Description

  The present invention relates to a polyvinyl chloride antiskid floor material, and more particularly, to a vinyl chloride antiskid floor material integrated with a polyester base fabric having a concavo-convex pattern formed on the surface by a coating of polyvinyl chloride.

  Polyvinyl chloride flooring (hereinafter referred to as “polyvinyl chloride” or simply “vinyl chloride”) is roughly divided into tiles and sheets. PVC tiles are approximately 30cm square and 45cm square squares, and are used to protect and decorate the floor by sticking like tiles. PVC sheet is generally a long product with a width of 1.82m and is spread over the entire floor. To use. A fashionable flooring was born, such as a cushion floor with a gravure-printed PVC layer on top of a foamed PVC layer.

  Recently, polyolefin-based products have been developed as synthetic resin-based flooring materials. Good workability, strength and scratch resistance, excellent design and design, and vivid coloring. It has the characteristics of being hard to burn, cheap in price, and compatible with water-based adhesives that are good for the environment, and is also an advantage of PVC flooring because it contributes greatly to the recycling of agricultural bean.

  When classifying conventional typical PVC flooring materials from the constituent materials, the woven fabric such as natural fiber and synthetic fiber is used as the backing material, and the vinyl chloride intermediate layer containing a large amount of filler and the relatively pure vinyl chloride surface layer Inlaid sheet, woven fabric, non-woven fabric, vinyl chloride laminated with a non-woven foam layer with no foamed layer, non-woven fabric such as paper, felt, glass fiber or vinyl layer and vinyl chloride chips laminated with vinyl chloride A soft inlaid sheet in which colored vinyl chloride chips are laminated on a backing material such as a vinyl chloride intermediate layer and a transparent vinyl chloride surface layer is provided, and a foamed vinyl chloride layer or colored vinyl chips on a backing material A composite PVC sheet with a foam layer with a surface layer provided by laminating or a foamed vinyl chloride layer with a pattern printed on the backing material as an intermediate layer It is divided into flooring sheets with provided a transparent vinyl chloride surface foam layer.

  In addition to wear resistance, dimensional stability, decorativeness, light weight, cushioning, soft walking feeling, sound absorption, scratch resistance, etc., the basic performance of such flooring is anti-slip, that is, slips when walking The property of preventing this is extremely important.

  Conventionally, as a method for imparting anti-slip properties to a flooring material, it has been a mainstream to apply a concavo-convex pattern on the surface of the flooring material such as a cushion floor by a method such as embossing. In this case, the embossing is performed while heating using a molding roller called an embossing roll.

  Embossing rolls are made of iron core rolls or copper plated rolls with the desired engraving using various shapes of mills and tools, and further plated with chrome or nickel chrome for durability. It is manufactured by the procedure of improving and is expensive.

  Embossed rolls are required for extremely complex patterns, geometric patterns, or patterns such as lattices, turtle shells, etc., but simple embossing such as lines, streaks, points, or a combination of these, or manufacturing Depending on the lot, it can be expensive to produce embossing rolls.

  Furthermore, when using an embossing roll, at least two rolls of an embossing roll and a pressure roll (backup roll) are required. Accordingly, when embossing is performed on the surface of a sheet made of resin flooring, wall material, ceiling material, outer wall material or the like, the entire apparatus becomes large. In this case, in the case of a very complicated pattern, geometric pattern, or a packed pattern such as a lattice, turtle shell, etc., or in mass production, the cost can be absorbed, but in the case of simple embossing or small lot May be expensive.

  There are innumerable patent documents disclosing methods using an embossing roll. For example, Patent Document 1 discloses a “molding method of a vinyl resin sheet material having an embossed pattern surface”. This conventional method discloses a method of forming a long protrusion on a carpet pile by an embossing method using a sintered layer.

  Patent Document 2 discloses a method for producing an embossed decorative sheet that extrudes a transparent thermoplastic resin and immediately press-bonds it to an embossing roll and has good reproducibility of the embossed shape.

  Furthermore, there is a method of using inlaid chip pellets that do not use an embossing roll as a special patterning method.

  For example, Patent Document 3 outlines that a linoleum composition particle having a relatively low ripening degree is placed on a backing material by a stencil method to form a tessera pattern, and a joint is filled with the stencil method by aging linoleum composition particles. Pressed with a press plate, compressed to 1/3 of the initial thickness, and after a predetermined time, when removed from the press, the compressed composition expanded slightly and the joints expanded significantly more than the tessellar pattern A method of forming a mosaic pattern is disclosed.

  Similarly, Patent Documents 3, 4, 5 and the like disclose a method of manufacturing a flooring material using inlaid chip pellets that do not use an embossing roll.

However, the method of manufacturing flooring using inlaid chip pellets is a method that does not use an embossing roll, but the pattern that is formed is very decorative and is simply intended for non-slip. It is not what I did.

  The problem to be solved by the present invention is to provide a method for producing a polyvinyl chloride antiskid floor material and a polyvinyl chloride antiskid floor material without using an expensive embossing roll.

  Yet another problem to be solved by the present invention is to coat a polyester base fabric with a concavo-convex pattern with a polyvinyl chloride resin without using an embossing roll, and use it as a surface layer to form a substrate having a predetermined structure. And providing a flooring material and a flooring material.

  Conventionally, when embossing is performed on a resin sheet using an embossing roll, an embossing roll engraved with a predetermined pattern is pressed against the surface of the resin sheet, heated and molded, and fixed with resin. In other words, it is like forming a concavo-convex pattern on the base resin sheet by pressing the ironing iron. The base resin having the same melting point and the resin forming the embossing An uneven pattern is formed on the surface.

  Therefore, the present inventor previously coated a concavo-convex pattern with a polyvinyl chloride resin on the surface of the polyester base fabric, and integrated the polyvinyl chloride resin layer, the polyvinyl chloride resin intermediate layer, and the base fabric in this order. By making it into a flooring, the object is to achieve an anti-slip effect by the concavo-convex pattern of the polyvinyl chloride resin formed on the surface of the polyester base fabric.

  Accordingly, the flooring of the present invention comprises (1) a concavo-convex pattern layer of polyvinyl chloride resin, (2) polyester fiber woven fabric, (3) polyvinyl chloride resin layer, (4) polyvinyl chloride resin intermediate layer and (5 ) A five-layer structure of the base fabric.

  The uneven pattern layer of the polyvinyl chloride resin of the flooring of the present invention will be described. As for the structure of the concavo-convex portion, the height of the convex portion can be arbitrarily set within a range of 0.1 to 0.4 mm as measured from the surface on which the concavo-convex portion is formed. Therefore, the depth of the recess is also in the range of 0.1 to 0.4 mm. When the height of the convex portion is 0.1 mm or less, the anti-slip effect is low, which is not preferable. On the other hand, when the height is 0.4 mm or more, the anti-slip effect is excessively increased, such as infants, elderly people, sick people, physically weak people, etc. This is not preferable because it hinders walking or running of a carriage.

  The flooring of the present invention uses various materials that have been conventionally used as a backing material for a flooring as a base fabric, and the surface of the flooring is coated with a concavo-convex pattern of polyvinyl chloride resin.

  Therefore, this base fabric is effective not only as a support material for coating the concavo-convex pattern of the polyvinyl chloride resin, but also in the dimensional stability of the entire flooring material and the effect of preventing delamination.

  The base fabric used in the present invention can be arbitrarily selected from those conventionally used, such as woven fabrics such as natural fibers and synthetic fibers, and nonwoven fabrics such as paper, felt and glass fibers. However, from the viewpoint of various physical properties such as dimensional stability, plain weaving of polyester fibers, that is, cold koji is most preferable.

As the plain weave of the polyester fiber, that is, the cold weather, for example, the following specifications are preferable.

  The intermediate layer of the flooring of the present invention is a main component of the flooring of the present invention and is a solid layer of polyvinyl chloride. This thickness is preferably in the range of 2.0 to 2.5 mm. This layer is manufactured using not only unused (virgin) PVC, but also 100% agricultural vinyl or a mixture of agricultural and unused (virgin) PVC. If agricultural bean is used, it can greatly contribute to the recycling of agricultural bean, ie used vinyl chloride.

Therefore, the above problems can be solved by the means described in the following items.
