China is very rich in rare earth resources, rare earth luminescent materials have many varieties and are widely used. The rare earth luminescent materials can be combined with ink to make photoluminescent safety signs through screen printing, and according to the different requirements of the use of location, environment and customers, the use of PVC rigid low-foam polyvinyl chloride sheet or flame-retardant ABS material to make fire signs. The development of photoluminescent safety signs in China has broad prospects, and its social and economic benefits are inestimable. In the past, most of the luminescent safety signs used thermosetting luminescent inks, which have the shortcomings of large solvent volatiliation, complex process, time consuming and large energy consumption, so the development of a simple process, clean environmental protection and energy saving ink has become the focus of attention.
The combination of UV curing ink and rare earth luminescent materials to prepare UV glossy ink can make the printing process clean and environmentally friendly, low energy consumption, suitable for continuous production, and UV curing product performance is excellent, in gloss, wear resistance, hardness, solvent resistance, beauty and other curing methods incomparable excellent quality. UV luminous ink is a new type of ink suitable for modern industrial production.
