の低下は防ぎ得なかった。2. Description of the Related Art An impact-resistant polystyrene resin (hereinafter referred to as HIP) widely used for molding electric equipment, OA equipment, automobile parts, household goods and the like.
S) is generally very flammable and has the drawback that if a flame is brought close to a part of the molded product and starts to burn, it will continue to burn naturally even if the flame is moved away. In recent years, requirements for flame retardancy have become severe due to the need for fire safety. In particular, electrical equipment and OA equipment are required to pass the UL (Underwriters Laboratory) UL-94V0 standard. Fields are expanding.
In order to pass the UL-94V0 standard, it is required that there is no dripping during combustion. Conventionally, as a method of making a styrene-based resin flame-retardant, it is known to mix a styrene-based resin with a flame retardant such as an organic bromine compound or a flame retardant auxiliary such as antimony trioxide. In this case, dripping cannot be prevented, so that it does not pass the UL-94V0 standard, and furthermore, a large amount of a flame retardant is mixed in, so that the excellent impact resistance of HIPS is significantly reduced. Was. As a method for preventing dripping, for example, a method in which an inorganic filler such as talc, clay, or glass fiber is mixed into the above-described composition, or polytetrafluoroethylene (for example,
0-44241), and a method of mixing a chlorinated polyethylene having a chlorine content of 25 to 50% by weight (for example, JP-A-50-94066).
Although dripping can be prevented, it is difficult to maintain the inherently excellent impact resistance of the impact-resistant polystyrene resin. Further, the method of mixing chlorinated polyethylene having a chlorine content of 25 to 50% by weight is not suitable for heat stability of HIPS. Therefore, the practical value was low because the property was also significantly reduced.
Further, Japanese Patent Application Laid-Open No. 54-68855 of the present applicant discloses that styrene-butadiene copolymer (hereinafter abbreviated as SBR) is added to chlorinated polyethylene having a chlorine content of 25 to 50% by weight.
Although the method of mixing HIPS has been proposed, even in this method, the impact resistance of HIPS can be maintained, but a decrease in thermal stability cannot be prevented.

力が著しく低下し実用的でない。[0004] When only SBR is blended with HIPS, the impact resistance can be improved but dripping cannot be prevented.
Further, even if the butadiene content in HIPS is increased, the tensile strength decreases, so that the combination of the anti-drip property and the excellent impact resistance is achieved only in the presence of the three components of HIPS, SBR and chlorinated polyethylene. The HIPS used in the present invention is mainly composed of a styrene-based polymer. In the presence of rubber-like substances such as polybutadiene, butadiene-styrene copolymer rubber, and ethylene-propylene diene copolymer rubber, styrene, α Graft copolymer obtained by polymerizing one or more styrene monomers such as methylstyrene, vinyltoluene, chlorostyrene, etc .; homopolymer or copolymer obtained by polymerizing the rubbery substance and the styrene monomer; It refers to a blend by post-mixing with a polymer. The SBR used in the present invention is preferably a styrene-butadiene copolymer having a butadiene content of 50 to 80% by weight. If the butadiene content exceeds 80% by weight, the compatibility with HIPS decreases and the physical properties of HIPS decrease, and if it is less than 50% by weight, sufficient impact resistance cannot be obtained. From the viewpoint of compatibility with HIPS, a styrene-butadiene-styrene triblock copolymer is more preferably used. About HI
The content is 2 to 10 parts by weight, more preferably 2 to 7 parts by weight, based on 100 parts by weight of PS.

For example, decabromodiphenyl oxide, tetrabromobisphenol A, hexabromobenzene, brominated bisphenol carbonate oligomer, brominated epoxy And the like. The compounding amount of the flame retardant is 10 to 30 parts by weight of a brominated flame retardant and 3 to 10 parts by weight of antimony trioxide with respect to 100 parts by weight of HIPS. If the amount is less than the respective ranges, sufficient flame retardancy cannot be obtained. If the amount exceeds the range, the mechanical properties are remarkably deteriorated, and it is economically disadvantageous.

レンを用いた場合に特に良い結果が得られる。The chlorinated polyethylene used in the present invention is made of polyethylene having a weight average molecular weight of 200,000 to 800,000 and a chlorine content of 5 to 20% by weight, more preferably 7 to 13% by weight. good. When the weight average molecular weight of the raw material polyethylene is less than 200,000, both the drip resistance and impact resistance are insufficient, and when it exceeds 800,000, the moldability is deteriorated, which is not preferable. If the chlorine content is less than 5% by weight, the anti-drip property and the impact resistance are inferior.
If the amount is more than 10% by weight, the thermal stability is significantly reduced. The heat of fusion measured by differential scanning calorimetry (DSC) is 3 to 15.
Using cal / g chlorinated polyethylene, HIPS
The dispersibility of the chlorinated polyethylene therein is improved, and more excellent anti-drip properties are obtained. About HIPS
The amount is 1 to 10 parts by weight, more preferably 2 to 5 parts by weight, per 100 parts by weight. If the amount is less than 1 part by weight, sufficient anti-drip property cannot be obtained, and if it exceeds 10 parts by weight, tensile strength, moldability, and thermal stability decrease. There are two main methods for producing chlorinated polyethylene: a method of chlorinating polyethylene in a carbon tetrachloride solvent and a method of chlorinating polyethylene suspended in water. The latter aqueous suspension chlorination method ( For example, particularly good results are obtained when chlorinated polyethylene produced in Japanese Patent Publication No. 46-21729 is used.
