Description
Technical Field
The present invention relates to a thermoplastic resin composition for laser direct structuring and a molded article comprising the same. More particularly, the present invention relates to a thermoplastic resin composition for laser direct structuring, which exhibits good characteristics in terms of plating reliability, impact resistance, flowability, and the like, and a molded article including the same.
Background
A Laser Direct Structuring (LDS) process may be used to form a metal layer on at least a portion of the surface of a molded article produced from the thermoplastic resin composition. The LDS process refers to a process of modifying a plating target area on the surface of a molded article to have characteristics suitable for plating by irradiating the plating target area with a laser beam. For this reason, the thermoplastic resin composition needs to contain an additive for laser direct structuring (LDS additive) which can form a metal core upon irradiation with a laser beam. The LDS additive is decomposed to produce a metal core. Further, the area irradiated with the laser beam has a rough surface. Due to this metal core and surface roughness, the laser modified region becomes suitable for electroplating.
The LDS process allows for rapid and economical formation of electronic/circuitry on three-dimensional molded articles. For example, the LDS process may be advantageously used to manufacture antennas for portable electronic devices, Radio Frequency Identification (RFID) antennas, and the like.
In recent years, with an increase in the trend of weight and thickness reduction of portable equipment devices, there has been an increasing demand for thermoplastic resin compositions that can exhibit excellent mechanical properties and molding processability (flowability). Further, as the thickness of a fine pattern (plating area) of an electric/electronic circuit such as a portable electronic device or the like becomes thinner, there may be a problem that plating reliability is deteriorated due to plating peeling.
Therefore, there is a need to develop a thermoplastic resin composition for laser direct structuring, which exhibits good properties in terms of plating reliability, impact resistance, flowability, and the like, and a molded article including the same.
Background art of the present invention is disclosed in korean patent laid-open publication No. 2011-0018319 and the like.

In some embodiments, the diol-modified polyester resin may be present in an amount of about 5 parts by weight to about 55 parts by weight, for example, about 5 parts by weight to about 50 parts by weight, relative to about 100 parts by weight of the polycarbonate resin. If the content of the diol-modified polyester resin is less than about 5 parts by weight relative to about 100 parts by weight of the polycarbonate resin, the thermoplastic resin composition may suffer from deterioration in plating reliability and the like, and if the content of the diol-modified polyester resin exceeds about 55 parts by weight, the thermoplastic resin composition may suffer from deterioration in plating reliability and the like.
(C) Additive for laser direct structuring
According to the present invention, the LDS additive is used to form a metal core upon irradiation with a laser beam, and may include any LDS additive used in a typical resin composition for LDS. Here, the laser beam means light amplified by simulated emission (simulated emission light), and may be UV light having a wavelength of about 100nm to about 400nm, visible light having a wavelength of about 400nm to about 800nm, or Infrared (IR) light having a wavelength of about 800nm to about 25,000nm, for example, IR light having a wavelength of about 1,000nm to about 2,000 nm.
In some embodiments, the LDS additive may include a heavy metal composite oxide spinel and/or a copper salt.
In some embodiments, the heavy metal composite oxide spinel may be represented by formula 1.
AB2O4
In formula 1, a is a metal cation having a valence of 2, for example, magnesium, copper, cobalt, zinc, tin, iron, manganese, nickel, and a combination thereof, and B is a metal cation having a valence of 3, for example, manganese, nickel, copper, cobalt, tin, titanium, iron, aluminum, chromium, and a combination thereof.
In the heavy metal composite oxide spinel represented by formula 1, a provides a monovalent cation component of the metal oxide cluster and B provides a monovalent cation component of the metal cation cluster. For example, the metal oxide cluster including a may have a tetrahedral structure and the metal oxide cluster including B may have an octahedral structure. Specifically, the heavy metal composite oxide spinel represented by formula 1 may have a structure in which: wherein the oxygen atoms are arranged in a cubic close-packed lattice and B and a occupy octahedral and tetrahedral sites in the lattice, respectively.

Copper hydroxide phosphate is a compound in which copper phosphate is combined with copper hydroxide, and may include Cu3(PO4)2·2Cu(OH)2、Cu3(PO4)2·Cu(OH)2And the like. As additives, basicCopper phosphate does not affect the color reproduction characteristics of the colorant, and thus allows a molded article having a desired color to be easily obtained.
In some embodiments, the LDS additive can have an average particle size of about 0.01 μm to about 50 μm, for example, about 0.1 μm to about 30 μm, specifically about 0.5 μm to about 10 μm.

In some embodiments, the LDS additive can be present in an amount of about 0.5 parts by weight to about 15 parts by weight, for example, about 1 part by weight to about 15 parts by weight, relative to about 100 parts by weight of the polycarbonate resin. If the content of the LDS additive is less than about 0.5 parts by weight relative to about 100 parts by weight of the polycarbonate resin, a sufficient amount of metal nuclei is not formed in the coating layer during irradiation of the thermoplastic resin composition (molded article) with a laser beam, resulting in deterioration of plating adhesion, and if the content of the LDS additive exceeds about 15 parts by weight, the thermoplastic resin composition may suffer from deterioration in impact resistance and heat resistance.
