Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing static electricity on flooring materials.

In recent years, various flooring materials made of synthetic resins, such as decking materials made of synthetic resins, have become popular and are being installed on the floors of balconies of houses and the like. However, with this type of conventional synthetic resin flooring, pedestrians themselves are generally charged with static electricity due to friction when walking.
The drawback was that electric shocks were generated when touching conductive objects such as metal handrails. For this reason, recently, flooring materials designed to prevent static electricity have been developed by providing conductive material for grounding exposed on the surface of synthetic resin flooring materials, or by forming ridges on conductive soft synthetic resin. However, such a flooring material had the disadvantage that the conductive material on the surface easily peeled off, and it could hardly be said to be advantageous in terms of manufacturing process, cost, or design.

The present invention has been made in view of the above circumstances, and includes a positively charged surface area formed of a charged material located on the positive side of the acrylic resin on the surface of the flooring material, and
By constructing a negatively charged surface region made of a charging material located on the negative side of the vinyl chloride resin on the charging series, and using a novel technical means to prevent charging by neutralizing the opposite static electricity generated by friction. , which attempts to prevent static electricity. Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a perspective view of the most basic embodiment of the flooring material according to the present invention, and FIG. 2 is an enlarged partial sectional view taken along the line in FIG. It is a long plate-like flooring material that uses electrically charged vinyl chloride resin and has a locking edge 4 at one end and an engagement groove 5 at the other end, and has an uneven cross section. By using an acrylic resin or paint that is positively charged by providing a plurality of band-shaped coating layers 7 at intervals on the surface of the flooring main body 6, a positive charge consisting of the surface of the coating layers 7 is formed. Charged surface area 1...
and a negatively charged surface region 2 consisting of the exposed surface of the flooring main body 6 are provided with a surface 3 configured in the form of vertical stripes. Such flooring materials are manufactured by a so-called two-layer extrusion method in which acrylic resin is simultaneously extruded when the flooring material body 6 is manufactured by extruding vinyl chloride resin, or by applying acrylic resin to the surface of the flooring material body 6 that has been prepared in advance. It can be easily manufactured by applying resin.

FIG. 3 is a perspective view of another embodiment of the flooring material according to the present invention, and FIG. 4 is an enlarged partial sectional view taken along the line of FIG. 3, which is similar to the embodiment of FIGS. On the other hand, a floor material main body 60 in the form of a long plate with a clog-shaped cross section is manufactured by extrusion molding using acrylic resin, and a coating layer 70 is formed by applying vinyl chloride resin on the surface in a wood grain pattern. By providing this, a wood grain surface 3 consisting of a positively charged surface region 1 consisting of the exposed surface of the flooring main body 60 and a negatively charged surface region 2 consisting of the surface of the coating layer 70 is provided. It is something that

In the case of the floor materials shown in FIGS. 1 to 4, grooves may be formed in advance on the surface of the floor material main body 6 or 60, and the covering layer 7 or 70 may be buried so that the surface thereof is exposed.

FIG. 5 is a perspective view of yet another embodiment of the flooring material according to the present invention, and FIG. 6 is an enlarged partial sectional view taken along the line in FIG. A floor material body 61 is manufactured, and acrylic resin and vinyl chloride resin are arranged in advance alternately in a rectangular shape so that positively charged surface areas 1... and negatively charged surface areas 2... are formed in a checkerboard pattern. This surface layer member 8 is bonded to the surface of the flooring main body 61 using a sheet-like surface layer member 8 integrally heat-sealed.

As can be understood from the above examples, the flooring material according to the present invention is provided with a coating layer made of acrylic resin on the surface of the flooring material body made of vinyl chloride resin, or
Alternatively, on the contrary, a coating layer made of vinyl chloride resin may be provided on the surface of the floor material body made of acrylic resin, or a sheet-like surface layer member made separately from acrylic resin and vinyl chloride resin may be attached to the floor material body. The gist is that the surface 3 is formed into a desired pattern by positively charged surface areas 1 and negatively charged surface areas 2, by laminating them on the surface of By configuring the surface with an acrylic resin charged surface area that becomes positively charged due to friction with pedestrians and a vinyl chloride resin charged surface area that becomes negatively charged due to friction under the same conditions, a charged array (electrostatic handbook) is created. According to the Society of Electrostatic Engineers (Ohmsha), when a person walks around wearing slippers made of a material that is approximately intermediate between acrylic resin and vinyl chloride resin, such as urethane rubber or polystyrene, the friction caused by that creates a positively charged surface area. 1..., positive static electricity occurs, negatively charged surface area 2
... will generate negative static electricity, but the human body generates the opposite static electricity from the flooring, and the human body's own static electricity is canceled out and electrically neutralized.

According to the charging series, typical charging materials located on the positive side of the polyamide resin forming the positively charged surface area 1 used in the flooring material of the present invention include nylon and polymethyl methacrylate. Typical charging materials located on the negative side of the vinyl chloride resin forming the negatively charged surface areas 2 include polytetrafluoroethylene as well as vinyl chloride.

The embodiment of the present invention uses a combination of acrylic resin and vinyl chloride resin as positively charged material and negatively charged material, respectively, and the floor material body is made of polyvinyl chloride as in the embodiment shown in Figures 1 and 2. In addition, a coating layer made of acrylic (based) resin or paint is said to be the most desirable from various viewpoints such as weather resistance, peeling resistance, strength, productivity, cost, and commercial value.

The positively charged material and the negatively charged material of the present invention can be colorless (semi) transparent, colored (semi) transparent, colorless opaque, or colored opaque, and by appropriately combining these, beautiful Moreover, a surface with a unique pattern can be easily formed.

As described in detail above, the present invention provides a surface area of the floor material with a positively charged surface area formed of a charging material located on the positive side of the acrylic resin on the charging series, and a positively charged surface area formed of a charging material located on the negative side of the vinyl chloride resin on the charging series. By constructing a negatively charged surface area made of a charged material, when a person walks wearing slippers or the like made of a material that is approximately halfway between the two, static electricity opposite to that of the flooring material is generated, which can cause damage to the human body. Since its own static electricity is canceled out and electrically neutralized, it will not cause an electric shock even if it touches a conductive object such as a metal handrail.

In addition, there is no need for a foreign and expensive conductive material for grounding that does not bond well with the flooring itself, so it is superior in terms of peeling resistance, design, and cost, and it also has a surface with a desired pattern. Because it is obtained, it becomes a product with a wide variety and high commercial value, and it is also advantageous in terms of manufacturing method because it can be easily and efficiently manufactured by two-layer extrusion molding, coating, lamination, etc.
etc., the actual benefits are extremely large.
