본 발명은 발포스폰지의 표면에 요입부와 돌기를 형성하여 지압효과를 얻을 수 있도록 한 지압매트의 제조방법 개량에 관한 것이다.The present invention relates to an improvement of a method for manufacturing an acupressure mat to form an indentation and a protrusion on a surface of a foam sponge to obtain an acupressure effect.

종래 본 출원인이 안출한 지압매트는 요입부와 돌기를 형성한 발포스폰지의 표면에 경도를 주기 위해 우레탄과 TDI 및 촉매인 스탄노우스옥토에이트를 혼합한 혼합액을 도포하고 건조하여서 되는 것이었다. 그러나 이는 건조과정에서 PPG와 TDI(톨루엔 디 이소시아네이트) 및 촉매제가 공기중의 수분과 반응으로 독가스가 발생되어 작업자의 인체에 유해함은 물론 능률적인 작업을 할 수 없었다. 뿐만 아니라 제품이 완성된 후에도 TDI의 독성이 완전 증발하지 않고 제품에 함유되어 사용시에 대기와의 접촉으로 잠재된 TDI의 독성이 증발하면서 악취가 발생되어 사용자의 머리를 아프게 하고 실내공기를 혼탁하게 하는 등의 단점이 있었다. 그리고 또다른 방법은 스폰지를 프레스로 압축시켜 150℃ 이상의 고온으로 숙성시켜 만든 매트가 있으나 이는 경도와 인장도가 약하여 얼마 사용하지 않아 깔아앉게 되는등 지압매트로서 부적합한 폐단이 있었다.Conventionally, the pressure-sensitive mat prepared by the present applicant was to apply and dry a mixed solution of urethane, TDI, and stannous octoate, which is a catalyst, to give hardness to the surface of the foamed sponge in which the indentation portion and the protrusion were formed. However, this caused the poisonous gas generated by the reaction of PPG and TDI (toluene diisocyanate) and the catalyst with moisture in the air, which is harmful to the human body of the worker and was unable to work efficiently. In addition, even after the product is finished, the toxicity of TDI is not completely evaporated, but it is contained in the product, and the toxic potential of TDI evaporates due to contact with the atmosphere when it is used, causing odors to hurt the user's head and cloud the indoor air. There was such a disadvantage. Another method is a mat made by compressing a sponge with a press to be aged at a high temperature of 150 ° C. or higher, but it has an unsuitable closed end as an acupressure mat, such as being hardly used due to its weak hardness and tensile strength.

본 발명은 이와 같은 점을 감안하여 TDI의 독성을 요입부와 돌기를 형성시키는 성형시에 수증기로서 숙성 중화시켜 악취를 제거하고 또한 경도가 우수하여 지압효과를 크게 얻을 수 있는 지압매트를 제조한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.In view of the above, the present invention is to manufacture the acupressure mat which neutralizes the toxicity of TDI as water vapor during molding to form the concave and protrusions, and removes the odor, and also obtains a high acupressure effect with excellent hardness. When described in detail based on the accompanying drawings as follows.

요입부(1)와 돌기(2)가 형성된 지압매트(3)를 형성함에 있어서 요입부(1)와 돌기(2)가 형성되지 않은 평면상의 발포스폰지에 포리올(PPG) 100부와 TDI 45부 스탄노우스옥토에이트 등의 촉매제 2부를 혼합한 혼합액을 골고루 투입시킨 다음 요입부(1)와 돌기(2)가 형성된 상, 하금형(4),(4')에 넣고 프레스로 압축시킨후 하부금형(4')에 뚫은 θ2 정도의 구멍(5)(5')을 통해 수증기를 통과시키고 수증기에 의해 80℃ 이상 온도가 상승될때까지 숙성시켜서 되는 것이다.100 parts of polyol (PPG) and 45 parts of TDI in a flat foamed sponge in which the indentation part 1 and the projection 2 are not formed in forming the acupressure mat 3 having the indentation part 1 and the projection 2 formed therein. A mixture of 2 parts of a catalyst, such as stannous octoate, is mixed evenly, and then put into the upper, lower molds (4) and (4 ') where the indentation part (1) and the projection (2) are formed and compressed by a press. The water vapor is passed through the holes 5 and 5 'of approximately θ2 drilled into the mold 4' and aged until the temperature rises above 80 ° C by water vapor.

또한 상, 하금형(4)(4')에 폴리우레탄을 도포한 포지를 깔고 동시에 성형하거나 또는 상, 하금형(4)(4')에 폴리우레탄을 도포한후 지압매트를 성형하면 지압매트의 표면에 포지 또는 폴리우레탄층이 일체로 형성된다.In addition, by placing a forge coated with polyurethane on the upper and lower molds (4) and (4 ') or molding at the same time, or by applying a polyurethane to the upper and lower molds (4) and (4'), the acupressure mat is molded. On the surface of the forge or polyurethane layer is formed integrally.

이와 같이 된 본 발명은 평판상의 발포스폰지에 포리올 100부와 TDI 45부 촉매제 2부로 혼합한 혼합액을 투입시켜 스폰지의 내부와 외면에 골고루 침투시킨 다음 요입부(1)와 돌기(2)가 형성된 상, 하금형(4)(4')에 넣고 프레스로 압착하면 혼합액으로 인해 경도가 우수하고 인장력이 좋은 지압매트가 얻어지게 되는바 상, 하금형(4)(4') 에서 프레스로 가압하는 과정에서 하부금형(4')에 뚫은 구멍(5)(5')을 통해 뜨거운 수증기를 약 80℃ 이상 될 때까지 통과시키면 상기한 혼합물이 수증기의 물과 화학반응을 일으켜 혼합물의 독성에 중화되므로 화학약품 냄새가 없어지고 혼합물이 응고되어 경도가 우수한 지압매트가 만들어 지는 것이다.In the present invention as described above, a mixture of 100 parts of polyol and 2 parts of TDI 45 parts of catalyst is added to a flat foamed sponge to infiltrate the inner and outer surfaces of the sponge evenly, and then the indentation part 1 and the projection 2 are formed. When pressurized into the lower mold (4) (4 ') and pressed with a press, a pressure-bearing mat having excellent hardness and tensile strength is obtained due to the mixed liquid. Passing hot steam through the holes (5) (5 ') in the lower mold (4') until it reaches about 80 ° C or more, the chemical mixture reacts with water in the water vapor and neutralizes the toxicity of the mixture. The chemical smell is eliminated and the mixture is solidified to produce a pressure-resistant mat.

이와 같은 방법에 의해 제작된 본 발명의 지압매트는 통상적인 이불과 같이 포지로 싸서 사용하면 되고 이때 요입부(1)에 공지의 자석을 부착시키면 지압효과와 더불어 자력의 효과도 동시에 얻을 수 있어 인체에 유익하다.The acupressure mat of the present invention produced by such a method may be used wrapped in a forge like a general futon, and when a known magnet is attached to the indentation part 1, the acupressure effect and the effect of magnetic force can be simultaneously obtained. Is beneficial.

그리고 포지를 싸지않고 금형에서 프레스 가압시 금형에 폴리우레탄을 도포한 포지를 먼저 깔고 가압하여 포지가 스폰지의 외면에 일체로 부착되도록 하여도 되며 또 금형에 폴리우레탄을 적정 두께로 도포한후 스폰지를 성형하면 매트 표면에 폴리우레탄 스킨층이 일체로 도포된 지압매트를 얻을 수 있는 것이다.And when press press on the mold without wrapping the forge, the forge coated with polyurethane on the mold may be laid first and then pressurized so that the forge is integrally attached to the outer surface of the sponge. When molded, a pressure-sensitive mat obtained by integrally applying a polyurethane skin layer to the mat surface can be obtained.

이와 같이 본 발명은 PPG, TDI 촉매를 혼합한 혼합물을 발포스폰지에 침투시켜 상하금형에서 가압 성형하므로서 지압매트를 형성항 것이므로 경도가 우수하여 지압효과가 매우 좋을뿐 아니라 장기간 사용하여도 종래와 같이 깔아 앉게되는 폐단이 없으며 또한 가압성형시 수증기를 침투시켜 혼합물과 화학반응을 일으키므로서 독성을 중화시켜 악취를 제거하므로 사용할 때 화학약품 냄새가 나지않아 종래와 같이 머리가 아픈 등의 폐단이 해소된 지압매트를 얻을 수 있는 효과가 있다.As described above, the present invention is to form a pressure-sensitive mat by injecting a mixture of PPG and TDI catalyst into a foam sponge to press-mold the upper and lower molds. There is no sitting end, and it pressurizes water vapor during press molding and neutralizes the toxic and removes bad smell by causing chemical reaction with the mixture. The effect is to get a mat.
