Abstract
Description
本発明は住宅の床面に用いられる床用化粧材に関する。特には人やペットが生活する室内の床面に用いる床用化粧材に関する。 The present invention relates to a floor decorative material used for a floor surface of a house. In particular, the present invention relates to a flooring cosmetic material used on a floor surface in a room where people and pets live.
主に木質系基材と化粧シートからなる床用化粧材は、近年の住宅の流行となってきている。しかし、犬などのペットを室内で飼育する上で、滑り易いためにペットの足や股関節に負担がかかり骨折などの原因ともなりかねないという問題があった。 Floor decorative materials mainly composed of a wood-based base material and a decorative sheet have become a popular trend in housing in recent years. However, when pets such as dogs are raised indoors, there is a problem that they are slippery and may cause a burden on the pet's legs and hip joints and cause fractures.
そこでペットの爪が引っかかるように、化粧シートの表面保護層に用いる硬化型樹脂に球状粒子を含有させ、これを塗工、硬化することで、表面にある程度の凹凸を設けるという方法が考えられた。しかし、あまり球状粒子が多かったり粒径が大きかったりすると表面保護層からはみ出て、布で表面を擦ったり、シート同士を摺り合わせたりした際に粒子が剥がれて白粉が出るという問題が発生した。 Therefore, a method has been considered in which spherical particles are contained in the curable resin used for the surface protective layer of the decorative sheet so that the pet's nail is caught, and a certain degree of irregularities is provided on the surface by coating and curing the spherical particles. . However, if there are too many spherical particles or the particle size is too large, the particles may protrude from the surface protective layer, and when the surface is rubbed with a cloth or the sheets are rubbed together, a problem arises in that the particles are peeled off and white powder is produced.
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、その課題とするところは、人やペットが滑ったり転んだりすることがなく、かつ表面の耐摺動性を有して白粉の発生がない床用化粧材を提供することにある。 The present invention has been made in order to solve such problems, and the problem is that a person or pet does not slip or roll and has a sliding resistance on the surface. An object of the present invention is to provide a floor decorative material that does not generate white powder.
本発明はこの課題を解決したものであり即ちその請求項１記載の発明は、木質系基材上に着色熱可塑性樹脂層、絵柄模様層、透明熱可塑性樹脂層、表面保護層を少なくともこの順に有してなる床用化粧材において、前記表面保護層に粒径６〜８μｍの球形ポリエチレンワックスを１〜３重量％含有させたことを特徴とする床用化粧材である。 The present invention solves this problem, that is, the invention according to claim 1 includes a colored thermoplastic resin layer, a pattern layer, a transparent thermoplastic resin layer, and a surface protective layer in this order on a wooden base material. The floor decorative material according to claim 1, wherein the surface protective layer contains 1 to 3% by weight of spherical polyethylene wax having a particle diameter of 6 to 8 μm.
本発明ではその表面保護層に含有する球状粒子を球形ポリエチレンワックスとし、かつその粒径と含有量を限定することで、人やペットが滑ったり転んだりすることのない摩擦を有するものとすると同時に耐擦動性を有するものとすることを可能とした。 In the present invention, spherical particles contained in the surface protective layer are made of spherical polyethylene wax, and by limiting the particle size and content thereof, it is possible to have friction that prevents a person or pet from slipping or rolling. It was possible to have friction resistance.
