7. The composition of the two-component reticle coating according to claim 1, wherein the filler is at least one of talc, light calcium carbonate and wet-process sericite powder.
8. The composition of the two-component reticle coating of claim 1, wherein the silane coupling agent is KH550 or KH 560; the dispersant is BYK-181 or BYK-187; the leveling agent is BYK-310 or BYK-354; the defoaming agent is BYK-025.
9. The method of preparing a composition for a two-component reticle coating according to any one of claims 1 to 8, comprising the steps of:
(1) weighing the raw materials according to the proportion;
(2) preparation of component A: uniformly stirring the nano zinc oxide loaded graphite oxide, the modified hollow glass beads, titanium dioxide, a silane coupling agent, a filler, a pigment, a dispersing agent, a flatting agent and a defoaming agent, adding acrylic resin and polycaprolactone polyol, and then dispersing at a high speed for 40-60min at a stirring speed of 2000-3000 r/min; thus obtaining the component A.
(3) And B component is ready for use.
