Description

  The present invention relates to a thermoplastic resin composition. More specifically, it has a good surface appearance and flame retardancy while maintaining a high dielectric constant, and is a thermoplastic resin suitable for electrical / electronic parts, home appliances, automobile-related parts, infrastructure-related parts, housing-related parts, etc. Relates to the composition.

  Recently, the demand for flame retardancy of resin products is increasing, and the flame retardancy is required for the resin composition constituting the resin products. In particular, resin-made electronic parts such as antenna parts and wiring boards may ignite due to a short circuit or the like, and therefore, the resin composition constituting those parts is required to have flame retardancy, and in particular, a minute-thick part. Since fires ignite relatively easily, the demand for flame retardancy is even higher.

  On the other hand, with the widespread use of satellite broadcasting, satellite communication, high-definition television broadcasting, mobile phones, and the like, transmission / reception of high-density information using radio waves has been widely performed, and the frequency of use has been increasing. Furthermore, miniaturization of radio wave transmission / reception antennas and circuit boards has been promoted for the purpose of improving space efficiency, including the improvement of transport efficiency in mobile communication devices such as the global positioning system of navigation systems. ing. An antenna used for high frequencies has a basic structure in which a metal foil such as a copper foil is laminated on an antenna substrate. In order to reduce the size of the antenna, it is necessary to use a material having a high dielectric constant as the antenna substrate. That is, the higher the dielectric constant of the antenna substrate, the shorter the wavelength of radio waves that can be received and transmitted by the antenna, the higher the frequency, and the reception of high frequencies is possible even if the antenna substrate is made smaller.

  As a method for producing a high dielectric resin composition, for example, a method of adding barium titanate to a thermoplastic resin is known (Patent Document 1). Further, as a method for improving flame retardancy, a method using a thermoplastic resin and a fluororesin in combination is known (Patent Document 2). However, there has been a problem that the dielectric constant is lowered when trying to improve flame retardancy by adding a fluororesin to a high dielectric resin composition in which barium titanate is added to a thermoplastic resin.

Specific viscosity (η _SP ) = (t−t ₀ ) / t ₀
[T ₀ is methylene chloride falling seconds, t is sample solution falling seconds]
The viscosity average molecular weight M is calculated from the determined specific viscosity (η _SP ) by the following formula.
η _SP /c=[η]+0.45×[η] ² c (where [η] is the intrinsic viscosity)
[Η] = 1.23 × 10 ⁻⁴ M ^0.83
c = 0.7

  The viscosity average molecular weight of the polycarbonate resin in the thermoplastic resin composition of the present invention is calculated as follows. That is, the composition is mixed with 20 to 30 times its weight of methylene chloride to dissolve the soluble component in the composition. Such soluble matter is collected by Celite filtration. Thereafter, the solvent in the obtained solution is removed. The solid after removal of the solvent is sufficiently dried to obtain a solid component that dissolves in methylene chloride. A specific viscosity at 20 ° C. is determined from a solution obtained by dissolving 0.7 g of the solid in 100 ml of methylene chloride in the same manner as described above, and the viscosity average molecular weight M is calculated from the specific viscosity in the same manner as described above.

[Production of barium titanate 1]
A suspension obtained by adding 720 g of pure water to 130 g of barium chloride dihydrate and 130 g of oxalic acid dihydrate and stirring the mixture at a temperature of 55 ° C. for 0.5 hours was designated as solution A. A solution B was prepared by adding 560 g of pure water to 256 g of a titanium tetrachloride aqueous solution of 15.3% by weight in terms of TiO ₂ and diluting it. Next, solution B was added to solution A over 30 minutes at a reaction temperature of 55 ° C. with stirring, and after the addition, aging was performed for 0.5 hours while continuing stirring. After completion of aging, filtration was performed to recover barium titanyl oxalate. Next, the recovered barium titanyl oxalate was repulped with pure water and allowed to stand at 80 ° C. for 24 hours to obtain a barium titanyl oxalate powder. 20 g of the obtained barium titanyl oxalate powder was charged in an alumina crucible, heated for 5 hours, and calcined at 1050 ° C. for 15 hours to obtain barium titanate. The obtained barium titanate was crushed with a mortar to obtain barium titanate particles [barium titanate 1]. [Barium titanate 1] had an average particle diameter D50 (total 50% obtained from volume frequency particle size distribution measurement by laser diffraction scattering method) of 4 μm.

[Production of barium titanate 2]
Barium titanate particles [barium titanate 2] were obtained by the same production method as barium titanate 1 except that the firing temperature was 1350 ° C. and the firing time was 20 hours. [Barium titanate 2] had an average particle diameter D50 of 12 μm.
