Description

방화 퍼티 조성물Fireproof putty composition

본 발명은 방화 조성물의 개량에 관한 것으로 상온에서 불건성의 비가교 방화 퍼티 조성물에 관한 것이다.The present invention relates to improvements in fire protection compositions and to undry, noncrosslinked fire protection putty compositions at room temperature.

일반적으로 상온에서 불건성인 퍼티 상 조성물은 토목, 건축, 기타 전기, 자동차 등의 분야에서 있어 벽, 마루 등의 관통부의 공극을 충전 하든지 또는 기밀성, 수밀성을 유지하는 목적으로 사용되고 있다.In general, putty phase composition that is undry at room temperature is used in the fields of civil engineering, construction, other electricity, automobiles, etc. to fill voids of penetration parts such as walls and floors, or to maintain airtightness and watertightness.

그리하여 이와 같은 방화 퍼티 조성물로서는 불연 또는 난연성의 유기질 바인더를 기체로 하여 이에 수산화알루미늄 등의 무기 충전제, 3 산화 안티몬, 인화합물 등의 난연제 및 보강 섬유를 첨가하여 혼화물로서 출현 되었다.Thus, as such a fireproof putty composition, an inorganic filler such as aluminum hydroxide, a flame retardant such as antimony trioxide, or a phosphorus compound, and reinforcing fibers were added to the non-flammable or flame-retardant organic binder as a gas and appeared as a blend.

그러나 이와 같은 퍼티 조성물은 방화용으로서는 그 목적을 달성할 수 있으나 유연성이 없으므로 작업성이 곤란함과 동시에 경시 변화를 일으키므로 방치하면 형상이 변화하는 형태 안정성이 뒤떨어진 것이었다.However, such a putty composition can achieve its purpose as a fire protection, but since it is inflexible, it is difficult to work and at the same time causes a change over time.

본 발명은 이와 같은 결점을 개선하기 위하여 예의 연구한 결과 방화성은 물론 작업성 및 형태 유지성에 뛰어난 방화 퍼티 조성물을 발명한 것이다. 즉 본발명은 상온에서 액상의 클로로프렌 계 중합체 100 중량부에 클로로프렌 고무 1~35중량부, 수화수를 갖는 물 불용성 무기 충전재 200~600중량부 및 내열성 섬유 15~100중량부를 혼화 시킨것이다.The present invention has invented a fire retardant putty composition excellent in fire resistance as well as workability and shape retention as a result of intensive studies to improve such drawbacks. That is, the present invention is a mixture of 1 to 35 parts by weight of chloroprene rubber, 200 to 600 parts by weight of water-insoluble inorganic filler having hydrated water, and 15 to 100 parts by weight of heat resistant fiber at 100 parts by weight of liquid chloroprene polymer at room temperature.

본 발명은 특히 클로로프렌 고무로서 미가황의 것을 배합 함으로써 뛰어난 탄성과 신성을 부여 할 수 있음과 동시에 난연성이 있으므로 방화 특성을 향상 시킬 수 있는 것이다. 즉 탄성을 부여 함으로써 본 발명 조성물의 형상의 안정성이 증대하며 외력을 가한다 하여도 변형하는 일이 없는 저항성을 갖는다. 또 신성을 부여 함으로써 작업성을 극히 용이하게 할 수가 있다. 그리고 신성에 대하여는 다른 고무 예를 들면 부틸 고무, 에틸렌, 프로필렌 고무등도 뛰어나지만 이들 고무는 내화특성이 떨어지므로 방화용 퍼티로서 이용하기 어렵다.In particular, the present invention is capable of imparting excellent elasticity and ductility by blending unvulcanized chloroprene rubbers, and at the same time, improving fire resistance. That is, by providing elasticity, stability of the shape of the composition of the present invention increases, and even if an external force is applied, it is resistant to deformation. In addition, workability can be made extremely easy by giving divinity. In addition, the rubber is excellent in other rubbers such as butyl rubber, ethylene, propylene rubber, etc., but these rubbers are difficult to use as fire putty because they are inferior in fire resistance.

그리고 본 발명에 있어 상온에서 액상의 클로로프렌 계 중합체와는 상온(25℃)에서 점도 10,000~20,000CPS 바람직하기는 40,000~120,000의 범위로서 분자량 1,000~6,000의 미가황의 클로로프렌 액상 단독 중합체 또는 클로로프렌계 액상 공중합체를 말하는 것으로 분자 말단에 관능기를 갖고 안갖고는 불문이다. 그리고 클로로프렌계 공중합체로서는 클로로프렌과 공중합체가 되는 모노마 예를 들면 스틸렌, 메타크릴산메틸, 아크릴로니트릴, 1,3-부타디엔, 이소프렌 등의 비닐화합물이나 공액 디엔 화합물이 사용된다.In the present invention, a liquid chloroprene-based polymer at room temperature and a viscosity of 10,000-20,000 CPS at room temperature (25 ° C.), preferably in the range of 40,000-120,000, are unvulcanized chloroprene liquid homopolymers having a molecular weight of 1,000-6,000, or chloroprene-based liquid air. It refers to coalescence, regardless of whether it has a functional group at the end of the molecule. As the chloroprene copolymer, monomers which are copolymers with chloroprene, for example, vinyl compounds such as styrene, methyl methacrylate, acrylonitrile, 1,3-butadiene and isoprene or conjugated diene compounds are used.

본 발명에 있어 고체의 미가황클로로프렌 중합체를 첨가 함으로써 경시변화를 방지하며 보관 중에 경화 한다든지 또는 물성 변화를 일으키지 않도록 하였으며 그 성상은 10~35℃의 통상 사용하는 온도 범위에 있어 1년간 이상 방치하여도 거의 결정화 하는 일이 없는 지결정화형이며 또 무니점도의 변화가 없는 것이다. 이 첨가량은 전기 액상 클로로프렌계 중합체 100중량부에 대하여 1~35중량부, 바람직하기는 10~20중량부가 좋다. 그 이유는 1중량부 미만인 경우는 그 효과가 거의 없으며 또 35중량부를 넘으면 반대로 작업성이 저하하여 퍼티 성성으로 양호한 퍼티를 얻을 수가 없다.In the present invention, the addition of a solid unvulcanized chloroprene polymer prevents changes over time and does not cause curing or changes in physical properties. The properties are left at a temperature range of 10 to 35 ° C. for at least one year. It is a geocrystallization type that hardly crystallizes, and there is no change in Mooney viscosity. This amount is 1 to 35 parts by weight, preferably 10 to 20 parts by weight with respect to 100 parts by weight of the liquid chloroprene polymer. The reason for this is that less than 1 part by weight has little effect, and if it exceeds 35 parts by weight, on the contrary, workability is deteriorated and a putty cannot be obtained with good putty properties.

또 본 발명에 있더 수불용성 무기 충전재 예를 들면 수화 알루미나 수화 마그네시아, 수화 규산칼슘을 첨가하는 것인데 특히 수화 알류미나(일반식 Al2O3, nH2O 단 n :

Figure kpo00001
~3)가 가장 유효하며 그 첨가량을 액상 클로로프렌계 중합체 100중량부에 대하여 200~600중량부, 바람직하기는 250~450중량부이다. 그리고 상기의 첨가량에 한정하는 이유는 이 범위 이외의 경우에는 퍼티 조성물로서 일체화한 양호한 퍼티를 얻을 수가 없기 때문이다.In addition, for example itdeo water-insoluble inorganic filler in the present invention would be to add a hydrated alumina, hydrated magnesia, hydrated calcium silicate, especially hydrated alryu Mina (general formula Al 2 O 3, nH 2 O stage n:
Figure kpo00001
3) is most effective and the addition amount is 200 to 600 parts by weight, preferably 250 to 450 parts by weight based on 100 parts by weight of the liquid chloroprene polymer. And the reason for limiting to the said addition amount is because the favorable putty integrated as a putty composition cannot be obtained in anything other than this range.

또 본 발명에 있어 내열성 섬유 예를 들면 유리섬유, 석면, 암면, 난연성 유기섬유를 첨가함으로써 기계적 성능을 향상 시키는 것인데 특히 방화성능, 퍼티성능 및 경제성의 점에서도 바람직하다. 또 그 첨가량은 액상 클로로프렌계 중합체 100중량부에 대하여 15~100 중량부, 바람직하기는 25~60 중량부 이다. 이 첨가량에 한정한 이유는 15 중량부 미만의 경우에는 충분한 보강효과를 얻지 못하며 또 100 중량부를 넘은 경우에는 너무 굳어져서 작업성을 크게 저해한다.In addition, in the present invention, the mechanical performance is improved by adding heat-resistant fibers such as glass fibers, asbestos, rock wool, and flame retardant organic fibers, which is particularly preferable in terms of fire performance, putty performance and economy. In addition, the addition amount is 15-100 weight part with respect to 100 weight part of liquid chloroprene type polymers, Preferably it is 25-60 weight part. The reason for this addition amount is that when less than 15 parts by weight, a sufficient reinforcing effect is not obtained, and when it exceeds 100 parts by weight, it becomes too hard to significantly impair workability.

또한 본 발명에 있어는 탄산칼슘, 클레이 등의 필터, 3 산화 안티몬, 함 인화합물 등의 난연제를 첨가하여도 무방하다.In the present invention, a flame retardant such as a filter such as calcium carbonate or clay, an antimony trioxide, or a phosphorus containing compound may be added.
