Abstract
The invention provides an anti-sagging thermal-insulation self-cleaning coating for a building external wall and a preparation method thereof. The coating comprises the following components in parts by weight: 50-100 parts of silicone acrylic emulsion, 40-60 parts of elastic emulsion, 5-20 parts of polyacrylamide, 6-15 parts of prefabricated fiber coating material, 4-10 parts of sodium humate, 3-5parts of expanded vermiculite, 10-22 parts of filler, 1-5 parts of auxiliary agent and 10-30 parts of water. The raw materials are selected and proportioned reasonably and the leveling property and the sagging resistance of the coating are effectively balanced; meanwhile, the coating has excellent waterproof, dustproof, heat preservation, weather resistance, ultraviolet resistance and other properties and the mechanical property is also obviously improved; in addition, the coating has excellent adhesion and film-forming properties, the coating stability is high, stripping resistance and cracking resistance are high, the comprehensive efficiency improvement degree is high the effective service life is prolonged by 3-5 times and the coating is worthy of popularization and application.
