Description
본 발명은 내열 내충격 열가소성 수지 조성물에 관한 것으로서, 보다 상세하게는 말레이미드계 열가소성 수지를 제조하는데 있어 최종 라텍스의 입자크기를 조절한 말레이미드계 열가소성 수지를 사용하므로써 내열성이 극히 우수하고 내충격성 및 가공성이 양회한 열가소성 수지 조성물에 관한 것이다.The present invention relates to a heat-resistant impact thermoplastic resin composition, and more particularly, to manufacturing a maleimide-based thermoplastic resin, by using a maleimide-based thermoplastic resin in which the particle size of the final latex is adjusted, the heat resistance is extremely excellent, and the impact resistance and processability It relates to the obtained thermoplastic resin composition.
최근 자동차 경량화의 필요성으로 인하여 내열 내충격성등의 제반물성이 우수한 수지의 개발이 요구되고 있다.Recently, due to the necessity of weight reduction of automobiles, development of a resin having excellent physical properties such as heat resistance and impact resistance is required.
그중 수지의 내열성향상을 위하여 스티렌의 일정량을 α-메틸스티렌으로 대체하여 내열성수지를 제조하는 방법이 널리 이용되고 있으며, 그외에 폴리카보네이트와 ABS수지 블렌드 또는 폴리프로필렌수지에 무기물을 충진하여 내열성을 향상시키는 방법이 있다.Among them, in order to improve the heat resistance of the resin, a method of manufacturing a heat resistant resin by replacing a predetermined amount of styrene with α-methyl styrene is widely used.In addition, the heat resistance is improved by filling an inorganic material with a polycarbonate and ABS resin blend or a polypropylene resin. There is a way to.
그러나 α-메틸스티렌을 이용하여 내열성수지를 제조하는 경우 α-메틸스티렌의 종합속도가 느리고 가공시 열안정성이 떨어지는 단점이 있으며, 내열성 향상에 한계가 있다.However, in the case of manufacturing a heat resistant resin using α-methylstyrene, there is a disadvantage in that the overall speed of α-methylstyrene is slow and the thermal stability is poor during processing, and there is a limit in improving heat resistance.
또한 폴리카보네이트와 ABS수지의 블랜트의 경우 가공성에 다소 문제가 있고 가격이 높아 사용에 한계가 있다.In addition, the blend of polycarbonate and ABS resin has a problem in processability and high price, there is a limit to use.
또한 폴리프로필렌 수지등에 무기물을 충진할 경우 내열성은 향상되나 충진량에 비해 내열성 향상효과가 떨어지며 내충격성이 저하되는 단점이 있다.In addition, when the inorganic material is filled in the polypropylene resin, the heat resistance is improved, but the effect of improving heat resistance is lowered and the impact resistance is lowered compared to the filling amount.
최근 내열성을 향상시키는 가장 바람직한 방법으로서 말레이미드계 화합물의 이용이 점차 확대되고 있다.In recent years, the use of a maleimide type compound is gradually expanding as the most preferable method of improving heat resistance.
즉, 일본국 특허 소58-206657, 소63-162708등에서는 말레이미드 화합물과 방향족 비닐 및 시안화 비닐화합물과 공중합한 후 고무함유 종합체와 혼합하여 사용하는 방법이 제안되었으나 일반적인 유화 중합을 이용할 경우 말레이미드 화합물의 중합 반응속도가 빨라 중합초기에 말레이미드 함량이 높은 공중합체가 생성되어 높은 유리전이온도를 갖는 화합물 과다로 인해 내열성은 향상되난 내충격성 및 가공성이 저하된다.In other words, Japanese Patent Nos. 58-206657 and 63-162708 have proposed a method of copolymerizing maleimide compounds with aromatic vinyl and vinyl cyanide compounds and mixing them with rubber-containing composites. Due to the high polymerization reaction rate of the mid compound, a copolymer having a high maleimide content is formed at the beginning of the polymerization, and the impact resistance and processability of which the heat resistance is improved are reduced due to the excessive compound having a high glass transition temperature.
또한 중합된 라텍스의 응고과정에서 응고온도를 상승시켜 제조공정이 복잡해지고 생산 효율이 떨어지는 단점이 있다.In addition, there is a disadvantage in that the manufacturing process is complicated and the production efficiency is lowered by increasing the solidification temperature in the solidification process of the polymerized latex.
또한 미국 특허 4757109호의 경우 방향족 비닐 및 시안화비닐 화합물과 말레이미드 화합물을 투입하여 내열성 수지를 제조하는 방법이 제안되었으나 이 또한 제조공정이 복잡하고 말레이미드 화합물의 함량을 중량시키는데 한계가 있어 고내열성 수지의 제조가 어렵다.In addition, in the case of US Patent 4757109, a method of preparing a heat resistant resin by adding an aromatic vinyl, vinyl cyanide compound, and maleimide compound has been proposed, but this process is also complicated and has a limitation in weighting the content of the maleimide compound. Difficult to manufacture
일본국 특허 소63-235350의 경우 방향족 비닐화합물, 시안화 비닐 화합물 및 말레이미드 화합물을 연속적으로 투입하는 방법이 제안되었으나 이 또한 내충격성은 우수하나 고내열성을 얻는데 한계가 있다.Japanese Patent No. 63-235350 proposes a method of continuously adding an aromatic vinyl compound, a vinyl cyanide compound and a maleimide compound, but this also has excellent impact resistance but has a limit in obtaining high heat resistance.
본 발명자는 상기의 문제점을 해결하여 고내열성을 유지하면서 내충격성이 우수한 수지제조를 위하여 실험한 결과 방향족 비닐단량체 30∼60 중량부, 시안화 비닐 단량체 10∼25중량부 및 말레이미드 단량체15∼60중량부를 사용 중합을 행하는 데 있어서 단량체 투입방법, 유화제 및 이온 교환수의 사용량 및 투입 시기를 조절하여 라텍스 입자크기가 다른 두종류의 말레이미드 종합체를 제조하고 두 라텍스를 일정비율로 블렌딩한 것을 사용하여 최종 내열 내충격성 수지 조성물을 제조할 수 있음을 알게되어 본 발명을 완성하였다.The present inventors have solved the above problems to maintain a high heat resistance while experimenting for the production of a resin having excellent impact resistance, 30 to 60 parts by weight of aromatic vinyl monomer, 10 to 25 parts by weight of vinyl cyanide monomer and 15 to 60 weight of maleimide monomer In the polymerization process, two kinds of maleimide composites having different latex particle sizes were prepared by adjusting the monomer input method, the emulsifier and the ion exchange water, and the timing of the input. It was found that the final heat resistant impact resistant resin composition can be completed to complete the present invention.
이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명에서는 입자크기가 다른 두 종류의 말레이미드 중합체 라텍스를 제조하고 두 종류의 라텍스를 30:70∼70:30으로 블렌팅하고 응집건조하여 분말 형태의 최종 말레이미드 종합체를 제조한다.In the present invention, two types of maleimide polymer latexes having different particle sizes are prepared, and two types of latexes are blended at 30:70 to 70:30 and coagulated and dried to prepare a final maleimide aggregate in powder form.
제조된 말레이미드 중합체15∼70중량부를 고무함량 40%, 고무입자크기 1800∼2800Å으로 이루어진 고무함유 스틸렌계 중합체 30∼55중량부 및 방향족 비닐-시안화 비닐 중합체 35중량부 이하와 혼합하여 최종 내열 내충격 수지를 제조한다.15 to 70 parts by weight of the prepared maleimide polymer is mixed with 30 to 55 parts by weight of a rubber-containing styrene polymer composed of rubber content of 40%, rubber particle size of 1800 to 2800Å and 35 parts by weight or less of an aromatic vinyl-vinyl cyanide polymer Prepare a resin.
이하 본 발명에서 제조되는 말레이미드 중합체에 대하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the maleimide polymer prepared in the present invention will be described in more detail.
말레이미드 중합체 라텍스 I은 중합 1단계 반응에서 단량체 사용량의 15∼30%, 이온교환수 사용량의 30∼60% 및 유화제 사용량의 20∼50%를 반응계 내에 투입하여 중합을 개시하고 중합개시 1∼2시간 후 단량체 잔량, 유화제 사용량의 50∼70% 및 이온교환수 사용량의 20∼40% 혼합액을 연속적 또는 간헐적으로 5∼10시간 투입하여 2단계 중합반응을 진행하고 단량체 혼합물 투입환료후 유화제 및 이온교환수 잔여량을 일괄 투입하여 1800∼2500Å의 입자크기를 갖는 말레이미드 라텍스 I를 제조하며, 중합전사용 이온교환 수량의 60∼90% 및 유화제량의 70∼95%을 일괄투입한 후 시안화비닐 단량체량의 10∼2%를 제외한 단량체 혼합물 전량을 4∼8시간에 걸쳐 연속적으로 반응기에 투입하여 중합을 진행시키고 단량체 투입완료후 이온교환수, 유화제 및 시안화 비닐 단량체 잔량 혼합물을 1∼3시간 연속적으로 투입하여 500∼1200Å의 입자크기를 갖는 중합체 라텍스 Ⅱ를 제조하며 중합체 라텍스 I 및 II 를 30:70∼70:30으로 라텍스상 블렌딩한 후 응집건조하여 분말상태로 제조한다.The maleimide polymer latex I starts the polymerization by injecting 15-30% of the monomer amount, 30-60% of the ion-exchanged water amount and 20-50% of the emulsifier amount in the reaction system in the first stage of the polymerization. After 2 hours, the remaining amount of monomer, 50 to 70% of the amount of emulsifier and 20 to 40% of the amount of ion exchanged water are continuously or intermittently added for 5 to 10 hours to proceed the two-step polymerization reaction. The remaining amount of water was added in a batch to prepare maleimide latex I having a particle size of 1800 to 2500 kPa, in which 60 to 90% of the amount of ion exchanged for polymerization and 70 to 95% of the amount of emulsifier were added in a batch, and the amount of vinyl cyanide monomer The total amount of the monomer mixture except 10 to 2% of the mixture was continuously introduced into the reactor for 4 to 8 hours to proceed with polymerization.After completion of the monomer addition, ion exchanged water, emulsifier and vinyl cyanide were added. After adding the remaining sieve mixture continuously for 1 to 3 hours to prepare a polymer latex II having a particle size of 500 ~ 1200Å, blending the latex phase of polymer latex I and II from 30:70 to 70:30 and coagulation drying to powder To manufacture.
본 발명에서 라텍스의 입자크기가 500Å이하에서는 내충격성은 저하되나 내열성이 우수하며, 2500Å 보다 큰 경우에는 내충격성은 우수하나 내열성이 저하되고 응집시 어려움이 있다.In the present invention, when the particle size of the latex is 500 kPa or less, the impact resistance is lowered, but the heat resistance is excellent. When the particle size of the latex is larger than 2500 kPa, the impact resistance is excellent but the heat resistance is lowered and there is difficulty in aggregation.
또한 최종 내열 내충격 수지를 제조하는데 고무함량 40%, 고무입경 1800∼2800Å의 곰부함유수지가 사용되는데 입자크기 1800Å미만의 고무함유수지를 사용할 경우 광택도는 우수하나 내충격성이 떨어지고 2800Å보다 큰 경우 내충격성은 우수하나 광택도가 떨어진다.In addition, 40% of rubber content and 1800∼2800Å of rubber-bearing resin are used to manufacture the final heat-resisting impact resin. When using rubber-containing resins with particle size less than 1800Å, the gloss is excellent, but the impact resistance is lower than 2800Å. Excellent in performance but poor in gloss.
또한 라텍스 입자크기 1200∼1800Å일 경우 내열성 및 내충격성 모두 양호하나 고내열성 또는 고내충격성을 만족하기 어렵다.In addition, when the latex particle size is 1200 to 1800Å, both heat resistance and impact resistance are good, but it is difficult to satisfy high heat resistance or high impact resistance.
본 발명에서 사용되는 말레이미드 화합물은 N-페닐말레이미드, 시클로 헥실 말레이미드 등이고 사용량은 15∼60 중량부이며, 보다 적절하기로는 20∼50중량부이다.The maleimide compound used in the present invention is N-phenylmaleimide, cyclohexyl maleimide, or the like, and the amount of use thereof is 15 to 60 parts by weight, more preferably 20 to 50 parts by weight.
말레이미드 화합물의 사용량이 15중량부미만에서는 원하는 내열성을 얻기 힘들며 60 중량부보다 큰 경우에는 내충격성 및 가공성이 떨어지고 중합 반응제가 어렵다.If the amount of the maleimide compound is less than 15 parts by weight, it is difficult to obtain desired heat resistance. If the amount of the maleimide compound is greater than 60 parts by weight, the impact resistance and processability are poor, and the polymerization reagent is difficult.
방향족 비닐계 화합물은 스티렌, α-메틸스티렌, α-에틸스티렌, o-에틸스티렌, p-에틸스티렌, 2,4-디메틸스티렌등이며 사용량이 30 중량부 미만일 경우 가공성이 떨어지며 60중량부 보다 큰 경우에는 말레이미드계 화합물 사용량저하로 원하는 내열성을 얻기 힘들다.Aromatic vinyl compounds are styrene, α-methylstyrene, α-ethylstyrene, o-ethylstyrene, p-ethylstyrene, 2,4-dimethylstyrene and the like. In this case, it is difficult to obtain desired heat resistance due to the decrease in the amount of the maleimide compound used.
본 발명에서 사용되는 시안화 비닐계 화합물은 아크릴로니트릴, 메타크릴로 니트릴, 에타그릴로 니트릴 등이며 사용량이 10 중량부 미만에서는 내충격성이 떨어지며 25 중량부 보다 큰 경우에는 라텍스 안정성이 저하되고 열안정성이 극히 저하된다.The vinyl cyanide compound used in the present invention is acrylonitrile, methacrylonitrile, etharylonitrile, and the like, and the amount of impact is less than 10 parts by weight of impact resistance, and greater than 25 parts by weight of latex stability is lowered and thermal stability This is extremely degraded.
본 발명에서는 유화제로서 알킬벤젠 슬폰산 또는 라우릴 황산의 나트륨염 또는 칼륨염을 단량체 100 중량부당 0.7∼2.5 중량부를 사용하며 0.7중량부 미만에서는 라텍스 안정성이 극히 저하되고 응고량 과다로 생산성이 저하되며, 2.5 중량부 보다 큰 경우에는 라텍스 안전성은 향상되나 응집시 문제가 있고 탈수 및 세척시 많은량의 물과 시간이 필요하며 또한 생산성이 저하된다.In the present invention, sodium salts or potassium salts of alkylbenzene sulfonic acid or lauryl sulfate as emulsifiers are used in an amount of 0.7 to 2.5 parts by weight per 100 parts by weight of monomer, and less than 0.7 parts by weight of latex stability is extremely lowered and productivity is reduced due to excessive coagulation amount. In case of greater than 2.5 parts by weight, latex stability is improved, but there is a problem in flocculation, a large amount of water and time are required for dehydration and washing, and productivity is reduced.
또한, 본 발명에서는 이온 교환수량이 단량체 100 중량부당 150∼250 중량부가 사용되며 이온교환수량이 150 중량부 미만에서는 라텍스 안정성이 떨어지며 이온교환수량이 250 중량부 보다 큰 경우에는 라텍스 안정성이 우수하나 생산성이 저하되는 단점이 있다.In addition, in the present invention, the amount of ion exchanged water is 150 to 250 parts by weight per 100 parts by weight of monomer, the latex stability is lower when the ion exchanged water is less than 150 parts by weight, the latex stability is excellent when the ion exchanged water is greater than 250 parts by weight This has the disadvantage of deteriorating.
본 발명에서 중합 촉매로는 과황산 칼륨 및 퍼옥사이트계 레독스 촉매 모두 가능하나 과황산 칼륨이 보다 적절하다.In the present invention, as the polymerization catalyst, both potassium persulfate and peroxite-based redox catalyst may be used, but potassium persulfate is more suitable.
또한 중합계의 PH는 5이하가 적절하며 보다 적절하기로는 1.5∼3.5가 좋다.In addition, the pH of the polymerization system is preferably 5 or less, more preferably 1.5 to 3.5.
또한 분자량 조절제로는 t-도데실 메르캅탄으로 단량체 100 중량부당 0.5 중량부 이하로 사용하며 보다 적절하기로는 0.1∼0.3 중량부가 좋다.In addition, as the molecular weight regulator, t-dodecyl mercaptan is used in an amount of 0.5 parts by weight or less per 100 parts by weight of monomer, and more preferably 0.1 to 0.3 parts by weight.
