The present invention relates to a method for producing a laminated skin material which has a buffering function against the resin temperature and molding pressure during shaping of the base material, and has excellent bondability to the base material.

一体化する方法等が知られている。Conventionally, in products used for vehicle interior parts such as door trims and pillar trims, a layer made of synthetic resin foam is used as an intermediate layer on two sides of a highly rigid resin-formed base material.
A laminate with a soft surface synthetic resin sheet as a skin layer is used, but the method for producing the above member is as follows: (1) The laminate and the highly rigid resin base material are separately bonded together. After molding and shaping, an adhesive layer is formed on the surface of the base material, and then the two are bonded and bonded; or (2) only the base material is pre-molded and shaped, and then the base material is A method of forming an adhesive layer on the substrate, shaping the laminate using a forming method such as vacuum forming, and simultaneously bonding and fixing it to the upper surface of the shaped substrate; or (3) combining the above-mentioned unformed substrate with There is a method in which the laminate is pre-laminated and integrated to form a three-layer structure, and then this is molded and shaped. At the same time as forming, a method is known in which the above-mentioned laminate is placed on a master mold and formed and shaped using a vacuum forming method, a pressure forming method, or a press forming method, and is joined and integrated.
しかしながら（１）の方法を用いて製品を得ると上記し

賦形基材上に接着剤層を形成するため、該接着層形成の
ためにスプレー装置、乾燥装置を別個に併置する必要が
あり、コスト面、経済性の点において問題が生じる。However, when a product is obtained using method (1), as mentioned above, the shaping base material and the laminate are manufactured separately, so the shrinkage that occurs during molding of both is different, so it is difficult to adjust the dimensions. However, although the above method (2) was developed to improve the shortcomings of (1), this method does not require the use of the above-mentioned shaped base material. In order to form the adhesive layer, it is necessary to separately install a spray device and a drying device in parallel for forming the adhesive layer, which causes problems in terms of cost and economy.
又上記（３）の方法においてはこれ等の上記の欠点を改

好ましくない構造的に重大な欠陥を有するものである。In addition, the method (3) above was developed to improve the above-mentioned drawbacks, but since the three-layer structure described above is a composite of materials with different moldability, there are problems during molding. There are restrictions on the compatibility of the molding conditions and the shape of the molded product, and the drawing pattern given to the skin layer before molding disappears at the heating temperature under the above-mentioned shaping conditions. The method uses a method in which a concavo-convex pattern opposite to the drawing pattern is formed on the upper surface of the shaping mold, and a drawing pattern is formed on the surface of the skin layer at the same time as the above-mentioned molding, so the mold is more compact than other molding methods. There are problems in that the production cost is high and special consideration is required in terms of maintenance of the prototype. Also,
Regardless of which method (1) to (3) is used, the layer in contact with the above-mentioned shaped base material is a cushion layer, and the core layer is formed by heating and pressurizing the cushion layer during molding of the above-mentioned laminate. The cell structure is deformed or crushed, and in either case there is a significant structural defect which is undesirable.

問題が発生する。Recently, method (4) has been used as a more advanced method, but in this method, the resin base material is flowed into a mold in a molten state and shaped, and at the same time, the laminate is formed and shaped. In order to bond and integrate, the base resin is bonded to the laminate glue and
Since the nonyon layer (e) is in direct contact with the molten state and molded under high pressure, a problem arises in that the foam cell structure of the cushion layer loses its crushing pressure due to the high temperature and high pressure during molding.

なる等の諸欠点を包有するものである。Therefore, as a method to prevent this, a method of pasting a base fabric, non-woven fabric, synthetic resin sheet, etc. on the back side of the cushion layer has recently been used, but since this method requires the above materials to be newly laminated, The manufacturing cost is high, and there are difficulties in adhesive bonding between the material and the cushion layer, and the material is newly provided, so the above (71)
If the aforementioned method is used to melt the base material resin described above to form the aforementioned base material, and at the same time mold this laminate to form a bonded composite, the bonding adhesiveness between the two will be incomplete and the product may be damaged. As well as giving rise to fundamental serious defects in order to obtain
Due to the presence of the new material, the texture becomes hard, and it has various drawbacks such as wrinkles and tearing during molding, which are undesirable causes of defects.

分なものとなり好ましくない。Therefore, the lower layer foam sheet of the laminated skin material of the present invention is on the back side of the above-mentioned middle layer foam sheet, and has a buffering effect against the heat of the above-mentioned melted base resin and the molding pressure during the above-mentioned in-mold molding. It plays a protective role of alleviating the heat and pressure and preventing the foam cells of the intermediate layer foam sheet from being crushed, and the layer body is bonded to the resin base material in a molten state during the molding. It plays the role of imparting adhesive properties to the substrate and improving bonding properties. Therefore, in the lower foam sheet of the present invention, the foaming ratio of the cross-linked highly foamed polyolefin resin is 10 to 30 times, preferably 15 to 25 times, and the foaming ratio of the polyurethane resin is 20 times.
A foam sheet having a sheet thickness of 0.5 to 3 mm, preferably 1 to 2 mm, is used. The polyolefin resin used in the foamed sheet may be a polypropylene resin alone, a copolymer of a polypropylene resin and a polyethylene resin, or a mixture thereof, and the polyurethane resin may be a single or a mixture of various two-component cross-linked urethane resins. use Even if a foamed sheet made of a resin other than those mentioned above is used for the lower foam sort, it is not possible to obtain the buffering and protective effect for the intermediate layer sheet during the above-mentioned molding, and the effect on the bondability with the molded resin base material is also not satisfied. Therefore, the laminated skin material which is the object of the present invention cannot be obtained. In addition, if the foaming ratio of the lower foam sheet is less than 10 times in the case of polyolefin resin or less than 20 times in the case of polyurethane resin, problems will arise in the bondability with the molding base material and the sheet will become hard. When used as a molded interior part after the above molding, the texture becomes hard and causes visual defects such as wrinkles, which is undesirable.In addition, the foaming ratio is 30 times or more in the case of polyolefin resin, and 50 times or more in the case of polyurethane resin. In this case, although the above-mentioned moldability and bondability are satisfied, the buffer protection effect becomes insufficient, which is not preferable.

The thermoplastic synthetic resin sheet used for the sheet includes polyvinyl chloride, polyvinyl acetate, polyurethane, etc. alone, a mixture thereof, or a copolymer thereof, or soft vinyl chloride and AS resin,
A resin made of a mixture of AAS resin, ABS resin, nitrile rubber, acrylic rubber, etc. is used as the colored sheet. The sheet must have a thickness of 0.2 to 1.5 am, and a surface hardness of 40 to 80 in terms of surface hardness. If the thickness is 0.2 mm or less and the surface hardness value is 40 or less, problems will occur with the scratch resistance, abrasion resistance, and formability of the product, which is undesirable.
If the surface hardness value is 80 or more, it will be heavy and hard, which will impede weight reduction and softness, and it will not be possible to obtain a 7-yap shape during molding. The purpose of the invention cannot be achieved. The method for forming the skin layer sheet is to form the thermoplastic resin into a sheet using a calendering method or an extrusion method, apply a squeeze pattern or a printing pattern to the surface of the sheet, and then apply heat to the upper surface of the intermediate layer foam sheet. Either the lamination method or the adhesive bonding method is used to laminate and integrate, or the coating method is used to obtain a sheet-like product with a shibori pattern using a patterned paper pattern, and then one of the above bonding methods is applied to this. A laminate may also be formed. Further, the drawing pattern or printed pattern may be formed on the skin layer sheet after forming the above-mentioned laminate.
