Abstract

PURPOSE:To obtain a bath mat which protects a user against slippage and is highly weather-proof by adhering a polyolefin foam sheet with continuous foams to the rear ground-contacting area of a thermally plastic resin foam plate containing independent foams. CONSTITUTION:Polyethylene foamed products with independent foams are laminated to form a thermoplastic resin foam plate 1. In addition, plate-like legs 11, each consisting of a foamed product based on a single material are arranged side by side along one side and a polyolefin foam sheet 2 containing a continuous foams is adhered to the entire ground-contacting surface of the leg 11. The foam sheet 2 preferably is formed by adhering two sliced pieces of foam sheet with a skin attached to the one surface together in the center of the thickness with the sliced surface 21 allowed to face outward. The polyolefin foam sheet used is a foam sheet based on polypropylene resin material. The bath mat thus obtained is highly slip-proof and also highly weather-proof.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath mat placed on the floor of a bathroom.

0002

[Prior Art] Conventionally, bath mats made of thermoplastic resin foam boards with closed cells have been widely used, and the technology to make them anti-slip is to cover almost the entire back surface of the foam sheets. A technology for bonding nonwoven fabrics made of polyamide fibers and polyvinylidene chloride fibers was developed in 1983-2.
It is described in Publication No. 3444.

0003

[Problems to be Solved by the Invention] However, in the case of the above-mentioned conventional products, there was a problem in that the anti-slip effect was low. An object of the present invention is to solve the above-mentioned conventional problems and provide a bath mat having excellent anti-slip effect and weather resistance.

0004

[Means for Solving the Problems] The gist of the present invention is that a polyolefin foam sheet having open cells is fixed to the ground surface on the back side of a thermoplastic resin foam board having closed cells. be.

[0005] Polyolefin foam sheets used in the present invention include polyethylene, polypropylene,
Examples include sheets formed by foaming olefin copolymers such as ethylene-vinyl acetate copolymers, or mixtures thereof as resin materials.

[0006] It is preferable that an antibacterial and antifungal agent be kneaded into the polyolefin foam sheet in advance in order to prevent mold and the like from adhering to the surface of the polyolefin foam sheet from the environment in which it is used, thereby reducing the anti-slip effect.

[0007]

[Function] Since the tread surface of the bath mat of the present invention is made of a polyolefin foam sheet having open cells, the suction effect of the open cells works, making it difficult to slip even on tiles covered with soap.

[0008]

Embodiments An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a perspective view showing an embodiment of the bath mat of the present invention, in which 1 is a thermoplastic resin foam board having closed cells. The thermoplastic resin foam board 1 is composed of three laminated sheets of closed-cell polyethylene foam having an expansion ratio of 30 times and a thickness of 4 mm. On the back side of the foam board 1, a plurality of plate-shaped legs 11 made of foam of the same material are arranged in parallel along one side, and a polyolefin foam sheet 2 having open cells is adhered to the entire ground surface of the legs 11. has been done. This foam sheet 2 has a foaming magnification of 32 times and a thickness of 2 mm.
It is a skinned foam made of ethylene-vinyl acetate copolymer having open cells.

In Example 2, a single-sided skinned foam was obtained by slicing an ethylene-vinyl acetate copolymer skinned foam having open cells with a foaming ratio of 32 times and a thickness of 4 mm into two pieces at the center of its thickness. The sheets are glued together with their sliced sides 21 facing outward.

[0010] If the bath mat is in the form of a flat plate without legs, it is preferable to adhere a foam sheet having open cells to the entire surface of the bath mat. Examples 1 and 2
For each comparative example in which other anti-slip materials as shown in Table 1 were used instead of the polyolefin resin foam sheet having open cells, one foot was placed on the upper surface of an FRP bathroom floor that had been actually sprinkled with water. Table 1 summarizes the results of measuring the amount of movement in the horizontal direction. Furthermore, the dynamic friction coefficient is 5% by weight.
This shows the coefficient of kinetic friction between the glass plate and the glass plate on which soapy water is poured.

Note) ◎: No deviation, ○: Small deviation, △: Large deviation. *1: Yellowed and deteriorated due to sunlight and lost its shape in 7 days. As mentioned above, it can be seen that the Examples and the polyurethane foam boards are superior in anti-slip effect compared to other comparative examples, but among them, the polyurethane foam boards are inferior in weather resistance and lack practical use.

[0013]

[Effects of the Invention] Since the bath mat of the present invention is constructed as described above, it has an excellent anti-slip effect and also has weather resistance.

Claims (2)

[Claims] 1. A bath mat characterized in that a polyolefin foam sheet having open cells is fixed to the ground surface on the back side of a thermoplastic resin foam board having closed cells. 2. The bath mat according to claim 1, wherein the polyolefin foam sheet having open cells has a sliced surface on at least one surface and is fixed with the sliced surface facing outward.
