2. Description of the Related Art Molded products of aromatic polycarbonate resins have excellent mechanical properties,
Due to its electrical and thermal properties, it can be used as an engineering plastic in OA equipment, electrical and electronic fields,
It is widely used in various fields such as automobiles and construction. Further, in order to solve the problem of the aromatic polycarbonate resin, which is slightly inferior in workability and moldability, polystyrene resin, acrylonitrile-butadiene-styrene (ABS) resin, polyester resin, etc. Many polymer blends with a thermoplastic resin have been developed, and among them, a polymer alloy with an ABS resin is widely used in the fields of automobiles, OA equipment, electric and electronic fields and the like.

On the other hand, in recent years, there has been a strong demand for flame-retardant resin materials used mainly for applications such as office automation equipment and home electric appliances. In order to meet these demands, aromatic polycarbonate resins and aromatic polycarbonate resins have been demanded. With respect to polymer alloys of the above and other thermoplastic resins, many proposals for making them flame-retardant have been made.

Conventionally, regarding the flame retardancy of aromatic polycarbonate resins or polymer alloys thereof, organic halogen-based flame retardants having bromine and antimony trioxide as described in, for example, JP-A No. 64-22958. It was common to use the above flame retardant aid together. The resin composition according to this formulation has a relatively large flame retardant effect,
There is an environmental problem that a harmful or toxic substance is generated at the time of fire occurrence or combustion by incineration, and further thermal decomposition generates hydrogen halide, corrodes the mold, and the resin molded product itself. However, there is a problem in production that various physical properties of For this reason, studies on flame-retardation that does not include an organohalogen compound having bromine have become popular.

For example, the combined use of a phosphoric acid ester and polytetrafluoroethylene capable of forming fibrils has been studied. Japanese Unexamined Patent Publication No. 61-55145 discloses a thermoplastic molding composition having antifouling properties, which comprises an aromatic polycarbonate resin, an ABS resin, an AS resin, a halogen compound, a phosphoric acid ester and polytetrafluoroethylene. Is listed. JP-A-2-32154 discloses an aromatic polycarbonate resin, an ABS resin,
A flame-retardant, high-impact polycarbonate molding composition comprising each of an AS resin, a phosphoric acid ester, and polytetrafluoroethylene is described. In the above publication,
It is disclosed that these components may additionally contain stabilizers, pigments, flow aids, fillers and reinforcing substances, release agents and / or antistatic agents. In addition, JP-A-2
Japanese Patent Publication No. 69557 describes a flame-retardant thermoplastic polycarbonate molding compound comprising an aromatic polycarbonate resin, an ABS resin, an AS resin, a specific phosphoric acid ester, and polytetrafluoroethylene. JP-A-2-115262 describes a flame-retardant composition containing an aromatic polycarbonate resin, an ABS resin and an oligomeric phosphate ester. However, in these flame retardant formulations using mainly phosphate ester, it is necessary to add a large amount of flame retardant,
Since the phosphoric acid ester is volatile, there are problems that the heat resistance becomes poor and the mold is contaminated.

On the other hand, since silicone resin has high heat resistance, does not generate toxic gas at the time of combustion, and has high safety of silicone resin itself, various kinds of flame retardants for polycarbonate resin are proposed. Is actually OA
It has come to be used for flame retarding resin compositions for devices.

Japanese Laid-Open Patent Publication No. 59-500909, Japanese Patent Laid-Open No. 4-1993
No. 226159 and JP-A-7-33971,

Are listed respectively. A silicone resin having such a branched structure is excellent in heat resistance, and a silicone resin containing a phenyl group is a non-combustible Si-C due to mutual coupling of aromatic rings on the surface of the resin to which it is added. It is described that a flame retardant effect is exhibited by forming a ceramic layer.

Further, Japanese Patent Application Laid-Open No. 54-102352 discloses a thermoplastic resin composition obtained by adding a silicone oligomer containing a polysubstituted ethoxy group to an aromatic polycarbonate resin, and Japanese Patent Application Laid-Open No. 6-306265 discloses a thermoplastic resin composition. A flame-retardant polycarbonate resin composition containing, as essential components, an aromatic polycarbonate resin, an alkali (earth) metal salt of perfluoroalkanesulfonic acid, and an organic siloxane having an alkoxy group, a vinyl group and a phenyl group is disclosed in JP-A-6-336547 also contains an organooxysilyl group bonded to a silicon atom via a divalent hydrocarbon group, in addition to an aromatic polycarbonate resin and an alkali (earth) metal salt of perfluoroalkanesulfonic acid. Flame-retardant polycarbonate resin set containing organopolysiloxane Things, JP-A-11-222559
JP-A No. 2000-226527 and JP-A No. 2000-226527 respectively describe flame-retardant resin compositions obtained by adding a phenyl group- and alkoxy group-containing organopolysiloxane to a synthetic resin containing an aromatic ring in the molecule. When these resin compositions are burned, the organopolysiloxanes or the organopolysiloxanes and the resin component are bonded to each other to form a network by oxidative decomposition and crosslinking of the alkoxy group or the organooxy group, and are fixed around the burning part. Therefore, it is considered that the flame retardant effect is exhibited.

Examples of the use of other types of silicone compounds are described in JP-A-6-128434 and Si-H group-containing organopolysiloxane described in JP-A-51-45160. The organopolysiloxane resin containing a siloxane unit having a vinyl group, the organopolysiloxane containing an epoxy group described in JP-A-8-176425, and the JP-A-8-176427. Examples thereof include a polycarbonate resin modified with a phenolic hydroxyl group-containing organopolysiloxane.

Further, addition of various silicone resins to a polymer alloy composed of an aromatic polycarbonate resin and another thermoplastic resin has also been studied, as disclosed in JP-A-62-62.
JP-A-297352 discloses that chemical resistance, weather resistance and heat resistance are improved by blending a silicone rubber. JP-A No. 7-126510 discloses a polyorganosiloxane rubber component and a polyalkyl (meth). It is described that the impact resistance can be improved by blending a composite rubber having a structure in which the acrylate rubber component is intertwined with each other so that it cannot be separated.

Similarly, addition of a silicone resin for the purpose of improving flame retardancy to such a polymer alloy has been proposed, and Japanese Patent Application Laid-Open No. 4-298554 discloses that.
The addition of a phosphoric acid ester compound and a polyorganosiloxane is disclosed, and in the examples, use of polymethylphenylsiloxane or low density polyethylene-modified polysiloxane is exemplified. In addition, JP-A-5-1791

However, in any of the above flame retardant compositions, the silicone flame retardant is merely used as an auxiliary agent in addition to the phosphate ester flame retardant,
No silicone-based flame retardant has been found that can provide flame retardant effects when used alone for polymer alloys.

On the other hand, in OA equipment, home electric appliances, etc., the tendency toward lightness, thinness, shortness, and resource saving has become more and more intense, and accordingly, higher flame retardancy is safer, and corrosive gases are generated during molding. There is a demand for the development of an aromatic polycarbonate-based resin composition that can be achieved by using a material that does not contain a flame-retardant resin, and that enables reuse of a molded article produced from such a flame-retardant resin composition.

The present invention relates to an aromatic polycarbonate resin or a polymer alloy composed of an aromatic polycarbonate resin and another thermoplastic resin, which has the above-mentioned environmental and manufacturing problems, such as an organic halogen-based flame retardant and a heat-resistant material. And a flame-retardant resin composition having a sufficient flame-retarding effect without using a phosphate ester-based flame retardant, which is problematic in terms of mold contamination, and is safe and has a low environmental load, and The object is to provide a molded product obtained.

It is preferably 0 g. The Si-H content referred to here is the number of mols of Si-H groups contained per 100 g of organopolysiloxane, which is hydrogen generated per unit weight of organopolysiloxane by the alkali decomposition method. It can be determined by measuring the gas volume. For example, when hydrogen gas of 122 ml is generated per 1 g of organopolysiloxane at 25 ° C., the Si—H content is 0.5 m according to the following calculation formula.

It is 0.1 to 10 parts by weight with respect to parts by weight. If the addition amount of the organopolysiloxane is less than 0.1 parts by weight, the flame retarding effect will be insufficient, and if it exceeds 10 parts by weight, the flame retarding effect will not be improved and the mechanical properties such as impact resistance will not be improved.
