Description
本発明は、屋内や屋外の建造物床面に敷設して用いる床材に関するものであって、特には耐衝撃性を有しかつ歩行感が良好なクッション性を有する床材に関する。 The present invention relates to a flooring material that is used by being laid on an indoor or outdoor building floor surface, and particularly relates to a flooring material that has impact resistance and cushioning properties with good walking feeling.
近年の屋内や屋外の建造物床面にはフローリング材が多く用いられている。フローリング材には、突板に塗装したものや、木質系樹脂シートに化粧シートをラミネートしたものなどが知られている。 In recent years, flooring materials are often used for indoor and outdoor building floors. Known flooring materials include those coated on a veneer and those obtained by laminating a decorative sheet on a wood-based resin sheet.
これらフローリング材には耐傷付き性が求められるため、ある程度の硬度が求められる。しかしその一方で衝撃吸収性も要求されるため、柔軟性も要求される。 Since these flooring materials are required to have scratch resistance, a certain degree of hardness is required. However, on the other hand, since shock absorption is also required, flexibility is also required.
最表面に耐傷性を有する化粧シートを設け、表面側に軟質層、床面側に硬質層を設ける方法も考えられたが、十分な衝撃吸収性を得ることが出来ない。軟質層の厚みや柔軟性を調整することで或る程度の衝撃吸収性を得ることができたとしても、その場合は歩行感が悪くなったり、化粧シートとの層間が弱くなったり、耐傷性が弱くなったりするという問題点があった。 A method of providing a decorative sheet having scratch resistance on the outermost surface, and providing a soft layer on the surface side and a hard layer on the floor side has been considered, but sufficient impact absorbability cannot be obtained. Even if it is possible to obtain a certain level of shock absorption by adjusting the thickness and flexibility of the soft layer, in that case, the feeling of walking becomes worse, the interlayer between the decorative sheet becomes weak, and scratch resistance There was a problem that became weak.
そのため、表面側に硬質層、床面側に軟質層を有するフローリング材が効果的であると考えられた。しかしながら硬質層の下に軟質層を設けただけでは、十分な衝撃吸収性を発現できない。軟質層の効果が大きいとフワフワしすぎるものとなり、硬質層の効果が大きいと軟質層による衝撃吸収性が発現できない。これには用いる構成材料や発泡などの加工方法だけでなく、層厚なども影響するが、一番の問題は硬質層と軟質層のバランスにあるため、その条件設定が困難であった。 Therefore, it was considered that a flooring material having a hard layer on the front side and a soft layer on the floor side is effective. However, sufficient shock absorption cannot be achieved simply by providing a soft layer under the hard layer. If the effect of the soft layer is great, the soft layer becomes too fluffy. If the effect of the hard layer is great, the impact absorption by the soft layer cannot be expressed. This affects not only the constituent materials used and processing methods such as foaming, but also the layer thickness, etc., but the main problem is the balance between the hard layer and the soft layer, and it was difficult to set the conditions.
本発明はこのような問題点を解決するためになされたものであり、すなわちその課題とするところは、しっかりした歩行感と表面の耐傷性を有しつつ、十分な衝撃吸収性を有する床材を提供することにある。 The present invention has been made in order to solve such problems.
