Description

Floor mat {floor mat}

The present invention relates to a floor mat comprising a top plate and a bottom plate, and more particularly, a bottom plate corresponding to a bottom surface of a vehicle, an office, a kitchen, etc. is composed of a polypropylene foam and a thermoplastic polyurethane film, , A cushion feeling, a durability and a non-slippery property.

In general, the floor of a vehicle such as a passenger car, a van, a truck, etc. is prevented from being scattered to the surroundings by the soil, dust, and other foreign matter adhering to the passenger's shoes, thereby preventing the carpet or seat of the floor from being contaminated or soiled A mat for the vehicle is laid down.

Carpet-type mats have been most widely used for such vehicle matrices, and are generally formed of a structure in which a carpet having a certain length of cilia is formed on the upper surface of a lower plate formed of polyvinyl chloride (PVC) or rubber.

However, in the conventional vehicle mat constructed as described above, since the lower plate, which is in contact with the bottom of the vehicle, is made of polyvinyl chloride (PVC) or rubber and the frictional force is not large, when the user steps on the mat for the vehicle, do. When the vehicle mat slides on the floor of the vehicle, the user who stands on the vehicle mat may fall, and if the mat for the vehicle can not maintain the fixed position and the state of the mat is maintained for a long time, the overall shape may be deformed.

In addition, when the vehicle is running, noise and vibration are introduced into the vehicle interior through the floor of the vehicle. When the bottom plate of the vehicle mat is made of polyvinyl chloride (PVC) and rubber, the noise introduced through the floor of the vehicle is transmitted to the bottom plate of the vehicle mat There is a problem that amplification occurs.

In addition, the bottom plate of the rubber material has a strong smell unique to the rubber that remains in the interior of the vehicle or inside the vehicle for a long time. In addition, the flooring material of polyvinyl chloride (PVC) not only contains a chlorine component harmful to human body, but also induces environmental pollution such as dioxin emission during incineration, so that the indoor floor material is gradually being regulated as an indoor material.

In order to solve the above problems, the entire mat for a vehicle may be made of a fabric such as a nonwoven fabric. However, when the entire mat for a vehicle is made of a fabric, not only the manufacturing cost is increased, but also when liquid such as drinking water is poured onto the mat for a vehicle So that there is a problem of contamination.

In order to solve these problems, the applicant of the present invention has proposed a vehicle floor mat comprising a bottom plate made of a nonwoven fabric, a non-slip part formed on the bottom surface of the nonwoven fabric, and an upper plate made of a ciliary layer and a waterproof layer in Korean Registered Utility Model No. 0-0474343 It has been found that it has excellent noise barrier properties and non-slip property by the proposal, but it is disadvantageous in that it is not easy to dry due to the nonwoven fabric material during the washing of the mat, thus frequent washing is difficult. In addition, since the drying cycle is long, the non-slip portion can not maintain a clean state due to a long washing cycle, so that the grounding force becomes weak. Therefore, in a LPI (Liquefied Petroleum Injection) vehicle having a bottom of the vehicle made of PVC emboss or TPO emboss, There is a disadvantage in that the mattress phenomenon occurs due to insufficient castability. Further, when an excessive impact is generated during use of the mat, the cushion feeling is not good and the impact resistance is poor.

Therefore, the object of the present invention is to solve the problems of the above-mentioned conventional mat. By constituting the lower plate of the mat by the polypropylene foam and the thermoplastic polyurethane film, the weight of the floor mat can be reduced, Which is excellent in cushioning feeling, durability and impact resistance, and can also reduce noise and vibration entering the room through the floor of the vehicle.

In addition, since the bottom surface of the polypropylene foam and the thermoplastic polyurethane film is further provided with a non-slip portion, the durability and non-slip property of the mat are also improved.

The floor mat of the present invention includes a bottom plate that is seated on a floor, an upper plate that is stacked on the upper portion of the lower plate, and a non-slip portion that protrudes downward from the bottom plate, A polypropylene foam laminated on the bottom of the polyethylene film, and a thermoplastic polyurethane film laminated on the bottom of the polypropylene foam.

Wherein the top plate is made of any one of nylon carpet, polypropylene carpet, and PET carpet.

The thickness of the polyethylene film is 50 to 100 탆, and the thickness of the polypropylene foam 120 is 0.3 to 2 cm.

The thickness of the thermoplastic polyurethane film is 50 to 100 탆, and the thermoplastic polyurethane film is hydrophobically treated.

The non-slip portion is formed of silicon material and has an area of 20 to 80% of the total area of the lower plate.

According to the present invention, there is an excellent durability, a cushion feeling and a slip prevention effect, a drying time after washing can be shortened, a pleasant indoor environment can be maintained, and the mud bottom or surface can be easily cleaned.

2 is a side sectional view of the floor mat according to the present invention;
3 is a bottom perspective view of a floor mat according to the present invention;
4 is a side cross-sectional view of another embodiment of the present invention;

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The floor mat according to the present invention is installed on the floor of the vehicle interior space or installed on the indoor floor of the office so as to collect soil or dust on the user's shoes and to absorb part of the noise of the vehicle or office. 1 and 2, the upper plate 200 and the lower plate 100 are stacked in the vertical direction and the lower plate 100 is protruded downward on the bottom surface of the lower plate 100 to prevent the floor mat 10 from slipping from the bottom surface And a joining member 400 mounted on the edge of the upper plate 200 and the lower plate 100 to couple the upper plate 200 and the lower plate 100 to each other.

When the lower plate 100, which is in contact with the bottom surface of a vehicle or an office, is made of synthetic resin such as PVC or rubber as in the conventional art, noise and vibration introduced through the bottom surface can not be absorbed and the quietness is lowered. It is disadvantageous in that it is not good in usability due to a long drying time after washing and can not sufficiently absorb excessive shock which occurs frequently during use.

Therefore, in order to overcome all of these disadvantages, the present invention is characterized in that the lower plate 100 is made of a polyethylene film 110, a polypropylene foam 120 and a thermoplastic polyurethane film (TPU) 130 . That is, when the lower plate 100 is composed of the polyethylene film 110, the polypropylene foam 120, and the TPU film 130, noise and vibration generated from the bottom surface can be absorbed, Shock can also be absorbed and, most notably, the drying time after washing is remarkably shortened, so that a comfortable indoor environment can be maintained through frequent washing. In addition, light weight can be ensured and handling thereof is facilitated.

First, the polypropylene foam 120 constituting the lower plate 100 is a thermoplastic synthetic resin excellent in chemical resistance and heat resistance, and is lightweight, has good elastic recovery, is easy to dry after washing, and has high heat resistance, It is possible to prevent nonconformity such as curling and shrinkage after dipping into the mat 10, which is superior to other polyethylene foam or polyurethane foam as a floor mat.

Such a polypropylene foam 120 can selectively use a sheet produced by electron beam crosslinking foaming or chemical crosslinking foaming. Briefly, the electron beam crosslinking foaming sheet accelerates electrons under a high voltage by an electron beam irradiating apparatus, The accelerated electron beam is irradiated on a solid sheet to cause a chemical reaction to effect crosslinking and foaming. Ethylene-vinyl acetate copolymer (EVA) is added to the electron beam crosslinking foaming as an additive It is also included to adjust the physical properties. The electron beam crosslinked foam sheet is characterized in that the surface state and cell are uniform as compared with general chemical crosslinking foaming, and the strength, water resistance, adhesiveness, heat insulation and warming property are improved as compared with general crosslinked foam, And has a characteristic of preventing slippage by the frictional force of the surface thereof, thereby preventing the mat from sliding due to the frictional force with the bottom surface. In contrast, chemical crosslinking foaming is characterized in that crosslinking and foaming are carried out by a crosslinking agent and a foaming agent. The chemical crosslinking foam sheet is characterized in that it can produce a relatively thick product, has a strong physical property, and is excellent in heat insulation and insulation. Accordingly, in the present invention, various types of polypropylene foam 120 are selected and used as needed.

However, the polypropylene foam 120 may be damaged easily due to external scratches or impacts, which is disadvantageous in that it is poor in durability. In order to overcome such disadvantages, the polypropylene foam 120 has polyethylene And the TPU film 130 is arranged on the bottom surface of the film 110.

The polyethylene film 110 adhered to the surface of the polypropylene foam 120 enhances the durability of the polypropylene foam 120 and also functions as a waterproof layer. That is, the polyethylene film 110 prevents the stress of the upper plate 200 from being transmitted to the polypropylene foam 120, and is transmitted to the polyethylene film 110 when the upper plate 200 undergoes shrinkage expansion and deformation The polypropylene foam 120 and the bottom surface of the vehicle or the floor of the vehicle are prevented from being contaminated when the liquid is poured into the upper plate 200 during use so as not to transmit frictional force to the polypropylene foam 120, The thickness is not limited.

The polyethylene film 110 and the polypropylene foam 120 may be formed by an extrusion molding method or a calendering method. The extrusion molding method may be a method of extruding the polyethylene film 110 and the polypropylene foam 120 using an extrusion molding machine, And the calendering method is a method in which a polyethylene film 110 and a polypropylene foam 120 are passed through a heated rolling roller, rolled, molded to have a predetermined width and thickness, . If the pressure of the pressure roller exceeds 6 kg / cm 2, the material of the foam material is excessively heated so that the upper plate 200 and the lower plate 100 are combined with each other, Or when the pressure is increased at a high temperature, the foam may be compressed and the cushioning property may be deteriorated.

The thermoplastic polyurethane film (TPU) film 130 adhered to the bottom of the polypropylene foam 120 not only improves the durability of the polypropylene foam 120 but also enhances the contact force with the bottom surface of the vehicle or the floor of the office Imparts non-slip properties, and improves dryness after washing. At this time, the filling of the polypropylene foam 120 and the TPU film 130 may be performed by extrusion or calendering.

The TPU film 130 is a restorable functional film and has durability to be restored without being torn by external stretching or impact. That is, the TPU film 130 has a high elasticity, so that it is not only resistant to external impact but also low temperature embrittling temperature, so that it can be used in extreme weather conditions and oil resistance is excellent. In addition, it is characterized by excellent elongation as well as excellent elasticity. Therefore, the TPU film 130 having such abrasion resistance, durability and high elasticity is applied to the polypropylene foam 120 to improve the durability of the polypropylene foam 120 and also to improve the cushioning and non-slip properties of the mat 10 .

On the other hand, the TPU film 130 may develop a phenomenon in which the TPU film 130 is floated in the state of the material. To prevent this, it is preferable to perform a hydrophobicity treatment. The hydrophobic treatment may be performed by applying a surface treatment to the TPU film 130 using a compound or a mixture of compounds selected from the group consisting of fluorine compound and non-fluorine compound materials, silicone / siloxane, acrylic compound, , Coating treatment, and the like. For example, when the hydrophobic treatment is coated, the water-repellent coating agent is heated to a temperature of 170 to 180 DEG C to perform coating treatment. Such a water-repellent coating agent uses an organic fluorine-based water-repellent coating agent and is not limited to the composition of the specific compound .

Therefore, in order to remove only the dust adhering to the bottom surface of the mat (10), the TPU film (130) of the present invention does not allow water to pass through the hydrophobic treatment. So that it is possible to wash and dry easily, and it is possible to frequently clean the bottom surface, thereby preventing the below-mentioned non-slip part 300 from being weakened by dust or the like have.

The thickness of the polyethylene film is 50 to 100 탆, the thickness of the polypropylene foam 120 is 0.3 to 2 cm, and the thickness of the TPU film 130 is 50 to 100 탆 , The durability of the polypropylene foam 120 can not be compensated for when the thickness of the polyethylene film 110 or the TPU film 130 is thinner than 50 탆 and sufficient durability can be provided when the thickness exceeds 100 탆 However, the manufacturing cost is increased, and the thickness thereof causes poor lightness and handling property. If the thickness of the polypropylene foam 120 is less than 0.3 cm, the cushioning and impact resistance are not good. If the thickness is more than 2 cm, the thickness of the mat becomes too thick and the handling is not easy.

When the lower plate 100 of the mat 10 is composed of the polyethylene film 110, the polypropylene foam 120 and the TPU film 130 as described above, excellent cushion feeling, water repellency, dry laundering, Durability and impact resistance.

As the top plate 200 of the present invention, a carpet can be used. By using the carpet, nylon, polypropylene or polyethylene terephthalate and a carpet made of polyethylene terephthalate (PET).

The thickness of the top plate 200 can be set freely within the range that the use of the floor mat 10 (contaminants or moisture absorption, cushioning, bottom surface protection, etc.) or function can be achieved, To 3 cm.

3, a synthetic resin waterproofing layer 110 formed of a polyethylene film, a polypropylene film, or the like is further attached to the bottom surface of the carpet 200. When a liquid or the like is poured into the mat 10, It is possible to prevent the liquid from being absorbed by the lower plate 100. The material of the synthetic resin waterproof layer 110 is not limited.

The non-skid portion 300 provided on the bottom surface of the lower plate 100 so that the lower plate 100 does not slip on the floor is preferably made of silicon having high frictional force and high flexibility and elasticity. There is an advantage that the non-slip portion 300 of the silicone material is brought into contact with the bottom surface of the vehicle or office, and the slipping of the mat 10 on the floor surface is remarkably reduced.

At this time, even though the non-skid portion 300 protrudes downward from the bottom surface of the lower plate 100, the lower plate 100 is formed of a polyethylene film 110, a polypropylene foam 120 and a TPU film 130, The TPU film 130 is brought into contact with the bottom surface of the bottom plate 100. In this case, since the conventional bottom plate 100 is made of a nonwoven fabric or the like The non-slip property is remarkably superior to that of the mat 10.

4, the shape of the non-skid portion 300 may be a downwardly convex dot shape or a downward hemispherical shape so that the user may feel a slight cushion feeling when the user touches the floor mat 10 , And a plurality of them may be arranged on the bottom surface of the lower plate 100 at regular intervals. When the non-slip prevention part 300 is formed in a hemispherical shape, the contact area between the bottom surface of the non-slip part 300 is narrowed. Therefore, when the downward external force is applied, a large amount of deformation in the vertical direction is secured. There is an advantage that the cushion feeling can be felt more in proportion to the deformation amount of the non-slip part 300. [ In addition, since the resilient object has the best restoring force in the spherical shape, when the non-slip prevention part 300 is formed in a hemispherical shape, the downward external force, that is, the restraining force of the occupant, .

5, the non-skid portion 300 may be formed in a shape covering the entire bottom surface of the lower plate 100, that is, the entire bottom surface of the lower plate 100, The non-skid portion 300 is formed in a closed curve or a closed polygonal shape so that the bottom surface of the lower plate 100 is closely packed so that a plurality of the non- . For example, the non-skid portion 300 may be formed in a checkerboard shape having a plurality of horizontal lines and a plurality of vertical lines, that is, a plurality of rectangles connected in a horizontal and vertical direction. When the isolation space 310 is secured as described above, the effect of blocking noise and vibration from the floor is further enhanced.

In addition, the non-slip portion 300 may be formed of a honeycomb pattern, a ring pattern, or the like, and the shape of the non-slip portion 300 is not limited as long as it can impart non-slip property to the lower plate 100.

It is most preferable that the non-slip portion 300 is formed to be 20 to 80% of the total area of the lower plate 100. When the non-slip portion 300 is formed with less than 20% When the area of the non-slip portion 300 is more than 80% of the total area of the lower plate 100, the non-slip portion 300 may be prevented from being slid during the continuous use, Dust is easily adhered to the floor mat 10, which leads to weakening of the grounding force, and it is inconvenient to frequently clean the floor mat 10, and the manufacturing cost is increased.

In the present invention, the upper plate 200 and the lower plate 100 are coupled to each other by a coupling member 400 whose cross section is formed in a 'C' shape so as to surround the edges of the upper plate 200 and the lower plate 100 . That is, after the coupling member 400 surrounds the upper plate 200 and the lower plate 100, the coupling member 400 sticks the upper plate 200 and the lower plate 100 together.

In this case, there is no harmfulness and durability is much higher than when the upper plate 200 and the lower plate 100 are bonded by an adhesive, and a large number of the floor mats 10 are connected to each other It is possible to further increase the dignity of the product, but this is not a limitation, and it is of course also possible to use an adhesive to bond the product.

As a result, the floor mats according to the present invention are designed so that the floor mats 10 for slip prevention are lightweight, easy to clean and dry, and can withstand the frequent excessive shocks during use of the floor mat 10 .

Although the present invention has been described with reference to the accompanying drawings and the preferred embodiments described above, the present invention is not limited thereto but is limited by the claims of utility model registration described later. Accordingly, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the following claims.
