る衝撃吸収床材に関復る。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a single-type or directly-attached five-type wood-based shock-absorbing flooring material. It is suitable for use on floors above floors in apartment complexes, and is used to reduce the impact noise of floors, such as the sounds of moving tables, chairs, etc., or the sounds of people walking, especially the sounds generated when walking while wearing hard slippers. This article focuses on shock-absorbing flooring materials that can provide a comfortable living environment by blocking these sounds and preventing them from propagating downstairs.

殆ど発生しなくなった。[If conventional technology 1] Impact noise that is transmitted from the upper floor to the lower floor through the concrete slab in a concrete apartment complex is caused by the sound generated when moving tables and chairs, and the sound generated when tableware such as spoons is dropped. Lightweight floor caused by falling hard objects such as! Impact noise can be broadly divided into i-striking height and heavy floor impact noise, which is generated when a soft heavy object falls, such as the sound that occurs when a child jumps. Of these, heavy floor impact noise can be solved by increasing the rigidity of the concrete floor slab by increasing the thickness of the concrete slab or increasing the number of beams.
In recent years, the slab thickness, which used to be 20 to 130 m, has been standardized to 150 m or more, so complaints due to heavy floor impact noise have almost no longer occurred.

望まれるようになってきた。On the other hand, it is believed that it is effective to use soft upholstery on the floor surface to absorb light floor impact sound, and for this reason, in Japan's current apartment complexes, the method of laying carpets, etc. on the floor surface is widely used. However, in recent years, asthma caused by dust mites in carpets has become a serious problem, and flooring materials that can replace carpets have become desirable.

木質系床材の開発が望まれている。On the other hand, wood-based flooring materials have the advantages of being free from dust mites, easy to clean, easy to remove dust, etc., and being like a needle bed. Furthermore, wood-based flooring is a great substitute for the coldness of steel and concrete buildings, and the beauty of the wood's color tone and grain gives a psychological sense of peace, and its heat-retaining and heat-insulating effects make it popular among naturalists and wood grains. In recent years, not only has iJB been used as a flooring material in newly constructed properties, but RiffA-
There is also a growing need for re-adhesive materials to be used during maintenance. However, wood flooring has poor sound insulation properties (particularly for lightweight floor impact noise), and especially in apartment complexes, there is a problem in that the sound from the rooms on the upper floor is easily transmitted to the rooms on the lower floor. There have been many complaints due to the above noise, and there is a desire for the development of a superior wood flooring material with high sound insulation properties.

Measures have been taken to absorb shocks from above the floor (lightweight method shocks) by increasing the thickness of the floorboards to 150 to 200m, and by placing low (soft) rubber or urethane cushioning materials with a low spring constant on some of the floorboards. has been done.

There are problems such as the living space feeling psychologically small due to the There is also the problem that the cost of materials increases as the thickness of the flooring (board) increases, resulting in higher costs. In addition, the method of installing a soft rubber or urethane cushion layer under the flooring uses a cushioning material with a low spring constant (fluffy), which makes the walking sensation soft and uncomfortable, or creates a feeling of discomfort when walking on furniture. It is dangerous because the stability of
For example, when the furniture is a cupboard, there are problems such as when a person walks by the cupboard, the cupboard shakes and the dishes make noise.

がある。In addition, those with an elastic layer of a fiber resin composite made of a fiber resin made of soft resin and fibers and a plywood layer between the wood surface material and the uneven body have improved shock absorption ability, rigidity and stability. However, when a thermosetting resin is used as the soft resin, it is necessary to perform a thermosetting process when manufacturing the laminate, making the work complicated and requiring a long manufacturing time per sheet, which reduces productivity. It will be inferior to In addition, even when only thermoplastic resin is used, the manufacturing process can be carried out using only a heat bonding process and is simple, but if the matrix strength of the resin composite is low and the strength of the wood surface material or plywood is low. However, there is a problem in that the strength of the entire laminate decreases.

きい程衝撃吸収性能が高くなる。The first characteristic required of such impact-absorbing flooring materials is impact-absorbing performance. This is because the impact applied to the wood flooring material is generally transmitted to the resin composite as solid propagation, and the resin composite converts this vibration into thermal energy through internal loss and absorbs it. Much depends on the nature of the Therefore, as for the resin composite, the larger the loss tangent (tan δ) as m representing the internal loss, the higher the impact absorption performance.

いては樹脂複合体の構成要素として繊維ネットを用いる
ことを骨子の一つとするところである。In this case, since the matrix strength is insufficient with only thermoplastic resin, fillers, short fiber fillers, fibrous nonwoven fabrics, etc. have already been blended in order to improve this strength. However, when using thin wood-based surface materials or plywood for flooring, or when making slits in the surface material of moeki materials to improve shock absorption performance, the filler applied earlier may be used. Even if such components are blended, it is difficult to maintain the matrix strength to a level that can withstand practical use. For the above reasons, one of the main points of the present invention is to use a fiber net as a component of the resin composite.

Synthetic fiber nets such as tyrene, polyvinyl pyrene, polyvinyl chloride, polyester or nylon, inorganic fiber nets such as glass and carbon fiber, and metal fiber nets such as iron, aluminum, stainless steel, and copper are listed. It will be done. Among these, synthetic fiber nets are particularly preferred from the viewpoint of ease of handling and price of the flooring material. In addition, regarding the fiber density and fiber #Il diameter of such a fiber net, 19 of the resin composites,
There are 10 types that can be selected depending on the strength, but the density of fiber 1 is preferably 10 mesh or more based on the strength of the resin composite, and the fiber diameter is based on the adhesive strength between the resin composite and the wood surface material or plywood. It is preferable that the thickness is greater than or equal to the thickness of the resin composite. Furthermore, such a fiber net is not limited to the use of only one piece as in the embodiment shown in Figure 2;

Examples of such fillers include carbon-based substances such as carbon black and graphite; inorganic substances such as clay, silica, talc, calcium carbonate and magnesium carbonate; and metal oxides such as titanium dioxide and No. Examples include metal salts such as magnesium hydroxide and aluminum hydroxide. On the other hand, as fibers other than net-like fibers, bulky porcelain fibers are suitable, and nonwoven 45, felt, etc. are suitable for θf. It is preferable that this fiber be formed into a bulky plate having a certain thickness and composited with a resin.

方法が有力であると考えられる。Various methods can be used to produce the impact-absorbing flooring material of the present invention, depending on the physical properties of the vI surface, plywood, and resin composite. Since the resin composite has thermoplasticity, a heating IfX method such as a hot press or a hot roll is generally used. For example, the resin composite can be placed between the water-based surface material and the plywood in the form of powder, pellets, or chunks and heated and pressed to directly attach the flooring material, or the resin composite can be preformed into a sheet of a predetermined thickness. A method of laminating this between a wood-based surface material and plywood and then heat-pressing this laminate,
Alternatively, the resin composite may be extrusion coated onto a water-based surface material or plywood, and then the other wood-based surface material or plywood is bonded by μ-pressing. In addition, as a method that does not use a direct heating process such as heat press or heat roll, there is also a method of induction heating and pressure bonding when the resin composite contains metal substances such as ferrite and iron. . Whichever method is used, from the viewpoint of productivity and yield, it is thought that the most effective method is to provide the resin composite in the form of a sheet between the water-based surface material and the plywood.
