Abstract

The invention relates to polycyclic amine modified (branched) polyether acrylate and a preparation method and application thereof. The polycyclic amine modified (branched) polyether acrylate is prepared by taking heteropolycyclic amine with diphenyl ketone and polycyclic tertiary amide structure as a modifier for Michael addition reaction and introducing the polycyclic tertiary amide structure into part of double bonds of (branched) polyether acrylate. The polycyclic amine modified (branched) polyether acrylate is low in viscosity and curing shrinkage rate and high in curing speed, overcomes the defect that conventional active amine is large in smell, prone to amide migration and yellowing and is a photocuring material having great prospect.

Description

technical field

[0001] The invention relates to the technical field of radiation curable materials, in particular to a polycyclic amine modified (branched) polyether acrylate and its preparation method and application. Background technique

[0002] It is well known that aliphatic tertiary amines can be used as co-initiators to form composite initiators with hydrogen-abstracting photoinitiators benzophenone (BP) or heterocyclic aromatic ketones to synergistically promote the production of active free radicals and Effectively reduce the oxygen inhibition effect, thereby increasing the UV curing rate, and contribute to the complete curing of the deep layer and the surface layer. However, most of the existing active amines are small molecular amines, such as diethylamine, dipropylamine, di-n-butylamine, etc., which are obtained by tertiary amination of part of the double bonds of polyfunctional monomers through Michael addition reaction, such as TMPTA or Active amine modified b...
