Description
본 발명은 폴리우레탄레쟈가 접합된 폴리올레핀계 시트 또는 발포제품에 관한 것으로서, 상세히 설명하면 본 발명은 폴리올레핀계 sheet 또는 발포제품(P.P, P.E SHEET OR FOAM)와 폴리우레탄 레쟈층을 적층한 폴리우레탄레쟈가 접합된 폴리올레핀계 시트 또는 발포제품에 관한 것이다.The present invention relates to a polyolefin-based sheet or foamed product in which a polyurethane leather is bonded, and in detail, the present invention relates to a polyurethane leather in which a polyolefin-based sheet or foamed product (PP, PE sheet or foam) and a polyurethane leather layer are laminated. The present invention relates to a polyolefin-based sheet or a foamed product bonded thereto.
일반적으로 동질의 재질들은 열융착 또는 접착제 접착이 가능하나, 재질의 성분이 다른 재료들은 합지 할 경우 재질의 특성에 따라 재질의 표면층이 극성이되는 재질과 무극성이 되는 재질에 따라 타 재료를 합지하는 방법. 즉 열융착 방법 또는 접착제 접착 방법으로 나누어지나 특히 P.E 또는 P.P와 같은 올레핀계 sheet 또는 발포제품인 무극성 재질과 타 재질을 적층할 경우에는 열융착 방법 또는 접착제 방법으로 합지가 불가능하며 합지가 이루어진다 해도 이탈현상이 생긴다. NONPOLARITY (무극성) 재질을 합지를 할 경우 많은 다단계 공정을 거쳐야만 적층이 가능하나 적층후에 열로 인한 성형시 적층된 부분이 이탈되는 현상과 다단계로 적층되는 공정으로 비용(COST)이 증가되어 범용성으로 사용 선택함에 매우 어려움이 많았다.Generally, homogeneous materials can be heat-sealed or adhesively bonded, but materials with different materials may be laminated according to the characteristics of the material, depending on the characteristics of the material. Way. That is, it is divided into heat fusion method or adhesive method, but especially when laminating non-polar material and other materials, such as olefinic sheet or foam product such as PE or PP, it is impossible to be laminated by heat fusion method or adhesive method, and even if lamination occurs This occurs. In case of laminating non-porous material, it can be laminated only after many multi-step processes.However, after lamination, the laminated part is separated during the molding due to heat and the multi-step lamination process increases the cost (COST). Had a lot of difficulties.
종래의 기술은 단순한 바닥장식재 또는 내장재로 사용하는 올레핀계 sheet 또는 발포제품에 레쟈를 적층할 경우 외피는 직포에 레쟈가 합포된 레쟈(제품)를 구입한 후 올레핀계 sheet 또는 발포제품 표면에(프라이마)접착제를 1차 COATING후 건조시켜 표면을 접착제와 같은 성분으로 접착시키기 좋은 조건으로 상태를 만든 후 붙이고자 하는 레쟈 밑면에 같은 재질의 접착제를 코팅한 후 1차 접착 건조된 올레핀계sheet 또는 발포제품를 불꽃으로 멜팅(용융)시키면서 하부에 접착 처리된 피접착 재질과 합지한후 일정한 온도를 유지시키는 숙성실(건조기)에 저장 시킨후에 용도에 따라 사용된다. 올레핀계폼 sheet 또는 발포제품은 열성형성이 매우 높아 용도에 따라 성형되는 성형조건 (130℃~180℃)에 따라 적층된 부분이 이탈되는 문제점이 발생되어 고급스럽고 다양성을 요구하고 폼 SHEET와 레쟈층을 동시에 요구하는 가방, 배낭, 골프백등의 용도에는 사용치 못하고 레쟈 SHEET만 그대로 사용하는 경우가 많아 경량성과 성형성을 요구하는 용도에는 어려움이 많았던 것이다.The conventional technology is that when laminating the olefin sheet or foam product used as a simple floor decoration or interior material, the outer skin is purchased with the leather (product) in the woven fabric and then on the surface of the olefin sheet or foam product ( Forehead) The adhesive is dried after the first coating, and the surface is made to be in good condition to bond the surface with the same ingredients as the adhesive. After coating the adhesive of the same material on the bottom of the leather to be applied, the first adhesive dried olefin sheet or foam It is used depending on the purpose after laminating the product with the material to be glued to the bottom while melting (melting) it with a flame and storing it in a aging chamber (dryer) that maintains a constant temperature. Olefin foam sheet or foamed product has high thermoformability, so that the laminated part is separated according to the molding conditions (130 ℃ ~ 180 ℃) formed according to the use, so it requires high quality and diversity and forms foam sheet and leather layer. At the same time, it is difficult to use for a bag, a backpack, a golf bag, etc., but only a leather seat is used as it is.

본래 폴리올레핀계 sheet 또는 발포제품(P.P, P.E SHEET OR FOAM)는 자기와 동질한 재질의 경우에만 열융착 (HEATING LAMILATION)방법으로 적층이 가능하고 타재질를 합지할 경우 타재질에 P.P 또는 P.E SHEET OR FOAM에 접착제를 도포 건조하여 접착제와 같은 성분의 조건상태를 만든후에 접착하고자 하는 레쟈 뒷면에 접착제를 코팅한후 1차 접착 건조된 sheet 및 발포제품 표면을 열로 용융시키면서 접착시킬수 있으나 열성형조건 (130℃~180℃)에 따라 접합된 올레핀계 재질과 폴리우레탄 레쟈 분리로 접착성이 완전하지 못하고 잘 떨어진다.Polyolefin-based sheet or foamed product (PP, PE SHEET OR FOAM) can be laminated by heat sealing method only when the material is the same as porcelain. When laminating other materials, PP or PE sheet or foam After the adhesive is applied and dried to make the condition of the components such as the adhesive, the adhesive is coated on the back of the leather to be bonded, and then the first adhesive dried sheet and the surface of the foamed product can be bonded by melting with heat. ~ 180 ℃), the adhesiveness is not perfect and falls off due to the separation of the olefin-based material and the polyurethane leather.
또한 같은 재질끼리 열융착에 의한 접착성 또한 열성형 조건에 잘 분리되어 사용상에 어려움이 많았다.In addition, the adhesion between the same materials by heat fusion was also difficult to use because it is well separated by the thermoforming conditions.
