Description

욕조용 시이트 조성물Sheet composition for bathtub

본 발명은 욕조용 시이트 조성물에 관한 것으로, 보다 상세하게는 합성수지 조성물의 알로이를 통하여 스크랩의 재활용을 가능케 한 욕조용 복층내지 적층시이트 조성물에 관한 것이다.The present invention relates to a sheet composition for a bath, and more particularly, to a multilayer-laminated sheet composition for a bath that enables recycling of scrap through an alloy of a synthetic resin composition.

욕조란 일반적으로, 목욕조, 세면조(대), 싱크조(대) 등을 포함하는 넓은 의미의 욕조(이하, 욕조라 한다)로서 욕조를 구성하는 시이트 제조시 일반적으로 스크랩 (SCRAP)이 발생한다.A bathtub is generally a bathtub (hereinafter referred to as a bathtub) in a broad sense including a bath, a basin, a sink, and the like, and generally a scrap (SCRAP) is generated when the sheet constituting the bathtub is manufactured. do.

스크랩이란 시이트 생산 중에 일정크기의 시이트로 자른 후 발생 하는 양옆의 모서리 부분, 일부분의 혼입화에 의하여 제품화되지 못한 것, 생산 초기에서부터 정품이 되기까지 발생하는 격외품을 통칭하는 것이다.Scrap is a generic term for extraneous goods that occur from the beginning of production to the genuine product, which are not commercialized by the incorporation of the edges on both sides of the sheet, partly mixed after cutting into sheets of sheet size during sheet production.

스크랩의 발생은 공정 중에서 20-40%정도이며 통상, 스크랩(SCRAP)은 재활용이 불가능 하여 폐기되는 바, 제품의 가격을 상승시킬 뿐 만 아니라, 그러한 폐기물로 인하여 환경을 해치는 문제점이 발생한다.The generation of scrap is about 20-40% in the process, and in general, scrap (SCRAP) is discarded because it is impossible to recycle, and not only raises the price of the product, but also causes the problem of harming the environment due to such waste.

상기한 바와 같은 문제점을 해결하기 위하여 고안된 본 발명은 욕조의 하층에 두 가지 수지가 혼합된 알로이를 사용하므로서 욕조 시이트 제조 시 발생하는 스크랩의 재활용이 가능한 복층 시이트를 제공하는데 있다.The present invention devised to solve the problems as described above is to provide a multi-layer sheet capable of recycling the scrap generated during the production of the bath sheet by using an alloy in which two resins are mixed in the lower layer of the bath.

본 발명의 다른 목적은 기존의 PMMA 와 ABS수지로 구성된 욕조 시이트에 비하여 물성이 보다 향상된 욕조 시이트를 제공하는데 있다.Another object of the present invention is to provide a bath sheet with improved physical properties compared to a bath sheet composed of conventional PMMA and ABS resin.

상기한 목적을 달성하기 위하여 본 발명의 아크릴 욕조용 합성수지 조성물은 하층에 PMMA 와 ABS의 알로이를 사용한다.In order to achieve the above object, the synthetic resin composition for acrylic bath of the present invention uses an alloy of PMMA and ABS in the lower layer.

일반적으로 아크릴 욕조는 2층으로 구성되어 상층은 PMMA(POLYMETHYL METHA ACRYLATE)로 구성되고, 하층은 ABS(ACRYLO BUTADIENE STYR ENE)으로 구성되어 있으며 그 각각은 중량 비로 상층이10~25%, 하층이 90~75%로 구성된 복층 구조이다.Generally, acrylic bath is composed of two layers, the upper layer is composed of PMMA (POLYMETHYL METHA ACRYLATE), and the lower layer is composed of ABS (ACRYLO BUTADIENE STYR ENE). It is a multilayer structure composed of ~ 75%.

본 발명에서는 하층에 PMMA와 혼합이 잘되는 ABS를 선정하여 둘 사이의 알로이를 형성하여 제조하며 그 혼합비는 1:9 ~ 9:1이며, 특히, 4:6 ~ 6:4가 바람직하다.In the present invention, by selecting the ABS well mixed with the PMMA in the lower layer to form an alloy between the two, the mixing ratio is 1: 9 ~ 9: 1, particularly, 4: 6 ~ 6: 4 is preferred.

이와 같이 PMMA 와 ABS의 알로이를 사용하게 됨으로서, 시이트를 성형시 발생하는 스크랩(상층인 PMMA 및 하층인 PMMA와 ABS의 알로이)을 다시 빻아서 하층의 PMMA와 ABS의 알로이층으로 재사용할 수 있는 것이다.By using the alloy of PMMA and ABS in this way, the scrap (alloy of the upper layer PMMA and lower layer PMMA and ABS) generated during forming the sheet can be ground again and reused as the alloy layer of the lower layer PMMA and ABS. .

본 발명에 의한 PMMA와 ABS의 알로이는 하층에만 적용된다. 상층은 내스크래치(SCRATCH) 성을 요구하는 바, 경도가 높은 것이 필요한 반면 하층은 충격완화나 하층면에 붙이는 불포화폴리에스테 보강재와의 접착 및 수축에 대한 완충작용을 하기 때문이다.The alloys of PMMA and ABS according to the invention apply only to the lower layer. Since the upper layer requires scratch resistance, it is necessary to have a high hardness, while the lower layer buffers against shock and adhesion and shrinkage with the unsaturated polyester reinforcing material attached to the lower layer.

일반적으로, 두가지의 수지를 혼합하여 사용하는 경우 물성이 떨어지는 것이 통상적이므로, 본 발명에 있어서, 적당한 ABS를 선택하는 것은 매우 중요하다.In general, when the two resins are used in combination, it is common to have poor physical properties, so in the present invention, it is very important to select a suitable ABS.

예컨대, PMMA와 ABS수지의 알로이에 있어서 용융지수가 차이가 나게 되면 2차 성형시 욕조표면에 매끄럽게 되지 못하는 단점을 갖게 된다. 따라서, 본 발명에 있어서, ABS 수지는 아크릴로 니트릴의 함량이 9-29 중량%이고, 용융지수가 0.5 내지 20인 것이 바람직하다.For example, if the melt index is different in the alloy of PMMA and ABS resin, there is a disadvantage in that the tub surface is not smoothed during the secondary molding. Therefore, in the present invention, it is preferable that the ABS resin has an acrylonitrile content of 9 to 29 wt% and a melt index of 0.5 to 20.

PMMA 와 ABS수지의 알로이는 PMMA나 ABS수지 단독에 비하여 인장변형에너지는 4배 ~ 8배 향상되어 진공 성형 시 제품성형이 잘되고 표면 평활성이 우수하며 물성의 저하 없이 스크랩이 30%까지 재활용 가능하다.The alloy of PMMA and ABS resin has 4 ~ 8 times higher tensile strain energy than PMMA or ABS resin alone, so that the product can be molded well in vacuum forming, the surface smoothness is excellent, and scrap can be recycled up to 30% without deterioration of physical properties.

종래의 아크릴욕조는 PMMA수지와 ABS의 복층 구조로 구성되어 시이트 제조중 발생하는 스크랩의 재활용이 불가능하였으나, 본 발명에 의하면 아크릴 욕조시이트의 하층에 PMMA 와 ABS의 혼합물을 사용함으로서 스크랩의 재활용이 가능하여 시이트 제조원가를 낮출 수 있는 바, 경쟁력이 있으며 폐기물을 줄임으로서 환경오염을 줄일 수 있는 것이다. 뿐만 아니라, 기존의 시이트 조성물에 비하여 인장변형 에너지가 향상되며, 욕조 성형시 표면상태가 보다 평활한 제품을 얻을 수 있다.Conventional acrylic baths are made of a multilayer structure of PMMA resin and ABS, which makes it impossible to recycle scrap generated during sheet production. However, according to the present invention, scrap can be recycled by using a mixture of PMMA and ABS in the lower layer of the acrylic bath sheet. This can lower sheet manufacturing cost, which is competitive and reduces environmental pollution by reducing waste. In addition, the tensile strain energy is improved compared to the conventional sheet composition, it is possible to obtain a product with a smooth surface state when forming a bath.
