수반응 우레탄과 바닥용 경질 폴리우레탄을 이용한 바닥마감재의 성능향상에 관한 실험적 연구

A study on the improvement for performance of floor finishing materials using poly urethane with water reacting urethane

It is necessary for the new material and construction concept to make up for weak point which related to high durability and finish ability to solve exposure limit of exist construction method. This paper is deal with performance test(tier load, anti abrasion, anti impact, permeability, bond test) compositive using for water reacting soft urethane and rigid urethane to improve the exist problem which are crack movement, adhesive on the wet surface, impact and abrasion by tier load. It is getting decreasing demage compare with other exist materials after test by transfer load, movement and impact.
