Long-acting high-weather-resistant self-cleaning aqueous multicolor coating material and preparation method thereof

Abstract

The invention discloses a long-acting high-weather-resistant self-cleaning aqueous multicolor coating material, which comprises a component A and a component B, wherein the component A comprises: 35-50% of aqueous fluorocarbon emulsion, 5-10%of aqueous silicone acrylic emulsion, 5-10% of aqueous polyurethane emulsion, 10-15% of an aqueous protection glue solution, 1-2% of a pigment, 3-5% of a lead-free filler, 1-2% of an aqueous nanometer hydrophobic agent, 0.1-0.3% of a light stabilizer, 0.5-1% of an anti-freezing agent, 0.5-1% of a thixotropic agent, 15-20% of deionized water and other aqueous auxiliary agents, and the component B comprises: 40-60% of aqueous fluorocarbon emulsion, 10-15% of aqueous silicone acrylic emulsion, 5-10% of aqueous polyurethane emulsion, 1-3% of an aqueous nanometer hydrophobic agent, 0.1-0.3% of a light stabilizer, 0.2-0.5% of an anti-freezing agent, 0.2-0.5% of a thixotropic agent, 25-35% of deionized water and other aqueous auxiliary agents. The prepared coating material of the invention is good in weather resistance and excellent in self-cleaning property.

Description

[0001] Technical field [0002] The invention relates to the technical field of functional building materials, in particular to a long-acting high weather resistance self-cleaning water-based multi-color paint and a preparation method thereof. Background technique [0003] With the rapid development of the national economy and the expansion of the scale of infrastructure construction, the rapid development of the construction industry has been promoted. At the same time, the aging of protective coatings in many construction projects has become an important issue in the construction industry. The variety and quality level of building materials restrict the building and structural form and construction methods, and directly affect the safety, reliability, durability and applicability (economical, beautiful, energy-saving) and other performances of civil and construction projects. [0004] Architectural coatings give the building matrix a brand-new surface. On the one hand, it ca...
