Description
본 발명은 도장용 ABS수지 조성물에 관한 것으로, 더욱 상세하게는 코어가 고무질 중합체이고 쉘이 방향족 스티렌 단량체와 아크릴로니트릴 단량체의 공중합물로 이루어진 코어-쉘형의 공중합체를 사용하여 유동성, 내충격성 및 내열성을 저하시키기 않으면서 도장후 표면평편성, 즉 광택성을 향상시킬 수 있는 ABS수지 조성물에 관한 것이다.
The present invention relates to an ABS resin composition for coating, and more particularly, fluidity, impact resistance, and The present invention relates to an ABS resin composition capable of improving surface flatness after coating, that is, glossiness, without reducing heat resistance.
일반적으로 부타디엔(butadiene), 스티렌모노머(styrene monomer), 아크릴로니트릴(acrylnitrile)로 구성된 ABS수지는 내충격성 및 가공성이 좋고 기계적 강도가 우수하여 여러 가지 성형품에 널리 사용되고 있다. 그러나, ABS수지를 도장 등의 목적으로 용제처리하였을 때 표면 굴곡(요철)이 심하게 발생하여 도장특성 및 광택이 저하되어 외관품질에 불량을 야기시키기도 하고 이로 인해 도장작업이 이중으로 요구되어 생산성 저하 등의 문제요인이 되기도 한다.Generally, ABS resins composed of butadiene, styrene monomer, and acrylnitrile have been widely used in various molded products because of their excellent impact resistance and workability and good mechanical strength. However, when the ABS resin is solvent-processed for the purpose of painting, surface curvature (unevenness) is severely generated, resulting in poor coating quality and gloss, which may result in poor appearance quality. It can also be a problem.
또한, 도장(painting)용 ABS수지의 사용이 확대되면서 도장시 사용되는 용제 의 종류도 다양화하게 되었는데, 특히 용제 특성이 강한 용제에 의해 도장처리시에는 과량의 고무성분이 변형되어 수지표면의 요철이 심하게되고 도장후 페인트와 수지간의 접착표면이 불균일하게되어 도장특성이 급격하게 악화되는 문제점이 있다.In addition, as the use of ABS resin for painting has been expanded, the types of solvents used for painting have been diversified.In particular, when the coating process is performed by a solvent having strong solvent properties, an excessive rubber component is deformed and the unevenness of the resin surface is increased. This becomes severe and there is a problem in that the adhesion surface between the paint and the resin after the coating becomes uneven and the coating properties deteriorate rapidly.
따라서, 상기와 같은 도장시의 문제점을 해결하기 위한 방법으로 일본 특공평 7-47679호에서는 처리용제의 성분을 희석하거나 종류를 변경하여 고무성분의 손상을 방지하는 방법과 아크릴로니트릴(AN)의 함량이 높은 FREE SAN을 사용하여 고무성분의 손상을 방지하는 방법을 제안하였다. 그러나, 이 방법의 문제점은 희석용제 및 다른 용제를 사용하는 부분은 반드시 가혹한 용제를 재사용하여야 하기 때문에 사용자에게 불편함을 줄 뿐만 아니라 내화학성을 향상시키기 위하여 AN함량이 높은 FREE SAN을 사용하는 경우 g-ABS의 내화학성은 향상시키기 않기 때문에 ABS 전체적으로도 내화학성 개선에 의한 광택향상은 달성하지 못하였다.
Therefore, Japanese Patent Application Laid-Open No. 7-47679 discloses a method for preventing damage to rubber components by diluting or changing the type of the treatment solvent as a method for solving the above problems in coating. A method of preventing damage to rubber components by using free SAN having a high content is proposed. However, the problem with this method is that it is not only inconvenient for the user because the diluent solvent and the part using other solvents must reuse harsh solvents, but when using a free SAN having high AN content to improve chemical resistance g -Since the chemical resistance of ABS is not improved, the gloss improvement by chemical resistance improvement was not achieved in ABS as a whole.
본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 코어가 고무질 중합체이고 쉘이 방향족 스티렌 단량체와 아크릴로니트릴 단량체의 공중합물로 이루어진 코어-쉘 형의 공중합체를 사용하여 유동성, 내충격성 및 내열성을 저하시키지 않고 도장특성이 우수하여 도장용 용도에 적합한 ABS수지 조성물을 제공하는 것이다.
An object of the present invention is to solve the conventional problems as described above, using a core-shell type copolymer consisting of a copolymer of an aromatic styrene monomer and an acrylonitrile monomer, the core is a rubbery polymer, the fluidity, The present invention provides an ABS resin composition having excellent coating properties without deteriorating impact resistance and heat resistance.
즉, 본 발명은 고무질 중합체의 평균입자 크기가 0.2∼0.5㎛인 g-ABS수지(A.1) 40∼60중량부와 고무질 중합체의 평균입자 크기가 0.08∼0.2㎛인 g-ABS 수지(A.2) 40∼60중량부로 구성된 입자직경이 상이한 2 종류의 g-ABS수지 10∼50%; (B) SAN수지 90 내지 50중량%; 및 (C) 코어가 고무질 중합체이고 쉘이 방향족 비닐계 단량체와 시안화비닐단량체의 공중합물로 이루어진 코어-쉘형 공중합체로 (A)+(B)전체에 대하여 0.1∼2.0중량%로 이루어진 것을 특징으로 하는 도장 밀착성이 우수한 ABS수지 조성물에 관한 것이다.
That is, the present invention provides 40-60 parts by weight of g-ABS resin (A.1) having an average particle size of rubber polymer of 0.2-0.5 μm and g-ABS resin having an average particle size of 0.08-0.2 μm of rubber polymer (A .2) 10 to 50% of two kinds of g-ABS resins having different particle diameters composed of 40 to 60 parts by weight; (B) 90 to 50% by weight of the SAN resin; And (C) a core-shell copolymer comprising a core of a rubbery polymer and a shell of a copolymer of an aromatic vinyl monomer and a vinyl cyanide monomer. The present invention relates to an ABS resin composition having excellent paint adhesion.
이하, 본 발명의 구성을 이루는 (A),(B),(C) 각 성분에 대하여 상세히 설명하면 다음과 같다.Hereinafter, each component (A), (B) and (C) constituting the present invention will be described in detail.
본 발명의 구성성분 (A)중 먼저, (A.1)인 g-ABS수지는 아크릴고무에 아크릴로니트릴 및 스티렌을 사용하여 아크릴로니트릴,스티렌 공중합을 행하며 동시에 아크릴고무로의 그라프트 공중합 반응을 행하는 방법으로 제조되는 것으로, 고무질 중합체의 평균입자크기는 0.2∼0.5㎛인 것이다. 또한, (A.2)의 g-ABS수지도 상기 (A.1)과 그 제조방법은 동일하나 고무질 중합체의 평균입자크기를 (A.1)보다 작은 0.08∼0.2㎛범위의 것을 사용한 것이다.Among the components (A) of the present invention, first, the g-ABS resin (A.1) performs acrylonitrile and styrene copolymerization using acrylonitrile and styrene on acrylic rubber and simultaneously graft copolymerization reaction with acrylic rubber. The average particle size of the rubbery polymer is 0.2 to 0.5 mu m. In addition, g-ABS resin of (A.2) is the same as (A.1) and the manufacturing method of the same, but the thing of the range of 0.08-0.2 micrometer which is smaller than the average particle size of (A.1) of a rubbery polymer is used.
본 발명에서 사용되는 성분 (A)는 상기와 같이 고무입자 직경이 서로 상이한 (A.1)과 (A.2)를 혼합하는데 이는 소입경고무의 (A.2)를 중입경고무의 (A.1)과 혼합하여 사용함으로써 사출성형시 수축방지 효과가 있을 뿐만 아니라 용제처리에 따른 배향된 고무의 변형을 최소화함으로써 용제처리후의 표면상태를 평평하게 하여 도장밀착성을 향상시킬 수 있게된다.Component (A) used in the present invention mixes (A.1) and (A.2) of rubber particle diameters different from each other as described above. By mixing with .1), it not only has an effect of preventing shrinkage during injection molding but also minimizes deformation of the oriented rubber resulting from solvent treatment, thereby making it possible to flatten the surface state after solvent treatment and to improve paint adhesion.
본 발명의 구성성분(B)인 SAN 수지는 현탁중합 또는 괴상중합법으로 중합가능하나 중합공정에 첨가되는 첨가제의 함량이 적고 겔 발생이 적은 괴상중합법으로 제조된 SAN 수지를 사용하는 것이 바람직하다. 이는 중합공정에 첨가되는 첨가제의 함량이 많을수록 사출성형품에 가스불량과 같은 외관불량을 발생하기 쉽고, SAN 수지에 겔이 포함되어 있을 경우에는 최종 성형품의 표면에 돌출되어 성형품의 품질을 저하시키는 문제점이 있기 때문이다.The SAN resin, which is the component (B) of the present invention, may be polymerized by suspension polymerization or bulk polymerization, but it is preferable to use a SAN resin prepared by a bulk polymerization method with a small amount of additives added to the polymerization process and low gel generation. . This is because the higher the amount of additives added to the polymerization process, the more likely to cause appearance defects such as gas defects in the injection molded article, and when the gel is contained in the SAN resin, it protrudes on the surface of the final molded article and degrades the quality of the molded article. Because there is.
SAN(B)수지의 구성은 스티렌 65∼78중량부, 아크릴로 니트릴 35∼22중량부로 구성되고, 중량평균 분자량이 8만∼20만 정도인 것이 바람직하다. 이는 중량평균 분자량이 8만 미만인 경우에는 내충격성이 현저히 저하되어 바람직하지 못하고, 중량평균분자량이 20만을 초과하는 경우에는 유동성이 현저히 저하되어 사출성형시에 미성형, 가스발생 불량 등을 야기할 수 있기 때문이다.The SAN (B) resin is composed of 65 to 78 parts by weight of styrene and 35 to 22 parts by weight of acrylonitrile, and preferably has a weight average molecular weight of about 80,000 to 200,000. This is undesirable because the impact resistance is significantly lowered when the weight average molecular weight is less than 80,000, and when the weight average molecular weight exceeds 200,000, the fluidity is significantly lowered, which may cause unmolding and poor gas generation during injection molding. Because there is.
본 발명의 구성성분(C)는 코어가 고무질 중합체이고, 쉘이 방향족 비닐계단량체의 공중합물로 이루어진 코어-쉘 형태의 공중합체로 고무질 중합체 25 내지 70중량부에 방향족 비닐계 단량체 40 내지 90중량부와 시안화비닐계 단량체 60 내지 10중량부의 단량체 혼합물 75 내지 30중량부를 그라프트시킨 공중합체이다.Component (C) of the present invention is a core-shell type copolymer in which the core is a rubbery polymer and the shell is a copolymer of an aromatic vinylic monomer, and the rubber vinyl polymer is 25 to 70 parts by weight of the aromatic vinyl monomer 40 to 90 parts by weight. It is a copolymer grafted 75-30 weight part of monomer mixtures with 60-10 weight part of vinyl cyanide monomers.
구성성분(C)에 사용되는 고무질 중합체는 실리콘계 고무, 디엔계 고무, 에틸렌계 고무 및 에틸렌/프로필렌/디엔 단량체의 3원 공중합체 고무로 이루어진 군으로부터 1종 이상 선택될 수 있으며, 바람직하게는 실리콘계 고무이다.The rubbery polymer used in component (C) may be selected from the group consisting of silicone rubbers, diene rubbers, ethylene rubbers and ternary copolymer rubbers of ethylene / propylene / diene monomers, preferably silicone It's rubber.
고무질 중합체의 고무입자의 평균입경은 10∼500μ인 것이 사용될 수 있으 며, 바람직하게는 200∼400μ의 것이다. 이때, 평균입경이 10μ미만이면 충격보강 효과가 별로없고, 500μ을 초과하면 적절한 형태학적 조절을 통한 충격보강 향상 및 도장 향상효과가 기대되지 않는다.The average particle diameter of the rubber particles of the rubbery polymer may be used is 10 to 500μ, preferably 200 to 400μ. At this time, if the average particle size is less than 10μ impact reinforcing effect is not very much, if it exceeds 500μ is not expected to improve the impact reinforcement and coating through the appropriate morphological control.
본 발명에서 구성성분(C)의 제조에 사용되는 고무질 중합체의 함량은 구성성분(C)100부에 대하여 25 내지 70중량부가 바람직하고, 더욱 바람직하게는 35 내지 60중량부이다. 고무질 중합체의 함량이 25중량부 미만이면, 경도, 인장강도, 굴곡강도와 같은 내열특성은 향상되지만 내충격성 및 도장특성이 급격히 저하되며 70중량부를 초과하면 내충격성은 우수하나 생산성이 저하되고 수지 조성물의 강도가 떨어지는 단점이 있다.The content of the rubbery polymer used in the preparation of the component (C) in the present invention is preferably 25 to 70 parts by weight, more preferably 35 to 60 parts by weight based on 100 parts of the component (C). When the content of the rubbery polymer is less than 25 parts by weight, the heat resistance properties such as hardness, tensile strength, and flexural strength are improved, but the impact resistance and coating properties are drastically lowered. When the rubber polymer content is more than 70 parts by weight, the impact resistance is excellent, but the productivity is lowered. There is a disadvantage of falling strength.
구성성분(C)에 사용되는 비닐계 단량체는 스티렌, p.t-부틸스티렌, 알파-메틸스티렌, 베타-메틸스티렌, 비닐크실렌, 모노클로로스티렌, 디클로로스티렌, 디브로모스티렌, 클로로스티렌, 에틸스티렌, 비닐나프탈렌, 디비닐벤제등과 같은 방향족 비닐계 단량체와 아크릴로니트릴, 메타크릴로니트릴, 에타크릴로니트릴등과 같은 시안화 비닐 단량체가 사용될 수 있으며, 더욱 바람직하게는 스티렌, 알파-메틸스티렌, 아크릴로니트릴이다.Vinyl monomers used in component (C) include styrene, pt-butylstyrene, alpha-methylstyrene, beta-methylstyrene, vinylxylene, monochlorostyrene, dichlorostyrene, dibromostyrene, chlorostyrene, ethyl styrene, Aromatic vinyl monomers such as vinylnaphthalene, divinylbenze, and vinyl cyanide monomers such as acrylonitrile, methacrylonitrile, ethacrylonitrile, and the like may be used, and more preferably styrene, alpha-methylstyrene, and acryl.
