Problems solved by technology

[0007] However, in this improved technique, since the organopolysiloxane is oily or gel-like, the tensile strength of the resin composition decreases in proportion to the compounding amount of the organopolysiloxane, which is a disadvantage.

Embodiment

[0053] The present invention will be specifically described below using examples and comparative examples, but the present invention is not limited to the following examples. It should be noted that the numbers in the column of raw materials in Table 1 represent the compounding amounts in parts by mass.

[0054] The various raw materials shown in Table 1 were added to a Laboratory Plastic Mixer R250 (manufactured by Toyo Seiki Co., Ltd., trade name), and mixed under the conditions of 150 ° C, 30 rpm, and 10 minutes. Extrude granulation, and pressurize the granules under the condition of 150°C and 1 minute of pressure to make two kinds of test sheets with a thickness of 1 mm and a thickness of 3 mm.

Abstract

To provide a nonhalogen flame retardant resin composition which exhibits high flame retardance and excels in tensile strength, does not generate a halogen gas on combustion, and excels in safety for the environment. The nonhalogen flame retardant composition comprises (A) 100 pts. mass one or more carboxylic anhydride group-free thermoplastic resins, (B) 0.1-30 pts. mass carboxylic anhydride group-containing resin, (C) 40-300 pts. mass inorganic flame retardant, and (D) 0.1-100 pts. mass organopolysiloxane.

Description

technical field [0001] The present invention relates to a halogen-free flame-retardant resin composition which has high flame retardancy and tensile strength and is excellent in environmental safety because no halogen gas is generated during combustion. Background technique [0002] Since thermoplastic resins are flammable, various techniques for imparting flame retardancy have been proposed in order to be able to adapt to applications requiring flame retardancy. Conventionally, as a technology for imparting flame retardancy, halogen formulations have been widely used, that is, halogen-based flame retardants such as bromine compounds that impart excellent flame retardancy are used, and these are blended with antimony oxide into thermoplastic resins. Halogen-based flame retardants exhibit excellent flame-retardant effects due to the free radical capture function and the generation of incombustible gases. [0003] However, since halogen-based flame retardants generate a large...
