Description

  The present invention relates to a multifunctional mat that is easy to detach and replace, is excellent in waterproofness and antiallergen function, and is optimal for a house where a pet and a person can live comfortably together, and a construction method using the multifunctional mat.

  In recent years, breeding of pets indoors has increased, and housing construction materials suitable for pet breeding have been developed. In the flooring, wood flooring is slippery and carpet is preferred, but the carpet is entangled with pet hair and cannot be easily removed by vacuum suction. Thus, a proposal has been disclosed in which the surface layer is a group of inclined piles so that pet hair can be efficiently attached and easily removed like the rug described in Patent Document 1. This prevents hair from adhering to the rug and preventing scattering into the room, preventing hair once adhering from adhering again to other fibers such as clothing, and using cleaning means using similar inclined pile groups. This facilitates cleaning and keeps the rug clean.

  Moreover, as a method for constructing a rug, Patent Document 2 discloses a method in which an adhesive tape is attached in advance to the back surface of a tile carpet and laid while connecting adjacent tile carpets. Thereby, simple construction can be performed without soiling the floor surface with an adhesive or being damaged by the organic solvent of the adhesive.

  However, according to the rug, it is possible to take measures against hair loss, but excrement (feces and ticks that cause allergens) such as feces and urine (when pets are kept indoors, they cannot be handled only with urns and toilet articles). Difficult to clean or keep clean. In addition, in the tile carpet construction method, pet manure (particularly liquid) penetrates from the joints and penetrates to the back side, causing problems such as fouling existing flooring and causing corrosion.

The present invention has been made in view of such problems, and is excellent in waterproofness and can inactivate allergen substances caused by mites, pollen, pet hair, sebum (dandruff), etc. It relates multifunctional mat is effective in suppressing the generation, in particular, an object of the invention to provide a construction method using such a multi-function mat.

To achieve the object, the engaging Ru inventions in claim 1, composed of a surface decorative layer of fiber, and an intermediate waterproof layer, which is formed of a foamed synthetic resin having a suction cup function as back surface adsorption layer, the surface A multi-functional mat construction method for laying a multi-functional mat on a floor surface , characterized in that 20-30% by weight of fibers having an anti-allergen function is mixed in the decorative layer on the floor surface. After installing a tape composed of a waterproof layer and an adsorption layer formed of a foamed synthetic resin having a sucker function in advance in a grid-like position at the seam between the multifunctional mats. The multifunctional mat is detachably fixed on the tape so that a plurality of the multifunctional mats are laid while being adjacent to each other .

Multifunctional mat used in the present invention, since the back surface adsorption layer formed of a foamed synthetic resin having a surface decorative layer and the intermediate waterproof layer and sucker function of fiber, surface decorative fibrous suitable for pet rearing Although it is a mat having a layer, even if manure is raised on the mat when it is raised indoors, it does not penetrate downward due to the intermediate waterproof layer. Moreover, since it can be detachably installed on the floor surface by the back surface adsorbing layer, even if it is soiled, it can be easily replaced one by one. Furthermore, the surface cosmetic layer contains 20-30% by weight of the fiber with anti-allergen function in the entire fiber, so it inactivates allergen substances caused by mites, pollen, pet hair, sebum (dandruff), etc. Effective in suppressing the occurrence of allergic diseases.

Then, such a multifunctional mat when laying on the floor surface, the tape comprising a suction layer made of a foamed synthetic resin having a pre-waterproof layer and the sucker function position where the multifunction mat seam between adsorption Since the layers are arranged in a grid pattern facing the floor, the tape with the waterproof layer is always positioned at the joint between the multifunctional mats , and the liquid leaked from the joint that cannot be waterproofed by the intermediate waterproof layer Can be prevented, and existing flooring can be prevented from being soiled or corroded. Further, even when the tape is previously set on the floor surface, the surface is a waterproof layer and has no adsorptivity, so that the adsorbability is not deteriorated due to contamination like a double-sided tape.

  Embodiments for carrying out the present invention will be described below with reference to FIGS. Of course, the present invention is not limited to the description of the present embodiment.

  The multifunctional mat 1 according to the present invention includes a surface decorative layer 11, an intermediate waterproof layer 12, and a back surface adsorption layer 13, and the surface decorative layer 11 is a carpet made of fibers, so that it has excellent soundproofing properties compared to wood flooring. In winter, it prevents your feet from getting cold, and your pet will not slip even when walking, but the texture and manufacturing method are not particularly limited. Moreover, 20-30 weight% consists of the fiber which has an anti-allergen function among the whole fibers aiming at an anti-allergen effect and a deodorizing effect.

  As the fiber having an anti-allergen function, (1) the fiber itself has an anti-allergen function: for example, a fiber made of an acrylate fiber using an anionic functional group, and (2) a normal fiber with an allergic deactivator. Treated with: for example, the surface of fibers such as cotton, hemp, wool, silk, rayon, nylon, polyester, polypropylene, acrylic, etc., treated with an allergy deactivator such as zirconium salt, tannin, catechin, etc. .

  The anti-allergen effect and deodorizing effect are not practical enough if the amount of the fiber having an anti-allergen function provided in the surface decorative layer 11 is less than 20% by weight of the whole fiber, and even if it exceeds 30% by weight, it is practical. Since the above performance does not change much and the cost increases, 20 to 30% by weight is preferable. In addition, as fibers other than those having anti-allergen function, fibers that are generally used for carpets and the like may be used, and cotton, hemp, wool, silk, rayon, nylon, polyester, polypropylene, acrylic, etc. are used. It is done.

  The intermediate waterproof layer 12 is on the lower surface side of the multi-function mat 1, so that water overflowing on the multi-function mat 1 or pet urine penetrates and soils the existing floor 3, which is a base, and becomes unclean. It is possible to prevent the state of becoming or corroding. The intermediate waterproof layer 12 is preferably made of a flexible material that is easy to follow along the floor surface 3 as a floor material. For example, a sheet or film of a synthetic resin such as polyethylene, polypropylene, polyvinyl chloride, EVA (ethylene-vinyl acetate copolymer), or the like. Is used.

  The back surface adsorbing layer 13 is provided to fix the multifunctional mat 1 to the floor so as to be detachable. The backside adsorption layer 13 has a sufficient fixing force to prevent the multifunctional mat 1 from moving or floating, and like a conventional double-sided tape. When it is peeled off, there is no danger of peeling off the coating film on the surface of the existing flooring. The back surface adsorption layer 13 is made of a foamed synthetic resin that foams acrylic, urethane, ethylene-vinyl acetate, or the like and has a sucker function with minute bubbles. Further, the arrangement and shape of the back surface adsorption layer 13 are particularly limited, for example, the entire surface of the back surface of the multifunctional mat 1, a field shape with a certain interval, a band shape (FIG. 1), and only one part such as a quadrilateral. It is not something.

  As the dimensions of the multifunctional mat 1, vertical and horizontal are about 300 mm square to 600 mm square, and the thickness is about 3 mm to 10 mm, which is the same as that of a general tile carpet.

  The tape 2 used when constructing the multifunctional mat 1 on the floor surface 3 is composed of a composite of a waterproof layer 21 and an adsorption layer 22. The waterproof layer 21 is waterproof, and the back surface adsorption layer 13 disposed on the back surface of the multifunctional mat 1 is in close contact and firmly fixed, and forms a smooth surface so that it can be easily detached. The foamed synthetic resin is used in the same manner as the back surface adsorbing layer 13, but it is preferable that the tape itself does not have a difference in level, and a thin floor is obtained to provide a floor that is easy to walk without being uneven during construction. For example, about 10 to 40 μm The waterproof layer 21 made of a PET resin film and the adsorption layer 22 made of an acrylic foam resin of about 200 μm are integrated to have a thickness of about 200 to 400 μm, and a width of around 50 mm is preferable in order to have sufficient fixing strength. .

As shown in FIG. 2, the tape 2 is previously installed with the adsorbing layer facing the floor surface at a position that becomes a joint when the multifunction mats 1 are installed adjacent to each other on the floor surface 3. After the tape 2 is installed on the entire construction surface, as shown in FIG. 3, when the multi-function mat 1 is placed on the center line so that the four sides of the multi-function mat 1 are aligned, the back surface adsorption layer 13 of the multi-function mat 1 is formed. It adheres to the waterproof layer 21 and is adsorbed and fixed detachably. Since the surface of the tape 2 is the waterproof layer 21 and has no adsorptivity and is difficult to get dirty with a smooth surface, there is no problem even if the tape 2 is left on the entire floor surface 3 in advance for a while.

  The back surface of the multifunctional mat 1 is placed on the smooth waterproof layer of the tape 2 by placing the four peripheral end surfaces of the multifunctional mat 1 on the substantially central line in the width direction of the tape 2 installed in a grid pattern on the floor surface 3. The adsorption layer 13 is closely attached and fixed. Multiple multifunctional mats 1 are laid next to each other, so that they can be prevented from floating or moving in the horizontal direction, and can be removed and removed in units of one sheet, so they can be easily replaced when wet or dirty. Can do.

  The multifunctional mat of Example 1 has a first layer from the surface side: a raised nonwoven fabric, 70% by weight of polyester fiber, 30% by weight of an allergen acrylate fiber (surface decorative layer), a second layer: a polyester nonwoven fabric, 3rd layer: SBR resin backing, 4th layer: polyethylene resin (waterproof layer), 5th layer: polyester nonwoven fabric (acrylic resin coated base), 6th layer: acrylic resin foam layer (back surface adsorption layer) It consists of 6 layers, is about 6.5mm thick and 450mm square.

The multifunctional mat of Example 2 has a three-layer structure in order to reduce the thickness as compared with Example 1. First layer from the surface side: felted nonwoven fabric, 80% by weight of polyester fiber, 20% by weight of anti-allergen acrylate fiber (surface decorative layer), second layer: polyethylene resin (waterproof layer), third layer: acrylic It consists of a resin foam layer (back surface adsorption layer) and is about 4 mm thick and 450 cm square.
