불포화 폴리에스테르계 난연성 벌크 몰딩 컴파운드의 제조방법Method for preparing unsaturated polyester flame retardant bulk molding compound

본 발명은 난연성 벌크 몰딩 컴파운드의 제조방법에 관한 것으로, 보다 상세하게는 반응성을 갖는 브롬계 에폭시 타입의 난연제를 사용하고, 보강재로 유리섬유와 입도가 서로 상이한 수산화 알루미늄을 사용함으로써 블루밍 현상이 방지되고, 함침성, 외관, 성형성, 물성이 우수하며 특히 난연성이 매우 우수한 불포화 폴리에스테르계 난연성 벌크 몰딩 컴파운드의 제조방법에 관한 것이다.The present invention relates to a method for producing a flame retardant bulk molding compound, and more particularly, using a brominated epoxy-type flame retardant having a reactive, and by using aluminum hydroxide having a different glass fiber and particle size as a reinforcing material to prevent blooming phenomenon The present invention relates to a method for producing an unsaturated polyester flame retardant bulk molding compound having excellent impregnation, appearance, moldability, physical properties, and particularly excellent flame retardancy.

일반적으로 불포화 폴리에스테르 수지를 주성분으로 하고 무기 충진재, 섬유상 보강재, 경화제 및 기타 첨가제로 구성되어 있는 벌크 몰딩 컴파운드는 전기적 특성, 내열성등이 우수하여 퓨즈브레이크, 절연판, 코일봉지 제품과 같은 전기 절연재료외에도, 고강도, 치수안정성, 난연성등이 요구되는 정밀 전기 전자부품, 건축재료 등으로도 사용되고 있다. 그러나, 이와 같은 불포화 폴리에스테르계 벌크 몰딩 컴파운드는 일반 플라스틱제품과 마찬가지로 불에 접촉되면 연소되는 단점을 가지고 있어 난연성을 요구하는 전기, 전자부품이나 건축자재 분야에 적용시키기 위하여 난연처리를 하고 있다. 그러나, 난연성 향상을 위한 난연제와 무기 충진재의 함량이 증가함에따라 성형성 저하, 난연제의 미분산, 섬유상 보강재의 함침성 저하등이 단점으로 지적되고 있다.In general, bulk molding compounds, which consist mainly of unsaturated polyester resins and consist of inorganic fillers, fibrous reinforcements, hardeners and other additives, are excellent in electrical properties and heat resistance, so they can be used in addition to electrical insulation materials such as fuse brakes, insulation plates and coil encapsulation products. It is also used for precision electrical and electronic parts and building materials that require high strength, dimensional stability, and flame retardancy. However, such unsaturated polyester-based bulk molding compound has a disadvantage in that it burns when it comes into contact with fire as in general plastic products, and is subjected to flame-retardant treatment in order to be applied to electric, electronic parts or building materials fields requiring flame retardancy. However, as the content of the flame retardant and the inorganic filler for improving the flame retardancy increases, deterioration in moldability, fine dispersion of the flame retardant, impregnation of the fibrous reinforcement, etc. are pointed out as disadvantages.

국내공고특허 제 95-9156호에는 불포화 폴리에스테르 수지를 주성분으로 하고 표면처리된 중질 탄산칼슘, 유리섬유, 난연제 등을 첨가하여 인성이 향상되고 저수축효과를 가지며 UL94 V-O수준의 난연성을 갖는 벌크 몰딩 컴파운드를 제조하는 방법이 제안되어 있는데, 이러한 방법은 수지함량이 30중량%인 것에 비하여 회분함량이 너무 적기 때문에 UL94 V-O보다 가혹한 UL94 5V 및 국내 건축법규 등에 대해서는 단순하게 난연제 함량의 증가만으로는 충분한 난연효과를 기대할 수 없을 뿐만아니라 유리섬유의 함량이 많기 때문에 성형시 외관이 불량한 단점이있다.In Korea Patent No. 95-9156, bulk molding having unsaturated polyester resin as its main component and adding surface-treated heavy calcium carbonate, glass fiber, and flame retardant to improve toughness, low shrinkage effect and flame retardancy of UL94 VO level A method of preparing a compound has been proposed. Since this method has too little ash content compared to 30% by weight of resin, for the UL94 5V, which is harsher than UL94 VO, and domestic building codes, the increase in the flame retardant content is sufficient to provide a sufficient flame retardant effect. Not only can not be expected because of the high content of glass fiber has a disadvantage in appearance when molding.

또한, 일본 특개평 5-24583 에서는 비교적 작은 함량의 수지와 유리섬유 및 난연제를 혼합 사용한 제조방법을 제시하고 있다. 그러나, 이와 같은 방법에 있어서도 수지함량은 감소시키고 회분함량을 증가시키는 것에 의해서 난연 효과를 향상시키고 유리섬유 함량을 감소시킴으로써 외관특성이 향상된다는 장점이 있으나 자기 소화성 무기 충진재인 수산화 알루미늄의 함량이 너무 높기 때문에 충진재의 함침저하와 제품 성형시에 문제가 발생하고 난연제의 미분산에 의한 난연성의 불균일 문제, 브롬계 난연제에 의한 블루밍 현상 등이 단점으로 지적되고 있다.In addition, Japanese Patent Laid-Open No. 5-24583 proposes a manufacturing method using a mixture of a relatively small amount of resin, glass fiber and a flame retardant. However, even in such a method, the resin content is reduced and the ash content is increased, thereby improving the flame retardant effect and improving the appearance property by reducing the glass fiber content, but the content of aluminum hydroxide, which is a self-extinguishing inorganic filler, is too high. As a result, problems of impregnation of the filler and molding of the product occur, non-uniformity of flame retardancy due to undispersed flame retardant, and blooming phenomenon of bromine flame retardant are pointed out as disadvantages.

본 발명은 상기와 같은 문제점을 해결하고자 아이소 타입의 불포화 폴리에스테르 수지에 브롬계 반응성 에폭시 타입의 난연제 및 입도가 서로 상이한 수산화 알루미늄과 유리섬유를 사용함으로써 충진재의 함침성, 외관, 성형성, 물성등이 우수하며, 특히 난연성이 우수한 불포화 폴리에스테르계 벌크 몰딩 컴파운드의 제조방법을 제공하는 것이다.The present invention is to solve the problems described above by using a brominated reactive epoxy type flame retardant and aluminum hydroxide and glass fiber of different particle size in the unsaturated polyester resin of the iso type, impregnating, appearance, moldability, physical properties, etc. It is to provide a method for producing an unsaturated polyester-based bulk molding compound that is excellent in flame retardancy and particularly excellent in flame retardancy.

즉, 본 발명은 난연성 불포화 폴리에스테르계 벌크 몰딩 컴파운드의 제조에 있어서, 브롬계 반응성 에폭시 타입의 난연제를 수지 100중량부에 대하여 35 내지 55 중량부 사용하고, 입도가 각각 5 내지 10㎛ 및 40 내지 60㎛인 수산화 알루미늄을 250 내지 500 중량부 혼합 사용하고, 1/4 내지 3/4인치 유리섬유를 45 내지 85 중량부 사용하는 것을 특징으로 하는 난연성 불포화 폴리에스테르계 벌크 몰딩 컴파운드의 제조방법을 제공하는 것이다.That is, the present invention, in the production of flame-retardant unsaturated polyester-based bulk molding compound, using a brominated-based reactive epoxy type flame retardant 35 to 55 parts by weight relative to 100 parts by weight of resin, the particle size of 5 to 10㎛ and 40 to It provides a method for producing a flame-retardant unsaturated polyester-based bulk molding compound characterized by using a mixture of 250 to 500 parts by weight of aluminum hydroxide of 60 ㎛, and 45 to 85 parts by weight of 1/4 to 3/4 inch glass fiber. It is.

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

본 발명의 수지부는 점도가 25 내지 40포이즈이고 에스피아이(SPI)겔화 시간이 5 내지 25분인 아이소 타입의 불포화 폴리에스테르 수지로 전체 조성물에 대하여 10 내지 20중량%이다. 또한, 불포화 폴리에스테르 수지와 함께 열경화성 수지의 수축율을 개선시키기 위해 폴리스티렌계수지를 1 내지 6중량% 사용하여 수지부를 형성한다. 이때, 수지부의 함량이 너무 많은 경우에는 난연성이 저하될 수 있으며, 너무 작을 경우에는 유리섬유와 무기 충진재의 함침성이 저하되는 등의 문제점이 발생할 수 있다.The resin part of the present invention is an isotype unsaturated polyester resin having a viscosity of 25 to 40 poise and an SPI gelling time of 5 to 25 minutes, and is 10 to 20% by weight based on the total composition. In addition, in order to improve the shrinkage of the thermosetting resin together with the unsaturated polyester resin, the resin portion is formed by using 1 to 6% by weight of polystyrene resin. In this case, when the content of the resin part is too much, flame retardancy may be lowered, and when too small, problems such as impregnation of the glass fiber and the inorganic filler may occur.

강성의 향상과 동시에 난연성의 부여를 위하여 본 발명에서 사용되는 무기 충진재는 입도가 서로 상이한 수산화 알루미늄을 30 : 70 내지 70 : 30의 비율로 혼합하여 수지 100 중량부에 대하여 250 내지 500중량부가 사용된다. 수산화 알루미늄 입자의 크기는 1 내지 80㎛사이에서 여러 가지로 조합하여 사용하는 것이 바람직하고, 가장 바람직하게는 5 내지 10㎛ 및 40 내지 60㎛사이의 두 종류의 입자를 선택하여 사용하는 것이 수산화 알루미늄의 미함침 문제가 발생하지 않게된다.In order to improve rigidity and impart flame retardancy, the inorganic filler used in the present invention is mixed with aluminum hydroxide having different particle sizes at a ratio of 30:70 to 70:30, and 250 to 500 parts by weight is used with respect to 100 parts by weight of the resin. . The size of the aluminum hydroxide particles is preferably used in various combinations between 1 and 80 µm, and most preferably, two types of particles between 5 and 10 µm and 40 to 60 µm are selected and used. The impregnation problem does not occur.

난연제의 사용에 있어서, 일반적으로는 데카브로모다이페닐렌 옥사이드, 펜타브로모다이페닐 옥사이드, 펜타브로모 톨루엔등 브롬계 난연제가 많이 사용되나 반응성이 거의 없는 브롬계 난연제의 경우에는 블루밍 현상이 심하고 연소시 유해한 브롬가스가 발생하므로 본 발명에서는 에폭시 반응기를 갖는 브롬계 난연제를 단독 혹은 혼합하여 사용한다. 난연효과를 향상시키기 위하여 단순히 난연제의 함량을 증가시킬 경우에는 발연량이 증가하게 되므로 본 발명에서는 우수한 난연성을 나타내면서 발연량이 적은 35 내지 55중량부의 브롬계 에폭시 반응성 타입의 난연제를 사용하고, 난연제를 활성화시켜 난연 효과를 높이는 난연조제로서 삼산화 안티몬 등 금속화합물이 5 내지 15중량부 사용된다.In the use of flame retardants, brominated flame retardants such as decabromo diphenylene oxide, pentabromo diphenyl oxide, pentabromo toluene are generally used, but bromine flame retardants that are almost inactive have severe blooming and burned. Since harmful bromine gas is generated, the bromine flame retardant having an epoxy reactor is used alone or in combination. In order to improve the flame retardant effect, simply increasing the content of the flame retardant increases the amount of smoke, and thus, in the present invention, a flame retardant of 35 to 55 parts by weight of a bromine-based epoxy reactive type flame retardant exhibiting excellent flame retardancy and having a small amount of smoke is activated, 5 to 15 parts by weight of a metal compound such as antimony trioxide is used as a flame retardant aid to enhance the flame retardant effect.

보강재로 사용되는 유리섬유는 주로 유리 단섬유로 45 내지 85중량부가 바람직하며, 가장 바람직하게는 45 내지 65중량부이고, 섬유 길이는 1/4 내지 3/4인치이다.The glass fiber used as the reinforcing material is mainly short glass, preferably 45 to 85 parts by weight, most preferably 45 to 65 parts by weight, and the fiber length is 1/4 to 3/4 inches.

이형제로는 스테아린산아연과 같은 지방산계 금속화합물이 5 내지 15중량부 사용되고, 불포화 폴리에스테르를 경화시키기 위한 경화제로는 터셔리 부틸 퍼옥시 벤조에이트, 벤조일 퍼옥사이드 등의 퍼옥시드계 유기화합물이 1.5 내지 3.5 중량부 사용된다.As a release agent, 5-15 weight part of fatty acid type metal compounds, such as zinc stearate, are used, and as a hardening | curing agent for hardening unsaturated polyester, 1.5-peroxide organic compounds, such as tertiary butyl peroxy benzoate and benzoyl peroxide, are used. 3.5 parts by weight is used.

이외에 필요한 경우 습윤제, 증점제, 안료, 염료 등과 같은 첨가제를 사용할 수 있다.In addition, additives such as wetting agents, thickeners, pigments, dyes and the like may be used if necessary.

이하 본 발명을 실시예를 들어 더욱 자세히 설명하고자하나 본 발명이 하기 실시예에 의하여 제한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited by the following Examples.
