Nano-insulation reflective paint

Abstract

The invention discloses a nano-insulation reflective paint, which comprises a nano-inorganic material, a film forming substance, hollow glass microspheres, inorganic nano-particles, and additive and a proper amount of water. According to the nano-insulation reflective paint, the nano-inorganic material, the inorganic nano-particles and the hollow glass microspheres are mixed to form a gas layer which has a heat blocking effect and can reflect solar heat as much as possible; the pH value of solution, which is adjusted by using an electro-chemical method, differs from that of an isoelectric point maximally, so that a similar double electrode layer structure is formed at the interface of the nano-particles, so that the dispersibility and stability of the inorganic nano-particles and hollow microspheres are solved; and the manufactured paint film can save energy by about 35 percent.

Description

technical field [0001] The invention relates to a nano heat-insulating reflective paint. technical background [0002] At present, improving the effect of thermal insulation coatings and avoiding fires is a hot topic in the construction industry and coating manufacturing industry. [0003] In the published patent literature, there are some thermal insulation coatings, Sb-doped SnO 2 , (ATO), due to the influence of its own carrier concentration and other factors, makes its plasma cut-off frequency in the near-infrared region, so it has a good reflection and absorption effect on the radiation in the near-infrared region, but the Sb contained in ATO Elements are heavy metal elements with certain toxicity. while Sn-doped In 2 o 3 (ITO) has a fairly high infrared blocking effect and high transparency of visible light, but the In element is a precious metal element, and its storage capacity on the earth is very limited, and the use of the In element also increases the cost of...

Problems solved by technology

[0003] In the published patent literature, there are some thermal insulation coatings, Sb-doped SnO 2 , (ATO), due to the influence of its own carrier concentration and other factors, makes its plasma cut-off frequency in the near-infrared region, so it has a good reflection and absorption effect on the radiation in the near-infrared region, but the Sb contained in ATO Elements are heavy metal elements with certain toxicity

while Sn-doped In 2 o 3 (ITO) has a fairly high infrared blocking effect and high transparency of visible light, but the In element is a precious metal element, and its storage capacity on the earth is very limited, and the use of the In element also increases the cost of raw materials, resulting in inability to widely used
