Problems solved by technology

However, the multi-layer coating method has problems in that the size of the glass to be deposited is limited, it is difficult to prepare a film in large quantities on each layer when the film thickness is controlled with high precision, and its economic efficiency is low
However, alkoxysilane has a problem in that it has the effect of limiting the storage stability of coating solutions under alkaline conditions, which makes it difficult to stably produce antireflective coatings

Embodiment 1

[0039] 12.8 g of methanol, 7.9 g of methyl cellosolve, and 0.015 g of acetic acid were mixed together in a jacketed reactor while maintaining the temperature of the jacketed reactor at a temperature of 25° C., and then stirred for 10 minutes to prepare a mixed liquid. Then, 0.05 g of brij-56 (poly(ethylene oxide) nonionic surfactant) and 0.03 mol of polyvinylpyrrolidone (MW: 40,000) were added to the mixture to prepare a surfactant-containing mixture. 2.8 g of tri-tert-butoxide aluminum was added to the mixture and mixed at high speed, and 36 g of isopropanol was mixed with the resulting mixture to prepare an aluminum alkoxide mixture.

[0040] HS-40 (Ludox colloidal silica from Grace) was passed through a cation exchange resin to convert HS-40 to acidic colloidal silica with a pH in the range of about 2-3, and was added at 3 wt. based on the total amount of aluminum alkoxide mixture. %-10wt% was added dropwise to the previously prepared aluminum alkoxide mixture. Then, poly...

Embodiment 2

[0043] This example was carried out in the same manner as in Example 1, except that A(Al(OC3H7)3) was used instead of aluminum tri-tert-butoxide used in Example 1.

Embodiment 3

[0045] Acidic colloidal silica was added to the jacketed reactor as described in Example 1, and the obtained mixture was heated and reacted for 1-10 hours while maintaining the temperature of the jacketed reactor at 50-70° C., then cooled to 30° C. , carry out the sol-gel reaction for 1-3 hours.

Abstract

Provided are an method for producing a coating solution with which glass used for the production of solar collector modules is coated to enhance the optical transmittance, and a coating composition produced by the same. According to the prior art, there is a method of alternately stacking a high refractive index layer and a low refractive index layer on each other, coating a film with a photocatalyst for the anti-reflection of films, or using alkoxysilane having a porous structure, in order to increase the transmission of light. However, the prior-art method has problems in that it is difficult to precisely stack the high and low refractive index layers, the production cost is high, and the storage stability of the coating solution is restricted, which makes it difficult to use the prior-art method. However, the present invention is designed to solve such drawbacks of the prior art, the production method and coating composition may be useful to arrange the inorganic particles with a diameter of several ten nanometers to several hundred nanometers so that the inorganic nanoparticles can have a similar array to the porous structure, thereby improving the mechanical property (for example, hardness) of the filler while enhancing the transmittance of the porous structure.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2009-0120735 filed with the Korean Patent Office on Dec. 7, 2009, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to the production of a coating solution with which glass for the manufacture of solar absorber modules can be coated to increase light transmission. Background technique [0004] The invention relates to the production of a coating solution with which glass for the production of solar absorber modules can be coated to increase the optical transmittance. [0005] When light is incident perpendicularly to glass, some of the incident light is lost through refraction at the air / glass interface. In this case, the refractive loss rate of incident light reaches about 4%. For glass used to cover photovoltaic systems such as photovoltaic cells or solar absorbers, the refractive ind...
