차량용 합성수지(세미 메탈릭) 마찰판의 제조방법Manufacturing Method of Semi-Metallic Friction Plate for Vehicle

본 발명은 합성수지를 결합제로 해서 성형되는 합성수지 마찰판의 성형시의 가스발생을 제거하는 것을 목적으로 한 차량용 합성수지(세미 메탈릭) 마찰판의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a synthetic resin (semi-metallic) friction plate for a vehicle for the purpose of eliminating gas generation during molding of a synthetic resin friction plate that is formed by using a synthetic resin as a binder.

근간 래진모울드, 세미모울드, 특수가공우븐 세미메탈릭 등 합성수지를 결합제로 한 차량용 합성수지 마찰판 제조가 널리 사용되어 제조되고 있지만 이 결합제로 사용되는 합성수지에는 내열강도가 우수한 "훼-롤" 수지가 사용되어 이 수지에 여러가지 특수재료를 배합시킨 것을 금형에 삽입하여 고온고압의 열프레스로 압축 성형하거나 혹은 처음부터 예비 압축성형한 후 소성가공하는 방법이 행해지고 있으나, 이 성형 공정 중에는 다음과 같은 이유로 인하여 가스제거 조작이 반드시 행하여지고 있다.Although the manufacture of synthetic resin friction plates for automobiles made of synthetic resins such as resin molds, semi-moulds, and specially processed woven semimetallics are widely used, the synthetic resins used in these binders are made of high-strength heat-resisting resins. Although various special materials mixed with resin are inserted into a mold, compression molding is performed by hot press at high temperature and high pressure, or preliminary compression molding is performed from the beginning, and then plastic processing is performed. This is always done.

즉 "훼-롤" 수지를 성형시에는 완전한 중합체의 성형품을 얻기 위해서 성형전에 "핵사민"을 6~15% 첨가하는 것이 통예로 되어 있으나 "핵사민"이 성형시에 있어서 가열 가압 성형 공정 중에 열로 이해 분해되어 저분자량의 "훼-롤" 수지와 가교반응하여 이 분해반응 중에 다량의 암모니아성 가스와 수분이 발생한다. 또 이와 동시에 휘발성분을 포함한 가스성분 등 기타가 발생하여 이들을 포함해서 보통 가스라고 하고 있음.In other words, in order to obtain a completely polymer-molded product during the molding of the roll-rolled resin, it is conventional to add 6 to 15% of nucleosamin before molding. It is decomposed into heat and crosslinks with a low molecular weight morph-rolled resin to generate a large amount of ammonia gas and water during this decomposition reaction. At the same time, other gas components including volatile components are generated and these are called ordinary gases.

이와 같이 발생한 가스를 수지가 열경화 하기 전에 제거하지 않으면 성형 중에 발생한 가스가 고여서 성형품 내부에 "흠집" "기공" "갈라짐"등이 발생 또한 성형품 내부에 고인 가스의 압력으로 인한 균열이 발생한다.If the generated gas is not removed before the resin is heat-cured, the gas generated during molding may accumulate, causing cracks, pores, and cracks in the molded part, and cracks may be generated due to the pressure of the accumulated gas inside the molded part. .

따라서 이와 같은 성형품이 차량용 마찰판으로 사용되면 제동시 제동력이 저하되고 최악의 경우에는 균열부분으로 마찰판의 결손, 탈락을 초래하고 충분한 제동력을 얻지 못한다.Therefore, when such a molded article is used as a friction plate for a vehicle, the braking force is lowered during braking, and in the worst case, it causes defects and dropouts of the friction plate as cracks and does not obtain sufficient braking force.

이상과 같은 결점을 없애기 위해서 가스빼기 조작이 이루어지고 있으나 이 조작을 하드라도 충분히 제거하지 못한다.The gas degassing operation is made to eliminate the above defects, but this operation cannot be sufficiently removed even if it is hard.

본 발명은 가스 흡착효과가 높은 충진체 중에서 가격이 싸고 배합할 때의 조작이 용이한 바-미크라이트와 활성탄소를 핵사민이 함유한 훼-롤 수지에 배합하여 가스발생이 없는 차량용 합성수지 마찰판을 얻게 한 것이다.The present invention is to obtain a synthetic resin friction plate for vehicles without gas generation by blending bar-microlite and activated carbon into the fe-roll resin containing nucleomin, which is easy to operate when formulated at low cost among the fillers having high gas adsorption effect. It is.

이하 본 발명의 실시예를 상세히 설명코져 한다.Hereinafter, embodiments of the present invention will be described in detail.

우선 바-미크라이트(비중 1.3 SiO237%, Al2O314%, Fe2O34.4%, MgO 24.6%, H2O 20%)를 고온 약 1500~2000℃에서 소성하여 다시 미입자상으로 가공한다. 다음 이것을 300~450℃의 온도로 8~10시간 가열해서 활성화 한 것과 800~900℃ 환원 분위기 중에서 부활된 미입자의 활성탄소 분과 5 : 1~10 : 1의 비로 균일하게 혼합분을 만들고 이 혼합물과 핵사민 함유의 훼-롤 수지와의 30 : 70 ~ 20 : 80의 비로 균일하게 혼합한 결합용 수지 조성분을 만든다.First, bar-microlight (specific gravity 1.3 SiO 2 37%, Al 2 O 3 14%, Fe 2 O 3 4.4%, MgO 24.6%, H 2 O 20%) was calcined at a high temperature of about 1500 ~ 2000 ℃ again to be fine particles Process it. Next, the mixture was activated by heating it at a temperature of 300 to 450 ° C. for 8 to 10 hours, and the mixture of activated carbon of fine particles regenerated in a reducing atmosphere of 800 to 900 ° C. and a ratio of 5: 1 to 10: 1 to make a uniform mixture. A resin composition for bonding is uniformly mixed in a ratio of 30:70 to 20:80 with a nusamine-containing ferol resin.

다음 상기 결합용 수지 조성분 60~95%에 대하여 철 또는 동분을 40 이내 첨가 후 성형시에 형빼기를 보다 원활하게 하기 위하여 스테아린산 또는 금속염 즉 스테아린산칼슘, 스테아린산마그네슘을 소량 첨가한다.Next, a small amount of stearic acid or metal salts, namely calcium stearate and magnesium stearate, is added to the bonding resin composition 60 to 95% in order to smooth out mold after forming iron or copper powder within 40.

이상에서 본 발명의 합성수지 마찰판용 수지가 제조된다.In the above, the resin for synthetic resin friction plates of the present invention is produced.

다음 이 발명품을 가지고 마찰판을 성형하는 경우에는 약 80℃의 금형에 혼합분을 삽입하고 즉시 윗금형을 닫고 그대로 가압하지 않고 100℃ 정도 달한 후 300~ 400kg/cm2의 압력을 가한 후 재차 금형온도를 160℃에 달하면서부터 소정시간 방치한 후 즉시 성형품을 금형으로 분리하면 목적한 차량용 합성수지제 마찰판이 제조된다.Next, in the case of forming a friction plate with this invention, insert the mixed powder into the mold at about 80 ℃, immediately close the upper mold, reach 100 ℃ without pressurizing as it is, and press the pressure of 300 ~ 400kg / cm 2 again, and then mold temperature again. When the molded article is separated into a mold immediately after being left for a predetermined time from reaching a temperature of 160 ° C., a friction plate for a synthetic resin for a vehicle is manufactured.

이때에 가스빼기 조작을 할 필요가 없는 것은 물론이다. 더욱 본 발명품 효과를 확인하기 위하여 실험결과를 명시하면 표 1과 같다.Of course, there is no need to perform the degassing operation at this time. In order to confirm the effect of the present invention, the results of the experiment are shown in Table 1.
