摘要

PURPOSE: A manufacturing method of a finishing material is provided to improve durability of exterior by constructing the finishing material with water resistance, staining resistance, and weatherability. CONSTITUTION: A manufacturing method of a finishing material comprises 25-35 parts by weight of calcium carbonate, 7-9 parts by weight of adhesive, 0.5-1.0 parts by weight of ammonia, 0.5-1.0 parts by weight of preservative, 5-7 parts by weight of mica, and 15-18 parts by weight of silica to obtain a mixture A; a step of mixing and stirring 5-8 parts by weight of a photocatalyst, 5-8 parts by weight of UV absorbent, 0.5-5 parts by weight of water repellent, and 20-30 parts by weight of porous ceramic; a step of removing filtrate from the mixture and drying the same to obtain a mixture B; a step of uniformly mixing the mixture A and mixture B. The heat treatment is conducted for 30 minutes at 40-60 =.
