Abstract

The invention discloses a low-emissivity coating with an indoor air purification function and a preparation method thereof, and belongs to the field of preparation of building coatings. The coating consists of the following components in percentage by mass: 5 to 20 percent of waterborne acrylic resin, 20 to 50 percent of waterborne elastic resin, 15 to 60 percent of low-emissivity material, 2 to 10 percent of nano titanium dioxide, 0.6 to 2 percent of aid, 1 to 10 percent of film forming aid and 5 to 10 percent of water. The coating has low emissivity and can play a role in preserving heat by adding the low-emissivity material; and the nano titanium dioxide included in the coating can play a role in photo-catalysis, decompose indoor pollutants and achieve an effect of purifying indoor air. The inner wall coating can achieve an energy-saving effect, and has environment-friendly property at the same time.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a low-emissivity coating with indoor air purification function and a preparation method thereof. Background technique [0002] Nano-titanium dioxide has stable chemical properties, is safe and non-toxic, and has excellent photocatalytic performance. The semiconductor band gap of titanium dioxide is 3.2ev, and the particle size of nano-titanium dioxide is small. The time for free electrons and holes to migrate from the interior of the particles to the surface is greatly shortened, further reducing the probability of free electrons and holes recombining. The continuous accumulation of free electrons and holes will form an electric field in the particle. Under the action of the electric field, the electrons and holes will be further separated and migrate to different positions on the particle surface. The free electrons and holes on the surface of the particles will absorb and...
