Abstract

(57) [Summary] [Purpose] To obtain sufficient soundproofing performance. [Structure] A cushion layer 3 is provided on the back surface of the substrate 1 of the flooring material. and a synthetic fiber nonwoven fabric 3a made of hollow synthetic fibers.
The cushion layer 3 is composed of two layers: and the rubber cushion material 3b. A sufficient soundproofing effect can be obtained with the synthetic fiber nonwoven fabric 3 made of hollow synthetic fibers.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a soundproof flooring material with a structure that absorbs vibrations and provides soundproofing. be.

0002

[Conventional technology]

In conventional soundproof flooring materials, as shown in Figure 6, the surface of the substrate 1, such as plywood, is It is formed by pasting decorative plywood 2 and pasting rubber cushion material 3' on the back side of the board 1. .

0003

[Problem that the idea aims to solve]

In the conventional soundproof flooring material mentioned above, a rubber cushion material 3' is pasted on the back side of the substrate 1. Because of this, the rubber cushion material 3' can absorb vibrations and provide soundproofing. However, if only the rubber cushion material 3' was used, the soundproofing performance was insufficient. This invention was made in view of the above problems, and the purpose of this invention is Our objective is to provide a soundproof flooring material that provides sufficient soundproofing performance.

0004

[Means to solve the problem]

In order to achieve the above purpose, the soundproof flooring material of the present invention has a cushion on the back side of the substrate 1 of the flooring material. In the soundproof flooring material provided with layer 3, synthetic fiber nonwoven fabric 3a made of hollow synthetic fibers and The cushion layer 3 is composed of two layers including the rubber cushion material 3b. Ru.

[0005]

[Effect]

A large vibration absorption effect can be obtained with the synthetic fiber nonwoven fabric 3a made of hollow synthetic fibers. , the soundproofing performance can be greatly improved due to the synergistic effect with the rubber cushion material 3b.

[0006]

【Example】 In the case of the soundproof flooring material of the present invention, a plurality of elongated flooring pieces 4 are combined in a step-like manner as shown in Fig. 1. , are formed as shown in FIGS. 2 and 3. Flooring piece 4 is assembled as shown in Figure 4. A damping sheet 5 is laminated on a board-like substrate 1, and a decorative plywood 2 is placed on top of the damping sheet 5. It's layered. The substrate 1 is a grooved plywood with appropriate cut grooves 6 formed therein. decorative plywood 2 is a decorative board with a veneer such as Nara affixed to the surface. The vibration damping sheet 5 is a vibration damping sheet. The composition is as shown in Table 1.

[0007]

[Table 1]

[0008] The cushion layer 3 is made of a synthetic fiber nonwoven fabric 3a and a rubber cushion material as shown in FIG. 3b and are bonded together using a hot melt nonwoven fabric 3c. this cushion Layer 3 is bonded to the underside of substrate 1 over a plurality of flooring pieces 4 . Synthetic fiber The nonwoven fabric 3a is made of synthetic fibers of 8 to 10 deniers with an irregular hollow cross-sectional shape. For example, it has the specifications shown in Table 2.

[0009]

[Table 2]

0010 Further, the specifications of the rubber cushion material 3b are as shown in Table 3, for example, and the rubber cushion material 3b is as shown in Table 3. The material composition of material 3b is according to the specifications in Table 4.

[0011]

[Table 3]

0012

[Table 4]

[0013] In addition, a notch is provided from the back side between 4 adjacent flooring pieces, and this notch At the same time, an elastic material 9 such as urethane rubber is loaded and connected. Elastic material like this When connected through the elastic material 9, vibrations are absorbed by the elastic material 9 and transmission of vibrations can be prevented. The soundproof flooring constructed as above is installed directly on the concrete slab. Adjacent soundproof flooring materials are connected by fitting the female part 10 and the male part 11 at the ends. Prevention When the sound bed material is installed, the synthetic fiber nonwoven fabric 3a of the cushion layer 3 and the rubber cushion The vibrations are sufficiently absorbed by the damping agent 3b, and a sufficient soundproofing effect can be obtained.

[0014]

[Effect of the idea]

As stated above, the present invention is a synthetic fiber non-woven fabric made of hollow synthetic fibers and a rubber cushion. Since the cushion layer is composed of two layers with the cushioning material, the cushioning layer is composed of two layers: A large vibration absorption effect can be obtained with the synthetic fiber non-woven fabric, and the vibration absorption effect of rubber cushion material is Combined with this, sufficient soundproofing performance can be obtained.
