Therefore, in the present invention, a cushion material is interposed between the cured base material and the surface material. When integrally molding a laminated interior material for automobiles with a roughly three-layer structure by heat compression in a mold in the presence of an appropriate adhesive or catalyst, the mold of the desired shape is impregnated with a liquid curable polyurethane resin. After positioning a base material containing a carrier, an interference prevention material, a cushion material, and a surface material in this order, they are integrally molded simultaneously by thermal compression. For this purpose, the interference prevention material is made of a liquid curable polyurethane resin so that the interference prevention material can be integrally molded between the base material and the cushion material without using any adhesive. When it is made of a material that has an affinity for reaction curing, when a reinforcing material or reinforcing agent is used in combination with the base material to obtain better hardness, when a polyurethane prepolymer is used as a liquid curable polyurethane resin for convenience in molding, etc. It is included.

In the conventionally commonly used method, a material having essentially a certain degree of hardness, such as a wood board, is formed into a desired shape and prepared in advance as hardened base materials 1 and 11, and cushion materials 3 and 13 are applied to this. Since it is a method of integrally molding the surface materials 2 and 12,
As mentioned above, there are drawbacks in molding efficiency and shape adaptability. In addition, the laminated materials already provided by the present inventors are molded simultaneously using base materials that have shape adaptability before molding and become cured base materials 1 and 11 after molding. However, the liquid curable polyurethane resin in the base material during hot compression is impregnated and hardened, causing the cushion materials 3 and 13 and the surface to be cured. Some of the materials 2 and 12 were adversely affected.

First, a cure material, which is a precursor material for a cured base material after molding, is prepared. This base material is relatively flexible and highly adaptable to shape before molding, and hardens after molding by hot compression. Such a base material can be obtained by impregnating a carrier such as soft polyurethane foam, coarse felt, glass mat, palm lock or paper with a curable polyurethane resin in liquid form.

After curing by thermal compression, the base material thus obtained functions as a laminated interior material for automobiles to support cushioning materials and surface materials. A reinforcing material such as gold cloth, non-woven cloth, wire mesh, or paper is superimposed on a carrier, or a reinforcing agent made of inorganic powder such as glass chips or shirasu balloons is mixed into the liquid curable polyurethane resin as described above. It is better to use something that has been impregnated with something.

On the other hand, similar to the base material, a flat cushion material, a surface material, and a suitable interference prevention material are prepared. As the cushion material, flexible polyurethane foam and other similar synthetic resin foams can be used, and as the surface material, cloth or leather can be used. As interference prevention materials, non-woven fabrics,
Various materials can be used, such as cloth, paper, and synthetic resin films, but it is especially convenient to use compatible materials that do not require adhesive to integrally mold this interference prevention material. It is. Such compatible materials include non-woven fabrics, cloths, papers, synthetic resin films with appropriate micropores, etc., and the liquid curable polyurethane resin in the base material is simultaneously molded by heat compression. If it is not necessary to have a negative impact, it will not be impregnated into the cushion material or surface material and react and harden, but if it is necessary, it will be transferred to the interference prevention material to the extent that the interference prevention material is integrally molded between the base material and the cushion material. It is a material that reacts and hardens.

Next, the base material, interference prevention material, cushion material, and surface material are sequentially positioned in a mold having a desired shape. At this time, adhesive is applied to one contact surface between the interference prevention material and the cushion material and one contact surface between the cushion material and the surface material when no compatible material is used.
For example, a well-known prepolymer for flexible polyurethane foam is coated, and a catalyst, such as a water-soluble 3
