Problems solved by technology

[0006] Generally speaking, heat-insulating films or window glass coatings that have the functions of shielding infrared rays and absorbing ultraviolet rays at the same time need to be treated with multiple layers on a substrate to form a composite film. The production process is complicated and expensive.

preparation example Construction

[0028] The preparation method of the silicone resin used in the present invention is not particularly limited, and according to a preferred embodiment of the present invention, the silicone resin is formed by a sol-gel (sol gel) method. The raw material of the sol-gel method is about hundreds of nanometer-sized solid particles (usually inorganic metal salts) suspended in a liquid. In a typical sol-gel method, the reactants undergo a series of hydrolysis reactions and polymerization reactions to form a colloidal suspension, and the substances in it will condense into a new phase-a solution containing solid polymers, which is gel. The properties of the prepared sol-gel are affected by the type of raw material, type and concentration of catalyst, pH value, temperature, content of solvent, and type and concentration of alcohols and salts.

Abstract

The invention provides a coating somposition, comprising a photocatalyst compound and a silicon resin. Based on the gross weight of the composition, the content of the photocatalyst compound is 1-70 weight%. The photocatalyst compound comprises heat insulation material and photocatalyst material. The invention also provides an energy-saving material, comprising a base material and a film disposed on at least one surface of the base material. The film is composed by the coating composition. The energy-saving material has advantages of effectively separating infrared rays; greatly reducing indoor temperature; saving power consumption; providing good super-hydrophilicity and self-cleaning function; achieving effects of sterilization and deodorization due to photocatalyst capable of absorbing ultraviolet rays.

Description

technical field [0001] The invention relates to a coating composition, which can be coated on a base material, so that the surface of the base material has the effect of self-cleaning and heat insulation. The present invention also relates to energy-saving materials having films formed from the coating composition. Background technique [0002] There are many materials on the market that are used to block the thermal effect of infrared rays, such as glass curtain walls of buildings, automobile glass, and thermal insulation paper. In short, the purpose of this type of material is to allow sunlight to pass through and provide light, but it is hoped that it can block the heat source (ie, infrared heat effect) brought by sunlight at the same time. However, taking the current glass with shielding infrared properties as an example, its manufacturing cost is too expensive and the effect is not satisfactory. For example, it is known that an ultra-thin silver film capable of absorb...
