Problems solved by technology

And because the outdoor weather resistance of the dye is poor, long-term outdoor use will cause the window film to fade, the transparency will decrease, and the appearance will not be beautiful, so the service life of the window film will be shortened, and the dye itself has no heat insulation and UV insulation properties.
At the same time, dyes are expensive and pollute during production, which limits the application range of dye-based window films

Abstract

The invention relates to a special UV curable coating for a PET window film and a preparation method of the pigment-type UV curable coating. The special UV curable coating for the window film comprises the following components in parts by mass: 3-40 parts of UV monomers, 10-50 parts of modified acrylic ester, 1-10 parts of a photoinitiator, 0.4-2 parts of a flatting agent, 3-20 parts of pigment, 0.5-1.5 parts of a coupling agent and 0.4-0.8 part of a dispersing agent. The pigment type window film disclosed by the invention is not easily faded, is UV-resistant and also has very excellent outdoor weather resistance. The color or hue of the pigment can be kept unchanged for several years and even more than ten years, so that the original color of a PET window film produced by using the pigment with good weather resistance can be kept unchanged for several years and more than ten years, and the performances of the window film cannot be influenced by outdoor environmental factors.

Description

technical field [0001] The invention relates to the use of weather-resistant transparent pigments in light-cured coatings, in particular to a special UV coating for PET window films and a preparation method thereof. Background technique [0002] Plastic window film coatings are mainly used in automobiles and buildings. The functions of window films coated with window film coatings include adjusting the intensity of visible light in the room, reducing eye irritation, and blocking ultraviolet and infrared rays in sunlight. Reducing the entry of outdoor rays can avoid the exposure of harmful rays to the human body, reduce the possible damage to interior decoration, reduce the incidence of infrared rays, and also reduce the indoor temperature and save energy. [0003] Modern window film production processes include roller coating or metal sputtering. The metal sputtering process uses the principle of electric field and magnetic field to uniformly sputter metal particles on a hi...
