材３を圧着させることにより積層一体化させ−ている。As a soundproof flooring material, the present inventors cut a plurality of grooves 2 from the back side of the board 1 toward the front side as shown in PIS 4, and sequentially cut non-woven fabric and 7-Sitan material on the back side of the board 1. 3 and foam rubber sheet 4 are laminated to create a VT-type product. In this case, the nonwoven fabric material 3 and the foamed rubber sheet 4 are placed on the rubber sheet 8 when the rubber sheet 8 is carried into the hot air stove 11 by the belt conveyor 10 and foamed, as shown in Figure MS4. 3 is supplied, and the foamed rubber sheet 4 and the nonwoven cushion material 3 are pressed together by a weight roller 12, thereby making them integrally laminated.

ことがない防音床材の製造方法を提供することにある。In the conventional method, the temperature inside the hot air stove must be as high as 180 to 200°C, so the nonwoven cushion material 3 may shrink due to the hot air, and the nonwoven cushion material 9 may be supplied on the rubber sheet 8. As a result, heat transfer to the rubber sheet 8 deteriorates, and the speed of the belt conveyor 10 in the MK furnace 11 has to be reduced, resulting in low productivity. Wrinkles occurred during compression due to the difference in the amount of contraction of cushion material 3. The present invention has been made in light of the above circumstances, and its objectives are to reduce the thermal shrinkage of a non-woven Cushitan material, increase the foaming speed of a foamed rubber sheet,
To provide a method for manufacturing a soundproof flooring material without reducing productivity and causing no wrinkles when bonding a foamed rubber sheet and a non-woven cushion material.

に際してしわが発生することもな′ｖ１。The present invention is a method for manufacturing a soundproof flooring material, in which a plurality of grooves 2 are cut from the back side of a substrate 1 toward the front side, and a nonwoven Cushtan material 3 and a foamed rubber sheet 4 are sequentially laminated on the back side of the substrate 1. The rubber sheet 8 is heated and foamed to form a foamed rubber sheet 4, and the hot-melt nonwoven fabric 9 is melted by the amount of heat retained in the foamed rubber sheet 4, and the nonwoven cushion material 3 is laminated and integrated. This configuration solves the above problem S. [Function 1: The hot melt nonwoven fabric 9 is melted by the amount of heat held by the foamed rubber sheet 4 f; Since the woven fabric cushioning material 3 is laminated and integrated, the nonwoven fabric cushioning material 3 does not shrink due to heat, and the foamed rubber sheet 4, heat transfer is not deteriorated by the nonwoven cushion material 3 during foaming, and wrinkles do not occur when the nonwoven cushion material 3 and the foamed rubber sheet 4 are compressed. [Example 1 The substrate 1 is made of a plywood 5 with a thickness of 2.5 to 4 mm, for example.
．． The plywood 5 of this substrate 1 is provided with a plurality of grooves 2 from the back side to the front side. The kerfs 2 are provided in a grid pattern. For example, the kerf 2 has a width of 3III1 and is cut at a pitch of 60 mm. This cut WIt2 does not reach the surface of plywood 1 with soil. A vibration isolating sheet 7 is interposed between the plywood 5 and the veneer 6 of the substrate 1. The vibration isolating sheet 7 is made of a soft material such as nonwoven fabric, natural rubber, Hewei rubber, urethane resin, silicone resin, etc., and usually has a thickness of 11 mm or less. in this case,
By raising the rubber instep of a synthetic rubber sheet such as an N-sized sheet or an SBR sheet, it is possible to further rebound impact and improve vibration isolation. On the back side of the plywood 5 of this board 1, 2 to 2.5 ml II
A nonwoven cushion material 3 with a thickness of 2.5 to 4 mm and a foamed rubber sheet 4 with an open thickness of 2.5 to 4 mm are laminated. The nonwoven cushioning material 3 is made of polyester, for example, and the foamed rubber sheet 4 is made of natural rubber with 60 to 801% by weight of SRR synthetic rubber.
In addition, a rubber sheet 8 formed from vulcanization (including a foaming agent) and a softening agent is foamed. The nonwoven cushion material 3 and the foamed rubber sheet 4 are laminated and integrated in the following manner. As shown in FIG.
The foamed rubber sheet 4 is carried into the hot air stove 11 and foamed to form the foamed rubber sheet 4. The back side of the foamed rubber sheet 4 protrudes in a lattice shape as shown in FIG. 3 due to the wire mesh belt of the belt conveyor 10. The inside of the hot air stove 11 is around 190℃ +1! ! It's in order. Foamed rubber sheet 4 is hot air stove 1
Immediately after being carried out from 1, on the foam rubber sheet 4,! 5
Boryamide-based hot melt nonwoven fabric 9 is placed on the back side shown in Figure 2.
is supplied with the nonwoven fabric cushioning material 3 to which is pasted, and the hot melt nonwoven fabric 9 is melted by the amount of heat held by the foamed rubber sheet 4 in the heat insulation cover 13 (<1f# melting temperature 70 to 90°C). The foamed rubber sheet 4 and the nonwoven cushion material 3 are crimped and integrated. The soundproof flooring material A manufactured in this way has a soundproofing property h'L
45 L/h, and is laid on a concrete surface such as a concrete slab of a building by adhering it with an adhesive. Effects of the Invention 1 The present invention provides a method for manufacturing a soundproof flooring material in which a plurality of grooves are cut from the back side of the substrate toward the front side, and a nonwoven fabric cushioning material and a foamed rubber sheet are sequentially laminated on the back side of the substrate. A foamed foam is formed by heating and foaming a rubber sheet, and the heat retained in the foamed rubber sheet melts the hot-melt nonwoven fabric to integrate the nonwoven cushioning material, so that the nonwoven cushioning material does not shrink due to heat. There is no
Furthermore, when foaming the foam rubber sheet, the non-woven cushion material does not deteriorate heat transfer and reduce productivity, and wrinkles do not occur when the non-woven cushion material and the foam rubber sheet are pressed together.
