Water-based environment-friendly nanometer negative ion smoke-decomposing coating and preparation method thereof

Abstract

The invention discloses a water-based environment-friendly nanometer negative ion smoke-decomposing coating and a preparation method thereof. The coating comprises, by mass, 15% to 20% of a water-based negative ion emulsion, 10% to 20% of a water-based elastic silicon-acrylic emulsion, 1% to 2% of a water-based dispersant, 20% to 25% of calcium carbonate, 10% to 15% of titanium dioxide, 5% to 10% of kaolin, 0.5% to 1% of an anti-freezing agent, 2% to 5% of a thickening agent, 0.5% to 1% of an antifoaming agent, 0.2% to 0.5% of an antibacterial agent, 0.2% to 0.5% of a mildew inhibitor, 1% to 3% of an antifouling agent, 0.1% to 0.5% of a neutralizing agent, 5% to 8% of a film-forming aid and 10% to 15% of deionized water. The coating provided in embodiments in the invention is used for coating building matrixes and concrete structures to realize effective air-tight, corrosion-resistant, scrape-resistant, acid-resistant, alkali-resistant and impact-resistant protection of the building matrixes and concrete structures, can also release negative ions, inhibit bacteria and mildew, decompose smog, purify air and rapidly remove and degrade harmful gas and indoor peculiar smell, and has long-lasting effect.

Description

technical field [0001] The invention relates to the technical field of water-based functional building materials, in particular to a water-based environment-friendly nano-anion decomposable smog paint and a preparation method thereof. Background technique [0002] 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 protective coating of many construction projects has become an important topic in the construction engineering field. 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. Architectural coatings endow the building substrate with a brand new surface. On the one hand, it can effect...
