[Detailed description of the invention]

[0001]

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

[0002]

2. Description of the Related Art PVC foam mats have been used as bathroom mats because they have a large effect of blocking heat, water and water vapor, are lightweight, have excellent flexibility and cushioning properties, and are easy to use. The conventional PVC foam mat is a simple PVC foam alone or a laminate.

[0003]

However, in the above prior art, the tensile strength is weak due to its structure, and problems such as tearing and tearing due to the displacement of the chair on the mat are liable to occur, resulting in severe early damage.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a mat for a PVC foaming bathroom which can improve strength while maintaining ease of use. It is.

[0005]

In order to achieve the above-mentioned object, a technical measure made by the present invention is to use a blowing agent of PVC100.
A plain woven or knitted fabric made of desired fibers is narrowed between unfoamed upper and lower PVC sheets obtained by adding 3 to 7 parts by weight to 3 parts by weight, and the upper and lower PVC sheets are increased by 2 to 6 times. That is, the above-mentioned plain woven fabric or knitted fabric is tightly adhered to the entire surface by the upper and lower PVC foam layers which are spatially foamed at a magnification to form a bathroom mat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, A is a bathroom mat of the present invention, which is composed of upper and lower PVC foam layers 1 and 2 and a plain woven or knitted fabric 3.

The PVC foam layers 1 and 2 are made of PVC resin 100
A desired amount of a necessary additive such as a plasticizer and a stabilizer is added to a part by weight, and 3 to 7 parts by weight of a foaming agent is added to 100 parts by weight of PVC to form an unfoamed sheet having a desired thickness. After the plain woven or knitted fabric 3 is tightly fitted with the unfoamed sheet, the unfoamed sheet is foamed at a magnification of 2 to 6 times. The foaming agent is, for example, ADCA (azodicarboxylic acid amide)
The addition amount is preferably 3 to 7 parts by weight based on 100 parts by weight of PVC. When the amount is less than 3 parts by weight, the cushioning property is poor, and when it exceeds 7 parts by weight, wrinkles are generated. The expansion ratio of the upper and lower PVC foam layers 1 and 2 is in the range of 2 to 6 times. When the expansion ratio is less than 2 times, the cushioning property is poor, and when it exceeds 6 times, wrinkles occur. Note that the expansion ratios of the upper and lower PVC foam layers 1 and 2 need not be the same and are arbitrary.

The plain woven fabric or knitted fabric 3 is a plain woven fabric made of a desired fiber in the conventional plain woven fabric (the warp yarns 3a and the weft yarns 3b alternately move up and down alternately one by one). The fibers are arbitrary, such as polyester, nylon, and woof, and the thickness and strength of warp 3a and weft 3b or the number of warp 3a and weft 3b are also arbitrary. It is not limited and can be appropriately changed. In addition, the knitted fabric is a fabric knitted by a conventionally known knitting method with a desired fiber similarly to a plain woven fabric. In the case of this knitted fabric, a cloth woven in a tubular shape is cut and used. . The material of the fiber of the plain woven or knitted fabric 3 is preferably a polyester material from the viewpoint of soap resistance. A knitted fabric is preferred when flexibility is required, and a plain woven fabric is preferred when it is required to be hardly deformed. Further, it is preferable that the plain woven fabric or the knitted fabric 3 does not shrink due to the heat at the time of foaming, or has been subjected to a heat treatment or the like in advance so as not to shrink by the heat at the time of foaming.

Accordingly, first, the plain woven fabric or the knitted fabric 3 is sandwiched between the non-foamed upper and lower PVC sheets to form an unfoamed sheet, and the end of the plain woven fabric or the knitted fabric 3 is pinned or clipped. After sandwiching and supporting, the upper and lower PVC unfoamed sheets are
By performing spatial foaming at twice the magnification, a bathroom mat A in which a plain woven fabric or a knitted fabric 3 is sandwiched between the PVC foam layers 1 and 2 is formed. The sandwiching of the unfoamed PVC sheet and the plain woven or knitted fabric 3 is performed by a so-called three-layer laminating process.

Next, a specific embodiment will be described.

The following composition was rolled with a hot roll having a surface temperature of 140 to 150 ° C. to form a pair of upper and lower unfoamed PVC sheets having a thickness of 0.5 m / m. PVC (P = 1300) 100 parts by weight DOP 60 parts by weight KF-65D-7 (Ba-Zn-based foam stabilizer) 3 parts by weight ADCA (azodicarboxylic acid amide) 5 parts by weight Calcium carbonate 10 parts by weight Antibacterial agent 0.3 Parts by weight

The plain woven fabric 3 is formed from 750 denier polyester fiber (for example, KF-7889 Kuraray Co., Ltd.) larger than the unfoamed sheet. 5m / m thick upper and lower PVC
Sandwich between unfoamed sheets and laminate three layers. Therefore, after laminating, the warp yarn 3a and the weft yarn 3b project from the boundary surface between the upper and lower PVC unfoamed sheets (not shown).

Then, each of the projecting warps 3
a, the end of an arbitrary portion or the entire end of the weft 3b is sandwiched and supported by a pin or a clip, and the plain woven fabric 3 is narrowed by the upper and lower PVC foam layers 1 and 2 by spatial foaming in a 210 ° C. heating furnace. A bathroom mat A formed by wearing was obtained.

The obtained bathroom mat A has a total thickness of 6 m.
/ M, weight 1000g / m ² , tensile strength 150kg / 3c
m (50 kg / cm ² ). Compared to the conventional mats for bathrooms having the same shape, the tensile strength of which is only about 10 kg / cm ^2, it has excellent strength while having various requirements such as barrier properties, light weight, flexibility and cushioning properties. It is obtained.

[0016]

According to the present invention, an unfoamed upper and lower PV formed by adding 3 to 7 parts by weight of a foaming agent to 100 parts by weight of PVC.
A plain woven or knitted fabric composed of desired fibers is narrowed between C sheets, and the plain or woven fabric is formed of upper and lower PVC foam layers obtained by spatially foaming the upper and lower PVC sheets at a magnification of 2 to 6 times. , The strength is greatly improved while having various requirements such as barrier properties, light weight, flexibility, cushioning properties, etc.
As a result, it was possible to provide a bathroom mat having a very high practical value which can prevent damage (such as tearing, tearing, etc.) at an early stage while maintaining ease of use.
