Description

  The present invention relates to a flooring, and more particularly to a wooden flooring obtained by applying a mirror finish to the surface of a base substrate.

  Wood-based flooring is easy to clean and clean, and the use of Western-style living is increasing, and its use is rapidly expanding as a flooring material mainly in apartment buildings. However, with the depletion of timber resources worldwide, it has become difficult to obtain solid timber, and the price has been rising, so various things such as plywood, laminated wood, medium density fiberboard (MDF), particle board, etc. A composite flooring finished by applying surface decoration to a wooden base material is popular.

  On the other hand, in recent years, sickness due to allergens such as dead mites, dung, house dust, symptom such as hay fever due to allergens such as pollen allergens such as pollen allergens become a social problem, Curtains have been developed in which a special processing agent that suppresses the activity of pollen allergens is coated very thinly and preventive measures such as hay fever are taken.

  Also, in the residential field, floor materials are known which are finished by mirror-finishing the surface of the flooring material and coated with a special finishing agent that suppresses allergen activity in the mirror-finishing paint. Floor materials with allergen countermeasures, for example, are easily carried indoors in order to suppress allergen activity such as pollen that has been carried into the room by the wind or brought in with human clothes and dropped on the floor. It can be taken as a preventive measure.

  On the other hand, JP-A-2004-90319 discloses a decorative material in which a wear-resistant resin layer containing an antiwear agent is provided on a base material, and a matte resin layer containing a matting agent is provided on the wear-resistant resin layer. Further, there is disclosed a cosmetic material obtained by laminating a wear-resistant resin layer through a smoothing resin layer that smoothes the rough surface, and further laminating a gloss improving resin layer partially on the matte resin layer.

  Further, it is said that an extender pigment may be contained in the smoothing resin layer, and further, a design property is further improved if a solid pattern layer or a pattern layer is provided between the base material and the wear-resistant resin layer. In addition, if the pattern of the luster-improving resin layer is aligned with the pattern of the pattern layer, the design is further improved, and the gloss mat (surface) is combined with wear resistance and scratch resistance that does not damage other contact objects. The effect is described when it can be set as the cosmetic material excellent also in the design feeling by a gloss change pattern.

JP 2004-90319 A

  For example, in floor materials where hay fever countermeasures are taken, the mirror finish paint is applied over the transparent undercoat, but it contains a chemical that imparts properties to the surface. Therefore, the glossiness of the mirror surface is lower than the glossiness of the transparent undercoat film having a single composition, so that there is a problem that the glossiness is different at various locations on the surface of the flooring and uneven glossiness occurs.

  On the other hand, the decorative material described in Patent Document 1 is excellent in design that expresses a pseudo three-dimensional effect of, for example, a wood grain conduit pattern by a gloss mat, and can be used as a flooring. There is no description of imparting surface properties such as suppressing the activity of pollen allergens to the membrane.

  The present invention has been made in view of the above-mentioned background art, and its purpose is to make the flooring mirror-finished and have excellent design, and on the flooring surface, pollen allergens, mite carcasses, dung, house dust It is providing the flooring which provided surface characteristics, such as exhibiting the activity suppression effect of various allergens.

  In order to solve the above-mentioned problem, the flooring according to the first aspect of the present invention provides an undercoat mirror surface coating layer by applying an undercoat mirror surface coating to a base substrate, and surface characteristics on the undercoat mirror surface coating layer. In the floor material formed by applying a top coat mirror paint containing an imparting agent, the gloss of the undercoat mirror paint layer is lowered with respect to the finished gloss of the floor material after the top coat mirror paint is applied. To do.

  Examples of the base substrate include various wood substrates such as plywood, laminated wood, medium density fiberboard (MDF), particle board, and wood plastic board (WPB). Among them, a thick decorative plywood is preferably used because it has excellent strength, is easily available, and has good workability.

  As the undercoat mirror surface paint to be undercoated on the base substrate, a paint made of a thermosetting resin that forms a transparent resin layer is used. As the thermosetting resin, a polyester resin, a vinyl ester resin, and a thermosetting acrylic resin can be used alone or in a mixture of two or more of these.

  Polyester resins are thermosetting and synthesized by the condensation reaction of unsaturated dibasic acids such as maleic anhydride and saturated dibasic acids such as phthalic anhydride and glycols, and unsaturated in the molecule. It has a bond and an ester bond. Usually, this resin is blended with a styrene monomer, an acrylic monomer, or the like as a crosslinking agent, and what is called an unsaturated polyester resin is used, but the form is not particularly limited.

  As the vinyl ester resin, a bisphenol type vinyl ester resin or a novolac type vinyl ester resin or a mixture of both can be used. Here, the bisphenol-type vinyl ester resin is an addition reaction product of a bisphenol-type epoxy resin and an acid, and both have reactive unsaturated groups only at both ends. As the bisphenol type epoxy resin, various types such as a bisphenol A type, a bisphenol AD type, a bisphenol S type, and a bisphenol F type can be used. Usually, this vinyl ester resin is blended with a styrene monomer, an acrylic monomer or the like as a crosslinking agent, but the form is not particularly limited.

  As the thermosetting acrylic resin, what is called an acrylic syrup composed of a mixture of two or more of methyl methacrylate monomer, polyfunctional acrylic monomer or prepolymer, or polymer is usually used as thermosetting type. Although used, the form is not particularly limited.

  As the top coat mirror paint used by blending the surface property imparting agent, as with the undercoat mirror paint, a paint that forms a transparent resin layer, that is, a polyester resin, a vinyl ester resin, a thermosetting acrylic resin alone or A paint composed of a mixture of two or more of these is used.

  Examples of the surface property-imparting agent include special processing agents that suppress the activity of various allergens such as house dust and pollen allergen, and antiwear agents.

  In the flooring according to the first aspect of the present invention, the glossiness of the undercoat mirror coating layer includes the top coating mirror coating layer and the undercoat mirror coating layer that can be seen through the top coating mirror coating layer. Since it is lower than the glossiness, there is no difference in gloss, and gloss unevenness is prevented from occurring on the flooring surface. And the floor material excellent in the designability with the calm feeling of transparency can be obtained.

  For example, if a special finishing agent that suppresses the activity of pollen allergens is mixed and top-coated with a mirror finish, the flooring is given surface characteristics that suppress the activities of pollen that falls on the floor or allergens such as house dust. Therefore, it can be an easy indoor hay fever prevention measure in the pollen season.

  Furthermore, by using a special processing agent that suppresses the activity of pollen allergens together with a curtain coated with a very thin layer, preventive measures such as hay fever in the room can be made more reliable.

Sectional drawing which shows the flooring of this invention typically.

  Hereinafter, embodiments of a flooring according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view of a flooring of the present invention in which a decorative plywood made by applying a decorative sheet on the surface of a thick plywood is used as a base substrate 4 and an undercoat mirror coating layer 2 and an overcoat mirror coating layer 1 are provided thereon. FIG.

  As shown in FIG. 1, the surface of the decorative plywood used as the base substrate 4 is solidly coated with a colored cosmetic undercoat for improving the design of a pattern such as a wood grain pattern, and a cosmetic undercoat layer 3 is provided. It has been. Then, an undercoat mirror surface coating layer 2 is applied on the cosmetic undercoat layer 3 to provide the undercoat mirror surface coating layer 2, and a top coating mirror surface coating material containing the surface property imparting agent 5 is further applied to provide the top coating mirror surface coating layer 1.

  Here, the finished glossiness of the flooring material is the glossiness including the topcoat mirror surface coating layer 1 and the undercoat mirror surface coating layer 2 that can be seen through the topcoat mirror surface coating layer 1. In the flooring material of the present invention, The glossiness of the undercoat mirror surface coating layer 2 is made lower than the glossiness of the finished flooring.

  The glossiness described above is measured by a method defined in Japanese Industrial Standard (JIS). For example, the glossiness of the topcoat mirror coating layer 1 is 40 to 60, and the glossiness of the undercoat mirror coating layer 2 is 20 to 60. Setting and lowering of the glossiness of the undercoat mirror surface coating layer 2 does not cause a difference in glossiness, and prevents irregular reflection from the ground, thereby eliminating the occurrence of uneven glossiness on the floor material surface.

  The glossiness of the topcoat mirror coating layer 1 and the glossiness of the undercoat mirror coating layer 2 are within the above numerical range, and the desired glossiness of the finished flooring material is obtained by lowering the glossiness of the undercoat mirror coating layer 2. A flooring material having no gloss unevenness and having a calm and transparent design can be obtained.

  At this time, for example, if the top coat mirror surface coating layer 1 is formed by blending the top coat mirror surface paint with a special processing agent that suppresses the activity of allergen as the surface property imparting agent 5, pollen carried by the wind from the outside, and human clothes In addition, in order to suppress the activity of allergens such as pollen that has been brought in and fallen to the floor, or house dust, it can be a simple indoor hay fever prevention measure.

  In addition, although embodiment mentioned above described the example which used the thick decorative plywood as a base substrate, it is not restricted to a decorative plywood, You may use wooden boards, such as a particle board and a medium density fiber board (MDF). As described above, the floor material according to the present invention can be freely changed in design and belongs to the technical scope of the present invention unless departing from the scope of the claims.
