Embodiment Construction

[0006] 1. First, tung oil is hydrolyzed under high pressure to obtain α-tungoleic acid.

[0007] 2. Addition reaction of 2mol maleic anhydride (or fumaric acid) and 1mol α-manoleic acid conjugated double bond at a reaction temperature of 200-240°C can produce cis (or trans)butenediolic acid .

[0008] 3. Then use 4~5mol hydroxyethyl acrylate (HEA) or hydroxypropyl acrylate (HPA) or hydroxyethyl methacrylate (HEMA) or hydroxypropyl methacrylate (HPMA) to esterify the added oleic acid Chemical reaction, the reaction temperature is 160 ~ 200 ℃, after the reaction is complete, several kinds of highly active maleic anhydride tung oil pentaacrylic acid photocurable resin with 4 to 5 functionalities are obtained.

Abstract

The invention discloses a photocurable maleic anhydride tung oil acrylic resin and a preparation method thereof. The technical scheme is as follows: the photocurable maleic anhydride tung oil acrylic resin comprises the following components: 1 mol of elacostearic acid, 2 mol of maleic anhydride (fumaric acid) and 4-5 mol of hydroxy acrylic monomer. The preparation method comprises the following steps: hydrolyzing tung oil at high pressure so as to obtain alfa-elacostearic acid, carrying out addition reaction on the maleic anhydride or the fumaric acid and a conjugated double bond of the alfa-elacostearic acid to generate a maleic / fumaric elacostearic acid, and then carrying out esterification reaction on hydroxyethyl acrylate (HEA), hydroxypropyl acrylate (HPA), hydroxyethyl methacrylate (HEMA) or hydroxypropyl methacrylate (HPMA) and the maleic / fumaric elacostearic acid to obtain various high-activity photocurable maleic anhydride tung oil penta-acrylic resins with 4-5 functionalities. The photocurable maleic anhydride tung oil acrylic resin has the characteristics of environment friendliness, no solvent, hydrolysis resistance and the like; and the paint film has excellent hardness and flexibility; as renewable resources are used for replacing a part of petrochemical products, and after the workpieces painted with the resin are discarded, the paint film is easy to degrade, and the harm of the pure chemical coating film to the environment is avoided; and after the resin is added with a photoinitiator, various photocureable coatings, printing ink and the like can be prepared.

Description

technical field [0001] The invention belongs to a synthetic resin for UV. Background technique [0002] As we all know, UV resins widely used at present are composed of polymer monomers and prepolymers, which are highly irritating, corrosive, and toxic. While various companies are constantly improving the performance of UV coatings, they have not reduced their hazards correspondingly. measures. After searching the relevant patented technologies, there are not many corresponding patented technologies in this aspect, so this solution is proposed. The scheme aims to reduce the harm of UV resin to the human body, and use renewable resources to replace some petroleum products. The workpieces coated with this product can be degraded after being discarded, and will not cause harm to the environment like pure chemical coatings. Contents of the invention [0003] The purpose of the present invention is to provide a kind of photocurable maleic anhydride (or fumaric acid) that can ...
