Definitions

  • the present invention relates to a non-halogen flame retardant polycarbonate resin composition having excellent infrared transmissivity and non-halogen flame retardancy imparted by incorporating a mixture of aromatic phosphate as a non-halogen flame retardant and fluoroolefin into a polycarbonate resin.
  • a polycarbonate resin per se has high infrared transmissivity.
  • aromatic phosphate and fluoroolefin which are typically used to impart flame retardancy necessary for an external ornament of electric/electronic products, results in rapid deterioration of infrared transmissivity of the product.
  • This approach has low infrared transmissivity, thus suffering from limitations of application thereof to products requiring infrared remote control operation, such as TV front cabinet and the like.
  • the present invention has been made in view of the above problems, and it is an object of the present invention to provide a flame retardant polycarbonate resin composition having excellent infrared transmissivity, by using non-halogen aromatic phosphate having excellent compatibility with a polycarbonate resin and thus causing no deterioration of infrared transmissivity even when a given amount of the non-ha logen aromatic phosphate is mixed with the polycarbonate resin and by using fluoroolefin having excellent dispersibility.
  • a flame retardant thermoplastic resin composition comprising (A) 83 to 93% by weight of a polycarbonate resin, (B) 6 to 17% by weight of aromatic phosphate, and (C) 0.08 to 0.3% by weight of fluoroolefin.
  • the polycarbonate resin is a compound prepared by reacting a divalent phenolic compound with a phosgene or carbonic acid diester and containing no halogen.
  • the aromatic phosphate is a non-halogen flame retardant and is selected from aromatic monophosphate, aromatic diphosphate and a mixture thereof.
  • the aromatic monophosphate is preferably selected from the group consisting of non-halogen substituted triarylphosphate and trialkyl-arylphosphate.
  • the triarylphosphate is selected from the group consisting of triph- enylphosphate, tricresylphosphate, trixylenylphosphate and cresyldiphenylphosphate
  • the trialkyl-arylphosphate is preferably octyldiphenylphosphate.
  • the aromatic diphosphate is preferably a compound represented by Formula 1:
  • Ar to Ar are each independently phenyl or aryl substituted with one to three C -C alkyl, R is phenyl or bisphenol A, and l ⁇ n ⁇ 2.
  • the fluoroolefin is preferably selected from fluorinated polyethylene, and fluoroethylene with attachment of a thermoplastic resin or organic material.
  • the thermoplastic resin or organic material-bound fluoroethylene may include compounds having a core- shell structure where the core is fluoroethylene and the shell is a thermoplastic resin or organic material, and compounds having fluoroethylene with partial branching of a thermoplastic polymer or organic material.
  • the fluoroethylene compound is a compound having partial attachment of a thermoplastic polymer or organic material to fluoroethylene or is a core- shell type compound, superior dispersibility is obtained as compared to use of fluoroethylene alone.
  • To fluoroethylene is largely attached a styrene organic material or a thermoplastic polymer partially containing a styrene-based moiety, or an acrylic organic material or a thermoplastic polymer partially containing an acrylic moiety.
  • the fluoroethylene is preferably polytetrafluorethylene (PTFE).
  • Examples of conventional additives that can be added to the resin composition of the present invention may include an antioxidant, a weathering stabilizer, a lubricant, a silicon supplement, a release agent, a pigment, a dye, an antistatic agent, an antibacterial agent, a processing aid, and antiabrasive. These additives can be used within a proper content.
  • mixing of composition components may be carried out by a conventional method involving dry blending of the components, followed by heating and melt-mixing.
  • the mixing process is carried out typically at a temperature of 24O 0 C to 300 0 C, preferably 26O 0 C to 27O 0 C, such that the individual components can sufficiently maintain physicochemical affinity therebetween.
  • the resulting composition may be subjected to a molding method such as injection molding, extrusion molding, blow molding, or the like, which is conventionally employed in molding of polycarbonate.
  • the present invention provides a polycarbonate resin composition with superior infrared transmissivity and flame retardancy. Therefore, the resin composition of the present invention can be used for applications of non-coated external parts of electric/ electronic appliances to which an infrared controller is applied.
  • MFI was measured at 300 0 C and a load of 1.2 kg, according to ASTM D 1238.
  • PC polycarbonate
  • PC polycarbonate
  • Comparative Example 2 A specimen was prepared and tested in the same manner as in Comparative Example 1, except that 94.8% by weight of PC, 5% by weight of aromatic phosphate, and 0.3% by weight of fluoroolefin were melt-mixed and pelletized at 28O 0 C to obtain a resin composition. The results are given in Table 1 below.
  • Comparative Example 3 A specimen was prepared and tested in the same manner as in Comparative Example 1, except that 87.6% by weight of PC, 12% by weight of aromatic phosphate, and 0.4% by weight of fluoroolefin were used. The results are given in Table 1 below.
  • Aromatic phosphate exhibits flame retardancy. That is, when it is combusted, the aromatic phosphate produces polymetaphosphate by pyrolysis and the resulting poly- metaphosphate forms a protective layer on a resin, thereby providing flame retardancy. Fluoroolefin is added to prevent the occurrence of dripping upon combustion of the resin. Higher contents of the aromatic phosphate and fluoroolefin provide higher flame retardancy.
  • the content of fluoroolefin exhibits the most significant effects on the infrared transmissivity and flame retardancy.
  • the resin composition of the present invention maintain high infrared transmissivity and flame retardancy V-O. It can be seen from Examples 1 to 3 that the resin composition of the present invention exhibiting these effects is a composition containing 6 to 17% by weight of aromatic phosphate and 0.08 to 0.3% by weight of fluoroolefin.
