摘要

PURPOSE: A road signal composition is provided to ensure excellent adhesive force and water resistance even in the continued exposure in an atmospheric condition, and to prevent cracks and discoloration even in the continued load of vehicles. CONSTITUTION: A road signal composition includes a base material, 60~140 parts by weight of constructional aggregate powder, 30~60 parts by weight of ceramics aggregate having a return reflection function, 50~60 parts by weight of filler, 20~60 parts by weight of glass beads, 15~20 parts by weight of wax, 1-5 parts by weight of antioxidant, 1-5 parts by weight of UV stabilizer, 1~2 parts by weight of carbon fiber chops and 1~1.5 parts by weight of color pigment. The base material includes 65-75 weight% of terephthalic acid-modified polyamide resin, 15-25 weight% of rosin ester resin, 3-7 weight% of ethylene vinyl acetate copolymers and 3-5 weight% of polyethylene.
