Problems solved by technology

[0008] However, since the substance of this patent document 1 oxidatively decomposes the organic matter by the photocatalyst, it needs to be handled when it is used in an organic coating, but there is no such description at all.
In addition, it is not considered that the photocatalyst is fixed (fixedly attached) in the hollow body with a common adhesive, and the adhesive is oxidized and decomposed, and it is doubtful whether it can be put into practical use.

Abstract

The application of thermal insulation paint on the surface of buildings is well underway. In addition, when the surface of the building is polluted, the reflectance of light decreases, heat is easily absorbed, and the heat insulation effect decreases. Therefore, it is possible to provide a paint that achieves the goals of pollution prevention and heat insulation, greatly reduces the decomposition of the resin, and is easy to apply. The present invention relates to a paint comprising an organic hollow sphere A having photocatalyst fine particles fixed to its surface by thermal fusion, an organic hollow sphere B having fine particles other than photocatalyst fixed to the surface by the same method, Composed of organic resin, colloidal silicon dioxide and water, wherein the specific gravity of the organic hollow sphere B is greater than that of the organic hollow sphere A.

Description

technical field [0001] The invention relates to an emulsion paint. Background technique [0002] Recently, due to the reduction of air-conditioning costs of buildings and the reduction of carbon dioxide caused by air-conditioning, buildings are increasingly insulated. Since it is difficult to renovate walls and roofs in terms of cost, etc., coating of heat-shielding paints (including paints that selectively reflect infrared rays) on the surfaces is being carried out sufficiently. [0003] As such a heat-shielding paint, a hollow body such as glass or silicone rubber having a low heat transfer coefficient is often mixed. The interior of the hollow body is approximately air or vacuum. In addition, since the hollow body itself is very small (10 to 600 μm), it hardly cracks. [0004] In addition, the roof and wall surfaces of buildings are naturally exposed to outside air, and are mostly polluted by dust and soot. When the surface is polluted, the reflectivity of light decre...
