Description

  The present invention relates to a decorative sheet for floors having a protective film.

  As a floor decorative sheet, for example, Patent Documents 1 and 2 disclose a laminate in which a decorative sheet is laminated on a thick synthetic resin layer (so-called backer layer) made of polyolefin resin. These decorative sheets for flooring are made into flooring decorative materials by sticking the backer layer side to various adherends. The backer layer is a thick synthetic resin layer (reinforcing layer) provided for imparting hardness, strength and the like to the decorative sheet for flooring.

Since the decorative sheet for flooring may be scratched or cut on the surface during transportation or processing such as cutting, a device capable of preventing this is required. There is also a need for a device that can prevent a paint or the like from adhering to a portion other than the painted portion when partially painting the surface. In addition, in floor decorative sheets having a concavo-convex pattern on the front surface, the concavo-convex pattern may become overheated (disappearance or reduction of the concavo-convex pattern) when forming a backer layer on the back surface by melt extrusion of resin There is also a need for a device that can effectively prevent this. The uneven pattern provided by embossing is also referred to as “texture”, and the disappearance or reduction of the uneven pattern is also referred to as “texture return”.

«Uneven pattern»
The floor decorative sheet of the present invention has a concavo-convex pattern formed from the transparent surface protective layer side. This uneven pattern is shaped by, for example, embossing.

  Embossing is performed to give a desired texture such as a wood grain pattern to the decorative sheet. For example, after heating and softening the transparent surface protective layer on a heating drum, it is further heated to 140 to 170 ° C. with an infrared radiation heater, pressed and shaped with an embossed plate having a desired shape of uneven pattern, and cooled. A texture is given by fixing. Embossing can be performed with a known single wafer or rotary embossing machine.

  In the case of using the polyolefin resin and / or polyester resin, it is preferable to form and laminate a protective film by melt extrusion of these resins. For example, extrusion film formation can be performed by using a T-die extruder. Thus, when laminating a protective film by melt extrusion, since the molten resin flows along the shape of the concavo-convex pattern formed from the transparent surface protective layer side, it becomes a protective film. When the synthetic resin layer (backer layer) is formed by melt extrusion of the resin, disappearance or reduction of the uneven pattern due to heat is prevented.

  In addition to the above, the protective film includes vinyl chloride resin, urethane resin, acrylic resin, polyester resin, silicone resin, etc. as a base material, vinyl chloride resin, urethane resin, acrylic resin, polyester resin. A tack material having a resin, a silicone resin, or the like as an adhesive can also be used. Among these, acrylic resins are preferable. The tack material is preferably a substrate in which the above-mentioned pressure-sensitive adhesive is applied by coating, and the thickness of the pressure-sensitive adhesive is preferably about 5 to 50 μm, more preferably about 10 to 20 μm.

  When laminating a protective film on the transparent surface protective layer, the front surface of the transparent surface protective layer is preferably surface-treated. For example, it is preferable to perform known easy adhesion treatment such as ozone treatment, corona discharge treatment, plasma treatment, and degreasing treatment.

  By laminating the protective film, it is possible to prevent scratches and the like from adhering to the surface during transportation and processing. In particular, when a polyolefin-based resin or a polyester-based resin is used, it is difficult to impair the design properties because fuzz during cutting is effectively suppressed.

≪Synthetic resin layer≫
The floor decorative sheet of the present invention may be provided with a synthetic resin layer (so-called backer layer) having a thickness of 100 μm or more on the back surface of the base sheet.

  The backer layer is preferably composed of a thermoplastic resin, and is preferably a polypropylene resin. The polypropylene resin may be not only a homopolymer mainly composed of polypropylene but also a copolymer. Examples thereof include homopolypropylene resins, random polypropylene resins, block polypropylene resins, and α-olefins having a polypropylene crystal part and having 2 to 20 carbon atoms other than propylene. In addition, a propylene-α-olefin copolymer containing 15 mol% or more of a comonomer of ethylene, butene-1, 4-methylpentene-1, hexene-1, or octene-1 is also included.

  The backer layer may be a laminate of two or more layers. For example, a laminate of two or more polypropylene resin layers may be used.

  The thickness of the backer layer should just be 100 micrometers or more, and about 250-400 micrometers is preferable.

  The backer layer can be easily formed by, for example, extrusion of molten resin. When the coextrusion method is used, a backer layer made of a laminate can be easily formed. For coextrusion film formation, for example, a multi-manifold type or feed block type T-die can be used.

  After joining with the woody material, for example, according to the characteristics of the final product, cutting, use of a tenor, sane processing, provision of V-shaped grooves, chamfering on four sides, and the like may be performed.

  In the decorative sheet for floor according to the present invention, since the protective film is laminated on the front surface of the transparent surface protective layer, the floor decorative sheet is prevented from being damaged during transportation or processing. In addition, when a part of the surface is painted, a protective film is laminated on a portion other than the portion to be painted, thereby preventing a paint or the like from adhering to the portion other than the painted portion. In addition, since the protective film is laminated | stacked so that peeling is possible, after constructing | decorating a flooring decorative material, a protective film can be peeled easily and can use for actual use.
