preparation example Construction

[0043] Please refer to figure 1 , the preparation method of the hybrid photocurable material provided by the invention comprises the following steps:

[0044] S1: Add the photoinitiator to the active monomer, heat in a water bath at a constant temperature, and stir to fully dissolve the photoinitiator to obtain a dissolved mixture;

[0045] In this step, preferably, the heating temperature is 40-50°C.

[0046] S2: Add the prepolymer and the leveling agent into the dissolved mixture, stir and mix, and let stand until the system is stable to obtain a hybrid photocurable material.

[0047] In this step, preferably, the stirring time is 30-60 min.

[0048] The equipment required for the preparation of the hybrid light-curing material of the present invention is an electromagnetic stirrer and ultrasonic dispersion equipment, and the process is simple and controllable. The light-curing material of the present invention is prepared and processed from commercially available prepoly...

Embodiment 1

[0051] Add 5 parts of initiator to 50 parts of active monomer, heat in a water bath at 50°C, and stir to fully dissolve the photoinitiator to obtain a dissolved mixture; add 30 parts of prepolymer and 5 parts of auxiliary agent to the dissolved mixture (contains 1 part of leveling agent TEGO RAD 2700, and the rest are dispersants, such as modified acrylate block copolymers, alkene acid block copolymers or hyperdispersants with anchor groups, the same below) After stirring the mixture with a magnetic stirrer for 30 minutes to disperse, it is ready.

[0052] Wherein, wherein the prepolymer is a polyester acrylic resin, selected from V400 produced by Allnex Resin Co., Ltd., and the active monomer is a mixture of EOEOEA produced by Tianjiao Chemical Co., Ltd. and EM221 produced by Changxing Chemical Industry Co., Ltd., and the ratio is =2:3 (weight ratio), the initiator is JR-910 from Tianjin Jiuri Chemical Co., Ltd.

Embodiment 2

[0054] Add 5 parts of initiator to 45 parts of active monomer, heat at 40°C in a water bath, and stir to fully dissolve the photoinitiator to obtain a dissolved mixture; add 35 parts of prepolymer and 5 parts of auxiliary agent to the dissolved mixture After portioning, use a magnetic stirrer to stir the mixture for 30 minutes to disperse and obtain.

[0055] Among them, the prepolymer is polyester acrylic resin, which is selected from CN2302 produced by Sartomer Chemical Co., Ltd., and the active monomer is EOEOEA produced by Tianjiao Chemical Co., Ltd., EM221 produced by Changxing Chemical Industry Co., Ltd., and Tianjiao Chemical Co., Ltd. The mixture of TMPTA produced by Co., Ltd., the ratio is =2:3:1 (weight ratio), and the photoinitiator is selected from JR-910 and TPO of Tianjin Jiuri Chemical Co., Ltd., and the ratio is =1:1 (weight ratio).

Abstract

The invention provides a hybrid light curing material for production of a flexible plate as well as a preparation method and application of the hybrid light curing material, and belongs to the technical field of radiation curing. The hybrid light curing material comprises the following raw materials by weight: 20 to 50 parts of one or more prepolymers, 30 to 50 parts of one or more active monomers, 3 to 5 parts of one or more photoinitiators, and 0.5 to 1 part of a leveling agent, is 20 to 30 cP in viscosity at 25 DEG C, 20 to 30 mN/m in surface tension at 25 DEG C, 40 to 50 m/min in curing speed while the light source linear power 200 W/cm, 1 to 3 mm in flexibility, and about 3 percent in volumetric shrinkage, and can meet the requirements of a 3-dimensional printing flexible plate. The defects of serious environmental pollution, high resource waste, complex production technology and the like in the conventional flexible platemaking technology are overcome.

Description

technical field [0001] The invention relates to the field of radiation curing technology, in particular to a hybrid light-curing material for making a flexographic plate based on 3D printing technology and a preparation method thereof. Background technique [0002] Flexographic printing is a printing plate that produces a convex image mirror image on polyester or other polymer materials. The ink is transferred to the printing plate, and the surface of the printing plate is in contact with the substrate during rotation, thereby transferring the image and text a printing method. Compared with several other printing methods, flexographic printing has unique flexibility and economy, and is beneficial to environmental protection. It meets the hygienic requirements of food packaging printed matter, and can complete printing, gluing, die-cutting and ironing on-line with the post-press processing process. Printing and other processing to reduce costs and improve production efficien...
