201107413 VI. Description of invention:

The present invention relates to a resin composition of a polycarbonate resin and an inorganic material having infrared shielding properties, and a molded article comprising the resin composition. [Previous 3 Background] Since the human body feels hot when light having an infrared ray area contacts the skin of the human body, it is necessary to use a window assembly for an automobile or a building component to largely block the light in the infrared wavelength region. At the same time, it is preferred to ensure the field of view by transmitting the wavelength of the visible light region as much as possible in the window assembly. In other words, by using a material that shields infrared rays and transmits visible light, it is possible to reduce the body temperature and to manufacture a window member that can reduce the energy consumption of air conditioners and the like. In addition, in recent years, due to the environmental concerns or the improvement of technology, energy-saving and space-saving are progressing, and various types of infrared shielding materials are required, which have shielding properties in specific wavelength regions. Thick sheets or injection molded articles are becoming very practical. Patent Document 1 ' discloses a resin composition obtained by using an organic infrared shielding material as a material having a low haze. However, since the organic infrared shielding material is thermally unstable, it is difficult to form the molding system in the usual molding temperature zone of the polycarbonate resin. In addition, as in the case of the patent document 2 and the patent document 3, an inorganic infrared shielding material such as ATO or ITO is used, but the turbidity is likely to be high. Moreover, the infrared shielding material is required to be raised to a higher light shielding property when the sunlight reaches the ground and the human body feels the temperature feeling high from the near-infrared wavelength region to the mid-infrared wavelength region. In order to improve this, a tungsten-based inorganic additive is studied, for example, in Patent Document 4 or Patent Document 5'. However, the polycarbonate resin containing an infrared shielding material is known to have an environmental factor such as outdoor exposure, moist heat, etc., and the performance of shielding infrared rays or transmitting visible light is lowered to be required to improve performance.

(Production of Resin Composition) When the resin composition of the present invention is produced, the production method thereof is not particularly limited. However, the resin composition of the present invention is preferably produced by melt-kneading each component. Specific examples of the kneading method include a Schelling mixer, a kneading roll, an extruder, etc. Among them, in terms of kneading efficiency, an extruder is preferred, and a multi-axis extrusion such as a twin-screw extruder is used. Preferably, the press is as follows. The preferred embodiment of the twin-screw extruder is as follows. The shape of the screw can be made of purlins, two and three threaded screws, especially the handling ability or shearing of the refining resin. A wide range of two threaded screw systems suitable for both sides of the mixing capacity can be used. The ratio of the length (6) to the diameter (D) of the screw in the twin-screw extruder is preferably from 20 to 45. 28 to 42 is more preferable. It is easy to achieve uniform dispersion in the case of L/D, but when it is too large, the valley is liable to cause decomposition of the resin due to thermal deterioration. In order to improve the kneading screw, there is one or more kneading segments ( Or the kneading zone formed by the section of the phase thereof is necessary, and preferably has 丨~3. Moreover, as an extruder, it is capable of generating moisture from the raw material or from the melt-kneaded resin. The exhaust hole of the volatile gas degassing can be suitably used. In order to efficiently generate the generated moisture or volatile gas The vent hole is discharged to the outside of the extruder to set the vacuum pump. Further, in order to remove the foreign matter in the extruded raw material, the section before the extrusion die of the extruder may be set 21 201107413 Such a mesh screen may be a wire mesh, a mesh screen exchanger, a sintered metal plate (a disk filter, etc.), etc. Further, a component B or a component C and other additives (hereinafter simply referred to as "additives") are supplied. The method to the extruder is not particularly limited, and the following methods can be exemplified: (1) a method of separately supplying an additive to a polycarbonate resin to an extruder; (ii) using a high-speed stirrer such as an additive and a polycarbonate resin; a method of supplying to an extruder after premixing of the mixer; and (iii) a method of premixing and melting the additive with the polycarbonate resin and granulating the mother. One of the above methods (ii) is a method in which all necessary raw materials are premixed and supplied to an extruder. In another method, a mother agent obtained by blending a high concentration of an additive is prepared, and the mother agent is further preliminarily kneaded with the remaining polycarbonate resin or the like, and then supplied to an extruder. Further, the mother agent may be in the form of a powder form or a form obtained by compressing and granulating the powder. In addition, other premixing methods include a Nauta mixer, a V-type blender, a Schneider mixer, a mechanochemical device, an extrusion mixer such as an extrusion mixer, etc., and a mixer such as a high-speed agitator is preferred. . Further, another method of premixing is, for example, a method of removing the solvent after the polycarbonate resin and the additive are uniformly dispersed in a solvent. The resin extruded using the twin-screw extruder was directly cut and pelletized, or after the strands were formed, the strands were cut and pelletized using a granulator. Further, when it is necessary to reduce the influence of external dust or the like during granulation, it is preferable to purify the environment around the extruder. (Molded product) As the resin composition of the present invention obtained as described above, generally, the pellets produced as described above can be produced by injection molding into a variety of molded articles. In this injection molding, not only the usual molding method, but also injection molding, injection molding, gas-assisted molding, foam molding (including injection of supercritical fluid), insert molding, and molding can be used according to the purpose. A molded article is obtained by an injection molding method such as inner coating molding, heat insulating mold molding, rapid heating and cooling mold molding, two-color molding, inflammatory layer structure molding, and ultrahigh-speed injection molding. The advantages of these various forming methods are widely known. Further, the shape can select either the cold runner method or the hot runner method. Further, the resin composition of the present invention can also be used in the form of various shaped extruded articles, sheets, films, and the like by extrusion molding. Further, a blow molding method, a calendering method, a casting method, or the like can be used for forming the sheet and the film. Moreover, it is also possible to form a heat shrinkable tube by performing a specific stretching operation. Further, the resin composition of the present invention can also be formed into a hollow molded article by spin molding or blow molding. According to the above-described molding process, it is possible to obtain a molded article which is excellent in transparency and excellent in pattern design despite having an infrared shielding ability. The molded article of the present invention has a visible light transmittance of 50% to 85% and a value of Tts (1% of total total transmittance) of 60% or less. Further, the visible light transmittance is in the range of 60% to 85%, and the value of Tts (solar total transmittance; Solar total transmission) is preferably 60% or less, and the visible light transmittance is in the range of 65% to 85%. A value of Tts (total total transmittance; Solar total transmission) of 60% or less is more preferable. When the visible light transmittance is less than 50%, the visibility is deteriorated. When the visible light transmittance is higher than 85%, the increase in Tts becomes difficult because a large amount of energy is transmitted in the visible light region. 23 201107413 Also, when Tts is at 60% south, the shielding ability of the hotline will become insufficient. Further, in the molded article composed of the resin composition of the present invention, various surface treatments can be performed. The surface treatment referred to herein is a resin molded article such as vapor deposition (physical vapor deposition, chemical vapor deposition, etc.), plating (electroplating, electroless plating, and hot-dip plating), coating, coating, printing, or the like. A new layer is formed on the surface layer, and the method generally used for polycarbonate resin can be applied. Specific examples of the surface treatment include various surface treatments such as hard coating, water repellent coating, oil repellent coating, ultraviolet absorbing coating, infrared absorbing coating, and metal coating (represented by vapor deposition). Hard coating is particularly preferred and is generally considered to be necessary surface treatment. By performing the surface treatment, it is possible to further impart performance such as pattern designability and weatherability to the molded article.
