2. Description of the Related Art Conventionally, as a laying material having water permeability and cushioning property, there is one in which rubber of a waste tire is fixed in a chip shape to be in a mat shape. This conventional flooring material is made of rubber in a chip shape and is fixed with an adhesive, so that it has water permeability, and since rubber is easily elastically deformed, it has impact resistance and cushioning properties. For this reason, using spike shoes, etc., it is used for golf courses and clubhouses where walking feeling is poor with normal hard concrete, etc., or it has cushioning properties, it is hard to slip, and shock when falling over. Because it can be softened, it is used as a covering material for kindergartens, schools, promenades in parks, pedestrian bridges, hospitals, welfare facilities, rooftops of condominiums, jogging courses, etc.

[0003]

However, since the above-mentioned conventional laying material is mainly made of rubber, the cushioning property is excellent due to the elastic property of rubber, but the touch feeling is rubber. The first problem is that when the skin of the sole of the foot or the like comes into direct contact, the sticky feel peculiar to rubber is not very good.

Further, since the conventional flooring material is mainly made of rubber, it is easily worn and damaged.
The second problem is that it must be replaced and repaired frequently due to long-term use, which is troublesome. Further, since the rubber which is a raw material of the conventional laying material is a chip-shaped rubber of a waste tire, its original appearance color is black, which is the color of the tire, and other appearance colors are used. In order to do so, the pigment must be formed on the surface of the chip-shaped rubber, and there is a third problem that the color of the base appears due to abrasion as well as labor.

Therefore, the invention according to claim 1 is made in view of the first to third problems of the above-mentioned conventional technique, and the purpose thereof is to provide a good feeling and to walk. It is an object of the present invention to provide a covering material which is comfortable to wear, is less likely to be worn, can reduce the time for replacement and repair, does not need to be colored with a pigment, and whose appearance color does not change even when worn.

And a binder for adhering the base material (10) and the softening base material (20)
(30) mainly, the base material (10) is 40 to 70% by weight based on the total weight thereof, and the softening base material (20)
15 to 50% by weight, and the binder (30) is 10
To 10% by weight , the base material (10), softening
Until the base material (20) and binder (30) are mixed evenly
Stir and mix and mix at 150 to
Pressing into a flat plate while heating to a temperature of 190 degrees
It is characterized by being formed by .

The term "resin" means a hard resin,
Including soft resin such as vinyl chloride resin, foamed vinyl chloride resin, polyethylene resin, polypropylene resin, phenol resin, urethane resin, polyurethane resin, ABS
Resin, polystyrene resin and the like. The term "chip shape" as used herein means a crushed piece, a thin piece, a fine piece, and the like, and includes crushed powder, fine-grained powder, granulated powder, and cutting powder.

The "softening base material (20)" is mainly composed of rubber, and the "rubber" is natural rubber,
It includes any of synthetic rubbers. Here, the "natural rubber" is an amorphous substance obtained from the secretions of plants, and is a high molecular polysaccharide in which various hexoses, pentoses, methylpentoses, uronic acids and the like are bound.
For example, gum arabic and tragacanth are included. Further, “synthetic rubber” refers to a synthetic polymer substance having high elasticity and toughness like natural rubber. For example, butadiene-styrene rubber, butyl rubber, nitrile rubber, chloroprene rubber, urethane rubber, silicone rubber, fluororubber and the like are included.

Further, the "softening base material (20)" also includes chips made of waste agricultural vinyl, nitrile rubber and pigment mixed and solidified. Also,
The "binder (30)" is capable of adhering the surfaces of the base material (10) and the softened base material (20) to each other, maintains the shape of the laying material (40) so as not to fall, and has a predetermined strength. It would be nice if we could maintain. For example, a urethane adhesive or an epoxy adhesive is included.

The reason for adding the base material, soft base material and binder of the laying material according to the present invention and the reason for limiting the numerical value of the added weight% will be described below. Base Material The base material (10) is mainly in the form of a chip and is made of resin, and improves the texture and feel of the laying material (40).
In addition, since the base material (10) is mainly made of resin and is harder than the softening base material (20) which is mainly made of rubber, the covering material is
It is possible to maintain the strength of (40) and suppress the wear of the softening base material (20). Content of base material (10) is 40% by weight
When it is less than, such effects are insufficient. That is, the softening base material (20) is increased, and the texture and feel of the laying material (40) become the texture and feel of rubber, which deteriorates the texture and feel. Furthermore, the strength of the covering material (40) cannot be maintained, and the softening base material (20) is significantly worn. In addition, the base material (1
When the content of (0) exceeds 70% by weight, the litter (40) has almost no feel or feel of rubber, but the litter (40) becomes too hard as a whole, resulting in flexibility and cushioning of the product. In addition, warping due to thermal deformation after commercialization is likely to occur, and replacement and repair must be frequently performed, which is troublesome. Therefore, the content of the base material (10) is 40 to 70.
Weight%

Softening base material The softening base material (20) is mainly made of rubber in the shape of a chip, and has good cushioning properties of the covering material (40) and flexibility of the entire covering material (40). To do. That is, since the softening base material (20) is mainly made of rubber, it is more easily elastically deformed and has a lower hardness than the base material (10).
Even if a foot, a hand, a head or the like collides with 0) by shock, the shock can be absorbed by elastically deforming the softening base material (20). If the softening base material (20) is less than 15% by weight, such an effect is insufficient. That is, even if an external force is applied to the litter (40), the litter (40) does not deform,
It cannot absorb shocks and the like, resulting in poor cushioning. Further, when the softening base material (20) exceeds 50% by weight, the shock absorbing property and cushioning property commensurate with the increase in the content cannot be obtained, and the softening base material (2) commensurate with the increase in the content.
It is useless because the addition improvement of 0) cannot be obtained. Also, bedding (4
The texture and feel of the surface of (0) becomes rubber, and the texture and feel deteriorate. Therefore, the content of the softening base material (20) is 1
It is set to 5 to 50% by weight.

Binder The binder (30) adheres the surfaces of both the chip-shaped base material (10) and the chip-shaped softening base material (20) to the laying material (40).
Is added to maintain the shape and strength of the whole. If the content of the binder (30) is less than 10% by weight, such effect cannot be obtained. That is, the adhesive force is insufficient and the adhesive force is scattered, and it is difficult to commercialize the flooring material (40). Further, the content of the binder (30) is 1
When it exceeds 5% by weight, the effect of adding the binder (30) commensurate with the increase in the content cannot be improved, and it is wasteful. That is, the effect of maintaining the shape of the covering material (40) and the strength performance do not change, and the cost increases. Furthermore, base material (10)
Most of the space between the softening base material (20) and the softening base material (20) is filled, and the water permeability deteriorates. Therefore, the content of the binder 30 is 10 to 15% by weight.

Action The flooring material (40) according to the present invention is a base material mainly made of resin.
The (10) and the softening base material (20) mainly made of rubber are bonded together by a binder (30) in a chip-like state.
That is, between the base material (10), since the softening base material (20) mainly composed of rubber which is easily elastically deformed is formed, the laying material (40)
After maintaining the cushioning property and flexibility of the appropriate condition,
On the surface of the flooring material (40), the texture and feel of rubber can be suppressed, and a good texture and feel of rubber and resin can be obtained. As a result, even if the skin of the sole of the foot walks on the surface of the litter (40) with the bare feet, a good walking feeling can be obtained.

Further, since the base material (10) mainly made of resin and the softening base material (20) mainly made of rubber are formed in a chip-like state on the surface of the litter (40),
The presence of a resin that is harder than rubber makes it possible to suppress the abrasion and damage of the surface, as compared with the case where the surface of the flooring material (40) is made of only rubber. As a result, the frequency of replacement or repair due to wear or the like can be reduced, and the labor required can be reduced.

Further, in addition to rubber whose raw material color is limited to substantially the same color, since resins capable of various colors are added, by using resins of various colors, resins of different colors can be used. By changing the addition ratio of (1), it is possible to form the covering material (40) having an arbitrary appearance color without using a pigment or the like. As a result, it is not necessary to add a pigment and color it separately, and it is possible to easily apply a covering material of any color (40).
Can be obtained. In addition, since it does not use pigments, etc., there is no color loss due to long-term use, and even if some wear or damage occurs, it is possible to suppress changes in appearance color. It is possible to reduce the frequency of replacement and repair due to the change of.

The base material 10 is obtained by crushing a material consisting of a composition containing fine wood powder and a resin as a main material to obtain a chip-like material. To do. Further, since the base material 10 is mainly made of resin and is harder than the softening base material 20 mainly made of rubber, it is possible to maintain the strength of the laying material 40 and suppress the wear of the softening base material 20. is there. Specifically, the substrate 10 is
The surface of fine powder of wood flour, which is a cellulosic material, has a smaller diameter than this fine powder, and is made by carrying a powder prepared by supporting a hard surface fine powder, and crushing the resin into chips. .

The softening base material 20 is mainly in the form of a chip and is made of rubber.
It is intended to improve the flexibility and the like of the entire litter 40. That is, since the softened base material 20 is more easily elastically deformed than the base material 10 and has a small hardness, the flooring material 40 is impacted by the feet and,

Of course, as the softening base material 20, a waste tire crushed into chips may be used. Further, the above two may be mixed and used.

The binder 30 is a chip-shaped base material 10.
And the chip-shaped softening base material 20 are adhered to each other to maintain the overall shape and strength of the laying material 40. Specifically, a urethane adhesive is used. Next, a method for manufacturing the litter 40 according to the present embodiment will be described. First, a chip-shaped substrate
10 and the softening base material 20 and the binder 30 are stirred and mixed at the above-mentioned addition ratio using a mixing mill, a mixing mixer or the like. At that time, the base material 10, the softening base material 20 and the binder 30 are stirred until they are uniformly mixed without being biased.

Next, a mixture of the base material 10, the softening base material 20, and the binder 30 is uniformly mixed into a rectangular box-shaped metal mold which serves as a saucer with an upper surface open upward. It is filled and heated to a temperature of 150 to 190 ° C., and pressed from above to below in a flat plate shape with a metal material that covers the upper surface of the rectangular box shape without gaps. As the temperature rises, the binder 30 becomes the base material 10 and the softening base material 20.
Spread evenly over the surface of the. Then, the surfaces of both the base material 10 and the softening base material 20 are brought close to each other by pressing and strongly pressed against each other, the base material 10 and the softening base material 20 are firmly bonded via the binder 30, and the whole is It is possible to obtain a flat product by integrating them. As a result, the laying material 40 in which the chip-shaped base material 10 and the softening base material 20 are adhesively fixed by the binder 30 while having a mesh-like gap is completed.

Next, the operation and effect of the above-described embodiment will be described. In the laying material 40 according to the present embodiment, a base material 10 mainly made of resin and a softening base material 20 mainly made of rubber are bonded by a binder 30 in a chip-like state. That is, since the softening base material 20 mainly composed of rubber that is easily elastically deformed is formed between the base materials 10, the cushioning property and the flexibility of the covering material 40 are maintained in an appropriate state, and then the covering material 40 is spread. On the surface of the material 40, the texture and feel of rubber can be suppressed, and a good texture and feel can be obtained. That is, specifically, since the base material 10 is formed of a composition having fine particles of wood powder and a resin as a main material, it is possible to obtain the texture and feel of wood on the surface of the flooring material 40. . As a result, when walking on the litter 40 with bare feet, it is possible to obtain a good feel of wood from the skin of the soles of the feet while providing appropriate cushioning properties due to the softening base material 20. It is possible to make the walking feeling with bare feet comfortable. Also, with respect to the appearance of the surface of the litter 40, the slippery feel of the surface peculiar to the resin is suppressed, and it is possible to obtain the good texture peculiar to the tree, which is soft and soft that the tree has.

That is, by selecting and using, as the surface fine powder, those having various characteristics such as electrical characteristics, chemical characteristics, or heat resistance, various types can be obtained with respect to the base material 10 made of a chip-shaped resin which is the molded product. Properties can be imparted and, as a result, the properties of the litter 40, including its substrate 10, can be varied. Specifically, when an inorganic pigment is used as the surface fine powder, the heat resistance is improved, so compared to the case of simply mixing wood powder with a resin, the heat influence at the time of molding is less, and therefore the color and shape are improved. It is possible to form a resin in which deterioration of the resin is suppressed. As a result, it is possible to form the laying material 40 using the base material 10 made of this resin, in which alteration such as change in color or shape is suppressed. As described above, by using the surface fine powder having different physical properties, it is possible to obtain the laying material 40 having different characteristics such as electrical characteristics, chemical characteristics, and heat resistance.

Further, since the base material 10 mainly made of resin and the softening base material 20 mainly made of rubber are formed in a chip-like state on the surface of the spread material 40, the spread material 40
Since the surface of 40 is made of a resin harder than rubber than that made of only rubber, abrasion and damage of the surface can be suppressed. As a result, the frequency of replacement or repair due to wear or the like can be reduced, and the labor required can be reduced.

Further, in addition to the rubber whose raw material color is limited to substantially the same color, since resins capable of various colors are added, it is possible to use resins of various colors and to use resins of different colors. By changing the addition ratio of, it is possible to form the laying material 40 having an arbitrary appearance color without using a pigment or the like. As a result, it is not necessary to separately add a pigment for coloring, and it is possible to easily obtain the litter 40 of any color. Also, because no pigments are used,
There is no color loss due to long-term use, and it is possible to suppress changes in appearance color even if some wear or damage occurs, and the frequency of replacement and repair due to changes in appearance color Can be reduced.

Next, a second embodiment will be described. The present embodiment is characterized in that the base material 10 is formed of artificial marble obtained by curing a liquid resin. The operation and effect of this embodiment will be described.

In addition, in Comparative Example 14 in which the amount of the base material 10 added was large, the entire laying material 40 became too hard, and the cushioning property and flexibility deteriorated. Further, warpage due to thermal deformability after commercialization occurred, and the thermal deformability deteriorated. Further, in Comparative Example 15 in which the addition amount of the softening base material 20 was small, the cushioning property, the flexibility and the heat deformability were deteriorated as in Comparative Example 14. Comparative Example 1 in which the softening base material 20 is added in a large amount
Similar to Comparative Example 13, No. 6 had a rubbery texture and feel, and the texture, feel and strength were deteriorated. Further, in Comparative Example 17 in which the heating temperature was low, the binder 30 was not uniformly distributed, the adhesive strength was weakened, some parts were scattered in the product, and the strength was also poor. In addition, in Comparative Example 18 in which the heating temperature is high, an effect commensurate with the increase in the heating temperature is not obtained, and further, a part of the resin is deformed and melted by heat, and
The gap between 10 and the softening base material 20 was filled, resulting in poor water permeability.
