Benefits of technology

The present invention provides a coating composition that includes a photocatalyst composite and a silicone resin. The photocatalyst composite contains a heat insulation material and a photocatalyst material. The coating composition effectively insulates or reflects heat-causing infrared light and has self-cleaning, antifog, antimicrobial, and deodorization effects. The coating composition can be applied on a substrate through a common coating method, and the preparation process is relatively simple and cheap. The energy-saving material formed from the coating composition has self-cleaning and heat insulation effects.

Problems solved by technology

However, with an existing glass having the infrared light shielding property as an example, the production cost is too high and the effect is less satisfactory.
For example, it is known that an ultra thin infrared light absorption silver film may be embedded in the glass to shield the infrared light; however, the preparation cost is high, and silver is easily oxidized, and thus loses the infrared light shielding effect.
However, the film thus formed has the following disadvantages of high cost, complex manufacturing process, and unsatisfactory effect, thus not meeting the requirement of economic benefits.
However, upon irradiation with intense sunlight or scattered light, a fume like haze occurs to this kind of glass containing pigment or dye, and thus the infrared light absorbing performance is influenced, and the pigment or dye will be decomposed after long time of use and lose the corresponding effects.
Generally, as for a heat insulation film or window glass coating having the infrared light shielding and UV light absorbing functions, multi-layer processing is required to be performed on a substrate, to form a composite film, the preparation process is complex, and the preparation cost is high.

Abstract

A coating composition comprising a photocatalyst composite and a silicone resin is provided, in which the content of the photocatalyst composite ranges from about 1% to about 70% by weight (wt %), based on the total weight of the coating composition, and the photocatalyst composite contains a heat insulation material and a photocatalyst material. An energy-saving material is further provided, which includes a substrate and a film formed from the coating composition of the present invention on at least one of the surfaces of the substrate. The energy-saving material is capable of effectively shielding off infrared (IR) light, substantially decreasing indoor temperature, and reducing power consumption. In addition, in the presence of the photocatalyst which can absorb ultraviolet light, the material also exhibits good superhydrophilic and self-cleaning properties and provides antimicrobial and deodorization effects.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a coating composition, which can be coated on a substrate, so as to enable the surface of the substrate to have self-cleaning and heat insulation effects. The present invention further relates to an energy-saving material containing a film formed from the coating composition of the present invention.[0003]2. Description of the Prior Art[0004]There are many materials for shielding the heat effect of infrared light available in the market, for example, glass curtain of a building, automobile glass, and heat insulation paper. In short, the materials are provided for the purpose of allowing the sunlight to pass through to provide light, while the heat source (that is, heat effect of infrared light) is expected to be insulated. However, with an existing glass having the infrared light shielding property as an example, the production cost is too high and the effect is less satisfactory. For ex...
