Abstract

The invention discloses a fully-compatible ink-jet printing flame-retardant front-spraying lamp sheet which is characterized in that a back coating is arranged on the back surface of a base material,a bottom coating agent layer is arranged on the front surface of the base material, and a fully-compatible ink-jet printing flame-retardant coating is arranged on the bottom coating agent layer; the fully-compatible ink-jet printing flame-retardant coating is prepared from flame-retardant modified acrylic resin emulsion, and a halogen-free flame retardant, an anti-dripping agent, a smoke suppressor, a leveling agent and an anti-foaming agent are added; the bottom coating agent layer is made of a water-based two-component polyurethane binder; the base material is a transparent PET film; the lamp sheet has the advantages that various ink printing can be compatible; the coating is high in ink absorption speed, capable of adapting to high-speed printing and high in color rendition degree; thelamp sheet is waterproof, ultraviolet-proof, not easy to fade, super-strong in weather resistance, high-temperature-resistant, low-temperature-resistant, high in flatness, high in tensile strength andlong in service life; the lamp sheet is white, fine, semitransparent and uniform in light transmittance, and the light transmittance reaches 50-60%; the flame retardant property is good, the fire isextinguished immediately after leaving the fire, no obvious molten drops exist, and less combustion smoke is generated.

Description

technical field

[0001] The invention belongs to the technical field of printing, and in particular relates to a fully compatible ink-jet printing flame-retardant positive blowtorch sheet. Background technique

[0002] Digital advertising light film—PET digital blowtorch light film is a form of light film that has appeared in recent years. It is a light film made with high-precision commercial printing equipment, which is different from laser light film made by large-scale film washing equipment in the past. The positive blowtorch film is coated with transparent PET or white PET, and the thickness is generally divided into 150, 175, 200 microns and so on.

[0003] Most of the blowtorch films are made of high-quality PET substrates, which require strong printing compatibility (suitable for outdoor solvent-based inkjet printers and weak-solvent printers, UV printers), uniform coating, good ink absorption performance, white and delicate picture quality, and high color reproducti...
