Embodiment 1

[0017] Synthesis of unsaturated polyester amide urea resin:

[0018] Mix 0.1mol maleic anhydride, 0.1mol phthalic anhydride, 0.05mol urea and 0.15mol polyethylene glycol 400, put it into a 250mL three-neck flask with a water separator, place it in a silicone oil bath, stir it electrically, and set it at 100°C Mix for 20 minutes. The temperature was raised to 150°C, melted and polymerized in a nitrogen atmosphere for 40 minutes, then heated to 180°C, melted and polymerized in a nitrogen atmosphere for 120 minutes, then heated to 200°C, vacuumed, and melted and polymerized in a nitrogen atmosphere. When the distilled reaction water reaches 90% of the theoretical amount, add pentaerythritol triallyl ether with a mass fraction accounting for 4% of the total amount of the above monomers, heat and react at 190°C for 60-120 minutes, and then add a mass fraction accounting for the total amount of the above monomers Measure 3% cinnamic acid, heat reaction at 190°C for 60-120min, stop ...

Abstract

The invention provides a water-based self-initiating visible light curable resin, and a preparation method and application thereof. The water-based self-initiating visible light curable resin has a structure as shown below in the specification, wherein R is HC=CH; R' is CH2CH(CH3) or (CH2CH2O)P; R'' is (CH2)4 or a benzene ring which is in ortho-position connection with a molecular chain; X is a residue formed after an esterification reaction is performed on hydroxyl of pentaerythritol triallyl ether; Y is a residue formed after an esterification reaction is performed on carboxyl of cinnamic acid; and m/n=1/2.5-2.5/1, s/n=1/2.5-2.5/1, m/s=1/2.5-2.5/1, (m+s)/n=1/5-5/1, and X/Y=1/5-5/1. The preparation method comprises the following steps: mixing dibasic acid, dibasic alcohol and urea; performing a heating reaction at 160-210 DEG C in a nitrogen protective atmosphere for 200-600 minutes; then removing the moisture through distillation; adding the pentaerythritol triallyl ether, and performing a heating reaction at 160-210 DEG C for 60-120 minutes; adding the cinnamic acid, and performing a heating reaction at 160-210 DEG C for 60-120 minutes; and performing cooling. The unsaturated polyester-urea resin provided by the invention has a self-initiating property, also has water solubility and a visible light curing property, and is used for preparation of a water-based self-initiatingvisible light curable paint.

Description

technical field [0001] The invention belongs to the technical field of macromolecular materials, and in particular relates to a water-based unsaturated polyester amide urea resin capable of self-initiating visible light, a preparation method and application thereof. Background technique [0002] Photocuring (including ultraviolet light, visible light, electron beam) materials (including coatings and varnishes) is efficient, fast and energy-saving, and is an important direction for the development of coatings and varnishes. The popular oily UV curing (UV) materials on the market are composed of oily UV resins, oily UV monomers, photoinitiators, and diluents (organic solvents). Among them, except for oily UV resins, oily UV monomers are toxic and carcinogenic , Thinners such as toluene are toxic and VOC components, a waste of resources, and easily combine with dust in the air to form aerosols, resulting in smog. The European Union banned the production of oil-based paint 10 y...
