AI Technical Summary

Problems solved by technology

[0003] However, traditional reflective signs mostly use lettering technology, that is, engraving films of different colors into required patterns, fonts, etc., and then laminating multiple layers to achieve pattern expression. This traditional process has low material utilization rate and extremely low lamination efficiency. , it is difficult to grasp the lamination accuracy, the labor cost is huge, and the adhesion and weather resistance between the layers are uneven.

Abstract

The invention discloses reflective film UV curing ink-jet ink as well as a preparation method and application of the reflective film UV curing ink-jet ink. The ink is prepared from the following raw materials in parts by weight: 2-5 parts of an organic pigment, 1-3 parts of a dispersing agent, 1-10 parts of acrylic resin, 10-20 parts of an UV oligomer, 60-90 parts of an UV monomer, 5-15 parts of a photoinitiator and 0.1-2 parts of a light stabilizer. The prepared UV curing ink-jet ink for the reflective film has the advantages of being good in weather resistance, high in adhesive force with the reflective film, good in gloss effect and the like. When the reflective film is formed by digital inkjet printing, the inventory can be extremely small, only a white reflective film and a small number of spot-color reflective films are reserved, pattern construction becomes simple and immediate, the yield of products is greatly improved, and therefore the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the field of reflective films, and in particular relates to a UV-cured inkjet ink for reflective films and a preparation method and application thereof. Background technique [0002] Reflective film materials are mainly used in the two categories of road traffic signs and non-road traffic signs. For example, when traffic road users (vehicles, drivers, pedestrians) pass through such identification signs, they can clearly see the outline of the reflective identification signs. If there are objects (vehicles, pedestrians) passing by Reflective signage, because it covers the reflected light, it shows the shadow outline of the object, making it easier for traffic road users (vehicles, drivers, pedestrians) to identify the type of object, thus playing a warning role; so reflective Signs and signs made of membrane materials can improve the safety performance of traffic facilities, and power system equipment and facilities can also im...
