Embodiment 1

[0019] Example 1 This example discloses the preparation of a UV-curable acrylate resin ED-4 with a hyperbranched structure

[0020] The raw material ethylenediamine (30g) was added into the reaction flask, and then 1,6-hexanediol diacrylate (460g), sodium methoxide (0.5g), and hydroquinone (0.5g) were added. After reacting at 70° C. for about 6 hours, the reaction was stopped, and after the polymerization inhibitor was washed away with 5% NaOH aqueous solution, 483 g of light yellow transparent liquid was obtained.

Embodiment 2

[0021] Example 2 This example discloses the preparation of a UV-curable acrylate resin ET-8 with a hyperbranched structure

[0022] The raw material ethylenediamine (30 g) was added into the reaction flask, and then trimethylolpropane triacrylate (TMPTA) (600 g), sodium methoxide (0.5 g), and hydroquinone (0.5 g) were added. After reacting at 70° C. for about 7 hours, the reaction was stopped, and after the polymerization inhibitor was washed away with 5% NaOH aqueous solution, 622 g of light yellow transparent liquid was obtained.

Embodiment 3

[0023] Example 3 This example discloses the preparation of a UV-curable acrylate resin EP-12 with a hyperbranched structure

[0024] The raw material ethylenediamine (30g) was added into the reaction flask, and then pentaerythritol tetraacrylate (PET4A) (710g), sodium methoxide (0.5g), and hydroquinone (0.5g) were added. After reacting at 80° C. for about 8 hours, the reaction was stopped, and after the polymerization inhibitor was washed away with 5% NaOH aqueous solution, 728 g of light yellow transparent liquid was obtained.

Abstract

The invention belongs to the field of chemical material synthesis and particularly relates to a synthesis method of ultraviolet-curing acrylate resin with a hyperbranched structure and application of the ultraviolet-curing acrylate resin in the field of paint. The method includes the step that amine monomers and acrylate monomers are subjected to a Michael addition reaction to obtain the AxBy type hyperbranched resin. The resin obtained through the method can achieve curing and cross-linking under the action of ultraviolet, and is large in molecular weight, low in volatility and small in smell. Each molecule contains multiple acrylate functional groups, the photo-curing speed of the resin is high, and the hardness of solid products is high. Besides, the resin molecules have a highly-branched three-dimensional spherical structure, the molecules are not likely to entangle, the solution viscosity is much lower than that of linear molecules with the same molecular weight, and a high-solid low-viscosity solution can be formed. The ultraviolet-curing acrylate resin with the hyperbranched structure can be applied to the fields of paint, adhesives, printing ink, 3D printing and the like, and has extremely good market prospects.

Description

technical field [0001] The invention belongs to the field of chemical material synthesis, and in particular relates to a synthesis method of an ultraviolet-curable acrylate resin with a hyperbranched structure and its application in the field of coatings. Background technique [0002] Ultraviolet (UV) curable resin has the characteristics of low energy consumption, less pollution, fast curing speed, less land occupation, and is suitable for automatic production. It is a green and environmentally friendly material (Polymer, 2001, 42, 5531), so in recent years It has developed rapidly at home and abroad. Currently, the organic components used in UV curable resins are mainly linear oligomers / polymers. However, such UV-curable resins based on linear oligomers / polymers have defects such as high shrinkage after curing, high viscosity, large amount of diluent, and poor compatibility with inorganic nanoparticles, which will adversely affect the curing of the coating.
