Specifically, by pulverizing scraps such as skin materials, knitted woven fabrics or non-woven fabrics, and polyurethane foam, and integrally molding mixed chips and a foaming solution of polyurethane with intermediate materials such as polyurethane slabs, coarse wool, and gold cloth. The present invention relates to a method for manufacturing a composite pad material.

ていないので省資源の上からも重要である。 Conventionally, cushion materials for automobile seats, chairs, etc. have been produced by foaming polyurethane either integrally or separately with skin materials such as polyvinyl chloride leather and synthetic leather, and knitted or non-woven fabrics. It is used. For this reason, a large amount of waste is generated during production, and a large amount of waste is also generated when scrapping cars, but not only is the disposal of this waste problematic in terms of environmental pollution, but it is not recycled because it is not recycled. It is also important from a resource perspective.

有の固い感触感はとれず、特に表面層における初
期感触は極めて悪かつた。 In order to solve this important problem, we impregnated a mixed chip made by crushing polyvinyl chloride leather, knitted or nonwoven fabric, and polyurethane foam with a foaming solution of polyurethane foam at 10 to 50% of the chip weight. A method of manufacturing a composite pad material by performing post-foaming has been proposed (Japanese Patent Application Laid-open No. 101456/1983). As shown in FIG. 1, the composite pad 1 thus obtained is constructed by filling the space between the polyvinyl chloride leather chip 2, the knitted fabric or non-woven fabric chip 3, and the polyurethane foam chip 4 to bond them together. It has become a state. However, such a composite pad material currently has not only highly elastic polyurethane foam layers 4 and 5 on its surface, but also polyvinyl chloride leather chips 2 and knitted or non-woven fabric chips 3, which are much harder. Because of this, the surface is rough and has many irregularities, and the roughness becomes especially noticeable when pressed. Therefore, in the seat assembly state, the seating surface feels extremely uncomfortable. Furthermore, even when scraps of soft foam material such as polyurethane foam are used alone as a chip material, the surface area is less uneven than when using the mixed chips, but the hard feeling peculiar to chips cannot be obtained, especially in the surface layer. The initial feeling was extremely poor.

という欠点があることが判明した。 In order to improve such poor tactility, the present inventors added a polyurethane foam slab between the composite pad material 1 and the skin material 6, as shown in FIG.
The surface material 6 is formed by interposing coarse wool, gold cloth, etc. 7, and by attaching the slab, coarse wool, gold cloth, etc. 7 to the surface of the composite pad material 1 using an adhesive 8 as shown in FIG. We investigated methods of intervening between the two. However, in the former case, not only is the work of interposing the slab 7 etc. complicated, but there is also a risk that wrinkles may be formed due to displacement during use, and there is no integrity with the composite pad material 1. As shown in the figure, first the skin material 6 and the slab 7
etc. are deformed, the surface of the composite pad material 1 feels like a foreign body, which has the drawback of poor initial feel. On the other hand, since the latter uses adhesive 8, not only is the workability further reduced, but also a skin layer of hardened adhesive 8 is formed between the composite pad material 1 and the slab 7, etc. As shown in FIG. 5, it was found that the initial deformation of the skin material 6, slab 7, etc. was larger than that of the composite pad material 1, and the initial feel due to the foreign body sensation was further deteriorated. .

This is a method for manufacturing a composite pad material, which is characterized in that the material is poured onto an intermediate material such as a slab, coarse wool, gold cloth, non-woven fabric, etc., and then heated under pressure to foam the foaming stock solution and integrally mold it.

An intermediate material 10 such as a polyurethane foam slab or nonwoven fabric is placed and set on the bottom surface of the container. On the intermediate material 10 thus set, a mixed chip material 11 obtained by adding 10 to 60%, preferably 20 to 40%, of a foaming stock solution of polyurethane foam to the mixed chip as described above and stirring and mixing the mixture, Fill as shown in FIG. Next, as shown in FIG. 8, the upper mold 12 for molding is closed, and 1 kg of chip material is compressed with a pressing force of 1 to 50 kg/cm 2 , preferably 3 to 25 kg/cm 2 , and heated to a predetermined temperature, for example, 50 to 25 kg/cm 2 . 150℃, preferably 70
By heating at ~145°C for 2 to 20 minutes, preferably 3 to 10 minutes, the foaming stock solution impregnated in the mixed chips foams while bonding the chips together.
As a result, as shown in FIG. 9, a composite pad material in which the intermediate layer and the pad layer 1 are integrally bonded is obtained. The heating and pressurizing step may be carried out in a steam atmosphere, or may be carried out by adding an amine aqueous solution or the like to the foaming stock solution.

て良好となる。 As described above, in the method for manufacturing a composite pad material according to the present invention, a foaming stock solution of polyurethane foam is added to chips made by crushing scraps of skin materials, knitted woven fabrics or non-woven fabrics, polyurethane foam, etc. to the weight of the mixed chips. The impregnated mixture thus obtained is poured onto an intermediate material such as a polyurethane foam slab, coarse wool, gold cloth, or nonwoven fabric that has been set in advance on the inner surface of the lower mold, and then processed. Since the foaming stock solution is foamed by pressure heating and integrally molded, the resulting composite pad material is free from the appearance of foreign substances such as hard skin material present on the surface of the pad layer due to the intermediate material. In addition, the manufacturing process can be extremely simplified. Particularly at the initial stage of pressing, as shown in FIG. 10, the intermediate material 10 and pad layer 1 are bonded with the same polyurethane foam, giving a sense of unity, and the pad layer also deforms in sync with the deformation of the intermediate material 10. Since the pad layer 1 is deformed to some extent, the hard material on the surface of the pad layer 1 becomes difficult to feel. Therefore, the initial feel is extremely good.

材を提供し得るものである。 Further, since the intermediate material is used for the mold surface, a mold release agent is not required, so workability is greatly improved. A further advantage is that the hardness of the resulting composite pad material can also be partially varied by varying the partial input amount of the mixed chip material. Furthermore, since the intermediate material can be selected arbitrarily, cushion materials with a wide variety of variations and no surface irregularities can be obtained. Furthermore, since the method of the present invention enables the reuse of industrial waste, it is extremely useful in terms of resource conservation and pollution prevention, and can provide cushion materials at extremely low cost.
