본 발명은 건축용 적층재 및 그 조성물에 관한 것으로서, 특히 여러가지 방음, 차음, 제진, 방진 및 단열특성이 우수기능성재질을 복합구성시켜준 고무계 발포체 조성물과 그것을 이용한 적층재에 관한 것이다.The present invention relates to a building laminate and a composition thereof, and more particularly to a rubber-based foam composition and a laminate using the same in which various soundproofing, soundproofing, vibration damping, dustproof, and heat-insulating properties composite excellent functional materials.

아파트등의 고층건물의 바닥은 도면 제1과 같이 콘크리트슬라브(6)위에 장판 혹은 타일(1), 몰탈(2), 배관(3), 경량기포콘크리트(4), 및 제진층(5)을 차례로 적층 구성하고 있으나 제진층(5)에 해당되는 부분이 중요시되지 않아 기존의 건물에선 층간의 소음 및 각종 충격음이 상하층에 전달되어 소음공해와 사생활의 침해등의 문제가 지적되고 있다.The floor of a high-rise building such as an apartment is placed on a concrete slab (6), a floor plate or tile (1), mortar (2), piping (3), lightweight foam concrete (4), and the vibration damping layer (5) as shown in the first drawing. In order to be laminated in turn, but the part corresponding to the vibration damping layer (5) is not important, the noise between the floors and various impact sounds are transmitted to the upper and lower floors in the existing building has been pointed out problems such as noise pollution and privacy invasion.

이와같은 각종 소음과 충격음을 방지하기 위하여 제진층(5)의 도입을 추구하여 우레탄스폰지, 스티로폴등의 단순한 발포체나 고무를 기초로한 제진판 혹은 글라스울등을 깔아왔으며, 최근에는 콜크입자 혹은 폐고무 입자를 단순한 수지계 바인더로 쉬트화하여 제진층으로 사용하거나 개질아스팔트 조성물을 제진재로 사용하고 있다. 그러나 종래의 이들 발포체나 제진판들은 단순한 구조물로 되어 있어 각각이 나름대로 기능을 수행하지만, 쾌적한 주거 및 사무환경에 필요한 차음, 방음, 제진 및 방진등의 복합적인 기능을 충분히 발휘하지 못하여, 건물완성 후 바닥을 통하여 층간의 소음이 그대로 전달되는 문제점이 있었다. 또한 아스팔트를 사용한 경우에는 내열성이 좋지 않아 온도상승시 흘러내리거나 온도변화, 진동등에 의한 콘크리트 조성물의 균열발생시 쉽게 크랙이 발생하는 단점이 있다.In order to prevent such various kinds of noises and impact sounds, a simple foam such as urethane sponge and styropol or a vibration damping plate or glass wool based on rubber have been laid. Recently, cork particles or waste Rubber particles are sheeted with a simple resin binder to be used as a vibration damping layer or a modified asphalt composition is used as a vibration damping material. However, these conventional foams and damping plates have a simple structure, each of which performs its own function, but does not sufficiently perform the complex functions such as sound insulation, soundproofing, dustproofing, and dustproofing necessary for a comfortable residential and office environment. There was a problem that the noise between floors was transmitted through the floor. In addition, when asphalt is used, there is a disadvantage in that heat resistance is not good and cracks easily occur when a concrete composition is cracked due to flow down or temperature change or vibration.

Saab, process oils and plasticizers also impart shock absorbing and damping properties.

본 발명에서 사용한 콜크입자는 입자크기가 0.5mm∼20mm정도인 칩상의 콜크를 사용할 수 있으며, 폐고무 입자는 입자크기가 0.1mm∼20mm정도인 칩상 혹은 침상의 폐고무 입자로, 폐타이어입자도 사용할 수 있다. 콜크입자와 폐고무 입자는 고무 100중량부에 대하여 10∼400중량부, 좋게는 50∼300중량부 사용이 가능하다. 조성성분이 10중량부일 이하일 경우에는 기능성 발포체에서 원하는 흡음, 제진 및 단열성을 나타낼 수 없으며, 400중량부 이상에서는 고무혼련 작업시 작업성이 나빠지며, 안정한 발포체를 제조하기가 곤란하고 탄성이 저하된다.As the cork particles used in the present invention, chipped cork having a particle size of about 0.5 mm to 20 mm may be used, and waste rubber particles are chipped or needle shaped waste rubber particles having a particle size of about 0.1 mm to 20 mm, and used tire particles may also be used. Can be used. The cork particles and the waste rubber particles may be used in an amount of 10 to 400 parts by weight, preferably 50 to 300 parts by weight, based on 100 parts by weight of rubber. If the composition is less than 10 parts by weight, the functional foam may not exhibit the desired sound absorption, vibration damping, and heat insulation properties. At 400 parts by weight or more, workability becomes poor during rubber kneading, and it is difficult to produce a stable foam and elasticity is lowered. .

제진성 충전제로는 황산바륨, 황산칼슘, 마이카, 탈크, 클레이, 흑연, 탄산마그네슘, 탄산칼슘, 카아본블랙, 실리카, 각종 위스커 및 각종 금속분말가루분을 고무 100중량부에 대하여 3∼150중량부 사용할 수 있으며, 좋게는 5∼100중량부 사용할 수 있다. 조성성분이 3중량부 이하일 경우에는 다기능성 발포체에 제진특성을 크게 부여할 수 없으며, 150 중량부 이상에서는 다기능성 발포체의 경도가 높아지고 발포체의 제조가 원활하게 되지 못한다.Vibrating fillers include 3 to 150 parts by weight of barium sulfate, calcium sulfate, mica, talc, clay, graphite, magnesium carbonate, calcium carbonate, carbon black, silica, various whiskers and various metal powder powders based on 100 parts by weight of rubber. It can be used, Preferably 5-100 weight part can be used. When the composition component is 3 parts by weight or less, it is not possible to impart large vibration damping properties to the multifunctional foam. When the composition is 150 parts by weight or more, the hardness of the multifunctional foam is increased and the production of the foam is not smooth.

제진성을 부여하는 기능을 갖는 아스팔트로는 스트레이트 아스팔트, 부라운 아스팔트, 개질 아스팔트등을 고무 100중량부에 대하여 0.05∼100중량부 사용할 수 있으며, 좋게는 2∼80중량부 사용할 수 있다. 아스팔트를 0.05중량부 이하로 사용할 경우에는 아스팔트 첨가에 의한 제진특성 향상을 기대할 수 없으며, 100중량부 이상에서는 고무배합물의 가공작업시 작업성이 나빠지며, 발포체의 안정성이 나빠진다.As asphalt having a function of imparting vibration damping properties, straight asphalt, brown asphalt, modified asphalt and the like may be used in an amount of 0.05 to 100 parts by weight, and preferably 2 to 80 parts by weight. When asphalt is used in an amount of 0.05 parts by weight or less, it is not expected to improve the damping characteristics by adding asphalt, and in the case of 100 parts by weight or more, workability worsens during processing of the rubber compound and the stability of the foam becomes poor.

이들 기능성 조성물들이 혼합된 고무계 혼합물을 가교시키기 위해서 가교제로는 고무가황에 일반적으로 사용되는 황, 불용성 황 및 유기과산화물 가교제를 사용할 수 있다. 가교제는 고무 100중량부에 대하여 0.05∼5중량부, 좋게는 0.2∼4중량부 사용이 가능하다. 가교제 성분이 0.05중량부 이하에서는 원활한 가교가 진행되지 못하여 발포제가 불안정하고 발포체의 탄성이 떨어지며, 5중량부 이상에서는 발포체가 높은 가교율로 인해 경도가 높고 취화하는 현상을 나타낸다.In order to crosslink the rubber-based mixture in which these functional compositions are mixed, as the crosslinking agent, sulfur, insoluble sulfur and organic peroxide crosslinking agents generally used in rubber vulcanization may be used. The crosslinking agent may be used in an amount of 0.05 to 5 parts by weight, preferably 0.2 to 4 parts by weight, based on 100 parts by weight of rubber. When the crosslinking agent component is 0.05 parts by weight or less, smooth crosslinking does not proceed, the foaming agent is unstable, and the elasticity of the foam is inferior. At 5 parts by weight or more, the foam exhibits high hardness and embrittlement due to the high crosslinking rate.

The mixture of lightweight foamed concrete to be placed on the laminate can prevent the leakage of impact sound by preventing it from leaking under the laminate and coming into direct contact with the concrete layer at the bottom. And the function of vibration suppression is further improved.

이때 필림층은 기존의 PE, PP EVA등의 각종 수지필림을 사용할 수 있으며, 종이패드로는 목편이나 펄프를 주로하여 제조된 종이 석유아스팔트를 함침시켜 얻은 아스팔트함침 종이패드를 사용할 수 있다.In this case, the film layer may use various resin films such as PE and PP EVA, and as the paper pad, an asphalt-impregnated paper pad obtained by impregnating paper petroleum asphalt, which is mainly made of wood or pulp, may be used.
