Description

[Technical Field] The present invention relates to a resin composition in which a boron nitride nanotube is dispersed in a thermoplastic resin, a method for producing the same, and a molded article thereof. [Prior Art] Carbon nanotubes have become an eye-catching nanotechnology because they have mechanical properties, electrical properties, and thermal properties that were not previously available. Therefore, they have been reviewed for their application in a wide range of fields and have been partially put into practical use. Further, attempts have been made to add a carbon nanotube for use in a resin to improve the mechanical properties, electrical conductivity, heat resistance and the like of the resin. For example, a carbon nanotube obtained by surface modification with a chemical bond is used to enhance the mechanical properties of polycarbonate (Patent Document 1). In addition, the carbon nanotubes coated with the conjugated polymer can extremely improve the dispersibility of the carbon nanotubes, so that a small amount of carbon nanotubes can be used to impart high conductivity to the matrix resin (Patent Document 2). Further, in the case of a polymer composite material having a polymethyl methacrylate or polystyrene acid branched structure polymer and a carbon nanotube, when a single layer carbon nanotube is coated with a conjugated polymer 'A report that the elastic modulus can be increased by a factor of a single layer of carbon nanotubes (Patent Documents 3 and 4). Further, a boron nitride carbon nanotube having a similar structure to that of a carbon nanotube has also become a material having a previously unknown property (Patent Document 5). It is known that boron nitride nanotubes not only have excellent mechanical properties and thermal conductivity comparable to those of carbon nanotubes, but also have better chemical stability than carbon nanotubes -5 - 200846403. In addition, it is also an insulating heat-releasing material that is expected to be insulative. [Patent Document 1] Japanese Laid-Open Patent Publication No. JP-A No. 2004-2621 [Explanation] [Explanation of the Invention] It is an object of the invention to provide a resin composition which can form a molded body excellent in thermal conductivity. SUMMARY OF THE INVENTION An object of the present invention is to provide a molded body excellent in thermal conductivity. An object of the present invention is to provide a method for producing the resin composition. In recent years, electronic molded parts have been widely used in electronic devices. Electronic machines emit heat, so their parts are required to be exothermic, ie thermally conductive. In order to impart thermal conductivity to the resin, inorganic oxide particles such as cerium oxide or aluminum oxide are added to the resin. However, the inorganic particles have a large particle size, so that the amount of heat conductivity is increased, and a large amount of the alloy may impair the original mechanical strength of the resin. Therefore, the inventors of the present invention examined the dispersibility of a boron nitride nanotube in a resin in a method of maintaining thermal conductivity under the original mechanical strength of the resin. As a result, it has been found that polyimine can effectively disperse the boron nitride nanotubes to obtain a resin composition having excellent mechanical strength and heat resistance, but there is no expectation in improving thermal conductivity. In the case of polycarbonate, polyester, acrylic resin and other thermoplastic resins having a solubility of -6 - 200846403 (δ), the dispersion of boron nitride nanotubes is inferior to that of polyamine, but it can significantly improve heat conduction. The present invention was completed. Further, the resin composition in which the boron nitride nanotube is dispersed in the thermoplastic resin can have excellent mechanical strength and dimensional stability. . That is, the present invention is a resin composition containing 100 parts by weight of a thermoplastic resin having a solubility parameter (δ) of 9 to 12 and 0.01 to 100 parts by weight of a boron nitride nanotube. Further, the present invention is a method for producing a resin composition of a boron nitride nanotube and a thermoplastic resin having a solubility parameter (3) of 9 to 12. Further, the present invention is a molded body formed by the above resin composition. BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below. <Resin composition> (boron nitride nanotube) The boron nitride nanotube of the present invention is a tube-like material formed of boron nitride, which is a 6-corner mesh surface having an ideal structure.

The average diameter and average aspect ratio of the boron nitride nanotubes can be determined by electron microscopy. For example, when measuring by a 透光 (transmission electron microscope), the diameter of the boron nitride nanotube and the length in the longitudinal direction can be directly measured from the screen. Further, the form of the boron nitride nanotube in the composition can be obtained, for example, by measuring the cross section of the fiber parallel to the fiber axis (transmission electron microscope). The average diameter and the average length of the present invention are determined by arithmetical averaging of any of the 50 images on the electron microscope. It is known that a boron nitride nanotube can be synthesized by an arc discharge method, a laser heating method, or a chemical vapor phase growth method. Further, it can be synthesized by a known method using a nickel boride catalyst and a borazine as a raw material. Alternatively, it can be synthesized by a method in which a carbon nanotube is proposed as a mold to react boron oxide with nitrogen.
