Abstract

The invention belongs to the technical field of rubber and discloses a UV printing rubber roller and a preparation method thereof. The UV printing rubber roller includes the following raw material components in parts by weight: 100 parts of EPDM rubber, 5-10 parts of silicone rubber, 2-15 parts of photoinitiator, 4-30 parts of ultraviolet absorber, antistatic 0.1-8 parts of softener, 10-40 parts of softener, 2.5-12 parts of active agent, 0.5-6 parts of cross-linking agent, and 0.5-5 parts of accelerator. The UV printing rubber roller provided by the present invention has the advantages of low hardness, low compression set, high rebound value, excellent wear resistance, excellent antistatic property, and good resistance to UV ink penetration. It can adapt to the working environment of UV printing equipment and meet the conditions of use of UV printing.

Description

technical field [0001] The invention belongs to the technical field of rubber, and more specifically relates to a UV printing rubber roller and a preparation method thereof. Background technique [0002] UV ink (ultraviolet curable ink) refers to an ink that undergoes an instantaneous photochemical reaction under the irradiation of ultraviolet light of a certain wavelength, and can change from liquid to solid and dry, also known as ultraviolet curable ink. UV ink has the advantages of fast drying speed, high printing production efficiency, low energy consumption for low-temperature curing, high gloss of cured film, good resistance, no solvent volatilization, and environmental protection. In recent years, based on the above-mentioned advantages of UV ink, its proportion in the offset printing industry has continued to increase, and its application has become more and more extensive. [0003] Offset printing machines using UV ink must use UV special printing rubber rollers. ...
