Description

폴리우레탄 발포층이 형성된 합성수지 바닥장식재Synthetic resin flooring with polyurethane foam layer

그런데, 종래 PVC를 주원료하여 발포된 PVC발포층이 형성된 함성수지 바닥장식재에서, 그 발표량은 원재의 4배정도로서 발포효과가 뛰어나지 못하므로 단순히 완성층만을 갖는 목적으로 형성되었다. 따라서, 흡음효과를 가지도록 하기 위해서는 발포층을 두껍게 형성시켜야 하므로 많은 양의 PVC원재가 필요하게 되어 재료비가 상승한다는 문제점이 있었다.However, in the case of a shrinkable resin flooring having a PVC foaming layer formed by foaming the main raw material of PVC, the foaming effect is not excellent because the foaming effect is about four times as much as the raw material. Therefore, in order to have a sound absorbing effect, it is necessary to form a thick foam layer, so that a large amount of PVC raw material is required, which causes a problem that the material cost increases.

또한, 종래 PVC발포층이 형성된 바닥장식재의 PVC발포층에는 진균, 곰팡이 등이 쉽게 번식한다는 문제점이 있었다.In addition, there has been a problem that fungal, mold and the like easily reproduce on the PVC foam layer of the flooring material in which the PVC foam layer is formed.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 적은 량의 원재에 의해서도 흡음효과를 내기에 충분한 발포층을 형성함과 동시에 향균성을 갖는 폴리우레탄 발포층이 형성된 합성수지 바닥장식재를 제공하는데 있다.SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a synthetic resin floor having a polyurethane foam layer having an antibacterial property while forming a foam layer sufficient for a sound absorption effect even with a small amount of raw material, To provide a decorative material.
