The invention relates to the technical field of mirror ink, and discloses high-temperature-resistant mirror ink. The high-temperature-resistant mirror ink is prepared from the following components: 10-20 parts by weight of
epoxy resin, 1-2 parts by weight of a
toughening agent, 20-50 parts by weight of nano-
metal of which the particle size D100 is less than or equal to 200 nm, 30-50 parts by volume of a
solvent, 0.1-0.3 part by volume of a leveling agent, 1-3 parts by volume of a defoaming agent, 0.25-1.5 parts by volume of a
coupling agent, 0.1-0.5 part by volume of a
wetting agent, 0.05-0.2 part by volume of an anti-
settling agent, 2-10 parts by volume of a dispersant, 1-5 parts by volume of a curing agent, and 0.1-0.2 part by volume of an
ultraviolet light absorber. The mirror ink prepared by using the formula can be matched with different mesh numbers of gauzes for silk-
screen printing, the particle size of the used nano
metal powder can reach the nano level, and the nano
metal powder is uniformly dispersed into the
epoxy resin through the dispersant, so that the surface problem that a 'rime
fog' defect is formed due to
diffuse reflection on the surface can be avoided.
