材を既に提供している。 By the way, the present inventors have developed this type of material by using a conventionally commonly used method of forming a hardened base material in a separate process using a material such as wood board, which essentially has a certain hardness. In view of the drawbacks of laminated interior materials, in order to improve the molding efficiency and shape adaptability, a liquid carrier is used which is inherently flexible and therefore has excellent shape adaptability when molded into the desired shape. A laminated interior interior for an automobile in which a base material, which is a precursor material of a hardened base material, including one impregnated with a curable polyurethane resin, is prepared, and the base material, cushion material, and surface material are simultaneously integrally molded by heat compression.

まれている。 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.

んだものがある。 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.

ことにより得られる。 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.

Isocyanates such as tolylene diisocyanate and polymethylene polyphenyl polyisocyanate,
It consists of a crosslinking agent and the like, and these can be foamed and hardened by adding a catalyst and, if necessary, water as a foaming agent. A polyurethane prepolymer, which is formed by reacting the polyol and the isocyanate in advance, is more preferable because it is easy to handle and cures quickly.

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.

移行して反応硬化するような材料である。 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.

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
