Description
본 발명은 불포화폴리에스테르 수지(비스페놀type)에 저수축제와 경화제, 이형제, 안료, 유리섬유, 충진제, 산화방지제, 중합방지제 등을 배합하여 혼합하고 압출한 것을 기밀포장지로 감싸서 일정온도에서 일정기간 숙성시켜 열경화 성형이가능한 Bulk Molding Compaund로 조성하고 이를 계량하여 욕조금형에 넣고 고온고압이 유지되게 가열압착성형하여 제조되는 욕조의 제조방법에 관한 것이다.The present invention is a mixture of a low shrinkage agent, a curing agent, a release agent, a pigment, a glass fiber, a filler, an antioxidant, an polymerization inhibitor, and the like into an unsaturated polyester resin (bisphenol type), and the extruded, wrapped in an airtight wrapping paper and aged at a certain temperature for a certain period of time. The present invention relates to a manufacturing method of a tub manufactured by forming a Bulk Molding Compaund capable of thermosetting molding and weighing the same into a tub mold and thermocompression molding to maintain high temperature and high pressure.
종래의 욕조는 마불 또는 FRP제 욕조가 주로 제조되고 있으나 제법의 특수성으로 인해 수작업의 의존도가 높아 생산성이 떨어지는 문제점이 있었고 제품자체의 강도와 내구성이 비교적 낮고 질감과 색상도 고급스럽지 못한 결점이 있었다.Conventional baths are mainly made of Mabul or FRP baths, but due to the specificity of the manufacturing process, there is a problem of low productivity due to the dependence of manual work, and the strength and durability of the product itself is relatively low, and the texture and color are not high-quality.
본 발명은 이러한 종래의 결점을 개선하여 현대인의 기호에 맞는 질감과 색상을 유지할 수 있고 개구성 및 강도가 높은 고급욕조를 대량 생산할수 있게 제조방법을 개발한 것으로 이를 보다 상세히 설명하면 다음과 같다The present invention has been developed a manufacturing method to improve the above-mentioned shortcomings to maintain the texture and color according to the taste of modern people, and to mass-produce high-quality bathtubs with high openness and strength.

교반기에 넣고 40분 정포 교반하여 배합한 투 혼합기로 옮겨 불포화폴리에스테르수지량에 대하여 100-120%(중량비)정도가 되는 유리섬유를 넣고 5분 정도 혼합한후 압출기에 투입하여 직경 약 10cm정도 굵기로 압출시켜 압풀물을 나일론필름으로 피복하여 공기와 차단시킨후 30-40℃에서 3일정도 숙성시켜 열경화성형재료인 Bulk Molding Compaund를 제조하고(이하 BMC로 명칭함) 이를 욕조 1개성형에 소요되는 량(22 ∼24kg)으로 계량하여 재단한 다음 욕조금형에 투입하고 유압프레스를 작동하여 140℃ 온도와 100kg/㎠의 압력으로 가열압착성형하여 5-6분만에 탈형하여 제품을 얻는다.Put it into a stirrer and mix it with a 40-minute agitator and mix it with a two-mixer. Add 100-120% (weight ratio) of glass fiber to the amount of unsaturated polyester resin, mix it for about 5 minutes, and put it into the extruder. After extruded into a film, cover the puffs with nylon film, block it with air, and mature it at 30-40 ℃ for 3 days to produce a bulk molding compaund, a thermosetting molding material (hereinafter referred to as BMC). After measuring and cutting to the amount (22 ~ 24kg), put into a bath mold, operate the hydraulic press to hot-press molding at 140 ℃ temperature and pressure of 100kg / ㎠ to demould in 5-6 minutes to obtain the product.
한편, 본 발명은 유리섬유를 혼합할 때 별도로 준비한 칼라BMC 약간량을 같이혼합하면 칼라BMC의 투입량에 따라 외관이 마불무늬처럼되는 욕포를 만들수도 있게된다.On the other hand, when the glass fiber is mixed with a small amount of separately prepared color BMC when the glass fiber is mixed, the appearance may be made of a bath that looks like a marbling pattern depending on the amount of the color BMC.
이와 같이된 본 발명은 불포화폴리에스테르 수지를 충진제와 저수축제, 경화제,안료, 이형제 등과 배합하여 40분 정도 교반기에서 혼합하고 혼합기로 옳긴다음 혼합기에서 유리섬유를 투입하고 짧은 시간 혼합을 한 다음 압출기에 투입하여 압출하기 때문에 원료배합을 효과적으로 할 수 있으며 압출물은 직경 약 10cm정도되는 굵기로 압출하여 나일론 필름에 싸서 공기와 차단시킨 후 30-40℃에서 3일정도 숙성시키므로서 열경화 재료인 Bulk Molding Compaund를 조성할 수 있고 이로인해 혼합과정에서 유리섬유가 손상되지 않으면서 유리섬유와 폴리에스테르수지가 친화성을 발휘하게 되고 또한 유리섬유는 그 길이가 6-12mm정도로 가공되어서 혼합되므로 길고 짧은 유리섬유가 수지 내에 혼합되어 보강재의 소임을 충실하게 수행하는 효과를 낼 수 있다.In the present invention, the unsaturated polyester resin is blended with a filler, a low shrinkage agent, a curing agent, a pigment, a mold release agent, and the like, mixed in a stirrer for about 40 minutes, and then mixed with a mixer. Raw materials can be effectively mixed because it is injected and extruded. Extruded products are extruded to a thickness of about 10cm in diameter, wrapped in nylon film, blocked with air, and aged at 30-40 ℃ for 3 days. Compaund can be formed, and thus, glass fiber and polyester resin exhibit affinity without damaging the glass fiber in the mixing process. May be mixed in the resin to effect the faithfully performing the soaking of the reinforcing material.
따라서, 본 발명은 불포화폴리에스테르 수지를 열경화성형재료로 조성하여 가열압착성형으로 욕조를 제조하기 때문에 원료를 욕조 금형 내에 넣고 유압프레스로1 40"C온도와 100kg/㎠ 압력으로 가열압착하여 5-6분 이내에 성형을 완성할 수 있어서 기존의 마불 욕조나 FRP욕조와 같은 욕조에 비하여 생산성을 엄청나게 향상시킬 수 있고 이렇게 제조된 제품은 내열ㆍ내한ㆍ내약품성이 양호함은 물론이고 내구성과 강도가 뛰어날 뿐 아니라 생상과 질감이 변하지 않는 우수한 욕조를 만들 수 있고 색상도 다양하게 조성할 수 있어서 상품가치가 높은 고급욕조를 만들 수 있는 것이다.Therefore, in the present invention, since the unsaturated polyester resin is composed of a thermosetting molding material to prepare a bath by heat compression molding, the raw material is placed in a bath mold and heat-pressed at a pressure of 1 40 "C and 100 kg / cm 2 by a hydraulic press. Molding can be completed within 6 minutes, which greatly improves the productivity compared to conventional bathtubs such as Mabul baths or FRP baths. The manufactured products are excellent in heat resistance, cold resistance and chemical resistance, as well as excellent durability and strength. In addition, it is possible to make an excellent bathtub that does not change its appearance and texture, and to create a variety of colors to create a high-quality bathtub with high product value.
