Problems solved by technology

However, during wide-format high-speed printing, UV generates a lot of heat, which makes the printing coating uneven. When printing on some heat-sensitive film and other substrates, the film is easily deformed.
Due to the low energy of UV light-curing coatings during curing, there are many unreacted small molecular monomers left in the cured coating. At the same time, due to the photoinitiator in the formula, there are more migratory components in the coating and the odor is relatively large. , poor film performance

Abstract

The invention discloses a low-energy electron beam radiation curing coating, which comprises the following components in percentage by weight: 40-90 percent of reactivity oligomer, 10-60 percent of reactivity monomer, 0.3-5 percent of additive, 0-30 percent of thermoplastic resin, 0-15 percent of photoinitiator and 0-30 percent of pigment and filler. The coating is particularly suitable for coating processing on substrate made of plastic or paper. A use method of the low-energy electron beam radiation curing coating comprises the following steps of: (a) printing at least one layer of the electron beam radiation curing coating on the plastic or paper substrate; (b) radiating the coating by adopting an electron beam of no more than 200+/-10kV; or repeating the use steps. The coating has low cost and good environment protection property. The coating obtained by using the low-energy electron beam radiation curing coating has good abrasive resistance, scratching resistance and solvent resistance.

Description

technical field [0001] The invention relates to a low-energy electron beam radiation-cured coating and its application method, in particular to a low-energy electron beam radiation-cured coating applied to plastic or paper substrates and its application method. Background technique [0002] Now in the printing industry, UV curing is progressing rapidly. In many low to medium speed narrow web printing applications, light curing UV is a more economical processing method. However, during wide-format high-speed printing, UV generates a lot of heat, which makes the printing coating uneven, and when printing on substrates such as some heat-sensitive films, the film is easily deformed. Due to the low energy of UV light-curing coatings during curing, there are many unreacted small molecular monomers left in the cured coating. At the same time, due to the photoinitiator in the formula, there are more migratory components in the coating and the odor is relatively large. , poor film ...
