NOVELTY - A breeding shed comprises breeding house, an external coating, an internal coating, and a water supply device. The external coating is formed by coating the external paint on the outside of the breeding house component by airless spraying, roller coating, and brushing methods. The internal coating is formed by coating the internal paint on the inside of the breeding house component by airless spraying, roller coating, and brushing methods. The external paint contains 0.8-1.5 pts. wt. pH regulator, 15-20 pts. wt. solvent, 5-8 pts. wt. insulation additive, 4-7 pts. wt. silicon nanoadditive, and 2-4 pts. wt. additive. The internal coating comprises a component (A) and a component (B) in weight ratio of (7-9):(11-15). The component (A) comprises 60-80 pts. wt. hexamethylene diisocyanate trimer, and 20-40 pts. wt. modified ester additive. The component (B) contains 40-50 pts. wt. polyasparate resin, 15-20 pts. wt. modified ester additive, and 7-10 pts. wt. pigment. USE - Breeding shed used for breeding livestock and poultry e.g. pig, sheep, rabbit, duck, chicken, cattle, buffalo, and goose (all claimed). ADVANTAGE - The breeding shed has excellent corrosion resistance, wear resistance, and heat insulation property, solar reflectance of 0.86 or more, hemispherical emissivity of 0.88 or more, and is easy to clean. DETAILED DESCRIPTION - A breeding shed comprises breeding house, an external coating, an internal coating, and a water supply device. The external coating is formed by coating the external paint on the outside of the breeding house component by airless spraying, roller coating, and brushing methods. The internal coating is formed by coating the internal paint on the inside of the breeding house component by airless spraying, roller coating, and brushing methods. The external paint comprises 75-85 pts. wt. D906 hyperbranched resin, 0.8-1.5 pts. wt. pH regulator, 15-20 pts. wt. solvent, 5-8 pts. wt. insulation additive, 4-7 pts. wt. silicon nanoadditive, 0.3-0.6 pt. wt. preservative, and 2-4 pts. wt. additive. The internal coating comprises a component (A) and a component (B) in weight ratio of (7-9):(11-15). The component (A) comprises 60-80 pts. wt. hexamethylene diisocyanate trimer and 20-40 pts. wt. modified ester additive. The component (B) comprises 40-50 pts. wt. polyasparate resin, 15-20 pts. wt. modified ester additive, 7-10 pts. wt. pigment, 8-12 pts. wt. inorganic additive, 0.5-0.8 pts. wt. dispersant, 1-1.5 pts. wt. leveling agent, and 0.8-1 pt. wt. defoamer.
