본 출원인이 제출한 특허 출원번호 제10-1998-0011394로 (고안의 명칭 : 방음 적층체) 개량한 고안으로 흡음 성능이 우수한 발포체에 ㎠당 일정개수의 구멍을 형성시키고 구멍을 형성시킨 발포체 표면 위에 통기성이 있는 직포를 접착제 또는 열융착으로 합지한 후 상기 적층체 하부에 상기 적층체와 동일한 발포체 및 제진제를 접착제 또는 열융착으로 덧붙인다.The patent application No. 10-1998-0011394 filed by the present applicant (designation name: soundproof laminate) on the foam surface having a certain number of holes per cm2 formed in the foam having excellent sound absorption performance and formed on the surface of the foam After the breathable woven fabric is laminated with adhesive or heat fusion, the same foam and vibration damper as the laminate is added to the bottom of the laminate with adhesive or heat fusion.

직포는 각종 직물류, 천(cloth), 부직포, 벽지, P.E, P.P, 아크릴시이트 및 통기성이 있는 필름(FILM)으로 대체 가능하며 발포체는 열경화성 발포체 또는 열가소성 발포체이다.Woven fabrics can be replaced with various fabrics, cloths, nonwovens, wallpaper, P.E, P.P, acrylic sheets and breathable films (FILMs) and the foams are thermoset foams or thermoplastic foams.

이러한 본 고안 방음 적층체는 제품의 특성이 열경화성 발포체 및 열가소성 발포체에 난연 및 내항균처리를 하여 균에 의한 품질저하를 방지하여 발포체의 소음원을 그대로 유지하고 마감재료는 난연 및 항균처리를 한 색상과 무늬가 다양한 직포를 사용하였기 때문에 천장제, 벽체 기타 내장재로 사용할 수 있을 뿐 아니라, 열에 의한 성형으로 규격 제품을 생산할 수 있으며 보드 형태(TYPE)와 롤 형태(ROLL TYPE)의 생산이 가능하며 단 본에 5∼100㎜를 합지 않고 단 본에 생산할 수 있다.The soundproof laminate of the present invention has flame retardant and antibacterial treatment on the thermosetting foam and thermoplastic foam to prevent deterioration of bacteria by maintaining the noise source of the foam and the finishing material is flame retardant and antibacterial. Because it uses various woven fabrics, it can be used as ceiling materials, walls and other interior materials, and it can produce standard products by forming by heat, and it is possible to produce board type and roll type. It can be produced in the unit without adding 5 to 100 mm.

종전의 특허 출원한 방음 적층체의 경우에는 레자와 발포체를 합지하여 구멍을 형성한 후, 상기 적층체 하부에 발포체 또는 제진제를 덧붙인 적층체로 흡음 성능이 매우 우수하나, 표면에 구멍이 형성되어 내부 및 외부에 오랜 시간을 노출할 경우에 먼지 또는 오염물에 의하여 구멍이 막힐 가능성이 많으며 막혔을 경우 구멍에 의한 흡음 성능이 저하되고, 오염에 의한 외관이 매우 지저분하게 마감될 뿐 아니라, 뚫어져 있는 구멍이 시각적으로 매우 현란하게 비쳐질 수 있는 단점이 있다.In the case of the conventionally applied soundproof laminate, the lamination and the foam are laminated to form a hole, and then a foam or a vibration damper is added to the bottom of the laminate, and the sound absorption performance is very excellent. When exposed to the outside for a long time, the hole is likely to be clogged by dust or contaminants, and when blocked, the sound absorbing performance by the hole is degraded, and the appearance of the contamination is not very dirty, and the perforated hole is visually visible. There is a disadvantage that can be reflected very brilliantly.

본 고안의 특징은 발포체 표면에 뚫어져 있는 구멍 위에 통기성이 있는 마감재 직포를 덧붙여 주므로써 흡음 성능을 그대로 유지하면서 종전의 방음 적층체의 단점을 보완할 수 있게 된다.The feature of the present invention is that by adding a breathable finishing woven over the hole drilled on the foam surface it is possible to compensate for the shortcomings of the conventional sound insulation laminate while maintaining the sound absorbing performance.
