Abstract
Description
A curing type polyorganosiloxane composition, a sealing material, and an optical device including the sealing material.
BACKGROUND ART Light emitting devices such as light emitting diodes (LEDs), organic light emitting diode devices (OLED devices), and photoluminescence devices (PL devices) And various automation devices.
These light emitting devices can display an intrinsic color of a light emitting material such as blue, red, and green in a light emitting portion, and can display a white color by combining light emitting portions that display different colors.
Such a light emitting device generally includes an encapsulant of a packaging or encapsulated structure. The encapsulation material protects the light emitting device from external gas and moisture and can transmit light of various wavelengths emitted from the light emitting device to the outside.
In order to improve the process yield of the LED package maker, it is important to produce a package with good color uniformity because each package on which the silicone encapsulant is applied exists in a similar color coordinate. In addition, if the surface of the silicon-encapsulated LED package becomes irregularly large after the package assembly process or the assembling process, the distribution of the color coordinates of each package may be widened. If the surface stickiness occurs, it may cause problems in the mass production process.
In order to solve the above problems, it is necessary to develop a silicone encapsulant having excellent color uniformity and surface adhesive strength.
One embodiment provides a cured polyorganosiloxane composition having improved color uniformity and reduced surface cohesion after curing.
Another embodiment provides an encapsulant obtained by curing the composition.
Another embodiment provides an optical device comprising the encapsulant.

As described above, a light emitting device such as a light emitting diode (LED), an organic light emitting diode (OLED) device, or a photoluminescence device (PL device) , Red, and green. When a phosphor is mixed with an encapsulant to form a white light device, the phosphor emits blue light emitted from the LED chip to green, yellow, red, and the like And the white light is realized by mixing the lights of various colors. Specifically, a light-emitting device is manufactured by mixing and defoaming a solid phosphor in a liquid encapsulant, applying the mixture to the top of the package to which the LED chip is connected, and curing the applied mixture. The mixture is put on a syringe or the like and coated on an LED chip. The density of the solid phosphor is higher than that of the liquid encapsulant, and due to the fluidity of the liquid encapsulant before curing, the phosphor precipitates in the encapsulating material over time do. Therefore, even if a light emitting device is manufactured using a mixture of the same encapsulant and a fluorescent substance, the concentration of the fluorescent substance in the sealing material below the syringe becomes higher with time, and the resultant light emitting device and the light emitting device There is a difference in the phosphor content. Such a difference in the phosphor content causes a color difference between the elements, and thus the reliability of the encapsulant and the phosphor mixture and the light emitting device manufactured therefrom can not be secured.
In addition, if the irregular roughness of the surface of the silicon-encapsulated LED package becomes large after the package assembly process or the completion of assembly, the distribution of the color coordinates of each package may be widened, and if the surface stickiness occurs, it may cause problems in the mass production process. In order to solve these problems, it has become necessary to develop a silicone encapsulant having excellent color uniformity and surface adhesion.
Previously, attempts were made to improve the color uniformity by increasing the viscosity of the encapsulant and controlling the reaction rate, but this did not lead to a significant improvement in the process yield. For example, in order to improve color dispersion, there is a technique of increasing the dispersibility of a phosphor by mixing an inorganic filler such as alumina (Al 2 O 3 ) or silica (SiO 2 ) to increase the viscosity of the encapsulant, The specific gravity is about 3.7, which is much larger than the silicone composition having a specific gravity of 1.1. Therefore, it is troublesome to use a dispersing aid to uniformly disperse these inorganic fillers in the composition. In addition, the dispersion auxiliary agent has a problem that discoloration rapidly occurs when exposed to heat, and deteriorates.
On the other hand, when the surface sticking (sticking) of the cured encapsulating material occurs, the progress of the mass production process may be stopped and the production operation rate may be lowered. Thus, when the surface sticking force is effectively reduced, excellent mass production feasibility can be obtained. In addition, in order to improve the process yield, it is important that each package separately exists in a similar color coordinate when the package is produced. That is, the process yield can be improved by increasing the color uniformity.
As a result of intensive studies, the inventors of the present invention have developed a technique of uniformly dispersing a phosphor (specific gravity: about 2.7 to 4.5) having a specific gravity as compared with a silicon encapsulant using an organic filler instead of an inorganic filler. Includes the step of including a polyalkylene oxide-based organic compound, which is hydrophilic, in a conventional silicone encapsulating material composition in a certain amount relative to the silicone encapsulating material composition content. That is, the polysiloxane composition constituting the composition for the silicone encapsulant exhibits hydrophobic properties while the phosphor exhibits hydrophilicity, and it is preferable that the polyalkylene oxide-based organic compound exhibiting hydrophilicity has a constant By weight, the hydrophilic phosphors are more uniformly dispersed in the composition. As a result, the color dispersion after curing of the composition becomes narrow, and the surface adhesion of the silicone sealing material produced by the effect of the density difference with the composition is reduced. As described above, the sealant composition in which the surface adhesive force is reduced after curing can remarkably improve the processability.
As described above, in the above embodiment, by adding 0.05 to 3% by weight, for example, about 0.1 to 1.0% by weight, of the hydrophilic polyalkylene oxide-based organic compound to the total weight of the polysiloxane composition, Thereby inducing uniform dispersion of the hydrophilic fluorescent substance contained therein and improving the color uniformity of the resulting composition after curing.
By including the hydrophilic polyalkylene oxide-based organic compound in the above-mentioned content range, the color dispersion of the LED package including the encapsulant produced therefrom can be achieved by using the LED package including the sealing material not containing the hydrophilic polyalkylene oxide- For example, about 45% or more, such as about 50% or more, such as about 55% or more, such as about 60% or more, for example, about 30% . For example, when the color dispersion of the LED package including the encapsulating material containing no hydrophilic polyalkylene oxide organic compound is 100%, the hydrophilic polyalkylene oxide based organic compound may be added in an amount of about 0.1 The color dispersion of an LED package comprising an encapsulant comprising in the range of about 1% to about 40% by weight can be reduced by about 60%, such as about 55%, such as about 45%, e.g., about 40%. That is, when several tens to several hundred LED packages are manufactured using the same encapsulant composition, and the length of the color distribution represented by the x, y color coordinates on the CIE 1931 color space of each package is measured and displayed using an integrating sphere , And the length of the color distribution of the package including the encapsulating material not containing the polyalkylene oxide based organic compound is 100%, the color of the package including the encapsulating material containing the polyalkylene oxide based organic compound The length of the distribution may be up to 70%, such as up to about 65%, such as up to about 60%, such as up to about 55%, such as up to about 50%, for example up to about 45% For example, about 40% or less.
In addition, when the hydrophilic polyalkylene oxide-based organic compound of Formula 1 is contained in the above-mentioned content range, the surface adhesion of the cured encapsulant is also significantly reduced. For example, when the hydrophilic polyalkylene oxide-based organic compound is included in the above-mentioned content range, the adhesive strength of the encapsulating material may be about 30% or more, for example, about 40% or more, for example about 50% Or more, for example, by 55% or more. For example, the surface adhesion after curing of the composition may be less than 40 gf (gram force), for example less than or equal to about 35 gf, such as less than or equal to about 30 gf, such as less than or equal to about 25 gf. This reduction in surface adhesion can significantly improve the fairness of the LED package.
The basic siloxane compound constituting the curable polyorganosiloxane composition according to the above embodiment may be any as long as it is used in the art to form a curable polyorganosiloxane.
For example, at least one first siloxane compound having (A) a silicon-bonded alkenyl group (Si-Vi) may be represented by the following formula (2).

After completion of the dropwise addition, condensation polymerization reaction was carried out while refluxing at 90 ° C for 3 hours. After cooling to room temperature, the water layer was removed to prepare a polymer solution dissolved in toluene. The resulting polymer solution was washed with water to remove chlorine as a by-product of the reaction. Subsequently, the neutral polymer solution was distilled under reduced pressure to remove toluene to obtain a first siloxane compound represented by the following formula (4).

(2) a phosphor containing Encapsulant The preparation of the composition and LED Manufacturing of packages
The curable polyorganosiloxane composition prepared above was mixed with a red phosphor and a green phosphor in a ratio of 1:10 by 20% by weight based on the total weight of each composition, and then the mixture was evacuated and defoamed, , And the sealant composition of Comparative Example 1 were prepared.
Each of the encapsulant compositions prepared above was applied to a mold (2.5 cm (width) x 7.5 cm (length) x 1 cm (thickness)) coated with a dispenser and Teflon on an LED package and cured at a high temperature. The curing was carried out in order to prevent shrinkage of the silicone resin. The curing condition was maintained at 120 캜 for 30 minutes, then increased to 170 캜 and maintained for 2 hours to cure the encapsulant composition. The sealant composition may be applied on a coated mold by filling the mold with a reflector by discharging the composition using a 20 ml syringe. When the discharged composition hardens, the LED package is completed.
(Shorea)
In the above table, the contents of components (A) to (C-3) are all% by weight.
The refractive index was measured before the curing of the liquid composition under the D-line (589 nm) wavelength using an Abbe refractive index meter.
The surface of the cured specimen was measured using an adhesion tester (TopTac 2000, manufactured by Soften corporation).
The color scattering percentage (%) is a value indicating the length of a distribution expressed by x, y color coordinates on a CIE 1931 color space in a range of 150 to 200 packages that can be discharged from a 20 ml syringe at the time of luminance measurement. At this time, the value of Comparative Example 1 was set to 100%, and the lengths of the color distributions of Examples 1 to 6 were relatively shown. The smaller the length of the color distribution, the smaller the color dispersion (%), which means that the color uniformity is high. Each optical element measures its color coordinates using spectroradiometers, and expresses the respective values as x, y color coordinates to quantify the lengths of the minimum and maximum values of x, y as a percentage.
FIG. 2 is a graph showing the results of the evaluation of the optical characteristics of the optical devices by applying red and green phosphors to the encapsulating material composition according to Comparative Example 1 by applying the red and green phosphors in 150 to 200 packages, It is represented by x, y color coordinates on the 1931 color space.
FIGS. 3 to 5 are diagrams illustrating a method for manufacturing a light emitting device according to the present invention, in which red and green phosphors are added to the encapsulating material composition according to Examples 1 to 3, respectively, and applied to 150 to 200 packages, And is represented by x, y color coordinates on a CIE 1931 color space using a spectroradiometer.
As can be seen from the above Table 1, the polyorganosiloxane composition containing the polyalkylene oxide compound of Formula 1 according to this embodiment, when used, does not contain the color uniformity in manufacturing the light emitting device And surface adhesion decreased by more than 50%.
As described above, the curable polyorganosiloxane composition according to the embodiment of the present invention can induce uniform dispersion of the phosphor when the optical element is manufactured by including the phosphor, thereby making it possible to manufacture the light emitting element having no color difference between the elements And the surface adhesive force of the encapsulant produced therefrom is also reduced, so that the reliability and fairness of the light emitting device can be greatly improved.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, And falls within the scope of the invention.
