A novel tri-substituted triphenyl isocyanurate is defined by the following formula and useful as a crossliking agent for resin.
wherein X represents -O- or -COO-; and R represents a hydrogen atom, a straight-chain or branched alkyl group having 1 to 10 carbon atoms which may be either unsubstituted or substituted with a hydroxyl group, an aryl group or an R'₃Si group (wherein a plurality of R' groups may be the same or different from each other and each represent a straight-chain or branched alkyl group having 1 to 10 carbon atoms or a phenyl group), excepting the case wherein X is -O- and R is CH₃.

To provide a flame retardant polyolefin resin composition having an excellent flame retardancy and enabling the preparation of a molded product free from soapiness, a flame retardant polyolefin resin composition comprises (A) 100 parts by mass of a polyolefin resin, (B) 10 to 60 parts by mass of melamine polyphosphate and (C) 10 to 60 parts by mass of a carbonizing agent, wherein the compounding ratio [(B)/(C)] of the component (B) to the component (C) (mass ratio) is in a range from 0.5 to 4.5, optionally further including (D) 1 to 30 parts by mass of a carbonizing promoter.
A self-extinguishing resin molded body obtained from a resin composition containing a polyolefin resin (A), a phosphorus-based flame retardant (B), and a glass fiber (C), wherein the self-extinguishing resin molded body contains from 15 to 30 mass% of the phosphorus-based flame retardant (B) and from 5 to 50 mass% of the glass fiber (C); and the self-extinguishing resin molded body satisfies the following (I) to (III). (I) A thickness of the self-extinguishing resin molded body is from 1.5 to 8.0 mm. (II) The self-extinguishing resin molded body self-extinguishes within 2 minutes after the completion of a burning test using burning test method E as described below. (III) The self-extinguishing resin molded body does not have a hole after being subjected to a burning test using burning test method E as described below. Burning test method E: A plaque (150 × 150 × 2.0 mm) made of the molded body described above is used. A 200 mm-long flame is applied from above the plaque directly onto the center of the plaque for 130 seconds. The distance from the flame contact position on the plaque to the burner mouth is 150 mm.
A resin molded body obtained from a resin composition containing a thermoplastic resin (A), a flame retardant (B), and a metal fiber (C). The resin molded body contains from 15 to 30 mass% of the flame retardant (B) and from 2.5 to 7.5 mass% of the metal fiber (C), with the remainder being component (A) to make a total of 100 mass%. The resin molded body has a determination result of V-0 or V-1 in a burning test using the UL 94 V test method on a test piece having a thickness of 1.5 mm. The resin molded body satisfies the requirements described in the following (I) to (IV). (I) A thickness of the resin molded body is from 1.5 to 8.0 mm. (II) The resin molded body self-extinguishes within five minutes after the completion of a burning test using burning test method E as described below. (III) The resin molded body does not have a hole after being subjected to a burning test using burning test method E as described below. (IV) The resin molded body has an electromagnetic wave shielding property of more than 30 dB using a KEC method electric field in a frequency range from 1 to 100 MHz. Burning test method E: A plaque (150 × 150 × 2.0 mm) made of the molded body described above is used. A 200 mm-long flame is applied from above the plaque directly onto the center of the plaque for 130 seconds. The distance from the flame contact position on the plaque to the burner mouth is 150 mm.
