The rubber-modified styrene-based resin thus prepared is used in food containers, electrical, It is widely used as a part of electronic products.

그러나, 통상적인 고충격 폴리스티렌 수지의 경우는 대전방지성이 없어 반도체 부품 트레이(Tray)용으로 사용하는 경우 정전기가 발생하여 먼지가 달라붙는 문제점이 있다.However, conventional high-impact polystyrene resins do not have antistatic properties, and when used for a semiconductor component tray (Tray), there is a problem in that static electricity is generated and dust adheres.

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

고무변성된 스티렌계 수지는 모노비닐 방향족 화합물 90 내지 92중량부와 폴리부타디엔계 고무 8 내지 10중량부를 첨가하고 여기에 상온에서 54 내지 76 센티스토크의 점도를 갖는 유동파라핀계 미네랄오일 1.0 내지 2.5중량부 및 산화방지제인 트리에틸렌글리콜-비스-3-(3-t-부틸-4-하이드록시-5-메틸페닐)프로피오네이트[triethyleneglycol-bis-3-(3-t-butyl-4-hydroxy-5-methylphenyl)propionate] 0.05 내지 0.1중량부를 투입하여 열에 의한 괴상연속중합법에 의해 제조되는 것으로 중량평균분자량 19 내지 22만의 범위의 것이다The rubber-modified styrene resin is 90 to 92 parts by weight of a monovinyl aromatic compound and 8 to 10 parts by weight of polybutadiene rubber, and 1.0 to 2.5 parts by weight of liquid paraffinic mineral oil having a viscosity of 54 to 76 centistokes at room temperature. Triethyleneglycol-bis-3- (3-t-butyl-4-hydroxy-), a minor and antioxidant, triethyleneglycol-bis-3- (3-t-butyl-4-hydroxy- 5-methylphenyl) propionate] is prepared by the mass continuous polymerization method by adding 0.05 to 0.1 parts by weight, and has a weight average molecular weight in the range of 19 to 220,000.

바람직한 모노비닐 방향족 화합물로는 스티렌, α-메틸스티렌, α-에틸스티렌, p-메틸스티렌 등을 들 수 있다. 폴리부타디엔계 고무는 1,4-cis 함량이 95중량% 이하이며 전제수지 조성물 100중량부에 대하여 95중량%의 스티렌 모노머 용액에서 용액점도가 25℃에서 20 내지 80센티포아즈 수준으로 폴리스티렌 상에 분산된 고무상 물질의 평균입경은 1.0 내지 3.0미크론의 분포를 갖는 것이 사용된다.Preferred monovinyl aromatic compounds include styrene, α-methylstyrene, α-ethylstyrene, p-methylstyrene and the like. The polybutadiene-based rubber has a 1,4-cis content of not more than 95% by weight and has a solution viscosity of 20 to 80 centipoise at 25 ° C. in a 95% by weight styrene monomer solution based on 100 parts by weight of the total resin composition. The average particle diameter of the dispersed rubbery material is used having a distribution of 1.0 to 3.0 microns.

폴리부타디엔계 고무는 전체 수지 조성물 100중량부에 대하여 8 내지 10중량부로 사용하는 것이 바람직한데, 8중량부 미만인 경우에는 내충격성과 신율이 저하되고, 10중량부를 초과하는 경우에는 내열성과 강성이 저하되어 바람직하지 못하다. 또한, 고무상 물질의 평균입경이 1.0미크론 미만인 경우에는 내충격성이 저하되고, 3.0 미크론을 초과하는 경우에는 표면광택도가 저하되어 바람직하지 못하다.The polybutadiene-based rubber is preferably used in an amount of 8 to 10 parts by weight based on 100 parts by weight of the total resin composition. When it is less than 8 parts by weight, impact resistance and elongation are lowered, and when it exceeds 10 parts by weight, heat resistance and rigidity are decreased. Not desirable Moreover, when the average particle diameter of a rubbery material is less than 1.0 micron, impact resistance falls, and when it exceeds 3.0 microns, surface glossiness falls and it is unpreferable.

미네랄오일은 1.0중량부 미만인 경우에는 유동성이 저하되고, 2.5중량부를 초과하는 경우에는 내열성이 떨어진다.If the mineral oil is less than 1.0 parts by weight, the fluidity is lowered, and if it is more than 2.5 parts by weight, the heat resistance is inferior.

최종 중합물의 중량평균분자량은 중합온도, 반응기중량을 조절하여 19만 내지 22만이 되도록 하는 것이 바람직한데, 중량평균분자량이 19만 미만인 경우에는 강성이 떨어지고 22만을 초과하는 경우에는 유동성이 저하되어 바람직하지 못하다.The weight average molecular weight of the final polymer is preferably adjusted to only 190,000 to 22 by adjusting the polymerization temperature and the reactor weight. When the weight average molecular weight is less than 190,000, the rigidity is lowered. Can not do it.

고무변성된 스티렌계 수지의 중합법으로는 괴상연속중합법으로 중합하는 것이 바람직한데, 이는 괴상연속중합법에 의할 경우 대량생산으로 제조원가가 저렴해지고 균일한 물성을 갖는 제품을 생산하기 쉽기 때문이다.Polymerization of rubber-modified styrene-based resins is preferably carried out by a bulk continuous polymerization method, since the bulk continuous polymerization method makes it easy to produce a product with low production cost and uniform properties by mass production. .

이상에서와 같이 제조된 고무변성된 스티렌계 수지에 첨가되는 음이온계면활성제 혼합물은 황염소화되고 수산화나트륨으로 비누화된 파라핀오릴과 마그네슘염성분으로 되어 있고, 사용량은 1.0 내지 3.0 중량부가 바람직하다. 음이온계면활성제 혼합물의 사용량이 1.0중량부 미만인 경우에는 대전방지성(대전압반감기, 표면저항)이 불량해지고, 3.0중량부를 초과하는 경우에는 성형품에 박리현상이 발생되어 바람직하지 못하다.The anionic surfactant mixture added to the rubber-modified styrene resin prepared as described above is composed of paraffin oryl and magnesium salts sulphated and saponified with sodium hydroxide, and the amount is preferably 1.0 to 3.0 parts by weight. If the amount of the anionic surfactant mixture is less than 1.0 part by weight, the antistatic property (large voltage half-life, surface resistance) is poor, and if it exceeds 3.0 parts by weight, peeling occurs in the molded article, which is not preferable.

본 발명에서 사용된 글리세릴 모노스테아레이트는 55 내지 70℃의 융점 범위 를 갖고 80℃에서 벌크덴시티(bulk density)가 0.890 내지 0.896범위를 갖는 것으로 0.05 내지 1.0중량부가 사용된다. 글리세릴 모노스테아레이트의 사용량이 0.05중량부 미만인 경우에는 대전방지성이 나빠지고, 1.0중량부를 초과하는 경우에는 성형물표면에 가스자국이 생겨 바람직하지 못하다.Glyceryl monostearate used in the present invention has a melting point range of 55 to 70 ℃ and a bulk density at 0.8 ℃ to have a range of 0.890 to 0.896 is used 0.05 to 1.0 parts by weight. If the amount of the glyceryl monostearate is less than 0.05 part by weight, the antistatic property is worsened. If the amount of the glyceryl monostearate is less than 1.0 part by weight, gas traces are formed on the surface of the molding, which is not preferable.

징크-스테아레이트는 고급지방산의 금속염으로 0.01 내지 0.1중량부가 사용되고, 이산화티탄은 비중이 4.2인 백색분말의 형상을 갖는 것이 사용된다. 징크스테아레이트 및 이산화티탄의 함량이 각각 0.01중량부 및 0.3중량부 미만으로 사용되면 대전방지성이 급격히 저하되고, 0.1중량부 및 0.7중량부를 초과하여 사용하여도 대전방지성은 더 이상 향상되지 않으므로 본 발명의 범위내로 사용하는 것이 가장 바람직하다.Zinc-stearate is used as a metal salt of higher fatty acids, 0.01 to 0.1 parts by weight, and titanium dioxide is used having a shape of a white powder having a specific gravity of 4.2. When the content of zinc stearate and titanium dioxide is less than 0.01 parts by weight and 0.3 parts by weight, respectively, the antistatic property is drastically reduced, and even when used in excess of 0.1 part and 0.7 parts by weight, the antistatic property is no longer improved. Most preferably used within the scope of the invention.
