In connection with prior art document 1 (registration patent 10-2013108 manufacturing process of a cutting-type foam mat, and a cutting-type foam mat produced thereby), an attachment method using an adhesive is disclosed.

하지만 선행문헌 1은 수성PU, 아크릴, 에폭시 등을 이용한 접착제로 장기간 사용 시 유해물질이 발생될 수 있으며, 접착층을 통한 접착이 이루어져 각기 다른 소재가 접착될 때 일체감이 부족하고, 접착력이 약해짐에 따라 내구성이 저하되는 문제가 발생하게 된다.However, prior art document 1 is an adhesive using water-based PU, acrylic, epoxy, etc., and may cause harmful substances when used for a long time.Adhesion through the adhesive layer is made, and when different materials are adhered, the sense of unity is insufficient and the adhesion is weak. Accordingly, a problem occurs in that durability is deteriorated.
