Description

  The present invention relates to a flame retardant polycarbonate resin composition, and more particularly, a terpene resin, an organometallic salt compound, an amide compound and a fiber-forming fluoropolymer, and optionally an organic acid and / or an inorganic filler.

  Polycarbonate resin is a thermoplastic resin excellent in impact resistance, heat resistance, and the like, and is widely used in fields such as electric / electronic / OA, machinery, automobiles, and building materials. Among these, in the field of electrical / electronic / OA, there are many parts that require high flame resistance (UL94V) and impact resistance, such as personal computer exterior parts. Polycarbonate resin is a highly flame-retardant plastic material with self-extinguishing properties. However, in order to meet safety requirements in the electric, electronic, and OA fields, it has higher flame resistance equivalent to UL94V-0 and V-1. Is required.

  Therefore, in order to improve the flame retardancy of the polycarbonate resin, conventionally, a method of blending a halogen compound or a phosphorus compound as a flame retardant has been adopted. However, flame retardant polycarbonate resins that do not use halogen-based and phosphorus-based flame retardants have been demanded from the viewpoint of the environment.

  On the other hand, terpene resins have been used for flame-retardant polycarbonate resins (Patent Documents 1 and 2), but terpene resins are not used as those that provide a flame-retardant effect. The flame retardant was achieved by adding a flame retardant such as. In general, as a technique for improving the fluidity of a polycarbonate resin composition, a method of blending a low molecular weight compound or a polymer having high fluidity has been proposed (Patent Documents 3 and 4).

  The compounding quantity of the terpene resin (B) with respect to a polycarbonate resin (A) is 0.5 to 10 weight%. A blending amount of less than 0.5% by weight is not preferable because sufficient flame retardancy is not exhibited. On the other hand, if it exceeds 10% by weight, the impact strength is lowered, and if the thermal history is received, the resin composition is discolored, which is not preferable. Preferably it is the range of 2 to 5 weight%.

When the inorganic filler (G) is blended, the shape retention during combustion of the thin molded article is remarkably increased, and the flame retardancy is improved. When the blending amount of the inorganic filler (G) exceeds 50 parts by weight, the molecular weight of the polycarbonate resin is lowered during granulation, which is unfavorable for stable production. This amount is preferably in the range of 2 to 20 parts by weight, more preferably 3 to 15 parts by weight. In this range, the balance of granulation workability, flame retardancy, and moldability is further improved.
