Bewitterungsstabiler Vliesstoff

Process for producing mineral fibre insulation boards and an apparatus for carrying out the process

The invention starts out from a process for producing mineral fibre insulation boards for heat and sound insulation of buildings, in particular boards under plaster or render, wherein the loose mineral fibres are provided with a binder and, if desired, with a hydrophobicising (waterproofing) agent and are collected to form a mineral wool sheet, and wherein the mineral wool sheet is brought to a desired thickness and is conveyed through a curing oven to cure the binder. To improve the process in such a way that it is possible to apply completely uniform layers, in particular plaster layers, which are equally thick everywhere, it is proposed that at least one of the large surfaces of the mineral wool sheet in the state in which the binder is not yet cured is provided with depressions, and that pressure-equalising bodies are introduced into the depressions in such a way that the outer surfaces of the bodies are essentially flush with the respective surface.

Manufacturing method of articles and sheets of thermotropic polymers

Fiber reinforced porous sheets

A method of preparing porous fiber reinforced polymer composite sheets has been developed to allow a more efficient pre-heating of the sheet prier to molding and includes the steps of blending reinforcing fibers with resin matrix forming fibers to form a web. This web is then heated to a temperature wherein the resin matrix forming fibers melt and envelope the reinforcing fibers, tacking them together at crossover points. The resultant web can then be directly heated very efficiently for molding. This web is highly porous allowing rapid heating at moderate pressure differentials during subsequent preheat steps. The microstruc-ture created when the resin matrix forming fibers are initially melted further enhances heating capability because the structure re-tains porosity during the subsequent heating step required for molding. Because the resin matrix forming fibers initially were un-iformly blended, a highly uniform distribution of polymeric material within the reinforcing fiber matrix yields molded parts with very uniform properties.

Manufacturing process of multi-component nonwoven fabric felt with lightness and high-strength

본 발명은 경량성과 강성이 우수한 복합부직포의 제조방법에 관한 것으로, 유리섬유 30 ~ 50중량%, 폴리프로필렌섬유 50 ~ 70중량%, 메타-아라미드섬유 0 ~ 10중량%로 구성된 니들펀칭 복합부직포를 제조하는 제1단계; 상기 니들펀칭 복합부직포를 온도가 190 ~ 240℃인 1차 가열금형에서 30 ~ 120초 동안 가열하는 제2단계; 상기 니들펀칭 복합부직포를 온도가 5 ~ 80℃인 1차 냉각금형에서 두께를 1 ~ 3㎜로 압착시켜 시트를 성형하는 제3단계; 상기 압착된 시트를 온도가 190 ~ 230℃인 2차 가열금형에서 45 ~ 120초 동안 재가열하는 제4단계; 상기 압착된 시트를 다시 온도가 80℃ 이하인 2차 냉각금형에서 30 ~ 120초 동안 냉간 성형하는 제5단계로 이루어지는 것을 특징으로 하고 있다. 또한, 상기 유리섬유는 굵기가 7 ~ 20㎛인 E-글라스 장섬유를 50 ~ 100mm의 길이로 절단한 것이고, 상기 폴리프로필렌섬유는 융점이 150 ~ 170℃, 클림프가 3 ~ 6개/cm, 굵기는 5 ~ 10데니어, 길이가 50 ~ 70mm인 것이며, 상기 메타-아라미드섬유는 굵기가 0.9 ~ 5.0dTex, 클림프는 3 ~ 6개/cm, 길이는 30 ~ 80mm임을 특징으로 한다. 그리고 상기 제1단계에서의 니들펀칭 복합부직포는 니들펀칭 전에 부직포 적층체를 형성하고, 그 상부에 폴리에스테르 장섬유 부직포를 위치시킨 후, 니들링하는 것을 특징으로 한다. 본 발명에 의한 경량성과 강성이 우수한 복합부직포의 제조방법은 1차 가열에 의해 용융된 복합부직포 내의 폴리프로필렌과 같은 열가소성 성분이 용융되었을 때 1차 냉각금형 공정 중에 용융된 성분이 압착된 시트의 표면으로 몰리게 되고, 2차 가열금형에서 재가열될 경우 고화된 폴리프로필렌 수지에 의해 결속되어진 유리섬유나 메타-아라미드섬유들이 원래의 부피특성을 회복하면서 가열 전의 원래 두께의 80% 이상으로 두께를 회복하게 되며, 또한 2차 냉각금형에서 최종제품으로 성형할 경우 용융된 폴리프로필렌 성분이 재고화되면서 원하는 제품형태로 성형되는데, 이런 과정을 거쳐 성형된 최종제품의 두께에 따른 폴리프로필렌의 함량분포는 1회 가열과 1회 냉각성형으로 제조된 제품과는 매우 상이한 함량분포를 나타내므로, 1차 가열과 냉각금형의 온도, 시간 등과 같은 조건에 의해 다소 차이는 있지만 금형과 맞닿는 표면에서의 폴리프로필렌의 함량이 내부에 비해 높게 분포됨으로써 이러한 양 표면층에서의 폴리프로필렌의 높은 함량이 최종제품의 강도를 올리는데 역할을 하는 것이다. 그리고 본 발명의 제조방법은 공정의 배열방법에 따라서는 1차 가열과 1차 냉각을 가열, 압착, 냉각이 가능한 연속상의 설비를 이용해 제조할 수 있으며, 이렇게 제조된 압착시트를 최종 성형공정으로 이동시켜 재단, 가열, 냉각압착을 통해 가볍고 강도가 우수하며 수분에도 안정한 자동차용 내장재를 제조하게 된다.
