[0008]

SUMMARY OF THE INVENTION The present invention is to achieve the above object. The invention according to claim 1 is
Chip-shaped base material mainly made of resin (10), chip-shaped softened base material mainly made of rubber (20), and binder (30) for bonding base material (10) and softened base material (20) And the substrate (10) has a weight of 4 based on their total weight.
0 to 70% by weight, the softened base material (20) is 15 to 50%
% By weight, and the binder (30) is 10 to 15% by weight.
In the range.

Here, “resin” is a hard resin,
Including soft resin, for example, vinyl chloride resin, foamed vinyl chloride resin, polyethylene resin, polypropylene resin, phenol resin, urethane resin, polyurethane resin, ABS
Resin, polystyrene resin and the like. Here, the term “chip shape” means crushed pieces, thin pieces, fine pieces and the like, and includes pulverized powder, fine powder, granulated powder, and cutting powder.

[0010] The "softening substrate (20)" is mainly composed of rubber, and the "rubber" is a natural rubber,
It includes any of synthetic rubbers. Here, “natural rubber” is an amorphous substance obtained from secretions of plants, and is a high molecular polysaccharide to which various hexoses, pentoses, methyl pentoses, uronic acids and the like are bound.
For example, gum arabic, gum tragacanth, and the like are included. The term "synthetic rubber" refers to a synthetic polymer substance exhibiting high elasticity and toughness like natural rubber. For example, butadiene-styrene rubber, butyl rubber, nitrile rubber, chloroprene rubber, urethane rubber, silicone rubber, fluorine rubber and the like are included.

The "softening base material (20)" also includes a chip made from a solidified mixture of waste agricultural vinyl, nitrile rubber and pigment. Also,
The `` binder (30) '' can adhere the surfaces of the base material (10) and the softened base material (20) to each other, maintain the shape so as not to disperse as the laying material (40), and maintain a predetermined strength. It is good if it can be maintained. For example, it includes a urethane-based adhesive or an epoxy-based adhesive.

Hereinafter, the reason for adding the base material, the soft base material and the binder of the litter according to the present invention and the reason for limiting the numerical value of the added weight% will be described. Substrate The substrate (10) is mainly made of resin in the form of a chip, and improves the texture and feel of the laying material (40).
The base material (10) is mainly made of resin, and is harder than the softened base material (20) mainly made of rubber.
The strength of (40) can be maintained, and the wear of the softened base material (20) can be suppressed. The content of the base material (10) is 40% by weight.
If it is less than this, such an effect is insufficient. That is, the amount of the softened base material (20) increases, and the texture and feel of the laying material (40) becomes the texture and feel of the rubber, thereby deteriorating the texture and feel. Further, the strength of the laying material (40) cannot be maintained, and the softened base material (20) is significantly worn. The base material (1
When the content of (0) exceeds 70% by weight, the feel and texture of rubber are almost eliminated in the litter (40), but the litter (40) becomes too hard, and the flexibility and cushioning properties of the product are increased. In addition, warpage due to thermal deformation after commercialization is apt to occur, and replacement and repair must be frequently performed, which is troublesome. Therefore, the content of the substrate (10) is 40 to 70
% By weight.

Softening base material The softening base material (20) is mainly made of rubber in the form of chips and has good cushioning properties of the laying material (40) and good flexibility of the laying material (40) as a whole. Is what you do. That is, the softened base material (20) is mainly made of rubber, and is easily elastically deformed and has a lower hardness than the base material (10).
Even if the foot, hand, head or the like collides with 0) by impact, the softened base material (20) can absorb the impact by elastically deforming. When the softened 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) is not deformed,
Cushioning properties are impaired because impacts and the like cannot be absorbed. On the other hand, when the softening base material (20) exceeds 50% by weight, it is not possible to obtain shock absorption and cushioning properties corresponding to the increase in the content, and the softening base material (2
The improvement in the addition of 0) cannot be obtained, and this is wasteful. Also, bedding materials (4
The texture and feel of the surface of (0) becomes rubber, and the texture and feel deteriorate. Therefore, the content of the softened substrate (20) is 1
5 to 50% by weight.

Binder The binder (30) is used for bonding the surfaces of both the chip-shaped base material (10) and the chip-shaped softened base material (20) to form a laying material (40).
Is added in order to maintain the shape and strength as a whole. When the content of the binder (30) is less than 10% by weight, such an effect cannot be obtained. That is, the adhesive strength is insufficient and the adhesive is separated, which makes it difficult to commercialize the laying material (40). When the content of the binder (30) is 1
If the content exceeds 5% by weight, the effect of adding the binder (30) corresponding to the increase in the content cannot be improved, and it is useless. That is, the effect of maintaining the shape as the laying material (40) and the strength performance are not changed, and the cost is increased. Furthermore, the base material (10)
Almost completely fills the gap between the substrate and the softened base material (20), resulting in poor water permeability. For this reason, the content of the binder (30) is set to 10 to 15% by weight.

The litter (40) according to the present invention is a base material mainly composed of resin.
(10) and a softened base material (20) mainly made of rubber are bonded by a binder (30) in a chip-like state.
That is, since a softened base material (20) mainly composed of rubber that is easily elastically deformed is formed between the base materials (10), the laying material (40)
After maintaining the cushioning and flexibility of the moderate state,
On the surface of the laying material (40), the texture and feel of the rubber are suppressed, and a good texture and feel of the rubber and the resin can be obtained. Accordingly, even when the surface of the litter (40) is walked with bare feet and the skin of the sole directly contacts the surface of the litter (40), a good walking feeling can be obtained.

Further, on the surface of the laying material (40), a substrate (10) mainly composed of resin and a softened substrate (20) mainly composed of rubber are formed in a chip-like state.
The surface of the laying material (40) can suppress abrasion and abrasion of the surface due to the presence of the resin harder than the rubber, compared to the case where the surface is made of only the rubber. As a result, the frequency of replacement or repair due to wear or the like can be reduced, and such labor can be reduced.

Further, since resins capable of various colors are added in addition to rubber whose raw material colors are limited to substantially the same color, the use of resins of various colors makes it possible to use resins of different colors. By changing the rate of addition, a litter (40) having an arbitrary appearance color can be formed without using a pigment or the like. As a result, there is no need to separately add a pigment for coloring, and it is easy to use
Can be obtained. In addition, since pigments and the like are not used, there is no discoloration due to long-term use, and furthermore, even if abrasion or wear occurs partially, it is possible to suppress a change in appearance color, The frequency of replacement or repair due to the change in the number can be reduced.

The second aspect of the present invention is the first aspect of the present invention.
In addition to the features described above, the base material (10) is characterized by being formed from a composition mainly composed of wood powder and resin. Here, the term "fine particle wood powder" includes not only natural wood but also fine wood-like particles obtained by pulverizing wood offcuts, sawdust and the like that are generated when building a house or the like.

According to the present invention, the base material (10) comprises fine particle wood powder,
It is formed from a composition mainly composed of a resin. For this reason, the texture and feel of wood can be obtained on the surface of the laying material (40). Thus, when walking on the laying material (40) with bare feet, the soft base material (20) has a moderate cushioning property, and the skin on the sole of the foot gives a good feel to the tree. And a comfortable walking feeling with bare feet can be obtained. In addition, as for the appearance of the surface of the laying material (40), the smooth feel of the surface peculiar to the resin is suppressed, and the good texture peculiar to the wood which is soft and soft and has the fall of the tree can be obtained. In addition, when the laying material (40) is laid in a room or on a roof or the like using a wooden material as a surface member, or a material having a woody texture, it is suitable for use in a sense of harmonizing the external design. .

Specifically, it refers to fine powder of titanium oxide, ferrite, aluminum, nickel, silver, ceramic, calcium carbonate, and the like.

The base material (10) is formed by extrusion molding of a resin obtained by mixing a powder prepared by supporting a fine powder having a smaller diameter and a hard surface than the fine powder on the surface of the fine powder of the cellulosic material. After the product formed as a resin product was used as a product by injection molding or the like, the recovered product was crushed into chips, or was formed as a scrap material or defective product generated in the above-described product manufacturing process. This includes those obtained by finely pulverizing things or the like into chips.

In the present invention, a resin is formed by mixing a powder prepared by supporting a fine surface powder having a smaller diameter and a hard surface than the fine powder on the surface of the fine powder of the cellulosic material.
For this reason, the properties or functions of the resin of the final molded article are determined only by the properties and functions of both the fine powder of the cellulosic material and the resin, while the properties of the molded article are determined by the properties of the surface fine powder. It can be changed by selection. That is, as the surface fine powder, by selectively using those having various properties such as electrical properties, chemical properties, or heat resistance, the base material (10) made of a chip-shaped resin as a molded product thereof Thus, various characteristics can be imparted, and as a result, the characteristics of the laying material (40) including the base material (10) can be changed.

The invention according to claim 4 is the above-described claim 1.
In addition to the features described, the base material (10) is formed of artificial marble obtained by curing a liquid resin. Here, the “artificial marble obtained by curing a liquid resin” is formed by injecting a liquid resin into a molding cell and curing the resin, and the subtle color, depth, texture, and luxury of natural marble It has an appearance close to. And, here, the "liquid resin" is usually a mixture, and the composition thereof is not particularly limited.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described in more detail with reference to the drawings. 1 and 2
FIG. 1 shows a first embodiment of the present invention.
Is a partially enlarged schematic view of the laying material, and FIG. 2 is an external perspective view of the laying material. First, the configuration of the present embodiment will be described.

The litter 40 according to the present embodiment includes a chip-shaped base material 10 mainly made of resin, a chip-shaped softened base material 20 mainly made of rubber, a base material 10 and a softened base material 20.
And a binder 30 for adhering the adhesive. The litter 40 is 40 to 70% by weight based on the total weight thereof, and the softened substrate
20 is 15 to 50% by weight, and the binder 30 is 10% by weight.
-15% by weight.

The base material 10 is obtained by pulverizing a composition composed mainly of fine-grained wood powder and a resin into chips to improve the texture and feel of the laying material 40. Is what you do. Further, since the base material 10 is mainly made of resin and is harder than the softened base material 20 mainly made of rubber, the strength of the spreading material 40 can be maintained and the wear of the softened base material 20 can be suppressed. is there. Specifically, the base material 10 is
A resin obtained by mixing a powder prepared by supporting a fine powder having a smaller diameter than the fine powder on the surface of the fine powder of the wood powder, which is a cellulosic material, is crushed into chips. .

The softened substrate 20 is mainly made of rubber in the form of a chip, and has a cushioning property of the laying material 40,
This is to improve the flexibility and the like of the entire laying material 40. That is, since the softened base material 20 is more easily elastically deformed than the base material 10 and has a lower hardness, the foot 40 or the like is impacted on the laying material 40,
Even if a hand, a head, or the like collides, the softened base material 20 is elastically deformed so that the shock can be absorbed and the shock resistance and the cushioning property are improved. More specifically, waste agricultural vinyl, nitrile rubber, and pigment are melted and integrally mixed and pulverized into chips for use. Needless to say, the softened base material 20 may be one obtained by pulverizing a waste tire into chips. Further, the above two may be mixed and used.

The binder 30 is made of a chip-shaped base material 10.
The surface is bonded to the chip-shaped softened base material 20 and added to maintain the overall shape and strength of the laying material 40. Specifically, a urethane-based 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 softened base material 20 and the binder 30 are stirred and mixed at the above-described addition ratio using a mixing mill or a mixing mixer. At this time, the stirring is performed until the base material 10, the softened base material 20, and the binder 30 are uniformly mixed without unevenness.

Next, a mixture of the base material 10, the softened base material 20 and the binder 30 is uniformly mixed into a metal mold which is a square box and has a top surface opening upward. While filling and heating to a temperature of 150 to 190 ° C., it is pressed in a flat plate shape from a metal so as to cover the upper surface of the square box from above without any gap. As the temperature rises, the binder 30 becomes the base material 10 and the softened base material 20.
And spread uniformly over the surface of the. Then, when the surfaces of both the base material 10 and the softened base material 20 are close to each other by pressing and strongly pressed together, the base material 10 and the softened base material 20 are firmly adhered to each other via the binder 30, and the whole is Together, a flat product can be obtained. As a result, the laying material 40 in which the chip-shaped base material 10 and the softened base material 20 are adhered and fixed by the binder 30 while having a mesh-like gap is completed.

Next, the operation and effect of the above embodiment will be described. In the laying material 40 according to the present embodiment, the base material 10 mainly made of resin and the softened base material 20 mainly made of rubber are bonded with the binder 30 in a chip-like state. That is, since the softened base material 20 mainly composed of rubber which is easily elastically deformed is formed between the base materials 10, the cushioning property and flexibility of the spreading material 40 are maintained in an appropriate state, On the surface of the material 40, the texture and feel of the rubber can be suppressed, and a good texture and feel can be obtained. That is, specifically, since the base material 10 is formed from a composition mainly composed of wood powder of fine particles and a resin, the texture and feel of wood can be obtained on the surface of the laying material 40. . Thereby, when walking on the laying material 40 with bare feet, in addition to having a moderate cushioning property by the softened base material 20, a good feeling of a tree can be obtained from the skin of the sole of the foot. It is possible to make the walking feeling with bare feet comfortable. In addition, with regard to the appearance of the surface of the laying material 40, the smooth feel of the surface peculiar to the resin is suppressed, and the good texture peculiar to the wood which is soft and soft and falls down can be obtained. In addition, when the laying material 40 is laid on a room or a roof where a wooden material or a material having a woody texture is used as the surface member, the laying material 40 is suitable for use in terms of harmonizing the external design.

Further, in the present embodiment, a resin is formed by mixing a powder prepared by carrying a hard surface fine powder having a smaller diameter than the fine powder on the surface of the fine powder of the cellulosic material. I have. For this reason, the properties or functions of the resin of the final molded article are determined only by the properties and functions of both the fine powder of the cellulosic material and the resin, while the properties of the molded article are determined by the properties of the surface fine powder. Can be changed by selection. That is, by selectively using, as the surface fine powder, those having various characteristics such as electric characteristics, chemical characteristics, or heat resistance, various types of the base material 10 made of a chip-shaped resin, which is a molded product thereof, are obtained. Properties can be provided, and as a result, the properties of the litter 40 including the substrate 10 can be changed. Specifically, when an inorganic pigment is used as the surface fine powder, the heat resistance is improved. Therefore, compared to a case where wood powder is simply blended with a resin, the heat effect at the time of molding is small, and thus the color and shape are reduced. This can form a resin in which alteration such as a change in the quality is suppressed. Accordingly, it is possible to form a laying material 40 using the base material 10 made of this resin, in which deterioration such as a change in color or shape of the laying material 40 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 various characteristics such as electric characteristics, chemical characteristics, and heat resistance.

Further, since the base material 10 mainly made of resin and the softened base material 20 mainly made of rubber are formed in a chip-like state on the surface of the spreading material 40,
Due to the presence of the resin whose surface is harder than that of the rubber whose surface is made of only rubber, wear and tear 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 such labor can be reduced.

Further, since resins capable of various colors are added to the rubber whose raw material colors are limited to substantially the same color, the use of resins of various colors makes it possible to use resins of different colors. By changing the addition ratio of, the litter 40 having an arbitrary appearance color can be formed without using a pigment or the like. Accordingly, it is not necessary to separately add a pigment to perform coloring, and it is possible to easily obtain the laying material 40 having an arbitrary color. Also, because no pigments are used,
Long-term use does not cause discoloration, and even if parts are worn or worn, the appearance color can be prevented from changing, and the frequency of replacement or repair due to the change 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 from artificial marble obtained by curing a liquid resin. The operation and effect of the present embodiment will be described.
In the present embodiment, since the artificial marble is used for the base material 10, the feel and texture of the surface of the laying material 40 can be made to be a marble feel, and the laying material 40 can have a sense of quality. . And, since the chip-shaped litter 40 and the softened base material 20 are adhered to each other, when walking on the surface of the litter 40 with bare feet, the skin on the back surface of the foot may have a marble feel. In addition, the cushioning property of the softened base material 20 is obtained, and a comfortable walking feeling can be obtained. Further, since both are formed in a chip shape and adhered to form the laying material 40, a mesh-like gap is formed between them, and the laying material 40 having excellent water permeability is obtained. be able to. Further, even if the surface of the base material 10 made of artificial marble is wet and slippery, the softened base material 20 mainly made of rubber is arranged between the base materials 10 to obtain a large frictional resistance. Can be prevented and slipping can be suppressed.
Further, since the base material 10 and the softened base material 20 having different hardnesses are bonded in a chip shape, minute irregularities can be formed on the surface thereof, and a large frictional resistance can be obtained. , Can be prevented from slipping.

In Comparative Example 12 in which the amount of the binder 30 added was large, the gap between the base material 10 and the softened base material 20 was filled, and the water permeability was poor. In Comparative Example 13 in which the amount of the base material 10 added was small, the texture and feel were rubber, and the texture and feel were poor. In addition, the strength was also reduced to be poor. In Comparative Example 14 in which the amount of the base material 10 added was large, the entirety of the laying material 40 was too hard, and the cushioning property and flexibility were poor. In addition, warpage due to thermal deformability after commercialization occurred, resulting in poor thermal deformability. In Comparative Example 15 in which the amount of the softened base material 20 added was small, the cushioning property, flexibility, and heat deformability were poor as in Comparative Example 14. Comparative Example 1 in which the amount of the softened base material 20 was large.
As for Comparative Example 6, similarly to Comparative Example 13, the texture and feel were those of rubber, and the texture, feel and strength were reduced. In Comparative Example 17 in which the heating temperature was low, the binder 30 was not uniformly distributed, the adhesive strength was weak, a part of the product was dispersed, and the strength was poor. In Comparative Example 18 in which the heating temperature was high, the effect corresponding to the increase in the heating temperature was not obtained. Further, deformation and melting due to heat occurred in a part of the resin,
The gap between 10 and the softened base material 20 was filled, resulting in poor water permeability.
