Description
본 발명은 폐섬유가 함유된 건축 구조물의 층간바닥 차음재를 제조하는 방법에 관한 것으로 보다 상세하게는 통상의 층간 바닥 차음재가 여러 종류 있으나 건축 구조물에서 물리적, 화학적 요건을 충족시킬 수 있는 바닥 차음재는 극히 드물다.The present invention relates to a method for manufacturing an interlayer floor sound insulation material of a building structure containing waste fibers. More specifically, there are many kinds of conventional floor insulation sound insulation materials, but the floor sound insulation material that can meet physical and chemical requirements in building structures is extremely rare.
종래로부터 건축 구조물 층간의 바닥 충격음을 차단하기 위하여 사용되는 차음재로는 유리섬유·일반섬유 쉬-트, 발포성 E.V.A(Ethylene Vinil Acetate)쉬-트, 고무 쉬-트, 발포 포리스치렌 쉬-트 등이 많이 이용되어 왔다.Conventionally, sound insulation materials used to block floor impact noise between floors of building structures include glass fiber, general fiber sheet, foamed EVA (Ethylene Vinil Acetate) sheet, rubber sheet, foamed porric styrene sheet, etc. It has been used a lot.
그러나 상기제품의 재질로 시공한 경우 건축 구조물상 물리적, 화학적 요구조건을 충족시키지 못하여 하자 발생이 빈번하였다.However, when the construction of the material of the product did not meet the physical and chemical requirements on the building structure frequently occurred defects.
즉, 책장이나 피아노, 냉장고 등의 장기간 하중으로 인하여 바닥크랙 또는 침하현상이 발생하며, 습기를 흡수하여 곰팡이가 생겨 차음성능이 저하되고 보일러 열에 장기간 노출됨으로서 재질의 변화와 수축현상이 생기기도 하였다.That is, floor cracking or sinking occurs due to long-term loads of bookshelves, pianos, refrigerators, etc., and moisture is absorbed to form molds, so that sound insulation is degraded.
이에 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 건축 구조물의 층간 바닥 충격음을 차단하면서도 물리적, 화학적 요건을 충적시키는 것을 목적으로 한다.Accordingly, an object of the present invention is to meet the physical and chemical requirements while blocking the floor floor impact sound of a building structure in order to solve the conventional problems as described above.
이와 같이 상기한 목적을 달성하기 위하여 본 발명은In order to achieve the above object the present invention
(1) H2 O 100Kg을 가열하여 60℃∼ 70℃ 에서 P.V.A(Poly Vinil Acetate) 20Kg을 용해시키고 여기에(1) 100 Kg of H 2 O is heated to dissolve 20 Kg of PVA (Poly Vinil Acetate) at 60 ° C to 70 ° C.
(2) CaCl2 (염화칼슘) 19Kg을 용해시켜 농도 11°Be'를 만들었다(2) 19 Kg of CaCl 2 (calcium chloride) was dissolved to give a concentration of 11 ° Be '.
(3) 상기혼합용액(P.V.A + CaCl2 )100Kg에 시멘트 60Kg으로 반죽을 하여 점도를 750cps ∼800cps로 조절하였다.(3) 100 Kg of the mixed solution (PVA + CaCl 2 ) was kneaded with 60 Kg of cement to adjust the viscosity to 750 cps to 800 cps.
(4) (3)의 시멘트 반죽에 페섬유 6Kg ∼ 7Kg을 혼합하여 교반기에서 30분간 재반죽하여(4) 6Kg to 7Kg of waste fiber is mixed with cement paste of (3) and kneaded again in a stirrer for 30 minutes
(5) 가로 50㎝, 세로50㎝, 두께2㎝의 형틀에 계속 충진시켜(5) Fill the mold 50cm long, 50cm long and 2cm thick
(6) 72시간 양생 후 형틀을 해체함으로서 층간 바닥 차음재를 만들었다.(6) After 72 hours of curing, the interlayer floor sound insulation was made by dismantling the mold.
상기공정에서 P.V.A를 첨가 용해한 것은 외부 충격에 크랙으로 인한 파손을 방지하기 위한 것이며, H2 O를 60℃∼ 70℃로 가열하는 것은 50℃ 이하의 온도에서는 P.V.A가 잘 용해되지 않음이며, H2 O 100Kg에 P.V.A 20Kg 비율로 용해한 것은 30Kg을 첨가 용해할 경우 강도가 많이 저하되므로 20Kg비율이 바람직하였다.PVA is added and dissolved in the above process to prevent damage due to cracks in external impact, and heating of H 2 O to 60 ° C. to 70 ° C. does not readily dissolve PVA at a temperature of 50 ° C. or lower, and H 2 The 20 Kg ratio was preferable because 30 Kg was dissolved in 100 Kg of O at a rate of 20 Kg.
(2)의 CaCl2 (염화칼슘)를 첨가 용해하는 것은 강도를 높이면서도 양생을 촉진시키기 위함이며 농도를 11°Be'로 정함은 10°Be'미만일 경우 응결 속도가 느리면서 강도가 낮으며 12°Be'이상인 경우는 급결 현상이 발생되므로 작업이 어려워짐으로 농도는 11°Be'가 적절하였다.The dissolution of CaCl 2 (calcium chloride) in (2) is to promote curing while increasing the strength, and the concentration is set to 11 ° Be '. If the concentration is less than 10 ° Be', the condensation rate is low and the strength is low. If Be 'is more than 11 ° Be' was suitable because of the difficulty in working because of the phenomenon of fastening.
또한 (3)의 혼합용액에 시멘트를 첨가 반죽하여 점도를 750cps ∼800cps로 조절하는 것은 750cps미만이 될 경우 시멘트 함량이 적어 강도가 저하되며 800cps이상이 될 경우 시멘트 함량이 너무 많아 폐섬유 혼합 교반 작업이 불가능 하였다.In addition, to adjust the viscosity by adding cement to the mixed solution of (3) to adjust the viscosity to 750cps ~ 800cps, when the cement content is less than 750cps, the cement content is low and the strength decreases. This was impossible.
그리고 (3)의 시멘트 반죽에 폐섬유를 혼합 재반죽 하는 것은 차음 성능을 높이기 위한 것으로 폐섬유 7Kg이상을 혼합한 결과 섬유량이 많아 교반작업이 어려웠으며 6Kg미만을 혼합하였을 때는 교반작업은 잘되나 차음성능이 저하되므로 6Kg ∼ 7Kg이 바람직하였다.And mixing and re-mixing the waste fiber in the cement dough of (3) is to improve the sound insulation performance. As a result of mixing more than 7Kg of waste fiber, it is difficult to stir due to the large amount of fiber. Since the performance falls, 6 Kg-7 Kg were preferable.

(4) 결과 고찰(4) Review of results
혼합 용액(P.V.A + CaCl2 )과 시멘트의 배합 비율에서 Blend 물성 시험결과 시멘트 함량 증가에 따라 강도가 높아짐을 알 수 있다.As a result of the blend property test in the mixing ratio of the mixed solution (PVA + CaCl 2 ) and cement, the strength increases with increasing cement content.
혼합용액 중 P.V.A함량이 증가 할수록 강도는 하락되며 CaCl2 농도가 높아질 수록 강도도 높아짐으로 함량 비율 조정이 필요하였다.As the PVA content in the mixed solution increased, the strength decreased, and as the CaCl 2 concentration increased, the strength increased.
또한 강도가 높아짐에 따라 흡수율, 잔류변형율, 내구성, 충격음 성능 등 항목별 실험 내용이 좋아짐을 알 수 있었다.In addition, as the strength increases, the experimental contents of each item such as absorption rate, residual strain rate, durability, and impact sound performance are improved.
