Abstract

The invention discloses a method for preparing photocurable resin from animal and vegetable triglyceride and the photocurable resin prepared by the method. The preparation method comprises the following steps of: performing alcohol exchange reaction on the animal and vegetable triglyceride and polylol containing at least three hydroxyl groups to get hydroxylated fatty acid glyceride; performing graft reaction on the obtained hydroxylated fatty acid glyceride and a styrene-maleic anhydride copolymer under the action of a catalyst to graft the hydroxylated fatty acid glyceride on the styrene-maleic anhydride copolymer; enabling a grafted product to react with acrylic ester type or methacrylic acid type monomers containing the single hydroxyl group, and opening the remaining acid anhydride bonds on the grafted product to get the grafted product containing an acrylic ester group; and finally adding a terminated monomer containing an epoxy group for reaction, and closing a carboxyl group in the grafted product to get the photocurable resin. The method provides a new way for transforming animal and vegetable grease to the photocurable resin.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a method for preparing photocurable resin from animal and vegetable triglycerides and the prepared photocurable resin. Background technique [0002] Although animal fats and vegetable fats come from a wide range of sources and have many names, their basic structure is the so-called triglyceride formed by saturated fatty acids, unsaturated fatty acids and glycerin. These fatty acids include stearic acid, palmitic acid, palmitoleic acid, oleic acid , linoleic acid, linolenic acid, alpha-tungic acid, ricinoleic acid, etc., that is, the main component of animal and vegetable oil after preliminary purification is a mixture of various fatty acid triglycerides. There are many technical reports on the modification of triglycerides into raw materials for coatings, but most of them are aimed at vegetable triglycerides with a high degree of unsaturation, and for animal triglycer...
