Problems solved by technology

[0005] However, due to the structural characteristics of the above-mentioned photocurable resins, the coating layer formed by curing the photocurable system as the matrix resin has no obvious advantages in adhesion, elasticity, gloss and weather resistance, and the raw materials are highly toxic.
Therefore, the application of such resins in packaging such as food, medicine and agricultural by-products is limited

Embodiment 1

[0055] The preparation method of light-cured tetrahydrophthalic anhydride tung oil acrylate resin of the present invention, described preparation method comprises the following steps:

[0056] a. Using tung oil and tetrahydrophthalic anhydride as basic raw materials, the mass ratio between tung oil and tetrahydrophthalic anhydride is 100:45, first add 100g of tung oil weighed into the four-port reaction with agitator, thermometer and reflux condenser In the container, heat the oil bath to 65°C, then add 45g of tetrahydrophthalic anhydride weighed, raise the temperature to 180°C, and carry out the Diels-Alder reaction under this temperature condition, as the reaction proceeds, the intermediate product tetrahydrophthalic anhydride Tung oil, the intermediate product that generates is carried out along with reaction, and its acid value increases gradually, and when reacting to the acid value of intermediate product tetrahydrophthalic anhydride tung oil no longer changes, reaction f...

Embodiment 2

[0058] Embodiment 2: basically the same as Embodiment 1, the difference is:

[0059] In step b: the reflux agent is 100 mL of xylene, the polymerization inhibitor is 0.1 g of p-methoxyphenol, 15 g of β-hydroxyethyl methacrylate is added, and the temperature is raised to 138 ° C for esterification reaction; 118.8 g of product are obtained : Tetrahydrophthalic anhydride tung oil methacrylate-β-hydroxyethyl ester resin (for the infrared analysis spectrum of this product, see image 3 ).

Embodiment 3

[0060] Embodiment 3: basically the same as Embodiment 1, the difference is:

[0061] In step b: 100 mL of xylene as the refluxing agent, 0.1 g of nitrobenzene as the polymerization inhibitor, and 10 g of β-hydroxypropyl acrylate are added, and the temperature is raised to 138 ° C for esterification; 113.7 g of the product is obtained: tetrahydrophthalic anhydride Tung Oil Acrylate-β-Hydroxypropyl Ester Resin.

Abstract

The invention discloses light-cured tetrahydrophthalic anhydridized tung oil acrylate resin and a preparation method thereof. The preparation method comprises the followings steps: tung oil and a tetrahydrophthalic anhydride monomer are subjected to the Diels-Alder reaction so as to produce an intermediate product, namely, tetrahydrophthalic anhydridized tung oil; and the tetrahydrophthalic anhydridized tung oil and an acrylic hydroxy ester monomer are subjected to an esterification reaction so as to prepare the product, wherein the mass ratio of the used raw materials is that the tung oil / the tetrahydrophthalic anhydride monomer / the acrylic hydroxy ester monomer is equal to 100:(45 to 55):(10-40). The product disclosed by the invention has a main chain which is a longer flexible chain, and the structural characteristics of a bonded rigid double six-membered ring; and the light-cured tetrahydrophthalic anhydridized tung oil acrylate resin is applied to the fields, such as light-cured solvent-free inks and coatings and the like as matrix resin, the rigidity, the toughness, the glossiness, the adhesive force to a base material, the weather-resisting property and the like of the inks, the coatings and the like can be adjusted within a wider range, so that the application performance is convenient to optimize and the fossil resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of photocurable resins, and in particular relates to a photocurable tetrahydrophthalic anhydride tung oil acrylate resin and a preparation method thereof. Background technique [0002] With the implementation of the strategy of "energy saving, emission reduction and sustainable development", many countries in the world are actively developing technology research and development of chemical products prepared by replacing "fossil" resources with renewable resources. Photocurable materials are an important area of ​​concern one. [0003] Using natural renewable vegetable oil to replace petroleum and other "fossil" resources to prepare light-curable materials, current research reports are mostly on soybean oil-modified light-curable resins. The new trend is that soybean oil-based resins are changing to other vegetable oil-based resins. [0004] my country is an important producer of tung oil, with an average a...
