Description

Elastic absorbent floor mat

Technical field

This application is related to the absorbent floor mat at the entrance of the bathroom, and more specifically refers to an elastic absorbent mat.

Background technique

In the early days, water-absorbing mats at the entrance of the bathroom were mostly woven fabrics, which mainly used capillary phenomena to absorb water, but they had no anti-slip effect, and they were prone to slipping when stepped on. In order to solve these shortcomings, the industry has developed a woven fabric and rubber bonded absorbent floor mat, which can absorb water by the woven fabric on the top side and the rubber bottom layer on the bottom side to prevent slippage, which has both appropriate water absorption and anti-slip effects.

Although the aforementioned absorbent floor mats with a rubber bottom layer are more effective than traditional woven fabrics, the time for ordinary people to step on the absorbent mats is usually not long. In a short contact time, it is difficult for woven fabrics to use the capillary phenomenon to quickly remove the soles of the feet or shoe soles. After the moisture has been absorbed, it often happens that the soles of the feet or shoe soles carry residual moisture into the indoor floor.

Secondly, in recent years, the common hard diatomite absorbent mats are mainly made of mixed water of gypsum and diatomite powder. The porous material characteristics can quickly absorb water, and the water absorption rate is faster than that of woven cloth. However, its There are problems such as poor pedaling feel, easy to break and easy to slip (need to be used with anti-slip pads). Obviously, there are also areas for improvement.

To this end, the applicant has developed the Chinese utility model No. ZL201921062530.3 patent, the Chinese Taiwan Invention No. I693909 and the Chinese Taiwan New No. M582806 "Elastic Water Absorbent Mat" patents, which are made of connected porous foam. It is composed of an anti-slip layer and an elastic layer, and the surface of the elastic layer is further provided with multiple broken areas that are generally broken and rough. The foam material of the elastic layer is further mixed with water-absorbing materials, which can use the elastic layer It quickly absorbs water from the soles of the feet or soles, and has a soft pedaling feel and does not slip. Therefore, it can indeed solve the shortcomings of the existing rubber-based absorbent floor mats and hard diatomite absorbent floor mats.

However, the elastic water-absorbent mat is made of porous foam after all, and its appearance is less beautiful. Therefore, the surface of the elastic layer must be attached with a cloth layer, and the cloth layer needs to be dyed and printed with patterns, which is more attractive to consumers Buy and use. However, the printed ink easily blocks moisture from being absorbed by the cloth layer (the time for absorbing 1 ml of water is extended from 30 seconds to about 60 seconds), but it reduces the water absorption speed of the elastic absorbent mat. So far, there is no solution in the technical field. The technology of ink delaying the absorption rate of water is very difficult.

detailed description

The application will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the application, but the examples cited are not intended to limit the application.

Please refer to FIGS. 1 and 2, an elastic water-absorbing floor mat 10 according to a preferred embodiment of the present application, which can be placed at the door of a bathroom, includes an elastic layer 12 and a textile layer 14.

The elastic layer 12 is a porous foam made of a foam material with a water-absorbing effect, such as natural rubber (NR), synthetic rubber (PU), polyurethane (PVC) or styrene butadiene rubber ( SBR) and other foamed materials, this embodiment is synthetic rubber, the foamed material is added with 5% to 85% of water-absorbing material (the higher the ratio, the softness of the elastic layer 14 gradually decreases), the water-absorbing material refers to the existing There are mineral powders such as diatomite, pottery clay, clay, and sand, or/and plant powders such as cotton and cold weather, or/and chemical powders such as silt, slag, super absorbent resin, nylon, and polyacrylate. A non-slip part 22 with a concave-convex structure.

The textile layer 14 is a porous cloth such as a non-woven fabric or a sandwich mesh. The elastic layer 12 is foamed with the force generated and the foaming agent contained in the raw material is chemically changed. Glue is attached to the top side of the elastic layer 12, and its surface is also printed with a number of printing areas 24 with ink. Each of the printing areas 24 occupies between 5% and 100% of the surface area of the textile layer 14, and the printed ink is still Mixed with 5% to 95% water absorbing material, the water absorbing material refers to the existing diatomaceous earth powder, pottery clay, clay, sand and other mineral powder or/and cotton, cold weather and other plant powder or/and sludge, slag, high water absorption Chemical powders such as resin, nylon, polyacrylate, etc.

In this way, the elastic water-absorbent mat 10 of the present application is made of porous foamed elastomer and has a number of printed areas 24 on the surface of the textile layer 14, which can be stepped on when the bather walks out of the bathroom, and the stepping feeling is very soft And the surface of the textile layer 14 is provided with a plurality of printing areas 24. Because the ink of each printing area 24 contains water-absorbing material, each of the printing areas 24 can quickly absorb the moisture of the sole or sole of the foot, and then pass the textile The layer 14 absorbs moisture and introduces it into the elastic layer 12, as shown in FIG. 2. The three-dimensional, loose fabric structure of the textile layer 14 can not only absorb water, conduct water and drain to the elastic layer 12, but also help to dry the absorbed moisture. , And through the anti-slip property of the bottom side anti-slip part 22 of the elastic layer 12 with respect to the ground, the elastic water-absorbent mat 10 will not slide on the ground when stepped on, so as to avoid the occurrence of sprained or slipped feet.

Although the existing porous foam mats (such as yoga mats) made of foam materials have the effect of absorbing water, the water absorption speed is very slow. In actual tests, when water drops on the printed area 24 on the surface of the textile layer 14, it only takes less than 1 second to absorb 1 ml of water, that is, the water absorption speed is about 15-30 times that of the existing porous foam pad. , Each of the printing areas 24 can indeed improve the water absorption effect of the textile layer 14.

In addition, the higher the proportion of each printing area 24 to the entire surface area of the textile layer 14, the higher the probability of contacting each printing area 24 when shoes or feet are stepped on the elastic water-absorbent mat 10 can ensure that shoes or feet The water of the sole is completely and quickly absorbed. Of course, if the proportion of each printing area 24 to the overall surface area of the textile layer 14 is low, it can be arranged in the middle part of the top side of the textile layer 14, which is more susceptible to being stepped on by shoes or feet.

Secondly, through actual tests, when the proportion of the ink and the elastic layer 12 added to the water absorbing material in each printing area 24 is 5%, the water absorbing time can be shortened by about 15% to 20%, and the proportion of adding water absorbing material to the elastic layer 12 is increased. When it reaches 25% (the proportion of water-absorbing material added to each printing area 24 remains unchanged), the water absorption time can be shortened by about 35% to 40%, that is, if each printing area 24 absorbs 1 ml of water, it takes 1 second (addition 5% water-absorbing material), and when the elastic layer 1 is also added with 5% water-absorbing material, the water absorption time of 0.15-0.2 seconds can be shortened in total, that is, the water absorption time only needs 0.8 to 0.85 seconds, and when the elastic layer 14 is added When there is 25% water absorbing material (the proportion of water absorbing material added to each printing area 24 remains unchanged, it is still 5%), the water absorption time can be shortened by 0.35-0.4 seconds, that is, the water absorption time is only 0.6 to 0.65 seconds, that is When the proportion of water-absorbing material added to the elastic layer 12 is gradually increased, the water absorption time will gradually be shortened. Of course, as the proportion of water-absorbing material added to the elastic layer 12 increases, its flexibility will gradually decrease, in order to avoid the complete loss of the elastic layer 12 Elasticity, the maximum proportion of water-absorbing material added to the elastic layer 12 in this application is 85%.

In other words, when the proportions of the ink in each printing area 24 and the water-absorbing material added to the elastic layer 12 are higher, the water-absorbing speed of the elastic water-absorbing mat 10 will increase rapidly.

Furthermore, the anti-slip portion 22 on the bottom side of the elastic layer 12 can not only produce anti-slip properties relative to the ground, but also can create a plurality of gaps on the bottom side of the elastic layer 12 for air circulation, and enhance the elastic water-absorbent mat 10 The effect of air drying on the bottom side.

Next, as shown in FIG. 3, the elastic water-absorbent floor mat 30 of another preferred embodiment of this application has substantially the same composition as the elastic water-absorbent floor mat 10, except that the ink in each printing area 32 penetrates into the textile The layer 34, that is, the part of the bottom of each printing area 32 also extends into the interior of the textile layer 34. These structures can increase the contact area between each printing area 32 and the textile layer 34, thereby increasing the separation of the textile layer 34 The speed at which moisture absorbed by the printing area 32 is introduced into the elastic layer 36. As for how much ink in each printing area 32 penetrates into the textile layer 34, the amount of ink and the degree of weaving density of the textile layer 34 can be controlled.

As shown in FIG. 4, the elastic water-absorbent mat 40 of another preferred embodiment of this application is different from the elastic water-absorbent mat 30 in that the ink in each printing area 42 not only penetrates into the textile layer 44 but also connects to the elastic layer 46. Therefore, compared with the elastic water-absorbent mat 30, the elastic water-absorbent mat 40 is also connected to the elastic layer 46 through each printing area 42, so that the water absorbed by each printing area 42 can pass through two ways (textile layer). The conductive and printed area 42 of 44 is directly transferred to the elastic layer 46) and transported to the elastic layer 46, and the water absorption speed can be faster than that of the elastic water-absorbing mat 30. To make the ink of each printing area 42 penetrate into the textile layer 34 and connect to the elastic layer 46, it can be obtained by increasing the amount of ink or controlling the density of weaving of the textile layer 34.

It can be seen from the above that the elastic water-absorbent mat provided by the present application, which is composed of several printed areas on the surface of the elastic layer and the textile layer, not only absorbs water quickly, but also has a soft stepping feeling and does not slip, which can solve the problem of traditional woven fabric floor mats. The shortcomings of poor water absorption and easy slippage, as well as the common hard diatomite absorbent mats in recent years are easy to break, easy to slip and have poor touch. It can also solve the problem that the ink will easily block water and be absorbed when the cloth surface is printed. The question is of great practical value.

The above-mentioned embodiments are only preferred embodiments for fully explaining the present application, and the protection scope of the present application is not limited thereto. The equivalent substitutions or transformations made by those skilled in the art on the basis of this application are all within the protection scope of this application. The scope of protection of this application is subject to the claims.
