Definitions

  • the present invention relates to novel flame-retardant polypropylene resin compositions, which exhibit high incombustibility while being fine in other mechanical properties such as impact resistance, etc. More specifically, the present invention relates to incombustible polypropylene resin compositions comprising an organic flame retardant, an inorganic flame retardant and an antimony compound besides the major component, polypropylene resin in specific ratios.
  • polypropylene resins have been widely used, in the form of injection-molding products, films or blow-molding products, in various fields such as parts of automobiles, building materials, parts of electrical appliances, etc.
  • they are essentially inflammable, so they need to be supplemented with a variety of organic or inorganic flame retardants in order to obtain incombustibility.
  • organic or inorganic flame retardant in combination with antimony trioxide is used to make polypropylene resins incombustible .
  • Exemplary incombustible polypropylene resin compositions containing such flame retardants include compositions prepared by adding to a polypropylene resin a bromine-based flame retardant such as decabromodiphenylether, bis (pentabromophenyl) ethane, etc. (See: Japanese Laid-open Publication Nos. HEI 8-120126 and HEI 7-76640) ; compositions prepared by adding to a polypropylene resin a tetrabromo bisphenol A-based or tetrabromo bisphenol S-based flame retardant (See : Japanese Laid-open Publication No.

  • compositions which were prepared by adding an inorganic compound such as magnesium hydroxide to a polypropylene resin in order to obtain a highly incombustible resin composition, were found to be poor in plasticity.
  • compositions prepared by adding a decabromophenyl-based compound to a polypropylene resin are not very poor in plasticity, but their impact resistance is very low.
  • a feature of the present invention is to solve these problems of the prior arts and to provide novel incombustible polypropylene resin compositions showing the high incombustibility of 5V grade in a state of thin plate, and, at the same time, showing excellent impact resistance and thermal resistance, by adding, to a polypropylene resin, i) a bromine-based flame retardant having a specific structure, ii) an antimony compound as a synergist of the flame retardant, iii) a magnesium hydroxide as an inorganic flame retardant, and iv) a chlorinated polyethylene as both a modifier of impact resistance and an auxiliary flame retardant.

  • polypropylene refers to propylene homopoly er as well as propylene-olefin block copolymer containing 50 wt% or more polypropylene unit.
  • the polypropylene resin (A) may be a crystalline polypropylene homopolymer, or a crystalline copolymer consisting of propylene and one or more compounds selected from the group consisting of ethylene, 1-butene, 1-pentene, 1-hexene, 4-methylpentene, 1-heptene, 1-octene and 1-decene.
  • Melt index of the polypropylene resin is in the range of 0.1 ⁇ 60g/10min, preferably 0.3 ⁇ 40g/10min.
  • melt index of the polypropylene resin is below O.lg/lO in, excessive pressure is loaded during injection molding and flow marks occur on the surface of the molding products, and thus defect in appearance is resulted. Conversely, if the melt index of the polypropylene resin is over 60g/10min, impact resistance of the molding products becomes lower suddenly and drip of ignitable melted material is likely to occur. According to the present invention, any of the conventional crystalline polypropylene resins can be used regardless of their stereoregularity.

  • amount of the polypropylene resin (A) is 31 ⁇ 61% by weight, and preferably 35 ⁇ 58% by weight. If the polypropylene resin content is below 31% by weight, plasticity and impact resistance of the resin composition decrease in spite of high thermal resistance. Conversely, if the polypropylene resin content is over 61% by weight, thermal resistance and incombustibility of the resin composition decrease in spite of good plasticity and impact resistance, and therefore the composition cannot be used in parts requiring all of thermal resistance, incombustibility and impact resistance.

  • R is oxygen atom or C ⁇ 6 alkyl group; i is an integer of 0 ⁇ 5; and j is an integer of 1-5)
  • the alkyl group is preferably methyl or ethyl group.
  • amount of the bromine-based flame retardant (B) is 13 ⁇ 35% by weight. If the bromine-based flame retardant content is below 13% by weight, flameproof effect is insufficient to obtain the incombustibility corresponding to UL94 5V grade. Conversely, if the bromine-based flame retardant content is over 35% by weight, overall mechanical properties of the composition, particularly thermal resistance and tensile strength are spoiled, and electrical properties are also lowered.
  • the antimony trioxide (C) used as an auxiliary flame retardant is commercially available. Any antimony trioxide in powder form can used, wherein mean particle size of the powder, preferably, ranges from 0.2 to 5.0 ⁇ m.
  • amount of the antimony trioxide (C) is 3-21% by weight. If the antimony trioxide is contained below 3% by weight, synergistic effect with the bromine-based flame retardant is too low to achieve the incombustibility of UL94 5V grade. On the contrary, if the antimony trioxide is contained over 21% by weight, there is no more increase in the synergistic effect and impact resistance is significantly declined.
  • the antimony trioxide (C) and the bromine-based flame retardant (B) show a synergism in improving incombustibility. Especially, when the antimony trioxide is 1/6-2 times as much as the bromine-based flame retardant, this synergism is optimized.
  • the magnesium hydroxide (D) used as an inorganic flame retardant according to the present invention plays an important role in the composition. That is, the magnesium hydroxide absorbs the heat of reaction in the event of combustion of the resin to be decomposed into moisture. This, together with the synergism between the bromine-based flame retardant and the antimony trioxide as described above, enables the incombustibility of the resin composition to be highly improved. Moreover, the magnesium hydroxide prevents ignitable melted material from dripping during combustion, so that generation of drippirig substances, such as those defined in the incombustibility grade 5V according to "UL94 COMBUSTIBILITY TEST", can be avoided.
  • amount of the magnesium hydroxide (D) is 3-30% by weight. If the magnesium hydroxide content is below 3% by weight, the heat of combustion is not sufficiently absorbed, so that the synergistic effect on improvement of incombustibility is little, and further the drip of the melted material is not properly prevented. Conversely, if the magnesium hydroxide content is over 30% by weight, the composition is poor in fluidity and the other mechanical properties such as impact resistance and tensile strength, and its plasticity is also lowered.
  • the inorganic flame retardant used in the present invention an agent whose surface is treated with a silane- based coupling agent or with a metal stearate is preferred.
  • the resin composition is poor in mechanical properties including impact resistance.
  • the chlorinated polyethylene (E) used in the present invention is a polyethylene wherein some of hydrogen atoms are substituted with chlorine atoms.
  • chlorinated polyethylene has a characteristic of rubber rather than that of the usual polyethylene itself, and so it acts as both a modifier of impact resistance and a flame retardant.
  • the chlorinated ethylene improves impact resistance of the resin composition, and also improves incombustibility of the resin composition through providing the halogen element to the composition.
  • the chlorinated polyethylene used as an impact-resistant stiffener and an auxiliary flame retardant contains preferably 20-50 wt% of chlorine, and its amount is 2-15% by weight. If chlorine content of the chlorinated polyethylene is below 20 wt%, effect on improvement of impact resistance is slight. On the contrary, chlorine content of the chlorinated polyethylene is over 50 wt%, thermal degradation readily occurs during processing because of inherent low thermal stability of the chlorinated polyethylene. Meanwhile, if the chlorinated polyethylene content is below 2 wt% in the composition, sufficient reinforcing effect against impact can not be expected. Conversely, if the chlorinated polyethylene content is over 15 wt%, thermal stability significantly decreases .
  • incombustible resin compositions of the present invention may be added supplementary additives in order to further improve the mechanical properties such as stiffness and so on and thermal resistance of the composition.
