability, economy, and environmental protection. The application of these technologies has formed a new high value-added industry. The preparation of light-curing materials from natural renewable, widely sourced, low-cost and biodegradable biomass resources can not only increase the added value of biomass resources, but also reduce the dependence of the light-curing material industry on petroleum resources and reduce environmental pollution. pollute. Some biomass resources, such as vegetable oil, have abundant output and varieties, but the application of most oils and fats stays at the primary product stage, with backwa...
