NOVELTY - A nano heat-insulating and temperature-reducing coating comprises 20-40 pts. wt. epoxy acrylate resin, 10-20 pts. wt. nano silicon dioxide, 10-15 pts. wt. nano titanium dioxide, 5-10 pts. wt. nano zirconium oxide, 1-3 pts. wt. modified graphene oxide prepared by modifying using a dispersant, 5-10 pts. wt. nano ytterbium nitrate, 5-10 pts. wt. pigment, 5-10 pts. wt. film-forming additive, 0.1-0.3 pt. wt. antifoaming agent, 3-7 pts. wt. leveling agent and 100-120 pts. wt. water. USE - Nano heat-insulating and temperature-reducing coating for building. ADVANTAGE - The coating has high heat reflectivity of 90%, tensile strength of 2.4 MPa, excellent UV aging resistance, high hardness, glossiness, corrosion resistance, heat resistance, electrochemical characteristics, dispersibility, large specific surface area, infrared reflection characteristics, shielding effect, the lowest thermal conductivity of 0.04 W/m.k, the highest adhesive force of grade 3, improved heat insulation and temperature reducing effect, and effectively isolates solar radiation heat and heat radiation conduction in the air. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the coating, which involves mixing the above raw materials, and stirring uniformly.
