付けする積層体の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a laminate in which a face material is integrally laminated on one or both sides of a synthetic resin foam by thermal compression molding, and a sharply uneven shape is formed.

どの欠点を有していた。Conventionally, thermoplastic resin films, leather, woven fabrics, non-woven fabrics, etc. are adhered to one or both sides of synthetic resin foam.
i-fusion bonded and integrated layer to 3 with an uneven pattern
Laminated bodies of layers are used as vehicle interior materials, furniture materials, wall materials, floor materials, etc. Normally, such laminates are manufactured mainly by the high-frequency welding method, but this method is economically disadvantageous because it requires a very high-cost special form and an expensive welding machine. Ah,
Furthermore, it has the disadvantage that the surface material that can be used is limited to vinyl chloride or the like.

る方法が提案されている。On the other hand, there are methods in which a special foamable curing resin is applied to the surface of the foam and then heat-compressed and molded, or a thermoplastic resin composition is applied to the surface of the foam and then hot compression molded. A method is proposed.

有していた。また、後者の方法は熱可塑性樹脂を用いる
ため、得られる製品が熱に対して可逆的に硬化−軟化を
繰シ返す性質を持ち、形状の安定性の点で劣るという欠
点を有していた。However, the former method requires a complicated process in order to foam and harden the foamable curable resin, and has the restriction that the coating process and the curing process must be performed consecutively. In addition, since the latter method uses thermoplastic resin, the resulting product has the property of repeatedly curing and softening in response to heat, and has the disadvantage of poor shape stability. .

得ることが困難であった。Furthermore, laminated materials used for vehicle interior materials and furniture materials are often required to have sharp three-dimensional shapes, such as sharp corners and recesses that continuously change width. However, with the conventional methods described above, it was difficult to obtain a desired shape.

状を得られることを見い出して本発明に至った。In view of the above circumstances, the present inventors have realized that a cost-effective thermal compression molding method can be applied, and that it is possible to easily and reliably form synthetic resin foams and face materials without requiring special forms or special processes. As a result of conducting intensive research to develop a method that can form the desired three-dimensional diagnostic scissors with high precision and laminate them together, we found that the synthetic resin foam and the face material were pre-coated with lactam on at least one side. The inventors have discovered that a good shape after molding can be obtained by forming a layer consisting of the same material, laminating the same, and then hot compression molding, thereby leading to the present invention.

On the other hand, if the value exceeds 0 o f / m', although the effects of molding properties and heat fusion properties can be obtained, excess lactams may seep into the base fabric, and it is also disadvantageous in terms of cost. In addition, this is not preferable because the foam surface becomes hard, leading to a worsening of the feel. When forming a layer made of lactams on the surface of a foam, it is preferable to allow the lactams to penetrate into the foam by at least 1/2mm, thereby ensuring reliable thermal adhesion and excellent V-temperature. can be obtained.

層体を得ることができる。The thermal compression molding of the foam and the facing material may be carried out continuously using a shaping roll or a shaping conveyor, or may be carried out in a batch manner using a mold or a hot press machine. Furthermore, in the method of the present invention, after the hot compression molding mold is removed, the lactams are added to the laminate in the same shape as the mold at a temperature lower than the melting point of the lactams, before reacting and hardening. By fitting and pressing the molds, it is possible to reliably prevent the uneven shape from deforming, and molding by coating with lactams improves the properties and gives a sharp shape. By molding, a laminate can be obtained.

力の経時的劣化は起こシ難いものと思われる。It is interesting to note that the adhesive layer between the foam and the face material, which are laminated together by the method of the present invention, gradually increases in adhesive strength when left in a moist heat or heat environment. It has been found. Therefore, it is considered that the molded laminate obtained by the method of the present invention is unlikely to suffer from deterioration of the adhesive force between the foam and the facing material over time during actual use.

When cured, it improves the adhesion between the foam and the facing material, and excellent molding imparts properties, resulting in a laminate molded product that has the desired sharp uneven shape even under low compression temperatures and short compression times. can be obtained easily and reliably, and at the same time, the productivity is improved, and the effects can be achieved in that it can contribute to energy saving in the process. Furthermore, as the properties of molding have improved, it has become possible to manufacture laminates with three-dimensional shapes, which was difficult with conventional methods, and it has great industrial and practical value in terms of design. It is expensive.

追従できず、所望の寸法が得られなかった。Table 2 As can be seen from the measured dimensions in Table 2, the laminates of the examples were molded with values much closer to the ideal values than those of the comparative examples. This is because the elongation rate of the example is sufficiently large as a surface material, and the coO% modulus is 2! This seems to be due to the fact that it has good followability to the mold because it uses a sufficiently small g/m. On the other hand, in the laminate of the comparative example, since the elongation rate of the front side material was small, it could not follow the mold during molding, and the desired dimensions could not be obtained.

Molding is a method for producing a laminate, which is characterized by forming a layer made of lactams on one or both of the surfaces of the facing material prior to lamination. The layer consisting of the lactams has a 7-layer laminated portion between the synthetic resin foam and the facing material. The manufacturing method according to claim 7, which is the above. 3 The surface to be molded has an elongation rate of /00% or more, p, roo% tensile strength, tensile sillage kg/cIf
The manufacturing method according to claim 1 or 2m, which is less than or equal to L.
